What are the standards for inspecting high current connector pin jacks?

The standards for inspecting the pin jacks of high-current connectors are as follows:

Inspect the requirements of the environment.

Under normal light source conditions, the product is placed on the workbench at a distance of 30 cm and at an angle of 45°**.

Packaging inspection standards.

Each product packaging box and inner box must have the corresponding product name, specification, part number, quantity, and affixed with environmental protection marks, the packaging can not have mixed materials, wrong materials, moisture, deformation of the packaging box, box damage, each product packaging must be corresponding protective measures.

Appearance inspection standards.

There is no deformation, bending, oxidation, staining, etc. in the pins and jacks or conductive parts, and the length and size of the product and the outer diameter are checked within the standard range with vernier calipers and micrometers.

Functional checks. Use a multimeter to detect whether the resistance value at both ends of the conduction is within the standard, put the pins of the product into the 270 5 tin solution furnace for soldering, take it out from the back of the tin furnace, and test its function after 3 hours, which is consistent with the function before the test and has no thermal loss.

Precautions for functional checks:

1.Protective gloves are required for inspection and pick-up.

2.Solderability and soldering heat resistance are subject to 10pcs per batch.

What are the high-performance alloys used for pin jack connectors?

Clause. 1. Any cutting pins that have not undergone cold deformation.

Clause. 2. Good machinability up to 70%.

Clause. 3. High strength is more than 500MPa

Clause. Fourth, the alloy is not suitable for zonal annealing.

Clause. 5. The chips can be mixed with standard lead brass.

Clause. 6. Crimped cold-formed cutting pins do not need to be annealed.

Clause. 7. Medium (62C 62As) to Good (62A 61B) machinability.

Clause. 8. It is recommended to use 62C for cold heading pins.

Clause. 9. Medium strength greater than 380n mm2

Size, material, performance testing, etc., but also pay attention to the size of the fit. Take a look at each customer's requirements. Some customers are demanding, and some customers are simple.

It can be divided into the following categories:

Clause. 1. Connector pin jack.

Clause. 2. Medical pin jack.

Clause. 3. New energy pin jack.

Clause. Fourth, aviation pin jack.

Clause. 5. Automotive electronic pin jack.

If it is a power connector product, the inspection requirements are mainly the following:

1. Shell requirements:

1. Plugging force: 10,000 times through testing.

2. High temperature resistance: high temperature resistance 105 degrees.

3. Low temperature resistance: low temperature resistance to minus 40 degrees.

4. Fire retardant and flame retardant: open flame burning, automatically extinguished within 10 seconds from the source.

Second, terminal requirements:

From the material, copper silver-plated, copper galvanized, copper, aluminum, iron, etc., the performance is stable and generally silver-plated with copper:

Silver: excellent conductivity, good stability, low cost, but easy to be scratched; Generally, the nickel bottom is silver-plated nickel: strong weldability, general conductivity, low cost, the formation of an oxide film layer on the surface, easy to corrode after a long time, not resistant to moisture and smoke.

Gold: The conductivity is the best, the stability is the best, but the cost is high, all three are in order to protect the metal device, according to the harsh environment and industrial cost requirements to choose the type of plating.

1.Structural size: It is important to shape the shape of the connector, because there will be certain space constraints at the product connection, especially the connector on the board cannot be in contact with other parts.

2.Impedance matching: There is no special requirement for the impedance of the connector for general signal transmission, but the RF signal has very strict requirements for the impedance matching, and the impedance mismatch will cause signal reflection, which will affect the signal transmission.

3.Shielding: With the development of electronic products, EMC has received more and more attention, connectors need to have metal shells, and cables need to have shielding layers, and the shielding layer needs to be connected with metal shells to achieve shielding effect.

It is also possible to use the injection molding method to wrap the plug part with copper and weld the shield layer of the cable and the copper skin together.

4.Reliability: Connectors are used to connect signals, so the connection parts should ensure their reliability, such as surface contact is better than point contact, pinhole type is better than sheet spring type, etc.

5.Versatility: When choosing a connector, we should choose a universal object as much as possible, especially between the same series of products, the choice of connector has a strong versatility, which can reduce the type of materials, reduce costs and supply risks.

6.Durability: Some connectors work in a very complex environment, in order to ensure their stable performance, it is necessary to ensure that they can adapt to complex environments, otherwise not only can not work well but also may be dangerous.

Among them, high temperature resistance, corrosion resistance, salt resistance, mold resistance, etc. are common and important indicators.

The above points are the inspection requirements of the connector, in the test of BTB FPC connector, a high-current shrapnel microneedle module is needed as a connection to ensure the stability of the test. It has a bearing capacity of up to 50A in current transmission, and has an average service life of 20W times, with high accuracy, small impedance and strong connection function.

1. Threaded connection method, which is often used in connector pins and jacks with large size contacts and working in strong vibration environments. After the connection is completed, it can be installed with a fuse or nut to prevent loosening, which is reliable to use, but the continuous and unloading speed is slow.

2. The bayonet connection method is a reliable and fast form of connection and separation. Most of the electrical connectors in the form of the Card 121 connection have a visual display of the correct connection and locking, which can be seen from the small hole on the side of the electrical connector connection nut.

3. The plug-in connection method is a multi-purpose connection form. The common plugging connection has two kinds of structures, ball or pin, because there is no mechanical labor-saving mechanism, once the plug is mistaken, the mechanical resistance increases significantly, and can be found in time.

4. The cabinet connection method is used for the electrical connector on some equipment that needs to be blindly connected close to the frame, which can make the electrical equipment lighter and smaller, easier to maintain and more reliable. Connector pins and jacks are typically constructed with a floating or elastic contact design to ensure their proper connection.

There is a high-current shrapnel microneedle module that is a one-piece shrapnel design, which only needs to touch the DUT with one end and conduct signal transmission at the other end, which has a strong connection function. When the current is transmitted, it circulates in the same material, which is stable and reliable, and after gold plating and hardening, the shrapnel has better conductivity and a longer service life.

The environmental resistance of the electrical connector is improved by the insulator and the interface sealing body. In order to adapt to the high temperature, low temperature and flame retardant of the product, it ensures the stability and reliability of the geometric dimensions of the parts. Most insulators are molded with thermoset plastics.

The interface sealing body and wire sealing body are molded with silicone rubber. Contacts include male and female contacts, sometimes referred to as pin jacks.

The connection methods are divided into: soldering, crimping, pressing, and winding, etc., to realize the circuit connection.

There are many types of pin jacks, which can be divided into the following according to the shape

Leaf spring pin jack, 2Reed pin jack 3According to the surface treatment of the material, the crown spring pin jack can be divided into: 1. Gold plating 2Silver Plating 3Copper plating 4Tinning.

According to the use, it can be divided into:1Connector pin jack 2Medical Pin Jack 3Aviation Pin Jack 4New energy pin jack.

5.Automotive electronic pin jacks.

What do you need? How much spacing? TXGA pins are available, such as wire-to-board, pin headers, female headers, etc., which can be done.

Automatic vehicle equipment is needed to produce connector jack pins, and if it is a high-standard wire spring hole jack pin, a wire spring hole assembly machine is also required.

The common specifications and models of high-current connectors are JXPSH-10 16W, JXPSH-10 22W, and JXPSH-10 24W

The 16-bit and 24-bit are thickened materials, which can achieve an overload current of 500A per second.

There are many high-current connectors, in general, XT90, XT150, AS150 and so on, but I don't know which product you are talking about. I've seen it on ** before, it's basically produced by ams, you can go to their ** to consult.

There are many types of high-current connectors, depending on which field they are used in, the shape design is different, the use environment is different, and the materials are also different. The size of the installation space determines the connection form, there are push-pull type, bayonet type, threaded connection, you can refer to the official website of Taixing Zhiyuan Electric Company, there are many types of models, customers have a lot of room for choice, conventional products, and they are affordable.

There are many types of pin jacks, which can be divided into two types according to their shapes: leaf spring pin jacks, 2Reed pin jack 3

According to the surface treatment of the material, the crown spring pin jack can be divided into: 1. Gold plating 2Silver Plating 3

Copper plating 4Tin plating can be divided into 1

New energy pin jack 5Automotive electronic pin jacks.

Is it used in lithium batteries, controllers, chargers, or motors? I know that the terminal block XT60U can be plugged and unplugged, and it is possible to pass a high current of 30A.

I know a lot of plug-in connectors, 30A is considered a large current, XT60 seems to be like this, where do you want to use it?
