What is the advantage or disadvantage of JST connector using in the wire assembly?
JST connector is the world's largest terminal production and sales center in the connector industry. The company is headquartered in Osaka, Japan. The company not only has rich product types and constantly updated production technology, but also is a very popular terminal manufacturer all over the world. The connectors produced by the company are used in all fields of our life. So do you know the advantages and disadvantages of JST connector?
When the connectors are produced, they have to go through injection molding. Do you know the common defects and causes of injection molding of JST connectors? In fact, the common forming defects of JST connector are as follows: the plastic parts have black spots or black liquid, the surface is uneven, spills, the plastic parts are not fully formed, bubbles or scorched, deflated, jointed or pressed into the mold of the plastic parts, etc. The main reason is the factors of injection molding machine, mold and material.
So what do you know about the composition and performance of JST connector contacts? Bonding material: the plug is made of metal bonding material. Generally, brass bonding is mainly used, but the phosphorus bronze, beryllium copper, etc. with high insertion times and long service life are required.
When connected to the JST connector, the pin will be expanded by absolute force, but it is easier to separate. Therefore, the connection strength of JST connector is greater than the separation strength.
In this way, the interaction of insertion and extraction forces can easily lead to the loss of JST connector. If you want to reduce the loss, you can look at the following good methods: you can improve the contact surface strength of the gold plating layer, which can effectively reduce the friction. The contact surface can be plated with nickel before gold, which produces less friction than gold plating directly on copper.
Let 's talk about how to choose the JST Connector.
1. PH series strip connector
PH series strip connector (commonly known as ph2.0) is a classic series of JST and is widely recognized by the market.
Provide four types of straight needle, curved needle, vertical paste and horizontal paste for customers to choose.
Applicable: current 2a, voltage within 100V.
Type selection suggestions: 6 pin and below are general pins, followed by 7-10 pin, and above 10 pin is not recommended.
2. PA series strip connector
PA series is a new product developed by JST to replace pH series. It adds the design of latch and guide groove, which is superior to pH Series in all aspects.
Applicable: current 3a, voltage within 250V.
Type selection suggestions:
(1) 6pin and below are universal pins, followed by 7-10pin, and more than 10PIN is not recommended
(2) Try to choose without positioning.
3. XH bar connector
XH bar connector (commonly known as xh2.5 / xh2.54), the classic series of JST, is widely recognized by the market.
Provide four types of straight needle, curved needle and horizontal paste for customers to choose.
Applicable: current 3a, voltage within 250V.
Type selection suggestions: 6 pin and below are general pins, followed by 7-10 pin, and above 10 pin is not recommended.
4. XA bar connector
Xa series is a new product developed by JST to replace XH series. It adds the design of latch and guide groove. It is superior to pH Series in all aspects.
Applicable: current 3a, voltage within 250V.
Type selection suggestions:
(1) 6pin and below are universal pins, followed by 7-10pin, and more than 10PIN is not recommended
(2) Try to choose without positioning.
5. VH series strip connector
VH series strip connector (commonly known as vh3.96), the classic series of JST, is widely recognized by the market.
Straight needle and curved needle are available for selection.
Applicable: current 10A, voltage within 250V.
