Light and short power connector

This creation is a light and short power connector, especially one that can reduce its volume and has the effect of avoiding the increase in impedance, causing sparks or burning, making it more practical.

An electronic connector application generally has a socket and a plug connector. The plug socket is disposed in an electronic device. The plug connector is provided with a cable at one end and the socket at the other end. , the signal or power supply has been completed.

The power connector of the prior art is used for powering a pair of connector connectors. The power connector has a receiving cavity and a positive terminal and a negative terminal in the receiving cavity. The docking connector also has a positive pole and a positive pole. The negative pole, when the mating connector is normally inserted into the receiving cavity, after the negative poles are in contact, the positive pole is contacted again to complete the conduction power supply. However, when the operator uses it, if the docking connector is just in contact with the negative pole, and the positive pole is not in contact or the contact is bad, at this time, the connector is prone to high impedance, which causes sparking or burning phenomenon. The service life of the connector is reduced or destroyed. Moreover, the center terminal of the conventional power connector is surrounded by the receiving cavity, so that the volume around it is too large to meet the requirements of lightness, thinness and shortness.

In view of this, the creator is working on the development of connectors in the spirit of excellence and innovation, and created a light and short power connector to make it more practical.

The main purpose of this creation is to provide a power connector that is light and short, and particularly refers to a rectangular connector that is light and thin, making it more practical.

The outer terminal group 14 is located outside the center terminal 12, and is provided with a first terminal 24 and a second terminal 26. In this embodiment, the first terminal 24 is a metal casing and is disposed around the inner wall surface 20 of the receiving cavity 18. Or a metal sheet body (not shown), the first terminal 24 is a negative end having at least one elastic piece 28, and the second terminal 26 is a spring-type signal end, which is disposed in one of the receiving chambers 18 On the stud 23, when the mating connector 3 is inserted into the receiving cavity 18, the center terminal 12 is in contact with the first terminal 1, and the second terminal 2 is located between the first terminal 24 and the second terminal 26, and is connected to the first terminal. 24 and the second terminal 26 are in contact.

The metal outer casing 16 is disposed on the outer wall surface 22 of the receiving cavity 18, and covers the insulating body 10 in contact with the first terminal 24.

Referring to the fourth figure, when the mating connector 3 is inserted into the receiving cavity 18 of the insulative housing 10, the second end 2 of the mating connector 3 first contacts the spring 28 of the first terminal 24 of the outer terminal set 14 first. Five figures, then the first extreme 1 is in contact with the center terminal 12, please refer to the sixth and seventh figures, and finally the second extreme 2 Reconnects to the second terminal 26 of the outer terminal set 14.

If the second terminal 2 contacts the second terminal 26 of the outer terminal group 14, the signal transmission can be started for the power source to be turned on, thereby avoiding the phenomenon of sparking or burning caused by high impedance, thereby improving the service life. And more practical.

Furthermore, the second terminal 2 of the mating connector is located between the first terminal 24 and the second terminal 26 and is in contact with the first terminal 24 and the second terminal 26, so that it can be made thin and short.

The specific embodiments set forth in the detailed description of the preferred embodiments are merely illustrative of the technical scope of the present invention, and are not intended to limit the scope of the present invention to the embodiments. The implementation of all kinds of changes is within the scope of this creation.
