Description

Electrical connector

This creation relates to an electrical connector, and in particular to an electrical connector that increases the clamping force.

Electrical connectors are widely used in electronics, information, communication, optoelectronics, etc., where the power connector has two terminals and acts as the positive and negative poles of the power supply. The power connector is the positive and negative terminals of the terminal to provide work for the electronic components. Voltage. Generally, an electrical connector socket or a plug is formed at both ends of the cable to form a power supply and a machine combination for connecting a power source and an electronic component at a distance; or the existing power connector may be disposed on the circuit board. And electrically connected to a matching power connector.

However, in the prior art, after the electrical connector is used for a period of time, the clamping force is insufficient, resulting in problems such as reduced reliability of power or signal transmission.

In view of this, it is indeed necessary to improve the grounding structure of the existing power connector circuit to solve the above drawbacks.

In order to solve the problem of insufficient holding power and poor contact in the prior art, the present invention changes the structure of the existing electrical connector, and provides an increase in the holding power of the electrical connector socket and the mating plug, thereby improving the reliability of power or signal transmission. Electrical connector.

The present invention provides an electrical connector that can be plugged and assembled by a plug electrical connector, the outer surface of the plug electrical connector is recessed with an annular groove, and the electrical connector is Contains: an ontology.

The at least one first terminal and the at least one second terminal are fixed to the body, and the first and second terminals are spaced apart from each other by the plug electrical connector.

A shielding shell assembled to the outside of the body.

The first terminal includes a fixing portion, at least one clamping tongue disposed on the fixing portion, a connecting portion extending outward from the fixing portion, a plurality of first contact portions and a plurality of second contacts The first and second contact portions are wound around the outer peripheral side of the second terminal, and each of the first contact portions is bent at a position of the middle portion and a convex portion is stamped and formed there, and the convex portion is The ring is engaged with the annular groove of the plug electrical connector, and the second contact portion abuts the plug electrical connector.

The design of the terminal through the structural design of the terminal greatly increases the holding power of the electrical connector and the mating plug electrical connector, thereby avoiding poor contact, thereby improving the reliability of power or signal transmission.

The above and other objects, advantages and features of the present invention are apparent from the following detailed description of the preferred embodiments.

Please refer to the first figure, which is an exploded perspective view of the present invention. The present invention includes a body 1 and at least one first terminal 2 and at least a second terminal 3 fixed to the body 1. In the present embodiment, the first and second terminals 2, 3 are each one, and the first and second terminals 2, 3 may include other components. Terminal (not shown).

Please also refer to the second figure, which is an exploded perspective view of another perspective view of the present invention. The body 1 has a receiving chamber 10, and a plurality of grooves 11 and one end of the groove 11 are disposed on the inner wall of the receiving chamber 10. A fixing block 12 is provided, the grooves 11 are for mounting the first terminal 2, and the fixing block 12 is for fixing the first terminal 2.

The first terminal 2 includes a fixing portion 20, at least one latching tongue 21 disposed on the fixing portion 20, a connecting portion 22 extending outwardly from the fixing portion 20, a plurality of first contact portions 23 and a plurality of second contact portions 24, the second contact portions 23 being spaced apart from each other between the first contact portions 24 The first and second contact portions 23, 24 are wound around the outer peripheral side of the second terminal 3, and each of the first contact portions 23 is bent at a position of the middle portion thereof, and a convex portion 231 is stamped and formed there. At the same time, each of the second contact portions 24 further includes a bent portion 241. In the embodiment, the first terminal 2 is distributed in such a manner that the two first contact portions 23 are spaced apart from each other by a second contact portion 24.

Please also refer to the fourth and fifth figures, which are respectively a schematic diagram of the docking of the electrical connector and the plug electrical connector, and a sectional view of the assembly; the first terminal 2 and the second terminal provided in the original electrical connector The three connectors have a spacing for inserting a plug electrical connector 5, and the outer surface of the plug electrical connector 5 is recessed with an annular recess 53. When the plug electrical connector 5 is inserted into the original electrical connector, The convex portion 231 of the first contact portion 23 is locked in the annular groove 53, thereby increasing the holding force of the electrical connector and the plug electrical connector 5, thereby improving the reliability of power or signal transmission, and The second contact portion 24 abuts the plug electrical connector 5 with the bent portion 241.

The specific embodiments set forth in the detailed description of the preferred embodiments are merely illustrative. The technical content of this creation is not intended to limit the scope of the creation to the examples. All changes made in accordance with the spirit of this creation and the scope of the following patent application are within the scope of this creation.
