Description

Electrical connector with tongue reinforcement structure

technical field

The present invention is an electrical connector, especially an electrical connector with a tongue reinforcing structure to prevent damage due to improper operation when plugging with a connector.

Background technique

A known USB TYPE C electrical connector is shown in FIG. 8 , which mainly includes a package body 80 in a metal shield 70 . The specific structure of the package body 80 is shown in FIGS. 9 and 10 . A tongue piece 81 is formed on the front end surface extending outward in a horizontal direction. The package body 80 and the tongue piece 81 are provided with a plurality of upper-layer terminals 91 and a plurality of lower-layer terminals 92, and one end of each upper-layer terminal 91 and each lower-layer terminal 92 is respectively Partially exposed on the upper and lower surfaces of the tongue piece 81 for electrical contact.

Furthermore, a spacer 60 is provided inside the package body 80 and its tongue 81 . As shown in FIG. 10 , the spacer 60 is located between the upper-layer terminals 91 and the lower-layer terminals 92 . Sheet-like, with a wide section 61 and a narrow section 62, the narrow section 62 is suitable for being located in the tongue 81 of the package body 80, and the adjacent ends of the narrow section 62 and the wide section 61 extend forward from both sides to form two side wings 63 respectively. , the two side wings 63 are partially exposed on both sides of the tongue piece 81 respectively, so as to form protection for both sides of the tongue piece 81 .

According to the specifications set by USB TYPE C, it must have more than 10,000 times of insertion and extraction tolerance, and must also pass the 4-axis test. However, the size of the USB TYPE C interface is only 8.3 × 2.5 mm, and the 81 tongues are more It is only 0.7 mm, but it is the place where the 4 axial forces are most concentrated. In addition to the function of isolating the upper terminal 91 and the lower terminal 92, the side wings 62 of the spacer 60 are also used to reinforce the two sides of the tongue 81. However, it is known that the spacer 60 of the USB TYPE C electrical connector is mostly formed by stamping metal thin materials, and is used as a side wing 63 for reinforcing protection. Only one end is connected to both sides of the spacer 60 in a small area. It is located on both sides of the septum 60 after being folded, so the wear resistance on both sides of the lifting tongue 81 is very limited, which causes the tongue 81 to be easily damaged after frequent plugging and unplugging, thereby affecting the normal operation.

Furthermore, because the tongue 81 of the USB TYPE C electrical connector is extremely thin, when the user connects with the corresponding connector, if the deviation of the insertion angle is too large or the force is improperly applied, the tongue 81 may be directly damaged and the normal use may be affected. . From the above, it can be seen that the strength of the tongue of the existing USB TYPE C electrical connector needs to be strengthened, so that it is easy to be damaged due to improper operation during unplugging and plugging. Therefore, it needs to be further reviewed and a feasible solution is sought.

SUMMARY OF THE INVENTION

Therefore, the main purpose of the present invention is to provide an electrical connector with a tongue reinforcement structure, which can comprehensively reinforce the tongues in multiple axial directions, so as to greatly improve the insertion and extraction tolerance.

The main technical means adopted to achieve the aforementioned purpose are to make the aforementioned electrical connector with a tongue reinforced structure include:

a package body, which extends outward on a front end surface to form a tongue;

an upper-layer terminal group located in the package body, the upper-layer terminal group is composed of a plurality of upper-layer terminals, and one end of each upper-layer terminal is partially exposed on the upper surface of the tongue;

a lower-layer terminal group, located in the package body, the lower-layer terminal group is composed of a plurality of lower-layer terminals, and one end of each lower-layer terminal is partially exposed on the lower surface of the tongue;

A spacer is arranged in the package body and its tongue, and is interposed between the upper and lower terminal groups. Two tongue sides and a tongue tip of the tongue piece are formed.

The present invention mainly extends longitudinally on both sides and the front side of the spacer to form a protective wall, which is different from the structure of the known electrical connector in which the spacer is only formed by bending metal sheets to form side wings. The two sides and the front side of the septum form a continuous and thick retaining wall respectively, and form the tongue side and the tongue tip of the tongue piece respectively, so that the tongue piece can be comprehensively reinforced in a multi-axial manner, in addition to greatly improving the tongue piece In addition to the wear-resistant characteristics of insertion and extraction, since the tongue piece of the present invention has a high-strength tongue tip, when the tongue piece is inserted into the connector, even if the connector directly hits the tongue piece and/or its tongue tip due to the deviation of the insertion angle or excessive force, All can effectively ensure that the tongue is not damaged and maintain normal work.
