Abstract

The utility model relates to a connector, in particular to an improved structure of an HDMI connector. The improved structure comprises a connector body, the connector body comprises a metal cover casing, an insulating seat arranged in the metal cover casing and a plurality of contact terminals arranged in the insulating seat, a front pin extends from the front end of each contact terminal, and a rear pin bent into an angle of 90 DEG extends from the rear end of each contact terminal; and a plastic baffle plate bent into an angle of 90 DEG and matched with the rear pin is arranged on the outer surface of the rear pin bent into the angle of 90 degrees, the plastic baffle plate is closely matched with the insulating seat, and the metal cover casing is covered on the outer surface of the plastic baffle plate. A convex platform is arranged at the front end of the insulating seat, and the head part of the front pin of the contact terminal is embedded in the convex platform. The structure effectively prevents the contact terminals from being jacked out by the terminal elastic sheets of the HDMI wire rods.

Description

A kind of improvement structure of HDMI connector

[technical field]

The utility model relates to connector, refers in particular to a kind of improvement structure of HDMI connector.

[background technology]

HDMI (high-definition multimedia digital transmission interface) can provide the data transfer bandwidth up to 5Gbps; can transmit the audio signal and the high definition video signal that do not have compression; this kind high frequency connectors need not to transmit advance capable D/A or mould/number conversion at signal; can guarantee that high-quality video-audio signal transmits, and have higher Voice ﹠ Video transmission quality.Along with the continuous development of technology and improving constantly of terminal client requirement, HDMI is applied among TV, the LCD more and more widely.

The HDMI connector need connect signal source by the HDMI wire rod.And the quality of HDMI wire rod on the market is uneven, and the terminal shell fragment of HDMI wire rod directly contacts with HDMI connector contact terminal, hard friction takes place, the destruction of causing contact terminal when often mating with the HDMI connector.

Therefore, need the design new construction that HDMI connector contact terminal is protected, exempt from destruction, improve the compatibility and the reliability of HDMI connector.

[summary of the invention]

Technical problem to be solved in the utility model is to provide a kind of improvement structure of HDMI connector, and protection HDMI contact terminal is in order to avoid the HDMI contact terminal is ejected by the terminal shell fragment of HDMI wire rod.

The utility model solves above-mentioned technical problem by the following technical solutions:

A kind of improvement structure of HDMI connector, include a connector body, described connector body comprises the metal case, be arranged at the insulating base in the metal case and be arranged at a plurality of contact terminals in the described insulating base, described contact terminal front end is extended with preceding pin, and the rear end is extended with the back pin that bending is 90 degree; Described insulating base front end is provided with a protruding platform, and the head of pin is bumped in this protruding platform before the described contact terminal.

As the further improvement of the utility model scheme, the back pin outer surface that described contact terminal bending is 90 degree also is provided with the plastic cement baffle plate that bending with matching is 90 degree, and this plastic cement plate washer and insulating base closely cooperate, and its outer surface is covered with the metal case.

The utility model is to be provided with a protruding platform at the insulating base front end, and the head of pin is bumped in this protruding platform before the contact terminal, directly contacts with the contact terminal head when making the terminal shell fragment insertion of HDMI wire rod, therefore, contact terminal is played a protective role.And as preferred version, the pin outer surface also is combined with a plastic cement baffle plate and edge edge seat closely cooperates behind the contact terminal, has increased the confining force of contact terminal, prevents that further contact terminal from being ejected by the terminal shell fragment of HDMI wire rod.

[description of drawings]

In conjunction with the embodiments the utility model being done one with reference to the accompanying drawings describes in detail.

Fig. 1 is first embodiment cross-sectional view of the utility model.

Fig. 2 A is that first embodiment HDMI wire rod of the utility model inserts back cross-sectional view state one;

Fig. 2 B is that first embodiment HDMI wire rod of the utility model inserts back cross-sectional view state two;

Fig. 2 C is that first embodiment HDMI wire rod of the utility model inserts back cross-sectional view state three;

Fig. 2 D is that first embodiment HDMI wire rod of the utility model inserts back cross-sectional view state four;

Fig. 3 is second embodiment cross-sectional view of the utility model.

[embodiment]

Example one:

See also shown in Figure 1, it is first embodiment cross-sectional view of improvement structure of HDMI connector, include a connector body 10, described connector body 10 comprises metal case 11, be arranged at the insulating base 12 in the metal case 11 and be arranged at a plurality of contact terminals 13 in the described insulating base 12, described contact terminal 13 front ends are extended with preceding pin 131, and the rear end is extended with the back pin 132 that bending is 90 degree; Insulating base 12 front ends are provided with a protruding platform 15, and the head of pin 131 is bumped in this protruding platform 15 before the contact terminal 13.

Please consult Fig. 2 A successively, Fig. 2 B, Fig. 2 C, Fig. 2 D is that HDMI wire rod 20 inserts connector body 10 each state cross-sectional view of back.The terminal shell fragment 21 of HDMI wire rod 20 contacts with protruding platform 15 earlier; Then, continue to slide forward, protruding platform 15 struts the terminal shell fragment 21 of HDMI wire rod 20; The terminal shell fragment 21 of HDMI wire rod 20 continues to slide forward, and the terminal shell fragment 21 of HDMI wire rod 20 directly slides to contact terminal 13 preceding pins 131 from protruding platform 15, does not contact with pin 131 heads before the contact terminal 13; At last, continue before the contact terminal 13 pins 131 to advancing slip until to being inserted into the position.

Can very clearly find out from above each state diagram; when 10 pairs of HDMI wire rod 20 and connector bodies are slotting; the terminal shell fragment 21 of HDMI wire rod 20 does not directly contact with contact terminal 13 preceding pins 131; but strut by the terminal shell fragment 21 of protruding platform 15 with HDMI wire rod 20; therefore; protect HDMI contact terminal 13 effectively, in order to avoid HDMI contact terminal 13 is ejected by the terminal shell fragment 21 of HDMI wire rod.So the utility model embodiment one is a novel designs in fact.

Embodiment two:

See also shown in Figure 3, it is the improvement of on the basis of embodiment one, being done, back pin 132 outer surfaces that described contact terminal bending is 90 degree are provided with the plastic cement baffle plate 14 that bending with matching is 90 degree, and this plastic cement plate washer 14 closely cooperates with insulating base 12, and its outer surface is covered with metal case 11.If there is not the plastic cement baffle plate 14 of contact terminal 13 afterbodys, then the terminal shell fragment 21 of HDMI wire rod 20 ejects contact terminal 13 easily.So the utility model embodiment two is reliable more novel designs in fact.
