Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector with a high-speed novel locking structure. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.

[0003] The existing locking card structure LATCH and the welding plate fixing plate are an integrated structure, which cannot control the requirement that the welding plate feet of the fixing plate remain permanently flat to the board surface, which easily leads to empty welding or cold welding of the welding plate fixing plate; the existing locking card structure LATCH and the welding plate fixing plate are a two-piece structure, but the brake blocking hook on the fixing plate cannot meet the strength requirements of the LATCH when it is fully opened. After locking the card, we must open the LATCH on both sides to the left and right. Since it is opened by manpower, the force will of course be strong or weak. Therefore, when the LATCH is opened to the maximum, if the brake blocking hook is not strong enough, it will easily cause the LATCH to deform or the brake blocking plate on the fixing plate to deform, which will cause the connector to lose its original locking function. Utility Model Content

[0004] The main purpose of the utility model is to provide a connector with a high-speed novel locking structure, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-6 As shown, a high-speed novel locking structure connector in the present scheme comprises an insulating body 1, an upper row of terminals 2 and a lower row of terminals 3, both ends of the connector are provided with locking structures, the locking structure comprises a fixing foot 4 and a locking card 5, the fixing foot 4 is formed by a first holding portion 401 and a second holding portion 402 being integrally formed, a fixing barb 403 is provided at the front end of the first holding portion 401, a surface of the second holding portion 402 is a supporting platform 404, the supporting platform 404 can be used to support the memory card 6, and can prevent the card from being pressed down too much to cause squeezing or crushing of components on the motherboard, one side of the second holding portion 402 is bent upward to form a stopper 405, and the other side of the second holding portion 402 is provided with a fixing plate 406, and the fixing plate 406 can be automatically locked under the action of gravity. The function of the mounting plate is that the front end of the locking card 5 is a locking holding part connected to the insulating body 1, and the end of the locking card 5 is provided with a first clamping part 501 and a second clamping part 502, and a first V-shaped incision 503 is formed between the first clamping part 501 and the second clamping part 502. The design of the first V-shaped incision 503 can avoid interference with the second holding part 402 of the fixing foot 4. A connecting part bending flange 504 is longitudinally provided on the top side of the locking card 5, and a second V-shaped incision 505 is formed between the connecting part bending flange 504 and the first clamping part 501. A supporting limit hook 506 is provided on the bottom side of the locking card 5 to support one side of the fixing foot 4 so that the welding of the fixing foot 4 is always flush with the mounting plate to prevent the locking card 5 (LATCH) from being deformed due to taking out the card when the locking card 5 is opened.

[0024] Specifically, the insulating body 1 has symmetrically disposed receiving portions 11 on both sides, and the receiving portions 11 have receiving grooves 12 disposed therein. The receiving grooves 12 are matched and connected with the fixing legs 4 to facilitate assembly.

[0025] Specifically, the outer side of the lock buckle card 5 is provided with a reinforcing rib 507. The overall strength of the lock buckle card 5 is strengthened, deformation due to stress is effectively prevented, and the problem of fatigue in opening the lock buckle card 5 is solved.

[0026] Specifically, the outer side of the lock retaining portion of the lock buckle card 5 is provided with an anti-retraction hook 508 for matching and connecting with the receiving groove 12. The anti-retraction hook 508 is assembled with the insulating body 1, which is more convenient, and the hook design is more stable and not easy to be separated.

[0027] Specifically, the rear of the lock retaining portion is provided with a wrapping body portion 509, and a U-shaped cutout 510 is provided at the lower side of the wrapping body portion 509. The designed U-shaped cutout 510 can be quickly assembled with the fixing barb 403 of the fixing foot 4, so that the fixing barb 403 on the fixing foot 4 is inserted into the U-shaped cutout 510 to be stable and not shaken.

[0028] Specifically, the front end of the second holding portion 402 is provided with a fixing foot anti-retraction portion 407. The tail of the second holding portion 402 of the fixing foot 4 is bent to form a bent arm, which can prevent the memory card 6 from being ejected during vibration.

[0029] Specifically, the first retaining portion 401 and the second retaining portion 402 are respectively provided with a first convex bump 408 and a second convex bump 409. The first convex bump 408 is punctured on the side of the fixing foot 4 to reduce the movement space of the memory card 6 in a vibration environment; the second convex bump 409 plays a role in strengthening stress and preventing the fixing foot 4 from deforming.

[0030] By adopting the above technical scheme, the working principle and use process of the utility model are as follows: when in use, a support platform 404 is set in the middle position of the fixed foot 4, and a stopper 405 is set on the outer side of the support platform 404. The connection of the stopper 405 is stuck in the middle of the support limit hook 506 on the lock card 5, and effectively prevents the lock card structure from being pulled off from the lock card structure accommodating portion 11 by human beings. The support limit hook 506 at the bottom of the lock card 5 supports the S-shaped connection part of the stopper 405 of the fixed foot 4, so that the welding foot of the fixed foot 4 is always flat against the pasting board, and at the same time prevents the deformation of the lock card 5 caused by human beings taking out the card without opening the lock card 5. The stopper 405 on the fixed foot 4 effectively prevents the lock card 5 structure from being over-opened and causing deformation, and avoids losing the function of the lock card 5. The first clamping part 501 of the lock card 5 is set to an inward-turned hook structure. This inward-turned hook effectively avoids scratching the memory card 6. The fixed foot anti-retraction part 407 can prevent the card from being ejected during vibration.
