Connector with protective lock catch

Abstract

The connector comprises a shell provided with a lock catch piece, an insulating body, an elastic clamping hook and an elastic clamping hook button, the elastic clamping hook is fixedly connected with the insulating body, the elastic clamping hook button is provided with a lock hole and is integrated with the insulating body, the lock catch piece penetrates through the lock hole, and the lock catch piece penetrates through the lock hole. The movement of the elastic clamping hook key is limited; when the elastic clamping hook key moves in the direction away from the elastic clamping hook, the lock catch piece stops the inner wall of the lock hole, and therefore the elastic clamping hook key stops moving in the direction away from the elastic clamping hook. Compared with the prior art, the elastic clamping hook key can be effectively prevented from excessively moving in the direction away from the elastic clamping hook, so that the elastic clamping hook key is effectively protected, and the damage situations such as bending fracture are avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of electrical connectors, in particular to a connector with a protective lock. Background Art

[0002] like Figure 1 and Figure 2 As shown, a connector includes an insulating body 11 and an elastic hook 12, the insulating body 11 is provided with an elastic hook fixing groove 13 and an elastic hook button 14, the elastic hook 12 is arranged in the elastic hook fixing groove 13, the elastic hook 12 includes a hook claw 121 and a first contact portion 122, and the elastic hook button 14 includes a second contact portion 141 that contacts the first contact portion. Figure 1 and Figure 2 As shown, when the electrical connector is to be unplugged, the elastic hook button 14 is pressed in the direction X1 by hand to make the second contact portion 141 contact the first contact portion 122, thereby driving the hook claw 121 to move in the direction X1, so that the electrical connector can be unplugged.

[0003] However, the reliability of this connector is not high. Specifically, its shortcoming is that when the elastic hook button 14 is displaced too much in the direction away from the elastic hook 12 (i.e., the X2 direction), the elastic hook button 14 bends and breaks, causing damage. Therefore, there is a lack of protective structure to protect the connector. Utility Model Content

[0004] The utility model application proposes a connector with a protective lock to prevent the elastic hook button from excessively moving away from the elastic hook, thereby protecting the connector through the lock and preventing the elastic hook button from bending and breaking.

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

[0006] A connector with a protective lock, comprising:

[0007] The housing is provided with a locking member;

[0008] Insulation body;

[0009] An elastic hook, fixedly connected to the insulating body;

[0010] The elastic hook button is an integrated structure with the insulating body and is provided with a lock hole;

[0011] The locking member passes through the lock hole to restrict the movement of the elastic hook button;

[0012] When the elastic hook button moves in a direction away from the elastic hook, the locking member stops the inner wall of the lock hole, thereby stopping the elastic hook button from moving in a direction away from the elastic hook.

[0013] Preferably, the locking component and the housing are integral.

[0014] Preferably, the housing is a metal shell formed by stamping, and the locking member is a flat arm extending from a side wall of the metal shell.

[0015] Preferably, a buckle hole is provided on the insulating body, and the end of the flat arm is bent and buckled into the buckle hole for fixation.

[0016] Preferably, the cross section of the elastic hook button is T-shaped, including a vertical wall for providing a finger position for pressing and a horizontal wall with a lock hole, and the flat arm passes through the lock hole to form a cross-shaped structure.

[0017] Preferably, the horizontal wall faces away from the elastic hook with a predetermined gap, and when the vertical wall of the elastic hook button is pressed, the horizontal wall pushes the elastic hook to deform and move; when the elastic hook button is displaced a predetermined distance in the direction away from the elastic hook, the inner wall of the lock hole on the horizontal wall away from the vertical wall is restricted and blocked by the flat arm, and at this time, the elastic hook button stops displacing in the direction away from the elastic hook.

[0018] The beneficial effect of the present invention is that the locking member is passed through the lock hole to limit the movement of the elastic hook button, so as to prevent the elastic hook button from being displaced too much in the direction away from the elastic hook. More specifically, when the locking member is set as a metal flat arm and passes through the lock hole to form a cross-shaped limiting protection structure with the limiting part (i.e., the horizontal wall) of the elastic hook button, it can effectively prevent the elastic hook button from moving excessively in the direction away from the elastic hook, thereby effectively preventing the risk of deformation and fracture of the elastic hook button.

[0024] The embodiment of the present application solves the technical problem in the prior art that the elastic hook button bends and breaks when the elastic hook button is displaced too much in the direction away from the elastic hook by providing a connector with a protective lock.

[0025] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problem. The overall idea is to structurally limit and prevent the elastic hook button from being excessively moved and abnormally deformed by having a locking member pass through the lock hole of the elastic hook button.

[0026] The embodiments of the present application are mainly applied to FPC connectors, FFC connectors and low voltage differential signal connectors (abbreviated as LVDS connectors)

[0027] In order to better understand the above technical solution, a preferred specific implementation of the present invention is described in detail below with reference to the accompanying drawings.

[0028] like Figures 3 to 5 As shown in the figures, a connector 00 (also referred to as a plug, hereinafter referred to as a connector) with a protective lock provided by a preferred embodiment of the present invention includes a housing 10, an insulating body 11, an elastic hook 12, and an elastic hook button 13. The housing 10 is fixedly connected to the outside of the insulating body 11, and the elastic hook button 13 and the insulating body 11 are integrated into a structure. The elastic hook 12 is fixedly mounted on both sides of the insulating body 11, and is arranged opposite to the elastic hook button 13 with a predetermined gap. When the elastic hook button 13 is pressed by a finger or a matching tool, the corresponding part of the elastic hook button 13 will passively approach and contact the elastic hook 12, pushing the elastic hook 12 to deform and move, thereby releasing the lock of the matching connection with its counterpart connector (such as a socket, not shown in the figure).

[0029] The connector 00 further includes a plurality of conductive terminals 14 mounted within the insulating body for transmitting signals, the number of which is generally arranged in a row with predetermined equal spacing. Since the innovation of the present invention lies in the locking structure, it will not be described in detail herein.

[0030] In this embodiment, the housing 10 is provided with the locking member 101, and the elastic hook button 13 is provided with a locking hole 131. The locking member 101 passes through the locking hole 131 to restrict the movement of the elastic hook button 13. Specifically, when the elastic hook button 13 moves away from the elastic hook 12, the locking member 101 can stop the inner wall (i.e., the hole wall) of the locking hole 131, thereby stopping the elastic hook button 13 from moving away from the elastic hook 12. This arrangement can effectively prevent the elastic hook button 13 from excessive displacement and deformation, thereby preventing damage or even functional failure when it encounters possible external force. This provides excellent protection for the elastic hook button.

[0031] Specifically, in this embodiment, the latch 101 is integral with the housing 10. The housing 10 is a stamped metal component comprising an upper shielding shell 10a and a lower shielding shell 10b, which can be made of stainless steel or copper alloy. The upper and lower shielding shells 10a and 10b are fixedly connected to the insulating body 11 by covering and securing the upper and lower portions of the housing 11, respectively, providing grounding and shielding for the circuit. The latch 101 extends from a side wall of the metal housing 10 (lower shielding shell) to form a flat arm that bends toward the insulating body. Its distal end snaps into a retaining hole 111 in the insulating body 11, securing it in place. This maintains the latch 101 in a stable, cross-shaped protective structure after passing through the retaining hole.

[0032] The insulating body 11 is a rectangular structure with a roughly "ㄩ" shape formed by an injection molding process, and is made of resin such as LCP and PA. Usually, there are two elastic hook buttons 13, which are located on both sides of the insulating body 11 respectively. Each elastic hook button 13 is a single-ended freely movable long arm extending from a predetermined position on the side of the insulating body 11.

[0033] Furthermore, the cross-section of the elastic hook button 13 is T-shaped, including a vertical wall 13a for providing a finger position for pressing and a horizontal wall 13b with a lock hole 131. The flat arm (i.e., the lock member 101) passes through the lock hole 131 to form a cross-shaped structure.

[0034] Combine Figure 5As shown, the horizontal wall 13b is facing away from the elastic hook 12 with a predetermined gap. When the vertical wall 13a of the elastic hook button 13 is pressed, the horizontal wall 13b pushes the elastic hook 12 to deform and move; when the elastic hook button 13 is displaced a predetermined distance in the direction away from the elastic hook 12, the inner wall of the lock hole 131 on the horizontal wall 13b away from the vertical wall 13a is restricted and blocked by the flat arm 101. At this time, the elastic hook button 13 stops displacing in the direction away from the elastic hook 12, thereby avoiding the elastic hook button 13 from failing due to excessive dragging or scratching.

[0035] To sum up, the utility model effectively limits or prevents the elastic hook button from excessive outward movement due to external force by setting a locking piece and forming a cross-shaped cross protection structure through the lock hole, thereby effectively preventing the risk of deformation and breakage of the elastic hook button.

[0036] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0037] Obviously, those skilled in the art may make various changes and modifications to the present application without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present application fall within the scope of the claims and their equivalents, the present application is intended to include such modifications and variations.
