Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a plug-and-pull resistant board-end connector. 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 main design point of the existing male and female connectors is whether the locking is stable after insertion. However, during the insertion process, one parameter also greatly affects the stability of the connector, that is, the insertion of the PIN pin structure. The alignment is the key to whether the PIN pin is damaged and whether the contact is stable. The existing design generally uses a PIN pin with higher hardness to ensure stable contact and consistent insertion between the terminals. However, there is also a problem that the user uses a pressure exceeding the preset value during the insertion process, causing damage to the PIN, affecting the stability of the connector. Utility Model Content

[0004] The main purpose of the utility model is to provide a plug-resistant board-end connector, aiming to improve the matching structure of the male head and the female head, thereby improving the combination stability between the male head and the female head, and the structure is simple and stable.

[0005] To achieve the above purpose, the utility model provides a plug-resistant board-end connector, comprising:

[0006] A female connector, the female connector comprising a female rubber shell and a female groove provided in the female rubber shell, the female groove being provided with at least two PIN pins, and an inner wall of the female groove being provided with a guide strip protruding between the two PIN pins;

[0007] A male connector, the male connector comprising a male plastic shell and a male slot provided with the male plastic shell, the male slot being provided with a female terminal, the outer wall surface of the male connector being provided with a guide slot matched with a guide strip, the guide strip being provided along the length direction of the female slot;

[0008] A locking device that engages with each other is provided between the upper wall of the female rubber shell and the male rubber shell, and the locking device is used to lock the male rubber shell and the female rubber shell with each other when they are plugged together.

[0009] In the actual design, a guide strip is provided on the inner wall of the female rubber shell and a guide groove is provided on the outer wall of the male rubber shell, and the length of the guide strip is greater than the length of the PIN pin. Therefore, when the male rubber shell and the female rubber shell are plugged into each other, the guide groove and the guide strip fit each other until the PIN pin is inserted into the female terminal, thereby ensuring the concentricity of the PIN pin and avoiding bending damage caused by force on the PIN, thereby improving its durability. At the same time, the setting of the guide strip and the guide groove also plays an anti-fool effect, thereby improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figures 1 to 5 As shown, a pluggable board-end connector comprises:

[0027] A female connector 1, the female connector 1 comprising a female rubber shell 10 and a female slot 11 provided in the female rubber shell 10, the female slot 11 being provided with at least two PIN pins 12, and an inner wall of the female slot 11 being provided with a guide strip 31 protruding between the two PIN pins 12;

[0028] The male connector 2 comprises a male plastic shell 20 and a male slot 21 provided with the male plastic shell 20, the male slot 21 is provided with a female terminal 22, and the outer wall surface of the male connector 2 is provided with a guide slot 32 matched with the guide strip 31, and the guide strip 31 is arranged along the length direction of the female slot 11;

[0029] A locking device that engages with each other is provided between the upper wall of the female rubber shell 10 and the male rubber shell 20 , and the locking device is used to lock the male rubber shell 20 and the female rubber shell 10 with each other when they are plugged together.

[0030] In the actual design, a guide strip 31 is provided on the inner wall of the female rubber shell 10 and a guide groove 32 is provided on the outer wall of the male rubber shell 20, and the length of the guide strip 31 is greater than the length of the PIN needle 12. Therefore, when the male rubber shell 20 and the female rubber shell 10 are plugged into each other, the guide groove 32 and the guide strip 31 fit together until the PIN needle 12 is inserted into the female terminal 22, thereby ensuring the concentricity of the PIN needle 12 and avoiding bending damage caused by the force on the PIN, thereby improving its durability. At the same time, the setting of the guide strip 31 and the guide groove 32 also plays a fool-proof role, thereby improving the convenience of use.

[0031] Specifically, the two side walls of the guide bar 31 are vertical walls 33, and a first chamfer 34 is provided between the upper wall and the side wall of the guide bar 31. The chamfer and the vertical wall 33 are used to avoid the alignment problem between the guide bar 31 and the guide groove 32, which facilitates insertion. At the same time, the vertical wall 33 is provided to ensure that the lateral pressure acts between the guide bar 31 and the guide groove 32, reducing the force on the PIN pin 12, and also avoiding the bending of the PIN pin 12 and the female terminal 22 caused by abnormal falling during the insertion process.

[0032] In the embodiment of the utility model, a positioning groove 41 is vertically extended from the rear end of the guide groove 32 , and the guide strip 31 is provided with a positioning strip 42 matched with the positioning groove 41 , thereby realizing multi-layer positioning of the female rubber shell 10 and the male rubber shell 20 .

[0033] Specifically, buckle grooves 51 are provided on both sides of the inner wall of the female groove 11 , and buckle portions 52 matching with the buckle grooves 51 are provided on both side walls of the male rubber shell 20 , thereby achieving mutual locking between the male rubber shell 20 and the female rubber shell 10 .

[0034] In the embodiment of the utility model, a stopper 43 is provided at the rear end of the positioning groove 41 , and the stopper 43 is used to prevent the male rubber shell 20 and the female rubber shell 10 from being over-inserted, resulting in wear of the female terminal 22 .

[0035] Specifically, the locking device includes a buckle 61 provided on the upper wall of the female plastic shell 10 and a buckle plate 6 extending upward from the upper wall of the male plastic shell 20. The front part of the buckle plate 6 is provided with a slot 62 matched with the buckle 61. The buckle plate 6 can drive the slot to swing between the locking position with the buckle 61 and the position away from the buckle 61. In this way, the mutual locking between the male plastic shell 20 and the female plastic shell 10 is realized. When the two are plugged in, the plug-in and pull-out test is performed at a rate of 50±3mm per minute. A relatively stable holding force can be maintained between the terminal and the plastic shell, and there will be no problem of deformation of the PIN needle 12.

[0036] Simultaneously in the X, Y and Z directions at 491 m / s 2 (100g force) was tested, and the PIN needle 12 did not deform.

[0037] The test is performed through multiple constraints of the device, the guide bar 31 and the guide groove 32 and the positioning groove 41 and the positioning bar 42, thereby improving the plugging and unplugging strength between the male rubber shell 20 and the female rubber shell 10.

[0038] In the embodiment of the utility model, a support arm 63 extends downward from the middle of the bottom wall of the buckle plate 6, and a wrench portion 64 is protruded from the rear end of the upper wall of the buckle plate 6. The buckle plate 6 can swing with the support arm 63 as a fulcrum, thereby achieving passive locking between the male rubber shell 20 and the female rubber shell 10.

[0039] Specifically, welding plates 7 are provided on both sides of the front portion of the lower wall of the mother rubber shell 10 .

[0040] In the embodiment of the utility model, the rear end of the PIN pin 12 is bent along the flat surface of the rear wall of the mother plastic shell 10 to extend to form a first bent portion 8, and the first bent portion extends downward from the upper end to the lower end of the mother plastic shell 10 and is bent outward to form a welding foot 81. The integrated welding foot and the welding plate are arranged to facilitate the mutual welding and fixing of the mother plastic shell 10 and the PCB board.

[0041] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
