Description

A puncture-type connector that is easy to plug and unplug and resistant to vibration Technical Field

[0001] The utility model relates to the field of connectors, in particular to a puncture-type connector that is easy to plug and unplug and is resistant to vibration. Background Art

[0002] Similar connectors currently commonly used on the market have a relatively large insertion and removal force in order to better contact with the PCB board, which makes them difficult to insert and remove. That is, in order to ensure the fit between the terminal and the PCB board, the clamping force of the terminal is relatively large.

[0003] Since the existing mature product structure is limited (ie, the connector needs to be installed at a predetermined position on the product), it is difficult to make improvements on the existing structure.

[0004] To solve this problem, more subtle structural improvements were made within the limited space of the product. By hollowing out the corresponding ribs of the socket that clamp the PCB board, the insertion and removal force can be significantly reduced while still ensuring that the PCB board is clamped. This is more economical and practical, and better meets market demand.

[0006] The main purpose of the utility model is to provide a puncture-type connector that is easy to plug and unplug and resistant to vibration, aiming to solve the above technical problems.

[0007] To achieve the above objectives, the present invention provides a puncture-type connector that is easy to plug and unplug and resistant to vibration, comprising:

[0008] A rear gland, wherein the rear gland is provided with a vertically arranged wire groove;

[0009] The plastic body is detachably mounted on the front end of the rear gland. A through hole matching the wire slot is provided in the direction where the plastic body matches the rear gland. A plurality of terminals are spaced apart between the rear gland and the plastic body.

[0010] The front end of the plastic body is provided with a clamping area, and the clamping area includes an elastic clamping portion and a clamping groove;

[0011] The PCB board includes a board body and a gold finger that matches the terminal. The part of the board body away from the gold finger is in contact with and abuts against the elastic clamping part. The terminal is located at the position of the clamping groove and is in contact with the gold finger.

[0012] In the design of the technical solution of the utility model, the position limitation and installation of the terminal are achieved through the cooperation between the rear pressure cover and the plastic body. At the same time, an elastic clamping part and a clamping groove are provided in the clamping area of ​​the front end of the plastic body, so that the elastic clamping part elastically clamps and fixes the PCB board, and the clamping groove limits the rear end of the terminal to achieve elastic resistance between the terminal and the gold finger part of the PCB board, thereby achieving double clamping and fixation of the PCB board, ensuring both stable contact between the terminal and the PCB gold finger and stable clamping of the PCB board.

[0023] As shown in Figures 1 to 6, an easy-to-plug and vibration-resistant puncture connector includes:

[0024] A rear gland 1 is provided with a vertically arranged wire groove 11;

[0025] The plastic body 2 is detachably mounted on the front end of the rear gland 1. A through hole 21 is provided in the direction where the plastic body 2 and the rear gland 1 match, and a plurality of terminals 3 are provided between the rear gland 1 and the plastic body 2.

[0026] The front end of the plastic body 2 is provided with a clamping area, and the clamping area 4 includes an elastic clamping portion 41 and a clamping groove 42;

[0027] The PCB board 5 includes a board body and a gold finger 52 that matches the terminal 3. The part of the board body away from the gold finger 52 is in contact with and abuts against the elastic clamping portion 41. The terminal 3 is located at the position of the clamping groove 42 and is in contact with the gold finger 52.

[0028] In the design, the terminal 3 is limited and installed by cooperating with the rear pressure cover 1 and the plastic body 2. At the same time, an elastic clamping portion 41 and a clamping groove 42 are provided in the clamping area 4 at the front end of the plastic body 2, so that the PCB board 5 is elastically clamped and fixed by the elastic clamping portion 41, and the rear end of the terminal 3 is limited by the clamping groove 42 to achieve elastic offset between the terminal 3 and the gold finger 52 of the PCB board 5, thereby achieving double clamping and fixation of the PCB board 5, ensuring both stable contact between the terminal 3 and the gold finger 52 of the PCB, and stable clamping of the PCB board 5.

[0029] Specifically, the terminal 3 includes a puncture portion 31 and an elastic clamping arm 32. The puncture portion 31 and the elastic clamping arm 32 are respectively provided with two and are symmetrically arranged along the X-axis. The puncture portion 31 is located at the position of the wire groove 11, and the elastic clamping arm 32 is arranged at the position of the clamping groove 42; the puncture portion 31 is composed of two strip-shaped portions symmetrically arranged along the Y-axis, and the open ends of the two strip-shaped portions are wedge-shaped, that is, through the wedge-shaped opening, when the wire is riveted with the opening, the wire skin is pierced through this structure and contacts with the metal conductor of the wire body, thereby achieving conductivity.

[0030] In the embodiment of the present invention, the portion where the elastic clamping arm 32 fits with the gold finger 52 is provided with a bent end portion, and the bent end portion is provided with a convex bump 321, so that the PCB board 5 and the terminal 3 are in closer contact and also play a role of elastic clamping and fixing.

[0031] Specifically, the elastic clamping portion 41 is bent and extended from the front end of the plastic body 2, and an avoidance groove 6 is provided between the elastic clamping portion 41 and the plastic body 2. Therefore, when the elastic clamping portion 41 is squeezed by the PCB board 5, pressure will be applied toward the avoidance groove 6 and deformation will occur; while significantly reducing the insertion and extraction force, it can also ensure that the PCB board 5 is clamped.

[0032] In the embodiment of the present invention, the elastic clamping parts 41 are symmetrically arranged, and the front ends of the elastic clamping parts 41 are provided with arc chamfers, thereby reducing scratches on the PCB board 5 .

[0033] Furthermore, the PCB board 5 is provided with a limiting groove 71, and the clamping area 4 is provided with a limiting portion 72 that cooperates with the limiting groove 71. The cooperation between the limiting groove 71 and the limiting portion 72 realizes the limitation of the PCB board 5 in the X-axis direction, thereby improving the clamping stability of the PCB board 5; at the same time, it plays an anti-mistake effect in the insertion of the PCB board 5.

[0034] In an embodiment of the present utility model, guide grooves are provided on both sides of the rear pressure cover 1, and the plastic body 2 is provided with a guide portion 81 that cooperates with the guide groove. The guide groove 82 is set to gradually reduce in diameter from the inside to the outside, that is, the upper and lower ends of the guide groove are inclined surfaces, thereby achieving the anti-foolproof and guide locking functions; at the same time, it also plays an anti-foolproof role.

[0035] Furthermore, a slot 91 is provided on one side wall of the plastic body 2 located in the clamping area 4, and a through slot 92 is provided at a position where the PCB board 5 cooperates with the corresponding hole of the PCB board 5 to prevent fooling, and the slot can reduce the PCB insertion force.

[0036] In the embodiment of the present invention, the upper wall of the clamping area 4 of the plastic body 2 is provided with a plurality of upwardly protruding anti-mock ribs 101 at intervals, which play an anti-mock role when the male and female connectors are plugged into each other.

[0037] Furthermore, an upwardly protruding extension column 102 is provided at the rear end of the plastic body 2. When the extension column is pressed, upward pressure can be applied to the front end of the clamping area 4, thereby facilitating the removal of the PCB board 5 and reducing the extraction force.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the practical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
