Description

A puncture connector that is easy to plug and unplug and resistant to vibration

Technical Field

The utility model relates to the field of connectors, in particular to a puncture-type connector which is easy to plug and unplug and resistant to vibration.

Background Art

Similar connectors currently in common use on the market have a relatively large plugging and unplugging force in order to better contact with the PCB board, which causes the problem of being difficult to plug and unplug. That is, in order to ensure the fit between the terminal and the PCB board, the clamping force of the terminal is relatively large.

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

To solve this problem, more subtle structural improvements were made in the limited space of the product. By hollowing out the corresponding ribs of the socket that clamp the PCB board, the plug-in and pull-out force can be significantly reduced after the PCB board is inserted, while also ensuring that the PCB board is clamped. This is more economical and practical, and more in line with market demand.

To achieve the above-mentioned purpose, the utility model provides a puncture-type connector that is easy to plug and unplug and resistant to vibration, comprising:

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

A plastic body, the plastic body can be detachably mounted on the front end of the rear gland, a through hole matching with the wire slot is provided in the direction where the plastic body matches with the rear gland, and a plurality of terminals are arranged between the rear gland and the plastic body.

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;

The PCB board comprises a board body and a gold finger matched with a terminal, the part of the board body away from the gold finger is in contact with and abuts against the elastic clamping part, and the terminal is arranged at the position of the clamping groove and is in contact with the gold finger.

In the design of the technical solution of the utility model, the position limiting and installation of the terminal are realized through the cooperation of the rear pressure cover and the plastic body.

As shown in FIGS. 1 to 6 , an easy-to-plug and vibration-resistant piercing connector comprises:

A rear gland 1, wherein the rear gland 1 is provided with a vertically arranged wire groove 11;

A plastic body 2, the plastic body 2 can be detachably mounted on the front end of the rear gland 1, a through hole 21 matching with the wire slot 11 is provided in the direction where the plastic body 2 matches with the rear gland 1, and a plurality of terminals 3 are arranged between the rear gland 1 and the plastic body 2.

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;

The PCB board 5 includes a board body and a gold finger 52 that matches the terminal 3. The portion 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.

In the design, the terminal 3 is limited and installed by the cooperation of 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 set 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 terminal 3 is limited by the clamping groove 42 to the rear end of the terminal 3 to achieve elastic abutment between the terminal 3 and the gold finger 52 of the PCB board 5, thereby achieving double clamping and fixing of the PCB board 5, which not only ensures the stable contact between the terminal 3 and the gold finger 52 of the PCB, but also ensures the stable clamping of the PCB board 5.

Specifically, the terminal 3 includes a piercing portion 31 and an elastic clamping arm 32. The piercing portion 31 and the elastic clamping arm 32 are respectively provided with two and are symmetrically arranged along the X-axis. The piercing 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 piercing portion 31 is composed of two strip portions symmetrically arranged along the Y-axis, and the open ends of the two strip portions are wedge-shaped, that is, through the wedge-shaped opening, when the wire is riveted to the opening, the wire skin is pierced through this structure to contact the metal conductor of the wire body, thereby achieving conductivity.

In the embodiment of the utility model, the part where the elastic clamping arm 32 fits with the gold finger 52 is provided with a bent end, and the bent end 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.

Specifically, the elastic clamping portion 41 is bent and extended from the front end of the plastic body 2, and an escape 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 escape groove 6 and deformation will occur; while significantly reducing the plug-in and pull-out force, it can also ensure that the PCB board 5 is clamped.

In the embodiment of the utility model, 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 .

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.

In the embodiment of the 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 matching the guide groove. The guide groove 82 is gradually reduced 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.

Furthermore, a groove 91 is provided on one side wall of the plastic body 2 located in the clamping area 4, and a through groove 92 is provided at a matching position of the side wall of the PCB board 5, which can cooperate with the corresponding board hole of the PCB board 5 to prevent fooling, and the groove can reduce the PCB insertion force.

In the embodiment of the utility model, the upper wall of the plastic body 2 located in the clamping area 4 is provided with a plurality of upwardly protruding anti-fool ribs 101 at intervals, that is, they play an anti-fool role when the male connector and the female connector are plugged together.

Furthermore, the rear end of the plastic body 2 is provided with an upwardly protruding extension column 102, and 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.

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.
