Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a 22P reverse plug-in connector. Background Technology

[0002] Pin headers are devices consisting of insulated metal pins arranged at specific intervals with various plastic frames, used for signal and power transmission between boards or different modules. These connectors are widely used in PCBs (Printed Circuit Boards) in electronics, electrical appliances, and instrumentation. Their function is to act as a bridge between blocked or isolated circuits, facilitating current or signal transmission. They are typically used with female headers to form board-to-board connections; or with electronic wire harness terminals to form board-to-wire connections; or they can be used independently for board-to-board connections.

[0003] An existing pin header connector includes a connector body and several pin header groups. The connector body has pin holes for inserting the pin headers. The pin header groups are inserted and fixed in the pin holes. One end of each pin extends into the connector body and the other end extends out of the connector body. This type of pin header connector has several drawbacks. Due to the inconsistent height of the contact parts between the pin header groups, uneven force can easily lead to poor contact during insertion and removal, affecting the stability of signal transmission. Furthermore, the pin headers are prone to loosening during use, affecting the normal operation of the pin header connector.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a 22P reverse plug-in connector. Through the design of the raised part and groove on the upper end face of the insulating body, the connection part of the first terminal group is adapted to the raised part, so that the contact parts of the first and second terminal groups are flush. During plugging and unplugging, each contact part is subjected to force synchronously, avoiding poor contact caused by height difference and ensuring stable signal and power transmission.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A 22P reverse-push-out connector includes an insulating body, a first terminal group, and a second terminal group. The insulating body has a first terminal hole group and a second terminal hole group spaced apart along its length. Each of the first and second terminal groups includes a plurality of terminals, and each terminal includes an integrally formed contact portion, a connecting portion, and a soldering portion.

[0008] The upper end face of the insulating body is recessed with a receiving cavity. The left and right sides of the receiving cavity are respectively provided with raised parts extending upwards corresponding to the first terminal hole group. Adjacent raised parts are provided with grooves. The first terminal group and the second terminal group are inserted and pulled into the insulating body from bottom to top. The connecting part of the first terminal group is located on the raised part, so that the contact part of the first terminal group is flush with the contact part of the second terminal group.

[0009] The rear side of the insulating body also extends downwards with a positioning part for subsequent plug-in and plug-in connection with external products, and the positioning part extends beyond the lower end of each welded part.

[0010] The connecting part is provided with a limiting part that prevents the terminal from becoming loose when it is inserted into the insulating body. Correspondingly, the insulating body is provided with a limiting groove that matches the limiting part. The terminal is inserted into the insulating body from bottom to top, so that the limiting part is confined within the limiting groove.

[0011] As a preferred embodiment, the limiting portion includes a first limiting protrusion, a second limiting protrusion, and a third limiting protrusion arranged sequentially from top to bottom. The limiting groove includes a first limiting groove, a second limiting groove, and a third limiting groove arranged sequentially from top to bottom. The first limiting protrusion, the second limiting protrusion, and the third limiting protrusion are arranged in a gradually increasing order with the first limiting groove, the second limiting groove, and the third limiting groove. When several terminals are inserted and removed from the insulating body from bottom to top, the first limiting protrusion, the second limiting protrusion, and the third limiting protrusion are respectively adapted to the first limiting groove, the second limiting groove, and the third limiting groove.

[0012] As a preferred embodiment, the positioning part is further recessed with a docking groove, which is used to cooperate with the docking part of an external product.

[0013] As a preferred embodiment, a mis-proof part is further recessed at the location corresponding to the positioning part within the accommodating cavity.

[0014] As a preferred embodiment, the raised portion divides the accommodating cavity into a first mounting area and a second mounting area. The first terminal group and the second terminal group are disposed in the first mounting area and are at least partially arranged in parallel with the first terminal group; the second terminal group is disposed in the second mounting area.

[0015] As a preferred embodiment, a reinforcing member is further extended upward from the front end of the insulating body. The reinforcing member includes an extension portion and a support portion. The extension portion extends upward from the front end of the insulating body, and the support portion is connected to the rear end of the extension portion and the upper end face of the insulating body, respectively, to provide support and prevent the terminals from bending / displaced due to insertion / removal force or vibration.

[0016] As a preferred embodiment, the lower end of the insulating body is further provided with a vertical reinforcing part to enhance the structural strength of the insulating body and prevent the body from deforming or cracking under conditions such as insertion / removal and vibration.

[0017] As a preferred embodiment, the front end of the insulating body is further provided with a snap-fit ​​portion that cooperates with the external structure to achieve mechanical locking of the connector, prevent loosening due to vibration or pulling during use, and ensure connection reliability.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the design of the raised part and groove on the upper end face of the insulating body to make the connecting part of the first terminal group fit the raised part, so that the contact parts of the first and second terminal groups are flush. When inserting or removing, each contact part is subjected to force synchronously, avoiding poor contact caused by height difference and ensuring stable signal and power transmission.

[0019] Secondly, the design of the limiting part and the limiting groove ensures that when the terminal is inserted from bottom to top, the limiting part is embedded in the limiting groove to form a mechanical limiting structure, which can effectively prevent the terminal from becoming loose during use.

[0020] The positioning section, extending beyond the lower end of the solder joint, extends from the rear of the insulating body, providing a precise positioning reference for the insertion and removal of external products. This facilitates quick alignment and improves the efficiency of reverse insertion and removal assembly. Simultaneously, the positioning section can adapt to the installation requirements of different external products, enhancing the connector's versatility and meeting the needs of compact electronic devices and diverse connection scenarios.

[0045] A 22P reverse pluggable connector includes an insulating body 1, a first terminal group 2, and a second terminal group 3.

[0046] The insulating body 1 has a first terminal hole group and a second terminal hole group spaced along its length. The upper end surface of the insulating body 1 is recessed with a receiving cavity 11. The left and right sides of the receiving cavity 11 are respectively provided with raised portions 12 extending upwards corresponding to the first terminal hole groups. Adjacent raised portions 12 are spaced apart by grooves 13. The first terminal group 2 and the second terminal group 3 are inserted and pulled into the insulating body 1 from bottom to top. The connecting portion 212 of the first terminal group 2 is located on the raised portion 12, so that the contact portion 211 of the first terminal group 2 is flush with the contact portion 211 of the second terminal group 3.

[0047] Preferably, the raised portion 12 divides the accommodating cavity 11 into a first mounting area and a second mounting area, the first terminal group 2 and the second terminal group 3 are disposed in the first mounting area and are at least partially disposed in parallel with the first terminal group 2; the second terminal group 3 is disposed in the second mounting area.

[0048] The insulating body 1 extends downward from its rear side to a positioning part 14 for subsequent plug-in connection and positioning with external products. The positioning part 14 extends beyond the lower end of each welding part 213. Preferably, the positioning part 14 is also recessed with a mating groove 141, which is used to cooperate with the mating part of the external product.

[0049] Correspondingly, the insulating body 1 is provided with a limiting groove 15 that matches the limiting part. The terminal is inserted into the insulating body 1 from bottom to top, so that the limiting part is confined within the limiting groove 15. In this embodiment, when the first terminal group 2 and the second terminal group 3 are inserted and removed from the insulating body 1, they are both straight terminals. After the first terminal group 2 and the second terminal group 3 are inserted and removed from bottom to top, they are bent by a tooling fixture. The reverse insertion and removal design of the first terminal group 2 and the second terminal group 3 means that the contact part 211 of each terminal is first passed through the bottom of the insulating body 1. Since the depth of the third limiting groove 153 is greater than the size of the first limiting part and the second limiting part, there will be no interference during the installation process, which will affect the assembly.

[0050] The limiting groove 15 includes a first limiting groove 151, a second limiting groove 152 and a third limiting groove 153 arranged sequentially from top to bottom. The first limiting protrusion 2121, the second limiting protrusion 2122 and the third limiting protrusion 2123 are arranged in a gradual manner from small to large with the first limiting groove 151, the second limiting groove and the third limiting groove 153.

[0051] Preferably, a reinforcing member 16 extends upward from the front end of the insulating body 1. The reinforcing member 16 includes an extension portion 161 and a support portion 162. The extension portion 161 extends upward from the front end of the insulating body 1, and the support portion 162 is connected to the rear end of the extension portion 161 and the upper end face of the insulating body 1, respectively, to provide support and prevent the terminals from bending / displaced due to insertion / extraction force or vibration.

[0052] Preferably, a mis-proof part 17 is recessed in the cavity 11 corresponding to the positioning part 14. Preferably, a vertical reinforcing part 18 is extended from the lower end of the insulating body 1 to enhance the structural strength of the insulating body 1, preventing deformation and cracking of the body under conditions such as insertion / removal and vibration.

[0053] Preferably, the front end of the insulating body 1 is further provided with a snap-fit ​​part 19 that cooperates with the external structure (the slot of the shielding shell) to achieve mechanical locking of the connector, prevent loosening due to vibration or pulling during use, and ensure connection reliability.

[0054] The first terminal group 2 and the second terminal group 3 each include a plurality of terminals 21, and each plurality of terminals 21 includes an integrally formed contact portion 211, a connecting portion 212 and a soldering portion 213.

[0055] The connecting part 212 is provided with a limiting part to prevent the terminal from becoming loose when it is inserted into the insulating body 1. Preferably, the limiting part includes a first limiting protrusion, a second limiting protrusion 2122 and a third limiting protrusion 2123 arranged sequentially from top to bottom. When several terminals are inserted and pulled into the insulating body 1 from bottom to top, the first limiting protrusion 2121, the second limiting protrusion 2122 and the third limiting protrusion 2123 are respectively adapted to the first limiting groove 151, the second limiting groove 152 and the third limiting groove 153.

[0056] The key design feature of this utility model is that, through the design of the raised part and groove on the upper end face of the insulating body, the connection part of the first terminal group is adapted to the raised part, so that the contact parts of the first and second terminal groups are flush. When inserting or removing, each contact part is subjected to force synchronously, avoiding poor contact caused by height difference and ensuring stable signal and power transmission.

[0057] Secondly, the design of the limiting part and the limiting groove ensures that when the terminal is inserted from bottom to top, the limiting part is embedded in the limiting groove to form a mechanical limiting structure, which can effectively prevent the terminal from becoming loose during use.

[0058] The positioning section, extending beyond the lower end of the solder joint, extends from the rear of the insulating body, providing a precise positioning reference for the insertion and removal of external products. This facilitates quick alignment and improves the efficiency of reverse insertion and removal assembly. Simultaneously, the positioning section can adapt to the installation requirements of different external products, enhancing the connector's versatility and meeting the needs of compact electronic devices and diverse connection scenarios.

[0059] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
