Description

Technical Field

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

[0002] A connector is also called a plug. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector. The basic performance of a connector can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. The mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and whether the connector can normally complete its connection function (such as the contact resistance value) after the specified number of plugging and unplugging cycles is used as the evaluation basis.

[0003] When the existing connector is welded to an external PCB board, it is directly placed at the corresponding position on the PCB board and then welded. When applied to products with different thicknesses, especially products with a relatively thin thickness, the available installation space is smaller, and it cannot meet the usage requirements of products with a small installation space, resulting in greater limitations in use. It is often necessary to design connectors with different thicknesses for different products, resulting in a higher usage cost of the connectors. Therefore, it is necessary to further improve the structure of the existing connector. Summary of the Utility Model

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide a connector with a counterbore function, which can effectively solve the problems of the existing connector having great limitations in use, being unable to meet the usage requirements of thin and light products, and having a high usage cost.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] A connector with a counterbore function includes an insulating body, a terminal group, and a shielding shell; the terminal group is embedded in the insulating body, the terminal group includes a plurality of terminals, the welding part of each terminal extends backward out of the insulating body, and the welding part of each terminal includes a plurality of welding surfaces arranged in sequence from top to bottom for connecting with an external PCB board; the shielding shell is sleeved on the periphery of the insulating body, and support parts are respectively formed outward on the left and right sides of the shielding shell, each support part includes a plurality of support surfaces arranged in sequence from top to bottom for cooperating with an external PCB board, and the plurality of support surfaces respectively correspond to the heights of the plurality of welding surfaces.

[0007] As a preferred solution, a tongue plate extends forward integrally from the front end of the insulating body, and the front ends of the plurality of terminals are respectively exposed on the upper and lower surfaces of the tongue plate.

[0008] As a preferred solution, the multiple welding surfaces are integrally bent and formed by the welding parts respectively.

[0009] As a preferred solution, there are 3 welding surfaces arranged in sequence from top to bottom, and the height of the welding surfaces decreases successively from front to back. Correspondingly, there are also 3 supporting surfaces arranged in sequence from top to bottom, and the height of the supporting surface close to the shielding case is greater than that of the supporting surface far from the shielding case.

[0010] As a preferred solution, the supporting parts are two groups arranged at intervals in the front-back direction.

[0011] As a preferred solution, the supporting parts are integrally bent and formed by the shielding case.

[0012] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0013] Since the welding part of each terminal includes multiple welding surfaces connected to the external PCB board and arranged in sequence from top to bottom, and each supporting part includes multiple supporting surfaces cooperating with the external PCB board and arranged in sequence from top to bottom, and the multiple supporting surfaces respectively correspond to the heights of the multiple welding surfaces. When installing with the external PCB board, different heights of welding surfaces and supporting surfaces can be selected according to the requirements of the actual installation space, so that the connector can sink into the corresponding depth of the PCB board downward, thereby reducing the height of the connector after installation, making it possible to meet the small-size installation space and be applicable to thin and light products, with less use limitations; at the same time, there is no need to design connectors with different thicknesses, and the use cost is also lower.

[0024] Please refer to Figures 1 to 3 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including an insulating body 10, a terminal group 20 and a shielding case 30.

[0025] The terminal group 20 is embedded on the insulating body 10. The terminal group 20 includes a plurality of terminals 21. The welding part 211 of each terminal 21 extends backward out of the insulating body 10, and the welding part 211 of each terminal 21 includes a plurality of welding surfaces 212 arranged in sequence from top to bottom for connecting with an external PCB board. In this embodiment, a tongue plate 11 extends integrally forward from the front end of the insulating body 10, and the front ends of the plurality of terminals 21 are respectively exposed on the upper and lower surfaces of the tongue plate 11 so as to be in contact conduction with an external connector. The plurality of welding surfaces 211 are respectively formed by integrally bending the welding part 21, and the forming method is simpler. The welding surfaces 212 are 3 arranged in sequence from top to bottom, and the height of the welding surface 212 decreases sequentially from front to back. Similarly, the welding surface 212 can also be set with other numbers, so as to meet the installation requirements of more heights, not limited thereto.

[0026] The shielding case 30 is sleeved on the periphery of the insulating body 10. On the left and right sides of the shielding case 30, support portions 31 are respectively formed outward. The support portions 31 are used to support the whole connector during installation, so as to ensure the structural stability of the connection between the connector and the external installation. Each support portion 31 includes a plurality of support surfaces 311 arranged in sequence from top to bottom and cooperating with the external PCB board, and the heights of the plurality of support surfaces 311 respectively correspond to the heights of the plurality of welding surfaces 212. Through the corresponding cooperation of the support surfaces 311 with different heights and the welding surfaces 212 with different heights, the connector can be welded to the external PCB board through different welding surfaces 212, so as to control the height of the connector after being installed on the PCB board, and at the same time, the support surfaces 311 with different heights cooperate to support the connector. In this embodiment, the support surfaces 311 are also 3 arranged in sequence from top to bottom, and the height of the support surface 311 close to the shielding case 30 is greater than the height of the support surface 311 far from the shielding case 30. Similarly, the number of the support surfaces 311 can also be other numbers corresponding to the welding surfaces 212, which is not limited thereto. The support portions 31 are two groups arranged at intervals in the front and rear directions. The arrangement of the two groups of support portions 31 can prevent the connector from shaking in the front and rear directions after installation, and further ensure the structural stability of the connection with the external PCB board. The support portions 31 are integrally bent and formed from the shielding case 30, and the overall forming method is simpler. In other embodiments, the support portions 31 can also be bent externally and then welded to the shielding case 30, so that there is no need to design a new cutting die for the shielding case 30.

[0027] The design focus of the present utility model lies in that: the welding portion of each terminal includes a plurality of welding surfaces arranged in sequence from top to bottom and connected to the external PCB board, and each support portion includes a plurality of support surfaces arranged in sequence from top to bottom and cooperating with the external PCB board, and the heights of the plurality of support surfaces respectively correspond to the heights of the plurality of welding surfaces. When installing with the external PCB board, different heights of welding surfaces and support surfaces can be selected according to the actual installation space requirements, so that the connector can sink into the corresponding depth of the PCB board, thereby reducing the height of the connector after installation, making it possible to meet the small-size installation space and be applicable to thin and light products, with less use limitations; at the same time, there is no need to design connectors with different thicknesses, and the use cost is also lower.

[0028] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
