Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a double-headed fisheye pin header connector. Background Art

[0002] The connector is an important component used to connect various electrical components in the vehicle. The contact, as the core part of the connector, realizes the connection between two electronic devices. Therefore, the reliability of its connection determines the reliability of the vehicle's electrical components.

[0003] Currently, male and female pairs are mostly crimped (welded) on different PCB boards in the market. Male and female connectors are butt-connected to connect two PCB boards. However, the male and female pairs may have problems such as empty soldering, cold soldering and loose soldering during the soldering process of the PCB boards. Therefore, a double-headed fisheye pin header connector is proposed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a double-ended fisheye pin header connector, and the specific technical solution is as follows:

[0005] Double-ended fisheye pin header connector, including:

[0006] Connecting shell;

[0007] A plurality of groups of fisheye terminals are respectively inlaid above and below the connecting shell, wherein the fisheye terminals include a base and an integrally formed connecting portion disposed at both ends of the base, an integrally formed assembly portion is disposed at one end of the connecting portion away from the base, and elastic arms are integrally formed on both sides of the assembly portion, and two groups of the elastic arms constitute fisheye holes, which can shrink and rebound under the action of the elastic arms and are used to connect two groups of PCB boards.

[0008] In the above technical solution, fisheye holes are provided at both ends of the substrate. Two groups of fisheye holes can be used to connect two groups of PCB boards respectively without using male and female pairs, which can effectively avoid the problems of empty soldering, cold soldering and loose soldering caused by welding. When the fisheye holes are inserted into the PCB board, the elastic arm first contracts and enters the PCB board, and then under the action of the elastic arm's own restoring force, the elastic arm can be tightly abutted against the PCB board. The direct connection improves the connection reliability, reduces the number of components, and reduces customer costs. The fisheye hole structure at both ends improves maintainability.

[0009] As an improvement of the above technical solution, an inserting portion is provided at one end of the assembly portion away from the connecting portion, and a width of the inserting portion gradually increases toward the assembly portion.

[0010] As an improvement of the above technical solution, the elastic arm includes a deformation surface and a fixed surface, the spacing between the two groups of the deformation surfaces gradually increases from the plug-in portion to the connecting portion, and the two groups of the fixed surfaces are parallel to each other.

[0011] As an improvement of the above technical solution, multiple groups of placement grooves adapted to the base are provided above and below the connection shell, and connecting grooves are provided on the connection shell and at both ends of the placement grooves, and the connecting grooves are adapted to the connection part.

[0012] As an improvement of the above technical solution, the width of the base is greater than the width of the connecting portion.

[0013] Through the above technical solution, the change in the width of the base and the connecting part can limit the fisheye terminal in the connecting shell 10. During a long period of plugging, the fisheye terminal and the connecting shell 10 can be prevented from loosening, making the connection between the fisheye terminal and the connecting shell 10 more stable.

[0014] Beneficial effects of the utility model:

[0015] Fisheye holes are provided at both ends of the substrate. Two groups of fisheye holes can be used to connect two groups of PCB boards respectively without the need for male and female pairs. This can effectively avoid the problems of empty soldering, cold soldering and loose soldering caused by welding at one end. When the fisheye hole is inserted into the PCB board, the elastic arm first contracts and enters the PCB board. Then, under the action of the elastic arm's own restoring force, the elastic arm can be tightly abutted against the PCB board. Direct connection improves connection reliability, reduces the number of components, and reduces customer costs. The fisheye hole structure at both ends improves maintainability.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Double-ended fisheye pin header connector, including:

[0022] Connecting shell 10;

[0023] A plurality of groups of fisheye terminals are respectively inlaid above and below the connecting shell 10, and the fisheye terminals include a base 20 and an integrally formed connecting portion disposed at both ends of the base 20, and an assembly portion 21 is integrally formed at one end of the connecting portion away from the base 20, and elastic arms 22 are integrally formed on both sides of the assembly portion 21, and two groups of the elastic arms 22 constitute fisheye holes 23, and the two groups of the fisheye holes 23 can shrink and rebound under the action of the elastic arms 22, and are used to connect two groups of PCB boards.

[0024] Fisheye holes 23 are provided at both ends of the base 20. Two groups of fisheye holes 23 can be used to connect two groups of PCB boards respectively without using male and female pairs, which can effectively avoid the problems of empty soldering, cold soldering and loose soldering caused by welding at one end. When the fisheye hole 23 is inserted into the PCB board, the elastic arm 22 first shrinks into the PCB board, and then under the action of the elastic arm's own restoring force, the elastic arm can be tightly abutted against the PCB board. The direct connection improves the connection reliability, reduces the number of components, and reduces customer costs. The fisheye structures at both ends of the connector terminal are directly connected to two PCBs, which improves the maintainability of the connector.

[0025] In one embodiment, a plug-in portion 24 is provided at one end of the assembly portion 21 away from the connecting portion, and the width of the plug-in portion 24 gradually increases towards the assembly portion 21. The plug-in portion 24 can play a guiding role to facilitate insertion into the PCB board and avoid damage to the PCB board during the insertion process.

[0026] In order to improve the reliability and stability of the connector, the elastic arm 22 includes a deformation surface and a fixed surface. The spacing between the two groups of the deformation surfaces gradually increases from the plug-in portion 24 to the connecting portion, and the two groups of the fixed surfaces are parallel to each other. Specifically, by gradually increasing the deformation surface, the smoothness of the insertion into the PCB board is improved, which facilitates the contraction of the elastic arm 22, while the fixed surface can increase the contact area between the elastic arm 22 and the PCB board, which can enhance the conductive performance, reduce the resistance, and improve the reliability of the connection.

[0027] In one embodiment, a plurality of placement grooves 11 adapted to the base 20 are provided above and below the connection shell 10, and connection grooves 12 are provided on the connection shell 10 and at both ends of the placement grooves 11, and the connection grooves 12 are adapted to the connection part, and the width of the base 20 is greater than the width of the connection part. Specifically, by changing the width of the base 20 and the connection part, the fisheye terminal can be confined in the connection shell 10, and during a long period of plugging, loosening between the fisheye terminal and the connection shell 10 can be prevented, so that the connection between the fisheye terminal and the connection shell 10 is more stable.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
