[0032] The openings of the slots 31 are provided with chamfers, which are more conducive to plugging and use.

[0033] The most improved structure of the present invention is: the housing 3 is integrally fixed on the panel 5 and forms an inseparable structure with the panel 5; the PCBA board 4 is arranged in the housing 6, and the panel 5 is snap-fastened at the port 61 of the housing 6, and the counter slot 31 of the housing 3 is exposed outside the panel 5. That is to say, the present invention fixes the housing 3 constituting the connector to the panel 5 as a whole, that is, the housing 3 is an inseparable part of the panel 5, so that in the later assembly, after welding one end of the pin header 2 to the PCBA board 4, the PCBA board 4 is installed in the housing 6, and finally the panel 5 is snap-fastened to the port 61 of the housing 6 to complete the assembly, wherein the other end of the pin header 2 passes through the panel 5 and extends into the counter slot 31 of the housing 3, so as to be plugged and connected with the mating connector later, so that the panel 5 has at least one connector. The present invention has fewer assembly steps with the panel and the housing, and there is no need to consider the assembly structure of the housing and the panel 5, so it is easier to assemble and the production efficiency is greatly improved. That is to say, the utility model simplifies the connector structure and utilizes the matching mechanism with the housing with the connector (i.e., the panel with its own housing), which simplifies the process steps of the whole machine while ensuring the product function, and can improve the performance of the whole machine, reduce the overall cost, and ensure the lightness of the whole machine. The whole machine refers to the assembly formed by the insulator 1, the pin header 2, the housing 3, the PCBA board 4, the panel 5 and the housing 6. In addition, the assembly process of the pin header is relatively simple, and the existing universal pin header assembly connector can be used for common housing and panel assembly, which greatly reduces the product cost and makes the utility model highly competitive in the market.

[0034] The panel 5 can be integrally injection-molded from plastic, and is very easy to manufacture.

[0035] The assembly structure of the panel 5 and the casing 6 is an inlay buckle fixing structure, specifically: an inlay portion 51 is provided at the rear end of the panel 5, wherein the size of the inlay portion 51 is smaller than the size of the panel 5, and a lock buckle 511 is provided on the inlay portion 51; a lock hole 601 is provided at the port 61 of the casing 6, and the inlay portion 51 is inlaid and installed at the port 61 of the casing 6, and the rear end of the panel 5 contacts the front end surface of the casing 6 to achieve the purpose of inlay installation, and the lock buckle 511 is engaged and locked with the lock hole 601, thereby ensuring that the panel 5 is firmly installed at the front end of the casing 6, and the assembly structure is stable and firm, and the quality can be guaranteed.

Specifically, a plurality of slot bodies 610 are provided at the port 61 of the housing 6, each of which includes two slot bodies 610. The portion of the port 61 of the housing 6 between the two slot bodies 610 is defined as the spring piece 62, and the lock hole 601 is provided on the spring piece 62. When the inlay portion 51 of the panel 5 is inlaid and installed in the port 61 of the housing 6, the lock buckle 511 will first contact the spring piece 62, thereby forcing the spring piece 62 to open outward to form an elastic restoring force, until the lock buckle 511 moves to the lock hole 601, the lock buckle 511 is no longer in contact with the spring piece 62, and the spring piece 62 is reset by the elastic restoring force, so that the lock buckle 511 and the lock hole 601 are snap-locked.

[0037] In order to improve the stability of the assembly structure of the panel 5 and the insulator 1, and to make the pin row pass through the panel 5 and extend into the housing 3 more stably, the following structural improvements are also made: the rear side of the panel 5 is provided with a first positioning column 52, and the front side of the insulator 1 is provided with a first positioning groove 11 adapted to the first positioning column 52, and the first positioning column 52 is embedded in the first positioning groove 11, thereby ensuring that the panel 5 and the insulator 1 are positioned, and the stability of the assembly structure can be improved to a certain extent. Among them, the panel 5 is provided with a terminal hole 501 that passes through the housing 3 along its rear side and forward, and the pin row passes through the terminal hole 501 and extends into the matching slot 31 of the housing 3. Preferably, the end of the first positioning column 52 is also provided with a chamfer, which can enter the first positioning groove 11 more smoothly, thereby improving assembly efficiency and smoothness.

[0038] A plurality of second positioning posts 12 are provided on the lower side of the insulator 1, and a second positioning groove 41 adapted to the second positioning posts 12 is provided on the PCBA board 4. The second positioning posts 12 are embedded in the second positioning groove 41, and the lower side of the insulator 1 is also directly against the surface of the PCBA board 4, so that the insulator 1 is stably installed on the PCBA board 4, and to a certain extent, the pin header 2 can also be stably assembled with the PCBA board 4. In addition, in order to make the assembly of the pin header 2 and the PCBA board 4 more stable, the following design is also made: at least one pin header 2 has two solder feet 201 and a support portion 202 located between the two solder feet 201, and the two solder feet 201 are welded and fixed on the pad 42 of the PCBA board 4, so that the assembly structure is more stable and the conduction performance is better, and the end face of the support portion 202 is in contact with the surface of the PCBA board 4, so as to form a stable support, thereby ensuring that the pin header 2 is more stably installed on the PCBA board 4, thereby improving the product quality.

Among them, the entrance of the guide positioning groove 63 is set as an eight-shaped guide opening, which can play a good guiding role, so that the PCBA board 4 can be more smoothly installed in the guide positioning groove 63, thereby improving the assembly efficiency.

[0040] At least one housing 3 is fixed integrally on the panel 5, and at least one set of pin headers 2 is welded and fixed on the PCBA board 4. After the pin headers 2 are inserted into the housing 3, at least one connector is formed. In this embodiment, the scheme adopted is: two housings 3 are fixed integrally on the panel 5, and two sets of pin headers 2 are welded and fixed on the PCBA board 4. After the pin headers 2 are inserted into the housing 3, two connectors are formed. Of course, the two connectors can be the same connectors or different connectors. They can be designed according to actual use requirements to meet different use requirements.

[0041] The pin header 2 includes at least two signal pin headers 21 and power pin headers 22 with different cross-sectional shapes or cross-sectional areas, and the cross-sectional area of ​​the power pin header 22 is larger than the cross-sectional area of ​​the signal pin header 21. The signal pin header 21 is used to transmit signals, and the power pin header 22 is used to transmit large current or high power. The power pin header 22 is distributed around the insulator 1, and the signal pin header 21 is distributed in the middle of the insulator 1, so as to meet the use requirements of different signals and currents.

[0042] In addition, the pin header 2 also includes a power pin header 23, the cross-sectional area of ​​which is larger than that of the signal pin header 21, and smaller than that of the power pin header 22. The power pin header 23 is used to transmit high power, and is distributed beside the power pin header 22. The utility model adopts the signal pin header 21, the power pin header 22 and the power pin header 23 to form a variety of pin header combinations; pin headers of various sizes are used in combination to cope with different signal and current requirements, which is very convenient to use.

[0043] With the rapid development of new energy vehicles, the integration of various domain controllers, multiple signal controls, and multiple power supply current requirements require connectors to use multiple terminal specifications to meet the needs of application scenarios. The multiple pin header combinations used in this utility model can meet this demand.

[0044] The connector housing and pin header combination of the utility model can be applied to the controller of new energy vehicles, wherein the insulator 1, the pin header 2, the housing 3, the PCBA board 4, the panel 5 and the casing 6 are combined to form the controller of the new energy vehicle.

[0048] In summary, the utility model fixes the shell 3 constituting the connector to the panel 5 as a whole, so that the shell 3 is an inseparable part of the panel 5, so that during the later assembly, after welding one end of the pin header 2 to the PCBA board 4, the PCBA board 4 is then installed in the case 6, and finally the panel 5 is snap-fastened to the port 61 of the case 6 to complete the assembly, wherein the other end of the pin header 2 passes through the panel 5 and extends into the matching slot 31 of the shell 3, so that it can be plugged and connected with the matching connector later, so that the panel 5 has at least one connector. The utility model has fewer assembly steps with the panel and the case, and there is no need to consider the assembly structure problem of the shell and the panel 5, so it is easier to assemble and greatly improves the production efficiency.
