Description

In addition, in some cases, as shown in Figure 4 , there is still a distance between the power pins 200 and the signal pins 300 and the PCB board 400, so that the connector cannot be normally used for connection. To solve this problem, the conventional method is to lengthen the power pins 200 and the signal pins 300, but this will make the power pins 200 and the signal pins 300 too long, further increasing the installation difficulty.

DETAILED DESCRIPTION

[0056] In order to facilitate the normal connection of the device end socket and the PCB board, the basic technical concept of the utility model is to provide a combined socket which is combined by two independent parts, one part is used for connecting the device, namely the device end socket, and the other part is used for connecting the device end socket and the PCB board, namely the PCB end socket, which is equivalent to an adapter, the PCB end socket comprises signal contact components and power contact components, and the PCB end socket can be connected with the PCB board in advance when assembling. In this way, the power pins and the signal pins of the device end socket do not need to be set too long to realize the normal connection of the device end socket and the PCB board, the device end socket is convenient to directly pass through the through hole of the mounting plate, and the risk of damage of the power pins and the signal pins caused by the contact with the mounting plate is greatly reduced. The utility model will be further described in detail in combination with the embodiments.

[0057] The specific embodiment of the combined socket provided by the utility model is as follows:

[0058] As a most basic embodiment, the connector assembly provided by the embodiment as a whole is shown in Figure 6 , which comprises a device end socket and a PCB end socket (equivalent to an adapter). The device end socket comprises a shell 100 and power pins 200 and signal pins 300 mounted on the shell 100, as shown in Figures 15-18 . In use, the shell 100 can be fixed on the mounting plate 500, and the power pins 200 and the signal pins 300 can pass through the through hole of the mounting plate 500. The basic structure of the PCB end socket is shown in Figure 7 , which comprises an insulator 1, and the insulator 1 is provided with signal contact components 3 and power contact components 2. The insulator 1 is mainly used as the basis for mounting the signal contact components 3 and the power contact components 2, and insulation is the basic requirement. The signal contact components 3 and the power contact components 2 are both provided with PCB connecting ends for electrically connecting with the PCB board 400 and device socket connecting ends for electrically connecting with the device end socket. As shown in Figure 17 , when the parts are assembled to connect the device end socket and the PCB board 400, the PCB end socket can be connected with the PCB through the PCB connecting ends, the power pins 200 and the signal pins 300 in the device end socket can pass through the through hole of the mounting plate 500, the device socket connecting ends of the PCB end socket are connected with the device end socket, and then the normal connection of the device end socket and the PCB board is realized.

[0059] It can be known from the analysis of the above structure that, unlike the prior art Figure 1 , the length of the power pins 200 and the signal pins 300 of the device end socket in the embodiment does not need to be too long, and the device end socket has a straight-through part when being installed, which corresponds to the part located on the right side of the mounting plate 500 in Figure 17 and Figure 18 , and the straight-through part can pass through Figure 17 and Figure 18The shell 100 shown is perpendicular to the mounting plate 500 in the posture of the straight-through mounting plate 500, which is convenient to operate and can greatly reduce the risk of the power pin 200 and the signal pin 300 colliding with the mounting plate 500, thereby solving the problem of the pin being easily damaged. For the case where the PCB board is far away from the through hole on the mounting plate, the existence of the PCB end socket also makes the device end socket can be normally connected with the PCB board, which is convenient to use. Figure 4 The PCB board is far away from the through hole on the mounting plate, and the existence of the PCB end socket also makes the device end socket can be normally connected with the PCB board, which is convenient to use.

[0060] As a more convenient device end socket and PCB end socket connection preferred embodiment, in this embodiment, the device socket connection end of the signal contact part 3 and the power contact part 2 is configured to have a plug-in structure, that is, the signal contact part 3 and the power contact part 2 are both parts including a socket structure. As shown in the figure, Figures 11-13 The signal contact part 3 and the power contact part 2 can both be the tuning fork type shown in the figure, that is, a structure including two elastic arms on both sides to clamp the corresponding pin, and the corresponding plug-in end is the signal plug-in end 34 and the power plug-in end 21 shown in the figure. Of course, the plug-in structure can also be a cylindrical, claw-shaped socket structure.

[0061] In connecting the device end socket and the PCB end socket, as shown in the figure, Figure 17 After the device end socket is installed in place, the whole composed of the PCB board 400 and the PCB end socket is moved to the PCB end socket and the device end socket plug-in installation in the direction shown by the arrow in the figure. Compared with other embodiments using other connection methods (such as welding, pressure connection, bolt connection), this preferred embodiment is obviously more convenient, easy to realize automatic assembly, improve efficiency and reduce labor intensity.

[0062] On the basis of the above preferred embodiment, in order to facilitate the accurate plug-in of the device end socket and the PCB end socket, as a more preferred embodiment, the insulator 1 is provided with a guide structure for guiding cooperation with the device end socket, and the guide structure extends in the direction of the plug-in end and the device end socket plug-in. In this way, the plug-in can be completed while ensuring the state of the device end socket and the PCB end socket.

[0063] Specifically, as a more preferred embodiment of guiding and limiting effect, as shown in the figure, Figure 10 The guide structure on the insulator 1 includes a guide groove 4, and correspondingly, Figure 15 And Figure 17As shown, the device end socket is provided with a guide protrusion 600, and the guide slot 4 can be used for the guide protrusion 600 to enter and move relative to the guide protrusion 600 during the mating process. It is understood that in other embodiments, the positions of the guide slot 4 and the guide protrusion 600 can also be interchanged, that is, the guide structure on the insulator 1 includes a guide protrusion, and correspondingly, the device end socket is provided with a groove (equivalent to a guide slot) at this time, and the guide protrusion is used to enter the corresponding groove and move relative to the groove during the mating process.

[0064] It should be noted here that the guide structure is not limited to the protrusion or slot structure described above. For example, in other embodiments, the opening side wall of the insulator 1 towards the device end socket side can be regarded as a guide structure, and the device end socket can slide along the inner wall surface of the side wall during the mating of the device end socket, which can also play a guiding role in the mating.

[0065] In order to facilitate the manufacture and assembly of the PCB end socket, in some preferred embodiments, the power contact component 2 is configured as an integrated structure and is fixedly mounted on the insulator 1. Specifically, as shown in Figure 11 The power contact component 2 includes a force-fitting portion 23, and the force-fitting portion 23, the PCB connecting end, and the device socket connecting end are an integrated structure, as shown in Figures 8-10 The insulator 1 is provided with a force-fitting slot 5, and the force-fitting portion 23 is inserted into the slot to fix the power contact component 2 relative to the insulator 1. The slot depth direction of the force-fitting slot 5 is along Figure 8 the direction perpendicular to the paper surface, Figure 8 The slot cavity below the force-fitting slot 5 is used for mounting and accommodating the power contact component. The force-fitting here can be understood as a relatively tight fit between the insulator 1 and the force-fitting portion 23, and the relatively large friction between the two can make the insulator 1 and the power contact component 2 relatively fixed. This integrated and directly force-fitted power contact component 2 structure is simpler, and the installation process is also simple, which is more convenient for assembly and production.

[0066] Preferably, in order to make the power contact component 2 and the insulator 1 have a relatively large holding force, as shown in Figure 11 The force-fitting portion 23 is also provided with a barb structure 231, and the force-fitting portion 23 is in interference fit with the force-fitting slot 5 through the barb structure 231. The configuration of the barb structure 231 can make the power contact component 2 and the insulator 1 have a larger holding force and improve stability.

[0067] Similarly, in order to facilitate the manufacture and assembly of the PCB end socket, in some preferred embodiments, the signal contact component 3 is configured as a composite structure including a sheath 31 and a contact conductive piece, which is fixed on the insulator 1 through the sheath 31. Specifically, as shown in Figure 12 and Figure 13As shown, for the case of the signal pin 300 being inserted into the socket, the contact conductor inside the sheath 31 is the signal contact 32. The sheath 31 can serve as a connection, without the need for other adapters. Of course, for the case of not using the signal pin 300 to be inserted into the socket, the contact conductor inside the sheath 31 is the signal contact terminal.

[0068] Specifically, the sheath 31 can be configured with a spring piece 33 (spring wing), and correspondingly, the insulator 1 is provided with a stepped hole. In the state shown in the figure, the sheath 31 is moved upward, and the spring piece 33 is released after entering the larger-diameter part from the smaller-diameter end of the stepped hole, thereby serving as a fixing for the signal contact part 3. The operation is convenient. However, it should be noted that in other embodiments, the sheath 31 and the insulator 1 can also be fixed forcibly. Figure 13

[0069] In order to facilitate the connection of the PCB board 400 and the PCB socket, as a preferred embodiment, as shown in the figure, Figures 11-14 As shown, the PCB connection end of the signal contact part 3 and the power contact part 2 are both welding ends for welding with the PCB board 400, that is, the power welding section and the signal welding end 35 in the figure, respectively. The power welding end 22 and the signal welding end 35 are both sheet-shaped structures that can be inserted into the PCB board 400, and after being inserted into the PCB board 400, the power welding end 22 and the signal welding end 35 can be conveniently and efficiently welded. In other embodiments, if the signal contact part 3 and the power contact part 2 are both circular structures, the power welding end 22 and the signal welding end 35 are both columnar structures that can be inserted into the PCB board 400.

[0070] In order to facilitate the manufacture of the equipment socket, as shown in the figure, Figure 16 The power pin 200 and the signal pin 300 can be integrally inlaid into the shell 100 by using the inlaid pin injection process (prior art). Compared with the scheme of first forming the shell 100 and then separately installing the power pin 200 and the signal pin 300, this can be efficiently manufactured.

[0071] It should be noted that the signal contact part 3 and the power contact part 2 shown in the figure are both straight structures, for example, Figure 11 The line connecting the power welding end 22, the power plug-in end 21, and the center of the power contact part 2 is parallel (180°), but in other embodiments, according to the actual installation conditions, the power welding end 22 and the power plug-in end 21 can also be configured as a curved structure at a set angle.

[0072] Specific embodiments of the adapter in the utility model:

[0073] The embodiment of the adapter is the PCB socket described in the embodiment of the above-mentioned combined socket, which will not be described in detail here. ​

[0074] Specific embodiments of the connector assembly in this utility model:

[0075] The connector assembly includes a device-side socket and an adapter as described in the adapter embodiment above. The device-side socket can be consistent with existing technology, i.e., it includes a housing and power pins and signal pins disposed on the housing. It should be noted that the lengths of the power pins and signal pins of the device-side socket in this embodiment may not necessarily meet the requirements for through-holes on the mounting plate. However, due to the presence of the adapter, for applications such as... Figure 4 The situation shown, where a normal connection to the PCB board is difficult, can be resolved using an adapter without extending the power and signal pins. This solution is actually more convenient than extending the power and signal pins.

[0076] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features.
