Description

Technical Field

[0001] The present invention belongs to the technical field of electrical connectors, and in particular relates to a combined socket, an adapter and a connector assembly. Background Art

[0002] Some parts of the vehicle's electrical and power systems require the use of connectors to connect the PCB (printed circuit board) and related equipment connected to the device end. This connector can be defined as a device-end connector (socket). For example, the patent application with application publication number CN118572414A discloses a high-voltage interlocking connector (socket). The basic structure of this connector is as follows Figure 1 As shown, the power supply unit comprises a housing 100 and a power pin 200 and a signal pin 300 mounted on the housing 100. When in use, Figure 2 and Figure 3 As shown, the housing 100 can be installed on a mounting plate 500 , wherein the mounting plate 500 has reserved through holes for the power pin 200 and the signal pin 300 to pass through. The power pin 200 and the signal pin 300 can be normally connected to the PCB board 400 after passing through the reserved through holes of the mounting plate 500 .

[0003] The power pin 200 and the signal pin 300 of the above-mentioned connector are in a "7" shape as a whole. When installing the connector, it is impossible to directly pass through the through hole reserved in the mounting plate 500. Figure 5 As shown, during installation, the connector needs to be tilted and rotated at a certain angle to ensure that the power pin 200 and the signal pin 300 can pass through the hole smoothly. The installation process is complicated and the operation is inconvenient. Improper operation can easily cause the power pin 200 and the signal pin 300 to collide with the mounting plate 500, causing pin damage. In addition, in some cases, such as Figure 4 As shown, there is still a distance between the power pin 200 and the signal pin 300 and the PCB board 400, so that the connector cannot be used normally. To solve this problem, the conventional method is to extend the length of the power pin 200 and the signal pin 300, but this will make the power pin 200 and the signal pin 300 too long, further increasing the difficulty of installation. Summary of the invention

[0004] The purpose of the present invention is to provide a combined socket to solve the technical problems of inconvenient installation and connection between the device end socket and the PCB board and easy damage to the pins in the prior art. The purpose of the present invention is also to provide an adapter to solve the same technical problem.

[0035] In order to facilitate the normal connection between the device-side socket and the PCB board, the basic technical concept of the present invention is to provide a combined socket composed of two independent parts, one of which is used to connect the device, namely the device-side socket, and the other part is used to connect the device-side socket and the PCB board, namely the PCB-side socket, which is also equivalent to an adapter. The PCB-side socket includes a signal contact component and a power contact component, which can be connected to the PCB board first during assembly. In this way, the normal connection between the device-side socket and the PCB board can be achieved without setting the power pin and the signal pin of the device-side socket to be longer, which facilitates the device-side socket to pass directly through the through hole of the mounting plate, and also greatly reduces the risk of the power pin and the signal pin being damaged by touching the mounting plate. The present invention is further described in detail below in conjunction with the embodiments.

[0036] The specific embodiment of the combined socket provided by the present invention is as follows: As a most basic embodiment, the connector assembly provided in this embodiment is as follows: Figure 6 As shown, it includes a device-side socket and a PCB-side socket (equivalent to an adapter). The device-side socket includes a housing 100 and a power pin 200 and a signal pin 300 mounted on the housing 100. Figure 15-18 As shown, when in use, the housing 100 can be fixed on the mounting plate 500, and the power pin 200 and the signal pin 300 can pass through the through holes on the mounting plate 500. The basic structure of the PCB end socket is as follows Figure 7 As shown, it includes an insulator 1, on which a signal contact component 3 and a power contact component 2 are mounted. The insulator 1 is mainly used as a basis for mounting the signal contact component 3 and the power contact component 2, and insulation is a basic requirement. The signal contact component 3 and the power contact component 2 are both provided with a PCB connection terminal for conductive connection with a PCB board 400 and a device socket connection terminal for conductive connection with a device end socket. Fig.17 As shown, when assembling the various parts so that the device-end socket and the PCB board 400 are connected, the PCB-end socket can first be connected to the PCB through the PCB connecting end, the power pin 200 and the signal pin 300 in the device-end socket can pass through the through hole of the mounting plate 500, and the device socket connecting end of the PCB-end socket is connected to the device-end socket, thereby realizing the normal connection between the device-end socket and the PCB board.

[0037] Analysis of the above structure shows that compared with the prior art ( Figure 1 ) is different in that the length of the power pin 200 and the signal pin 300 of the device-side socket in this embodiment does not need to be too long. During installation, the device-side socket has a straight-through portion, that is, corresponding to Fig.17 and Fig.18 The portion located on the right side of the mounting plate 500 can be Fig.17 and Fig.18 The housing 100 shown is perpendicular to the mounting plate 500 and directly penetrates the through hole of the mounting plate 500, which is easy to operate and can also greatly reduce the risk of the power pin 200 and the signal pin 300 hitting the mounting plate 500, thereby solving the problem of easy damage to the pins. Figure 4 In 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 enables the device-end socket to be normally connected to the PCB board, which is convenient for use.

[0038] As a preferred embodiment that is more convenient for connecting the device-side socket and the PCB-side socket, in this embodiment, the device socket connection end of the signal contact component 3 and the power contact component 2 is configured as a plug-in end with a plug-in structure, that is, the signal contact component 3 and the power contact component 2 are both components including a socket structure. Figure 11-13As shown, the signal contact component 3 and the power contact component 2 can both be the tuning fork type shown in the figure, that is, a structure including elastic arms on both sides to clamp the corresponding pins, and correspondingly, the plug-in ends are 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-type socket structure.

[0039] When connecting the device-side socket and the PCB-side socket, Fig.17 As shown, after the device-side socket is installed in place, the whole composed of the PCB board 400 and the PCB-side socket is moved in the direction indicated by the arrow in the figure until the PCB-side socket and the device-side socket are plugged and installed. Compared with other connection methods (such as welding, crimping, and bolt connection) used in other embodiments, this preferred embodiment is obviously more convenient, easy to realize automated assembly, improve efficiency, and reduce manual labor intensity.

[0040] On the basis of the above preferred embodiments, in order to facilitate accurate plugging of the device-side socket and the PCB-side socket, as a more preferred embodiment, a guide structure for guiding and cooperating with the device-side socket is provided on the insulator 1, and the guide structure extends along the plugging direction of the plugging end and the device-side socket. In this way, the plugging can be completed while ensuring that the device-side socket and the PCB-side socket are aligned.

[0041] Specifically, as an embodiment with better guiding and limiting effects, Fig.10 As shown, the guide structure on the insulator 1 includes a guide groove 4. Fig.15 and Fig.17 As shown, the device-side socket is provided with a guide protrusion 600, and the guide groove 4 is provided for the guide protrusion 600 to enter and to move relative to the guide protrusion 600 during the plugging process. It is not difficult to understand that in other embodiments, the positions of the guide groove 4 and the guide protrusion 600 can also be interchanged, that is, the guide structure on the insulator 1 includes the guide protrusion, and correspondingly, at this time, the device-side socket is provided with a groove (equivalent to the guide groove), and the guide protrusion is used to enter the matching groove and move relative to the groove during the plugging process.

[0042] It should be noted here that, in fact, the guiding structure is not limited to the above-mentioned protrusion or groove structure. For example, in other embodiments, the side wall of the opening of the insulator 1 facing the device-side socket can be regarded as a guiding structure, and when the device-side socket is plugged in, the device-side socket can slide along the inner wall surface of the side wall, which can also play a role in guiding the plugging.

[0043] In order to facilitate the manufacture and assembly of the PCB terminal socket, in some preferred embodiments, the power contact component 2 is configured as an integral structure and is forcibly fixed on the insulator 1. Specifically, as Fig.11As shown, the power contact component 2 includes a strong mounting portion 23, and the strong mounting portion 23, the PCB connection end, and the device socket connection end are an integrated structure, such as Figure 8-Figure 10 As shown, the insulator 1 is provided with a strong installation slot 5, and the strong installation part 23 is inserted into the slot so that the power contact component 2 is fixed relative to the insulator 1. The slot depth direction of the strong installation slot 5 is along Figure 8 In the direction perpendicular to the paper, Figure 8 The slot cavity below the strong mounting slot 5 is used to install and accommodate the power contact component. Strong mounting here can be understood as a tight fit between the insulator 1 and the strong mounting portion 23, and the large friction between the two keeps the insulator 1 and the power contact component 2 relatively fixed. This one-piece directly strong mounting power contact component 2 has a simpler structure, a simpler installation process, and is more convenient for assembly and production.

[0044] Preferably, in order to achieve a greater holding force between the power contact component 2 and the insulator 1, as Fig.11 As shown, the strong mounting portion 23 is also provided with a barb structure 231, and the strong mounting portion 23 is interference fit with the strong mounting slot 5 through the barb structure 231. The barb structure 231 can provide a greater holding force between the power contact component 2 and the insulator 1, thereby improving stability.

[0045] Similarly, to facilitate assembly and manufacture of the PCB terminal socket, in some preferred embodiments, the signal contact component 3 is configured as a composite structure including a sheath 31 and a contact conductive member, which is fixed to the insulator 1 through the sheath 31. Specifically, as Fig.12 and Fig.13 As shown, for this case where the signal pin 300 can be plugged in, the contact conductive member inside the sheath 31 is the signal contact member 32. The sheath 31 can be used for connection without the need for other adapters. Of course, for the case where the signal pin 300 is not connected in this plugging manner, the contact conductive member inside the sheath 31 is the signal contact terminal.

[0046] Specifically, the sheath 31 may be provided with a spring sheet 33 (spring wing), and accordingly, the insulator 1 is provided with a stepped hole inside. Fig.13 In the state shown, the sheath 31 moves upward, and the spring 33 enters the larger part of the stepped hole from the smaller end and can be released, thereby fixing the signal contact component 3, which is convenient for operation. However, it should be noted that in other embodiments, the sheath 31 and the insulator 1 are fixed by force.

[0047] In order to facilitate the connection between the PCB board 400 and the PCB end socket, as a preferred embodiment, as Figure 11-Figure 14As shown, the PCB connection ends of the signal contact component 3 and the power contact component 2 are both welding ends for welding with the PCB board 400, that is, they correspond to the power welding section and the signal welding end 35 in the figure respectively, and the power welding end 22 and the signal welding end 35 are both sheet structures that can be inserted into the PCB board 400. When connected, the power welding end 22 and the signal welding end 35 can be conveniently and efficiently welded after being inserted into the PCB board 400. In other embodiments, if the signal contact component 3 and the power contact component 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.

[0048] To facilitate the manufacture of device-side sockets, such as Fig.16 As shown, the power pin 200 and the signal pin 300 can be integrally embedded into the housing 100 by using a pin-embedding injection process (existing technology). Compared with the solution of first molding the housing 100 and then separately installing the power pin 200 and the signal pin 300, this can be manufactured efficiently.

[0049] It should be added that the signal contact component 3 and the power contact component 2 shown in the figure are both straight structures. Fig.11 For example, the lines connecting the power welding end 22, the power plug-in end 21 and the center of the power contact component 2 are parallel (180°), however, in other embodiments, according to actual installation conditions, the power welding end 22 and the power plug-in end 21 can also be configured as a bent structure with a set angle.

[0050] The specific embodiment of the adapter in the present invention: The embodiment of the adapter is the PCB end socket recorded in the embodiment of the above-mentioned combined socket, which will not be described in detail here.

[0051] Specific embodiments of the connector assembly in the present invention: The connector assembly includes a device-end socket and the adapter in the above-mentioned adapter embodiment. The device-end socket can be consistent with the prior art, that is, it includes a housing and a power pin and a signal pin arranged on the housing. It should be noted here that the length of the power pin and the signal pin of the device-end socket in this embodiment may not necessarily meet the requirement of passing through the through hole on the mounting plate directly. However, due to the existence of the adapter, for example Figure 4 In the case where it is difficult to connect to the PCB board normally, there is no need to extend the power pin and the signal pin, and the adapter can be used to achieve normal connection between the device end socket and the PCB board. Compared with the solution of extending the power pin and the signal pin, this solution is actually more convenient.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
