Detailed Description

In order to facilitate the normal connection between the equipment end socket and the PCB board, the basic technical idea of the present utility model is to provide a combined socket formed by combining two independent parts, wherein one part is used for connecting equipment, i.e. the equipment end socket, and the other part is used for connecting the equipment end socket and the PCB board, i.e. the PCB end socket, which is also equivalent to an adapter, and the PCB end socket comprises a signal contact part and a power contact part, and can be connected with the PCB board first during assembly. The normal connection of the equipment end socket and the PCB can be realized without setting the power pin and the signal pin of the equipment end socket longer, so that the equipment end socket can directly penetrate through the through hole of the mounting plate, and the risk of damage caused by the collision of the power pin and the signal pin with the mounting plate is greatly reduced. The present utility model is described in further detail below with reference to examples.

The utility model provides a specific embodiment of a combined socket, which comprises the following steps:

as a most basic embodiment, the connector assembly provided in this embodiment is generally shown in fig. 6, and includes a device-side socket and a PCB-side socket (corresponding to an adapter). The device-side receptacle includes a housing 100, and power pins 200 and signal pins 300 mounted on the housing 100. In use, as shown in fig. 15-18, the housing 100 may be secured to a mounting plate 500, and the power pins 200 and signal pins 300 may pass through holes in the mounting plate 500. The basic structure of the PCB end socket is shown in fig. 7, and includes an insulator 1, on which a signal contact part 3 and a power contact part 2 are mounted on the insulator 1. The insulator 1 mainly serves as a basis for mounting the signal contact member 3 and the power contact member 2, and insulation is a basic requirement thereof. The signal contact part 3 and the power contact part 2 are each provided with a PCB connection terminal for electrically conductive connection with the PCB board 400 and an equipment socket connection terminal for electrically conductive connection with the equipment socket. As shown in fig. 17, when the parts are assembled so that the device-side socket and the PCB 400 are connected, the PCB-side socket may be connected with the PCB through the PCB connection end, the power pins 200 and the signal pins 300 in the device-side socket may pass through the through holes of the mounting board 500, and the device-side socket connection end of the PCB-side socket is connected with the device-side socket, thereby achieving normal connection of the device-side socket and the PCB.

As can be seen from analyzing the above structure, unlike the prior art (fig. 1), the lengths of the power pin 200 and the signal pin 300 of the device-side socket in the present embodiment are not required to be too long, and when the device-side socket is installed, the device-side socket has a straight-through portion, that is, the portion corresponding to the right side of the mounting board 500 in fig. 17 and 18, and the straight-through portion can directly penetrate through the through hole of the mounting board 500 in the posture that the housing 100 shown in fig. 17 and 18 is perpendicular to the mounting board 500, so that the operation is convenient, and meanwhile, the risk that the power pin 200 and the signal pin 300 touch the mounting board 500 can be greatly reduced, so as to solve the problem of pin damage. For the case that the PCB board is far from the through hole on the mounting board as shown in fig. 4, the existence of the PCB end socket also makes the device end socket be normally connected with the PCB board, which is convenient for use.

As a preferred embodiment for facilitating connection of the device-side socket and the PCB-side socket, in this embodiment, the device-socket connection terminals of the signal contact part 3 and the power contact part 2 are configured to be provided with opposite-plug terminals of an opposite-plug structure, that is, the signal contact part 3 and the power contact part 2 are both parts including a jack structure. As shown in fig. 11 to 13, the signal contact part 3 and the power contact part 2 may each be of a tuning fork type as shown in the drawings, i.e., a structure including elastic arms on both sides to clamp the corresponding pins, and accordingly, the opposite terminals are a signal opposite terminal 34 and a power opposite terminal 21 as shown in the drawings, respectively. Of course, the opposite-inserting structure may be a cylindrical and spring claw type inserting hole structure.

When the device-side socket and the PCB-side socket are connected, as shown in fig. 17, after the device-side socket is mounted in place, the whole body formed by the PCB 400 and the PCB-side socket is moved to the PCB-side socket and the device-side socket in the direction indicated by the arrow in the figure. Compared with other connecting modes (such as welding, crimping and bolting) adopted in other embodiments, the preferred embodiment is obviously more convenient, facilitates automatic assembly, improves efficiency and reduces manual labor intensity.

On the basis of the above preferred embodiment, in order to facilitate accurate plugging of the equipment-side socket and the PCB-side socket, as a preferred embodiment, the insulator 1 is provided with a guide structure for guiding and cooperating with the equipment-side socket, and the guide structure extends in a direction in which the opposite plug-in terminal and the equipment-side socket are opposite. Thus, the plugging can be completed under the condition that the centering of the equipment end socket and the PCB end socket is ensured.

Specifically, as an embodiment with better guiding and limiting effects, as shown in fig. 10, the guiding structure on the insulator 1 includes a guiding groove 4, and correspondingly, as shown in fig. 15 and 17, a guiding protrusion 600 is provided on the device-end socket, and the guiding groove 4 is provided for the guiding protrusion 600 to enter and move relative to the guiding protrusion 600 during the insertion process. It will be appreciated that in other embodiments the positions of the guide slot 4 and the guide projection 600 may be interchanged, i.e. the guide structure on the insulator 1 comprises a guide projection, and correspondingly, in this case a recess (corresponding to the guide slot) is provided in the equipment end socket, the guide projection being intended to enter the mating recess and to move relative to the recess during the mating process.

It should be noted here that the guide structure is not limited to the above-described projection or groove structure. For example, in other embodiments, the side wall of the insulator 1 on the side facing the opening of the equipment-side socket may be regarded as a guide structure, and the equipment-side socket may slide along the inner wall surface of the side wall when the equipment-side socket is plugged, and may also serve to guide the plugging.

To facilitate the manufacturing and assembly of the PCB end socket, in some preferred embodiments the power contact member 2 is configured as a unitary structure and is forcibly secured to the insulator 1. Specifically, as shown in fig. 11, the power contact part 2 includes a strong-fitting portion 23, the PCB connection end, and the device socket connection end are integrally structured, and as shown in fig. 8 to 10, a strong-fitting slot 5 is provided on the insulator 1, and the strong-fitting portion 23 is inserted into the slot so that the power contact part 2 is fixed with respect to the insulator 1. The groove depth direction of the strong-fitting groove 5 is along the direction vertical to the paper surface in fig. 8, and the groove cavity below the strong-fitting groove 5 in fig. 8 is used for installing and accommodating the power contact component. The strong fitting is understood here to mean a tighter tight fit between the insulator 1 and the strong fitting 23, with a greater friction between the two such that the insulator 1 and the power contact part 2 remain relatively fixed. The integrated direct strong-fitting power contact component 2 is simpler in structure, simple in installation process and more convenient to assemble and produce.

Preferably, in order to enable a larger holding force between the power contact part 2 and the insulator 1, as shown in fig. 11, the strong fitting portion 23 is further provided with a barb structure 231, and the strong fitting portion 23 is interference fit with the strong fitting slot 5 through the barb structure 231, and the barb structure 231 is configured to enable a larger holding force between the power contact part 2 and the insulator 1, thereby improving stability.

Likewise, to facilitate assembly and manufacture of the PCB end socket, in some preferred embodiments, the signal contact member 3 is configured as a composite structure comprising a sheath 31 and contact conductors, which are secured to the insulator 1 by the sheath 31. Specifically, as shown in fig. 12 and 13, for such a case that it is insertable with respect to the signal pin 300, the contact conductive member inside the sheath 31 is the signal contact member 32. The sheath 31 can be connected without the need for additional adapters. Of course, in the case where the signal pin 300 is not connected by such a butt-insertion method, the contact conductive member inside the sheath 31 is a signal contact terminal.

Specifically, the elastic sheet 33 (elastic fin) may be disposed on the sheath 31, and accordingly, a stepped hole is formed in the insulator 1, and in the state shown in fig. 13, the sheath 31 moves upward, and the elastic sheet 33 may be released after entering the part with a larger caliber from the smaller caliber end of the stepped hole, so that the function of fixing the signal contact member 3 may be achieved, and the operation is convenient. However, in other embodiments, the case of strongly fixing the sheath 31 and the insulator 1 is not excluded.

In order to facilitate connection between the PCB 400 and the PCB terminal socket, as a preferred embodiment, as shown in fig. 11-14, the PCB connection terminals of the signal contact part 3 and the power contact part 2 are welding terminals for welding with the PCB 400, that is, the power welding section and the signal welding terminal 35 in the corresponding drawings respectively, and the power welding terminal 22 and the signal welding terminal 35 are sheet structures that can be inserted into the PCB 400, and when connected, the power welding terminal 22 and the signal welding terminal 35 can be conveniently and automatically welded with high efficiency after being inserted into the PCB 400. In other embodiments, if the signal contact member 3 and the power contact member 2 are both circular, the power soldering terminal 22 and the signal soldering terminal 35 are both columnar structures that can be inserted into the PCB 400.

To facilitate manufacturing of the device-end receptacle, as shown in fig. 16, the power pin 200 and the signal pin 300 may be integrally inserted into the housing 100 using an insert injection process (prior art). This allows for efficient manufacturing as compared to a solution where the housing 100 is molded first and then the power pin 200 and the signal pin 300 are mounted separately.

It should be noted that, in the drawings, the signal contact part 3 and the power contact part 2 are both in a straight structure, and as an example in fig. 11, the connecting lines of the centers of the power welding end 22, the power opposite plug end 21 and the power contact part 2 are parallel (180 °), but in other embodiments, the power welding end 22 and the power opposite plug end 21 may be configured to have a bent structure with a set angle according to actual installation conditions.

Specific embodiments of the adapter of the present utility model:

the PCB-end socket described in the above-described embodiment of the combination socket is not described in detail here.

Specific embodiments of the connector assembly of the present utility model:

The connector assembly includes the device-side socket and the adaptor in the above-mentioned adaptor embodiment, the device-side socket may be consistent with the prior art, that is, includes the housing and the power pins and the signal pins disposed on the housing, and it should be noted here that the lengths of the power pins and the signal pins of the device-side socket in this embodiment do not necessarily meet the requirement of directly penetrating the through holes on the mounting board, but due to the adaptor, for the case that it is difficult to connect with the PCB board normally as shown in fig. 4, it is unnecessary to lengthen the power pins and the signal pins any more, and the normal connection between the device-side socket and the PCB board can be achieved through the adaptor. This solution is also in fact more convenient than the one in which the power pins and signal pins are extended.

It should be noted that the above-mentioned embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited to the above-mentioned embodiments, but may be modified without inventive effort or equivalent substitution of some of the technical features thereof by those skilled in the art.
