Description

Technical Field

[0001] The utility model relates to the field of socket structures, and particularly to a sunken connector socket. Background Art

[0002] A printed circuit board (PCB) is an important part of electronic products and is known as the "mother of electronic products". It is widely used in fields such as consumer electronics, automobiles, and communication equipment. PCB boards are divided into single-sided boards, double-sided boards, and multi-layer boards. Among them, single-sided boards have the most price advantages and are favored by the market. Therefore, price competition is more intense, and the requirements for the production process of manufacturers and the improvement of efficiency are becoming increasingly important.

[0003] Most existing lamp boards use single-sided boards. For example, in the field of security monitoring cameras, it is relatively common to use plug-in type for single-sided socket chip mounting in the industry. There are mainly two existing assembly methods:

[0004] The first is manual operation. As Figure 1 shown, the pins A3 of the connector socket A1 connected to the lamp board are respectively inserted into the corresponding pin holes A2 of the lamp board. During the assembly process, only manual plug-in operation can be performed, and automated chip mounting cannot be carried out. The production efficiency is low, and the processing cost is high.

[0005] The second is to attach the front of the connecting socket to the surface of the PCB. On the one hand, it is necessary to ensure the alignment of the PCB board and the connector socket, otherwise the subsequent welding quality will be affected. On the other hand, it is necessary to arrange the solder pads on the front of the PCB board and attach the entire socket to the front, which occupies a large space on the PCB board. Content of the Utility Model

[0006] To solve the problem of low production efficiency in the existing technology, the utility model provides a sunken connector socket.

[0007] The sunken connector socket of the utility model includes a PCB board and a connector socket assembly connected to the PCB board. The PCB board is provided with positioning holes, and solder pads are arranged around the positioning holes. The connector socket assembly includes a socket body and a plurality of connector pins connected to the socket body. The socket body can be inserted into the positioning holes, and the connector pins overlap around the positioning holes and are welded to the solder pads.

[0008] Further, the solder pads are arranged on the front of the PCB board, and the socket body extends out of the positioning holes and is arranged on the back of the PCB board.

[0009] Further, the insertion direction of the socket body is perpendicular or parallel to the PCB board.

[0010] Further, the pads are distributed on both sides of the positioning holes. The connector pins include a connection end connected to the socket body and a bent portion welded to the pads. The bent portions of different connector pins uniformly extend towards the pads on both sides of the positioning holes.

[0011] Further, the number of the pads is not less than the number of the connector pins.

[0012] Further, the positioning holes are adapted to the outer shape of the socket body.

[0013] Further, a limiting portion is provided on the socket body, and the socket body is stably arranged in the positioning holes through the limiting portion.

[0014] Further, the limiting portion is a buckle provided on the socket body. The buckle is clamped with the back surface of the PCB board away from the pads, and the socket body is fixed on the PCB board through the connector pins and the buckle.

[0015] Further, the limiting portion is an anti-slip block or an anti-slip ring provided on the connector socket assembly. The anti-slip block and the anti-slip ring are in interference fit with the side wall of the positioning holes for limiting.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model has a stable assembly, a reliable welding with the PCB board, and can be used for automated production.

[0017] The present utility model can adsorb the connector socket assembly through a suction nozzle and sink it into the positioning holes, realizing automatic alignment of the connector pins and the pads, thereby achieving automatic front-side surface mounting assembly, greatly improving the production efficiency; by sinking the connector socket body into the PCB board, it can not only effectively reduce the assembly space, but also limit the connector socket assembly, improving the stability of the product.

The terms "first", "second", etc. in the description and claims of the present utility model or the above drawings are used to distinguish different objects and are not used to describe a specific order.

[0023] When referring to "embodiment" in the present utility model, it means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears at various positions in the description and does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present utility model can be combined with other embodiments.

[0024] In order to enable those skilled in the technical field to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings.

[0025] As Figure 1 and Figure 2 shown, the sunken connector socket of the present utility model includes a PCB board 1 and a connector socket assembly 2 connected to the PCB board 1. A positioning hole 101 is provided on the PCB board 1, and a plurality of pads 102 are provided around the positioning hole 101. The connector socket assembly 2 includes a socket body 201 and a plurality of connector pins 202 connected to the socket body 201, and the socket body 201 can be inserted into the positioning hole 101.

[0026] In this example, the pads 102 are provided on the front side of the PCB board 1. When the socket body 201 is inserted into the positioning hole 101 through the front side of the PCB board 1 and extends out from the back side of the PCB board 1, the connector pins 202 overlap around the positioning hole 101 and are welded to the pads 102 one by one.

[0027] In this example, the insertion direction of the socket body 201 can be set parallel to the PCB board 1 as in the prior art, or perpendicular to the PCB board.

[0028] The PCB board 1 in this example is a lamp board. The connector pin 202 of this example is tightly inserted into the connector small hole of the socket body 201, and then tightly assembled into the connector socket assembly 2 through a jig. The mounter adsorbs the connector socket assembly 2 through a nozzle and steadily places it into the positioning hole 101 of the PCB board 1, and is installed on the front side of the PCB board 1 in a sunken manner, and the connection between the two is welded by printing solder paste, realizing the automatic assembly of the connector socket in this example.

[0029] The utility model can adsorb the connector socket assembly through a nozzle and sink it into the positioning hole 101, realizing the automatic alignment of the connector pin 202 and the pad 102, thereby realizing the automatic surface mounting assembly on the front side, greatly improving the production efficiency; by sinking the connector socket body into the PCB board 1, it can not only effectively reduce the assembly space, but also limit the connector socket assembly, improving the stability of the product.

[0030] In this example, a special design nozzle with a double-material and enlarged-diameter soft rubber head can be adopted to ensure that the seat can be adsorbed without dropping parts and shaking, thereby further improving the stability and assembly efficiency of the assembly.

[0031] As Figure 1 shown, as an embodiment of the utility model, there are 5 pads 102 in this example, the pads 102 are distributed on both sides of the positioning hole 101, and the connector pins 202 are also 5, including a connection end connected to the socket body 201 and a bending part welded to the pad. The bending part is perpendicular to the connection part and is arranged parallel to the PCB board 1. The bending parts of the 5 connector pins 202 extend uniformly towards the pads on both sides of the positioning hole and are arranged in one-to-one correspondence with the 5 pads 102.

[0032] The connector pins 202 are arranged in an opposite direction, realizing the expansion of the pad 102 area without changing the frequency pin pitch, so that the welding is more firm.

[0033] The positioning hole 101 in this example is adapted to the outer shape of the socket body 201. When the socket body 201 is inserted into the positioning hole 101, the assembly position can be defined by the positioning hole 101. The insertion direction of the socket body 201 in this example is perpendicular to the PCB board 1.

[0034] As Figure 2 shown, as another embodiment of the utility model, on the premise of not changing the structure of the PCB board 1 in the first embodiment, the compatibility of the 3PIN connector socket assembly 2 is realized. There are 3 connector pins 202 in the connector socket assembly 2 of this example, which are welded on the corresponding pads 102. In addition, a limiting part 203 is provided on the socket body 102 in this example, and the socket body 201 is stably arranged in the positioning hole through the limiting part 203.

[0035] In this example, the limiting part 203 is a rubber block or a flexible silica gel block. The socket body 102 is in interference fit with the side wall of the positioning hole 101 through the limiting parts 203 on both sides of the socket body 102, so as to realize the auxiliary fixed connection between the connector socket assembly 2 and the PCB board 1. In addition to setting the silica gel block in this example, an anti-slip ring can also be arranged along the periphery of the socket body 201, which can also achieve the auxiliary fixing effect.

[0036] As the third embodiment of the present invention, on the basis of the above embodiment, the silica gel block can be replaced by a buckle. The buckle is clamped with the back surface of the PCB board 1 away from the pad 102, and the socket body 201 is fixed on the PCB board through the connector pin 202 and the buckle.

[0037] The connector pins 202 in this example are not limited to being arranged in one direction, and can also be arranged in three directions or four directions. The shape of the positioning hole 101 is not limited to a square, and can also be a circle, an ellipse, etc.

[0038] The present invention can also be applied to sockets of other specifications, such as 4PIN. The pads in this example can also be set to other numbers according to actual situations, such as more than 5, so as to be compatible with the welding of sockets of more specifications.

[0039] Compared with the prior art, the present invention is assembled stably, welded firmly to the PCB board, and can be used for automated production. It not only improves the assembly efficiency, but also reduces the space occupied by the PCB board, thus effectively reducing the processing cost.

[0040] The above specific implementation manners are the preferred implementation manners of the present invention, and do not limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation manner. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
