The device adopts the technical scheme that a supply socket fixing device comprises a PCB and a supply socket, wherein the supply socket is installed on the PCB; pins of the supply socket are electrically connected with the PCB; fixing buckles are installed on the supply socket; the shape and the size of the fixing buckle are matched with the profile of the supply socket; and the fixing buckles are fixed on the PCB. The device greatly improves the stability and the reliability of the supply socket, the fixing buckles are simple to assemble and convenient to install, the production cost is low, and the device is very suitable for assembling the supply socket on the PCB.

Description

A kind of supply socket fixture

Technical field

The utility model relates to the supply socket mounting technology, and particularly supply socket is in printed circuit board (PCB) (Print Circuit Board, PCB) fixture on.

Background technology

The power supply of PCB need be connected with power-supply system or electrical network by supply socket, uses following scheme in the prior art usually:

Scheme 1: supply socket is fixed on the device housings, adopts the mode of cable fly line that the supply socket pin is connected on the PCB.The supply socket mounting means that this employing cable connects, the assembling more complicated, the production and assembly cost is than higher.

Scheme 2: supply socket directly is installed on the PCB, and its pin is welded direct to PCB and upward is connected with circuit.This supply socket mounting means, supply socket only relies on pin to fix, fixing insecure, in the plug process, become flexible easily, particularly AC Power supply socket, it has 3 connecting lines, plug need overcome bigger resistance, and socket pins is stressed bigger, causes pin scolding tin loose or dislocation easily, fault such as produce loose contact, open circuit reduces power supply reliability.

The utility model content

Technical problem to be solved in the utility model is exactly at prior art supply socket assembling is complicated, cost is high and the shortcoming of fixing insecure, pin scolding tin loose or dislocation, and a kind of device of reinforcing supply socket is provided.

The utility model solve the technical problem, the technical scheme that adopts is, a kind of supply socket fixture, comprise PCB and supply socket, described supply socket is installed on the described PCB, and described supply socket pin is electrically connected with PCB, it is characterized in that, in the described supply socket clip is installed, described clip shape and size and described supply socket profile phase coupling, described clip is fixed on the described PCB.

Described supply socket is an AC Power supply socket.

Described clip is made of the sheet metal bending.

Described clip two ends are processed with translot and vertical slot respectively.

Described translot height 〉=described PCB thickness.

The hole that described clip two ends are passed on the PCB is fixed on the described PCB.

Hole on the described PCB is a plated-through hole.

The beneficial effects of the utility model are improved the stability and the reliability of supply socket greatly, and the clip assembling to be simple, flexible for installation, production cost is low.

Embodiment

Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.

The utility model supply socket fixture comprises PCB, supply socket and clip.Supply socket is installed on the described PCB, and the supply socket pin is welded on PCB and is electrically connected.Clip is placed the corresponding fixed position of supply socket, and be fixed in PCB, thereby supply socket is anchored on the PCB.Clip shape and size requirements and supply socket profile phase coupling can make supply socket be securely fixed on the PCB more.

Embodiment 1

As shown in Figure 1, the supply socket fixture that this is routine comprises PCB11, supply socket 31 and clip 21.This routine supply socket 31 is an AC Power supply socket, and PCB is close in supply socket 31, and its pin 311 passes PCB11 and welds, and realizes being electrically connected with PCB, grid alternating current is introduced in the circuit unit of PCB11.These routine clip 21 structures are made of the sheet metal bending as shown in Figure 2, have the convenient characteristic of simple of making of drawing materials.Clip 21 two ends are processed with translot 211 and vertical slot 212 respectively, and the height of translot 211 equates that with PCB thickness clip 21 passes the hole 111 on the PCB11 when being convenient to assemble, and translot 211 is stuck on the PCB11, realize precision-fit, strengthen fixation.The effect of vertical slot 212 can make the two ends of clip 21 have certain elasticity, is convenient to assembling and fixing.The bending shape of clip 21 and supply socket 31 profile phases coupling are placed on supply socket 31 corresponding positions, and clip 21 are passed PCB weld fixing.The shape of this routine clip 21 and size all are complementary with supply socket 31, thereby supply socket 31 is anchored on the PCB, may cause supply socket 31 pins loosening when so just having prevented plug, improve the reliability that supply socket is installed.

Embodiment 2

As shown in Figure 3, when the thickness of PCB11 height less than the translot on the clip 21 211, and size exists than big-difference, when clip 21 can not be realized closely fixedly with PCB11, after supply socket 31 assembled with PCB11, again clip 21 is assembled to supply socket 31 corresponding positions, at this moment utilize the end distortion certain angle of instrument (as nipper pliers etc.) again with clip 21, realize closely cooperating of clip 21 and PCB11, supply socket 31 is fixing, and this mode can reach closely fixing effect equally.Other structures of this example are referring to the description of embodiment 1.

Embodiment 3

As shown in Figure 4, in order further to improve the reliability of supply socket assembling, the perforate on the PCB 11 111 can be carried out metalized, make it become plated-through hole (perisporium in hole 111 generates layer of metal film), can with clip 21 by being welded into integral body, add the fastness of strong weld.After supply socket 31 assembled with PCB 11, again clip 21 is installed to the relevant position of supply socket 31, at this moment utilizes scolding tin 41 that clip 21 is fixing with PCB 11 welding again, thus supply socket 31 is fixing.Other structures of this example are referring to the description of embodiment 1.
