In an embodiment, the PCB board 5 is provided with a positioning hole 8 matched with the positioning column 6.

In the embodiment, the bottom of the grounding plate 3 is provided with a grounding plate welding groove 35.

For the convenience of understanding the technical solution of the present invention, the following detailed description will be made of the technical solution of the present invention through a specific use mode.

When specifically using, according to an electric shock prevention socket, it comprises gluey core, terminal, grounding piece and high temperature adhesive tape, the terminal is the carrier of transmission power and signal, the product is installed PCB board back its and is always in charged state, for preventing that personnel are difficult for touching it, the terminal top surface is higher to gluing the planar relative position of core, even go the touching with minimum finger, the terminal top surface also can not touch with the finger, the terminal top surface still has certain safe distance to gluing the core plane to guarantee its good security. As shown in fig. 3, the process flow diagram is as follows: the method comprises the steps of inserting terminals → bending the terminals → installing ground pieces → pressing the ground pieces → pasting high-temperature adhesive paper → inspecting finished products.

As shown in fig. 3-5, after the terminal is inserted into the plastic, the terminal is bent, the bending surface is welded with the solder paste on the PCB, in order to ensure that the terminal has the problem of pine needle due to expansion and contraction caused by high temperature during welding, a clamping point is arranged on the terminal, the clamping point is in a barb shape, and after the clamping point is inserted into the plastic, the clamping point in the barb shape can clamp the plastic, thereby improving the holding force of the terminal. For further promoting the intensity behind the product welding PCB board, except that the terminal welding, it has the earthing lug still to design on gluey core both sides, possess the face of weld above the earthing lug, this face of weld also with the terminal weld the PCB board together on, for promoting the welding strength of earthing lug, open the centre of the face of weld of earthing lug has the welding groove, the welding groove is opened and is increased three face of weld, the face of weld is more, the tin cream will be more with the face of weld contact, this can directly promote its welding strength. For providing great fixed power after guaranteeing the face of weld and the plastic equipment, the design has two or above stuck point structures above the grounding lug, this stuck point is interference fit with gluing the core draw-in groove, pierce when the stuck point and glue behind the core draw-in groove, under interference fit's effect, the plastic above the gluey core can the flow phenomenon appear, because the interference interferes the peripheral plastic material of stuck point and can be extruded inside the grounding lug draw-in groove, it is more to extrude the plastic material of draw-in groove the inside, the grounding lug will be big more with the fixed power of gluing the core, the fixed power is big more, the installation strength of product will be better.

As shown in fig. 2, for further installation intensity and anti-swing performance of promotion product on the PCB, still design the reference column above the gluey core, this reference column passes the locating hole on the PCB, under the condition that sways appears in the product, this reference column also can bear external force impact and promote the impact strength of whole product with terminal and grounding lug together, this reference column is except bearing external force, still possess the location and prevent slow-witted function, after the product is installed the PCB, owing to there is the reference column, the relative welding position of terminal and grounding lug can not appear the condition of misplacing, can guarantee welded product position precision from this, in addition, if the product is inserted anti-reversely, the product just can't accurately insert on the PCB, thereby possess and prevent slow-witted function.

In order to improve the production efficiency of a client, high-temperature adhesive paper is designed on the product, after the product is assembled, the high-temperature adhesive paper is pasted on the top surface of the adhesive core, then the tape is packaged, the tape can be installed on a full-automatic chip mounter by the client, during production, a suction nozzle on the chip mounter directly sucks the high-temperature adhesive paper, and then the product is automatically placed in a welding position corresponding to a PCB, so that the aim of full-automatic production is fulfilled.

In order to further improve the connection strength between the socket and the plug, the socket is further provided with a clamping block, and under the condition of being connected with the plug, the clamping hook on the plug can clamp the clamping block, so that the separating force between the plug and the socket is greatly improved, the product can be prevented from easily falling off in the working process, and the connection reliability of the product is improved.

According to the different welding processes of the client, the scheme is provided with a wave soldering process besides the existing surface mounting process, namely, the pin tails of the terminals are straight pins, and then the pins penetrate into holes of a PCB (printed circuit board) to be soldered, wherein a schematic diagram is shown in FIG. 6.

In summary, with the above technical solution of the present invention, by setting the distance from the terminal top surface to the rubber core plane to be greater than the maximum distance that can be pressed by a finger, even if the smallest finger is used to touch the rubber core top surface, the terminal top surface will not touch the finger, thereby ensuring good safety; the rubber core is fixed with the PCB through the positioning column, so that the impact strength and the swing resistance of the product are improved; when the clamping block is connected with the plug, the clamping hook on the plug can clamp the clamping block, so that the separating force between the plug and the socket is greatly improved, the product can be ensured not to easily fall off in the working process, and the connection reliability of the product is ensured.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
