Description

A welded fixed structure

technical field

The utility model relates to wire welding in the electronic field, in particular to a welding fixing structure.

Background technique

At present, the functions of high-frequency transmission cables are becoming more and more integrated, and the capacity of signal transmission is increasing. New multi-channel technology is used for multi-pair transmission. The design of the new TYPE C connector is flat and thin, changing the working mode of the traditional connector and adopting a new detection mode. When the board is welded, the traditional manual welding method is no longer applicable, and there are disadvantages of low welding efficiency and poor welding quality.

Therefore, the welding process of PCB circuit boards and wires has become a manufacturing bottleneck, which is inconvenient for manufacturing personnel and prone to quality abnormalities.

Utility model content

In order to overcome the above disadvantages, the utility model provides a welding and fixing structure, which can pre-arrange the wires, and at the same time position and connect the wires and PCB boards to facilitate machine welding, improve product quality, reduce the unqualified rate, and save manpower and materials. .

In order to achieve the above purpose, the technical solution adopted by the utility model is: a welding and fixing structure, including a body, the body is a bar-shaped structure, the upper row and the lower row are equipped with a plurality of spacer teeth, and the adjacent spacer teeth A wire groove is formed between them, and the size of the wire groove is different. A fixed end is reserved between the upper and lower limit teeth, and the fixed end is provided with a fixed groove at both ends of one side;

Further, the upper end of the limit tooth is a circular arc convex end, and the lower end is a circular arc concave end, and the upper row of limit teeth and the lower row of limit teeth are center-symmetrical in arrangement spacing;

Further, the fixing grooves at both ends are strip-shaped embedded structures with different sizes.

The working principle of this structure is as follows:

Discharge the wire into the wire groove in a designed way. Specifically, the wire first squeezes through the arc protruding end of the upper end of the limit tooth, and enters the inner concave end of the lower end of the arc. At this time, the protruding structure of the upper end can play a role. The role of wire fixing.

Then the fixed feet on the PCB board are embedded in the fixed grooves, because the fixed feet have different sizes, and their sizes correspond to the fixed grooves on the fixed end, so the positive and negative directions of the PCB board can be determined, and it can be precisely fixed and matched with the welding fixing structure. The fixing of the wire rod by the wire rod groove can realize the precise positioning of the wire rod and the PCB board.

To sum up, the utility model can pre-arrange the wires, and at the same time position and connect the wires and the PCB board, which facilitates machine welding, improves product quality, reduces unqualified rate, and saves manpower and materials.

Among them: 1. Body; 11. Limiting tooth; 12. Fixed end; 13. Wire groove; 111. Protruding end of circular arc; 112. Concave end of circular arc; 121. Fixed groove; 100. Cable; 200. PCB board; 300, fixed feet.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Example 1:

Referring to Fig. 1 and Fig. 3, a welding fixing structure includes a body 1, the body 1 is a bar-shaped structure, the upper row and the lower row are provided with a plurality of stop teeth 11, and the adjacent stop teeth 11 A wire groove 13 is formed between them, and the size of the wire groove 13 is different. A fixed end 12 is reserved between the upper and lower limit teeth 11, and the fixed end 12 is provided with a fixed groove 121 at its two ends.

In the above, the upper end of the limiting teeth 11 is a circular arc convex end 111, and the lower end is a circular arc concave end 112, and the spacing between the upper row of limiting teeth 11 and the lower row of limiting teeth 11 is center-symmetrical.

Specifically, as shown in Figure 2, the cable 100 interacts with the fixed structure. Specifically, the wire is discharged into the wire groove 13 in a designed manner. Specifically, the wire first squeezes through the circle at the upper end of the limit tooth 11. The arc protruding end 111 enters the arc concave end 112 at the lower end, and at this time, the protruding structure at the upper end can play a role in fixing the wire.

Preferably, the fixing grooves 121 at both ends are strip-shaped embedded structures, and their sizes are different, which have the function of fool-proofing and fixing. Specifically, the size is consistent with the size of the fixing feet 300 on the PCB board 200. Continue to refer to the attached Fig. 2, the fixed pin 300 on the PCB board 200 is embedded in the fixed slot 121, because the fixed pin 300 has a size difference, and its size corresponds to the fixed slot 121 on the fixed end 12, so the positive and negative directions of the PCB board 200 can be determined, and It can be precisely fixed with the welding fixing structure, and cooperate with the fixing of the wire rod by the wire rod groove 13 to realize precise positioning of the wire rod and the PCB board 200 .

After the soft wire is perfectly and accurately positioned on the structure and the PCB board 200, machine welding can be conveniently carried out, the welding efficiency of the product can be improved, and the product quality can be improved at the same time, thereby reducing the failure rate, and the machine welding can also Save manpower and materials, reduce production costs.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly, and not to limit the protection scope of the utility model. All equivalent transformations or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
