Along with the development of science and technology, electronic products are continuously developed, people are increasingly unable to leave electronic products in life, electronic products such as mobile phones and computers become necessities in life, and USB connectors are needed for data transmission and charging among electronic products, so that the USB connectors are simplified, the cost is reduced, and USB AM short connectors are present in the market at present.

At present, many USB AM short body connectors solve the problem of shielding through welding the ground wire at the back, however, the mode production process is comparatively troublesome, needs to consume a large amount of manpower, and in the production process, too big solder joint can cause forming in-process irregular, and the iron shell is crushed moreover, causes salt fog not up to standard, forms the defective products.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a USB AM short body structure, which can effectively solve the technical problem that the ground wire is welded on the back of the connector shell manually to solve the shielding problem.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a short body structure of USB AM, comprises casing, rubber core and terminal, the rubber core is pegged graft in the casing inside fixedly, the rubber core surface is equipped with at least three trench, the terminal has at least three and assembles respectively in different trench, casing one side is equipped with the extension piece of integral structure, extend to adjacent trench bottom and terminal contact after bending the extension piece.

Further, one end of the rubber core extends to the outer side of the shell.

Further, the slots are distributed in parallel and lead from the outside to the inside of the housing.

Further, a connecting portion contacting with the terminal insertion end is provided at the end of the housing away from the extension piece.

Further, the protrusions on two sides of the terminal are in a U-shaped structure.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the extending sheet with an integrated structure is added on the connector shell, and the extending sheet is bent and then extends into the groove for forming the negative end to automatically short-circuit, so that the ground wire does not need to be welded at the bottom during use, the production process is simplified, the production efficiency is improved, the defective rate is reduced, the surface damage of the shell is avoided, the whole structure is simple, the operation is convenient, and the practicability is strong.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-5, the utility model provides a USB AM short body structure, which consists of a shell 1, a rubber core 2 and a terminal 3, wherein the rubber core 2 is inserted and fixed in the shell 1, when the rubber core 2 is inserted and connected in the shell 1, the position of a bulge in the middle of the rubber core 2 is fixed with the shell 1, and one end of the rubber core protrudes out of the shell 1, so that the rubber core is convenient to weld and use.

The rubber core 2 is provided with at least three slots 4 on the surface, the terminals 3 are at least three and are respectively assembled in different slots 4, in the technical scheme, the number of the slots 4 is four, the terminals 3 are all used for welding and fixing the housed terminals 3, the terminals 3 form a structure with a U-shaped section, the wires are conveniently placed for welding, all the slots 4 are distributed in parallel, the terminals 3 are led to the inner side of the shell 1 from the outer side of the shell 1, the outer end of the terminals 3 is used for welding the wires, the four terminals 3 are respectively connected with wires of four colors of red, white, green and black, and the shell 1 is far away from the welding conductive end and is provided with a connecting part 6 which can be connected with all the terminals 3.

The extension piece 5 of an integral structure is arranged on one side of the shell 1, the extension piece 5 is bent and then extends to the bottom of the adjacent slot 4 to be in contact with the terminal 3, the extension piece 5 is clung to the bottom of one slot 4 in an extending mode, usually the slot of the fourth cathode, is in contact with the welded terminal 3 to form a ground wire, at the moment, the ground wire does not need to be welded again at the bottom of the shell 1, the manufacturing process is simplified, and the surface damage of the shell 1 is avoided.

Compared with the prior art, the technical scheme has the advantages that the extending piece of an integrated structure is added to the connector shell 1, the extending piece 5 is bent and then extends to the groove position 4 forming the negative end to automatically short-circuit, the ground wire does not need to be welded again at the bottom during use, the production process is simplified, the production efficiency is improved, the defective rate is reduced, the surface damage of the shell 1 is avoided, the integral structure is simple, the operation is convenient, and the practicability is strong.
