Abstract

The utility model discloses a USB connector. The USB connector is characterized in that: the connector comprises a metal housing, a plastic body and two groups of terminals, wherein the terminals are arranged in the plastic body. The number of terminals in one group is four and the number of terminals in the other group is five. Tin soldering points of the two groups of terminals are distributed on the same plane. The plastic body is arranged in the metal housing, and the front end of the plastic body is provided with two protruding plastic columns. The tin-soldering points of the terminals are semicircle solder cups. A connector wire clamp is provided with grooves corresponding to the plastic columns. The USB connector has the advantages of improving production efficiency, reducing production cost, optimizing production processes, and improving product quality.

Description

A kind of USB connector

Technical field

The utility model relates to a kind of USB connector, and specifically a kind of enhancing productivity, reduce production costs, optimized production process, the USB connector of improving the quality of products.

Background technology

USB3.0A type male seat and female seat wire welding type interface are all the project organizations that adopt the 9Pin terminal, the current current production technology that appears on the market generally has two kinds: one is two groups respectively has a strip to be connected, adopt the technology of punching press respectively or injection moulding, 4 butt of compatible 2.0 are one group of punching press and injection moulding, be that 3.0 other 5 butt of preparing are divided into one group of punching press and injection moulding, then pass through the design of plastic cement structure, two different parts are snapped together, this operation is more, and is very uneconomical.Another kind is that two groups of terminals are at a strip, by bending, make 4PIN and 5PIN not on same plane, then fall strip with folding after the MOLDING injection mo(u)lding, refilling shell. the shortcoming of the first is that the cost waste is large, operation is many, uneconomical. the shortcoming of the second way is the complex structure of terminal, and cost of stamping is high, the mold repair expense is high, and fraction defective is high. and the solder joint of this type of design is not all same plane, has greatly increased the cost of welding, the solder joint on plane is not easy to scolding tin, and can not realize disposable automatic welding.

Summary of the invention

The purpose of this utility model is to provide a kind of enhancing productivity, reduces production costs, and optimized production process, the USB connector of improving the quality of products.

The purpose of this utility model is achieved in that

A kind of USB connector, it is characterized in that: described connector comprises a metal shell, a plastic body and two groups of terminals, terminal is arranged in plastic body, one group of terminal in terminal is four, another group terminal is five, two groups of terminal bumps distribute at grade, and plastic body is arranged in metal shell, and the front end of plastic body is provided with two outstanding glue posts.

The bump of described terminal is semicircle weldering cup.

Described connector wire clamp is provided with the groove corresponding with the glue post.

The utility model compared with prior art has the following advantages:

The utlity model has and enhance productivity, reduce production costs, optimized production process, the advantage of improving the quality of products.

Embodiment

Below in conjunction with accompanying drawing, the utility model embodiment is elaborated.

as shown in Figures 1 to 12, USB connector described in the utility model comprises plastic body 1,

terminal

3, 4,

strip

2, 5, wire clamp 7, plastic body is positioned at metal-back 6, terminal is positioned at plastic body, terminal is that two groups of same planes distribute, one end and the strip 2 of two groups of terminals are connected as a single entity, one group of terminal 3 in terminal is five, another group terminal 4 is four, terminal is by distortion, make terminal 3 and terminal 4 be distributed in same strip, semicircular weldering cup 3.1 and 4.1 is designed in junction, two groups of terminals can generate an integral body by a punching press, the scolding tin pin plane of terminal just is positioned at the same plane on termination contact plane or opposite one side, other end ledge in terminal 3 or terminal 4, design strip 5, can well control its evenness, the two ends of two groups of terminals are all left and are prejudged design, can easier separate, after punching press is electroplated, first remove strip 5, pass through again single injection-molded, then remove strip 2, mix again shell, just can be very convenient and economical produce a USB3.0 connector.

USB connector terminal 3 described in the utility model, 4 solder joint 3.1 and 4.1 are positioned at a row, terminal scolding tin pin plane just be positioned at the same plane on termination contact plane or opposite one side.Plastic body 1 is designed 2 outstanding glue posts 1.1, design corresponding groove 7.1 in wire clamp 7, wire rod 8 snaps in respectively in wire clamp 7 and carries out separated time, then will be placed on the line of wire clamp on USB connector, glue post 1.1 just and groove 7.1 combine closely, make two

plastic bodies

1 and 7 be buckled into an integral body, put it into again in automatic welding machine, semicircular weldering cup makes the machine automatic welding efficiently convenient, thereby is easy to just complete welding process, very convenient saving time.

Above a kind of USB3.0 connector that the utility model is implemented to provide is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in embodiment and range of application, in sum, this description should not be construed as restriction of the present utility model.
