Description

USB connector

Technical Field

The utility model relates to a connector technical field especially relates to a USB connector.

Background

In the interconnection of electronic circuits, a USB connector is an indispensable device in a circuit interconnection system, and the plug stability of the USB connector is critical.

In the prior art, there are also some designs that increase the USB and connect the steadiness, through set up the material of frictional property in interface department, increase frictional force and prevent not hard up of interface, such design, though can also prevent not hard up, nevertheless multiple grafting can make the wearing and tearing of plug part, influences normal use.

In view of the above technical problems, there is a need to provide a new USB connector to better solve the problem of the stability of the plug.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a USB connector, its simple structure, reasonable in design connects firmly.

The utility model adopts the technical proposal that:

a USB connector comprises a terminal assembly, a shell and a plastic connecting piece, wherein the plastic connecting piece is arranged in the shell and provided with a PIN slot for inserting the terminal assembly, the terminal assembly can be inserted into the PIN slot, and a spring plate and a lug are arranged on one side of the shell.

The further improvement to the technical scheme is that the shell is provided with a butterfly buckle and a buckling column which are matched with each other and are away from one side provided with the elastic sheet and the convex block.

The further improvement of the technical scheme is that the shell is also provided with a limiting block and a hasp component.

The technical proposal is further improved in that the plastic connecting piece is also provided with a positioning foot.

In a further improvement of the above technical solution, one end of the terminal assembly is provided with a blade structure, the other end of the terminal assembly is provided with a planar structure, one side of the terminal assembly provided with the planar structure can be inserted into the PIN slot, and an insertion position is limited by the end of the terminal assembly provided with the blade structure.

In a further improvement of the above technical solution, the terminal assemblies include 5 SMT terminals, and the lengths of the 5 SMT terminals are set to be the same.

The utility model has the advantages as follows:

the utility model discloses a terminal subassembly and casing still include the plastic connecting piece, the plastic connecting piece install in the casing, the plastic connecting piece is equipped with the PIN groove that is used for grafting terminal subassembly, the terminal subassembly can insert the PIN groove, casing one side is equipped with shell fragment and lug, its simple structure, and reasonable in design through setting up shell fragment and lug at the casing, will the utility model discloses when the female seat of cooperation uses, coincide more with female seat to guarantee not hard up about public mother when inserting, it is good to connect the steadiness.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1-4, the USB connector described in this embodiment, including terminal assembly 1 and casing 2, still include plastic connector 3, plastic connector 3 install in casing 2, plastic connector 3 is equipped with PIN groove 31 that is used for grafting terminal assembly 1, terminal assembly 1 can insert PIN groove 31, casing 2 one side is equipped with shell fragment 21 and lug 22, this embodiment simple structure, reasonable in design, through set up shell fragment 21 and lug 22 at casing 2, will the utility model discloses when the female seat of cooperation was used, it is more identical with the female seat to guarantee not hard up from top to bottom when public mother was to inserting, it is good to connect the steadiness.

In some embodiments, casing 2 deviates from the one side that is equipped with shell fragment 21 and lug 22, is equipped with assorted butterfly buckle 23 and lock post 24, and this embodiment is through such setting, and butterfly buckle 23 cooperates lock post 24, is convenient for the utility model discloses fixed glue behind the machine-shaping comes off when avoiding casing 2 to peg graft with the box, prevents simultaneously that plastic connecting piece 3 from shifting, thereby further ensures the utility model discloses a connect the steadiness.

In other specific embodiments, the housing 2 is further provided with a limiting block 25 and a buckle assembly 26, and the limiting block 25 and the buckle assembly 26 are arranged in this embodiment, when the plastic connector 3 is installed in the housing 2, the limiting block 25 limits the position of the plastic connector 3, and the plastic connector is buckled by the buckle assembly 26, so that the stable connection between the plastic connector 3 and the housing 2 is ensured.

In some specific examples, plastic connecting piece 3 still is equipped with location foot 32, and this embodiment is through setting up location foot 32, the utility model discloses when cooperating the PCB to use, can laminate with PCB board face, in order to guarantee the utility model discloses balance when adorning the PCB board prevents the slope.

In some embodiments, one end of the terminal assembly 1 is configured as a blade structure, the other end of the terminal assembly 1 is configured as a planar structure, one side of the terminal assembly 1 configured as a planar structure can be inserted into the PIN slot 31, and the insertion position is limited by the end of the terminal assembly 1 configured as a blade structure, in this embodiment, when the terminal assembly 1 is inserted into the PIN slot 31, the terminal assembly 1 and the plastic connector are in interference fit, the terminal assembly 1 does not exit from the PIN slot 31, and the connection is stable.
