Abstract

The utility model discloses an improved MICRO (Microcomputer) USB connector, which comprises an upper iron shell, a lower iron shell, a back rubber core, a terminal, a clamping hook, a front rubber core and a front shell. The back rubber core and the clamping hook are fixed on the front rubber core; the upper iron shell and the lower iron shell are covered at the outer end of the shell; the front shell is mutually matched with the lower iron shell through a positioning device; the positioning device is tinned after the front shell and the lower iron shell are assembled so as to firmly connect, thus, even if the front shell and the lower iron shell sway, the conductivity can be guaranteed, so that the product quality is guaranteed. In addition, the front end of the terminal is formed with a contact part with the adoption of a bending way, while the back end is connected with the back rubber core into a whole by with the using of an injection molding way, and the connection of the terminal and the back rubber core is firm, thereby the thickness of the product can be greatly reduced, and the high frequency performance is also very good.

Description

A kind of modified model MICRO USB connector

Technical field:

The utility model relates to technical field of electric connectors, especially relates to a kind of USB connector.

Background technology:

USB (Universal Serial Bus, i.e. serial data bus) connector is a kind of common connector, and is of many uses.There is weak point in a kind of MICRO USB3.0 connector commonly used at present on structural design, non-conductive because of waving easily between its fore shell and the following iron-clad when welding, influences product quality; In addition, its terminal front end adopts cutting way to form contact site, and the rear end then directly is plugged in the glue in-core, cause product thickness bigger, and high frequency performance is not good enough.

The utility model content:

The purpose of the utility model is to provide the weak point that exists to prior art and a kind of modified model MICRO USB connector is provided, when it can prevent the welding of MICRO USB connector because of waving nonconducting phenomenon between fore shell and the following iron-clad; In addition, it also has the characteristics that thickness is little, high frequency is prone to pass through.

For realizing above-mentioned purpose; The modified model MICRO USB connector of the utility model includes upper iron shell, following iron-clad, back glue core, terminal, grab, preceding glue core and fore shell; Wherein, On the glue core, upper iron shell was coated on the fore shell outer end with following iron-clad, cooperatively interacts through positioner between described fore shell and the following iron-clad before back glue core and grab were fixed on.

Preferred as technique scheme, described positioner is made up of with the location hole that is opened in down on the iron-clad the salient point that takes shape on the fore shell, and salient point and location hole cooperatively interact.

Preferred as technique scheme, described terminal front end bending forms contact site, and the terminal rear end is injection molded into one with back glue core.

Preferred as technique scheme, described terminal is two groups.

The beneficial effect of the utility model is: owing to cooperatively interact through positioner between fore shell and the following iron-clad, even fore shell occurs waving also with following iron-clad and can guarantee conductivity during the welding of MICRO USB connector, thus the assurance product quality.In addition, because the terminal front end adopts wrap direction to form contact site, the rear end then adopts the injection moulding mode to be connected as a single entity with back glue core, and terminal is very firm with being connected of back glue core, not only can reduce thickness of product greatly, and high frequency performance is also very good.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the decomposition texture sketch map of the utility model;

Fig. 2 is the local enlarged diagram at B place among Fig. 1.

Embodiment:

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection range of the utility model.

See illustrated in figures 1 and 2: the modified model MICRO USB connector of the utility model (MICRO USB3.0 connector) includes upper iron shell 10, down iron-clad 20, back glue core 30, two groups of terminals 40, grab 50, preceding glue core 60 and fore shells 70; Wherein, On the glue core 60, upper iron shell 10 was coated on fore shell 70 outer ends with following iron-clad 20 before back glue core 30 was fixed on grab 50; Have positioner between fore shell 70 and the following iron-clad 20, positioner is made up of with the location hole 21 that is opened in down on the iron-clad 20 salient point 71 that takes shape on the fore shell 70, and salient point 71 cooperatively interacts with location hole 21.Two groups of terminal 40 front ends at first adopt wrap direction to form contact site 41, afterwards, adopt the injection moulding mode to be connected as a single entity in two groups of terminal 40 rear ends and back glue core 30.
