Abstract

The utility model discloses an improved MICRO USB (Universal Serial Bus) connector. The improved MICRO USB connector comprises an upper iron casing, a lower iron casing, a rear rubber core, terminals, a clamping hook and a front rubber core. The rear rubber core and the clamping hook are fixed on the front rubber core. The upper iron casing and the lower iron casing are wrapped on the outer ends of the front rubber core. The front end of each terminal is bent to form a contact portion, and the rear end of each terminal is injection-molded with the rear rubber core to be one body. The front end of each terminal is bent to form the contact portion, the rear end of each terminal is injection-molded with the rear rubber core to be one body, and the terminals are firmly connected with the rear rubber core, such that the connector of the utility model allows the thickness of a product to be substantially reduced and exhibits wonderful high frequency performance.

Description

A kind of MICRO USB connector of improvement

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 USB2.0 connector commonly used at present on structural design, 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 MICRO USB connector of improvement is provided, and it has the advantages that thickness is little, high frequency is prone to pass through.

For realizing above-mentioned purpose; The USB connector of the improvement of the utility model includes upper iron shell, following iron-clad, back glue core, terminal, grab and preceding glue core, wherein; Back glue core and grab are fixed on the preceding glue core; Glue core outer end before upper iron shell is coated on following iron-clad, described terminal front end bending forms contact site, and the terminal rear end is injection molded into one with back glue core.

Described terminal is one group.

The beneficial effect of the utility model is: 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; 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 A 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 MICRO USB connector of the improvement of the utility model (MICRO USB2.0 connector) includes upper iron shell 10, down iron-clad 20, back glue core 30, one group of terminal 40, grab 50 and preceding glue core 60; Wherein, On the glue core 60, upper iron shell 10 was coated on preceding glue core 60 outer ends with following iron-clad 20 before back glue core 30 was fixed on grab 50; 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 terminal 40 rear ends and back glue core 30.
