Abstract

The utility model discloses an electric connector, which is used for plugging with a corresponding plug with a metal shell, and comprises an insulation body, a plurality of conductive terminals and a metal shell. The conductive terminals are installed on the insulation body, the metal shell is used for wrapping the insulation body, a plugging chamber is formed by the insulation body and the metal shell, fastening grooves are arranged on two opposite sides of the rear end of the metal shell, and fastening bosses mutually matched with the fastening grooves are arranged on the insulation body. Therefore, rotation of the insulation body in the metal shell is effectively limited by means of fastening of the fastening grooves and the fastening bosses, so that the technical problem of deformation of male terminals and female terminals in plugging is avoided. On the other hand, the electric connector is simple in structure and low in cost.

Description

Electric connector

Technical field

The utility model relates to the electric connector of electronic device field, relates more specifically to a kind ofly prevent that insulating body from rotating cause public female end to plugging in the electric connector of distortion in metal shell.

Background technology

Continuous development along with electronic product; Between the various electronic products and the connection between the peripheral device more and more frequent; And realize being connected through various connectors (like USB connector, HDMI connector etc.) between electronic product and its peripheral device is a kind of very common connected mode, and therefore the frequency of utilization of various connectors also increases thereupon.Used so widely at electronic applications, so large-scale batch production is also changed into by original small-scale production gradually to the production of each connector in production firm.Make that the kind of connector is more and more, people use also more convenient.

Existing electric connector especially micro connector comprises insulating body, is installed in plurality of conductive terminals and the coated insulation body on the insulating body and forms the metal shell in grafting chamber with said insulating body; During use, the plug that will have metal shell is plugged in the said grafting chamber and gets final product.Yet limited by cost, be fixed together through matched in clearance between its insulating body and the metal shell, when plug inserts the grafting chamber and contacts said insulating body, usually can drive insulating body and in metal shell, select, cause public female end inserting distortion.

Therefore, a kind of electric connector that can overcome above-mentioned defective need be provided.

The utility model content

The purpose of the utility model is that the deficiency to above-mentioned prior art provides a kind of and prevents that insulating body from rotate cause public female end to plugging in the electric connector that is out of shape in metal shell.

For realizing above-mentioned purpose; The electric connector that the utility model provided; Be used for pegging graft with the plug that has metal shell accordingly; It comprises insulating body, be installed in plurality of conductive terminals and the coated insulation body on the insulating body and form the metal shell in grafting chamber with said insulating body, and the two opposite sides of the rear end of said metal shell offer the engaging groove, and said insulating body is provided with said and engages the engaging boss that groove cooperatively interacts.

To sum up; The two opposite sides of the rear end of metal shell described in the utility model offer the engaging groove; The two opposite sides of insulating body rear end outwards protrude out to form with said and engage the engaging boss that groove cooperatively interacts; Engaging through engaging groove and engaging boss has effectively limited the rotation of insulating body in metal shell, avoids the problem on deformation of public female end when inserting; On the other hand, adopt engaging groove and engaging boss to solve the problems of the technologies described above, simple in structure, cost is low.

Embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.

Referring to figs. 1 to Fig. 3; The utility model electric connector 100; Be used for pegging graft with the plug that has metal shell accordingly; It comprises insulating body 20, be installed in plurality of conductive terminals 30 and the coated insulation body 20 on the insulating body 20 and form the metal shell 10 in grafting chambeies 11 with said insulating body 20, and the two opposite sides of the rear end of said metal shell 10 offer engaging groove 12, and the two opposite sides of said insulating body 20 rear ends are provided with said and engage the engaging boss 22 that groove 12 cooperatively interacts.

With reference to figure 1 and Fig. 3, particularly, offer plurality of terminals groove 21 on the surface of said insulating body 20, said conducting terminal 30 is contained in the said terminal groove 21.

The preferably, referring to figs. 1 to Fig. 3, said engaging groove 12 be U-shaped groove and opening backward, said engaging boss 22 is the U-shaped boss that cooperates with it.Particularly, said engaging groove 12 runs through the shell wall of said metal shell 10.Cooperatively interacting of U-shaped groove and U-shaped boss further increased the connective stability between insulating body 20 and the metal shell 10, prevents that further insulating body 20 from rotating in metal shell 10.

The preferably, said engaging groove 12 has two and be distributed in the two opposite sides of said metal shell 10 at least at least.

The preferably, the front end of said metal shell 10 has outside bending and extends to form four guide wall 13, and mistake when said guide wall 13 prevents that plug from inserting grafting chamber 11 play the guiding role to the grafting of plug.

During assembling the utility model; With conducting terminal 30 injection mo(u)ldings to insulating body 20; This moment said metal shell 10 bonnet in opened condition, with the insulating body that conducting terminal 30 is installed 20 from the rear end of insulation crust 10 insert and and said metal shell 10 between form grafting chamber 11, the engaging boss 22 on the insulating body 20 stretches in the engaging groove 12 of said metal shell 10; Bonnet bending sealing with said metal shell 10 forms the utility model electric connector 100.To sum up, the utility model electric connector 100 is not only simple in structure, easy to process, and cost is low, and has effectively limited the rotation of insulating body 20 in metal shell 10, avoids the problem on deformation of public female end when inserting.
