Abstract

The utility model belongs to the technical field of electronic communication and particularly discloses an electrical connector. The electrical connector comprises terminals, a metal casing body and an insulator. A sliding press block is arranged at the upper part of the insulator. Convex strips which are buckled in a containable buckling slot of the insulator are arranged on the lower surface of the sliding press block. Buckling protruding structures are arranged on both sides of the sliding press block. The buckling protruding structures of the sliding press block and the insulator are an integrated structure. Buckling structures which can buckle the buckling protruding structures are arranged at the lower end of the inner side of the insulator. A number of terminals are arranged, and each terminal is made of a metal conductor and is a slip body whose front end bends upward. The electrical connector provided by the utility model has the advantages of few components, simple structure and no back cover and buckle.

Description

A kind of electric connector

Technical field

The utility model belongs to the electronic communication field, relates to particularly a kind of electric connector that need not the electronic communication product of bonnet and grab.

Background technology

The telecommunications products such as a lot of mobile phones, PDA all are provided with its charging or data transmission interface, and these electronic products all need its charging or electronic connector for data transmission.General wire comes splicing ear, electrically conducts to reach, the purposes such as short circuit, insulation, and the parts of its parts are more, and the body of parts is less, and manufacturing procedure is more in its manufacture process, and the combination installation difficulty strengthens.

In addition, the problem that comes off easily when preventing that electric connector from pegging graft, we arrange hook structure at electric connector usually, during grafting, grab can effectively prevent the electric connector problem that comes off, but has increased to a certain extent production cost and the manufacture difficulty of electric connector.

The utility model content

The purpose of this utility model is, for the existing above-mentioned deficiency of existing electric connector structure, provides a kind of bonnet and buckle of need not, the electric connector of the electronic communication product that parts are less, simple in structure.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is as follows:

A kind of electric connector, it comprises terminal, metal shell and insulator, also is provided with the sliding pressure piece on described insulator top; Being provided with at described sliding pressure piece lower surface can be at the raised line of the held draw-in groove of insulator; Be provided with the card lug structure in described sliding pressure piece both sides, card lug structure and the insulator of sliding pressure piece are integrated; But be provided with the buckle structure of buckle card lug structure in described insulator inside lower end; Described terminal has a plurality of, and terminal is that metallic conductor is made the slip body that front end is bent upwards.

Further, the upper and lower layer in described metal shell rear end is provided with the clamping sheet of outside projection, and the clamping sheet is provided with hole clipping, and the outer casing back left and right sides is provided with edge, the draw-in groove that described insulator is provided with and limit groove.

Further, described metal shell front end upper surface is provided with the metal buckle that raises up of integrated molding, and described metal card is buckled with two.

Further, described terminal front end is provided with bend, and the centre position is provided with two groups of salient points, and outermost terminal also has a spur structure.

The utility model beneficial effect is: the electric connector of this structure that the utility model provides, its all parts only include only 3 assemblies, and terminal is strip structure, and insulator and sliding pressure piece are integrated, can adopt Shooting Technique, manufacturing process is simple, during installation terminal is inserted the draw-in groove of insulator, and the sliding pressure piece is depressed, the card lug structure of sliding pressure piece and insulator notch are to snapping, metal shell is enclosed within on the insulator, its assembling is very easy again, greatly reduces the cost of product.

Embodiment

Describe the utility model in detail below in conjunction with accompanying drawing and specific implementation method, be used for explaining the utility model in schematic enforcement of the present utility model and explanation, but not as to restriction of the present utility model.

Shown in Fig. 1-6, electric connector provided by the utility model, it comprises an insulator 1 and shell 2, terminal 3.Described metal shell 2 front end upper surfaces are provided with the metal buckle that raises up 21 of integrated molding, and described metal buckle 22 has two.When electric connector was pegged graft, metal buckle 21 can be buckled on the grafting thing, makes it difficult drop-off.

The upper and lower layer in described metal shell 2 rear ends is provided with the clamping sheet 23 of outside projection, and clamping sheet 23 is provided with hole clipping 24, and metal shell 2 rear end left and right sides are provided with edge 22.The card that insulator 1 is provided with is established the limit groove of edge 22.

Also be provided with sliding pressure piece 11 on insulator 1 top, 11 of insulator 1 and sliding pressure pieces are provided with draw-in groove, sliding pressure piece 11 lower surfaces are provided with can be at the raised line 12 of the draw-in groove that is held into of insulator 1, sliding pressure piece 11 both sides are provided with card lug structure 13, card lug structure 13 and the insulator 1 of sliding pressure piece 11 are integrated, but insulator 1 inside lower end is provided with the buckle structure 14 of buckle card lug structure 13, terminal 3 can insert space between insulator 1 and the sliding pressure piece 11 by the draw-in groove of insulator 1, sliding pressure piece 11 can press down by external force, so that card lug structure 13 and insulator 1 fracture, and snap in the buckle structure 14 of insulator 1.Described terminal 3 has a plurality of, and terminal 3 is made the slip body that front end is bent upwards for metallic conductor.Terminal 3 front ends are provided with bend 31, and the centre position is provided with two groups of salient points 32, and the terminal rear end also has a spur structure 33.Bend 31 easily contacts with the terminal item of grafting thing, spur structure 33 convenient with terminal 3 and connecting line to welding.
