Abstract

An electric connector used to insert and connect flexible circuit boards is disclosed. The utility model comprises an insulation body and a shielding board connected with the insulation body. Two sides of the insulating body respectively extend out a buckling hook by bending to the deviation direction from the shielding board. The end of the buckling hook extends out a buckling block and the end face of the buckling block is in an obtuse angle with the side of the shielding board. Two sides of the shielding board are provided with a holding groove respectively to match with the buckling block of the insulation block. As a result, the stable connection between the insulation body and the shielding board is realized.

Description

Electric connector

[technical field]

This creation is about a kind of electric connector, refers to a kind of electric connector for the grafting flexible PCB especially.

[background technology]

Follow flexible PCB (FPC) the continuous expansion of application in the industry cycle, supply the electric connector technology of grafting flexible PCB to reach its maturity, more and more higher to the stability and the accuracy requirement of electric connector engaging.Electric connector such as Fig. 4 and shown in Figure 5 commonly used, usually electric connector 1 ' is made up of insulating body 10 ', barricade 20 ' and clasp 30 ', and this insulating body 10 ' and barricade 20 ' can slide between the primary importance (with reference to Fig. 4) and the second place (with reference to Fig. 5).Yet this kind electric connector is when Fig. 4 position, and the barricade 20 ' of this electric connector 1 ' is by the end support of clasp 30 ', and the rigidity of clasp 30 ' end is relatively poor, very easily causes the barricade 20 ' of electric connector 1 ' to produce vibration; In addition, when Fig. 5 position, this barricade 20 ' sidewall can produce the moment towards insulating body 10 ' to the active force of buckle piece 34 ', thereby causes clasp 30 ' to produce from release trend.

[summary of the invention]

The purpose of this utility model is to provide a kind of simple in structure, insulating body to engage firm electric connector with barricade.

The purpose of this utility model is achieved through the following technical solutions: the utility model electric connector comprises that an insulating body and cooperates the barricade of winding on this insulating body.Wherein, a clasp is extended along the direction one bending that deviates from barricade respectively in the both sides of this insulating body, and the end of this clasp protrudes out a buckle piece outwardly, and the terminal surface of this buckle piece becomes an obtuse angle with the barricade side.The both sides of this barricade respectively are provided with a support slot, with the corresponding engaging of buckle piece of this insulating body, thereby realize that this insulating body is connected with the firm of barricade.

Owing to adopted above-mentioned embodiment, the utility model has the following advantages at least: utilize the clasp partially rigid that is connected with insulating body better, can avoid that barricade supports unstable so that the shortcoming of trembleing in the prior art; When electric connector is subjected to external force and makes insulating body and barricade that the trend that is separated be arranged, the buckle piece of this insulating body will be subjected to button hole inhibition power on the barricade, make the moment of clasp generation away from the insulating body direction, thereby reinforce the snap action of barricade and insulating body, play the effect of self-locking.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

See also Fig. 1 to Fig. 3, the utility model electric connector 1 comprises that an insulating body 10 and cooperates the barricade 20 of winding on this insulating body 10.

This insulating body 10 is provided with plurality of terminals (figure does not show), and a clasp 30 is extended along the direction one bending that deviates from barricade 20 respectively in the both sides of this insulating body 10, the end of this clasp 30 protrudes out a buckle piece 34 outwardly, and this buckle piece 34 has a terminal surface 34a who becomes an obtuse angle with these insulating body 10 sides; These insulating body 10 upper surfaces respectively are provided with a draw-in groove 12 near the place, two ends, and its lower surface respectively is provided with a gathering sill 14 near the place, two ends.

This barricade 20 is provided with a roof 20a, a diapire 20b and connects this roof 20a and the two side 20c of diapire 20b, so that these barricade 20 correspondences are set on this insulating body 10.Wherein this sidewall 20c offers a button hole 22 to buckle piece 34 that should insulating body 10, snaps in the location for buckle piece 34.The draw-in groove 12 of the corresponding insulating body 10 of this roof 20a stretches out one along the direction declivity that deviates from this insulating body 10 and holds shell fragment 24, and this holds shell fragment 24 and can cooperate in the draw-in groove 12 that is held in insulating body 10.The gathering sill 14 of the corresponding insulating body 10 of this diapire 20b is provided with a prerotation vane (figure does not show), and this prerotation vane can slide in the gathering sill 14 of insulating body 10 to realize the effect of guiding.

During assembling, at first insulating body 10 is aimed at the opening of barricade 20, the gathering sill 14 of insulating body 10 will be aimed at the prerotation vane of barricade 20 at this moment, rely on this gathering sill 14 and this insulating body 10 is inserted into smoothly reach primary importance (seeing also Fig. 2) in the barricade 20, the draw-in groove 12 of insulating body 10 fastens with the shell fragment 24 that holds of barricade 20 simultaneously, clasp 30 ends of this insulating body 10 and the buckle piece 34 on the clasp 30 will expose to outside the opening of barricade 20, this clasp 30 is connected with insulating body 10 and partly then is embedded in the barricade 20, and supports this barricade 20.Then, flexible PCB is inserted in this electric connector 1, continuing to promote this insulating body 10 slides to barricade 20, and the terminal surface 34a and the barricade 20 sidewall 20c that drive this buckle piece 34 interact, make clasp 30 produce the strain that after the moment of insulating body 10 inboards, produces to the inside, snap in correspondence in the button hole 22 of this barricade 20, thereby insulating body 10 is inserted in the barricade 20 smoothly reach the second place (consulting Fig. 3), flexible PCB will be stablized the state of electrically conducting that makes contact to terminal in the insulating body 10 simultaneously, promptly realize assembling.
