Abstract

Originally practical to be related to a kind of drawing connector with escapement, including rubber shell, contact chip and rear cover, it is equipped with and the comparable isolated gate of number of poles in rubber shell, contact chip is equipped between adjacent isolated gate, the inside front ends of rubber shell are equipped with the parting bead for contact chip limit stops, the rear end of rubber shell forms access frame, rear cover is movable to be set in access frame, the two sides of rubber shell form the " Fang " shape of opening outwardly, the two sides of rubber shell are provided with the first sphenoid, the both ends of rear cover each extend over out folded arm, the end of folded arm is equipped with the second sphenoid with the cooperation clamping of the first sphenoid, folded arm, which is located at, is equipped with locking position close to the position of knob.When rear cover is inserted into access frame, the first sphenoid in rubber shell can be slid into locking position, and thus after " working position " of lock connector, the pressure tongue of rear cover will not be deviate from from access frame easily, greatly increase connector to the retentivity of winding displacement.

Description

A kind of drawing connector with escapement

Technical field

The utility model relates to a kind of drawing connector with escapement.

Background technique

Drawing connector is commonly called as drawer type connector, it generally comprises rubber shell, contact chip and rear cover, after cover and be provided with pressure Tongue, the rear end of rubber shell form access frame, in use, being put into winding displacement connecting pin in access frame, then, rear cover are inserted into and is accessed Frame locks winding displacement by the pressure tongue of rear cover and the pawl of contact chip.Frictional force with the aging of connector, between winding displacement and pressure tongue Reduce, at this point, may shake the electrical connection of winding displacement and contact chip pawl if applying pressure to winding displacement, lead to poor contact, very Deviate from connector to winding displacement.

Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of structures, simple, lockable " electrical connection " drawing connects Connect device.

In order to achieve the goal above, the utility model uses such a drawing connector with escapement, including Rubber shell, contact chip and rear cover, be equipped in the rubber shell with the comparable isolated gate of number of poles, be equipped with contact between adjacent isolated gate Piece, the inside front ends of the rubber shell are equipped with the parting bead for the contact chip limit stops, the rear end shape of the rubber shell At access frame, the rear cover is movable to be set in the access frame, and the two sides of the rubber shell, which are formed, to be open outwardly " Fang " shape, the two sides of the rubber shell are provided with the first sphenoid, and the both ends of the rear cover each extend over out folded arm, described The end of folded arm be equipped with the second sphenoid with the described first sphenoid cooperation clamping, the folded arm is located at close to knob Position be equipped with locking position.Compared with prior art, the advantageous effects of the invention are: through the above structure Setting, when rear cover is inserted into access frame, the first sphenoid in rubber shell can be slid into locking position, thus " the work of lock connector Make position " after, the pressure tongue of rear cover will not be deviate from from access frame easily, greatly increase connector to the retentivity of winding displacement.

Particularly, the locking position is countersink, and first sphenoid can slide into or pull out the countersink.

Particularly, the cross section of the countersink is in the trapezoidal shape to stand upside down.

The slope surface formation of design through the above structure, countersink extends out, and falls into or skid off locking convenient for the first sphenoid Position.

Detailed description of the invention

Fig. 1 is the partial sectional view of the utility model embodiment；

Fig. 2 is the partial enlarged view of the first lozenges and the cooperation of the second lozenges in the utility model embodiment.

In figure: 1, side sheath body；2, rear cover；21, the second sphenoid；22, position is engaged；23, it shakes hands；3, rubber shell；31, first wedge Body.

Specific embodiment

As shown in Fig. 1~2, a kind of drawing connector with escapement, including rubber shell 3, contact chip and rear cover 2, glue Be equipped in shell 3 with the comparable isolated gate of number of poles, be equipped with contact chip between adjacent isolated gate, the inside front ends of rubber shell 3, which are equipped with, to be used In the parting bead of contact chip limit stops, the rear end of rubber shell 3 forms access frame, and rear cover 2 is movable to be set in access frame, rubber shell 3 Two sides form opening " Fang " shape outwardly, the two sides of rubber shell 3 are provided with the first sphenoid 31, and the both ends of rear cover 2 are prolonged respectively Folded arm is stretched out, the end of folded arm is equipped with the second sphenoid 21 with the cooperation clamping of the first sphenoid 31, and folded arm is located at close to knob 23 position is equipped with locking position 22.

Locking position 22 is countersink, and the first sphenoid 31 can slide into or pull out countersink.The cross section of countersink is in handstand Trapezoidal shape.

Claims
