Description

Cord grip

Technical field

The utility model is a kind of cord grip, provides the cord grip that a kind of connector of powering connects wire rod.

Background technology

The application of electric connector is very extensive, the topmost purposes of electric connector is to connect wire rod, and the signal that wire rod transmitted passed to the device that it connects, in order to reach aforesaid purpose, must be provided with cord grip in the electric connector and can connect wire rod.

Existing cord grip, please cooperate with reference to Figure 6 and Figure 7, it has a hollow housing 40, the two ends of housing 40 are respectively equipped with one and insert mouthful 41 and one outlet 42, in being provided with a screw rod 43 adjacent to inserting mouthful 41 place's spiral shells, an end of screw rod 43 extends in the housing 40, is pivoted with a pivot block 44 in housing 40, pivot block 44 pushes against mutually with an end of screw rod 43, and the two ends of pivot block 44 are formed with an extrusion end 441 and one pushing and pressing end 442 respectively;

One conductive sheet 45 is to be inserted in the housing 40, and an end of conductive sheet 45 is formed with intermediate plate 451, and intermediate plate 451 is stretched out by outlet 42 places;

In addition the outer wall in housing 40 is installed with a shell fragment 46, and an end of shell fragment 46 extends in the housing 40, and compresses mutually with the pushing and pressing end 442 of pivot block 44 and to contact.

When using, a wire rod can be inserted by inserting mouthful 41 places, and the rotary screw 43 tight compressing wire rods of extrusion end 441 that force pivot block 44, again another wire rod is clamped on intermediate plate 451 places, so signal just can transmit via wire rod mutually mutually.

And desire is when taking out wire rod, and rotatable screw rod 43 makes the extrusion end 441 of pivot block 44 no longer oppress wire rod, and shell fragment 46 will promote pivot block 44 and makes it get back to initial position, so just wire rod can be taken out.

Yet existing cord grip still has its shortcoming to exist, have conductive sheet 45 and pivot block 44 in the housing 40 of cord grip, so must having, the space in the housing 40 can insert the space of rotating for wire rod and conductive sheet 45 with pivot block 44, so housing 40 must have certain volume, and the difference of electric connector internal cause effect, so must be provided with at least one cord grip in it, but present various telecommunication installation is to trend towards light, thin, short and little direction design and to make, so the volume of existing cord grip can't meet present demand.

The utility model content

This creator is because existing cord grip has the bigger shortcoming of volume, so redesign a kind of cord grip, it has a housing, housing is to be mutually combined by conductive cover and set casing to form, conductive cover can replace existing conductive sheet, plugs the space of conductive sheet so remove in the housing, so can dwindle the volume of cord grip, and then the overall volume of dwindling electric connector, be its practical novel purpose.

In order to reach aforesaid utility model purpose, technological means of the present utility model is to provide a kind of cord grip, and it has a conductive cover, and the one end is formed with intermediate plate, is formed with a breach in holding in addition of conductive cover;

One set casing, one end are provided with a screw, and screw place spiral shell is provided with a screw rod, and an end of screw rod extends in the set casing, is formed with a breach in set casing adjacent to the screwhole position place;

One pivot block, it is to be hubbed in the set casing, a side and the screw rod of pivot block are in contact with one another;

One spring shape body, it is the other end that is fixedly arranged on set casing, another side of an elastomeric end and pivot block pushes against mutually;

Conductive cover and set casing are to mutually combine fixingly, and one inserts mouthful, and being mutually combined by the breach of the breach of set casing and conductive cover forms.

Another technical scheme of the present utility model is to provide a kind of cord grip, it has a housing, one end of housing is provided with screw, spiral shell is provided with screw rod in the screw place, one end of screw rod extends in the housing, be formed with the insertion mouth at housing adjacent to the housing place, and be pivoted with a pivot block in housing, a side and the screw rod of pivot block are in contact with one another;

The other end of housing is formed with fixed edge, and the place is installed with shell fragment in fixed edge, and an end of shell fragment and another side of pivot block are in contact with one another;

Other is formed with intermediate plate in the side that housing is formed with an end of fixed edge.

When wire rod inserted in the housing by the insertion mouth, screw rod can promote pivot block, makes an end of pivot block closely oppress wire rod, again another wire rod is clamped on the intermediate plate place, and so signal just can transmit via wire rod mutually mutually.

And desire can make screw rod no longer promote pivot block when taking out wire rod in the housing, elastomer can make pivot block get back to initial position, so just wire rod can be taken out.

And conductive cover can replace existing conductive sheet, insert the required space of existing conductive sheet so can remove in the housing, therefore the overall volume utmost point of housing can reduce, and then dwindles the overall volume of electric connector, to meet existing light, thin, short and little telecommunication installation.
