Detailed Description
The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, the screw wire holder for the low-voltage electrical appliance comprises a holder body 1, a wire holder frame 2 and screws 3 are arranged in the holder body,
a first accommodating groove 11 is formed in the base body 1, the wiring frame is arranged in the first accommodating groove, and a connecting hole 21 in threaded connection with the screw is formed in the wiring frame;
the screw penetrates through the connecting hole and forms a crimping groove 22 for crimping a lead between the connecting hole and the inner wall of one side of the wire frame;
the screw comprises a nut 31 and a threaded rod 32,
the wire frame inner wall is equipped with flange 23, be equipped with on the flange and be used for the guiding hole 231 that the screw rod passed, the flange with base top inner wall forms and is used for the second holding tank 232 that the nut was placed.
When the screw rotates, the crimping groove formed between the bottom of the screw and the inner wall of the wire frame can be enlarged or reduced, when the wire needs to be compressed, the wire can be reduced for crimping, as an optimal scheme, the two sides of the wire frame are limited and cannot rotate, and therefore the wire frame can lift along with the rotation of the screw, and on the other hand, the wire frame is provided with a guide hole for guiding the screw when the screw lifts and prevents the screw from being inclined.
In this embodiment, as shown in the figure, the seat body includes an upper wall 12, and an operation hole 121 is formed on the upper wall, and the operation hole is communicated with the second receiving groove. This operation is used for a screwdriver insertion operation.
In this embodiment, as shown, the diameter of the access hole is smaller than the diameter of the nut. Preventing the screw from falling out.
In this embodiment, as shown in the figure, the inner wall of the first accommodating groove is in contact with the outer wall of the wire frame in the width direction.
In this embodiment, as shown in the figure, the inner wall of the first accommodating groove is provided with a convex rib 111 for contacting the outer walls of two sides of the wire connecting frame. The contact is the part of protruding muscle, reduces the frictional force that receives when the wire frame moves from top to bottom.
In this embodiment, as shown, the screw includes a threaded portion 321 and a smooth portion 322, the threaded portion being disposed above the smooth portion. After the wire frame rose the top, smooth portion and connecting hole flush fit, the wire frame of skidding this moment can not move along with it, increases life.
