Detailed Description

The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

In the present utility model, unless otherwise indicated, the terms "inner, outer, end" and the like are used merely to denote the orientation of the term in a conventional use state or are commonly understood by those skilled in the art, and should not be construed as limiting the term.

The utility model provides a wire holder, which comprises a copper bar 1 and a plastic shell 2 wrapped outside the copper bar 1, wherein the plastic shell 2 can protect the copper bar 1 and prevent the copper bar 1 from bending, deforming, breaking or corroding, and can play an insulating role and prevent the copper bar 1 from leaking electricity from a non-terminal. The plastic shell 2 is integrally provided with a sealing plate 3, a plurality of mounting holes are formed in the sealing plate 3, and a steel sleeve 4 is connected in the mounting holes in an injection molding mode.

The both ends of copper bar 1 are connected with the automatically controlled end and the motor of new forms of energy respectively to make automatically controlled end can control the motor, the connection terminal passes the steel bushing 4 fixed mounting in the mounting hole on the frame through the bolt, and steel bushing 4 moulds plastics and connects in the mounting hole, and an organic whole sets up, and the centre is seamless, and joint strength is high, can make the connection terminal installation more firm.

The injection molding connection method of the steel sleeve 4 comprises the following steps: and putting the steel sleeve 4 on a mould positioning column, starting the slide block for pushing, and forming the steel sleeve 4 together with plastic during injection molding. The steel sleeve 4 is made of SU303 stainless steel, and the plastic is Suwei 1933.

The plastic shell 2 is also provided with a glue reducing groove 9, and too thick plastic can cause shrinkage deformation of the product after injection molding. The rectangular clamping groove 10 on the plastic shell 2 is used for supporting and positioning the copper bar 1, the copper bar 1 is supported after being put into a die, the copper bar 1 is clamped when the dies are combined, and the copper bar is not deviated during injection molding.

Preferably, the sealing plate 3 is arranged perpendicular to the plastic shell 2, so that interference is avoided. For example, when the wire holder is mounted on the frame, if the sealing plate 3 is not perpendicular to the plastic shell 2, the bolt may collide with the plastic shell 2 after passing through the steel sleeve 4, and thus cannot be mounted.

Preferably, the plastic shell 2 is connected with the binding post 5 at the both ends injection molding of copper bar 1, and binding post 5 is wrapped up in by plastic shell 2 promptly, avoids droing. And when the electric control end or the motor is connected, the lead copper sheet is attached to the end head of the copper bar 1, then the screw is in threaded connection with the wiring terminal 5, and the lead copper sheet of the electric control end or the motor is tightly pressed together with the end head of the copper bar 1. The wire of the electric control terminal or the motor can also be a round wire.
