Abstract
Description
Technical Field
[0001] The utility model relates to the field of motors, in particular to a stepping motor. Background Art
[0002] The leads of conventional motors are usually directly welded on the circuit board. When the leads are pulled back and forth by external forces, the connection between the wire core and the circuit board is easily torn off. In order to avoid wire breakage, the current method is to reinforce them with glue, which is costly and difficult to operate, and the glue takes a long time to completely dry and solidify. Utility Model Content
[0003] In view of the above situation, the purpose of the utility model is to provide a stepping motor with a wire protection box, which increases the pulling strength of the lead wire.
[0004] The stepper motor specifically adopts the following scheme:
[0005] A housing is provided, and a wire protection box is installed on the housing. The wire protection box is provided with a mounting plane, and a wire groove is provided on the mounting plane. One end of the mounting plane is provided with a wire outlet vertically connected thereto. The lead wire is laid along the mounting plane, passes through and is stuck in the wire groove, and is bent from the wire outlet and then passes out. Through the design of the wire protection box, after assembling other parts inside the housing, the lead wire is stuck in the wire groove. When the lead wire is pulled by external force, because the lead wire has a bend, a friction force will be generated at the turning place. In addition to the friction force of the wire groove, the lead wire is difficult to be pulled, thereby greatly increasing the pulling strength of the lead wire and avoiding the breakage of the wire core connection.
[0006] Furthermore, in order to reduce manufacturing costs and to rationally utilize space, the utility model opens a window on the side of the casing, and the wire protection box has side wings that match and are fixed to the two sides of the window and side walls connecting the two side wings. At the same time, a bottom wall for closure is provided at the bottom of the side wall. The top of the wire protection box is open to facilitate the lead wire to pass through, the installation plane is formed in the side wall, and the wire outlet is formed at the top of the side wall. With this design, after assembling other parts inside the casing, the two side wings of the wire protection box are connected to the two sides of the window to close the casing. Before installing the wire protection box, the lead wire needs to be straightened and connected to the wire trough, and then bent and passed through from the wire outlet after the wire protection box is installed.
[0007] Furthermore, the side wings have at least two lock buckles with a staggered design. The side wings of the wire protection box can interact with each other from both sides of the window through the staggered lock buckles to produce a plug-in lock, so that the side wings can be conveniently and firmly connected to the window.
[0008] Furthermore, the top of the casing is open to facilitate the installation of internal parts, and the wire protection box can be directly inserted into the window from the top of the casing downward; accordingly, a cover plate is provided on the top of the casing, and its function is to close the casing.
[0009] Compared with the prior art, the utility model can increase the pulling strength of the lead wire through the wire protection box to prevent the wire core connection from being broken due to stress. BRIEF DESCRIPTION OF THE DRAWINGS
