Description

Technical Field

[0001] The utility model belongs to the technical field of relay skeletons, and particularly relates to a relay skeleton for preventing enameled wire from being cut. Background Art

[0002] A relay skeleton is a bracket for winding coils. Relay skeletons are usually made of plastic, bakelite or ceramic and can be made into different shapes according to actual needs. When in use, enameled wire or cotton-covered wire is wound around the skeleton. In the existing relay skeletons, after the enameled wire or cotton-covered wire is wound, it will loosen and run out of the defined range, and at the same time, there is a fatal risk that the enameled wire will break due to scratching during subsequent assembly; moreover, in the existing relay skeletons, the enameled wire will be cut by the sharp edges of parts during subsequent assembly.

[0003] The patent with the application number 202420123383.0 discloses a relay skeleton for preventing enameled wire from being cut, including a skeleton assembly. The skeleton assembly is composed of a winding square frame, a left end cover body and a right end cover body. The right end cover body is integrally injection-molded at the end of the winding square frame. A third wire groove is arranged on the surface of one side of the right end cover body, and a second wire groove is arranged on the surface of the right end cover body above the third wire groove. A first wire groove is arranged at the top of the right end cover body, and the first wire groove, the second wire groove and the third wire groove are combined with the side line of the right end cover body and are all designed with an arc R surface.

[0004] The above technical solution uses the arc R surface design of the first wire groove, the second wire groove and the third wire groove combined with the side line of the right end cover body to prevent the enameled wire from being cut by the sharp edges of parts. However, after processing, mutual extrusion and collision between multiple relays will still cause damage to the surface of the enameled wire, resulting in a short circuit situation, and the protection effect on the enameled wire is poor.

[0008] To solve the above technical problems, the present utility model provides a relay skeleton for preventing enameled wire from being cut. The relay skeleton for preventing enameled wire from being cut includes a winding frame and rigid cover plates fixed at both ends of the winding frame. Flexible rubber cover plates are symmetrically fixed at the central position of the winding frame. A protective component is detachably installed between the two flexible rubber cover plates. The protective component includes a first protective cover and a second protective cover sleeved on the winding frame.

[0009] When using this technical solution, by symmetrically fixing flexible rubber cover plates at the central position of the winding frame, the flexible rubber cover plates position the winding of the enameled wire. At the same time, after the enameled wire is wound, it is connected to the winding terminals through the arc-shaped grooves on the flexible rubber cover plates. Since the flexible rubber cover plates have elasticity, it prevents the enameled wire from being cut by the sharp edges of the parts. By providing a protective component on the winding frame, after winding, the first protective cover and the second protective cover constituting the protective component are installed on the winding frame. The elastic plates in the grooves at both ends of the second protective cover are inserted into the through grooves on the first connecting frame, and the protruding parts on the elastic plates are engaged with the positioning grooves, so that the first protective cover and the second protective cover are fixed to each other. After being fixed, the enameled wire head is embedded in the wire passing grooves on the protruding parts. The surface of the wound enameled wire is protected by the protective component, avoiding the situation that the enameled wire is damaged by collision and improving the protection effect of the enameled wire.

[0010] Preferably, support plates are fixed on both sides of the inner wall of the winding frame, and arc-shaped grooves are symmetrically formed at both ends of the rigid cover plates and the flexible rubber cover plates.

[0011] Further, winding terminals are fixed on both sides of the bottom end surface of the winding frame, and a plurality of connecting pins are arranged at the bottom end of the winding terminals.

[0012] Furthermore, protruding parts that fit and sleeve on the winding frame are fixed at both ends of the first protective cover and the second protective cover, and a plurality of wire passing grooves are formed on the protruding parts.

[0013] Furthermore, grooves are formed at both ends of the first protective cover, and the elastic plates are fixedly connected to the central position of the inner wall of the grooves.

[0014] Furthermore, the elastic plates protrude from the side wall of the first protective cover, and the elastic plates are slidably inserted into the through grooves.

[0015] Furthermore, a positioning part with a trapezoidal structure is fixed on the outer wall of the elastic plate, and the positioning part is fitted and inserted into the positioning groove.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, flexible rubber covers are symmetrically fixed at the central position of the wire winding frame. The flexible rubber covers position the winding of the enameled wire. At the same time, after the enameled wire is wound, it is connected to the wire winding terminal through the arc-shaped grooves on the flexible rubber covers. Since the flexible rubber covers have elasticity, it prevents the enameled wire from being cut by the sharp edges of the parts.

[0019] By providing a protection component on the wire winding frame, after winding, the first protection cover and the second protection cover that make up the protection component are installed on the wire winding frame.
