Description

Technical Field

[0001] The utility model relates to the technical field of relay equipment, in particular to a relay frame with a symmetrical structure. Background Art

[0002] The relay skeleton is a component of the main structure of the relay. It is the basic framework for fixing the coils, contacts and other components inside the relay. The main function of the relay skeleton is to support the various components inside the relay to ensure that the various parts of the relay can work together stably during operation. The size and shape of the relay skeleton will vary depending on the type of relay and the application scenario. Generally speaking, the design of the relay skeleton needs to take into account the overall size of the relay, the installation method, and the coordination with other components. In actual applications, the size and shape of the relay skeleton will be customized according to the specifications and functional requirements of the relay;

[0003] Conventional relay skeletons are all asymmetric structures. If the winding direction changes, the winding tooling and jigs need to be readjusted or processed, which is not conducive to flexible deployment. Conventional relay skeletons are designed according to the functional structure of the relay. Due to the different internal structures of the relay, the skeleton shapes are different and irregular. For example, the design of the wire groove has only a starting end. When winding, the protection limit for the wire end will cause root damage if you are not careful during the manufacturing process, which poses a serious safety hazard. Therefore, the utility model proposes a relay skeleton with a symmetrical structure to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to propose a relay skeleton with a symmetrical structure, in which lead grooves and wire clamping grooves are symmetrically opened on the lead block, which is convenient for winding operations from different directions as needed during production, and convenient and flexible deployment of skeletons that do not require specific models, thereby effectively improving the compatibility of the relay skeleton. The wire ends are clamped on the clamping block by springs and wire clamping plates during winding, thereby realizing protection and limiting of the wire ends, effectively preventing damage to the wire ends during the manufacturing process.

[0006] A further improvement is that a wire blocking plate is fixedly provided at the bottom of the winding pile, and a through groove is opened in the winding pile.

[0007] A further improvement is that: a first reinforcement strip is fixedly provided on the winding pile symmetrically in the front and rear, and a second reinforcement strip is fixedly provided on the front side of the through groove.

DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0018] according to Figure 1 , Figure 2 , Figure 3 As shown, the present embodiment provides a relay skeleton with a symmetrical structure, including a winding pile 1, a symmetrical lead mechanism and a wire end protection mechanism, the symmetrical lead mechanism includes a lead block 2, a lead groove 3, a clamping groove 4, a clamping block 5, a clamping groove 6 and a lead pin 7, the winding pile 1 is fixed with a lead block 2 on the upper end, the lead block 2 is symmetrically provided with lead grooves 3 on the front side, the lead groove 3 is provided with two groups, the lead groove 3 is symmetrically provided with clamping grooves 4 below, the lead block 2 is symmetrically fixed with clamping blocks 5, the clamping blocks 5 are longitudinally provided with clamping grooves 6, and the clamping grooves 6 are provided with The sleeve is inserted with a lead pin 7, and a wire end protection mechanism is symmetrically provided on the clamping block 5. When in use, the copper wire is first wound around the lead pin 7 on one side and then clamped into the clamping groove 4 along the lead groove 3, and then the copper wire is wound around the winding pile 1. After winding, the end of the copper wire is clamped into the clamping groove 4 on the other side and guided by the lead groove 3 on the other side and then wound around the lead pin 7 on the other side. The symmetrical structure can also be used to wind in the opposite direction from the lead pin 7 on the other side, which solves the problem that the winding direction needs to be readjusted and processed when it changes, which is not conducive to flexible deployment.

[0019] A wire retaining plate 8 is fixedly provided at the bottom of the winding pile 1, and a through slot 9 is opened in the winding pile 1. The wire retaining plate 8 is located below the winding column to limit the copper wire to prevent the copper wire from slipping off, and the through slot 9 is convenient for inserting the iron core during installation.

[0020] A first reinforcing strip 10 is fixedly provided on the winding pile 1 symmetrically front and back, and a second reinforcing strip 11 is fixedly provided on the front side of the inner groove 9. The first reinforcing strip 10 increases the friction between the copper wire and the winding pile 1 when the copper wire is wound, and the second reinforcing strip 11 increases the friction between the inner wall of the groove 9 and the iron core.

[0021] The wire end protection mechanism includes a spring 12, a wire clamping plate 13 and a wire groove 14. The spring 12 is symmetrically fixed on the front side of the clamping block 5, and the spring 12 is located on both sides of the clamping groove 6. A wire clamping plate 13 is fixed on the front side of the spring 12, and a wire groove 14 is opened in the middle of the inner side of the wire clamping plate 13. Before the copper wire is wound around the lead pin 7, the wire clamping plate 13 is first pulled open and the copper wire is guided to pass through the wire groove 14 and then the wire clamping plate 13 is loosened. The elasticity of the spring 12 is used to clamp the copper wire between the wire clamping plate 13 and the clamping block 5 for fixation, which effectively prevents the problem of lack of protection limit at the end of the wire end, which is easy to cause wire end damage.

[0022] A mounting groove 15 is provided on the top of the lead block 2, a positioning block 16 is fixedly provided on the front side of the mounting groove 15, positioning columns 17 are symmetrically fixedly provided in the mounting groove 15, and there are multiple groups of positioning columns 17, which facilitates quick positioning of the relay frame during installation and improves installation efficiency.

[0023] Lead wire notches 18 are provided at four corners of the wire blocking plate 8 to facilitate positioning of the copper wire when the copper wire needs to be led out.

[0024] When the relay skeleton with a symmetrical structure is wound, the end of the copper wire is passed through the wire clamping plate and then wound on one side. After that, the wire is clamped into the wire clamping groove on one side under the guidance of the lead groove and then wound on the winding pile. After the winding is completed, the other end of the copper wire passes through the wire clamping plate on the clamping block on the other side and is limited and then wound on the lead pin on the other side. When adjustment is needed, the lead groove and the wire clamping groove with symmetrical structures are used to reversely wind in the same way, which is conducive to flexible deployment. The wire blocking plate cooperates with the clamping block to limit the position when the copper wire is wound. The first reinforcement strip increases the friction force when the copper wire is wound, and the second reinforcement strip increases the friction force when the iron core is inserted into the through groove, and at the same time improves the strength of the winding pile. When the clamping block is installed, it is quickly limited to a suitable installation position by the positioning block and the positioning column. The lead groove is convenient for preventing the copper wire from being blocked by the corners of the wire blocking plate when it is wound.
