Description

Technical Field

[0001] This utility model relates to the field of automotive relay technology, specifically to a winding and fixing structure for an automotive relay. Background Technology

[0002] An automotive relay is an automatic switch that uses a small current to control a large current. It is widely used in automotive circuit control and plays a role in safety protection, circuit switching, and automatic adjustment. An automotive relay is mainly composed of an iron core, coil, armature, contact springs, etc. Its working principle is that the current in the coil generates a magnetic field, which causes the armature to be attracted to the iron core, pushing the contacts to close or open, thereby realizing the function of circuit conduction or disconnection.

[0003] The existing winding and fixing structure of automotive relays cannot be effectively positioned during winding, lacking a corresponding positioning structure. As a result, when the coil on the pin breaks, the whole structure will become loose, lacking a secondary positioning and protection structure.

[0004] Therefore, we propose a novel winding and fixing structure for automotive relays to solve the above-mentioned technical problems. Utility Model Content

[0032] Example 1

[0033] This embodiment provides a technical solution: a winding fixing structure for an automotive relay, such as... Figures 1-5 As shown, it includes a winding coil assembly, a coil body 2, a positioning and mounting sleeve, a pin body, a lead body 5, and an abutment positioning mechanism.

[0034] The coil body 2 is wound and installed on the coil winding assembly, and can be wound and placed. The positioning and mounting sleeve is installed and connected to the lower end of the coil winding assembly on both sides. The wire of the coil body 2 can be effectively guided and wound through the positioning and mounting sleeve. The pin body is installed and fixed between the coil winding assembly and the positioning and mounting sleeve, so that the coil winding assembly and the positioning and mounting sleeve can be installed and placed accordingly. The front end of the pin body can effectively wind the coil. The pin body 5 is installed and fixed on the lower end of the positioning and mounting sleeve, and can be installed and connected accordingly. The abutting and positioning mechanism is installed and fixed on the positioning and mounting sleeve. The abutting and positioning mechanism can effectively abut the coil wire on the positioning and mounting sleeve, so as to effectively fix it and prevent the coil body 2 wire from loosening and scattering due to the breakage of the pin body.

[0035] The positioning and mounting sleeves are fitted onto the lower ends of the winding coil assembly on both sides, allowing for corresponding installation and placement.

[0036] The winding coil assembly includes a winding roller 11, and winding frames 1 are installed at both ends of the winding roller 11. The winding frames 1 can effectively limit the winding roller 11 to rotate in a positioning manner. A bottom mounting cavity 12 is opened on the inner side of the lower end of the winding frame 1. The winding frame 1 is installed and connected to the positioning mounting sleeve through the bottom mounting cavity 12, so that it can be fitted and installed accordingly.

[0037] like Figures 1-3 As shown, the contact positioning mechanism includes an arc-shaped clamping plate 6. A rotating disc 61 is rotatably mounted on the inner end of the arc-shaped clamping plate 6. A metal screw 62 is mounted on the rotating disc 61 through the arc-shaped clamping plate 6. The metal screw 62 is threadedly connected to the mounting sleeve housing 4. When the metal screw 62 rotates inward on the mounting sleeve housing 4, the metal screw 62 drives the rotating disc 61 to rotate inward. The rotating disc 61 then drives the arc-shaped clamping plate 6 to rotate inward. The arc-shaped clamping plate 6 then abuts against and fixes the coil wire in the arc-shaped wire groove 41 at the front end of the mounting sleeve housing 4, preventing the coil body 2 wire from loosening and scattering due to the breakage of the pin body. A bottom nut 63 is installed on the outer end of the metal screw 62, which makes it easy for personnel to hold and rotate it.

[0038] There are two contact positioning mechanisms installed, and they are symmetrically installed on the positioning mounting sleeve, so that the contact positioning mechanisms can rotate and contact the positioning mounting sleeve.

[0039] During use, the pin body is installed and fixed between the winding coil assembly and the positioning mounting sleeve, so that the winding coil assembly and the positioning mounting sleeve can be installed and placed accordingly. The front end of the pin body can effectively wind the coil. The pin body 5 is installed and fixed on the lower end of the positioning mounting sleeve, so that it can be installed and connected accordingly. The abutting positioning mechanism can effectively abut against the coil wire on the positioning mounting sleeve, thereby effectively fixing it and preventing the coil body 2 wire from loosening and scattering due to the breakage of the pin body.

Figure 1 , Figure 4 and Figure 5 As shown, to further better realize this utility model, the following configuration is adopted: the pin body includes a pin housing 3, which is inserted into the connection between the winding coil group and the positioning mounting sleeve so that they can be installed accordingly. The outer wall of the front end of the pin housing 3 is provided with a back groove 31, which makes it easy to wind the coil wire. The middle of the front end of the pin housing 3 is provided with an L-shaped groove 32, and the coil wire passes through the shape of the L-shaped groove 32, so that it can be fixed with the coil wire at the back groove 31.

[0043] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 and Figure 2 As shown, to further better realize this utility model, the following configuration is specifically adopted: the positioning and mounting sleeve includes a mounting sleeve shell 4, and a corresponding mounting groove 43 is opened in the middle of the upper end of the mounting sleeve shell 4, so that the winding coil group can be correspondingly sleeved and installed. A square hole insert plate 42 is installed on the inner side of the corresponding mounting groove 43 on the mounting sleeve shell 4. The square hole insert plate 42 allows the pin shell 3 to be inserted and positioned through the internal hole. An arc-shaped wire groove 41 is opened on the inner side of the front end of the mounting sleeve shell 4, so that the wire source of the coil body 2 can be guided and placed. An abutting positioning mechanism is installed on the inner side of the arc-shaped wire groove 41 on the mounting sleeve shell 4, which can abut the wire source wire of the arc-shaped wire groove 41.
