Detailed implementation

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Refer to Figure 2-11 , a sensor convenient for assembly, including a coil bracket, a terminal 8 fixed on the coil bracket, a capacitor 9 electrically connected to the terminal 8, and a coil wound around the coil bracket and electrically connected to the terminal 8. The coil bracket includes a support base 1 and a terminal support 7. The terminal support 7 is fixedly connected to the support base 1 in a sleeved manner. The terminal 8 and the capacitor 9 are fixed together with the terminal support 7. The terminal 8 is fixed on the terminal support 7 in a plug-in manner. A wire winding groove 4 is opened at the bottom end of the terminal support 7, and the coil is wound around the wire winding groove 4.

[0029] The coil bracket is provided in two parts, namely the support base 1 and the terminal support 7. After connecting the terminal 8, the capacitor 9, and the coil to the terminal support 7, then the terminal support 7 is fixed to the support base 1. The terminal 8 is fixed on the terminal support 7 in a plug-in manner, which reduces the difficulty for workers to install the terminal. The terminal support 7 is a single-piece structure, which is more convenient for installing the capacitor 9, greatly improves the assembly efficiency, and can realize automatic assembly at the same time.

[0030] Refer to Figure 2-4 , the support base 1 includes a base platform, and a vertically arranged support cylinder 6 is integrally formed on the top surface of the base platform. A through hole 11 is opened on the terminal support 7, and the terminal support 7 is sleeved on the support cylinder 6 through the through hole 11. When assembling the terminal support 7, the terminal support 7 is directly sleeved on the support cylinder 6. In order to make the connection more firm, a plurality of limiting protrusions 3 are integrally formed on the top surface of the base platform. The bottom end of the terminal support 7 is circumferentially provided with extending support legs 2 whose number and positions correspond to those of the limiting protrusions 3. The limiting protrusions 3 penetrate through the extending support legs 2, and the two are fixed together by welding, so that the terminal support 7 is fixed more firmly through the extended support legs.

[0031] Refer to Figure 4-6, two wiring slots 5 are provided on the terminal support 7. The terminal support 7 is provided with a second extension part 16 and a first extension part 15. The second extension part 16 is placed above the first extension part 15, and the second extension part 16 and the first extension part 15 are arranged in a staggered manner. An L-shaped wiring slot 5 is provided between the second extension part 16 and the first extension part 15. The head and tail of the coil pass through the wiring slot 5 and are electrically connected to the wiring pins 10 of the terminal 8. A extending support leg 2 is provided directly below each wiring slot 5.

[0032] Reference Figure 1 , the wiring slot 5 provided on the traditional coil support is a simple opening structure. When winding the coil with this structure, it is easy to cause the enameled wire to cross and twist. In this device, the second extension part 16 and the first extension part 15 are arranged in a staggered manner. Through the second extension part 16 and the first extension part 15, the wiring slot 5 is in an L shape. The enameled wire is led out from the wiring pin 10, passes through the wiring slot 5 and then winds around the winding slot 4. After the coil winding is completed, the end is wound up. When winding up, it bypasses from the other wiring slot 5, and the tail of the enameled wire is connected to its corresponding wiring pin 10 together, effectively avoiding the situation of cross twisting. The enameled wire is designed in a hidden way. Since the second extension part 16 and the first extension part 15 are arranged in a staggered manner, the wiring mode of the enameled wire cannot be viewed from directly above. A extending support leg 2 is provided directly below each wiring slot 5, and the wiring mode of the enameled wire cannot be viewed from directly below either.

[0033] The extending support leg 2 and the terminal 8 are respectively placed on both sides of the support cylinder 6, making the installation of the device more convenient.

[0034] Both the bottom ends of the support cylinder 6 and the limiting protrusion 3 are provided with bosses 13. The design of the bosses enables the terminal support 7 to be raised during installation, with good flexibility.

[0035] The terminal 8 is composed of a horizontally formed part and a bent part formed integrally. The terminal 8 is in an L-shaped structure. A convex point 14 is provided on the top surface of the horizontally formed part. The horizontally formed part of the terminal 8 is clamped and limited to the terminal support 7 through the convex point 14 and the bent part. The terminal is clamped to the terminal support 7 more firmly and is also very convenient to assemble at the same time.

[0036] A wiring pin 10 is provided on the side of the terminal 8. A reinforcing rib 12 is provided on the wiring pin 10. The reinforcing rib 12 is formed by stamping. Since the wiring pin 10 itself is very thin and easy to be damaged, a reinforcing rib is stamped on the wiring pin 10 to make the wiring pin 10 have better bending resistance.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, concept, and design obtained by those skilled in the art in the technical scope disclosed by the present invention through equivalent replacement or change based on the technical solution and inventive concept of the present invention should be covered within the protection scope of the present invention.
