[0031] Please refer to Figures 1 to 6 , a wire-swinging proximity signaler includes a housing 1, a sensing element 2, a power supply board 3, a wire clip 4, a wire clamp 5, a spring 6, a spring cap 7, a cable 8, a tail attachment 9, and a plug 10.

[0032] The installation and potting schematic diagram of the internal sensing element and the power supply board is as Figure 3As shown. The sensing element 2 is potted in the bottom of the groove of the housing 1 with electronic sealant, and the sensing surface of the proximity signaler is the end surface of the housing 1; the power board 3 is installed along the housing slot, and after the power board 3 and the leads of the sensing element 2 are arranged, the power board 3 is potted inside the housing with electronic sealant. The potting structure can improve the insulation and sealing performance of the sensing element 2 and the power board 3 inside the proximity signaler, and improve the waterproof, moisture-proof and dust-proof performance of the entire device;

[0033] The potting method can prevent the main components and circuits inside the shell from being directly exposed, which can not only fix the internal sensing elements and power board, but also improve the insulation and sealing performance of the equipment, and improve the waterproof, moisture-proof and dust-proof performance of the equipment.

[0034] The lead wire inside the proximity signaler is wrapped with a wave-proof sleeve and a shielding net to form a cable 8;

[0035] Schematic diagram of shell welding structure Figure 4 As shown. Insert the line card 5 along the cable 8 into the engaging groove of the housing 1. The engaging step is as shown in FIG. Figure 4 As shown, the structural design of the bite step not only facilitates positioning before welding, but also improves the strength after welding. Finally, the line card 5 is fixed to the housing by welding. This connection method reduces the overlap surface between the housing and the line card, and realizes the miniaturization design of the equipment.

[0036] The schematic diagram of the spring welding structure of the cable part is as follows Figure 5 As shown. Pass the spring 6 along the cable 8 into the groove of the line card 5, and fix the spring 6 on the line card 5 by welding; pass the spring cap 7 along the cable 8 to the bottom of the groove just fitting the spring 6, and fix the spring cap 7 on the spring 6 by welding. The spring structure can increase the bending radius of the cable and effectively prevent the cable from contacting the sharp metal edge of the main structure of the proximity signal device and causing bending fatigue and breakage;

[0037] The welding connection method is used to fix the housing and the wire card, the wire card and the spring, and the spring and the spring cap. The application of the welding method can reduce the overlapping area of the structural parts, shorten the length dimension of the main part close to the signal device, and achieve the purpose of weight reduction and miniaturization design.

[0038] Cable compression structure diagram Figure 6 After the cable 8 is compressed by the wire clamp, it is fixed to the line card 5 by screws. The wire clamp acts as the tail accessory of the device and can prevent the cable from breaking from the lead welding point inside the device.

[0039] After passing the cable 8 through the tail attachment 9, it is fixed with screws and connected to the plug 10.
