Description

Technical Field

[0001] The utility model belongs to the technical field of motor sensor design, and in particular relates to a shielding and sealing structure of a lead-out line terminal of a product. Background Art

[0002] The sealing and electromagnetic shielding of the cable lead wires of motors and sensor sockets are issues that need to be considered in many product designs. Since the cable lead wires are soft and elastic, it is difficult to seal and fix them, so the lead wire outlet end is often sealed by injecting sealant.

[0003] However, the sealant injection method requires a space of a certain size. Due to structural limitations, some products do not have sufficient space to design the sealant injection structure. Utility Model Content

[0004] In order to solve the problem that the method of injecting sealant in the prior art requires a space of a certain size, and some products are limited by the structure and do not have enough space to design the injection structure, the utility model provides a shielding and sealing structure for the lead-out line of the product, which adopts a heat shrink tube for sealing and a wave-proof sleeve for shielding. The wave-proof sleeve is mounted on the outer surface of the lead-out seat with a shoulder and fixed with a stainless steel tie and a silver-plated copper wire. The shoulder design of the lead-out seat can solve the problem of the wave-proof sleeve falling off. The stainless steel tie and the silver-plated copper wire have good conductivity and can better ground and shield electromagnetic interference. The wave-proof sleeve is equipped with a heat shrink tube, and sealant is applied between the heat shrink tube and the end face of the shell, which can prevent the wave-proof sleeve from being damaged and causing the lead-out line to be exposed, and external force can be applied to the heat shrink tube and the wave-proof sleeve to protect the cable lead-out line from external force, and can also effectively solve the problem of sealing the cable lead-out line outlet. The technical scheme is as follows:

[0005] In the first aspect, a shielding and sealing structure of a lead-out terminal of a product is provided, comprising: a lead-out seat 2, a wave-proof sleeve 4, a stainless steel tie 5, a silver-plated copper wire 6, and a heat shrink tube 8, wherein:

[0006] A boss is provided at the lower end of the lead-out seat 2, and a recessed structure that is engaged with the boss is provided at the outlet end of the shell 1. The lower end of the lead-out seat 2 is fixedly connected to the outlet end of the shell 1, and the wave-proof sleeve 4 is sleeved on the lead-out seat 2 and the outlet end of the shell 1. The stainless steel cable tie 5 is sleeved on the outside of the wave-proof sleeve 4. The bottom end of the wave-proof sleeve 4 is a flanged structure, and there is a preset distance L between the bottom end of the wave-proof sleeve 4 and the root of the outlet end of the shell 1. Sealant 7 is coated between the bottom end of the wave-proof sleeve 4 and the root of the outlet end of the shell 1, and silver-plated copper wire 6 is wrapped around the outside of the flanged structure at the bottom end of the wave-proof sleeve 4. The heat shrink tube 8 is sleeved on the outside of the shell 1 coated with sealant 7, and the length of the heat shrink tube 8 is greater than the preset distance L, and L is greater than 0 and less than or equal to 5 mm; the lead-out wire 3 is led out from the outlet end 1a of the shell 1 through the outlet hole 2b of the lead-out seat 2.

[0007] The contact point between the heat shrink tube 8 and the housing 1 is coated with sealant 7 .

[0008] The outer diameters of the outlet terminal 1a of the housing 1 and the outlet hole 2b of the lead-out seat 2 are both 10mm. The upper end of the lead-out seat 2 is provided with a convex shoulder, the outer diameter of the convex shoulder is greater than 10mm, and the height of the convex shoulder is 1mm.

[0009] The convex shoulder of the lead-out seat 2 has a fillet of R0.3 around it.

[0010] The outer diameter of the boss of the lead-out seat 2 is 12 mm.

[0011] The lower end of the lead-out socket 2 is welded to the lead-out end of the housing 1 .

[0012] The beneficial effects of the utility model are at least:

[0013] The structure adopts heat shrink tube sealing and wave-proof sleeve shielding. The wave-proof sleeve is installed on the outer surface of the lead-out seat with a shoulder and fixed with stainless steel cable ties and silver-plated copper wire.
