Description

Technical Field

[0001] This utility model belongs to the field of connectors, and in particular relates to a plastic through-wall terminal connector. Background Technology

[0002] Plastic through-wall terminal connectors are components used in the industrial field to enable circuit connections through panels or walls. Their core structure includes an insulating housing fixed to the panel and conductive terminals penetrating the housing. Traditional plastic through-wall terminal connectors have the following disadvantages: 1. The copper busbar is usually connected to the copper lug, which is prone to stripping and has poor structural strength; 2. Water leakage is likely at the connection point between the copper busbar and the housing; 3. The wiring at the rear end of the copper busbar has poor waterproofing performance and is difficult to drain. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a plastic through-wall terminal connector with good structural strength, resistance to stripping, and good waterproof performance.

[0004] To solve the above problems, the present invention adopts the following technical solution: a housing and a set of copper busbars integrally injection molded inside the housing. The rear end of the housing is provided with a set of wiring grooves. The rear end of the copper busbar is placed in the wiring grooves. The rear end of the copper busbar is riveted with a nut post through a riveting hole, and the lower end of the nut post is wrapped in the sheath of the housing. The connection between the copper busbar and the housing is provided with a glue-applying groove, and the glue-applying groove is provided with waterproof glue that seals with the housing.

[0005] The upper end of the nut post is provided with a flange, and the center of the flange is provided with a riveting post. The lower end of the riveting post is provided with a riveting tooth that is embedded in the riveting hole.

[0006] The copper busbar has a welded section formed by bending at its front end, and the end of the welded section is provided with a welding pin.

[0007] The rear end of the housing is provided with a dust cover, and the dust cover is provided with a water leakage hole.

[0008] A plastic pull rope connects the housing and the dust cover.

[0009] The plastic pull rope has a first connecting hole and a first conical connecting post at each end. The housing has a second conical connecting post that connects to the first connecting hole. The dust cover has a second connecting hole that connects to the first conical connecting post.

[0010] The housing is provided with a mounting flange, and a metal bushing is embedded in the mounting hole of the mounting flange.

[0011] The end face of the mounting flange is provided with a sealing ring.

[0012] The advantages of this plastic through-wall terminal connector are as follows: 1. By riveting a nut post to the rear end of the copper busbar and wrapping the nut post inside the sheath, the wiring is easy to strip, the structural strength is poor, and the waterproof performance is better; 2. By setting a glue-brushing groove at the connection between the copper busbar and the shell, and then setting waterproof glue in the glue-brushing groove, the waterproof performance can be greatly improved.

[0013] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0015] Reference Figures 1-7 As shown, the plastic through-wall terminal connector of this utility model includes a housing 1 and a set of copper busbars 2 integrally injection molded into the housing 1. A set of wiring grooves 3 is provided at the rear end of the housing 1, and the rear end of the copper busbars 2 is placed within the wiring grooves 3. A nut post 5 is riveted to the rear end of the copper busbars 2 through a riveting hole 4, and the lower end of the nut post 5 is wrapped within a sheath 6 of the housing 1. An adhesive application groove 7 is provided at the connection between the copper busbars 2 and the housing 1, and the adhesive application groove 7 contains a waterproof adhesive 8 that seals against the housing 1. The waterproof adhesive 8 can be silicone, polyurethane, epoxy resin, etc.

[0016] Preferably, the upper end of the nut post 5 is provided with a flange 9, and the center of the flange 9 is provided with a riveting post 10. The lower end of the riveting post 10 is provided with a riveting tooth 11 that is embedded in the riveting hole 4. When the riveting post 10 is riveted to the riveting hole 4, the riveting tooth 11 is embedded in the riveting hole 4 to improve the connection strength and prevent the nut post 5 from rotating.

[0017] Preferably, the front end of the copper busbar 2 is bent to form a welding portion 12, and the end of the welding portion 12 is provided with welding pins 13. By providing the welding pins 13, it is convenient to weld to the welding holes on the PCB board.
