Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying equipment, in particular to a novel TPA structure. Background Art

[0002] In electronic devices, connectors play a key role in transmitting signals and power. In order to ensure that connectors can reliably perform their functions, various designs and technical means are needed to ensure the fixity of their positions and the stability of terminal connections. The terminal secondary locking structure (TPA) is an important performance to ensure the reliability of connectors.

[0003] The industrial hybrid connectors currently on the market are mainly quick-lock products. Quick-lock products are easy and quick to install, which can improve the installation efficiency of end users and facilitate wiring. The power terminal and the socket rubber core are fixed by 180-degree insertion, and then the wire is bent 90 degrees. The terminal and the rubber core are fixed by hanging, and the holding force is not good enough. There is tension after the wire is bent, and there is a quality risk of the terminal falling off. Utility Model Content

[0004] The purpose of the utility model is to provide a novel TPA structure in order to solve the above problems.

[0005] The technical solution adopted by the utility model is as follows: a new TPA structure, comprising:

[0006] The rubber core has a plurality of mounting cavities in the middle of one side of the upper surface, and fixing cavities are provided on both the left and right sides of one side of the upper surface;

[0007] A power terminal is inserted into the installation cavity, and a locking groove is provided in the middle of the power terminal;

[0008] The TPA has a buckle connected to the inside of the fixed cavity, and the left and right sides of the upper surface of the TPA are integrally provided with extended ends, and the extended ends are snap-connected to the inside of the locking groove.

[0009] Through the above technical solution, the power terminal is first inserted into the rubber core, and there is a cantilever on the rubber core to buckle the power terminal. The existing products on the market only have this structure to fix the terminal, and the holding force is very small. By setting the TPA, it is placed in the fixed cavity and pushed inward at the same time. The extended end of the TPA clamps the locking groove of the power terminal to limit the power terminal, so that the power terminal is fixed on the TPA, forming a secondary lock, locking the terminal position, and greatly increasing the holding force.

[0010] In a preferred embodiment, toothed grooves are provided on both the left and right sides of the TPA.

[0011] Through the above technical solution, the stability of TPA and the rubber core is improved by providing the toothed grooves.

[0012] In a preferred embodiment, a boss is integrally provided on the upper surface of the TPA away from the protruding end.

[0013] Through the above technical solution, the boss is provided to facilitate quick pushing of the TPA, and the installation is convenient for disassembly.

[0014] In a preferred embodiment, a cantilever is arranged inside the fixing cavity.

[0015] Through the above technical solution, the power terminal is preliminarily fixed by setting the cantilever.

[0016] In a preferred embodiment, the TPA is injection molded.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: the utility model proposes a new TPA structure.

[0018] First, insert the power terminal into the rubber core. There is a cantilever on the rubber core to buckle the power terminal. Existing products on the market only have this structure to fix the terminal, and the holding force is very small. By setting the TPA, put it into the fixed cavity and push it inward at the same time. The extended end of the TPA clamps the locking groove of the power terminal to limit the power terminal, so that the power terminal is fixed on the TPA, forming a secondary lock, locking the terminal position, and greatly increasing the holding force.

[0028] A novel TPA structure, comprising:

[0029] The rubber core 1 has a plurality of mounting cavities 11 disposed in the middle of one side of the upper surface, and a fixing cavity 12 is disposed on both the left and right sides of one side of the upper surface, and a cantilever is disposed inside the fixing cavity 12. The power terminal 3 is plugged into the mounting cavity 11, and the power terminal 3 is preliminarily fixed by disposing the cantilever, and a locking groove 31 is disposed in the middle of the power terminal 3;

[0030] TPA2, whose buckle is connected to the inside of the fixed cavity 12, is injection molded, and is provided with toothed grooves on both sides of TPA2. The toothed grooves are provided to improve the stability of TPA2 and the rubber core 1. Both sides of the upper surface of TPA2 are provided with protruding ends 21 in an integrated manner, and a boss is provided in an integrated manner on the side of the upper surface of TPA2 away from the protruding end 21. The boss is provided to facilitate rapid pushing of TPA2, and is easy to install and disassemble. The protruding end 21 is clamped in the locking groove 31. By setting TPA2, it is placed in the fixed cavity 12 and pushed inward at the same time. The protruding end 21 of TPA2 clamps the locking groove 31 of the power terminal 3 to limit the power terminal 3, so that the power terminal 3 is fixed on TPA2, forming a secondary lock, locking the terminal position, and greatly increasing the holding force.
