Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to an electrical connecting component and a process thereof. Background Art

[0002] The connection components of the existing technology generally include insulating seats and terminal seats that are fixed by interference through techniques such as clamping and riveting. This places extremely high demands on the insulation materials and component injection molding. For example, the material must have high durability and hardness, and the deformation of the material must also be considered. It is also necessary to consider the inevitable collapse of the interference position and the related interference position structure due to the size, speed and temperature changes of the force during assembly. This makes it difficult to reduce product costs. This is the first problem. The second problem is that electronic products are developing in the direction of being light, thin, short and multifunctional, and the corresponding connection components must also be reduced in size. In addition, with the increase in functions, the structure of the corresponding connection components, such as the density between components, will also increase. If the electrical conductors adopt clamping and welding processes, it will not only be difficult to ensure product quality, but also increase the difficulty of manufacturing.

2. A process for producing an electrical connection component according to claim 1, characterized in that: Install the two waterproof rings on the bosses of the front and rear seats respectively; Assemble a nut that fits the screw into the hole of the boss; Assembling the two core wires in the groove of the boss and tightening the screws in the groove to squeeze the core wires and fix them to the contact part of the electrical terminal, and The front cover is adapted to the front seat package, and the rear cover is adapted to the rear seat package.

3. A process for producing an electrical connection member according to claim 2, characterized in that: The two waterproof rings are respectively mounted on the bosses of the front and rear seats, wherein: first, one waterproof ring is mounted on the front seat boss of the insulating seat and the base of the waterproof ring is installed in the front seat groove in a filling manner, and then the trapezoidal opening of the waterproof ring installed in the front seat groove corresponds to the notch of the front seat, and then the other waterproof ring is mounted on the rear seat boss of the insulating seat and the base of the waterproof ring is installed in the rear seat groove in a filling manner, and then the trapezoidal opening of the waterproof ring installed in the rear seat groove corresponds to the notch of the rear seat.

4. A process for producing an electrical connection component according to claim 3, characterized in that: The front cover adapted to the front seat is inserted into the front circular groove to form a rotational connection by the front cover shaft, and the rear plate of the front cover is adapted to the axe-shaped block of the front seat through the front cover bayonet to secure the front cover to the front seat; the rear cover adapted to the rear seat is inserted into the rear circular groove to form a rotational connection by the rear cover shaft, and the rear plate of the rear cover is adapted to the axe-shaped block of the rear seat through the rear cover bayonet to secure the rear cover to the rear seat.

5. A process for producing an electrical connection component according to claim 4, characterized in that: A sealing block is assembled in each of the front and rear covers, wherein: When the sealing block is fastened between the front cover and the front seat, the stepped surface inside the front cover squeezes the upper half of the waterproof ring, and at the same time, the trapezoidal tenon of the sealing block in the front cover fits into the trapezoidal opening of the waterproof ring, so that the waterproof ring between the front cover and the front seat and the core wire sandwiched between the trapezoidal tenon and the trapezoidal opening are squeezed at the same time to form a sealed whole; When the sealing block is fastened between the back cover and the back seat, the step surface inside the back cover squeezes the upper half of the waterproof ring. At the same time, the trapezoidal tenon of the sealing block in the back cover adapts to the trapezoidal opening of the waterproof ring, so that the waterproof ring between the back cover and the back seat and the core wire sandwiched between the trapezoidal tenon and the trapezoidal opening are squeezed at the same time to form a sealed whole.
