Technical Field

The invention relates to the technical field of hole type terminals, in particular to a combined hole type terminal joint.

Background

The hole type terminal is a common part on an automobile wire harness product and is mainly used for grounding wires, engine wires, starter wires, battery wires and the like. The existing hole type terminals are all independent wiring terminals, generally cannot be combined for use, and cannot realize multi-path wiring. In addition, the prior hole type terminal capable of being combined has the defects of complex terminal structure, low connection strength, easy disconnection and the like by using the terminal piece combination.

Disclosure of Invention

The invention provides a combined hole type terminal joint aiming at the defects in the prior art, and solves the technical problems that the structure is complex and the hole type terminal joint is easy to be opened and separated when the existing hole type terminal is combined for use.

The technical scheme of the invention is realized as follows: a combined hole type terminal joint comprises a protective shell, wherein the protective shell is connected with a hole type terminal, the hole type terminal is fixed between a bolt and a nut, the protective shell comprises a matching hole corresponding to the bolt, a flange slot is formed in the inner wall of the matching hole, at least two terminal supporting tables are arranged on one side of the matching hole, a hanging spring tongue is arranged on at least one side of each supporting table, the hole type terminal comprises a terminal head portion and a crimping tail portion, a bolt hole and a flange are formed in the terminal head portion, the bolt hole corresponds to the bolt when the flange is inserted into the flange slot, and the terminal head portion is pressed below the hanging spring tongue.

Furthermore, the terminal support table is provided with a limiting bulge, the head of the terminal is provided with a limiting hole, and the limiting hole is in inserting fit with the limiting bulge when the flange is inserted into the flange slot.

Further, a reinforcing rib is arranged between the terminal head part and the crimping tail part.

Furthermore, hanging elastic tongues are arranged on two sides of the supporting platform, and the two hanging elastic tongues are pressed on two sides of the reinforcing rib on the hole type terminal.

Furthermore, the protective shell is provided with three supporting tables, and the three terminal supporting tables are arranged at intervals along the circumferential direction of the matching hole.

Further, the three support tables have different horizontal heights, and the three terminal heads provided on the three terminal support tables are superposed on each other.

Further, the bolt holes or/and the matching holes are regular polygonal holes, and regular polygonal columns matched with the regular polygonal holes are arranged on the bolts.

Furthermore, a hook is arranged on the lower end face of the matching hole, and the lower end head of the bolt is clamped between the hook and the terminal head.

And a step for supporting the head of the terminal is arranged between the upper part of the matching hole and the lower part of the flange slot.

The invention has simple structure, and can connect a plurality of hole-type terminals in the same protective shell, and each hole-type terminal is convenient to be installed and detached with the protective shell and can reliably limit each hole-type terminal. The method has the following specific beneficial effects:

1. the flange of the terminal is obliquely inserted into the protective shell flange slot, the terminal crimping tail part is pressed downwards, the limiting bulge extends into the limiting hole, and meanwhile, the hole type terminal is hung with the hanging spring tongue, so that the hole type terminal and the protective shell realize axial and circumferential positioning, and the combination of the terminal and the protective shell is completed.

2. The flange is matched with the flange slot and the limiting bulge and the limiting hole, so that the terminal is prevented from swinging in the horizontal direction, and the consistency of hole positions of a plurality of terminal bolt holes is ensured.

3. The hole type terminal is prevented from swinging up and down by hooking the terminal with the hooking elastic tongue.

4. The bolt is connected to the vehicle body, and the regular polygonal hole of the terminal or the sheath is matched with the regular polygonal column of the bolt to prevent the relative rotation of the vehicle body.
