Description

Technical Field

[0001] The present invention relates to the technical field of wiring harnesses, in particular to an automobile wiring harness connector. Background Art

[0002] The connector is an important part of the automotive wiring harness and is used to connect various electrical components on the car. The connector connects the wiring harnesses together by fitting one connector terminal with another connector terminal. Due to the corresponding wiring, the existing connector terminals must be plugged in when connected, which makes the connection more troublesome. If the wiring harnesses on both sides need to be twisted for docking, this will affect the service life of the wiring harness; the metal contacts on the existing connector terminals are generally exposed to the outside, and are easily deformed when encountering bumps, thereby affecting the connection effect of the connector, and in severe cases, causing the connector to fail; at the same time, the existing connectors are generally connected by elastic parts. After multiple disassembly and assembly, the deformation of the elastic parts will cause the connector plug to become loose, affecting the connection quality of the connector.

[0012] Beneficial effects

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] 1. By using a left terminal with a tapered surface and a tapered hole in the right terminal that matches the tapered surface, and concentrically arranging multiple metal cylinders in the right terminal, the left and right terminals can rotate relative to each other when plugged together, eliminating the need for alignment and plugging, saving time and eliminating the need to twist the wire harness, thus extending the life of the wire harness.

[0015] 2. By setting a transmission rod, when the left terminal is inserted into the right terminal, the transmission rod is pushed to drive the flip rod to rotate through the connecting rod, pushing out the multiple metal contacts installed on the flip rod, so that they touch the multiple metal cylinders in the right terminal respectively, completing the circuit connection. When the left terminal is disconnected from the right terminal, the transmission rod drives the flip rod to rotate into the left installation slot, so that the metal contacts on the flip rod are prevented from bumping;

[0016] 3. By providing a protective cover outside the left terminal and a spiral groove inside the protective cover, when the left terminal is inserted into the right terminal, the protrusion on the transmission rod slides in the spiral groove, driving the protective cover to rotate, so that the first notch on the protective cover rotates to the position where the flip rod rotates out, exposing the metal contact; when the left terminal is disconnected from the right terminal and the flip rod is retracted, the first notch on the protective cover rotates away, and the protective cover and the left terminal form a closed space. The metal contact is placed in this closed space to prevent corrosion and oxidation when exposed to water, thereby extending the service life of the wiring harness;

[0017] 4. By arranging a split first card plate and a second card plate at the opening of the right mounting hole of the right terminal, the split first card plate and the second card plate are spliced ​​into a whole when the right terminal is not plugged in, and cover the right mounting position to protect the internal metal cylinder. After the right terminal and the left terminal are plugged in multiple times, the first card plate and the second card plate are moved and positioned, and no gap is generated between the left terminal and the right terminal during plugging due to deformation of the elastic element, which is stable and reliable.

[0027] The limiting assembly includes a first clamping plate 81 and a second clamping plate 82, which are symmetrically hinged to the left end of the right terminal 6.

After the wiring harness passes through the right locking sleeve 22 and is inserted into the right mounting slot 6c, the right locking sleeve 22 is rotated to the left to lock the wiring harness to the right terminal 6.

[0029] like Figure 1 、2 The figure shows the internal structure of the left terminal 1 and the right terminal 6 in the present invention. When the connector needs to be used to connect the two-end wiring harness, one end of the wiring harness needs to be inserted through the left locking sleeve 21 into the left mounting slot 11 of the left terminal 1, the wires in the wiring harness need to be connected to the metal contact 5, and the left locking sleeve 21 is used to fix the wiring harness.

[0030] Then, the first and second torsion springs 91 and 92 are overcome by the first and second shift blocks 8a and 8b to rotate the first clamping plate 81 and the second clamping plate 82, opening the right mounting hole 6a of the right terminal 6, and inserting the left terminal 1 into the right terminal 6 without alignment. When the transmission rod 41 touches the right terminal 6, the left terminal 1 is pushed to the right, so that the transmission rod 41 overcomes the left spring 43 and moves to the left. Since the protrusion 411 slides in the spiral groove 311, the protective cover 31 is driven to rotate, so that the first notch 312 is aligned with the opening of the left mounting notch 11. At the same time, due to the movement of the transmission rod 41, the connecting rod 43 pushes the turning rod 44 to rotate, driving the metal contact 5 to rotate out of the first notch 312.

Under the action of the first torsion spring 91 and the second torsion spring 92, the first clamping plate 81 and the second clamping plate 82 rotate to position the left terminal 1 inside the right terminal 6, completing the plugging of the connector (as shown). Figure 4 、 6 shown).

[0031] When the left terminal 1 and the right terminal 6 need to be separated, the first and second torsion springs 91 and 92 are overcome by the first and second shift blocks 8a and 8b to rotate the first and second clamping plates 81 and 82, so that the left terminal 1 is out of position (such as Figure 5 As shown in the figure, the left terminal 1 is pulled outward, and under the action of the left spring 43, the transmission rod 41 is pushed to the right, and at the same time, the turning rod 44 is driven by the connecting rod 43 to rotate into the left mounting slot 11, so that the metal contact 5 is retracted. Due to the cooperation between the protrusion 411 and the spiral groove 311, the protective cover 31 rotates to close the opening of the left mounting slot 11, thereby protecting the metal contact 5; after the left terminal 1 is pulled out, the first clamping plate 81 and the second clamping plate 82 are released. Under the action of the first torsion spring 91 and the second torsion spring 92, the first clamping plate 81 and the second clamping plate 82 rotate and are spliced ​​together to close the opening of the right terminal 6, thereby protecting the metal cylinder 71 and completing the disconnection of the connector.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
