Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 2 to 6: the embodiment discloses an electric connector protective sleeve, which comprises a protective tube 1, an installation sleeve 3 and a thickening pad 4, wherein the protective tube 1 is provided with a slot 2 parallel to the axis of the protective tube 1, the installation sleeve 3 is connected to the lateral part of the protective tube 1, an installation hole 31 is arranged in the installation sleeve 3, the installation hole 31 is not communicated with the protective tube 1 (figure 5), the thickening pad 4 is arranged at the lateral part of the protective tube 1, the installation sleeve 3 and the thickening pad 4 are connected to the same side of the protective tube 1 (the installation sleeve 3 is used as a boundary, the protective tube 1 is respectively arranged at two sides), the protective tube 1, the installation sleeve 3 and the thickening pad 4 are of an integrated structure, the integrated structure means that the protective tube 1, the mounting sleeve 3 and the thickened pad 4 are not assembled at the later stage, but are integrated in the manufacturing process, because the protective sheath must be insulating material, therefore usually adopt the mode of moulding plastics to make among the prior art, so whole protective sheath is through once only moulding plastics.

This embodiment is still including connecting in the extension 5 of the 1 tip of pillar, and extension 5 sets up in the 4 links of thickening pad of pillar 1, and extension 5 can increase the length of whole protective sheath, makes its isolation distance to two cables longer, and the extension has compensated the drop that the cable produced because of manufacturing tolerance, has increased the intensity that the cable was fixed.

The inner surface of the extension section 5 is an arc surface matched with the inner surface of the protective pipe 1, wherein the matching means that the inner surface of the protective pipe 1 and the inner surface of the extension section 5 are in seamless butt joint, and the inner diameter and the circle center of the inner surface are overlapped.

The extension section 5, the protective pipe 1, the mounting sleeve 3 and the thickening pad 4 are of an integrated structure and are insulated. The integral structure herein is defined as the integral structure described above.

The mounting hole 31 is generally used for clamping a nut of a terminal, and although the nut has a regular hexagon shape, the inner section of the mounting hole 31 should not be designed to be regular hexagon but should be circular because the actual angle of the nut is not fixed.

As shown in fig. 7, this embodiment also discloses an electrical connector, which is provided with the protective sleeve of the electrical connector of this embodiment, and further, the electrical connector has a first electrode 6 and a second electrode 7, so as to avoid this phenomenon, as mentioned in the background art, the terminal of the second electrode 7 and the wire pressing cylinder may contact the cable of the first electrode 6, in order to avoid this phenomenon, the mounting sleeve 3 of the protective sleeve of this embodiment is sleeved on the terminal of the second electrode 7, the cable of the first electrode 6 is put into the protective tube 1 through the slot 2, and at this time, the cable of the first electrode 6 and the wire pressing cylinder are both in the protective tube 1. Meanwhile, the arc groove 41 at the lower end of the thickening pad 4 is clamped on the outer surface of the cable of the second electrode 7, and the thickening pad 4 mainly has two functions, so that the effective isolation thickness of the whole protective sleeve is increased; secondly, the arc groove 41 is used for further realizing the parallelism with the cable of the electrode II 7, and the cable of the electrode I6 and the cable of the electrode II 7 are parallel to the whole protective sleeve as much as possible.

Compared with the prior art, the protective sleeve of the embodiment can isolate the cables between the two electrodes, and relative friction occurs between the two cables (including the wire pressing barrel), so that short circuit occurs. Because the lateral part of pillar 1 is equipped with fluting 2 to installation cover 3 cup joints on the terminal, consequently when the protective sheath damages, also can realize the change to the protective sheath under the prerequisite of not dismantling the cable.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
