[0026] Embodiment

[0027] The embodiment provides a terminal sheath of an automobile connector, the automobile connector comprising a female plug terminal 1, the female plug terminal 1 comprising a connecting terminal 11 and a wire 12 arranged on the connecting terminal 11, the terminal sheath 2 comprising a wrapping end 21 wrapped outside the female plug terminal 1 and a bent end 22 connected to a side of the wrapping end 21 and used for wrapping the wire 12, the bent end 22 being hollow inside, a through hole 3 being arranged at the bent end 22 and used for the wire 12 to pass through, and a deformation part 23 being arranged on an outer end surface of the bent end 22.

[0028] The specific improvement is that, as shown in Figure 1 and Figure 2 , during installation, the wire on the female plug terminal is first passed through the wrapping end and the bent end and then passes out of the through hole, so that the female plug terminal is located at the wrapping end, the wire passes out of the through hole through the bent end, and then a male plug terminal matched with the female plug terminal is inserted into the female plug terminal, so that the terminal sheath is wrapped outside the connecting terminal and the wire, the wire can be effectively prevented from being abraded during use, dust outside can be effectively prevented from entering the wire and the connecting terminal and causing internal circuit short circuit, and the deformation part is arranged on the outer part of the terminal sheath, so that the wire can be bent, wherein the plug-in structure of the male plug terminal and the female plug terminal is prior art, and the plug-in structure between the two is not described herein.

[0029] On the basis of the above embodiment, a buckling structure 4 for fixing connection is arranged between the connecting terminal 11 and the wrapping end 21.

[0030] The specific improvement is that, as shown in Figure 2 , in order to increase the connection tightness of the connecting terminal and the terminal sheath and prevent the connecting terminal from being separated from the terminal sheath, the buckling structure is arranged between the two, and when the connecting terminal is inserted into the terminal sheath, the buckling structure buckles the two together to prevent the two from being separated.

[0031] On the basis of the above embodiment, the deformation part 23 is in a corrugated structure.

[0032] The specific improvement is that the deformation part in a corrugated structure is arranged on the outer part of the terminal sheath, so that the deformation part can be bent and deformed during use, the wire can be better guided to be bent, and the wire can adapt to more installation scenes.

[0033] On the basis of the above embodiment, the buckling structure 4 comprises a buckling block 41 arranged on one of the outer side surface of the connecting terminal 11 or the inner side surface of the wrapping end 21 and a buckling groove 42 matched with the buckling block 41.

[0034] The specific improvement is that, as shown in Figure 2As shown, the buckling structure includes a buckling block provided on the connecting terminal and a buckling groove provided on the inner side wall of the wrapping end. The buckling block is provided on an extension rod which can be deformed. A barb is provided on the buckling block. When the connecting terminal is inserted into the wrapping end, the extension rod is deformed from the outside to the inside to accumulate elastic potential energy. When the buckling block on the extension rod reaches the position of the buckling groove, the extension rod releases the elastic potential energy so that the buckling block is clamped in the buckling groove.

[0035] On the basis of the above embodiment, the female terminal 1 is provided with an extension sleeve 5, and the wrapping end 21 is provided with a resisting groove 51 which is adapted to the extension sleeve 5.

[0036] The specific improvement is that, as shown in Figure 2 and Figure 4 As shown, the female terminal has an extension sleeve. In order to increase the contact area between the female terminal and the terminal sheath, a resisting groove which can resist the extension sleeve is provided on the wrapping end. When the female terminal is inserted into the terminal sheath and the extension sleeve resists the resisting groove, the female terminal cannot be pushed forward any more, thereby effectively improving the fit between the female terminal and the terminal sheath.

[0037] On the basis of the above embodiment, the female terminal 1 is provided with an extension part 6 for inserting the wire 12. The extension part 6 is provided with a connecting groove 61 for inserting the wire 12. One end of the wire 12 is inserted into the connecting groove 61, and the other end extends to the outside of the through hole 3. The through hole 3 is provided with a plurality of annular sealing rings 62 which are arranged in an array.

[0038] The specific improvement is that, as shown in Figure 3 and Figure 5 As shown, the female terminal has an extension part which is connected with the wire. In the installation process, the wire is first inserted into the connecting groove of the extension part, and then the connected wire and the female terminal are put into the terminal sheath. In order to prevent the external dust, moisture and other impurities from entering the female terminal from the through hole, an annular sealing ring is arranged in the through hole. The annular sealing ring can tightly fit the outer side surface of the wire, thereby avoiding the entry of external impurities from the connecting gap between the wire and the through hole.

[0039] On the basis of the above embodiment, the wrapping end 21 is further provided with a containing groove 7 for containing the extension part 6. A heat dissipation cavity 8 is arranged between the extension part 6 and the containing groove 7. The heat dissipation cavity 8 is in communication with the inside of the bending end 22.

[0040] The specific improvement is that, as shown in Figure 2As shown, the male and female plug terminals generate a large amount of heat when current passes through, so the heat generated by the male and female plug terminals is conducted to the heat dissipation cavity between the extension 6 and the accommodating groove 7, and then conducted to the outside through the heat dissipation cavity. The rubber can be heat-conducting silicone rubber, or heat-conducting fillers such as boron nitride, kaolin, potassium feldspar, etc. can be added to the rubber to improve the heat conductivity of the rubber.

[0041] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
