Description

Technical Field

[0001] The utility model specifically relates to the technical field of wire harness sealing, in particular to a wire harness self-sealing structure. Background Art

[0002] The self-sealing structure of the wiring harness is widely used in automobiles, electronic equipment and other fields. It can effectively prevent dust, moisture and other impurities from entering the interior of the wiring harness, thereby protecting the wires and electronic components in the wiring harness, ensuring the normal operation of the equipment, and effectively ensuring the service life of the wiring harness.

[0003] However, when traditional wiring harnesses are connected, the copper wire or aluminum wire in the wiring harness is cut to expose it to the outside, so that the copper wire and the aluminum wire are directly connected. This can easily cause the wiring harness to become loose between the wiring harness and the connected device, resulting in the wiring harness being unable to make effective contact, thereby causing the transmitted signal to be lost. Once the wiring harness and the connected device become loose, external dust or moisture in the air may contaminate the wiring harness, and the working efficiency and quality of the wiring harness cannot be effectively guaranteed.

[0004] After searching, Chinese patent publication number CN202023018324.8 discloses a wire harness sealing structure; comprising a wire harness and an insulating sheath, wherein the wire harness is wrapped in the insulating sheath, a notch is provided in the middle of the insulating sheath, the wire harness is composed of a plurality of stranded wire guides, a sealing structure is provided between the plurality of stranded wire guides located at the notch, and a sleeve is provided at the notch;

[0005] The sealing structure in the above patent is designed to seal the wire harness through the contact between the tin layer and the sealant. This can avoid the loss of the stranded wire guide and effectively ensure the transmission effect of the stranded wire guide. It is then effectively wrapped and sealed by the sealant and the sleeve. In this way, when the gap appears in the middle of the wire harness, the two ends of the wire harness are connected to the equipment, and the placement and installation of the sleeve cannot be achieved. Moreover, when the sleeve in the above patent is installed and used, it is impossible to effectively ensure that the inner wall of the sleeve is tightly fitted with the outer surface of the wire harness. Utility Model Content

[0006] The purpose of the utility model is to provide a self-sealing structure for a wiring harness, in which a circular ring is sleeved on the end of the rubber sleeve, and the external thread on the clamping plate wall of the circular ring is effectively contacted with the internal thread in the matching groove of the cover body, so that the anti-interference layer at the end of the rubber sleeve and the multi-strand wiring harness are passed into the concave cavity of the cover body, and then the wiring harness is transmitted through the threading hole on the cover body, thereby effectively ensuring the connection of the wiring harness. When sealing, the anti-interference layer and the wiring harness are squeezed inward through the cooperation of the cover body and the clamping plate, and the positioning column inside the cover body effectively blocks the anti-interference layer and the wiring harness, thereby effectively ensuring close contact between the cover body and the rubber sleeve, and preventing external dust, oil and water from entering the interior of the rubber sleeve, so as to solve the problems of the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A self-sealing structure for a wiring harness comprises a wiring harness; the wiring harness is provided with pairs of wiring harnesses, each of which is wrapped with an anti-interference layer; the anti-interference layer is externally fitted with a rubber sleeve, the end of the rubber sleeve is provided with a circular ring, one side of the circular ring is integrally provided with a plurality of clamping plates, the cross-section of the clamping plates being a right-angled triangle; the inclined surfaces of the clamping plates are integrally provided with external threads;

[0009] As a further technical solution of the present invention, the external thread is connected to the cover body in a mating manner; a mating groove is provided on the side wall of the cover body; the width of the mating groove is the same as the thickness of the rubber sleeve; thus, the cross section of the end of the rubber strip is effectively sealed by the mating groove, preventing external dust and water from entering the rubber sleeve and causing damage to the wiring harness;

[0010] As a further technical solution of the present invention, the side of the matching groove is integrally provided with an internal thread; the internal thread is detachably connected to the external thread;

[0011] As a further technical solution of the present invention, a raised positioning column is provided on the top surface of the inner cavity of the cover; the positioning column is located in the middle of the plurality of wiring harnesses; the positioning column blocks the anti-interference layer and the wiring harness, effectively ensuring that the clamping plate effectively clamps and seals the anti-interference layer and the wiring harness;

[0012] As a further technical solution of the present invention, the cover is further provided with threading holes having the same number as the wire harness; the threading holes are located at the edge of the positioning column and are arranged in an array;

[0013] As a further technical solution of the present invention, the positioning post is located in the middle of the end of the rubber sleeve and is in contact with multiple anti-interference layers;

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When using the utility model, the end of the rubber sleeve is firstly set in a circular ring, and then the multiple wire harnesses are passed through the wire holes on the cover body to avoid squeezing the wire harnesses, ensuring that data loss does not occur during transmission of the wire harnesses, and ensuring the stability and safety of the wire harness transmission;

[0016] The utility model rotates the external thread on the side wall of the clamping plate on the circular ring and the internal thread in the matching groove to achieve the effect of detachable connection. Through the rotation, the multiple clamping plates on the circular ring can simultaneously squeeze the anti-interference layer and the wiring harness inward to achieve a contraction effect. At the same time, as the cover moves, the positioning column gradually moves to the middle position of the multiple wiring harnesses to achieve blocking of the anti-interference layer and the wiring harness, thus effectively ensuring the sealing effect of the rubber sleeve, the anti-interference layer and the wiring harness.

[0017] The utility model, when the cover body is rotated, the cross section of the end portion of the rubber sleeve enters the interior of the matching groove, and the sealing effect of the cross section of the end portion of the rubber sleeve is achieved through the inner and outer side walls of the matching groove, thereby effectively ensuring the effective sealing effect of the end portion of the rubber sleeve and preventing dust, water and oil from penetrating into the interior of the rubber sleeve.

[0026] The external thread 22 is connected to the cover body 30 in a mating manner. A mating groove 31 is formed on the side wall of the cover body 30 . The width of the mating groove 31 is the same as the thickness of the rubber sleeve 10 .

[0027] By adopting the above technical solution, when in use, the end of the rubber sleeve 10 is firstly sleeved with the ring 21, and then the multiple strands of wire harness 12 are passed through the threading hole 34 on the cover body 30, thereby avoiding squeezing of the wire harness 12, ensuring that data loss does not occur during transmission of the wire harness 12, and ensuring the stability and security of the transmission of the wire harness 12;

[0028] An internal thread 32 is integrally provided on the side of the matching groove 31 ; the internal thread 32 is detachably connected to the external thread 22 .

[0029] In this embodiment, a raised positioning post 33 is provided on the top surface of the inner cavity of the cover 30; the positioning post 33 is located in the middle of the plurality of wiring harnesses 12;

[0030] By adopting the above technical solution, the external thread 22 on the side wall of the clamping plate 22 on the ring 21 is rotated with the internal thread 32 in the matching groove 31 to achieve the effect of detachable connection. Through the rotation, the multiple clamping plates 22 on the ring 21 are simultaneously squeezed inward on the anti-interference layer 11 and the wiring harness 12 to achieve a contraction effect. At the same time, as the cover body 30 moves, the positioning column 33 gradually moves to the middle position of the multiple wiring harnesses 12 to achieve blocking of the anti-interference layer 11 and the wiring harness 12, thereby effectively ensuring the sealing effect of the rubber sleeve 10, the anti-interference layer 11 and the wiring harness 12.

[0031] In this embodiment, the cover 30 is further provided with threading holes 34 having the same number as the wire harness 12; the threading holes 34 are located at the edge of the positioning column 33 and are arranged in an array;

Through the rotation, the multiple clamping plates 22 on the ring 21 can simultaneously squeeze the anti-interference layer 11 and the wiring harness 12 inward to achieve a contraction effect. At the same time, as the cover body 30 moves, the positioning column 33 gradually moves to the middle position of the multiple wiring harnesses 12 to block the anti-interference layer 11 and the wiring harness 12, thereby effectively ensuring the sealing effect of the rubber sleeve 10, the anti-interference layer 11 and the wiring harness 12.

[0036] When the cover body 30 is rotated, the end section of the rubber sleeve 10 enters the interior of the matching groove 31, and the sealing effect of the end section of the rubber sleeve 10 is achieved through the inner and outer side walls of the matching groove 31, thereby effectively ensuring the effective sealing effect of the end of the rubber sleeve 10 and preventing dust, water and oil from penetrating into the interior of the rubber sleeve 10.
