Description

Technical Field

[0001] This utility model relates to the field of wire harness connection technology, and in particular to a low-voltage wire harness anti-breakage connection device. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. In industry, they are classified as connectors. With the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control, the use of terminal blocks is gradually increasing. Currently, terminal blocks are commonly used for connections in low-voltage wiring harnesses, automotive wiring harnesses, etc.

[0003] In existing technologies, after low-voltage wiring harnesses are connected, rubber sleeves, reinforcing ribs, or protective springs are usually installed on their outer sides to protect them and reduce damage or breakage in the connection area. However, the above methods have the following drawbacks in actual use: they only achieve a simple anti-breakage effect by increasing structural toughness, and the force buffering and stress dispersion effects are not good. When subjected to repeated traction or violent external forces, the anti-breakage effect is generally poor. Utility Model Content

[0004] Therefore, it is necessary to provide a low-voltage wire harness anti-breakage connection device to address the problems of poor force buffering and stress dispersion effects.

[0005] A low-voltage wire harness anti-breakage connection device includes a connector; it also includes a set of anti-breakage mechanisms; the anti-breakage mechanisms are disposed on the outside of the connector and are used to wrap and limit the low-voltage wire harness to reduce the occurrence of breakage; wherein, the anti-breakage mechanism includes a sheath and two airbag rings, the sheath and the two airbag rings are coaxially arranged with the mating interface on the connector, and the airbag rings are located at the end of the sheath away from the connector.

[0006] In one embodiment, the anti-breakage mechanism further includes a set of balls and a set of grooves, the grooves being formed inside the sheath, and the balls being embedded inside the sheath and positioned between the connector and the grooves.

[0007] In one embodiment, a flared cap is installed at one end of the sheath, the airbag ring is installed to the inner wall of the flared cap, and a set of reinforcing ribs is provided between the two airbag rings.

[0008] In one embodiment, an airbag is fitted on the outer side of the flared cap, and the airbag is in communication with the airbag ring.

[0009] In one embodiment, a restraining strap is provided on the outer side of the flared cap, and an adhesive layer and a barb layer are respectively provided on the outer side of the restraining strap.

[0010] In one embodiment, the sheath is internally embedded with steel wires arranged in a spiral and close to the flared cap.

[0011] In one embodiment, a cover plate is installed inside the flared cap, and the outer side of the cover plate is aligned with the outer side of one of the airbag rings.

[0012] Beneficial effects

[0013] 1. By setting up dual-point airbag rings, the wire harness is wrapped and protected after installation, reducing deformation and breakage. After being subjected to force, it provides segmented and gradual buffering, reducing the occurrence of wire harness breakage caused by strong external force and improving the anti-breakage effect.

[0014] 2. By setting ball bearings and airbag rings, stress is dispersed in multiple areas on the outside of the wire harness to avoid stress concentration. In addition, steel wires are used to improve the structural toughness of the protected area, which facilitates quick reset and effectively copes with repeated traction. Attached Figure Description

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] The following is combined Figures 1-4 This invention describes a low-voltage wire harness anti-breakage connection device.

[0028] In one embodiment, a low-voltage wire harness anti-breakage connection device includes a connector 100 and a set of anti-breakage mechanisms 200. The anti-breakage mechanisms 200 are disposed on the outside of the connector 100 and are used to wrap and limit the low-voltage wire harness to reduce the occurrence of breakage. The anti-breakage mechanism 200 includes a sheath 210 and two airbag rings 220. The sheath 210 and the two airbag rings 220 are coaxially arranged with the mating interface on the connector 100, and the airbag rings 220 are located at the end of the sheath 210 away from the connector 100.

[0029] like Figure 3 As shown, the anti-breakage mechanism 200 also includes a set of balls 230 and a set of grooves 240. The grooves 240 are formed inside the sheath 210, and the balls 230 are embedded inside the sheath 210 and located between the connector 100 and the grooves 240.

[0030] In this embodiment, the low-voltage wire harness is inserted into the connector 100 along the sheath 210. Then, the clamping device on the connector 100 is used to lock and fix the end of the wire harness. Next, the airbag ring 220 is used to wrap and protect two areas on the wire harness. During the insertion of the wire harness, the ball bearing 230 assists in the insertion, ensuring smooth insertion. In subsequent use, when the wire harness tends to bend, the ball bearing 230 will form multi-point protrusions to disperse stress. At the same time, the design of the groove 240 facilitates the deformation of the sheath 210, providing additional space for the bending deformation of the wire harness and reducing the phenomenon of damage caused by the extrusion of the wire harness against the inner wall of the sheath 210. The use of the dual-point airbag ring 220 forms a uniform radial pressure by wrapping the wire harness in a ring, dispersing the external tensile or bending force to the entire circumference of the wire harness, avoiding stress concentration, improving the compressive strength of the wire harness, and the dual-point design allows for segmented protection, effectively resisting violent external forces step by step and improving the anti-breakage effect.

[0031] It should be noted that the two airbag rings 220 are different in size and position, and their wrapping and cushioning effects are also different, achieving the effect of separate protection and gradual cushioning.

[0032] The sheath 210 in this application is made of rubber, which provides protection and can adapt to deformation according to external force. The ball bearing 230 is made of silicone, which can disperse stress by protruding at multiple points, while reducing excessive contact between the wire harness and the ball bearing 230, thus reducing the occurrence of wire harness damage.

[0033] The connector 100 in this application is a terminal block in the prior art. Its internal structure and actual application are existing mature technologies, and will not be described in detail here.

[0034] like Figure 2 and Figure 4As shown, a flared cap 211 is installed at one end of the sheath 210, and an airbag ring 220 is installed on the inner wall of the flared cap 211. A set of reinforcing ribs is provided between the two airbag rings 220.

[0035] The use of a flared cap 211 with reinforcing ribs facilitates the insertion of the wire harness. The reinforcing ribs can limit the airbag ring 220, reduce the expansion of the airbag ring 220 to the side, and ensure that the expansion direction is inward, thereby improving the contact effect with the wire harness.

[0036] like Figure 2 and Figure 4 As shown, an airbag 212 is fitted on the outer side of the flared cap 211, and the airbag 212 is connected to the airbag ring 220.

[0037] When treating the wire harness to prevent breakage, the gas inside the airbag 212 is introduced into the airbag ring 220, so that the airbag ring 220 expands and contacts the outside of the wire harness to perform the protective operation.

[0038] like Figure 2 As shown, a binding strap 213 is provided on the outer side of the flared cap 211, and an adhesive layer and a barb layer are respectively provided on the outer side of the binding strap 213.

[0039] After the wire harness is inserted into place, the restraint strap 213 is used to wrap around the flared cap 211, and then the adhesive layer and barbed layer are used to fix it. At this time, the airbag 212 is compressed and the gas is introduced into the corresponding airbag ring 220.

[0040] like Figure 2 As shown, a steel wire 214 is embedded inside the sheath 210. The steel wire 214 is spirally arranged and close to the flared cap 211.

[0041] The use of steel wire 214 enhances the toughness of the sheath 210, ensuring both flexible protection and return traction force, effectively addressing repeated traction phenomena.

[0042] like Figure 2 As shown, a cover plate is installed inside the flared cap 211, and the outer side of the cover plate is connected to the outer side of one of the airbag rings 220.

[0043] The cover plate is used to abut against the outer airbag ring 220, and the inner wall of the flared cover 211 is used for auxiliary abutment. After the wire harness is inserted, the outer side of the wire harness is wrapped and buffered, while reducing the phenomenon of external dust penetrating into the sheath 210.

[0044] Working principle: The end of the wire harness is inserted into the mating interface of the connector 100 along the sheath 210. Then, the connector 100 is used to press and fix the wire harness. The user then wraps the restraint strap 213 and introduces the gas in the airbag 212 into the airbag ring 220 to wrap and protect the outside of the wire harness. In subsequent use, the ball bearings 230, grooves 240 and airbag ring 220 are used for corresponding protective treatment to reduce stress concentration, excessive wear and buffering.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
