Description

Technical Field

[0001] This utility model relates to the field of signal transmission harness technology, and in particular to a combined signal transmission harness. Background Technology

[0002] For wire harnesses requiring plug connections for signal transmission, the core challenge lies in reliably securing the conductors inside the harness to the plug's contact points and maintaining stable electrical continuity over a long period. A common practice is to directly insert the conductor ends into the metal contact sleeve (or pin base) inside the plug, sometimes supplemented by simple spot welding, crimping, or adhesive bonding. While this method achieves a basic connection, it presents significant risks when faced with unavoidable lateral pulling, bending stress, or continuous vibrations from equipment operation during actual use. The conductor's fixation relies solely on adhesive or mechanical interlocking at or near the contact point, lacking effective buffering and stress dispersion mechanisms. When the wire harness is subjected to external forces, especially repeated or continuous pulling or shaking, the force is directly transmitted to the vulnerable connection point, easily causing the conductor to undergo slight displacement or even gradual detachment within the contact sleeve, ultimately resulting in intermittent signal transmission or complete interruption (i.e., "disconnection").

[0003] To overcome the aforementioned issue of loosening at connection points, some improvements have strengthened the conductor's confinement within the plug structure. For example, a fixed wire clamp or clip structure can be installed at the rear of the plug housing, or a specialized rubber ring can be used for tightening. The core idea is to apply additional radial clamping force to the outer insulation layer surrounding the conductor at the "neck" position after the conductor enters the plug housing, using rigid or elastic clamping components. This approach aims to increase the friction between the conductor insulation layer and the plug housing, attempting to indirectly prevent the internal conductor from sliding by restricting the axial movement of the insulation layer. This improves resistance to direct pulling to some extent, avoiding the risk of the conductor being instantly pulled out of the contact sleeve, and making the connection more stable when subjected to direct tensile force in a single direction.

[0004] While the aforementioned clamping or tightening structures improve resistance to linear pulling, they fail to effectively address two key issues. First, in actual working environments, high-frequency, multi-directional minute vibrations or impacts from the equipment or the wiring harness itself (such as equipment vibration, cable swaying, or accidental collisions) continuously act on the wiring harness. Rigid or simply elastic fixing structures have limited effectiveness in dispersing and absorbing such dynamic stresses, and vibrational energy will still be transmitted to the conductor-contact cylinder connection point to varying degrees. Over time, this continuous, localized stress will exacerbate fatigue of the metal material at the connection point or cause the fixing ring to age and loosen, resulting in internal contact misalignment or incomplete connection (i.e., the conductor end experiences a slight displacement within the contact cylinder that is sufficient to affect conductivity), even if it is not fully pulled out. Ultimately, this may still lead to unstable signal transmission or disconnection. Second, this method of tightening at the plug "neck" is usually unidirectional and non-adjustable (for example, after clamping, the wiring harness can only extend in a fixed direction). This means that during actual installation, if the orientation of the device socket does not match the ideal routing path of the wiring harness (e.g., the socket faces downwards while the wiring harness needs to be led out horizontally, or vice versa), users have to forcibly bend the part of the wiring harness near the plug outlet to adapt to the orientation. This rigid bending at a fixed angle causes the wiring harness to be subjected to enormous torsional or shear forces at the base of the plug, making the conductor and its insulation layer highly susceptible to fatigue fracture due to repeated bending stress. Furthermore, this structure prevents users from flexibly choosing the optimal direction for the wiring harness to exit the plug (vertically downwards or horizontally parallel) according to on-site installation requirements, limiting installation flexibility and adaptability to different equipment layouts. Therefore, there is an urgent need for a comprehensive solution that can both firmly resist direct pulling and dynamic vibration impacts and provide flexible wiring exit directions to avoid damage from bending at the base. Utility Model Content

[0005] The purpose of this utility model is to provide a combined signal transmission harness to solve the problems of slight displacement (lack of connection) of the conductor and the internal connection point of the plug contact cylinder caused by the inability to effectively disperse high-frequency multi-directional vibration in the actual use of the plug that uses wire clamps or clamping structures to fix the harness, as well as the problem of conductor fatigue fracture caused by the fixed non-adjustable wire direction forcing the harness to be rigidly bent at the root of the plug.

[0006] To achieve the above objectives, this utility model provides a combined signal transmission harness, comprising two first clamping plates and two second clamping plates. The first clamping plates are respectively fixedly installed on both sides of the top of a middle clamping plate. Trapezoidal grooves are respectively opened on both sides of the middle clamping plate. The second clamping plates are respectively fixedly installed on the top of the trapezoidal plates. The trapezoidal plates are respectively fixedly installed on both sides of the top of a lower clamping plate. A through groove is opened in the middle of the lower clamping plate. The first clamping plates are respectively attached to the second clamping plates, with the first clamping plates located outside the second clamping plates. After attachment, the trapezoidal plates are respectively embedded in the trapezoidal grooves. A slot is opened on the top of the first clamping plates. A first clamping block is fixedly installed on the outer side of the top of the second clamping plates.

[0007] The first card plate and the second card plate are attached together and simultaneously inserted into the slot. A baffle is fixedly installed below the opening of the slot. A second card block is fixedly installed on the upper side wall of the slot opposite to the opening.

[0008] The first card plate and the second card plate are simultaneously inserted into the slots, the slots are connected to the second card blocks, and the first card blocks are engaged with the top of the baffle.

[0009] The slots are respectively opened on both sides of the plug, and the top of the plug has several through holes that extend to the bottom of the plug, and each through hole has a plug contact cylinder fixedly installed inside it.

[0010] The bottom end of the insertion contact cylinder is fixed with one end of the transmission conductor, and the outer side of the transmission conductor is covered with a conductor insulating sleeve. The outer radial side of the conductor insulating sleeve is clamped between the middle clamp plate and the plug.

[0011] The conductor insulating sleeve passes parallel to the middle clamp and the plug, and is then clamped again between the middle clamp and the lower clamp, and passes downward from the through groove or parallel from the middle clamp and the lower clamp.

[0012] The conductor insulating sleeves are simultaneously covered with a filling layer, the filling layer is covered with a shielding layer, the shielding layer is covered with an outer sheath, and the outer sheath is respectively engaged in the receiving groove.

[0013] The storage slots are respectively opened at both ends of the rubber block, and a binding strap is fixedly installed at the bottom of the rubber block. A Velcro hook is fixedly installed on one side of the binding strap.

[0014] In this embodiment, a Velcro strap is fixedly installed on the binding strap adjacent to the Velcro hook, and the Velcro hook and Velcro strap are bonded together to form a binding strap covering a rubber block.

[0015] This utility model discloses a combined signal transmission harness. Two first clamping plates are fixedly installed on both sides of the top of a middle clamping plate, forming a basic support structure. Two second clamping plates are fixedly installed on the top of a trapezoidal plate, which is firmly set on both sides of the top of a lower clamping plate. The middle clamping plate has trapezoidal grooves with specific contours on both sides, while the lower clamping plate has a through groove in the middle. During assembly, the first and second clamping plates are surface-fitted, with the first clamping plate located outside the second clamping plate. During this process, the trapezoidal plate fixed to the trapezoidal plate simultaneously embeds into the trapezoidal groove of the middle clamping plate, forming a beveled fit with a self-locking tendency. This wedge-shaped interlocking structure of the trapezoidal plate and trapezoidal groove enhances the tensile and shear resistance between the middle and lower clamping plates, helping to disperse externally applied tensile forces or vibration energy generated during equipment operation, reducing the adverse effects of these external forces on the stability of internal electrical connection points.

[0016] The transmission conductor is encased in a conductor insulation sleeve, which is constrained within the limited space between the middle clamp and the plug, forming the first constraint on the axial movement of the conductor. After the conductor insulation sleeve is led out from the clamping area between the middle clamp and the plug, it can be guided back into another clamping area formed between the middle clamp and the lower clamp, depending on the actual wiring requirements. At this point, the user has two path options: the conductor insulation sleeve can be led out vertically downward through the through slot in the middle of the lower clamp, or extended horizontally along the parallel gap between the middle clamp and the lower clamp. This design, with both through slots and parallel gaps, allows the harness body to flexibly choose between vertical or horizontal exit directions based on the actual orientation of the equipment interface and the available space. This directional adjustability helps avoid excessive bending stress at the root of the harness, especially near the plug connection, caused by forcibly bending the harness to adapt to a fixed direction, thereby reducing the risk of fatigue damage to the conductor due to repeated or improper bending.

[0017] The overlapping and bonding of the first and second clamping plates provides basic connection strength, the embedded fit of the trapezoidal plate and trapezoidal groove enhances resistance to dynamic loads, and the coexistence of through slots and parallel clamping openings provides directional freedom. This structure works synergistically to improve the reliability of signal transmission. On one hand, the interlocking design of rigid components enhances the connection points' resistance to external pulling forces and vibration interference, helping to maintain the stability of the electrical connection of the conductor within the contact cylinder. On the other hand, the selectable cable exit path effectively reduces the risk of forced bending due to mismatched installation directions, providing structural support for the long-term reliable operation of the wiring harness in complex environments.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see Figures 1-4 .

[0026] This utility model provides a combined signal transmission harness, comprising two first clamping plates 101 fixedly installed on both sides of the top of a middle clamping plate 103. Trapezoidal grooves 104 are respectively formed on both sides of the middle clamping plate 103, which are used to accommodate subsequent trapezoidal plates 105 to form a wedge-shaped positioning, thereby restricting the horizontal movement of related components. The trapezoidal plates 105 are respectively fixedly installed on both sides of the top of a lower clamping plate 106, and two second clamping plates 102 are respectively fixedly installed on the top of the trapezoidal plates 105. The first clamping plates 101 are respectively attached to the second clamping plates 102, and the first clamping plates 101 are located outside the second clamping plates 102. This relative positional relationship provides lateral constraint. When the first clamping plates 101 and the second clamping plates 102 are in place, the trapezoidal plates 105 at the bottom of the trapezoidal plates 105 fixedly installed on the top of the lower clamping plate 106 will respectively embed into the trapezoidal grooves 104 on the side of the middle clamping plate 103, forming a mechanical interlock, further enhancing the stability and alignment accuracy of the structure. A through groove 107 is provided in the middle of the lower clamping plate 106. The through groove 107 is used to provide a downward vertical path for the conductor insulation sleeve 118 and the internal transmission conductor 117 to adapt to different installation direction requirements.

[0027] Two mating first locking plates 101 and second locking plates 102 are simultaneously inserted into slots 111 on both sides of the plug 114, connecting the wire harness to the plug 114. A baffle 112 is fixedly installed below the opening of the slot 111, restricting the upward displacement of the first locking block 110 above the second locking plate 102 to prevent it from dislodging. A second locking block 113 is fixedly installed on the upper side wall opposite the opening of the slot 111, engaging with the slot 109 above the first locking plate 101 to form a snap-fit ​​connection, further enhancing the connection's strength. When the first card plate 101 and the second card plate 102 are simultaneously inserted into the slot 111, the card groove 109 above the first card plate 101 forms an engaging connection with the second card block 113 above the inner wall of the slot 111. At the same time, the first card block 110 fixedly installed on the outer side of the top of the second card plate 102 engages with the top of the baffle 112. This engaging relationship between the first card block 110 and the top of the baffle 112, combined with the cooperation of the card groove 109 and the second card block 113, constitutes a stable three-point locking structure.

[0028] The plug 114 has several through holes 115 at its top end, extending vertically from the top to the bottom, providing a physical channel for signal transmission. Each through hole 115 houses a contact cylinder 116, a key electrical contact component that directly interfaces with external devices. One end of a transmission conductor 117 is fixedly fixed inside the bottom of the contact cylinder 116; the transmission conductor 117 carries and transmits electrical signals. Conductor insulating sleeves 118 cover the outside of the transmission conductor 117, providing electrical insulation and mechanical strength. In the crucial fixing structure, the radially outer portion of the conductor insulating sleeve 118 is firmly clamped between the middle clamp 103 and the plug 114, forming the first fixing constraint to prevent the transmission conductor 117 from being axially pulled and causing it to loosen from the contact cylinder 116.

[0029] After the conductor insulation sleeve 118 and its internal transmission conductor 117 pass parallel through the clamping area between the middle clamp 103 and the plug 114, they are clamped again in the parallel space between the middle clamp 103 and the lower clamp 106, providing a continuous and uniform gripping force to prevent displacement and forming a second fixing constraint to prevent the transmission conductor 117 from being pulled out. After the conductor insulation sleeve 118 and the transmission conductor 117 come out of this parallel clamping area, they have two paths to choose from: one is to pass directly downwards and vertically through the through slot 107 opened in the middle of the lower clamp 106, forming a vertically downward wiring direction; the other is to extend along the parallel opening between the middle clamp 103 and the lower clamp 106, forming a horizontal wiring direction. This dual-path design allows installers to flexibly choose the lead-out direction of the main body of the wire harness according to the actual orientation of the equipment socket interface and the limitations of the wiring space, avoiding excessive bending stress on the transmission conductor 117 due to its non-natural bending state during subsequent use of the plug 114, and reducing the risk of fatigue fracture of the transmission conductor 117.

[0030] The multiple conductor insulation sleeves 118 are not independently dispersed, but are tightly and uniformly filled in the gaps between them by a filler layer 119. The filler layer 119 is generally made of a flexible non-conductive material, and its main function is to fill the gaps to make the cross-section of the wire harness more rounded, disperse external pressure, and enhance the overall compressive and bending resistance of the wire harness. A shielding layer 120 is completely covered on the outside of the filler layer 119. The shielding layer 120 is usually made of metal braided mesh or conductive film material. Its core function is to form a continuous conductive shield, effectively blocking external electromagnetic interference (EMI) from affecting the signal of the internal transmission conductor 117, while preventing internal signal radiation from interfering with external equipment, ensuring the integrity and quality of signal transmission. The outermost part of the shielding layer 120 is completely covered by a tough outer sheath 121. The outer sheath 121, as the outermost protective barrier of the wire harness, is made of wear-resistant and environmentally resistant polymer material. Its main function is to provide physical protection for all internal components, resist the corrosion of external factors such as friction, impact, oil, and moisture, and provide additional electrical insulation protection.

[0031] To organize and secure the main body of the wire harness and prevent it from becoming tangled and dragging, the outer sheath 121 of the wire harness is engaged within a specially designed storage slot 122. The storage slots 122 are located at both ends of a rubber block 123. The rubber block 123 is elastic, providing a flexible and secure engagement to reduce pressure damage to the surface of the outer sheath 121. A binding strap 124 is fixedly installed at the bottom of the rubber block 123 for wrapping around and tightening it. A hook and loop fastener 125 is fixedly installed on one side of the binding strap 124, and a Velcro fastener 126 is fixedly installed on the binding strap 124 adjacent to the hook and loop fastener 125. When it is necessary to fix the outer sheath 121 of the wire harness stored in the storage groove 122 of the rubber block 123, the operator only needs to wrap the binding strap 124 around the rubber block 123 once, and then tightly adhere the hook and loop fastener 125 and the Velcro fastener 126 to form a covering structure in which the binding strap 124 covers the rubber block 123. This structure can effectively tighten the binding strap 124, thereby generating inward tightening pressure, locking the opening edge of the storage groove 122, ensuring that the outer sheath 121 segment inserted therein is firmly held in the storage groove 122, preventing it from falling out, and achieving neat and reliable fixing of the wire harness.

[0032] Working principle: When the signal transmission harness needs to be connected to equipment, the end of the transmission conductor 117 is pre-securely fixed inside the contact sleeve 116, forming the core path for communication. At this time, the plug 114 can support the contact sleeve 116 and be inserted into the corresponding interface of the target device, achieving precise electrical signal transmission and connection through these contact sleeves 116. To ensure that the connection of the transmission conductor 117 inside the contact sleeve 116 is stable and reliable, and to prevent the conductor from loosening or even falling out of the contact sleeve 116 due to pulling or vibration during daily use, the operator will cleverly use the conductor insulation sleeve 118 (usually made of high insulation strength materials such as PVC, XLPE or special plastics, whose main function is to provide electrical insulation and basic physical protection for the internal transmission conductor 117) wrapped around the transmission conductor 117 as a support and fixing carrier. The conductor insulation sleeve 118, including the transmission conductor 117, is moderately bent and then guided into the narrow space between the middle clamp 103 and the plug 114. This space generates an effective radial clamping force on the conductor insulation sleeve 118, forming the first constraint to prevent axial displacement of the conductor.

[0033] Next, the conductor insulation sleeve 118, after emerging from the clamping area between the middle clamp 103 and the plug 114, can be bent again as needed, guiding it into another parallel clamping area formed by the bottom of the middle clamp 103 and the top of the lower clamp 106. This area also provides a stable clamping effect for the conductor insulation sleeve 118, offering continuous holding force. Notably, the conductor insulation sleeve 118 (along with its internal transmission conductor 117) can choose between two paths: one is to pass directly downwards vertically through the through slot 107 in the middle of the lower clamp 106, forming a vertically downward exit direction; the other is to extend along the parallel opening between the middle clamp 103 and the lower clamp 106, forming a horizontal or near-horizontal exit direction. This selectable exit path design directly gives the user the ability to flexibly adjust the orientation of the plug 114 relative to the entire wire harness body during actual installation. Users can choose the most suitable cable exit direction (vertical or horizontal) based on the actual location and orientation of the device socket and the optimal path for cable routing. This significantly avoids the risk of fatigue damage or even breakage of the transmission conductor 117 due to excessive or unreasonable bending angles at the tail of the plug 114 after insertion. Furthermore, the double clamping of the conductor insulation sleeve 118 and the internal transmission conductor 117 at the aforementioned critical locations (between the middle clamp 103 and the plug 114, and between the middle clamp 103 and the lower clamp 106), combined with the conductor's fixation within the contact cylinder 116, constitutes a multi-layered anti-dislodgement protection mechanism, greatly enhancing the overall connection reliability.

[0034] It is worth emphasizing that the multiple transmission conductors 117 and their respective conductor insulation sleeves 118 are not isolated. They are tightly and uniformly filled with a soft, non-conductive filler layer 119 (commonly made of polypropylene rope, hemp thread, or non-hygroscopic filler paste, etc., whose main function is to fill the gaps between the conductors, maintain the roundness of the wire harness cross-section, disperse external pressure, and enhance the overall mechanical strength and bending resistance of the wire harness). Beyond this filler layer, a dense shielding layer 120 is uniformly wrapped (usually made of materials such as metal braided mesh, aluminum-plastic composite tape, or conductive polymers, whose core function is to form a continuous conductive path, effectively isolating the internal signal conductors from external electromagnetic fields, shielding the signal from external electromagnetic interference, and preventing internal signal radiation from interfering with external equipment, ensuring high-quality and stable signal transmission). Finally, the outermost layer of the entire wire harness is a tough and wear-resistant outer sheath 121 (commonly made of materials such as PVC, polyurethane, TPE, or special rubber, etc., serving as the outermost barrier of the wire harness, mainly responsible for resisting environmental erosion, mechanical wear, chemical corrosion, ultraviolet radiation, and providing additional electrical insulation protection).

[0035] Finally, for the storage and organization of the entire wire harness body (i.e., the part covered by the outer sheath 121) that encloses the shielding layer 120, the filling layer 119, the conductor insulation sleeve 118, and the transmission conductor 117, a specific position can be selected during operation, and the outer sheath 121 section that needs to be fixed can be flexibly inserted into the dedicated storage slots 122 at both ends of the rubber block 123. The properties of the rubber material provide a flexible and inclusive locking effect, reducing the pressure on the surface of the wire harness. In order to keep the stored outer sheath 121 section firmly in the storage slots 122 and prevent it from easily coming out, the operator needs to use the attached binding strap 124 to wrap around the rubber block 123, and then use the Velcro hooks 125 and Velcro tapes 126 fixed on both sides of the binding strap 124 to stick them together. This adhesive closure action allows the binding strap 124 to tightly wrap around the entire rubber block 123. Its tightening force effectively secures the entrance edge of the storage groove 122, effectively forming a flexible yet robust closed boundary. This reliably restrains the outer sheath 121 portion inserted within, achieving a neat, stable, and wear-resistant storage and fixation state. The entire process fully demonstrates the comprehensive technical effects achieved by the collaborative work of each component: convenient installation, reliable connection, adjustable direction, protection against bending and breakage, anti-interference protection, mechanical environmental protection, and neat storage.
