Description

Technical Field

[0001] This application belongs to the field of cable technology, specifically relating to an eccentric, angled military cable assembly. Background Technology

[0002] As a key connecting component in military equipment systems, the reliability and stability of military cables directly affect the overall performance and combat effectiveness of the equipment.

[0003] Currently, the locking methods for angled cable assemblies commonly employ spring-loaded locking and screw locking. For example, Figure 1 A. The locking reliability of the spring clip locking method is low, and it cannot connect the female and male connectors and the panel in the angled cable assembly into one unit, making it difficult to meet the requirements of stable connection.

[0004] While screw locking is generally recognized as a highly reliable locking method, however, as... Figure 1 B. Single-sided screw tightening, because it only tightens on one side, can also lead to uneven force on the connector, resulting in unreliable contact and affecting overall connection performance. In cases such as... Figure 1 In the double-sided screw locking method of C, due to space limitations, the screws on the outgoing side cannot be tightened with tools and can only be tightened by hand. This makes the screw torque insufficient and it is very easy to loosen after experiencing transportation vibration, which will still cause unreliable connection. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0035] Example 1:

[0036] Please see the appendix Figure 2 The eccentric, angled military cable assembly of this application includes a cable component and a locking connection component 2.

[0037] The cable component includes a connector 11 and a coaxial cable 12, with the connector 11 and the coaxial cable 12 electrically connected. The locking connection component 2 includes an injection mold body 21 and a locking member 22. The injection mold body 21 is wrapped around the connection area between the coaxial cable 12 and the connector 11. The injection mold body 21 has a first connection end 211 and a second connection end 212. The coaxial cable 12 passes through the first connection end 211, and the connector 11 passes through the second connection end 212. The locking member 22 passes through both sides of the second connection end 212, and the central axis of the locking member 22 is offset from the central axis of the first connection end 211.

[0038] The injection mold 21 refers to a composite structure formed by injection molding, which eliminates the relative displacement between the cable and the connector 11 by curing the connection area. The misalignment of the central axis means that the axis of the locking member 22 and the cable outlet direction of the coaxial line 12 are arranged in a non-collinear layout.

[0039] In this embodiment, when the locking member 22 passes through both sides of the second connecting end 212, the double-sided threaded structure 223 can simultaneously apply a balanced locking force, eliminating torque deviation from unilateral locking. Because the axis of the locking member 22 is offset from the central axis of the first connecting end 211, the upper end of the locking member 22 forms a spatial clearance area with the coaxial line 12's outgoing direction, allowing the tool's operating space to be unrestricted, increasing the operability of the locking tool, and ensuring that the locking torque meets standard requirements. Furthermore, the injection mold body 21's enclosure of the connecting area constrains the relative movement of the cable and connector 11. The positioning of the first connecting end 211 on the coaxial line 12 and the positioning of the second connecting end 212 on the connector 11 form a double fixation, maintaining the stability of the electrical connection under vibration.

[0040] This solution utilizes locking elements 22, which are installed on both sides of the second connecting end 212, to achieve balanced application of locking torque on both sides, optimize the force distribution at both ends of the connector 11, and solve the problem of uneven force distribution during unilateral locking. Furthermore, by misaligning the central axis of the locking element 22 with the central axis of the first connecting end 211, the locking element 22 has sufficient space to be secured with tools, ensuring that the required torque is achieved and reliable locking is realized on both sides, effectively improving connection stability. In addition, the integrated encapsulation of the injection mold body 21, compared to traditional split-type fixing structures, effectively absorbs mechanical vibration energy, preventing fretting wear at the junction of the connector 11 and the cable, significantly improving vibration resistance, and ensuring the connection reliability of military equipment under complex operating conditions.

[0041] In some embodiments, the central axis of the locking member 22 coincides with the central axis of the connector 11.

[0042] Specifically, the locking element 22 is configured as a symmetrical structure extending through both sides of the injection mold body 21. When the central axis of the locking element 22 coincides with the central axis of the connector 11, the axial pressure generated by the tightening operation is evenly distributed along the central axis of the connector 11. During the tightening process, the tightening torque on both sides is balanced and transmitted to the contact interface between the connector 11 and the mating parts, eliminating the bending moment effect caused by unilateral tightening. Under vibration conditions, the symmetrically distributed tightening force forms a self-balancing constraint, suppressing the relative displacement between the connector 11 and the mating parts caused by inertia.

[0043] The coaxial design automatically aligns the locking forces on both sides with the center of connector 11, achieving mechanical symmetry. This solves the problem of uneven force distribution and unreliable contact on connector 11 caused by unilateral force on locking element 22, ensuring that the contact pressure is evenly distributed around connector 11 and preventing local contact failure. Simultaneously, it suppresses relative displacement of the connection interface under vibration, improving the long-term stability of cable assembly connections in military equipment systems.

[0044] In some embodiments, please refer to the appendix. Figure 3 The injection mold body 21 has a first surface 213 and a second surface 214 opposite to each other. The first surface 213 is connected to the first connecting end 211 and is inclined towards the second surface 214.

[0045] Specifically, when the connector 11 is assembled with the coaxial line 12, the inclined setting of the first surface 213 causes the first connecting end 211 to spatially deflect from the axis of the injection mold body 21, further increasing the space between the first connecting end 211 and the locking member 22 opposite to it, making it easier to operate the locking member 22 with tools and ensuring sufficient torque.

[0046] In some embodiments, the angle formed between the plane extending from the first surface 213 and the plane extending from the second surface 214 is any value between 45° and 65°.

[0047] The included angle between the planes extending from the first surface 213 and the second surface 214 refers to the geometric relationship in space between the two opposing surfaces of the injection mold 21. This relationship can be achieved through the inclined cavity design of the injection mold or machining. This angle range is designed to be a critical value that balances the contact area and stress distribution. The inclined arrangement of the first surface 213 towards the second surface 214 is configured to form a progressive support structure, which can be achieved using an asymmetric mold forming process, creating a gradient stress interface between the connector 11 and the mold.

[0048] This setting ensures that the tilt angle of the injection mold body 21 structure guarantees the operating space for the locking component 22 during installation, and ensures sufficient torque so that the locking component 22 can be fixed perpendicular to the direction of force, thus ensuring that the cable assembly maintains stable electrical connection performance during the transportation of military equipment.

[0049] In some embodiments, the height of the injection mold body 21 is 1.5-2.5 times the height of the locking member 22.

[0050] The height of the injection mold body 21 refers to the overall dimension of the mold body in the vertical direction, which can be achieved by injection molding process. The molding dimension is controlled by adjusting the mold parameters. This dimension setting is used to construct a three-dimensional wrapping structure for the locking part 22.

[0051] By setting the height of the injection mold 21 as described above, not only can sufficient encapsulation volume be formed inside the injection mold 21, allowing the mechanical stress transmitted by the locking member 22 to be evenly absorbed by the mold material, thus avoiding stress concentration and deformation of the connection area; it can also correspondingly increase the operating space between the locking member 22 and the first connection end 211, enabling easy control of the locking member 22, ensuring that the locking member 22 provides sufficient torque, and guaranteeing connection stability.

[0052] Example 2:

[0053] The difference between this embodiment and Embodiment 1 is that, please refer to... Figures 4-5 In this embodiment, the injection mold body 21 includes an inner mold 215, a shielding layer, and an outer mold 216. The shielding layer is wrapped around the inner mold 215, and the outer mold 216 is wrapped around the shielding layer and the inner mold 215.

[0054] The inner mold 215 refers to the insulating base layer surrounding the connection area between the coaxial cable 12 and the connector 11. It can be injection molded from polyurethane material and is used to fix the cable position and provide primary protection. The shielding layer is the electromagnetic isolation structure covering the outer surface of the inner mold 215. It can be implemented using spirally wound copper foil or a metal braided layer and is used to block the influence of external electromagnetic interference on the transmission of the coaxial cable 12. The outer mold 216 refers to the outermost structure surrounding the shielding layer. It can be injection molded from nylon material and is used to protect the shielding layer from mechanical damage and enhance the overall structural strength.

[0055] In this embodiment, the inner mold 215 is first injection molded to form a basic fixation at the junction of the coaxial cable 12 and the connector 11. Then, copper foil is continuously wound around the surface of the inner mold 215 to form a fully enclosed shielding layer. Finally, a dense nylon protective layer is formed on the outer layer through secondary injection molding. The double-layer injection molding structure of the inner mold 215 and the outer mold 216 completely encloses the shielding layer internally, preventing the copper foil from oxidizing and peeling off, and improving the tensile strength of the component through the high mechanical strength of the nylon material. The shielding layer forms a continuous electromagnetic shielding ring through the metallic conductivity, effectively isolating external high-frequency signals from interfering with the internal transmission of the coaxial cable 12.

[0056] This solution combines electromagnetic shielding with mechanical protection through a three-layer composite structure, achieving comprehensive electromagnetic shielding protection for the cable connection area and effectively suppressing external interference during signal transmission. At the same time, the composite structure of the outer mold 216 and the inner mold 215 enhances the component's vibration resistance and structural stability in complex environments, avoiding performance degradation caused by the exposure of the shielding layer.

[0057] In some embodiments, see Figure 6 The injection mold body 21 is provided with a locking member 22 in the connection hole; the locking member 22 includes an operating handle 221 and a connecting rod 222, the connecting rod 222 passes through the connection hole, and the outer surface of the end of the connecting rod 222 away from the operating handle 221 is provided with a thread 223; the size of the operating handle 221 is larger than the size of the connection hole.

[0058] The connecting hole refers to the through hole on the injection mold body 21 for installing the locking element 22. Specifically, it can be symmetrically arranged on both sides of the mold body using metal insert injection molding, providing a positioning reference and support structure for the connecting rod 222. The operating handle 221 refers to the operating part of the locking element 22, which can be hexagonal or knurled cylindrical, increasing the operating contact area to facilitate the application of rotational torque. The connecting rod 222 is the rod-shaped component connecting the operating handle 221 and the threaded section 223. It can be integrally machined from stainless steel, used to transmit rotational torque and withstand axial tensile force. The thread 223 refers to the external thread 223 structure located at the end of the connecting rod 222, which can be a standard metric thread 223 or a self-locking thread 223, used to engage with the external connection structure to generate locking force. The size of the operating handle 221 being larger than the connecting hole means that the radial dimension of the operating handle 221 exceeds the diameter of the connecting hole. Specifically, a flange structure with a diameter larger than the inner diameter of the hole can be used to physically limit the operating handle 221 from being completely embedded in the hole, while providing sufficient operating area.

[0059] Specifically, the connecting holes are symmetrically located on both sides of the injection mold body 21, providing precise installation positioning for the connecting rod 222. During the locking operation, the operating handle 221 is rotated, causing the connecting rod 222 to rotate as well. The threaded section 223 at its end engages with the external connecting structure. Because the operating handle 221 is larger than the connecting holes, the operator can control its rotation to apply sufficient locking torque. The connecting rod 222 generates axial displacement during rotation, and the rotational torque is converted into axial locking force through the threaded engagement of the thread 223, achieving simultaneous locking on both sides. The overall operation is simple and convenient, effectively ensuring connection stability.

[0060] In some embodiments, the outer surface of the operating handle 221 is provided with anti-slip texture 224.

[0061] Among them, the anti-slip texture 224 refers to the regular or irregular concave and convex texture structure set on the surface of the operating handle 221. Specifically, it can be achieved by knurling or embossing processes, which increases the friction coefficient of the contact surface to enhance grip stability.

[0062] Specifically, the anti-slip texture 224 alters the contact state between the operating handle 221 and the tool through its physical structure, creating multi-point contact and a micro-engaging effect when the locking member 22 is rotated. When a rotational torque is applied, the uneven structure of the anti-slip texture 224 effectively resists slippage, thus preventing torque transmission failure due to a smooth surface. This structural design directly acts on the operating end of the locking member 22, ensuring that the preset tightening torque can still be achieved when operating in a confined space, and ensuring that the locking member 22 maintains a stable tightening state under vibration, thereby improving the long-term reliability of the cable assembly connection interface.

[0063] Example 3:

[0064] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 7 In this embodiment, the outer surface of the first connecting end 211 is provided with buffer grooves 217 at even intervals.

[0065] Among them, the buffer groove 217 refers to the groove structure set on the outer surface of the first connecting end 211, which can be realized by machining or injection molding process. Its function is to absorb the impact energy transmitted to the connecting part by external vibration through local structural deformation.

[0066] Specifically, when the cable assembly is subjected to external vibration or mechanical stress, the buffer groove 217 structure can form an elastic buffer area through its own deformation, dispersing the impact energy transmitted to the connection point into multiple buffer groove 217 units. The uniformly spaced arrangement makes the stress distribution regular, avoiding excessive stress accumulation due to local rigidity differences. The geometric structure of the buffer groove 217 changes the rigidity distribution state of the surface of the first connection end 211, forming a gradient buffering effect while maintaining the strength of the main structure, thereby reducing the risk of structural fatigue.

[0067] In some specific embodiments, the depth of the buffer groove 217 can be one-third to one-half of the wall thickness of the connection end, and the shape can be U-shaped or V-shaped. The spacing of the buffer grooves 217 can be adjusted according to the cable diameter; for example, the spacing between adjacent grooves is 1.5 to 3 times the width of the groove.

[0068] This application can effectively reduce the stress peak of the first connection end 211 under dynamic load, prevent material fatigue fracture caused by long-term vibration, improve the durability of the first connection end 211, and ensure the normal use of coaxiality.

[0069] In some embodiments, the first connecting end 211 protrudes by 8-15mm. By setting the length of the first connecting end 211, the outgoing wire of the coaxial cable 12 is protected by the first connecting end 211, reducing the bending moment damage to the coaxial cable 12 during the operation of the cable assembly, providing a buffer function for the outgoing wire of the coaxial cable 12, and effectively improving the protection of the coaxial cable 12.
