Adapter structure with tensile function

Abstract

This utility model relates to a tensile-resistant adapter structure, comprising a first adapter end and a second adapter end. The first adapter end includes a first connecting sleeve and a wire clamping sleeve, and the second adapter end includes a second connecting sleeve and a wire clamping sleeve. The wire clamping sleeve is tensile-resistantly connected to the first / second connecting sleeve. The front ends of the first and second connecting sleeves are detachably tensile-resistantly connected. The wire clamping sleeve is tensile-resistantly connected to the cable at its corresponding end. This utility model provides tensile-resistant connections between the two adapter ends and between each adapter end and its corresponding cable. When the cables are pulled at both ends, the force is not transmitted to the intermediate adapter point, ensuring the tensile resistance of the adapter point. Simultaneously, the adapter point is completely enclosed within the adapter structure, preventing bending of the internal adapter point during subsequent installation and use, thus ensuring the adapter point is not affected by bending.

Description

Technical Field

[0001] This utility model belongs to the field of cable assembly transition technology, specifically designing a transition structure with tensile strength. Background Technology

[0002] After the transition is completed in the cable assembly, the transition point is usually marked after heat shrink tubing, potting or other protective treatments to remind that bending is prohibited. However, this area is not tensile, not sealed, and has poor shielding effect. In actual use, this area will still be subjected to tension and bending, which will cause damage to the transition point.

[0003] To solve this problem, sometimes the conversion function is achieved by adding an adapter box or adding one or more sets of plugs / sockets. However, this method can only provide space for conversion and cannot achieve tensile strength at the conversion point. In addition, some structures that realize the conversion function also need to add a printed circuit board for conversion, which takes up a lot of space. In some space-constrained situations, the above-mentioned structures that realize the conversion function cannot even be used. Summary of the Invention

[0004] To solve the above problems, this utility model provides a transition structure with tensile strength, which not only meets the requirement that the transition point does not bend, but also meets the tensile strength requirement of the transition point.

[0005] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a tensile-resistant adapter structure includes a first adapter end and a second adapter end. The first adapter end includes a first connecting sleeve 1 and a wire clamping sleeve 3, and the second adapter end includes a second connecting sleeve 2 and a wire clamping sleeve 3. The wire clamping sleeve is tensile-resistantly connected to the first connecting sleeve 1 / second connecting sleeve 2; the front ends of the first connecting sleeve 1 and the second connecting sleeve 2 are detachably tensile-resistantly connected; and the wire clamping sleeve is tensile-resistantly connected to the cable at its corresponding end.

[0006] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0007] The aforementioned adapter structure with tensile strength is further sealed between the first connecting sleeve 1 and the second connecting sleeve 2 by a first sealing ring 9.

[0008] The aforementioned adapter structure with tensile strength is further sealed by a second sealing ring 12 between the wire clamp sleeve and the first connecting sleeve 1 or the second connecting sleeve 2.

[0009] In the aforementioned adapter structure with tensile strength, the clamp sleeve and the cable are further sealed by a third sealing ring 13.

[0010] In the aforementioned adapter structure with tensile strength, the third sealing ring 13 is fitted around the outer periphery of the cable, and its front end is blocked by the first connecting sleeve 1 or the second connecting sleeve 2. The tapered surface of its rear end, which gradually shrinks radially from front to back, cooperates with the tapered surface of the inner periphery of the clamping sleeve for sealing.

[0011] In the aforementioned adapter structure with tensile strength, the cable clamp sleeve achieves a tensile connection with the cable through two relatively fixed pressure plates at its tail.

[0012] In the aforementioned adapter structure with tensile strength, the cable is a shielded cable. The outer sheath of the shielded cable at the first adapter end is pressed and fixed to the tail of the first connecting sleeve 1 by a shielding ring 11, and the outer sheath of the shielded cable at the second adapter end is pressed and fixed to the tail of the second connecting sleeve 2 by a shielding ring 11. Both the first connecting sleeve 1 and the second connecting sleeve 2 are conductive structures.

[0013] The aforementioned adapter structure with tensile strength features a tensile connection achieved by locking the first connecting sleeve 1 and the second connecting sleeve 2 with threads.

[0014] The aforementioned adapter structure with tensile strength is wherein the clamping sleeve and the first connecting sleeve 1 / second connecting sleeve 2 are threadedly connected.

[0015] The aforementioned adapter structure with tensile strength forms a space that can accommodate multiple sets of wires for connection after the front ends of the first connecting sleeve 1 and the second connecting sleeve 2 are joined together, so that multiple connections can be achieved in one space.

[0016] Compared with the prior art, this utility model has significant advantages and beneficial effects. Through the above technical solution, this utility model achieves considerable technological advancement and practicality, and has broad industrial application value. It possesses at least the following advantages:

[0017] The adapter structure of this utility model is a split type. When multiple adapters are required, the middle part of the adapter structure is larger and the two ends are thinner. Before the adapter is completed, the split structure is located on different cables. It has very low requirements for operating space and is extremely convenient to operate, enabling rapid adapter operation.

[0018] The adapter structure of this utility model has seals at each connection point, ensuring the seal between the two adapter ends, inside the adapter ends, and between the adapter structure and the cable.

[0019] When the cable is a shielded cable, the cable shield is squeezed tightly onto the shielded connecting sleeve by a shielding pressure ring to ensure continuity between shields and 360° full shielding conduction, and to ensure the full shielding effectiveness at the junction.

[0020] This utility model features tensile-resistant connections between the two adapter ends and between each adapter end and its corresponding cable. The adapter end and the cable are pressed together by a pressure plate. When the cable is pulled at both ends, the force is not transmitted to the middle adapter point, thus ensuring the tensile resistance of the adapter point.

[0021] The entire junction of this utility model is enclosed inside the junction structure, ensuring that the junction will not be bent during subsequent installation and use, and guaranteeing that the junction will not be affected by bending. Attached Figure Description

[0039] To further illustrate the technical means and effects adopted by this utility model to achieve the intended purpose of the invention, the following detailed description of the specific implementation, structure, features and effects of the tensile-resistant adapter structure proposed according to this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0040] Please see Figure 1-3 This is a schematic diagram of the various parts of the adapter structure with tensile strength of this utility model. The adapter structure includes a first connecting sleeve 1 and a second connecting sleeve 2 extending in the left-right direction. The front ends of the first connecting sleeve 1 and the second connecting sleeve 2 are detachably tensile connected. The front ends of the first connecting sleeve 1 and the second connecting sleeve 2 each have a cavity for accommodating the cable adapter part. The front ends of the first cable 5 inserted from the tail of the first connecting sleeve 1 and the second cable 6 inserted from the tail of the second connecting sleeve 2 can be used for adapter operation within the front cavity of the first connecting sleeve 1 or the second connecting sleeve 2, or can extend out of the front cavity of the first connecting sleeve 1 and the second connecting sleeve 2 for adapter operation. After the adapter operation is completed, the adapter part is placed in the front cavity of the first connecting sleeve 1 or the second connecting sleeve 2, and then the tensile connection of the front ends of the first connecting sleeve 1 and the second connecting sleeve 2 is used to protect the adapter part.

[0041] The first connecting sleeve 1 is further provided with a first wire clamping sleeve 3 at its tail end, and the second connecting sleeve 2 is connected to a second wire clamping sleeve 4 at its tail end. The first wire clamping sleeve 3 and the first connecting sleeve 1 are axially tensile connected, and the second wire clamping sleeve 4 and the second connecting sleeve 2 are tensile connected. The first wire clamping sleeve 3 clamps the outer sheath of the first cable 5 through a first wire clamp 7 at its tail end, and the second wire clamping sleeve 4 clamps the outer sheath of the second cable 6 through a second wire clamp 8 at its tail end, thereby achieving tensile connections with the first cable 5 and the second cable 6, respectively.

[0042] In this embodiment, the front ends of the first connecting sleeve 1 and the second connecting sleeve 2 are detachably tensile-resistantly connected by threaded locking. Specifically, the outer periphery of the front end of the first connecting sleeve 1 is provided with external threads, and the inner periphery of the front end of the second connecting sleeve 2 is provided with internal threads. The two are threadedly locked by relative tightening. Furthermore, the outer periphery of the first connecting sleeve 1 is also provided with a first sealing ring 9, which can achieve a seal between the first connecting sleeve 1 and the second connecting sleeve 2. Specifically, the outer periphery of the first connecting sleeve 1 has a small-diameter section with external threads, and the end of the small-diameter section has a groove. The first sealing ring 9 is located in the groove, and one side wall of the groove is a first stepped surface 10 formed by the radial dimension change of the outer periphery of the first connecting sleeve 1 due to the smaller front and larger rear. The inner circumference of the front end of the second connecting sleeve 2 is provided with an annular groove, and the inner wall of the annular groove is provided with an internal thread. When the first connecting sleeve 1 and the second connecting sleeve 2 are locked by the thread, the first sealing ring 9 is pressed between the first connecting sleeve 1 and the second connecting sleeve 2 to achieve radial sealing between the two. At the same time, the first sealing ring 9 is also tightly fitted with the first stepped surface 10 of the outer circumference of the first connecting sleeve 1 towards the second connecting sleeve under the axial push of the second connecting sleeve 2, thereby achieving axial sealing between the first connecting sleeve 1 and the second connecting sleeve 2.

[0043] In this embodiment, the portion of the first connecting sleeve 1 with external threads on its outer periphery is defined as the small-diameter section, and the portion located behind the small-diameter section is defined as the main body section. A large-diameter section is also located behind the main body section, and the tail of the large-diameter section connects to the pressure section. From the small-diameter section to the large-diameter section, the outer diameter of the first connecting sleeve 1 gradually increases, while the outer diameter of the pressure section is smaller than that of the small-diameter section. From the small-diameter section to the large-diameter section, the first connecting sleeve 1 has the same inner diameter, while the pressure section has an inner diameter much smaller than that of the small-diameter section. The inner hole of the pressure section is used for the passage of the conductor inside the first cable 5, and its outer periphery is used to press and fix the aramid layer of the first cable 5. The second connecting sleeve 2 differs from the first connecting sleeve 1 only in that the front end of the second connecting sleeve 2 has an internal thread structure that locks with the front thread of the first connecting sleeve 1. The other parts of the structure of the second connecting sleeve 2 are completely the same as those of the first connecting sleeve 1, but their dimensions may not be completely the same; for example, the dimensions of the inner holes of the pressure sections of the first connecting sleeve 1 and the second connecting sleeve 2 may be different.

[0044] Both the first connecting sleeve 1 and the second connecting sleeve 2 have a shielding ring 11 on the outer periphery of the pressure section at their tail ends for shielding the aramid layer of the cable. In this embodiment, the outer periphery of the pressure section is stepped, gradually decreasing from front to back. The shielding ring 11 also has a tapered hole with an inner diameter that gradually increases from front to back. In other embodiments, the outer diameter of the pressure section can remain unchanged, and the outer periphery has several spaced annular grooves to enhance the contact force between the aramid layer and the connecting sleeve.

[0045] In this embodiment, the first wire clamping sleeve 3 and the second wire clamping sleeve 4 have the same structure. The inner circumference of the front end is provided with an internal thread that locks with the outer circumference thread of the first connecting sleeve 1 or the second connecting sleeve 2, and the rear end is provided with two pressure plates for clamping the cable. That is, in this embodiment, the first wire clamp 7 and the second wire clamp 8 are both composed of two pressure plates that are fixed to the tail of the wire clamping sleeve.

[0046] The first wire clamping sleeve 3 and the second wire clamping sleeve 4 are respectively fitted and locked with the outer circumferential threads of the large-diameter sections of the first connecting sleeve 1 and the second connecting sleeve 2 through their front internal threads. This results in the first wire clamping sleeve 3 and the second wire clamping sleeve 4 having a stepped structure that is larger at the front and smaller at the back, both inside and out. The wire pressing section at the tail of the first connecting sleeve 1 and the second connecting sleeve 2 is located in the larger cavity at the front of the stepped structure. A second sealing ring 12 is used to achieve a seal between the first wire clamping sleeve 3 and the first connecting sleeve 1, and between the second wire clamping sleeve 4 and the second connecting sleeve 2, after thread locking. Specifically, an annular groove is provided on the outer circumference of the large-diameter section of the first connecting sleeve 1 and the second connecting sleeve 2, and the second sealing ring 12 is located within this annular groove.

[0047] The first wire clamping sleeve 3 and the second wire clamping sleeve 4 are also provided with a third sealing ring 13 for sealing with the cable. In this embodiment, the front end face of the third sealing ring 13 is stopped and limited by the rear end face of the first connecting sleeve 1 or the second connecting sleeve 2, and the outer circumference of the rear end of the third sealing ring 13 that seals with the first wire clamping sleeve 3 or the second wire clamping sleeve 4 is a tapered surface with an outer diameter that gradually increases from front to back. The inner circumference of the first wire clamping sleeve 3 and the second wire clamping sleeve 4 that seals with the third sealing ring 13 is also a tapered surface with a radial dimension that gradually increases from front to back. Thus, when the first wire clamping sleeve 3 moves forward axially relative to the first connecting sleeve 1 and locks, and the second wire clamping sleeve 4 moves forward axially relative to the second connecting sleeve 2 and locks, the tapered surfaces of the inner circumferences of the first wire clamping sleeve 3 and the second wire clamping sleeve 4 radially compress the third sealing ring 13 so that it hugs the outer circumference of the first cable 5 or the second cable 6, thereby achieving a seal with the first cable 5 or the second cable 6.

[0048] In this embodiment of the utility model, the first cable 5 and the second cable 6 are shielded cables. At this time, the first connecting sleeve 1, the second connecting sleeve 2 and the shielding pressure ring 11 are all made of conductive material. The shielding pressure ring 11 presses the shielding layer of the shielded cable against the outer periphery of the tail of the connecting sleeve, so as to achieve contact and conduction between the first connecting sleeve 1 and the second connecting sleeve 2 and the shielding layer of the shielded cable at their tail. The connection between the first connecting sleeve 1 and the second connecting sleeve 2 realizes the continuous conduction of the shielding of the two transition ends.

[0049] In this embodiment of the utility model, both the first cable 5 and the second cable 6 are multi-core cables. When they are connected, the connection points of the multiple core wires are all within the cavity formed by the mating of the first connecting sleeve 1 and the second connecting sleeve 2, so as to realize the rapid connection of the multi-core cables in the same space.

[0050] In use, the adapter structure of this utility model firstly places a first clamping sleeve 3 and a first connecting sleeve 1 on the end of the first cable 5, and a second clamping sleeve 4 and a second connecting sleeve 2 on the end of the second cable 6. Then, the first cable 5 and the second cable 6 are connected as required. After the connection is completed, the front ends of the first connecting sleeve 1 and the second connecting sleeve 2 are tightened by threads, and the two are sealed by the first sealing ring. The shielding layer stripped from the outer periphery of the first cable 5 is pressed and fixed to the outer periphery of the tail of the first connecting sleeve 1 by a shielding pressure ring, and the shielding layer of the second cable 6 is pressed and fixed to the outer periphery of the tail of the second connecting sleeve 2 by a shielding pressure ring, achieving continuous shielding between the cable and the connecting sleeve, ensuring 360° continuous shielding and conductivity at the connection point. The first clamping sleeve 3 is screwed onto the first connecting sleeve 1, and the second clamping sleeve 4 is screwed onto the second connecting sleeve 2. At this time, the second sealing ring achieves a seal between the clamping sleeve and the connecting sleeve, and the third sealing ring achieves a seal between the clamping sleeve and the cable. Finally, two pressure plates are fixed on the first and second wire clamping sleeves respectively to achieve tensile connection between the wire clamping sleeves and the cable, thereby ensuring the tensile strength of the junction.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
