Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of each connecting element with two or two or more separated connecting positions for or possibly for interconnecting conductive parts, and particularly relates to a cable connector. BACKGROUND

[0002] Power transmission lines are important power facilities, and when erecting transmission lines and repairing disconnected transmission lines, wire connection is needed, and in actual operation, cable connectors are usually used to connect wires. A general cable connector (also known as a wire connector) includes a sleeve, a wire clamp, and an elastic member. Since the sleeve wall is closed, the user cannot accurately determine the distance of the wire inserted into the sleeve. If the wire is inserted into the sleeve for a short distance, the wire may come out of the sleeve during later use.

[0003] To solve the above problems, the prior art such as a patent number ZL201820056207.4 (publication number CN207765629U) discloses a wire connector capable of determining the insertion distance of the wire in the sleeve. The middle part of the sleeve is limited by two transmission members, and the two transmission members are connected by an elastic member. The sleeve wall is provided with a window corresponding to the movement range of the transmission member. During use, the end of the wire inserted into the sleeve pushes the transmission member to move, and the movement position of the transmission member in the window is observed to determine whether the wire is inserted into the sleeve. This avoids the phenomenon that the wire comes out due to a short insertion distance. However, the position of the wire acting on the transmission member is uncertain after the wire is inserted into the sleeve. When the wire only acts on one side of the transmission member, the transmission member is inclined as a whole and rubs against the inner wall of the sleeve. The transmission member may be stuck in the sleeve and cannot move, affecting the use of the cable connector and the accurate display of the wire insertion position. SUMMARY

[0004] The utility model solves the technical problem of the prior art, provides a cable connector that can indicate that the wire is inserted into the sleeve and ensure the stability of the transmission member, and avoid the transmission member being stuck in the sleeve.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows: the cable connector that can be installed in place includes:

[0006] The sleeve has an axially extending wire hole.

[0007] The wire clamp is arranged in the sleeve.

[0008] Further characterized in that it further includes:

[0009] A transmission member is arranged in the wire hole of the sleeve axially and movably, and the transmission member is arranged at the inner end of the wire clamp;

[0010] A driven member is arranged in the wire hole of the sleeve radially and movably, and the driven member comprises a radially extending protrusion;

[0011] A second through hole is arranged on the sleeve wall, and the protrusion is arranged in the second through hole;

[0012] The driven member and the transmission member are in inclined surface transmission cooperation, and the driven member moves radially outward based on the axial inward movement of the transmission member.

[0013] In order to improve the accuracy of the wire acting on the position of the transmission member, further, an acting groove facing the opening of the wire clamp is arranged on the end face of the transmission member close to the outer end of the wire clamp, and the cross section of the acting groove is in a trumpet shape. When the wire is close to the transmission member, the wire can slide along the groove wall to the groove bottom of the acting groove, and the trumpet-shaped distribution of the cross section of the acting groove also increases the probability of the wire entering the acting groove.

[0014] In order to facilitate the radial movement of the driven member, from the perspective of simple structure, preferably, the driven member is arranged at the inner end of the transmission member, the driven member comprises a base body, the protrusion is arranged on the base body, and a first inclined surface facing the transmission member and inclined relative to the axial direction is formed on the base body;

[0015] A second inclined surface inclined relative to the axial direction and matched with the first inclined surface in transmission is formed on the transmission member. When the wire pushes the transmission member to move axially into the sleeve, the transmission member applies force to the second inclined surface through the first inclined surface, the driven member moves radially outward along the second inclined surface, and the protrusion is exposed to the second through hole.

[0016] In order to improve the stability of the axial movement of the transmission member, further, a limiting sliding groove guiding the movement direction of the transmission member is arranged in the sleeve, and a sliding bar matched with the limiting sliding groove is arranged on the transmission member. The sliding cooperation relationship between the limiting sliding groove and the sliding bar can limit the movement of the transmission member.

[0017] The extension direction of the limiting sliding groove can be parallel to the central axis of the sleeve and axially outward, or can be axially inclined. In order to increase the sensitivity of the movement of the driven member, preferably, the extension direction of the limiting sliding groove is inclined relative to the axial direction, and the included angle between the extension direction of the limiting sliding groove and the radial outward movement direction of the driven member is obtuse, and the sliding bar is matched with the extension direction of the limiting sliding groove. This technical solution makes the transmission member have a displacement in the radial direction outward of the second through hole while moving axially inward, and increases the displacement distance of the radial outward movement of the driven member under the condition that the axial inward displacement distance of the transmission member is the same.

[0018] To further improve the stability of the transmission component's movement, the sleeve is further provided with mounting plates on both sides of the transmission component. The limiting groove is provided on the mounting plates, and a sliding part is formed at the inner end of the transmission component. The slide bar protrudes from the sliding part. The mounting plates limit the movement of the transmission component between the two mounting plates.

[0019] To prevent direct collision between the actuating groove and the mounting plate, the transmission component further features a lateral protrusion forming a limiting portion at the junction between the sliding part and the actuating groove. The lateral width of the limiting portion is greater than the distance between the two mounting plates. When the wire pushes the transmission component to move axially inward, the deepest movement position of the transmission component is when the limiting portion abuts against the outer end of the mounting plate.

[0020] Furthermore, the transmission component, driven component, and mounting plate are mounted within the wire hole via a mounting base. The mounting base facilitates modular installation of the transmission component, driven component, and mounting plate, improving installation convenience.

[0021] To facilitate the operator's placement of the transmission component within the mounting base, the transmission component further includes a third inclined surface at its second end, opposite to the driven component. The mounting base contains a guide component located between two mounting plates. This guide component corresponds to the second end and has a fourth inclined surface formed on its opposite side. The inclination angle of the fourth inclined surface matches that of the third inclined surface and the slide bar. The sliding engagement between the third and fourth inclined surfaces between the transmission component and the guide component provides auxiliary guidance for the axial movement of the transmission component.

[0022] To facilitate repeated use of the cable connector, an elastic element is further provided between the transmission component and the bottom wall of the mounting base. This elastic element tends to spring against the cable clamp and compress the transmission component. The elastic element allows the transmission component to quickly return to its original position.

[0023] Compared with the prior art, the advantages of this utility model are as follows: The transmission component of this utility model is axially located inside the wire hole, and the driven component and the transmission component are engaged in inclined transmission. When threading the wire, the driven component can move radially based on the axial movement of the transmission component, and then protrude out of the sleeve to indicate that the wire is threaded in place. During the threading process, the movement trajectory of the transmission component and the driven component is highly stable, and it is not easy for them to tilt and get stuck in the sleeve, ensuring the accuracy of the display of the wire threading information and avoiding the phenomenon of the wire coming out due to a short wire insertion distance.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] like Figures 1-12 The diagram shows the preferred embodiment of this utility model. This embodiment features a cable connector that can be identified and installed in place, primarily used for connecting two wires or a wire to an electrical appliance. Existing cable connectors have a transmission element and a viewing window within the sleeve to indicate the wire insertion depth. However, when the wire extends into the sleeve, the position acting on the transmission element is difficult to determine. This can cause the transmission element to tilt to one side and become stuck inside the sleeve when the wire only acts on one side, hindering the connection action. Therefore, it would be beneficial to provide a cable connector that avoids the transmission element getting stuck inside the sleeve. The detailed structure of this cable connector will be described below:

[0038] See Figures 1-6The cable connector that can be identified and installed in this embodiment includes a sleeve 1, a wire clamp 2, a transmission member 3, and a driven member 4. The sleeve 1 has an axially extending wire hole 11. The wire clamp 2 is disposed inside the sleeve 1. The transmission member 3 is axially movable within the wire hole 11 of the sleeve 1, and is located at the inner end of the wire clamp 2. The driven member 4 is radially movable within the wire hole 11 of the sleeve 1, and includes a radially extending protrusion 41. A second through hole 12 is provided on the wall of the sleeve 1, and the protrusion 41 is fitted through the second through hole 12. The driven member 4 and the transmission member 3 are engaged by a beveled transmission mechanism, and the driven member 4 moves radially outward based on the axial inward movement of the transmission member 3. Additionally, outwardly flared connectors 9 are connected to both ends of the sleeve 1 to facilitate the insertion of the wire a by the user. In this embodiment, when the cable connector is used to connect two wires, the wire hole 11 inside the sleeve 1 is axially through, and two sets of wire clamps 2, transmission components 3, and driven components 4 are symmetrically arranged inside the sleeve 1. The connection of the two wires inside the sleeve 1 is achieved based on the symmetrical two sets of wire clamps 2, transmission components 3, and driven components 4. The cable connector can also be provided with only one wire, and the wire hole 11 is not through. In this case, the wire a is placed inside the sleeve 1, and the electrical connection end is located on the bottom wall of the sleeve 1. The bottom wall of the sleeve 1 is an electrical conductor, which is suitable for this application, and the connection of the wire at the connection end is achieved.

[0039] See Figure 4 , Figure 6 , Figure 9 , Figure 10 The transmission component 3 has an operating groove 32 on its outer end face near the wire clamp 2, which opens towards the wire clamp 2. The operating groove 32 has a trumpet-shaped cross-section. When the wire a approaches the transmission component 3, it can slide along the groove wall of the operating groove 32 to the bottom of the groove. The trumpet-shaped cross-section of the operating groove 32 also increases the probability of the wire a entering the operating groove 32, thus improving the accuracy of the operating position of the wire a on the transmission component 3.

[0040] See Figure 8 The driven member 4 is disposed at the inner end of the transmission member 3. The driven member 4 includes a base and a protrusion 41 disposed on the base. A first inclined surface 42 is formed on the base, facing the transmission member 3 and inclined relative to the axial direction. A second inclined surface 31 is formed on the transmission member 3, inclined relative to the axial direction and matching the first inclined surface 42 for transmission. When the wire a pushes the transmission member 3 axially into the sleeve 1, the transmission member 3 applies force to the second inclined surface 31 through the first inclined surface 31. The driven member 4 moves radially outward along the second inclined surface 31. The protrusion 41 is exposed in the second through hole 12, which facilitates the radial movement of the driven member 4.

[0041] See Figure 4 , Figures 9-12The sleeve 1 is provided with a limiting groove 51 to guide the movement direction of the transmission component 3, and the transmission component 3 is provided with a slide bar 331 that matches and is inserted into the limiting groove 51. The sliding fit between the limiting groove 51 and the slide bar 331 can limit the movement of the transmission component 3, thereby improving the stability of the axial movement of the transmission component 3.

[0042] The extension direction of the limiting slide groove 51 can be parallel to the central axis of the sleeve 1 and axially outward, or it can be axially inclined. In order to increase the sensitivity of the follower 4's movement, the extension direction of the limiting slide groove 51 in this embodiment is inclined relative to the axial direction, and the angle between the extension direction of the limiting slide groove 51 and the radial outward movement direction of the follower 4 is an obtuse angle. The slide bar 331 is matched with the extension direction of the limiting slide groove 51. This technical solution enables the transmission member 4 to have a radial displacement outward in the second through hole 12 while moving axially inward, thereby increasing the radial outward displacement distance of the follower 4 under the condition that the axial inward displacement distance of the transmission member 4 is the same.

[0043] See Figure 11 and Figure 12 The sleeve 1 has mounting plates 5 on both sides of the transmission component 3. A limiting groove 51 is provided on the mounting plate 5. The inner end of the transmission component 3 forms a sliding part 33, and a slide bar 331 protrudes from the sliding part 33. The mounting plates 5 limit the movement of the transmission component 3 between the two mounting plates 5, further improving the stability of the movement of the transmission component 4.

[0044] The transmission component 3 has a lateral protrusion forming a limiting part 34 at the junction between the sliding part 33 and the actuating groove 32. The lateral width of the limiting part 34 is greater than the distance between the two mounting plates 5. When the wire a pushes the transmission component 3 to move axially inward, the deepest moving position of the transmission component 3 is when the limiting part 34 abuts against the outer end of the mounting plate 5, preventing direct collision between the actuating groove 32 and the mounting plate 5. In addition, the transmission component 3, the driven component 4, and the mounting plate 5 are disposed in the wire hole 11 through the mounting base 6. The peripheral wall of the mounting base 6 has a third through hole 61 that communicates with the second through hole 12. The lower surface of the base slides in contact with the upper surface of the bottom wall of the mounting base 6. The mounting base 6 facilitates the modular installation of the transmission component 3, the driven component 4, and the mounting plate 5, improving installation convenience.

[0045] See Figure 4 and Figure 7The transmission component 3 has a third inclined surface 35 formed at its second end opposite to the driven component 4. A guide component 7 is provided within the mounting base 6, located between two mounting plates 5. The guide component 7 corresponds to the second end and has a fourth inclined surface 71 formed on its opposite side. The inclination angle of the fourth inclined surface 71 matches that of the third inclined surface 35 and the slide bar 331. The sliding engagement between the third inclined surface 35 and the fourth inclined surface 71 between the transmission component 3 and the guide component 7 provides auxiliary guidance for the axial movement of the transmission component 3. During the assembly of the cable connector, the installer adjusts the transmission component 3 so that the third inclined surface 35 and the fourth inclined surface 71 are opposite each other, and then slides the transmission component 3 between the two mounting plates 5 along the fourth inclined surface 71, facilitating the installation of the transmission component 3 within the mounting base 6.

[0046] See Figure 11 and Figure 12 An elastic element 8 is provided between the transmission component 3 and the bottom wall of the mounting base 6. The elastic element 8 tends to press the transmission component 3 against the wire clamp 2. The elastic element 8 allows the transmission component 3 to quickly reset, facilitating repeated use of the cable connector by the user.

[0047] The working principle of the cable connector in this embodiment is as follows: The user inserts the wire a into the sleeve 1 through the connector 9, passes through the wire clamp 2 and extends into the middle of the wire hole 11, and drives the wire clamp 2 to move towards the middle of the wire hole 11, applying force to the action groove 32. The transmission member 3 moves axially into the sleeve 1 along the limiting slide groove 51 and the fourth inclined surface 71, and the elastic member 8 is compressed. At the same time, due to the inclined surface transmission cooperation of the first inclined surface 42 and the second inclined surface 31, the driven member 4 moves radially outward, and the protrusion 41 is exposed in the second through hole 12. After the user sees the protrusion 41 exposed, it means that the wire has been inserted into the sleeve 1 in place, and the user can stop inserting the wire a. The wire clamp 2 clamps the wire a, and the connection action of the wire a is completed.

[0048] In this invention, the transmission component 3 is axially positioned inside the wire hole 11. The driven component 4 engages with the transmission component 3 via an inclined transmission mechanism. During wire threading, the driven component 4 can move radially based on the axial movement of the transmission component 3, thereby protruding from the sleeve 1 to display the information that the wire has been threaded in place. During the threading process, the movement trajectory of the transmission component 3 and the driven component 4 is highly stable, and it is not easy for them to tilt and get stuck in the sleeve 1, thus ensuring the accuracy of the information display of the wire a being threaded in place and avoiding the phenomenon that the wire a may come out due to a short insertion distance.
