Description

Technical Field

[0001] This application relates to the technical field of cable connection devices, and particularly to cable connectors.

Background Art

[0002] Cable connection devices are widely applied to various power supply devices, and realize the transmission of current or signals through cable connections.

[0003] In the prior art, commonly used cable connection methods include non-removable methods and removable methods. The non-removable method includes welding. Since welding needs to be completed in the factory and transported to the site for work, such a connection method is inconvenient for maintenance and repair, and the cost is high. That is, the convenience of the welding connection method is poor. The removable method includes bolt locks. The connection method of bolt locks requires the use of tools to lock or unlock, and has high requirements for the locking moment. If the locking moment is insufficient, poor contact is likely to occur. If the locking moment is too large, the bolt is prone to wear, the contact resistance becomes large after long-term use, the temperature rise is too high, and eventually a burning phenomenon occurs. That is, the reliability of the bolt lock connection method is poor.

[0004] Based on this, in view of the problems of poor convenience and reliability of the cable connection method in the prior art, it is necessary to provide a cable connector.

Means for Solving the Problems

[0005] The cable connector includes a casing, a connection member, a wire pressing elastic member, and a rotating member. The connection part of the connection member is provided in the casing. The wire pressing elastic member is located in the casing. The wire pressing elastic member has a pressing part. The pressing part and the connection part are arranged opposite to each other. A clamp opening for inserting a cable is formed between the pressing part and the connection part. The rotating member includes a handle and a cam structure. The cam structure is connected to one end of the handle. The cam structure is rotatably connected to the casing. The cam structure abuts against the wire pressing elastic member. The rotating member has a first position and a second position. When the rotating member is in the first position, the clamp opening presents an open state, and the cross-sectional dimension of the clamp opening is larger than the cross-sectional dimension of the cable. When the rotating member is in the second position, the clamp opening presents a pressing state, and the cross-sectional dimension of the clamp opening is smaller than the cross-sectional dimension of the cable. The connection part and the pressing part are respectively used to abut against the outer surface of the cable.

[0006] In one embodiment, the wire pressing elastic member includes an elastic body, a housing, and a sheet body. The elastic body abuts against the cam structure. One end of the elastic body is connected to the housing. The other end of the elastic body is connected to the sheet body. The sheet body is located in the housing. The connection part is located in the housing and is connected to the sheet body. The pressing part is formed on the inner wall surface of the housing on the side facing the connection part. The elastic body, the housing, and the sheet body are of an integral structure.

[0007] In one embodiment, the casing is provided with a first storage groove matching the rotating member. When the rotating member is in the first position, the rotating member is located outside the first storage groove. When the rotating member is in the second position, the rotating member is located in the first storage groove.

[0008] In one embodiment, a locking portion is further provided on the casing, a concave groove matching the locking portion is provided on the rotating member, and when the rotating member is located in the first storage groove, the locking portion is connected to the concave groove.

[0014] In one embodiment, the casing includes a first housing and a second housing, and the first housing and the second housing are removably connected.

Advantages of the Invention

[0015] The above cable connector drives the pressing part through a cam structure by the rotation of a rotating member to move it relative to the connection part, and further realizes the insertion and pressing connection of the cable. In the actual use process, when the rotating member is rotated to the first position, the cam structure drives the pressing part of the wire pressing elastic member to move away from the connection part along with the rotation of the rotating member based on the eccentric characteristics, and further gradually opens the clamping port, making it convenient to insert the end of the cable. Then, when the rotating member is rotated to the second position, the cam structure drives the pressing part of the wire pressing elastic member to move towards the side approaching the connection part, and further gradually closes the clamping port, realizing the return by the elastic force of the wire pressing elastic member, and pressing the end of the cable against the connection part by the pressing part to complete the pressing connection of the cable. When it is necessary to remove the cable, rotating the rotating member to the first position allows the cable to be pulled out. Compared with the cable connection method in the prior art, the present application conveniently realizes the connection and removal of the cable, and realizes the pressing of the cable by the elastic force method. Regardless of the locking moment in the bolt lock, the connection has good consistency and improves the connection reliability.

However, the present application can be implemented in many other forms different from the embodiments described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0018] In the description of the present application, it should be understood that terms such as "center", "longitudinal direction", "lateral direction", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial direction", "radial direction", "circumferential direction", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of explaining the present application and simplifying the description, and do not mean or imply that the devices or elements mentioned must have a specific orientation and must be configured and operated in a specific orientation, and should not be construed as limiting the present application.

[0019] It should be noted that the terms "first" and "second" are for illustrative purposes only and are not understood to imply or suggest relative importance or to indicate the number of technical features described. Therefore, the features limited by "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, unless otherwise explicitly and specifically limited, the meaning of "a plurality" is at least two, for example, two, three, etc.

For example, it may be a fixed connection, a detachable connection, or an integrated one. Also, it may be mechanically connected or electrically connected.

[0023] The cable connection device is widely applied to various power supply devices and realizes the transmission of current or signals through cable connection.

[0024] In the prior art, the commonly used cable connection methods include non-removable methods and removable methods. The non-removable method includes welding. Since welding needs to be completed in the factory and transported to the site for work, such a connection method is inconvenient for maintenance and repair, and the cost is high. That is, the convenience of the welding connection method is poor. The removable method includes bolt locking. The connection method of bolt locking requires the use of tools to lock or unlock, and has high requirements for the locking moment. If the locking moment is insufficient, poor contact is likely to occur. If the locking moment is too large, the bolt is prone to wear, and the contact resistance becomes large after long-term use, the temperature rise is too high, and eventually a burnout phenomenon occurs. That is, the reliability of the bolt locking connection method is poor.

[0025] Based on this, it is necessary to provide a cable connector to solve the problems of poor convenience and reliability of the cable connection method in the prior art.

[0026] Referring to FIGS. 1 and 2, FIG. 1 shows a structural schematic diagram when the rotating member according to an embodiment of the present application is in the first position, and FIG. 2 shows a structural schematic diagram when the rotating member according to an embodiment of the present application is in the second position. The cable connector provided by an embodiment of the present application includes a casing 100, a connection member 200, a wire pressing elastic member 300 and a rotating member 400.

[0027] The connection part 210 of the connection member 200 is provided inside the casing 100. The wire pressing elastic member 300 is located inside the casing 100. The wire pressing elastic member 300 has a pressing part. The pressing part and the connection part 210 are arranged to face each other. A clamp opening for inserting a cable is formed between the pressing part and the connection part 210. The rotating member 400 includes a handle and a cam structure 410. The cam structure 410 is connected to one end of the handle. The cam structure 410 is rotatably connected to the casing 100. The cam structure 410 abuts against the wire pressing elastic member 300. The rotating member 400 has a first position and a second position. When the rotating member 400 is in the first position, the clamp opening presents an open state, and the cross-sectional dimension of the clamp opening is larger than the cross-sectional dimension of the cable. When the rotating member 400 is in the second position, the clamp opening presents a pressed state, and the cross-sectional dimension of the clamp opening is smaller than the cross-sectional dimension of the cable. The connection part 210 and the pressing part are each used to abut against the outer surface of the cable.

[0028] Specifically, for the cable connector of this embodiment, when the rotating member 400 rotates, the cam structure 410 drives the pressing part to move relative to the connection part 210, thereby further realizing the insertion and pressing connection of the cable. In the actual use process, when the rotating member 400 is rotated to the first position, the cam structure 410 drives the pressing part of the wire pressing elastic member 300 to move away from the connection part 210 along with the rotation of the rotating member 400 based on the eccentric characteristics, and further gradually opens the clamping port, facilitating the insertion of the end of the cable. Then, when the rotating member 400 is rotated to the second position, the cam structure 410 drives the pressing part of the wire pressing elastic member 300 to move towards the side approaching the connection part 210, further gradually closes the clamping port, and realizes the return by the elastic force of the wire pressing elastic member, and the pressing part presses the end of the cable against the connection part 210 to complete the pressing connection of the cable. When it is necessary to remove the cable, if the rotating member 400 is rotated to the first position, the cable can be extracted. Compared with the cable connection method in the prior art, the present application can conveniently realize the connection and removal of the cable, and realizes the pressing of the cable by the elastic force method. Regardless of the locking moment in the bolt lock, the connection consistency is good, improving the connection reliability.

[0029] In addition, the rotating member 400 may be configured as a rotating wrench.

[0030] As shown in FIGS. 1 to 3, FIG. 3 shows a structural schematic diagram of the wire pressing elastic member according to an embodiment of the present application. In some embodiments, the wire pressing elastic member 300 shown in this embodiment includes an elastic body 310, a housing 320, and a sheet body 330. The elastic body 310 abuts against the cam structure 410. One end of the elastic body 310 is connected to the housing 320, and the other end of the elastic body 310 is connected to the sheet body 330. The sheet body 330 is located inside the housing 320. The connection part 210 is located inside the housing 320 and is connected to the sheet body 330. The pressing part is formed on the inner wall surface of the housing 320 on the side facing the connection part 210. Further, the elastic body 310, the housing 320, and the sheet body 330 are of an integral structure.

[0031] Specifically, due to the action of the elastic force of the elastic body 310, the sheet body 330 can abut against the inner wall surface of the housing 320. When the rotating member 400 rotates from the second position to the first position, the cam structure 410 presses the elastic body 310, thereby driving the housing 320 to move downward, gradually separating the inner wall surface of the housing 320 from the connection part 210, and further opening the clamp opening. After the cable is inserted into the clamp opening, the rotating member 400 is rotated from the first position to the second position, and the elastic force generated by the recovery of the deformation of the elastic body 310 drives the housing 320 to move upward until the inner wall surface of the housing 320 presses against the outer surface of the cable, thereby realizing pressing the cable against the connection part 210.

[0032] As shown in FIGS. 4 to 7, FIG. 4 shows a schematic diagram of the overall structure of a cable connector according to an embodiment of the present application, FIG. 5 shows a schematic diagram of an exploded structure of a cable connector according to an embodiment of the present application, FIG. 6 shows a schematic structural diagram of a first housing according to an embodiment of the present application, and FIG. 7 shows a schematic structural diagram of a second housing according to an embodiment of the present application. In some embodiments, the casing 100 of this embodiment includes a first housing 110 and a second housing 120, and the first housing 110 and the second housing 120 are removably connected.

[0033] Specifically, the assembly of the cable connector is realized by the joining of the first housing 110 and the second housing 120.

[0034] As shown in FIGS. 4 to 6, in some embodiments, the casing 100 of this embodiment is provided with a first receiving groove 111 that matches the rotating member 400. When the rotating member 400 is in the first position, the rotating member 400 is located outside the first receiving groove 111, and when the rotating member 400 is in the second position, the rotating member 400 is located inside the first receiving groove 111.

[0035] Specifically, by providing the first storage groove 111 in the casing 100, when the rotating member 400 is rotated to the second position to realize cable connection, the rotating member 400 can be stored in the first storage groove 111, and furthermore, the space occupied by the overall structure is reduced.

[0036] Also, the first storage groove 111 is located in the first housing 110.

[0037] As shown in FIGS. 6 and 8, FIG. 8 shows a schematic structural diagram of a rotating member according to an embodiment of the present application. In some embodiments, a lock portion 112 is provided on the casing 100 of this embodiment, and a concave groove 420 that matches the lock portion 112 is provided on the rotating member 400. When the rotating member 400 is located in the first storage groove 111, the lock portion 112 is connected to the concave groove 420.

[0038] Specifically, when the rotating member 400 is rotated to the second position to realize cable connection, the rotating member 400 is stored in the first storage groove 111, and the lock portion 112 is connected to the concave groove 420, thereby locking the rotating member 400 in the second position. Thereby, the problem that the rotating member 400 is easily disengaged under the elastic force of the wire pressing elastic member 300 is improved, and furthermore, the reliability of cable connection is improved.

[0039] Also, the concave groove 420 is located on the handle, and the lock portion 112 is located in the first housing 110.

[0040] As shown in FIGS. 4 to 7 and FIG. 9, FIG. 9 shows a schematic structural diagram of an observation window body according to an embodiment of the present application. In some embodiments, an observation window 130 facing the clamp opening is further provided on the casing 100 of this embodiment.

[0041] Specifically, the connection status of the cable inside the casing, for example, whether the cable is inserted into a predetermined position and whether the cable is pressed against the connection portion 210, can be observed through the observation window 130.

[0042] In addition, an observation window body 500 is provided within the observation window 130. The observation window body 500 has a transparent structure, and through the observation window body 500, the connection status of the cable can be observed. Protrusion structures 510 on both sides of the observation window body 500 engage the observation window body 500 within the observation window 130, thereby closing the observation window 130 and improving the sealing performance of the casing 100.

[0043] As shown in FIG. 6, in some embodiments, the casing 100 of this embodiment is further provided with a cable passing structure 113. When the clamp opening is in an open state, the cable passing structure 113 and the clamp opening are installed opposite to each other, and the cable passing structure 113 is used to guide the cable into the clamp opening.

[0044] Specifically, when the rotating member 400 rotates from the second position to the first position, the cam structure 410 presses the elastic body 310, driving the housing 320 to move downward. Until the clamp opening and the cable passing structure 113 are opposite to each other, the clamp opening gradually opens, whereby the cable is introduced into the clamp opening through the cable passing structure 113, and further the connection of the cable is completed.

[0045] In addition, the cable passing structure 113 has a cylindrical shape and is located in the first housing 110.

[0046] As shown in FIGS. 1, 2, and 10, FIG. 10 shows a structural schematic diagram of a connection member according to an embodiment of the present application. In some embodiments, the connection member 200 of this embodiment includes a connection body 220. A butting portion 230 is provided at the first end of the connection body 220, and the connection portion 210 is formed at the other end of the connection body 220.

[0047] Specifically, the butting portion 230 has an insertion and extraction type structure and is used for insertion with an electrical component. The tip 121 of the second housing 120 is used to cover the butting portion 230.

[0048] Furthermore, as shown in FIG. 10, in some embodiments, a tooth-shaped structure 211 is formed on the side facing the pressing portion of the connection portion 210 of this embodiment. The tooth-shaped structure 211 is used to increase the frictional force between the connection portion 210 and the cable, thereby improving the reliability of the cable connection.

[0050] Specifically, by providing a plurality of second storage grooves 122, connection with a plurality of cables can be realized. At the same time, the second storage grooves 122 can isolate each connection member 200, so that adjacent cables do not contact each other.

[0051] Also, the second storage groove 122 is located in the second housing 120. The second housing 120 is further provided with a rotating shaft groove 123 for connecting to the rotating shaft of the cam structure 410.
