Description

Technical Field

[0001] This application relates to the field of electrical connection device technology, and in particular to a cable fixing device and a charging gun. Background Technology

[0002] The charging gun has terminals and a cable for power transmission. One end of the terminals is electrically connected to the cable. When the charging gun is used to charge the electrical device, the current is transmitted through the cable to the terminals and electrically connected to the corresponding terminals on the electrical device to charge the device.

[0003] In related technologies, the connection points of the cable and terminals in a charging gun require sealing protection. Therefore, the cable gun includes a cable fixing device, which comprises a device body and a fixing component for fixing the cable. The device body has a receiving channel to receive part of the cable and the connection point of the terminal, and a sealing component is provided between the receiving channel and the cable to ensure a sealed connection. Additionally, the fixing component is located at the end of the device body near the cable for securing the cable. During the use of the charging gun, the cable moves as it is removed, causing twisting and resulting in interaction forces between the cable, the device body, and the fixing component.

[0004] However, due to the weak fixing method of the fastener to the cable, the related technology has technical problems such as the cable easily coming out of the fixing range of the fastener when the cable is twisted, causing relative displacement in the charging gun and damaging the charging gun, as well as the relative displacement of the cable in the charging gun causing deformation of the seal and failure of the seal. Utility Model Content

[0005] This application provides a cable fixing device and a charging gun, which aims to solve the technical problems of charging gun damage and seal deformation caused by relative displacement of the cable in the charging gun, thereby avoiding cable displacement in the charging gun, reducing the damage rate of the charging gun, and improving the service life and charging reliability of the charging gun.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A first aspect of this application provides a cable fixing device suitable for a charging gun. The charging gun has at least two cable groups and at least two terminals. Each cable group has two cables, and two cables in each cable group are electrically connected to their corresponding terminals. The cable fixing device includes:

[0008] The device body has multiple first receiving channels. The connection ends of two cables and their corresponding terminals in each cable group are located in the corresponding first receiving channel and are sealed to the first receiving channel.

[0009] A fixing component is disposed at one end of the device body near the cable and connected to the device body. The fixing component has multiple second receiving channels, which are arranged one-to-one with multiple first receiving channels and extend in the same direction. Each second receiving channel has two sub-channels, and the two sub-channels and their corresponding two cables are arranged one-to-one.

[0010] In some embodiments, a plurality of the first accommodating channels are arranged sequentially along a first direction;

[0011] The fixing component includes a first fixing member and a second fixing member. The first fixing member has a first receiving groove arranged sequentially along a first direction, and the second fixing member has a second receiving groove arranged sequentially along the first direction. The first fixing member and the second fixing member are engaged with each other in a second direction so that the first receiving groove and the second receiving groove are arranged in a one-to-one correspondence. The first receiving groove and the corresponding second receiving groove together form the second receiving channel, and the first fixing member and the second fixing member are respectively connected to the device body.

[0012] In some embodiments, one of the first and second fasteners has a partition wall, and the other of the first and second fasteners has a groove that matches the partition wall. When the first and second fasteners are engaged, the partition wall is disposed within the groove to isolate two adjacent second receiving channels; or,

[0013] The first fastener has a first partition wall, and the second fastener has a second partition wall. When the first fastener and the second fastener are fastened together, the first partition wall and the corresponding second partition wall are in direct contact to jointly isolate two adjacent second accommodating channels.

[0014] In some embodiments, the cable fixing device further includes a third fixing member, which is at least partially located between the first fixing member and the second fixing member to isolate each of the second receiving channels into two sub-channels.

[0015] In some embodiments, the third fastener has a fixing bracket with a clearance space and an isolation structure extending in a first direction. When the first fastener and the second fastener are engaged, both the first fastener and the second fastener are at least partially located within the clearance space. The fixing bracket is connected to the first fastener and the second fastener respectively. The isolation structure is located between the first fastener and the second fastener to isolate each of the second accommodating channels into two sub-channels.

[0016] In some embodiments, the two ends of the fixing bracket are detachably connected to the first fixing member and the second fixing member, respectively.

[0017] In some embodiments, the first end of the fixing bracket has a first snap-fit ​​portion, the second end of the fixing bracket has a second snap-fit ​​portion, the first fixing member has a first snap-fit ​​position that matches the first snap-fit ​​portion, and the second fixing member has a second snap-fit ​​position that matches the second snap-fit ​​portion. When the fixing bracket is connected to the first fixing member and the second fixing member respectively, the first snap-fit ​​portion and the first snap-fit ​​position snap-fit ​​together, and the second snap-fit ​​portion and the second snap-fit ​​position snap-fit ​​together.

[0018] In some embodiments, along the direction from the second receiving channel to the first receiving channel, the first fixing member has a first extension, the second fixing member has a second extension, the first extension has a first limiting structure on the side facing the device body, and the second extension has a second limiting structure on the side facing the device body.

[0019] The device body has a circumferentially extending limiting portion at one end near the cable, and both the first limiting structure and the second limiting structure are matched with the limiting portion.

[0020] In some embodiments, the first limiting structure and the second limiting structure are one of a limiting protrusion and a limiting groove, and the limiting portion is the other of the limiting protrusion and the limiting groove.

[0021] In this embodiment, a fixing component is provided at one end of the device body near the cable. The second accommodating channel of the fixing component separates multiple cable groups and secures the outer periphery of each cable group from all directions, thus limiting the position of each cable group. This prevents relative displacement between cable groups within the charging gun when the cables twist. Furthermore, sub-channels are provided in the second accommodating channel to limit the position of each cable within each cable group, further preventing relative displacement between cables within each cable group when they twist. Therefore, by providing the fixing component in the cable fixing device, each cable will not shift relative to the fixing component and the device body within the charging gun when the cable twists, thereby reducing the damage rate of the charging gun and the risk of deformation of the seals, and ultimately improving the service life and charging reliability of the charging gun.

[0022] A second aspect of this application provides a charging gun, including a cable fixing device as described in any of the above-described embodiments.

[0023] The charging gun provided in this application embodiment has the same beneficial effects as the cable fixing device provided in the above embodiment, and will not be described again here.

[0024] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the cable fixing device and charging gun provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0046] 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. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] This application provides a charging gun that can be used to charge electric vehicles, electric ships, electric forklifts, emergency power vehicles, etc. The charging gun has at least two cable groups and at least two terminals. Each cable group has two cables, and the two cables in each cable group are electrically connected to their corresponding terminals. Furthermore, the charging gun includes a cable fixing device to secure the cables.

[0048] In some embodiments, the cable fixing device includes a device body and a fixing member for fixing the cable. The device body has a receiving channel to receive the connection ends of the cable and terminals in the cable assembly, and a seal is provided between the receiving channel and the cable to create a sealed connection. The fixing member is located at the end of the device body near the cable and connected to the device body for fixing cables between cable assemblies and between adjacent cables in the same cable assembly. Therefore, for cables in cable assemblies at the edge, the fixing member does not restrict the position between the cable and the environment outside the fixing member. Thus, during the use of the charging gun, when the cable twists due to positional movement, an interaction force is generated between the cable, the device body, and the fixing member. Under this force, the cable may detach from the fixing member, twisting or shifting relative to the device body, resulting in relative displacement within the charging gun. This displacement can damage the cable, the device body, or the fixing member, ultimately leading to damage to the charging gun. Additionally, the cable may exert force on the sealing member, causing deformation and seal failure.

[0049] To address the aforementioned technical problems, this application designs a cable fixing device to further improve upon the cable fixing device in the above embodiments. This cable fixing device is suitable for charging guns. The content of this application will now be described in detail with reference to the accompanying drawings to enable those skilled in the art to gain a clearer and more comprehensive understanding of its contents.

[0050] Figure 1 This is a schematic diagram of the structure of the device body provided in an embodiment of this application. Figure 2 This is a schematic diagram of a sealing element provided in an embodiment of this application. Figure 3This is a schematic diagram of a cable fixing device provided in an embodiment of this application. Figure 1 , Figure 2 and Figure 3 As shown, the cable fixing device 100 includes a device body 110 and a fixing component 120.

[0051] Among them, such as Figure 1 and Figure 2 As shown, the device body 110 has a plurality of first receiving channels 111, which are arranged sequentially along a first direction; the connection ends of the two cables 103 and their corresponding terminals 101 in each cable group 102 are located in their corresponding first receiving channels 111 and are sealed to the first receiving channels 111.

[0052] In some embodiments, the number of terminals 101, cable groups 102, and first receiving channels 111 in the charging gun is the same. For example, the number of terminals 101, cable groups 102, and first receiving channels 111 may be two, three, four, six, eight, ten, etc. In this embodiment, the example of two terminals 101, cable groups 102, and first receiving channels 111 in the charging gun will be used for illustration.

[0053] It should be noted that, as Figure 1 and Figure 2 As shown, the first direction is the arrangement direction of the multiple first receiving channels 111, and the second direction is the arrangement direction of the two cables 103 in the cable group 102. In order to facilitate a more regular arrangement of the cables 103, the arrangement direction of the first receiving channels 111 is defined as the horizontal direction, that is, the first direction is consistent with the horizontal direction. Therefore, the arrangement direction of the two cables 103 in the cable group 102 is the vertical direction, that is, the second direction is consistent with the vertical direction.

[0054] In addition, such as Figure 2 As shown, a first sealing element 104 is provided between the first receiving channel 111 and the terminal block 101, and the first sealing element 104 is disposed at one end of the first receiving channel 111 near the terminal block 101. A second sealing element 105 is provided between the first receiving channel 111 and each cable group 102, and the second sealing element 105 is disposed at one end of the first receiving channel 111 near the cable group 102. The arrangement of the first sealing element 104 and the second sealing element 105 makes the connection end of the first receiving channel 111 sealed with the two cables 103 in each cable group 102 and their corresponding terminal blocks 101, thereby sealing and protecting the connection end of each cable 103 and the terminal block 101 to prevent the ingress of moisture and dust, which would affect the electrical connection performance between them.

[0055] For example, the first seal 104 has a plurality of first openings, the number of which is the same as the number of terminals 101, so that each terminal 101 passes through the corresponding first opening on the first seal 104 and is sealed to the first receiving channel 111 through the first seal 104; the second seal 105 has a plurality of second openings, the number of which is the same as the total number of cables 103 in all cable groups 102, so that each cable 103 passes through the corresponding second opening on the second seal 105 and is sealed to the first receiving channel 111 through the second seal 105.

[0056] In another example, both the first seal 104 and the second seal 105 are elastic elements, and the materials can be silicone rubber, nitrile rubber, fluororubber, neoprene rubber, etc.

[0057] Combination Figure 3 and Figure 4 As shown, the fixing component 120 in the cable fixing device 100 is disposed at one end of the device body 110 near the cable 103 and is connected to the device body 110. The fixing component 120 has a plurality of second receiving channels (not shown in the figure). The plurality of second receiving channels are arranged one-to-one with the plurality of first receiving channels 111 and extend in the same direction to limit each cable group 102. Each second receiving channel has two sub-channels, and the two sub-channels and their corresponding two cables 103 are arranged one-to-one to limit each cable 103 in each cable group 102.

[0058] For example, in the cable fixing device 100, both the device body 110 and the fixing component 120 are plastic parts, and the material can be polycarbonate, polyamide, polyphenylene ether, acrylonitrile-butadiene-styrene copolymer, etc.

[0059] In this embodiment, by providing a fixing component 120 at one end of the device body 110 near the cable 103, the second receiving channel of the fixing component 120 separates multiple cable groups 102 and fixes the outer periphery of each cable group 102 in all directions, thereby limiting the position of each cable group 102. This prevents relative displacement between each cable group 102 and the fixing component 120 in the charging gun when the cable 103 twists. In addition, by providing a sub-channel in the second receiving channel, the position of each cable 103 in each cable group 103 is further limited, thereby preventing relative displacement between each cable 103 in each cable group 102 and the fixing component 120 when the cable 103 twists. Therefore, by setting the fixing component 120 in the cable fixing device 100, when the cable 103 is twisted, each cable 103 will not be displaced relative to the fixing component 120 and the device body 110 in the charging gun, thereby reducing the damage rate of the charging gun and the risk of deformation of the seal, and thus improving the service life and charging reliability of the charging gun.

[0060] Furthermore, such as Figure 5 , Figure 6 and Figure 7 As shown, the fixing component 120 includes a first fixing member 121 and a second fixing member 122. The first fixing member 121 has a first receiving groove 1211 arranged sequentially along a first direction, and the second fixing member 122 has a second receiving groove 1221 arranged sequentially along the first direction. The first fixing member 121 and the second fixing member 122 are engaged with each other in a second direction so that the first receiving groove 1211 and the second receiving groove 1221 are arranged in a one-to-one correspondence. The first receiving groove 1211 and the corresponding second receiving groove 1221 together form a second receiving channel, and the first fixing member 121 and the second fixing member 122 are respectively connected to the device body 110.

[0061] The first fixing member 121 and the second fixing member 122 are configured in two ways. First, the multiple second receiving channels formed by the first fixing member 121 and the second fixing member 122 can fix the outer periphery of the corresponding multiple cable groups 102 in all directions, so that the cable group 102 will not be displaced relative to the second receiving channel when the cable 103 twists. Moreover, part of the second sealing member 105 is located between the second receiving channel and the cable 103. Therefore, the first fixing member 121 and the second fixing member 122 can provide a covering protection for the second sealing member 105 on the outer periphery of the cable group 102. Second, the first fixing member 121 and the second fixing member 122 make it more convenient to fit each cable group 102 into the corresponding second receiving channel. The first fixing member 121 and the second fixing member 122 can be fastened together, which is simple and easy to implement.

[0062] In some embodiments, along the circumferential direction of the first fixing member 121, both ends of the first fixing member 121 have fastening positions 1215, and along the circumferential direction of the second fixing member 122, both ends of the second fixing member 122 have fastening portions 1223. When it is necessary to fasten the first fixing member 121 and the second fixing member 122, the fastening positions 1215 at both ends of the first fixing member 121 and the fastening portions 1223 at both ends of the second fixing member 122 can be fastened accordingly. For example, the fastening position 1215 is one of a slot and a hook, and the fastening portion 1223 is the other of a slot and a hook. Specifically, in conjunction with... Figure 5 and Figure 6 As shown, the first fixing member 121 has protrusions at both ends, forming grooves around the protrusions, thus forming engagement positions 1215 at both ends of the first fixing member 121. The engagement portions 1223 at both ends of the second fixing member 122 are hooks extending from both ends of the second fixing member 122, and the shape of the hooks matches the shape of the grooves. During the mutual engagement of the first fixing member 121 and the second fixing member 122, under the action of the first fixing member 121 and the second fixing member 122, the hooks first deform and move relative to the protrusions, and then engage with the grooves, thereby completing the engagement connection between the first fixing member 121 and the second fixing member 122. The engagement connection of the first fixing member 121 and the second fixing member 122 is quick and simple to operate, has a robust structure, and high stability.

[0063] Furthermore, such as Figure 5 and Figure 6 As shown, along the direction from the second accommodating channel to the first accommodating channel 111, the first fixing member 121 has a first extension 1214, and the second fixing member 122 has a second extension 1222. The first extension 1214 has a first limiting structure on the side facing the device body 110, and the second extension 1222 has a second limiting structure on the side facing the device body 110. The device body 110 has a limiting portion extending circumferentially at the end near the cable 103. The first limiting structure and the second limiting structure are matched with the limiting portion, so that the first fixing member 121 and the second fixing member 122 are fixedly connected to the device body 110 while being fastened to each other. This enhances the connection strength between the device body 110 and the first fixing member 121 and the second fixing member 122, so that the force of the cable 103 on the cable fixing device 100 can be distributed to the device body 110, the first fixing member 121 and the second fixing member 122, and jointly borne by them, thereby improving the fixing reliability of the cable fixing device 100 on the cable 103.

[0064] For example, the first limiting structure and the second limiting structure are one of a limiting protrusion and a limiting groove, and the limiting part is the other of a limiting protrusion and a limiting groove. Of course, if the limiting part is a limiting protrusion, the limiting protrusion can be an annular limiting protrusion extending circumferentially along the outer periphery of the device body 110, and if the limiting part is a limiting groove, the limiting groove can be an annular limiting groove extending circumferentially along the outer periphery of the device body 110.

[0065] Additionally, in some embodiments, combined with Figure 6 and Figure 7 As shown, one of the first fixing member 121 and the second fixing member 122 has a partition wall 1212, and the other of the first fixing member 121 and the second fixing member 122 has a groove that matches the partition wall 1212. When the first fixing member 121 and the second fixing member 122 are engaged, the partition wall 1212 is disposed in the groove to isolate two adjacent second receiving channels. The partition wall 1212 allows adjacent cable groups 102 to be separated and fixed after the first fixing member 121 and the second fixing member 122 are engaged. The structure is simple and easy to manufacture.

[0066] For example, the number of second receiving channels formed by the partition wall 1212 is the same as the number of first receiving channels 111, but the number of partition walls 1212 is one less than the number of second receiving channels. The number of partition walls 1212 can be one, two, three, five, seven, nine, etc.

[0067] When the first fixing member 121 has a partition wall 1212, the end of the partition wall 1212 near the second fixing member 122 has a first connecting part, the second fixing member 122 has a groove, and the groove has a first connecting position at the corresponding position. The first connecting part and the first connecting position match each other. For example, the first connecting part is one of a protrusion and a groove, and the first connecting position is the other of a protrusion and a groove. When the first fixing member 121 and the second fixing member 122 are fastened together, the first connecting part and the first connecting position are engaged, thereby further increasing the connection strength between the first fixing member 121 and the second fixing member 122, so as to better resist the force exerted on the first fixing member 121 and the second fixing member 122 during the twisting of the cable 103, and avoid displacement of each cable group 102 relative to the corresponding second receiving channel, thereby improving the fixing reliability of the first fixing member 121 and the second fixing member 122 on each cable group 102.

[0068] When the second fixing member 122 has a partition wall 1212, the end of the partition wall 1212 near the first fixing member 121 has a first connecting part, the first fixing member 121 has a groove, and the groove has a first connecting position at the corresponding position. The first connecting part and the first connecting position match each other, which can further increase the connection strength between the first fixing member 121 and the second fixing member 122 and improve the fixing reliability of the first fixing member 121 and the second fixing member 122 for each cable group 102.

[0069] In other embodiments, the first fixing member 121 has a first partition wall and the second fixing member 122 has a second partition wall. When the first fixing member 121 and the second fixing member 122 are fastened together, the first partition wall and the corresponding second partition wall are in direct contact to jointly isolate two adjacent second accommodating channels, so as to separate and fix the adjacent cable groups 102. The structure is simple and easy to manufacture.

[0070] For example, the first partition wall has a first connecting portion at the end near the second fixing member 122, and the second partition wall has a first connecting position at the end near the first fixing member 121. The first connecting portion and the first connecting position are matched. Furthermore, one of them is a slot and the other is a protrusion. When the first fixing member 121 and the second fixing member 122 are fastened together, they are engaged, thereby further increasing the connection strength between the first fixing member 121 and the second fixing member 122 and improving the fixing reliability of the first fixing member 121 and the second fixing member 122 for each cable group 102.

[0071] In addition, combined Figure 3 and Figure 8 As shown, the cable fixing device 100 also includes a third fixing member 123, which is at least partially located between the first fixing member 121 and the second fixing member 122 to isolate each second receiving channel into two sub-channels. This allows the two cables 103 in each cable group 102 to be located in the corresponding sub-channels. Each cable 103 in each cable group 102 is fixed through the channel of the sub-channel, thereby preventing relative displacement between the cable 103 and the fixing component 120 when the cable 103 twists, and improving the fixing reliability of the fixing component 120.

[0072] It should be noted that, as Figure 7 As shown, along the second direction, after the first fixing member 121 and the second fixing member 122 are fastened together, there is a gap between the ends of the two that are away from the device body 110. This gap is used for the insertion of at least part of the third fixing member 123, thereby facilitating the installation and removal of the third fixing member 123.

[0073] For example, the third fixing member 123 can be a shaft-shaped member, a plate-shaped member, a block-shaped member, etc.; and the number of the third fixing members 123 can be multiple. Since there are two directions in which the third fixing member 123 is inserted into the gap between the first fixing member 121 and the second fixing member 122, the number of the third fixing member 123 is set to two. These two third fixing members 123 are respectively inserted into the gap from both sides along the first direction.

[0074] In some specific embodiments, such as Figure 8 As shown, the third fixing member 123 has a fixing bracket 1231, the fixing bracket 1231 has a clearance space 1232, and the clearance space 1232 has an isolation structure 1233 extending along the first direction. When the first fixing member 121 and the second fixing member 122 are fastened together, the first fixing member 121 and the second fixing member 122 are at least partially located in the clearance space 1232. The fixing bracket 1231 is connected to the first fixing member 121 and the second fixing member 122 respectively. The isolation structure 1233 is located between the first fixing member 121 and the second fixing member 122 to isolate each second accommodating channel into two sub-channels.

[0075] When the isolation structure 1233 in the third fixing member 123 is located between the first fixing member 121 and the second fixing member 122, the two ends of the fixing bracket 1231 are respectively connected to the first fixing member 121 and the second fixing member 122. By combining the first fixing member 121 and the second fixing member 122 through the fastening connection of the fastening position 1215 and the fastening part 1223, and the setting of the third fixing member 123, the second accommodating channel can be isolated to form two sub-channels, while increasing the connection points between the first fixing member 121 and the second fixing member 122. This further strengthens the connection strength between the first fixing member 121 and the second fixing member 122, and further strengthens the fixing strength of the fixing component 120 for each cable 103 in each cable group 102. This allows the fixing component 120 to lock each cable 103 in all directions along the outer periphery of each cable 103, preventing displacement of the cable group 102 relative to the fixing component 120 and the device body 110, and preventing the cable 103 from twisting and moving in the fixing component 120. This reduces the damage rate of the charging gun that uses the cable fixing device 100 to fix the cable 103, and reduces the failure risk of the first seal 104 and the second seal 105, ultimately improving the service life and charging reliability of the charging gun.

[0076] Furthermore, the two ends of the fixed bracket 1231 are detachably connected to the first fixing member 121 and the second fixing member 122, respectively, so as to facilitate the installation and removal of the third fixing member 123.

[0077] To achieve a detachable connection between the two ends of the fixed bracket 1231 and the first fixing member 121 and the second fixing member 122, as follows: Figure 8 As shown, the first end 1234 of the fixing bracket 1231 has a first snap-fit ​​portion 1235, and the second end 1236 of the fixing bracket 1231 has a second snap-fit ​​portion 1237. The first fixing member 121 has a first snap-fit ​​position 1213 that matches the first snap-fit ​​portion 1235, and the second fixing member 122 has a second snap-fit ​​position (not shown in the figure) that matches the second snap-fit ​​portion 1237. When the fixing bracket 1231 is connected to the first fixing member 121 and the second fixing member 122 respectively, the first snap-fit ​​portion 1235 and the first snap-fit ​​position 1213 snap-fit ​​together, and the second snap-fit ​​portion 1237 and the second snap-fit ​​position snap-fit ​​together. The two ends of the fixing bracket 1231 are connected to the first fixing member 121 and the second fixing member 122 respectively by a snap-fit ​​detachable connection method, which is simple in structure and convenient in operation.

[0078] For example, the first latching portion 1235 and the second latching portion 1237 are one of a latching protrusion and a latching groove, and the first latching position 1213 and the second latching position are the other of a latching protrusion and a latching groove. When the first latching position 1213 and the second latching position are latching protrusions, the first latching portion 1235 and the second latching portion 1237 can also be in the form of a latching hole.

[0079] like Figure 8 As shown, by combining the snap-fit ​​connection between the first fixing member 121 and the second fixing member 122 and the device body 110, the fastening connection between the first fixing member 121 and the second fixing member 122, and the snap-fit ​​connection between the third fixing member 123 and the first fixing member 121 and the second fixing member 122, the cable 103 located in the sub-channel is subjected to forces in all directions such as up, down, left, right, front, and back of the fixing component 120, so as to fix the cable 103 in all directions, thereby improving the stability of the cable 103 in the device body 110 and the fixing component 120, and improving the fixing reliability of the fixing component 120.

[0080] Furthermore, if the size of the cable 103 electrically connected to the terminal block 101 changes, only the sizes of the corresponding device body 110, first fixing member 121, second fixing member 122 and third fixing member 123 in the fixing assembly 120 need to be changed so that the sizes of the first receiving channel 111 and the second receiving channel are adapted to the size of the corresponding cable 103. There is no need to modify the structural design. Therefore, the cable fixing device 100 provided in this application also has the characteristic of high compatibility.

[0081] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic.
