[0018] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, unless there is a conflict, the embodiments of the present disclosure and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Example of copper terminal access socket:

[0020] See also Figure 1 , Figure 1 A schematic diagram of the structure of the copper terminal access socket provided by an embodiment of the present invention. As shown in the figure, the copper terminal access socket includes: an insulating shell 1, a pressing device 2 and a locking device 3. Among them, the interior of the insulating shell 1 is hollow, and one end of the insulating shell 1 ( Figure 1 The right end shown) is the open end, and the other end ( Figure 1 The open end of the insulating housing 1 is used to insert the copper terminal 4 connected to the cable 5. Specifically, the first end of the copper terminal 4 ( Figure 1 The right end shown) is connected to the cable 5, and the second end of the copper terminal 4 ( Figure 1 The left end shown in the figure) is inserted into the interior of the insulating housing 1 from the open end of the insulating housing 1.

[0021] Part of the pressing device 2 is placed inside the insulating housing 1 , and part of the pressing device 2 is placed outside the insulating housing 1 . The part of the pressing device 2 placed inside the insulating housing 1 is used to press the first end of the copper terminal 4 .

[0022] The portion of the clamping device 2 located outside the insulating housing 1 can be connected to another mounting device to enable access to the cable 5. In a specific implementation, the mounting device is a device that requires access to the cable 5, such as a switch cabinet. In this embodiment, the copper terminal access socket is connected to the switch cabinet and can be connected to the copper terminal 4 containing the cable 5. This allows the copper terminal 4 to be quickly connected to the switch cabinet. Specifically, the portion of the clamping device 2 located outside the insulating housing 1 is used to connect to the busbar of the switch cabinet.

[0023] The locking device 3 is arranged inside the insulating housing 1 , and is used to lock the copper terminal 4 .

[0024] It can be seen that in this embodiment, the copper terminal 4 installed with the cable 5 is inserted into the inside of the insulating shell 1, the clamping device 2 presses the copper terminal 4, and the locking device 3 locks the copper terminal 4. The copper terminal 4 is fixed by the joint action of the clamping device 2 and the locking device 3, thereby ensuring the stable insertion of the copper terminal 4 and preventing the copper terminal 4 from detaching from the insulating shell 1. When in use, it is only necessary to insert the copper terminal 4 installed with the cable 5 into the insulating shell 1 to achieve quick access to the copper terminal 4 installed with the cable 5. This is simple and convenient, easy to install, saves time, improves work efficiency, and solves the problem in the prior art that low-voltage coaxial cables installed with ordinary copper terminals cannot be quickly accessed.

[0025] In the above embodiment, the copper terminal access socket may further include a temperature detection device. The temperature detection device is disposed on the outer wall of the insulating housing 1 and is used to detect the temperature of the insulating housing 1, thereby enabling real-time temperature monitoring of the insulating housing 1. Preferably, the temperature detection device is a temperature-sensitive material disposed on the outer wall of the insulating housing 1. The temperature-sensitive material may be a thermochromic rubber material, thereby enabling real-time temperature indication.

[0026] When the copper terminal 4 is connected to the socket and the switch cabinet, the copper terminal 4, the busbar and the clamping device 2 may have poor contact or excessive operating load, causing the parts at the interface to heat up. The temperature detection device can detect the temperature of the insulating shell 1 in real time, eliminating the need for staff to conduct regular inspections and temperature measurements, simplifying the complexity of the operation and reducing labor intensity.

[0027] See also Figure 1 and Figure 2In the above embodiment, the pressing device 2 may include: a conductive pressure plate 21, a conductive connecting plate 22 and at least one pressing mechanism 23. The conductive connecting plate 22 is provided through the closed end of the insulating shell 1, and part of the conductive connecting plate 22 is placed outside the insulating shell 1 and part of it is placed inside the insulating shell 1. Part of the conductive connecting plate 22 is placed outside the insulating shell 1. The part of the conductive connecting plate 22 placed inside the insulating shell 1 is connected to the inner wall of the insulating shell 1, and the conductive connecting plate 22 is provided along the length direction of the insulating shell 1 ( Figure 1 The left-to-right direction shown in FIG.

[0028] In this embodiment, the portion of the conductive connecting plate 22 disposed outside the insulating housing 1 is connected to the switch cabinet.

[0029] The conductive plate 21 is placed inside the insulating housing 1, and the conductive plate 21 is suspended. The conductive plate 21 and the conductive connecting plate 22 are arranged in parallel. The conductive plate 21 is placed above the conductive connecting plate 22 (relative to the conductive connecting plate 22). Figure 1 Specifically, the insulating shell 1 is in the shape of a rectangular parallelepiped, and has a certain length, with the open end and the closed end respectively located at two opposite ends in the length direction of the insulating shell 1, and the conductive connecting plate 22 is placed below the insulating shell 1 (relative to the inner wall of the insulating shell 1). Figure 1 The inner wall of the conductive plate 21 is connected to the insulating shell 1, and the conductive plate 21 is placed above (relative to Figure 1 There is a certain distance between the inner walls (in terms of the embodiment), and the distance can be determined according to actual conditions. This embodiment does not impose any limitation on this.

[0030] The gap between the conductive plate 21 and the conductive connecting plate 22 is used to clamp the copper terminal 4. Each clamping mechanism 23 is provided on the conductive plate 21. Preferably, the clamping mechanisms 23 are evenly distributed on the conductive plate 21. Each clamping mechanism 23 is used to maintain the gap between the conductive plate 21 and the conductive connecting plate 22 before inserting the copper terminal 4, and to apply force to the conductive plate 21 after inserting the copper terminal 4 to clamp the copper terminal 4.

[0031] In a specific implementation, there are three pressing mechanisms 23. Of course, the number of the pressing mechanisms 23 can be determined according to actual conditions, and this embodiment does not impose any limitation on this.

[0032] See also Figure 1Each clamping mechanism 23 may include a guide shaft 231, a spacer 232, a stopper plate 233, and a first elastic member 234. The spacer 232 is interposed between the conductive connection plate 22 and the conductive voltage plate 21, maintaining a certain gap between the conductive connection plate 22 and the conductive voltage plate 21. The thickness of the spacer 232 is less than the thickness of the copper terminal 4, meaning that the gap between the conductive connection plate 22 and the conductive voltage plate 21 is slightly less than the thickness of the first end of the copper terminal 4.

[0033] The first end of the guide shaft 231 ( Figure 1 The lower end shown in FIG) is connected to the inner wall of the insulating housing 1, and the guide shaft 231 is sequentially provided through the conductive connecting plate 22, the pad 232 and the conductive voltage plate 21. The second end of the guide shaft 231 ( Figure 1 Specifically, the first end of the guide shaft 231 is embedded in the insulating housing 1, and the guide shaft 231 is relatively fixed to the insulating housing 1. A through hole is opened on the conductive plate 21, and the guide shaft 231 is passed through the through hole of the conductive plate 21, so that the conductive plate 21 can move up and down (relative to the guide shaft 231) along the guide shaft 231. Figure 1 The second end of the guide shaft 231 is perpendicular to the limit plate 233, forming a "T" shape between the second end of the guide shaft 231 and the limit plate 233. The limit plate 233 limits the conductive plate 21, preventing it from separating from the guide shaft 231. There is a certain distance between the limit plate 233 and the upper inner wall of the insulating housing 1. This distance can be determined based on actual conditions and is not limited in this embodiment.

[0034] The first elastic member 234 is sleeved on the guide shaft 231 and is placed between the limit plate 233 and the conductive plate 21. The first elastic member 234 is used to squeeze the copper terminal 4 through the conductive plate 21. Preferably, the first elastic member 234 is a spring.

[0035] When in use, the copper terminal 4 is inserted between the conductive voltage plate 21 and the conductive connecting plate 22. Since the thickness of the pad 232 is less than the thickness of the copper terminal 4, the copper terminal 4 will squeeze the conductive voltage plate 21, causing the conductive voltage plate 21 to move upward (relative to the conductive voltage plate 21). Figure 1 Due to the obstruction of the limiting plate 233, the first elastic member 234 exerts a downward (relative to the conductive plate 21) elastic restoring force. Figure 1 The force of the conductive plate 21 causes the copper terminal 4 to be pressed downward, thereby compressing the copper terminal 4.

[0036] It can be seen that in this embodiment, after the copper terminal 4 is inserted between the conductive voltage plate 21 and the conductive connecting plate 22, the copper terminal 4 squeezes the conductive voltage plate 21 and then squeezes the first elastic member 234. The restoring force of the first elastic member 234 can squeeze the conductive voltage plate 21 and then compress the copper terminal 4. In this way, copper terminals 4 of various thicknesses can be compressed, the structure is simple, and it is easy to implement.

[0037] Preferably, the wall surface where the conductive plate 21 contacts the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6 to ensure the stability of electrical conduction between the conductive plate 21 and the copper terminal 4. The wall surface where the conductive connecting plate 22 contacts the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6 to ensure the stability between the conductive connecting plate 22 and the copper terminal 4.

[0038] Preferably, the wall surface of the conductive plate 21 in contact with the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6 ; and / or the wall surface of the conductive connection plate 22 in contact with the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6 .

[0039] When the wall surface where the conductive voltage plate 21 contacts the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6, and the wall surface where the conductive connecting plate 22 contacts the copper terminal 4 is provided with a plurality of conductive spring contact fingers 6, both sides of the copper terminal 4 are in contact with the conductive spring contact fingers 6, thereby ensuring good contact between the copper terminal 4 and the conductive connecting plate 22, thereby ensuring good contact between the copper terminal 4 and the switch cabinet, ensuring the conductive contact performance of both sides of the copper terminal 4, and improving the reliability of power supply.

[0040] See also Figure 1 In each of the above embodiments, the locking device 3 includes: a cover 31, a second elastic member 32, and a latch 33. The conductive plate 21 is provided with a through hole, and the cover 31 is detachably mounted at the through hole of the conductive plate 21. The cover 31 is recessed outwardly corresponding to the through hole to form an accommodating space. Specifically, the cover 31 is mounted on the through hole. The cover 31 is generally in the shape of a cap. The cover 31 is detachably connected to the conductive plate 21. The accommodating space is upward (relative to the insulating housing 1). Figure 1 (In terms of) extending at the inner wall.

[0041] The second elastic member 32 is disposed in the accommodating space. Preferably, the second elastic member 32 is a spring. The latch 33 is slidably disposed in the through hole. The first end ( Figure 1 The upper end shown in FIG) is connected to the second elastic member 32, and the second end of the latch 33 ( Figure 1The lower end of the latch 33 is shown in the figure and is locked in the through-hole of the copper terminal 4. Specifically, the latch 33 can slide up and down in the through-hole. The copper terminal 4 is inserted between the conductive voltage plate 21 and the conductive connection plate 22. The copper terminal 4 presses the second end of the latch 33, so that the first end of the latch 33 presses the second elastic member 32. Due to the blocking effect of the cap, the second elastic member 32 is compressed. The copper terminal 4 continues to be inserted. When the second end of the latch 33 contacts the through-hole of the copper terminal 4, the restoring force of the second elastic member 32 pushes the latch 33 to slide downward, so that the second end of the latch 33 is inserted into the through-hole of the copper terminal 4.

[0042] Preferably, the second end of the lock 33 is an inclined surface, and the end surface of the second end of the lock 33 is inclined toward the open end of the insulating housing 1, so that the end of the second end of the copper terminal 4 contacts the inclined surface of the second end of the lock 33, thereby gradually squeezing the lock 33.

[0043] It can be seen that in this embodiment, the locking device 3 has a simple structure, is easy to implement, and can achieve rapid locking of the copper terminal 4 and further rapid connection of the cable 5 .

[0044] See also Figure 1 In the above embodiment, the copper terminal access socket may further include an unlocking device 7. The insulating housing 1 has an opening corresponding to the locking device 3. The unlocking device 7 is disposed on the locking device 3 and corresponds to the opening. The unlocking device 7 is used to release the lock 33 from the copper terminal 4, allowing the copper terminal 4 to be separated from the insulating housing 1.

[0045] The unlocking device 7 may include: a pull rod 71, an unlocking pressure rod 72 and a support column 73. The first end of the pull rod 71 ( Figure 1 The lower end shown in FIG) is connected to the latch 33, the pull rod 71 is sequentially provided through the second elastic member 32 and the cover 31, and the second end of the pull rod 71 ( Figure 1 The upper end shown) and the first end of the unlocking pressure rod 72 ( Figure 1 The left end shown in FIG) is rotatably connected to unlock the second end of the pressure rod 72 ( Figure 1 The right end shown) is the free end.

[0046] Specifically, the unlocking lever 72 corresponds to the opening, the second elastic member 32 is sleeved on the pull rod 71 and placed between the first end of the latch 33 and the cover 31, and the second end of the pull rod 71 is placed outside the cover 31. The unlocking lever 72 can rotate relative to the pull rod 71. The second end of the unlocking lever 72 is the handheld end. The staff presses the second end of the unlocking lever 72 and pulls the pull rod 71 upward. The pull rod 71 drives the latch 33 to slide upward, so that the second end of the latch 33 is separated from the through hole of the copper terminal 4. At this time, the second elastic member 32 is in a compressed state, pulling the copper terminal 4 out from between the conductive voltage plate 21 and the conductive connection plate 22. The staff releases the unlocking lever 72, and the latch 33 slides downward under the action of the restoring force of the second elastic member 32 until the second elastic member 32 is in a natural state.

[0047] The insulating housing 1 has a through hole near the opening, into which a support post 73 is positioned. The support post 73 contacts both the cover 31 and the unlocking lever 72. When a worker presses the second end of the unlocking lever 72, the first end of the unlocking lever 72 tilts upward, using the support post 73 as a fulcrum. This in turn pulls the pull rod 71 upward, causing the latch 33 to slide upward.

[0048] It can be seen that in this embodiment, after the locking device 3 locks the through hole of the copper terminal 4, the unlocking device 7 unlocks the copper terminal 4, making it easy to remove the copper terminal 4 from the insulating housing 1. The structure is simple and easy to implement.

[0049] To sum up, in this embodiment, the copper terminal 4 installed with the cable 5 is inserted into the inside of the insulating shell 1, and the copper terminal 4 is fixed by the joint action of the clamping device 2 and the locking device 3, thereby ensuring the stable insertion of the copper terminal 4 and preventing the copper terminal 4 from being separated from the insulating shell 1. When in use, it is only necessary to insert the copper terminal 4 installed with the cable 5 into the insulating shell 1 to achieve quick access to the copper terminal 4 installed with the cable 5. It is simple and convenient, easy to install, saves time, and improves work efficiency.

The portion of the copper terminal access socket's clamping device 2 located outside the insulating housing 1 is connected to the busbar. Specifically, the portion of the conductive connecting plate 22 located outside the insulating housing 1 in the clamping device 2 is bolted to the busbar. The specific implementation of the copper terminal access socket can be found in the above description and will not be further elaborated in this embodiment.
