Description

Technical Field

[0001] This utility model relates to the field of socket connector technology, and in particular to a clamp-type socket. Background Technology

[0002] With the rapid development of electrical technology and the widespread application of power facilities, the demand for sockets in modern life has transcended the simple function of power transmission, placing greater emphasis on safety, convenience, and durability. Traditional socket designs primarily consist of metal contacts fixed within a casing, used to form an electrical connection with appliance plugs. However, in practical applications, traditional sockets have revealed a series of problems that not only affect the user experience but may also pose safety hazards. These problems with traditional sockets include:

[0003] Poor plug stability: In order to improve the installation speed, the connection between traditional sockets and plugs mainly relies on physical friction, that is, the plug is fixed by snap-fit. However, this connection method lacks sufficient mechanical strength and locking mechanism, and is prone to loosening during use. Under external impact or long-term use, the plug is also prone to accidentally slipping out of the socket, which not only affects normal use, but also poses a risk of electric shock, affecting the safety and reliability of the socket.

[0004] Installation and maintenance are inconvenient: For high-current sockets, a copper busbar or cable needs to be connected to the rear end to achieve a stable connection with the power grid. Existing connection methods mostly use screw fastening, which provides a certain level of mechanical strength, but the installation process is complex and time-consuming. Furthermore, screw-fastened connections are prone to loosening due to vibration and other factors during long-term use, affecting the safe and stable operation of the circuit. Utility Model Content

[0005] This utility model aims to at least solve the technical problems existing in the prior art. To this end, this utility model proposes a clamp-type socket, which can conveniently and quickly complete the connection between the back end of the socket and the copper busbar or cable, and can also securely fix the plug at the front end, while ensuring the efficiency and reliability of the installation process.

[0006] A clamp-type socket includes a housing and a socket connector. The socket connector is rotatably disposed at the front end of the housing. A conductive element is disposed inside the socket connector. A socket hole is disposed at the front end of the conductive element. A rotation locking mechanism is disposed on the socket hole. A movable groove is disposed at the rear end of the housing. A threaded hole is disposed through the housing. The rear end of the conductive element passes through the threaded hole and is screwed to the threaded hole. A ratchet is disposed on the outer periphery of the socket connector. A latching element is movably disposed on the housing. The latching element is located on the outer periphery of the ratchet. A movable contact element is connected to the rear end of the conductive element. A fixed contact element is disposed at the end of the movable groove away from the conductive element. A piercing spring is disposed on the fixed contact element or the movable contact element.

[0007] A clamp-type socket according to some embodiments of the present utility model has at least the following beneficial effects:

[0008] This utility model features a rotating locking mechanism on the socket. After the plug is inserted, rotating it locks it in place, ensuring the plug won't easily fall out. This enhances the connection stability between the plug and socket, effectively preventing poor contact caused by a loose plug. The movable contact and the fixed contact fixed in the movable slot form a clamp-like shape. By rotating the external socket connector, the movable contact moves towards the fixed contact, piercing the insulation layer of the copper busbar or cable through a piercing spring. This ensures a good electrical connection between the conductive component and the fixed contact, avoiding safety hazards such as overheating and arcing caused by poor contact. Since the plug also needs to rotate within the rotating locking mechanism, its rotation easily drives the conductive component to rotate as well. This can cause the movable contact to shift, opening the jaws and causing the rear end of the conductive component to detach from the copper busbar or cable. Therefore, this invention incorporates a ratchet and a locking mechanism. When the locking mechanism works in conjunction with the ratchet, the socket connector can only rotate in one direction, meaning the movable contact can only move towards the fixed contact. At this point, regardless of how the plug rotates within the rotating locking mechanism, the rear end of the conductive component will not detach from the copper busbar or cable. When the locking mechanism retracts and no longer interferes with the ratchet, the socket connector can rotate freely, allowing the jaws to loosen the copper busbar or cable, greatly improving safety and simplifying operation. This socket is convenient for connecting the front socket to the plug or the rear jaws to the copper busbar or cable, significantly enhancing connection stability and safety during use.

[0027] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, left, right, front, and back, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] like Figures 1-6 As shown, this utility model embodiment provides a clamp-type socket.

[0032] This example provides a clamp-type socket, including a housing 1 and a socket connector 2. The socket connector 2 is rotatably disposed at the front end of the housing 1. A conductive element 3 is disposed inside the socket connector 2. A socket hole 4 is disposed at the front end of the conductive element 3. A rotation locking mechanism 5 is disposed on the socket hole 4. A movable groove 6 is disposed at the rear end of the housing 1. A screw hole 7 is disposed through the housing 1. The rear end of the conductive element 3 passes through the screw hole 7 and is screwed to the screw hole 7. A ratchet 8 is disposed on the outer periphery of the socket connector 2. A latching element 9 is movably disposed on the housing 1. The latching element 9 is located on the outer periphery of the ratchet 8. A movable contact 10 is connected to the rear end of the conductive element 3. A fixed contact 11 is disposed at the end of the movable groove 6 away from the conductive element 3. A piercing spring 12 is disposed on the fixed contact 11.

[0033] This utility model features a rotating locking mechanism 5 on the socket 4. After the plug is inserted, rotating it locks the connection, ensuring the plug won't easily fall out. This enhances the connection stability between the plug and socket, effectively preventing poor contact caused by a loose plug. The movable contact 10 and the fixed contact 11, fixed in the movable slot 6, form a clamp-like shape. By rotating the external socket connector 2, the movable contact 10 can move towards the fixed contact 11, thereby piercing the insulation layer of the copper busbar or cable through the piercing spring 12. This ensures a good electrical connection between the conductive component 3 and the fixed contact 11, avoiding safety hazards such as overheating and arc discharge caused by poor contact. Since the plug also needs to rotate within the rotating locking mechanism 5, its rotation easily drives the conductive component 3 to rotate as well. This causes the movable contact 10 to shift, opening the jaws and causing the rear end of the conductive element 3 to detach from the copper busbar or cable. Therefore, this utility model is equipped with a ratchet 8 and a latching element 9. When the latching element 9 works with the ratchet 8, the socket connector 2 can only rotate in one direction, that is, the movable contact 10 can only move towards the fixed contact 11. At this time, no matter how the plug rotates in the rotation locking mechanism 5, the rear end of the conductive element 3 will not detach from the copper busbar or cable. When the latching element 9 is released and no longer interferes with the ratchet 8, the socket connector 2 can rotate freely. At this time, the jaws can loosen the copper busbar or cable, which greatly improves safety and is easy to operate. This socket is very convenient for connecting the front socket 4 to the plug or the rear jaws to the copper busbar or cable, and at the same time greatly improves the connection stability and safety during use.

[0034] According to some embodiments of the present invention, a clamp-type socket is provided with a positioning groove 13 on the outer wall of the housing 1. A rotating shaft 14 is provided in the middle of the positioning groove 13. A rotating hole 15 is provided in the middle of the buckle 9. The rotating shaft 14 passes through the rotating hole 15. A pressing part 16 and a snap-fit ​​part 17 are respectively provided on both sides of the rotating hole 15. A positioning hole 18 is provided through the bottom of one end of the positioning groove 13. The snap-fit ​​part 17 is correspondingly provided with the positioning hole 18. A first snap block 19 is provided at the bottom of the snap-fit ​​part 17. The first snap block 19 is correspondingly provided with the ratchet 8. A first guide slope 20 is provided at the end of the first snap block 19 near the rotating hole 15. A first abutting plane 21 is provided at the end of the first snap block 19 away from the rotating hole 15. Specifically, by setting the rotating shaft 14, the latching member 9 can rotate, and the latching part 17 can extend into the ratchet 8 through the positioning hole 18 to work with the ratchet 8. The first latching block 19 is engaged with the tooth groove of the ratchet 8, so that the socket connector 2 cannot be reversed. When the pressing part 16 is pressed down, the latching part 17 is lifted, so that the first latching block 19 extends out from the tooth groove of the ratchet 8. At this time, the socket connector 2 can be rotated in the opposite direction. The above structure is easy to operate. The socket connector 2 can be rotated in the opposite direction and the jaws can be released simply by pressing the pressing part 16.

[0035] According to some embodiments of the present invention, a clamp-type socket is provided at the bottom of the latching part 17, the second latching block 22 is located at the end of the first latching block 19 near the rotating hole 15, the end of the second latching block 22 near the rotating hole 15 is provided with a second guide slope 23, the end of the second latching block 22 away from the rotating hole 15 is provided with a second abutting plane 24, and the radial length of the second latching block 22 is less than the radial length of the first latching block 19. Specifically, the second locking block 22 can better prevent the socket connector 2 from rotating. It is understood that since the radius of rotation of the locking part 17 along the rotating shaft 14 is smaller than the radius of rotation of the socket connector 2, if the cross-section of the second locking block 22 is the same as the cross-section of the ratchet 8 tooth groove, the second locking block 22 will have difficulty completely exiting from the ratchet 8 tooth groove, which may easily lead to jamming. By setting the radial length of the second locking block 22 to be smaller than the radial length of the first locking block 19, the second locking block 22 is located at a shallower depth in the ratchet 8 tooth groove, making it easier to exit and preventing jamming. The above structural setting can improve the stability of the ratchet 8 and the locking part 17 working together.

[0036] It is understood that the axial and radial directions in this invention refer to the axial and radial directions of the insertion hole 4.

[0037] A jaw-type socket according to some embodiments of the present invention, an assembly hole 25 is formed at the bottom of the positioning groove 13, a spring (not shown) is arranged in the assembly hole 25, and the top of the spring is connected to the bottom of the pressing part 16. Specifically, when the ratchet 8 rotates and the clamping part 17 slides into the next tooth groove of the ratchet 8, affected by the restoring force of the spring 26, the clamping part 17 can quickly press down, and the first clamping block 19 and the second clamping block 22 quickly extend into the tooth groove of the ratchet 8. Similarly, when the pressing part 16 is unlocked by pressing, when the pressing part 16 is released, the clamping part 17 can also quickly press down, and the first clamping block 19 and the second clamping block 22 also quickly extend into the tooth groove of the ratchet 8, improving safety.

[0038] It can be understood that a threaded section 26 is provided at the rear end of the conductive part, and the threaded section 26 is screwed with the screw hole 7.

[0039] A jaw-type socket according to some embodiments of the present invention, when the movable contact 10 is located at the end closest to the screw hole 7, the distance from the puncture elastic piece 12 is L1; the length of the tooth groove of the ratchet 8 in the axial direction is L2; the length of the first clamping block 19 in the axial direction is L3, then the following relationship is satisfied among L1, L2 and L3: L1 < L2 + L3. To ensure that at any position of the movable contact 10 in the movable groove 6, the first clamping block 19 can interfere with the ratchet 8 and cooperate with the ratchet 8 to work.

[0040] It can be understood that a clearance space 27 is provided between the rear end of the first clamping block 19 and the housing 1 in the axial direction, so that when the socket connector 2 rotates and displaces towards the movable groove 6, the ratchet 8 can extend into the clearance space 27. Let the length of the clearance space 27 in the axial direction be L4, then the following relationship is satisfied among L1, L3 and L4: L1 < L3 + L4. Satisfying the above formula ensures that the clearance space 27 covers the movement range of the ratchet 8 in the axial direction.

[0041] A jaw-type socket according to some embodiments of the present invention, the rotation locking mechanism 5 includes a rotation groove 28, a guiding groove 29 and a locking hole 30. The rotation groove 28 is annularly arranged on the inner wall of the jack 4. Both ends of the guiding groove 29 are respectively communicated with the rotation groove 28 and the outer side of the conductive part 3. The locking hole 30 is arranged on the inner wall of the rotation groove 28 far from the movable groove 6. Both ends of the locking hole 30 in the radial direction penetrate through the jack 4 and the outer side of the conductive part 3 respectively. Specifically, two guiding grooves 29 and two locking holes 30 are provided. A locking block is provided in cooperation with an external plug. The locking block extends along the guiding groove 29 and then rotates along the rotation groove 28 to the locking hole 30. When the locking block extends into the locking hole 30, locking is achieved. When the plug needs to be withdrawn, the locking block slides out of the locking hole 30 into the rotation groove 28, and then rotates along the rotation groove 28 to the guiding groove 29 and extends out along the guiding groove 29 to achieve unlocking.

[0042] It is understandable that, in addition to the structure described above, there are many other rotation locking methods for sockets and plugs in the prior art, which will not be elaborated here.

[0043] According to some embodiments of this utility model, a clamp-type socket includes a first positioning hole 31 on the movable contact 10 and a second positioning hole 32 at the rear end of the conductive member 3. A floating screw 33 is disposed between the first positioning hole 31 and the second positioning hole 32. A limiting block 34 protrudes from the top of the movable contact 10, and a limiting groove 35 is formed on the inner wall of the top of the movable groove 6. The limiting block 34 extends into the limiting groove 35. Specifically, the movable contact 10 is connected to the conductive member 3 by the floating screw 33, and the movable contact 10 can move within a certain range by rotating the conductive member 3 through the cooperation of the limiting block 34 and the limiting groove 35, while maintaining a stable position and preventing rotation.

[0044] In this embodiment, a clamp-type socket is provided, with slots 36 at both the upper and lower ends of the fixed contact 11, and locking blocks 37 at both the upper and lower ends of the piercing spring 12. The locking blocks 37 engage with the slots 36. Specifically, the piercing spring 12 engages with the slots 36 on the fixed contact 11 via the locking blocks 37, simplifying the installation process of the piercing spring 12 and ensuring its stability during use. This design helps improve the overall stability and durability of the socket.

[0045] It is understandable that the piercing shrapnel 12 could also be placed on the movable contact 10, with the same effect.

[0046] In this embodiment, a clamp-type socket is provided with an insulating sleeve 38 at the front end of the conductive component 3. Specifically, the insulating sleeve 38 at the front end of the conductive component 3 can effectively prevent accidental contact and increase the safety of use.

[0047] In this embodiment, a clamp-type socket is provided with a central shaft 39 in the middle of the socket 4, and an insulating cap 40 is provided at the front end of the central shaft 39. Specifically, the insulating cap 40 at the front end of the central shaft 39 can provide a certain degree of insulation, thereby increasing the safety performance of the socket.

[0048] In this embodiment, a clamp-type socket is provided with finger-proof baffles 41 on the outer periphery of both the fixed contact 11 and the movable contact 10. Specifically, the finger-proof baffles 41 effectively prevent users from accidentally touching live parts, increasing the socket's safety. This is especially important for families with children or pets, as it effectively reduces the risk of accidental electric shock.

[0049] It is understood that the conductive component 3 has an annular groove 42 on its outer periphery, and the inner wall of the socket connector 2 has a protrusion 43 that extends into the annular groove 42 to achieve axial positioning. The conductive component 3 has limiting planes 44 on both sides, and the socket connector 2 abuts against the limiting planes 44 so that when the socket connector 2 rotates, it drives the conductive component 3 to rotate synchronously.

[0050] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
