Description

Technical Field

[0001] The invention relates to the technical field of socket connectors, in particular to a clamp-type socket. Background Art

[0002] With the rapid development of power technology and the widespread application of power facilities, the demand for sockets in modern life has gone beyond the simple power transmission function, and has turned to pay more attention to its safety, convenience and durability. The traditional socket design is mainly composed of metal contacts fixed in the shell, which are used to form an electrical connection with the electrical plug. However, in actual applications, traditional sockets have exposed a series of problems, which not only affect the user experience, but also may bring safety hazards. The problems of traditional sockets include:

[0003] Poor plug stability: In order to increase the installation speed, the connection between the traditional socket and the plug is mainly maintained by physical friction, that is, the plug is fixed by a snap-on method. However, this connection method lacks sufficient mechanical strength and locking mechanism, and is prone to loosening during use. It is also easy for the plug to accidentally slip out of the socket when subjected to external force or long-term use, which not only affects normal use, but also poses a risk of electric shock, affecting the safety and reliability of the socket.

[0004] Inconvenient installation and maintenance: For high-current sockets, the rear end needs to be connected to a copper bus or cable to achieve a stable connection with the power grid. The existing connection method mostly uses screws to fasten, which can provide a certain mechanical strength, but the installation process is complicated and time-consuming. In addition, the screw-fastened connection is prone to loosening due to factors such as vibration during long-term use, affecting the safe and stable operation of the circuit. Summary of the invention

[0005] The present invention aims to at least solve the technical problems existing in the prior art. To this end, the present invention proposes a clamp-type socket, which can conveniently and quickly complete the connection between the rear end of the socket and the copper bar or cable, and can firmly fix the plug at the front end, while ensuring the efficiency and reliability of the installation process.

[0006] A jaw-type socket comprises a shell and a socket connector, the socket connector can be rotatably arranged at the front end of the shell, a conductive piece is arranged inside the socket connector, a socket is arranged at the front end of the conductive piece, a rotation locking mechanism is arranged on the socket, a movable groove is arranged at the rear end of the shell, a screw hole is passed through the shell, the rear end of the conductive piece is penetrated through the screw hole, the rear end of the conductive piece is screwed with the screw hole, a ratchet is arranged at the outer periphery of the socket connector, a snap piece is movably arranged on the shell, the snap piece is located at the outer periphery of the ratchet, a movable contact piece is connected to the rear end end of the conductive piece, a fixed contact piece is arranged at the end of the movable groove away from the conductive piece, a puncturing spring sheet is arranged on the fixed contact piece or the movable contact piece, and a first clamping block is arranged at the bottom of the clamping piece, and the first clamping block is arranged corresponding to the ratchet.

When the snap member is withdrawn and no longer interferes with the ratchet, the socket connector can rotate freely. At this time, the jaws can loosen the copper bar or cable, which greatly improves safety and is convenient and quick to operate.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] like Figure 1-Figure 6 As shown, an embodiment of the present invention provides a clamp-type socket.

[0032] The present example provides a jaw-type socket, comprising a shell 1 and a socket connector 2, wherein the socket connector 2 is rotatably arranged at the front end of the shell 1, a conductive member 3 is arranged inside the socket connector 2, a socket 4 is arranged at the front end of the conductive member 3, a rotation locking mechanism 5 is arranged on the socket 4, a movable groove 6 is arranged at the rear end of the shell 1, a screw hole 7 is passed through the shell 1, the rear end of the conductive member 3 is penetrated through the screw hole 7, the rear end of the conductive member 3 is screwed to the screw hole 7, a ratchet 8 is arranged on the outer periphery of the socket connector 2, a snap-fit ​​member 9 is movably arranged on the shell 1, and the snap-fit ​​member 9 is located at the outer periphery of the ratchet 8, a movable contact member 10 is connected to the rear end end of the conductive member 3, a fixed contact member 11 is arranged at the end of the movable groove 6 away from the conductive member 3, and a piercing spring 12 is arranged on the fixed contact member 11.

[0033] The socket 4 of the present invention is provided with a rotary locking mechanism 5, which can be locked after the plug is inserted and rotated, ensuring that the plug will not fall off easily after being inserted, thereby enhancing the connection stability between the plug and the socket, and effectively preventing the poor contact problem caused by the loosening of the plug. The movable contact 10 and the fixed contact 11 fixed in the movable groove 6 form a jaw shape, and the movable contact 10 can be moved toward the fixed contact 11 by rotating the external socket connector 2, and then the insulating layer outside the copper bus or cable can be pierced by the piercing spring 12, ensuring a good electrical connection between the conductive member 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 in the rotary locking mechanism 5, it is easy to drive the conductive member 3 to rotate when the plug rotates, which will This causes the movable contact 10 to be displaced and the jaws to open, so that the rear end of the conductive member 3 falls off the copper bus or cable. Therefore, the present invention is provided with a ratchet 8 and a snap 9. When the snap 9 cooperates with the ratchet 8, the socket connector 2 can only rotate in one direction, that is, the movable contact 10 can only move toward one end of 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 member 3 will not fall off the copper bus or cable. When the snap 9 is withdrawn and no longer interferes with the ratchet 8, the socket connector 2 can rotate freely. At this time, the jaws can loosen the copper bus or cable, which greatly improves safety and is convenient and quick to operate. Whether the front end jack 4 is connected to the plug or the rear end jaws are connected to the copper bus or cable, this socket is very convenient, and at the same time greatly improves the connection stability and safety during use.

[0034] According to a clamp-type socket of some embodiments of the present invention, a positioning groove 13 is provided on the outer wall of the shell 1, a rotating shaft 14 is provided in the middle of the positioning groove 13, a rotating hole 15 is opened in the middle of the buckle 9, the rotating shaft 14 is passed through the rotating hole 15, and a pressing portion 16 and a clamping portion 17 are respectively provided on both sides of the rotating hole 15. A positioning hole 18 is passed through the bottom of one end of the positioning groove 13, and the clamping portion 17 is arranged corresponding to the positioning hole 18. A first clamping block 19 is provided at the bottom of the clamping portion 17, and the first clamping block 19 is arranged corresponding to the ratchet 8. A first introduction slope 20 is provided at one end of the first clamping block 19 close to the rotating hole 15, and a first abutting plane 21 is provided at one end of the first clamping block 19 away from the rotating hole 15. Specifically, by setting the rotating shaft 14, the buckle 9 can rotate, the clamping part 17 can extend into the ratchet 8 through the positioning hole 18 to cooperate with the ratchet 8, and the first clamping block 19 is clamped with the tooth groove of the ratchet 8, so that the socket connector 2 cannot be reversed. When the pressing part 16 is pressed downward, the clamping part 17 is lifted, so that the first clamping block 19 extends from the tooth groove of the ratchet 8, and the socket connector 2 can be reversely rotated at this time. The above structure is easy to operate, and the socket connector 2 can be reversely rotated by pressing the pressing part 16 to loosen the jaws. It can be understood that the ratchet 8 can rotate when it rotates from one side of the first introduction slope 20 to the other side, and cannot rotate when it rotates from one side of the first abutment plane 21 to the other side.

[0035] According to some embodiments of the present invention, a clamp-type socket is provided with a second clamping block 22 at the bottom of the clamping portion 17, the second clamping block 22 is located at the end of the first clamping block 19 close to the rotating hole 15, the end of the second clamping block 22 close to the rotating hole 15 is provided with a second introduction slope 23, the end of the second clamping block 22 away from the rotating hole 15 is provided with a second abutment plane 24, and the radial length of the second clamping block 22 is smaller than the radial length of the first clamping block 19. Specifically, the provision of the second clamping block 22 can better prevent the socket connector 2 from rotating. It can be understood that since the rotation radius of the clamping portion 17 along the rotating shaft 14 is smaller than the rotation radius of the socket connector 2, if the cross-section of the second clamping block 22 is the same as the cross-section of the tooth groove of the ratchet 8, it is difficult for the second clamping block 22 to completely withdraw from the tooth groove of the ratchet 8, and it is easy to get stuck. By setting the radial length of the second clamping block 22 to be smaller than the radial length of the first clamping block 19, the depth of the second clamping block 22 in the tooth groove of the ratchet 8 is shallow, which is easy to withdraw and will not get stuck. The above-mentioned structural setting can improve the stability of the cooperation between the ratchet 8 and the clamping portion 17.

[0036] It can be understood that the axial direction and the radial direction in the present invention refer to the axial direction and the radial direction of the insertion hole 4 .

[0037] According to some embodiments of the present invention, a jaw - type socket is provided. An assembly hole 25 is formed at the bottom of the positioning groove 13. A spring (not shown) is disposed in the assembly hole 25, and the top of the spring is connected to the bottom of the pressing portion 16. Specifically, when the ratchet wheel 8 rotates and the engaging portion 17 slides into the next tooth groove of the ratchet wheel 8, under the influence of the restoring force of the spring 26, the engaging portion 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 wheel 8. Similarly, when unlocking by pressing the pressing portion 16, when the pressing portion 16 is released, the engaging portion 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 wheel 8, improving safety.

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

[0039] According to some embodiments of the present invention, for a jaw - type socket, when the movable contact member 10 is located at the end closest to the screw hole 7, the distance from the movable contact member 10 to the piercing elastic piece 12 is L1; the length of the tooth groove of the ratchet wheel 8 in the axial direction is L2; the length of the first clamping block 19 in the axial direction is L3. Then, the relationship among L1, L2, and L3 satisfies: L1 < L2 + L3. To ensure that at any position of the movable contact member 10 in the movable groove 6, the first clamping block 19 can interfere with the ratchet wheel 8 and cooperate with the ratchet wheel 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 wheel 8 can extend into the clearance space 27. Let the length of the clearance space 27 in the axial direction be L4. Then, the relationship among L1, L3, and L4 satisfies: L1 < L3 + L4. Satisfying the above formula ensures that the clearance space 27 covers the movement range of the ratchet wheel 8 in the axial direction.

[0041] 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. The two ends of the guiding groove 29 are respectively communicated with the rotation groove 28 and the outer side of the conductive member 3. The locking hole 30 is provided on the inner wall of the rotation groove 28 away from the movable groove 6, and the two ends in the radial direction of the locking hole 30 respectively penetrate through the jack 4 and the outer side of the conductive member 3. 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 removed, 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 above structure, there are many rotation locking methods for sockets and plugs in the prior art, which are not described in detail here.

[0043] According to a clamp-type socket of some embodiments of the present invention, the movable contact 10 is provided with a first positioning hole 31, the rear end of the conductive member 3 is provided with a second positioning hole 32, a floating screw 33 is provided between the first positioning hole 31 and the second positioning hole 32, a limiting block 34 is convexly provided on the top of the movable contact 10, a limiting groove 35 is provided on the top inner wall of the movable groove 6, and 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 conductive member 3 is rotated by cooperating with the limiting block 34 and the limiting groove 35, so that the movable contact 10 can move within a certain range, while maintaining a stable position and not rotating, which is more conducive to piercing the terminal 12 and piercing the insulation layer.

[0044] In the clamp-type socket described in this embodiment, the upper and lower ends of the fixed contact 11 are provided with a slot 36, and the upper and lower ends of the piercing spring 12 are provided with a block 37, and the block 37 is engaged with the slot 36. Specifically, the piercing spring 12 is engaged with the slot 36 on the fixed contact 11 through the block 37, which simplifies the installation process of the piercing spring 12 and also ensures the stability of the piercing spring 12 during use. This design is conducive to improving the overall stability and durability of the socket.

[0045] It is understandable that the piercing spring piece 12 may also be disposed on the movable contact member 10 , with the same effect.

[0046] In the clamp-type socket described in this embodiment, the front end of the conductive member 3 is provided with an insulating sleeve 38. Specifically, the insulating sleeve 38 at the front end of the conductive member 3 can effectively prevent accidental touch, thereby increasing the safety of use.

[0047] In the clamp-type socket described in this embodiment, a central axis 39 is provided in the middle of the jack 4, and an insulating cap 40 is provided at the front end of the central axis 39. Specifically, the insulating cap 40 at the front end of the central axis 39 can play a certain insulating role, thereby increasing the safety performance of the socket.

[0048] In the clamp-type socket described in this embodiment, the outer periphery of the fixed contact 11 and the movable contact 10 is provided with a finger-touch-proof baffle 41. Specifically, the design of the finger-touch-proof baffle 41 can effectively prevent the user from accidentally touching the live parts, thereby increasing the safety of the socket. This is particularly important for families with children or pets, and can effectively reduce the risk of accidental electric shock.

[0049] It is understandable that the outer periphery of the conductive member 3 is provided with an annular groove 42, and the inner wall of the socket connector 2 is provided with a protrusion 43 extending into the annular groove 42 to achieve axial positioning. Both sides of the conductive member 3 are provided with a limiting plane 44, and the socket connector 2 abuts against the limiting plane 44, so that when the socket connector 2 rotates, the conductive member 3 is driven to rotate synchronously.

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