Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and specifically to a connecting terminal. Background Technology

[0002] During the use of conductive equipment, the "touch-connect" terminal block can easily and efficiently connect conductive wires. However, with existing technology, on-site personnel need to use tools to press the operating element during wiring, so that the operating element drives the spring in the terminal block to a certain locking position, then insert the conductive wire to trigger the spring to move the operating element upward, and then the spring and the housing work together to clamp the conductive wire.

[0003] In the above process, the same spring sheet has to perform both the triggering and clamping functions, which makes the overall structure of the spring sheet more complex. This requires higher precision in mold design and processing, increases production costs, and is not conducive to stable mass production. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] The following is combined with Figures 1 to 12 The following describes embodiments of the present invention.

[0039] According to an embodiment of the present invention, a connecting terminal is provided, comprising: a housing 3 having an insertion channel 301 and an operation channel 303, the insertion channel 301 and the operation channel 303 being arranged at an angle, the insertion channel 301 being used to guide the insertion of a conductive wire 6; a wire clamping spring 5 disposed within the housing 3 and located on one side of the insertion channel 301, the wire clamping spring 5 being switchable between a clamping position and an open position; an operating element 4 disposed within the housing 3 and adapted to move along the operation channel 303; and a trigger spring 1 disposed within the housing 3 and located at the bottom of the insertion channel 301, the trigger spring 1 having a fixed end 103 and a trigger end 101, the fixed end 103 of the trigger spring 1 being fixedly disposed, and the trigger end 101 forming an elastic arm and having a tendency to elastically deflect toward the wire clamping spring 5 and the operating element 4; wherein, when the operating element 4 moves along the operation channel 303, it can engage with the trigger spring 1, and hold the wire clamping spring 5 in the open position by cooperating with the trigger spring 1;

[0040] When the conductive wire 6 is inserted along the insertion channel 301, the conductive wire 6 acts on the trigger spring 1, causing the trigger spring 1 to disengage from the operating element 4, and the clamping spring 5 then switches from the open position to the clamping position.

[0041] In this application, by having the trigger spring 1 perform the triggering function and the wire clamping spring 5 perform the wire clamping function, the structure of the trigger spring 1 and the wire clamping spring 5 is simplified, the molds for manufacturing the trigger spring 1 and the wire clamping spring 5 do not need to be complicated, the production cost of enterprises is reduced, and stable mass production can be carried out.

[0042] In the locked state, by extending the abutment portion 403 of the operating element 4 into the locking space 106, the locking space 106 contacts the operating element 4, thus resisting a portion of the restoring force on the operating element 4. The pressing tool bears the remaining portion of the restoring force, thereby reducing the rebound force borne by the tool. Alternatively, the locking space 106 can completely bear the restoring force on the operating element 4, without the tool bearing the rebound force, facilitating subsequent operations. In the locked state, the trigger spring 1 provides the force to prevent the operating element 4 from returning to the abutment state, instead of the clamping spring 5, avoiding the clamping spring 5 providing two forces simultaneously and extending its service life.

[0043] In one embodiment, a fluid carrier 2 is further included, which is disposed within the housing 3. The fluid carrier 2 includes a first fixing section 201 and a second fixing section 202 that are bent and connected to form an L-shaped structure. The first fixing section 201 is provided with a first fixing hole 204. The fixing end 103 of the trigger spring 1 is bent to form an L-shaped structure and is connected to a fixing plate 104. The fixing end 103 is fixed by inserting the fixing plate 104 into the first fixing hole 204.

[0044] The fixing plate 104 and the first fixing hole 204 of the fluid carrier 2 are used to fix the trigger spring 1. It should be noted that there is only one fixing plate 104 in this embodiment.

[0045] In one embodiment, such as Figure 3 , Figure 7 and Figure 8 As shown, the trigger spring 1 also includes a connecting section 102, which is connected to the fixed end 103 and the trigger end 101 respectively. The fixed end 103, the connecting section 102, and the trigger end 101 form a locking space 106. In the clamped position, one side of the trigger end 101 is adapted to be in contact with the fluid carrier 2, and the other side of the trigger end 101 is adapted to be in contact with the side of the abutment portion 403 of the operating element 4. In the open position, the trigger end 101 is separated from the fluid carrier 2, and the abutment portion 403 of the operating element 4 extends into the locking space 106. The locking space 106 restricts the abutment portion 403, so that the clamping spring 5 is in the open position.

[0046] In one embodiment, such as Figure 7 , Figure 8As shown, the width of the connecting segment 102 is smaller than the width of the trigger end 101, and the width of the connecting segment 102 is smaller than the width of the fixed end 103. A locking space 106 is formed by the first side 108 of the connecting segment 102, the second side of the trigger end 101, and the third side 109 of the fixed end 103. The second side and the third side 109 are located on the same side of the first side 108. It should be noted that the second side is the side of the trigger end 101 facing the fixed end 103, and the third side 109 is the side of the fixed end 103 facing the trigger end 101, thus forming the locking space 106. The locking space 106 limits the movement of the operating element 4. In this embodiment, there are two locking spaces 106, that is, one locking space 106 is provided on each side of the connecting segment 102, and one locking space 106 corresponds to one abutment part 403. In this embodiment, the trigger spring 1 is made of an elastic conductive metal material, such as copper.

[0047] In this embodiment, as Figure 8 As shown, an anti-slip strip 107 is provided on the side of the trigger end 101 facing the contact portion 403. The anti-slip strip 107 is provided to prevent the connector of the conductive wire 6 from sliding arbitrarily when in contact with the trigger end 101.

[0048] In one embodiment, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the trigger spring 1 also includes a locking part 105, which is connected to the second side. The locking part 105 is arc-shaped, and the side wall of the second fixing section 202 is provided with a locking space 207. In the clamped position, the locking part 105 extends into the locking space 207. When switching from the clamped position to the open position, the abutment part 403 of the operating element 4 moves toward the fixing end 103 of the trigger spring 1 until the abutment part 403 of the operating element 4 enters the locking space 106. Since the trigger end 101 is no longer in contact with the abutment part 403, the trigger end 101 moves away from the fluid carrier 2, thereby driving the locking part 105 to move outside the locking space 207 of the fluid carrier 2. The locking part 105 limits the abutment part 403 of the operating element 4 so as to receive a part of the restoring force of the operating element 4. It should be noted that each side of the second fixing section 202 is provided with a locking space 207.

[0049] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 10 and Figure 11As shown, the operating element 4 is slidably connected to the operating channel 303. The central axis of the operating channel 303 is perpendicular to the central axis of the insertion channel 301. The operating element 4 is provided with a wire-passing hole 401. The insertion channel 301 and the wire-passing hole 401 are correspondingly arranged, and the cross-section of the wire-passing hole 401 is larger than the cross-section of the insertion channel 301. Because the cross-section of the wire-passing hole 401 is larger than the cross-section of the insertion channel 301, the space of the wire-passing hole 401 is always corresponding to the insertion channel 301 when the housing 3 moves. Figure 10 , Figure 11 As shown, the outer side of the housing 3 is provided with slide rails 404. The slide rails 404 cooperate with the slide groove in the operation channel 303 to realize the sliding of the control element 4 relative to the housing 3. It should be noted that the housing 3 and the control element 4 in this embodiment are both made of insulating material.

[0050] In this embodiment, as Figure 2 , Figure 4 , Figure 6 and Figure 10 As shown, the control element 4 also includes a clearance space 407. In the open position, the trigger end 101 of the trigger spring 1 moves toward the direction away from the fluid 2, and the trigger end 101 enters the clearance space 407.

[0051] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 12 As shown, one end of the wire clamping spring 5 is a limiting part 501, which is provided with a gripper 502. The fluid carrier 2 is provided with a second fixing hole 205, and the gripper 502 extends into the second fixing hole 205. In the locked state, the limiting part 501 contacts the bottom surface of the abutment part 403 of the operating element 4 to provide support for the abutment part 403. In this embodiment, the central axis of the first fixing hole 204 and the central axis of the second fixing hole 205 are arranged perpendicularly, and the second fixing hole 205 cooperates with the gripper 502 to fix the limiting part 501 of the wire clamping spring 5. In the open position, the limiting part 501 contacts the bottom surface of the abutment part 403 of the operating element 4, and the locking part 105 contacts the top surface of the abutment part 403 of the operating element 4 to restrict the abutment part 403, thereby bearing part of the restoring force of the abutment part 403. It should be noted that there are two grippers 502 for fixed connection with the fluid carrier 2, and the clamping spring 5 is made of an elastic conductive metal material, such as copper.

[0052] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 , Figure 10 and Figure 12 As shown, the wire clamping spring 5 also includes a return section 504 and a support section 503. The support section 503 is connected to the return section 504 and the limiting section 501, respectively. The operating element 4 is provided with a guide section 405 facing the wire clamping spring 5. The guide section 405 is arc-shaped. The return section 504 abuts against the guide section 405. In the open position, the return section 504 is in a compressed state, and the support section 503 is in contact with the operating element 4 and the support column 302 in the housing 3, respectively. In this embodiment, the wire clamping spring 5 is integrally formed, the support section 503 is arc-shaped, and the return section 504 is in a compressed state in the open position. When switching from the clamping position to the open position, the return section 504 moves along the guide section 405, the operating element 4 moves towards the wire clamping spring 5, the distance between the return section 504 and the limiting section 501 gradually decreases, and the return section becomes compressed to provide a rebound force to the operating element 4. The support section 503 is supported by the support column 302.

[0053] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, the current carrier 2 also includes a third fixing section 203. The end of the second fixing section 202 facing away from the first fixing section 201 is connected to the third fixing section 203. The first fixing section 201 and the third fixing section 203 are respectively located on both sides of the second fixing section 202. The first fixing section 201 is fixedly connected to the housing 3, and the third fixing section 203 extends into the wire hole 401. It should be noted that the first fixing section 201, the second fixing section 202 and the third fixing section 203 are integrally formed. When the operating element 4 slides relative to the housing 3, the third fixing section 203 will not contact the inner wall of the wire hole 401. In the clamping position, the lower surface of the third fixing section 203, the two side walls of the wire hole 401 and the bottom surface enclose a space for clamping the conductive wire 6. The material of the current carrier 2 is a conductive material (e.g., copper), and the current carrier 2 transmits current to the conductive wire 6.

[0054] In this embodiment, as Figure 9 As shown, the second fixed section 202 has a support strip 206 on the side facing the trigger spring 1. The support strip 206 is a protrusion. The support strip 206 is provided to avoid the trigger spring 1 from being completely attached to the second fixed section 202, and to apply a force to the trigger spring 1 away from the second fixed section 202.

[0055] In one embodiment, such as Figure 10 , Figure 11As shown, a support block 402 is provided on the inner wall of the wire hole 401 to support the conductive wire 6. The space between the third fixing section 203 and the support block 402 is used to accommodate the conductive wire 6. There are two support blocks 402. When the conductive wire 6 enters the wire hole 401, the space between the third fixing section 203 and the support block 402 accommodates the conductive wire 6, thereby limiting the arbitrary shaking of the conductive wire 6.

[0056] A method of using a terminal block, comprising an abutting state, a locking state, and a wire clamping state, includes the following steps:

[0057] (1) In the contact state, the wire clamping spring 5 is in a free state, the contact part 403 of the operating element 4 is in contact with one side of the trigger end 101, the other side of the trigger end 101 is in contact with the second fixed section 202 of the fluid carrier 2, the fixed end 103 of the trigger spring 1 is connected to the first fixed section 201 through the fixed plate 104, and the limiting part 501 of the wire clamping spring 5 is fixedly connected to the second fixed section 202 through the gripper 502;

[0058] (2) When switching from the contact state to the locking state, the on-site personnel apply pressure to the drive part 406 of the control element 4 with a tool, so that the control element 4 moves toward the wire clamping spring 5. The return part 504 moves along the guide section 405 of the control element 4. The distance between the return part 504 and the limit part 501 gradually decreases. The return section becomes compressed to provide a rebound force to the control element 4 until the contact part 403 of the control element 4 enters into the locking space 106. At the same time, the trigger end 101 moves away from the fluid 2 to enter the clearance space 407. The insertion channel 301 and the wire hole 401 are correspondingly set. At this time, the wire clamping spring 5 is in the open position to lock the control element 4, so that the on-site personnel can remove the tool.

[0059] (3) In the locked state, the central axis of the insertion channel 301 coincides with the central axis of the wire hole 401, the abutment part 403 of the operating element 4 enters into the locking space 106, and the trigger end 101 enters into the clearance space 407.

[0060] (4) When the locking state is switched to the clamping state, the conductive wire 6 extends into the wire hole 401 through the insertion channel 301. The end of the conductive wire 6 contacts the trigger end 101 to apply a force to the trigger end 101 to move in the direction of the fluid carrier 2. The trigger end 101 moves in the direction of the fluid carrier 2, so that the abutment part 403 of the operating element 4 is disengaged from the locking space 106. Under the action of the restoring force of the return section, the operating element 4 moves in the direction away from the clamping spring 5.

[0061] (5) In the clamped state, the space between the third fixed section 203 and the support block 402 accommodates the conductive wire 6 to limit the arbitrary shaking of the conductive wire 6. The return section provides the force to clamp the conductive wire 6. The locking part 105 enters into the locking space 207. The current of the current carrier 2 is transmitted to the conductive wire 6 through the trigger end 101. At this time, the clamping spring 5 is in the clamped position.

[0062] (6) When switching from the clamping state to the contact state, the on-site personnel use tools to apply pressure to the drive unit 406, causing the control element 4 to move toward the clamping spring 5, pull out the conductive wire 6, and release the pressure to make the return section drive the control element 4 move to achieve the contact state.

[0063] The terminal block provided by this utility model has the following advantages: (1) In this application, by having the trigger spring 1 undertake the triggering function and the wire clamping spring 5 undertake the wire clamping function, the structure of the trigger spring 1 and the wire clamping spring 5 is simplified, the mold for manufacturing the trigger spring 1 and the wire clamping spring 5 does not need to be complicated, the production cost of the enterprise is reduced, and batch stable production can be carried out; (2) The locking part 105 is set as an arc shape, so that when the locking part 105 cooperates with the abutment part 403, it is easier for the abutment part 403 to enter or leave the locking space 106 more smoothly, the service time is longer and the stability is better; (3) The operating element 4 can directly drive the wire clamping spring 5 to move without the need for additional parts. The two sides of the operating element 4 are respectively provided with guide sections 405, and the two sides are connected by a connecting rod to have higher strength. When the operating element 4 compresses the wire clamping spring 5, the two sides of the operating element 4 will not expand or deform due to the presence of the connecting rod. The entire operation process is more stable and reliable; (4) The fluid carrier 2 fixes the fixed end 103 and the limiting part 501 respectively. When the trigger spring 1 is pressed against the fluid carrier 2, the support bar 206 can act as the fulcrum of the trigger spring 1 and automatically generate internal stress that makes the trigger spring 1 move away from the fluid carrier 2, so that the operating element 4 can enter the locking space 106 when it is pressed down; (5) The trigger spring 1 is designed as a lever structure that saves effort. That is, the locking lever arm is shorter than the trigger lever arm. Only a small triggering force is needed (the conductor 6 with a small diameter can achieve this) to achieve the switching from the locking state to the clamping state; (6) The arc setting of the locking part 105 means that when the trigger end 101 of the trigger spring 1 is not under force, if the operating element 4 is given a force that moves away from the clamping spring 5, the locking part 105 will produce a tightening effect on the operating element 4, so that the operating element 4 will not automatically leave the locking space 106.

[0064] As an alternative implementation, the number of locking spaces 106 may also be one.

[0065] As an alternative implementation, the number of grippers 502 can be 1, 3, 4 or even more, with one gripper 502 corresponding to one second fixing hole 205.

[0066] As an alternative implementation, the number of fixing plates 104 may also be 2 or 3, and one fixing plate 104 corresponds to one first fixing hole 204.

[0067] As an alternative implementation, in the abutting state, the drive portion 406 of the control element 4 may partially extend out of the housing 3, or the surface of the drive portion 406 of the control element 4 may be flush with the surface of the housing 3.

[0068] As an alternative implementation, the materials of the trigger spring 1, the clamping spring 5, and the current carrier 2 can also be conductive materials such as silver and aluminum.

[0069] As an alternative implementation, the support bar 206 may be disposed on the trigger spring 1 instead of on the second fixed section 202.

[0070] As an alternative implementation, the trigger spring 1 may not have the locking part 105.

[0071] As an alternative implementation, the trigger spring 1 may not be equipped with the anti-slip strip 107.

[0072] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
