Description

Technical Field

[0001] The present invention specifically relates to a connection terminal for connecting conductors and an electronic device using the connection terminal. Background Technology

[0002] Existing terminal block structures typically fall into the following categories: threaded, lever-operated, button-operated, and crimp-type, etc. All of these structures require significant external force or tools for operation, which is time-consuming and labor-intensive. However, the requirement for terminal blocks is to achieve a simple and labor-saving conductor insertion connection structure.

[0003] As disclosed in Patent Document 1, a connection device, connection terminal, and electronic device include a current bar (110), a clamping spring (111) having a retaining leg (112) and a clamping leg (113), wherein the clamping leg (113) is movable to a clamping position and a release position, a conductor connection space (124) is formed between a segment (114) of the current bar (110) and the clamping leg (113) of the clamping spring (111), and a movably arranged guide element (115). It is effectively connected to the clamping leg (113) of the clamping spring (111), wherein the clamping leg (113) can be held in the release position by a guide element (115), and an actuating element (129) by which the guide element (115) can be moved to move the clamping leg (113) of the clamping spring (111) from the clamping position to the release position, wherein the clamping spring (111) is arranged between the section (114) of the current bar (110) and the actuating element (129).

[0004] It requires tools to control the manipulator, and the required conductor insertion force is relatively large, necessitating a conductor with a large diameter to achieve triggering.

[0005] Patent document 1CN114730995A. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a connector terminal for connecting conductors. The terminal comprises a housing with a cavity and an insertion channel; a conductive element disposed within the cavity for electrical connection with the inserted conductor; an elastic element disposed within the cavity and surrounded by the conductive element, wherein the conductor can be clamped between the elastic element and the conductive element; a movable element movably disposed within the cavity for restricting and driving the movement of the elastic element; and a control element rotatably connected to the housing, one end of which extends into the cavity and drives the movable element. The elastic element exists in a ready-to-trigger state and a clamped state. By rotating the control element, the movable element drives the elastic element to move, placing it in the ready-to-trigger state. When the elastic element is in the ready-to-trigger state, the conductor can pass through the insertion channel. When the conductor passes through the insertion channel and contacts the elastic element, the elastic element rebounds, switching from the ready-to-trigger state to the clamped state, thereby clamping the inserted conductor.

[0007] In several embodiments, the movable element has a top surface and two side surfaces symmetrically located on both sides of the top surface; a connector is provided protruding from the top surface; the side surfaces include a main body and contact ends one, two, three, four and five sequentially arranged around the main body.

[0008] In several embodiments, the control element extends into the cavity and has a connector two. The connector two and the connector one are in contact. When the connector one rotates to contact the connector two, the control element drives the moving element to rotate and translate.

[0009] In several embodiments, the elastic element includes an elastic segment 1, an elastic segment 2, and an elastic segment 3 connected in sequence. The elastic segment 1 is provided with a snap-fit ​​segment 1, the elastic segment 2 is provided with a snap-fit ​​segment 2, and the width of the elastic segment 3 is greater than the width of the snap-fit ​​segment 2.

[0010] In several embodiments, the conductive element includes conductive segment one, conductive segment two, conductive segment three and conductive segment four connected in sequence, wherein conductive segment two is located inside the movable element, and conductive segment four is disposed opposite to conductive segment one and located on the side away from the control element.

[0011] In several embodiments, a limiting groove 1, a limiting groove 2, and a limiting protrusion are provided in the cavity. The limiting groove 1 is used to accommodate the conductive segment 1, the limiting groove 2 is used to accommodate the contact end 5, and the elastic segment 1 and the elastic segment 2 are arranged around the limiting protrusion.

[0012] In several embodiments, the insertion channel corresponds to the position of the fourth conductive segment, and the conductor can be inserted into the insertion channel and pass through the moving element in the ready-to-trigger state until it contacts the third phase of the missile segment, thereby switching to the locked state.

[0013] In several implementations, when the state to be triggered is switched to the wire-pressing state, the conductor passes through the insertion channel until it contacts the elastic element. The elastic element rebounds. At this time, contact end one abuts against conductive section one, contact end five abuts against the limiting groove two, and contact end four abuts against elastic section three. The conductor is clamped between snap-fit ​​section one and conductive section two to achieve wire-pressing connection.

[0014] When the circuit is reset from the wire-pressed state to the ready-to-trigger state, the control element is rotated, and the second connector contacts the first connector, thereby pushing the movable element until the first contact end disengages from the first conductive section, the second contact end contacts the first locking section and compresses the first locking section, the fourth contact end disengages from the third elastic section, the third contact end enters the second locking section, and the fifth contact end moves outward from the second limiting groove. At this time, the conductor can be inserted into or pulled out of the insertion channel.

[0015] In several embodiments, the housing includes a main housing portion and an end cap. The main housing portion is provided with a plurality of detection holes, which extend into the cavity and correspond to the positions of conductive segment one and conductive segment two.

[0016] In several embodiments, the main shell and the end cap are fitted together by an insertion joint.

[0017] Furthermore, the objective according to the invention can be achieved by an electronic device having at least one connection terminal formed and further developed as described above.

[0018] This invention allows the terminals to be in a ready-to-trigger state at the factory, eliminating the need for tools and other operating steps. Simply insert the wire, greatly improving wiring time and convenience. Furthermore, the overall structural design gives it a very small triggering force, which can trigger the insertion of small-diameter conductors to lock the conductor and achieve connection.

[0019] The control element can meet the terminal's triggering state while horizontally recessed into the housing, eliminating the need to pry the control element up, thus reducing the space occupied and facilitating transportation and storage.

[0020] At the same time, by controlling the movement of the control element, the compression action of the elastic element can be repeated, that is, the formation of the triggering state can be repeated.

[0033] The embodiments of the present invention will be described in detail below. In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0034] The terminology used herein is intended to explain the embodiments and is not intended to limit and / or restrict the invention.

[0035] The present invention provides a connecting terminal for connecting conductors, which is used for connecting conductors, especially for connecting conductors with small diameter and small trigger force.

[0036] like Figure 1-2 As shown, the connection terminal in this embodiment is mainly composed of a housing 1 and a conductive element 2, an elastic element 3, a movable element 4 and a control element 5 disposed in the housing 1.

[0037] and combined with appendix Figure 3 The housing 1 is composed of a main housing 11 and an end cap 12, which are connected by a plug-in structure for easy assembly and disassembly. The main housing 11 has a cavity 111 and an insertion channel 112. The insertion channel 112 is for introducing externally inserted components into the cavity 111. The cavity 111 is used to accommodate the conductive element 2, the elastic element 3, the movable element 4, and the control element 5. The cavity 111 is provided with a limiting groove 101, a limiting groove 102, and a limiting protrusion 103. The limiting groove 101 is located on the upper side close to the insertion channel 112, the limiting groove 102 is located away from the insertion channel 112, and the limiting protrusion 103 is located on the lower side close to the insertion channel 112.

[0038] and combined with appendix Figure 4 and Figure 5 The control element 5 is rotatably connected to the housing 1. One end of the control element 5 extends into the cavity 111 and can drive the movable element 4 to move. The end extending into the cavity 111 has a connecting body 2 51, which protrudes from the end face of the control element 5.

[0039] and combined with appendix Figure 6 The movable element 4 is movably disposed within the cavity 111. The movable element 4 is used to restrict and drive the movement of the elastic element 3. The movable element 4 has a top surface 41 and two symmetrical and perpendicularly located sides 42 on both sides of the top surface 41, thereby forming a generally U-shaped structure.

[0040] A first connector 411 is provided protruding on the top surface 41. The second connector 51 is in contact with the first connector 411. That is, the first connector 411 can contact the second connector 51 when rotating. The protruding second connector 51 can increase the radius and reduce the rotation angle. The operation requirement of resetting can be achieved by rotating the control element 5 by 45 degrees.

[0041] The side 42 includes a main body 420 and contact end 1 421, contact end 2 n, contact end 3 423, contact end 424 and contact end 5 425 that are sequentially arranged around and protrude from the main body 420.

[0042] and combined with appendix Figure 7The elastic element 3 is disposed within the cavity 111 and surrounded by the conductive element 2. The conductor can be locked between the elastic element 3 and the conductive element 2. The elastic element 3 includes an elastic segment 31, an elastic segment 32, and an elastic segment 33 connected in sequence. The elastic segment 31 is provided with a snap-fit ​​segment 311, which is in contact with the contact end 422. The elastic segment 32 is provided with a snap-fit ​​segment 322, which is in contact with the contact end 423. The tail end of the elastic segment 33 is in contact with the contact end 424.

[0043] Both snap-fit ​​section 311 and snap-fit ​​section 322 are concave stepped surface structures formed at the corresponding elastic section positions, which facilitates contact with the corresponding contact end to achieve limiting.

[0044] The elastic segment 31 and elastic segment 32 are arranged around the limiting protrusion 103, that is, the connection position of the two is arc-shaped and surrounds the outside of the limiting protrusion 103, thereby limiting the displacement range of the elastic element 3.

[0045] and combined with appendix Figure 8 The conductive element 2 is disposed in the cavity 111 for electrical connection with the inserted conductor. It is composed of conductive segment 1 21, conductive segment 22, conductive segment 3 23 and conductive segment 4 24 connected in sequence. The conductive segment 22 is located inside the movable element 4, and the conductive segment 1 21 is in contact with the contact end 421. The connection between the conductive segment 1 21 and the conductive segment 22 also forms a stepped structure, thereby forming a limiting fit with the contact end 421.

[0046] The first conductive segment 21 is inserted into the first limiting groove 101. Correspondingly, the fifth contact end 425 makes contact with the third conductive segment 23. The second limiting groove 102 is used to accommodate the fifth contact end 425. A stepped surface structure limiting segment 231 is also formed at the position of the third conductive segment 23 and the second conductive segment 22, thereby providing the fifth contact end 425 with room to move.

[0047] Correspondingly, conductive segment 4 24 is positioned opposite to conductive segment 1 21 and located on the side away from control element 5. That is, if control element 5 is set to a position above one side, conductive segment 1 21 is also located above, while conductive segment 4 is located below.

[0048] It should be noted that the insertion channel 112 corresponds to the position of the elastic segment 33. That is, the conductor can be inserted into the insertion channel 112 and pass through the movable element 4 in the ready-to-trigger state until it contacts the elastic segment 33, thereby switching to the locked state.

[0049] Meanwhile, two detection holes 113 are provided on the main shell 11. The two detection holes 113 extend to the cavity 111 and correspond to the positions of conductive section 1 21 and conductive section 2 22, which facilitates testing whether the circuit is connected.

[0050] like Figure 2 As shown, the terminal block is in the crimped state at this time, that is, after the conductor is inserted. At this time, contact end 421 abuts against conductive section 21, contact end 425 abuts against the upper inner wall of limiting groove 102, and contact end 424 abuts against elastic section 33. Without external force, it cannot continue to rotate counterclockwise, and the conductor is clamped between the end 31a of the snap-fit ​​section 311 and conductive section 22, thus realizing the crimped connection.

[0051] like Figure 9-10 As shown, when it is necessary to reset to the trigger-ready state, the clockwise rotation of the control element 5, from 0 degrees to 45 degrees, can achieve the reset. Specifically, the second connector 51 contacts the first connector 411, thereby pushing the movable element 4. The movable element 4 rotates counterclockwise and translates to the left, causing the first contact end 421 to disengage from the first conductive section 21. The two adjacent inclined surfaces of the second contact end 422, inclined surface a and inclined surface b, come into contact with the first locking section 311, causing it to be compressed. The third contact end 423 gradually enters the second locking section 322, the fourth contact end 424 begins to disengage from the third elastic section 33, and the fifth contact end 425 also moves outward from the second limiting groove 102. It should be noted that when the horizontal translation to the left occurs, since the length of contact end 424 is less than the length of contact end 423, contact end 424 first moves away from elastic segment 33, and then contact end 423 moves into snap-fit ​​segment 322.

[0052] like Figure 11 As shown, after the control element 5 has fully rotated, it can be reset to the recessed housing. The elastic segment 31 is pressed down, and the elastic element 3 is in a compressed and ready-to-trigger state. The contact end 424 completely disengages from the elastic segment 33, causing the elastic segment 33 to move upward and reset. The contact end 421 moves to the position below the conductive segment 21 and is abutted and restricted by the conductive segment 21. The contact end 423 enters the snap-fit ​​segment 322. At this time, the top surface of the movable element 4 is in a horizontal state, releasing a channel for the conductor to be inserted.

[0053] Subsequently, when the conductor 1000 penetrates the insertion channel 112 and comes into contact with the elastic element 3, that is, when the conductor 1000 contacts the elastic segment 33, since the width of the elastic segment 33 is greater than the width of the snap-fit ​​segment 322, the deformation caused by the external force on the elastic segment 33 is transmitted to the snap-fit ​​segment 322, which causes the contact end 423 to disengage from the snap-fit ​​segment 322. At the same time, the snap-fit ​​segment 311 is subjected to the horizontal pushing force at the inclined surface b position of the contact end 422, which causes the elastic segment 31 to rebound. The end 31a of the snap-fit ​​segment 311 presses the conductor, thus achieving wire pressing.

[0054] It should be noted that the conductor 1000 in this embodiment refers to a material that can conduct current, and is not limited to a certain type or class of wire material.
