Description

Technical Field

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

[0002] In contact-type terminal blocks, wires can be connected easily and efficiently. Currently, most terminal blocks have channels that allow conductive wires to enter. After entering the channel, the conductive wire contacts the trigger plate of the spring. The trigger plate often has a locking part for locking the wire clamping end of the spring. After the wire clamping end separates from the locking part, the wire clamping end and the housing work together to clamp the conductive wire. However, due to the relatively small space inside the housing, the movement distance of the wire clamping end after separating from the locking part is short. This results in the wire clamping end and the housing only clamping a short distance (the distance from the end of the conductive wire to the clamping end) of the conductive wire. The conductive wire is prone to loosening under force, resulting in unreliable connection. Utility Model Content

[0024] 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.

[0025] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0026] According to an embodiment of the present invention, a wire clamping spring is provided, comprising: a body 1, the body 1 having a wire clamping end 102, a trigger end 101 and a locking section 103, the locking section 103 being connected to the trigger end 101 and disposed between the trigger end 101 and the wire clamping end 102, the body 1 having a self-locking state and a wire clamping state, in the self-locking state, the locking section 103 being locked to the wire clamping end 102, and a receiving space being formed between the body 1 and the housing 4, the receiving space being suitable for a conductive wire to extend into; in the wire clamping state, the conductive wire extends into the receiving space, and the end of the conductive wire contacts the trigger end 101 to drive the locking section 103 to separate from the wire clamping end 102, the wire clamping end 102 cooperating with the housing 4 to jointly fix the conductive wire.

[0027] Because the locking section 103 is connected to the trigger end 101, the locking section 103 is closer to the clamping end 102 than the trigger end 101. Even if the clamping section moves a short distance within the housing 4, the locking section 103 will still move closer to the wire clamping end 102. Figure 2 The height of the Z-axis is higher than that of the trigger end 101, and the distance between the clamping end 102 and the end of the conductive wire is longer. That is, the clamping end 102 and the housing 4 will clamp a longer length of conductive wire, which prevents the conductive wire from coming loose when under force and ensures the reliability of the connection.

[0028] In one embodiment, such as Figure 1 , Figure 2 As shown, the locking section 103 also includes a locking part 1032 and a locking plate 1031. The locking plate 1031 is connected to the trigger end 101 through a first connecting section 105. The locking part 1032 extends from the locking plate 1031 toward the clamping end 102. In the self-locking state, the locking part 1032 is locked to the clamping end 102. The locking part 1032 locks the clamping end 102 of the locking plate 1031 to achieve the self-locking state of the clamping spring.

[0029] In one embodiment, such as Figure 1 , Figure 2 As shown, the main body 1 also includes an intermediate fixing section 104. A locking plate 1031 is connected to the intermediate fixing section 104 via a second connecting section 106. The locking part 1032 is arc-shaped, with its arc-shaped opening 1033 facing the intermediate fixing section 104. The arc-shaped locking part 1032 locks the locking plate 1031, allowing the wire clamping end 102 to enter the arc-shaped opening 1033 for locking. It should be noted that in this embodiment, there are two locking parts 1032.

[0030] In one embodiment, such as Figure 1 , Figure 2As shown, the width of the first connecting segment 105 is less than the width of the locking plate 1031, and the width of the first connecting segment 105 is less than the width of the trigger end 101. The width of the second connecting segment 106 is less than the width of the intermediate fixed segment 104, and the width of the second connecting segment 106 is less than the width of the locking plate 1031. The second connecting segment 106 is arc-shaped. The width of the first connecting segment 105 along the Y-axis is less than the width of both the locking plate 1031 and the trigger end 101, allowing the trigger end 101 to move more easily, i.e., unlocking is easier. The width of the second connecting segment 106 along the Y-axis... Figure 2 The width of the second connecting section 106 in the Y-axis direction is smaller than the width of the middle fixed section 104 and the locking plate 1031, and the second connecting section 106 is arc-shaped. This design makes the second connecting section 106 more resistant to yielding, which helps to achieve long-term stability of the function of the second connecting section 106.

[0031] In one embodiment, such as Figure 1 , Figure 2 As shown, the intermediate fixing section 104 includes a first intermediate fixing segment 1042 and a second intermediate fixing segment 1041. The first intermediate fixing segment 1042 is connected to the wire clamping end 102, and the second intermediate fixing segment 1041 is connected to the second connecting segment 106. The first surface 1043 of the first intermediate fixing segment 1042 is adapted to abut against the driving member 2. The first intermediate fixing segment 1042 is arc-shaped. By abutting against the driving member 2, the driving member 2 applies pressure to the first intermediate fixing segment 1042 to drive it to move, causing the body 1 to switch from the wire clamping state to the self-locking state. Figure 2 As shown, the intermediate fixed section 104 also includes a second surface 1045, and the first surface 1043 and the second surface 1045 are located on both sides of the intermediate fixed section 104.

[0032] In one embodiment, such as Figure 1 , Figure 2 As shown, the main body 1 also includes a third connecting segment 107. One end of the third connecting segment 107 is connected to the clamping end 102, and the other end of the third connecting segment 107 is connected to the first intermediate fixing segment 1042. The first connection between the third connecting segment 107 and the clamping end 102 protrudes outward, and the second connection between the third connecting segment 107 and the first intermediate fixing segment 1042 is recessed inward. When the driving member 2 applies force to the first intermediate fixing segment 1042, it will move towards the third connecting segment 107. The outward protrusion and inward recess are used to restrict the position of the driving member 2 at the third connecting segment 107, preventing the driving member 2 from moving along... Figure 3 The direction of the force F in the middle is excessively slipped.

[0033] In one embodiment, such as Figure 1 , Figure 2As shown, the body 1 also includes a contact portion 1044, which is adapted to be fixedly connected to the fluid carrier 3, and the fluid carrier 3 transmits current to other parts of the body 1 through the contact portion 1044. Specifically, the contact portion 1044 is circular. It should be noted that the body 1 in this embodiment is integrally molded, and the body 1 is made of an elastic conductive material, such as copper.

[0034] According to an embodiment of the present invention, another aspect is provided: a contact terminal block including the aforementioned wire clamping spring.

[0035] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes a housing 4 and a fluid carrier 3. The housing 4 is provided with an entry channel 401 and a drive channel 402. The entry channel 401 is suitable for inserting a conductive wire, and the drive channel 402 is suitable for inserting a drive element 2. The fluid carrier 3 is disposed inside the housing 4. In the self-locking state, a receiving space is formed between the inner wall of the fluid carrier 3 and the body 1. Figure 4 , Figure 5 As shown, the fluid-carrying 3 is provided with a first vertical side plate 302. In the self-locking state, an accommodating space is formed between the inner wall of the first vertical side plate 302 and the body 1. Figure 4 , Figure 5 As shown, a guide portion 304 is also provided on the inner wall of the first vertical side plate 302. When the guide portion 304 changes from the self-locking state to the wire clamping state, it guides the entry of the conductive wire, and in the wire clamping state, it prevents the conductive wire from separating from the wire clamping end 102.

[0036] In this embodiment, as Figure 4 , Figure 5 As shown, the fluid-carrying plate 3 further includes a connecting plate 305 and a second vertical side plate 303. The first vertical side plate 302 is connected to the connecting plate 305, and the side of the first vertical side plate 302 is connected to the second vertical side plate 303. A gap is left between the second vertical side plate 303 and the connecting plate 305. It should be noted that the connecting plate 305 has a first vertical side plate 302, a second vertical side plate 303, and a clamping plate 301 on each side. In this embodiment, as... Figure 6 , Figure 7 As shown, one side of the housing 4 is provided with an entry channel 401, a drive channel 402, and a detection hole 403, and the other side of the housing 4 is provided with an entry channel 401 and a drive channel 402. The detection hole 403 is suitable for a detection tool to enter. The detection tool contacts the contact portion 1044 of the wire clamping spring to determine whether the wire clamping spring is energized. Specifically, the detection tool is a voltage tester.

[0037] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the housing 4 also includes a support portion 404 and a first clamping portion 405. The fluid-carrying 3 is provided with a clamping plate 301. The support portion 404 clamps the first intermediate fixed segment 1042, and the first clamping portion 405 and the clamping plate 301 together clamp the second intermediate fixed segment 1041. Figure 4 , Figure 5 As shown, the housing 4 also includes a second clamping part 406, wherein the first clamping part 405 and the clamping plate 301 clamp the second intermediate fixed segment 1041, and the space between the first clamping part 405 and the second clamping part 406 also clamps the second intermediate fixed segment 1041. In this embodiment, the material of the current carrier 3 is a conductive material, such as copper; the material of the housing 4 is an insulating material, such as plastic. In this embodiment, due to the setting of the first clamping part 405, the locking segment 103 is fixed and clamped, so that the distance from the highest point of the first intermediate fixed segment 1042 to the locking segment 103 remains unchanged. This design allows for a wider manufacturing tolerance in the height direction, thereby reducing the manufacturing difficulty of the entire clamping spring.

[0038] A method for using a contact terminal block, having a self-locking state and a wire-clamping state, includes the following steps:

[0039] (1) When in the self-locking state, the clamping end 102 is located in the locking part 1032, the middle fixed section 104 is in a compressed state, a receiving space is formed between the body 1 and the first vertical side plate 302, and the support part 404 is in contact with the second surface 1045 of the middle fixed section 104.

[0040] (2) When switching from the self-locking state to the clamping state, the conductive wire enters from the entry channel 401. Under the guidance of the guide part 304, the conductive wire comes into contact with the trigger end 101. The end of the conductive wire applies force to the trigger end 101. The trigger end 101 drives the first connecting section 105. The first connecting section 105 drives the locking plate 1031. The locking plate 1031 drives the locking part 1032 to separate from the clamping end 102. The middle fixing section 104 drives the clamping end 102 to move toward the conductive wire. The conductive wire and the first vertical side plate 302 clamp the conductive wire together.

[0041] (3) When in the clamped state, the clamping end 102 and the inner wall of the first vertical side plate 302 work together to clamp the conductive wire;

[0042] (4) When switching from the clamping state to the self-locking state, the driving member 2 enters the housing 4 through the driving channel 402. The driving member 2 is in contact with the first surface 1043 of the first intermediate fixed segment 1042. The driving member 2 applies force toward the first intermediate fixed segment 1042, so that the clamping end 102 moves toward the locking segment 103 until the clamping end 102 enters the arc-shaped opening 1033 of the locking part 1032. After the clamping end 102 is locked, the driving member 2 withdraws from the driving channel 402.

[0043] It should be noted that the clamping state in this embodiment has two working conditions: in the first working condition, no conductive wire enters the inlet channel and the middle fixed section 104 is in a free state; in the second working condition, a conductive wire enters the inlet channel and the middle fixed section 104 is also in a slightly compressed state.

[0044] The wire clamping spring and contact terminal block provided by this utility model have the following advantages: (1) Since the locking section 103 is connected to the trigger end 101, the locking section 103 is closer to the wire clamping end 102 than the trigger end 101. Even if the movement distance of the wire clamping section in the housing 4 is short, the distance between the wire clamping end 102 and the end of the conductive wire is longer. That is, the wire clamping end 102 and the housing 4 will clamp a longer length of conductive wire, which avoids the conductive wire from loosening when under force and ensures the reliability of the connection; (2) The width of the first connecting section 105 along the Y axis is smaller than the width of the locking plate 1031 and the trigger end 101, which makes it easier for the trigger end 101 to move. The arc-shaped setting of 06 makes the yield strength stronger and helps the stability during long-term use; (3) The locking part 1032 is arc-shaped, and the arc-shaped opening 1033 faces the middle fixed section 104. The lever arm formed by the locking part 1032 is shorter. Compared with the vertical setting of the locking part 1032 and the locking plate 1031, the locking force of the arc-shaped locking part 1032 is higher, which makes the locking force of the locking part 1032 on the clamping end 102 more stable and has stronger shock resistance; (4) Before the conductive wire enters the housing 4, the detection tool enters along the detection hole 403 and the detection tool contacts the contact part 1044 to determine whether the current carrier 3 is charged.

[0045] As an alternative implementation, the material of the body 1 can also be conductive materials such as silver or aluminum; the material of the current carrier 3 can also be conductive materials such as silver or aluminum.

[0046] As an alternative implementation, the number of locking parts 1032 may be one, three, four or even more.

[0047] As an alternative implementation, the contact part 1044 may not be provided on the body 1, and the body 1 may directly contact the fluid carrier 3.

[0048] As an alternative implementation, the locking section 103 may not have a locking part 1032. Instead, a slot or hole is provided on the locking plate 1031, and the wire clamping end 102 is provided with an extended end, which is then locked by the locking plate 1031 and the wire clamping end 102.

[0049] As an alternative implementation, the locking part 1032 may not be arc-shaped, and the locking part 1032 and the locking plate 1031 may be arranged perpendicularly.

[0050] 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.
