Detailed Description

The present invention is further described with reference to the following drawings and specific examples so that those skilled in the art can better understand the present invention and can practice the present invention, but the examples are not intended to limit the present invention.

The invention provides a terminal block structure 1 easy for wire insertion, which can be used for inserting and connecting a wire A, wherein the wire A is provided with a core wire A1. Referring to fig. 1 to 4, the terminal block structure mainly includes an insulating base 10, a conductive terminal 20, a turning assembly 30 and a clamping spring 40.

The insulating base 10 is made of plastic or other insulating material. The interior of which has a cavity 11. The top of the insulating base 10 is provided with a wire jack 12 and an open slot 13 which are communicated with the cavity 11, and the wire jack 12 and the open slot 13 are located on the same side of the insulating base 10 and are adjacently arranged left and right. A clamping groove 111 is further arranged in the accommodating cavity 11 of the insulating base 10, and a convex column 14 is convexly arranged at a position close to the open slot 13 and in the accommodating cavity 11.

The conductive terminals 20 are made of a material having good conductivity, such as copper or an alloy thereof. Which is fixed in the receiving cavity 11 and arranged corresponding to a lower position of the wire insertion hole 12. The conductive terminal 20 mainly includes a first conductive sheet 21 and a second conductive sheet 22 vertically bent from the first conductive sheet 21. The first conductive sheet 21 has a contact surface 211 parallel to the insertion direction of the wire a, and the core wire A1 can be attached to the contact surface 211 after the wire a is inserted. The first conductive sheet 21 further has an attaching surface 212 opposite to the contact surface 211, and is attached to the inner wall of the cavity 11, and connection pins 213 extend from the upper end and the lower end of the first conductive sheet 21, respectively, and each connection pin 213 penetrates out of the cavity 11 to the outside of the insulating base 10.

The wrench assembly 30 is made of plastic or other insulating material. The wrench mainly comprises a main body 31, a trigger 32 and a pressing part 33, wherein the trigger 32 and the pressing part 33 extend from the main body 31 at intervals and are located on the same side of the main body 31. In the embodiment, the trigger 32, the pressing portion 33 and the main body 31 are integrally formed, but the invention is not limited thereto, for example, the trigger 32 and the pressing portion 33 can be fixed on the main body 31 by a fastening or locking manner. The main body 31 has a pivot portion 311 pivoted on the protruding pillar 14 of the insulating base 10. The pivoting portion 311 and the pressing portion 33 are separately disposed, and preferably, the pivoting portion 311 is disposed between the trigger 32 and the pressing portion 33. The trigger 32 extends out of the insulating base 10 through the opening 13 and is movable along the side of the wire insertion hole 12, and the trigger assembly 30 can rotate and swing relative to the insulating base 10 about the pivot portion 311 by moving the trigger 32. In the embodiment, the protruding pillar 14 further protrudes with a pivot 141, and the pivot portion 311 is a shaft hole sleeved with the pivot 141. However, the present invention is not limited to this, for example, the protruding pillar 14 may also have a pivot hole, and the pivot portion 311 is a pivot.

The clip spring 40 may be made of a material with good conductivity, such as copper or an alloy thereof. The clamping spring 40 is disposed in the cavity 11, and mainly includes a fixed section 41, a movable section 43, and a sleeving section 42 connecting the fixed section 41 and the movable section 43. The fixed section 41 is clamped in the clamping groove 111, and the sleeve section 42 is sleeved on the convex column 14 and limited between the convex column 14 and the inner wall of the cavity 11, so that the clamp spring 40 can be fixed in the insulating base 10. The movable section 43 partially abuts against the outer periphery of the pressing portion 33 and extends to the lower side of the wire insertion hole 12 to abut against the first conductive sheet 21, and the movable section 43 is pressed by the pressing portion 33 to operatively open or close the wire insertion hole 12. In addition, the fixing section 41 is formed with a fastening slot 411, and the fastening slot 411 is used for the second conductive sheet 22 to be fastened, so as to further fix the conductive terminal 20.

Please refer to fig. 5 and fig. 6, which illustrate a schematic usage of the terminal block structure 1 according to the present invention. When the wire a is to be inserted, the trigger 32 can be rotated toward the wire insertion hole 12, so that the pressing portion 33 presses the movable section 43 of the clamp spring 40 downward to open the wire insertion hole 12, so as to insert the wire a from the wire insertion hole 12, and enable one side of the core wire A1 to be attached to the contact surface 212 of the first conductive sheet 21. Then, the trigger 32 is turned towards a direction away from the wire insertion hole 12, so that the movable section 43 of the clamping spring 40 is separated from the pressing of the pressing portion 43, and the core wire A1 is clamped together with the first conductive sheet 21 by the elastic restoring force of the movable section 43 itself. Since the actuating range of the trigger 32 is only above the insulating base 10, the working space required by the trigger 32 during the operation process can be greatly saved. In addition, because the pivoting part 31 is arranged between the trigger 32 and the pressing part 33, the pressing part 33 can be opened and closed to the maximum extent, and the wire plugging operation is convenient for personnel.

For further explanation, referring back to fig. 4, a base line x is formed on the top surface of the insulating base 10. When the trigger assembly 30 is not used, the clamp spring 40 pushes the pressing portion 33 upwards to approach the top of the cavity 11 by its own elastic force, so that the trigger 32 operates and moves above the base line. Preferably, the trigger 32 is approximately flush with the side of the insulating base 10 to obtain the maximum use space at the side of the insulating base 10 without causing objects at the side of the insulating base 10 to interfere with the trigger 32.

Referring to fig. 5, the main body 31 of the wrench assembly 30 has a long side 312, and an operating angle θ is formed between the long side 312 and the base line x. In the state of pulling the wrench assembly 30, the main body 31 in the cavity 11 can be movably close to the inner wall of the cavity 11, so that the long side 312 is parallel to the insertion direction of the wire a, and the long side 312 is perpendicular to the base line x, i.e. the working included angle θ is about 90 °.

Therefore, as can be seen from fig. 4 and 5, the rotation range of the wrench assembly 30 is such that the working angle θ is between about 90 ° and 120 °. Therefore, in the terminal block structure 1 of the present invention, the trigger 32 is operated and moved above the base line, and the working included angle θ is between 90 ° and 120 °, so as to ensure that the operation space can be saved, and the opening and closing space of the clamp spring 40 can be increased.

Referring to fig. 7 and 8, the terminal block structure 1 of the present invention further includes a cover plate 50, which covers the side edge of the insulating base 10. The insulating base 10 is further provided with a plurality of fixing posts 15, and the cover plate 50 is provided with a locking block 51 and a plurality of through holes 52. The engaging block 51 is engaged between the conductive terminal 20 and the top of the cavity 11, and the through holes 52 are respectively sleeved and fixed on the fixing posts 15, thereby fixing the cover plate 50 to the insulating base 10. Further, the terminal block structure 1 of the present invention may be stacked with another terminal block structure 1 or a plurality of terminal block structures 1 to form a terminal block assembly structure, so that a larger number of terminal block structures can be arranged within the same volume range due to the compact overall structure, thereby significantly reducing installation costs and use costs.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention.
