Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 As shown, in this example, a handle terminal block includes a housing 1, a handle 2, and a spring 3. The housing 1 is a common rectangular block shape, with an opening formed on its side that communicates with a cavity, through which the spring, handle, etc., can be installed. A socket 10 communicating with the cavity is formed on the housing 1, for example, at the end face adjacent to the face where the opening is located. The socket 10 is used for inserting wires. A conductor 4 for external electrical connection is mounted on the housing 1, with its tip inside the socket cavity. The conductor is typically chair-shaped, but other configurations can also be used.

[0030] The handle 2 is exposed outside the housing 1 and the part inside the cavity of the housing 1 is pivotally connected to the cavity wall of the housing 1. A spring 3 is installed inside the cavity of the housing 1. The spring 3 includes a contact part 32, a clamping part 33 and a bent part 31 connecting the two. The spring 3 is pivotally connected to the cavity wall of the housing 1 through the bent part 31. The clamping part 33 of the spring 3 abuts against the top of the conductor 4 to form a blockage in the socket. When the wire or the like is inserted, the clamping part of the spring 3 cooperates with the conductor to clamp the wire inserted from the socket.

[0031] This example focuses on improving the mating structure between the handle and the spring, such as... Figure 1 , Figure 3 , Figure 4 As shown, the handle 2 includes a body 21, a pressure plate 22, and a limiting plate 23. In this example, the body 21 is shown as a strip, but other configurations, such as an L-shape, can also be used. The bottom surface of the body 21 has a plate-shaped pressure plate 22 protruding outward, and the side of the pressure plate 22 has a plate-shaped limiting plate 23 protruding outward along the width direction of the body 21. The limiting plate behind the pressure plate 22 has a groove or through hole, i.e., a limiting hole 24.

[0032] The end of the abutment 32 is formed by an outwardly protruding connecting end 34. The configuration and position of the connecting end 34 can be selected according to the requirements, such as the protruding connecting end shown in this example. For the connecting end, a groove can be cut or pressed into the clamping part of the spring sheet on the market, and one side of the groove wall is the connecting end, or it can be formed integrally during the spring sheet forming process.

[0033] The connecting end 34 extends into the limiting hole 24, and the limiting hole 24 reserves a space for the movement of the connecting end. As shown in the figure, the size of the limiting hole is larger than that of the connecting end, and the elastic reset of the abutting part makes the connecting end move correspondingly, so that the connecting end can move in the limiting hole. The size of the connecting hole can be limited. When the handle is locked in the initial position by the elastic force of the abutting part, there is a gap between the connecting end 34 in the initial position and the hole wall of the limiting hole 24 above it, which avoids the connecting end 34 exerting an upward force on the hole wall of the limiting hole 24, thereby causing the stability of the handle in the initial position to deteriorate. Figure 1

[0034] As shown in the figure, when the handle 2 is turned downward to the initial position, the pressing plate 22 presses the abutting part 32 in the elastic sheet 3 to make the clamping part 33 extend into the hole cavity of the insertion hole 10, so as to limit the extension of the wire from the insertion hole, that is, to form a lock for the insertion hole; when the handle 2 is turned upward, the pressing plate 22 moves upward, the hole wall of the limiting hole 24 pushes the connecting end 34 to make the abutting part 32 move upward, and the clamping part 33 moves upward at the same time, thereby releasing the lock of the insertion hole. At this time, the position of the handle is the unlocking position. Compared with the scheme in which the handle directly drives the clamping part of the elastic sheet, the operation of the structure is more labor-saving. Figure 7

[0035] In order to reduce the size of the terminal and strengthen the structural stability, in this example, the pressing plate 22 is formed between the center point of the pivot connection of the handle 2 and the head end of the handle 2, the reinforcing plate 26 is formed at the bottom surface of the body 21 at the position behind the pressing plate 22, and the side surface of the reinforcing plate 26 is connected with the limiting plate 23. The structural stability of the limiting plate is improved by the reinforcing plate, and the selection of the position of the pressing plate helps to reduce the height of the terminal.

[0036] The gap 25 is reserved between the reinforcing plate 26 and the pressing plate 22, and the limiting hole 24 is formed at the position of the limiting plate corresponding to the gap 25. The gap is used to meet the movement requirement of the abutting part connected with the connecting end due to the elastic deformation, which helps to improve the stability of operation.

[0037] For the locking of the handle in the initial position, the elastic locking or the fixing by screws, buckles and the like is usually used. In this example, the handle is locked in the initial position by elastic force, as shown in the figure, in the initial position, the pressing plate 22 abuts against the abutting part 32, and the elastic force of the reset of the abutting part 32 is directed to the pivot center of the handle. As shown in the figure, the straight line formed by the point where the pressing plate abuts against the abutting part and the pivot center of the handle coincides with the direction of the elastic force of the reset of the abutting part (the line shown in F in the figure), or the direction of the elastic force of the reset of the abutting part is downwardly deviated compared with the straight line. In this structure, the handle can be locked by the elastic force of the reset of the abutting part. Figure 1 Figure 7 Figure 7

[0038] ​​​​​To improve the stability of the handle in the initial position, the abutting part 32 in this case includes a slope section 321 and an upward section 322. The slope section 321 is connected to the curved part 31 at one side of the slope section 321 and connected to the low end of the upward section 322 at the other side of the slope section 321. The end of the upward section 322 is formed with a connecting end 34. When the handle is turned down to the initial position, the end of the pressing plate 22 of the handle abuts against the slope section 321 of the upward section 322. The slope section 321 can further limit the upward turning of the handle. When the handle 2 is turned up to the unlocking position, the end of the pressing plate 22 passes the top end of the slope section 321. The limiting hole 24 pushes the abutting part 32 to move upward and simultaneously releases the locking of the insertion hole 10 by the clamping part 33 of the elastic sheet.

[0039] To improve the structural stability of the connecting end, the connecting end 34 and the abutting part 32 connected thereto can be bent at the end side of the handle in the length direction, as shown in the upward bending in Figure 5 .

[0040] To improve the stability of the handle in the unlocking position, as shown in Figure 1 , Figure 3 , Figure 7 , the end of the limiting plate 23 is formed with a protrusion 27, such as a circular arc, a rectangle, a triangle, etc. The housing 1 is formed with a stopper 13 on the cavity wall to cooperate with the protrusion 27. The stopper 13 is in the moving path of the protrusion 27. When the handle 2 is in the unlocking position, the protrusion 27 deforms elastically to pass the stopper 13. The stopper limits the resetting of the handle by limiting the protrusion. The shape of the stopper can be selected according to the requirement. As shown in Figure 1 , an arc-shaped installation groove is formed on the left cavity wall of the housing 1. The protrusion 27 of the elastic sheet is installed in the installation groove and sleeved on the second protrusion 11. The stopper 13 is formed on the cavity wall adjacent to the installation groove, as shown in Figure 1 , Figure 7 .

[0041] To facilitate the installation of the handle, the housing 1 is formed with a first protrusion 12 on the cavity wall. The tail end of the handle in the cavity of the housing is formed with a pivoting hole. The first protrusion 12 extends into the pivoting hole to be pivotally connected. The head end of the handle 2 extends out of the cavity wall of the housing.

[0042] As shown in Figure 6 , the side of the housing is open. Multiple housings are arranged side by side to seal the side openings of the adjacent housings. The side openings of the housings on the side are sealed by the cover plates. Alternatively, a single housing is applied. The side opening of the housing 1 is sealed by the cover plate 5, as shown in Figure 2 .

[0043] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical scheme falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application are also considered to be within the protection scope of the present application.
