Description

Technical Field

[0001] The present invention relates to the technical field of power connection devices, and in particular to a trigger locking type connection terminal. Background Art

[0002] With traditional plug-in spring terminals, a conductor is inserted into a socket and engages the clamping legs of a spring clip. The legs directly act on the conductor, mechanically locking it and establishing electrical contact with the busbar. However, during insertion and locking, the conductor must overcome the spring force of the legs to secure it in place. This not only requires significant insertion force but can easily damage the conductor or cause it to be improperly installed. Furthermore, it also cannot directly accommodate stripped, multi-strand flexible conductors, requiring improvement. Summary of the Invention

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] The present application document discloses a trigger locking type terminal, comprising a housing and a bus bar, a clamping spring, and an operating member arranged on the housing. The housing is provided with a socket for inserting a wire, the clamping spring is provided with a connected retaining leg and a clamping leg, the operating member is slidably connected to the housing and pushes the clamping leg from a clamping position to an open position by moving the operating member. When the clamping position is in the clamping position, the clamping leg cooperates with the bus bar to clamp the wire inserted from the socket and when the position is in the open position, space is made available for the wire to be inserted from the socket. A release member is pivotally connected in the housing, and the release member has a connecting portion and the connecting portion is connected to the The hooking parts in the operating member intersect on the moving path to hook and cooperate with each other, and at least a part of the release member is located on the moving path of the clamping leg. When the operating member pushes the clamping leg to the open position, the clamping leg synchronously pushes the release member to rotate so that the connecting part moves to the locked position. When moving to the locked position, the connecting part is hooked with the hooking part in the operating member to lock the operating member, and when the release member is in the locked position, at least a part of it is located on the path of the wire insertion in the jack cavity, so that the wire inserted from the jack pushes the release member to rotate to release the hooking part and the clamping leg is reset to the clamping position accordingly.

[0005] When in use, if the operating part is moved downward by force, the clamping leg is pushed to the open position, and the clamping leg is simultaneously pushed by the clamping leg to make its connecting part hooked with the hooking part in the operating part to lock the operating part, and the clamping leg is simultaneously locked so that the clamping leg cannot be reset. At this time, the wire can be easily inserted into the socket. During the wire insertion process, the release part is pushed to rotate to release the hooking lock with the hooking part, and the clamping leg is reset to the clamping position to cooperate with the busbar to clamp the inserted wire, making the wire plugging and unplugging operation more convenient.

[0006] Furthermore, when the clamping leg pushes the release member to move to the locked position, the connecting portion in the release member first reaches the moving path of the hooking portion, and the hooking portion in the operating member abuts and passes over the connecting portion, and the two are hooked. It is limited that the connecting portion reaches the moving path of the hooking portion first. When the hooking portion abuts against the connecting portion, it is caused to rotate to pass over. The connecting portion continues to rotate forward under the push of the clamping leg to hook with the hooking portion. The hooking locking is more stable. Of course, the hooking portion can also be deformed or the operating member connected to the hooking portion can be elastically deformed to pass over the connecting portion, and then the two are hooked to lock the operating member. It can be selected according to needs.

[0007] Furthermore, at least a portion of the release member is located on the path when the clamping leg is reset to the clamping position, and when the clamping leg is reset to the clamping position, the release member is synchronously pushed to rotate to the initial position. The reset is pushed by the clamping leg, and the coordination stability between the operating member and the release member is improved.

[0008] Furthermore, a groove is provided on the top surface of the main body, and part of the clamping leg is located in the groove. When the clamping leg is reset to the clamping position, the release member is synchronously pushed to rotate to the initial position. The groove wall is on the path of the clamping leg reset. When the clamping leg is reset, the clamping leg pushes the release member to reset, which facilitates and stabilizes the next wire insertion, etc.

[0009] As for the release member, its specific configuration can be selected according to needs, and the following configuration is preferably adopted:

[0010] Furthermore, the release member includes a main body, a push block 1, a push block 2 and a connecting portion, the connecting portion is protruding from the front end of the main body, the push block 1 and the push block 2 are protruding from the side of the main body, the push block 1 is located on the moving path of the clamping leg, and the clamping leg pushes the push block 1 to move the release member from the initial position to the locking position. When the release member is in the locking position, the push block 2 is located on the path for inserting the wire into the jack cavity.

[0011] The configuration of the main body is a common plate body, of course, a column or other configuration can also be adopted according to needs, with the push blocks 1 and 2 protruding from the side matching with the clamping legs and the wires, and the connecting part protruding from the front end matching with the hooking part at the operating part. The structural design is reasonable and convenient for layout and installation.

[0012] For the body, the body may be pivotally connected to the housing cavity wall, or the body may be pivotally connected to the bus bar. Of course, one side of the body may be pivotally connected to the housing and the other side may be pivotally connected to the bus bar.

[0013] Preferably, a pivot portion is provided on the side of the main body, which is pivotally connected to the shell cavity wall and the bus bar through the pivot portion. The pivot portion is located below the push block 1. For the pivot portion, a hole or groove is formed on the side of the main body, such as an outwardly protruding shaft body or a body to form a pivot connection with the shaft body protruding from the shell cavity wall or the bus bar.

[0014] Furthermore, the busbar includes a horizontal portion and a longitudinal portion, the longitudinal portion is in the cavity of the jack, a protrusion is provided on the horizontal portion, and the protrusion forms a pivot connection with the pivot portion on the side of the body, limiting the busbar configuration to facilitate connection with the release member.

[0015] Furthermore, the longitudinal portion is arranged at the head end of the horizontal portion and a connecting block is arranged at the tail end of the horizontal portion, and the connecting block is connected to the retaining legs in the clamping spring to improve the stability of the structure.

[0016] Furthermore, the operating member is slidably connected to the mounting hole provided on the shell, and the operating member includes a main body, a hooking portion, and a push block three. The hooking portion is provided at the tail end of the main body, and the push block three is provided to protrude outward from the side of the main body. The clamping leg is on the downward movement path of the push block three. When the operating member moves downward relative to the shell, the push block three pushes the clamping leg to the open position, which limits the layout position of the hooking portion and the push block three, and facilitates stable cooperation with the clamping leg, the connecting portion, etc.

[0017] Furthermore, a stop block is set on the main body of the operating member or the push block and a limit block is set on the corresponding mounting hole wall. The limit block is on the path of the stop block moving upward to limit the operating member from being separated from the mounting hole. The limit block cooperates with the stop block to limit the operating member from being separated from the mounting hole, thereby improving stability.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention features a newly designed terminal block structure. When the operating member pushes the clamping leg, the clamping leg simultaneously pushes the release member to rotate. This causes the connecting portion in the release member to hook with the hooking portion on the operating member to lock the operating member, which in turn locks the clamping leg. When a wire is inserted from the jack, the wire pushes the release member to rotate, releasing the lock from the hooking portion. The clamping leg returns to its original position to clamp the wire, making wire insertion and installation more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figure 1-Figure 4As shown in this example, a trigger locking type terminal comprises a housing 1 and a bus bar 5, a clamping spring 3, and an operating member 2 mounted on the housing 1. The housing is formed of an insulating material, such as a rectangular box. The clamping spring 3 and the bus bar 5 are mounted in the housing 1. The clamping spring 3 has a retaining leg 32 and a clamping leg 31. The retaining leg and the clamping leg are connected at the end to form a U-shape as a whole. A socket 10 for inserting a wire is formed at the end face of the shell 1, and a mounting hole 12 is formed at the same end face or an adjacent or opposite end face. In this example, the mounting hole 12 is formed at the same end face, and the operating member 2 is slidably connected to the mounting hole 12. When in use, the operating member is pressed down, and the operating member pushes the clamping leg from the clamping position to the open position during the downward movement. When the clamping leg is in the clamping position, the clamping leg cooperates with the bus bar to clamp the wire inserted from the socket. When in the open position, the clamping leg moves away from the socket cavity to make room for the wire to be inserted from the socket. The above is a common matching structure of the terminal block and will not be repeated here.

[0035] like Figure 1-Figure 4 As shown, in this embodiment, the housing 1 is pivotally connected to a release member 4. The release member 4 has a connecting portion 41, and the operating member 2 has a hooking portion 24. The connecting portion 41 intersects with the hooking portion 24 of the operating member 2 along their travel path to form a hooked engagement. At least a portion of the release member 4 is located in the travel path of the clamping leg 31. The engagement relationship is as follows: when force is applied to move the operating member 2 downward, the operating member 2 pushes the clamping leg 31 to the open position. The clamping leg 31 simultaneously pushes the release member 4 to rotate, causing the connecting portion 41 to move to the locked position. When moving to the locked position, the connecting portion 41 hooks with the hooking portion 24 of the operating member 2 to lock the operating member (i.e., restrict its upward movement and reset). In the locked position, the release member 4 is at least partially located in the path of the wire inserted into the jack cavity. The wire inserted into the jack pushes the release member to rotate, releasing the hooking portion from the connecting portion. The clamping leg correspondingly returns to the clamped position, and the clamping leg simultaneously pushes the operating member upward and reset.

[0036] Regarding the connection between the connecting portion and the hooking portion, if the hooking portion in the operating member reaches and passes the locking position, and then the connecting portion reaches the locking position, when the clamping leg pushes the operating member upward, the hooking portion hooks with the connecting portion on the upward movement path, thereby restricting the upward movement of the operating member and simultaneously locking the clamping leg in its position. Alternatively, the connecting portion reaches the locking position first, and the hooking portion subsequently abuts the connecting portion at the locking position, and the hooking portion presses the connecting portion downward, causing the release member to continue to rotate until the hooking portion passes the connecting portion, and the two are hooked.

[0037] As for the hooking structure between the connecting portion and the hooking portion, that is, the hooking structure in the conventional sense, such as the hooking formed by the projection extending into the groove, or the hooking between the two hooks, or the hooking between the hook and the groove, or the hooking between the hook and the protrusion. Figure 5In the configuration shown, the release member 4 includes a body 40, a push block 1 42, a push block 2 43, and a connecting portion 41. The body is in the form of a common plate, and the push blocks 1 42 and 43 are formed to protrude from the side of the body 40. The configuration of the push blocks 1 and 2 can be selected according to needs and is not limited thereto. The push block 1 42 is located in the movement path of the clamping leg 31, and the clamping leg 31 pushes the push block 1 42 to move the release member 4 from the initial position to the locked position. When the release member 4 is in the locked position, the push block 2 43 is located in the path for inserting the wire into the jack cavity. As for the connecting portion, the connecting portion 41 can be formed to protrude from the front end top surface of the body 40, such as a protruding bump as the connecting portion. The configuration of the bump can be selected according to needs. The connecting portion can be selected to be connected to the push block 1 42 as a whole, or the connecting portion can be formed to protrude from the side of the front end of the body. Similarly, the connecting portion can be selected to be connected to the push block 1 as a whole. In addition, when the wire needs to be pulled out, the operating part can also be moved down, and the release part can push the wire out through the second push block when it is rotated, making it more convenient to pull out the wire.

[0038] To facilitate the installation of the release member, in this example, a pivoting portion 44 is formed on the side of the body 40 of the release member 4. The pivoting portion is in the shape of a shaft or a pivot hole, such as a shaft protruding from the housing that extends into the pivot hole to form a pivot connection. In this example, the pivoting portion 44 is illustrated as an example of a protruding shaft configuration, such as the tail end of the pivoting portion 44 extending into the pivot hole on the housing 1 to form a pivot connection, or the shaft on the housing extends into the tail end hole of the pivoting portion to form a pivot connection. In addition, a protrusion 54 can be formed on the horizontal portion of the bus bar 5 to pivotally connect with the pivoting portion 44, such as Figure 3 、 Figure 4 As shown, the busbar 5 includes a horizontal portion 52 and a longitudinal portion 51. The longitudinal portion 51 is located in the cavity of the insertion hole. A protrusion 54 is formed on the horizontal portion 52. The end of the pivot portion 44 extends into the pivot hole formed at the protrusion 54 to form a pivot connection, which helps to improve the connection stability of the release member. Alternatively, a shaft is formed on the protrusion 54 to extend into the hole formed at the end of the pivot portion to form a pivot connection. In addition, it is also possible to Figure 9 As shown, the bottom surface of the push block 1 is extended downward to be connected to the lower pivot portion as a whole, and the end of the push block is extended toward the side of the push block 2 to be connected as a whole. This structure helps to improve stability.

[0039] In addition, a connecting block 53 can be added to connect with the retaining leg 32 in the clamping spring, such as the longitudinal portion 51 is at the head end of the horizontal portion 52 and the connecting block 53 is formed longitudinally at the tail end of the horizontal portion 52. The connecting block 53 is connected to the retaining leg 32 in the clamping spring, such as by plugging, snapping, etc., which helps to improve the stability of the structure.

[0040] In order to form a hooking fit with the connecting portion, in this example, a groove or hook body is formed at the corresponding position of the operating member 2, and the groove or hook body is used as the hooking portion 24, and the connecting portion 41 is extended into the groove to form a hook, or the connecting portion 41 is hooked with the hook body of the operating member 2. Figure 6 In the illustrated configuration, the operating member 2 comprises a rod-shaped main body 21 with a push block 3 22 formed protruding from the side of the main body 21. The clamping leg 31 is located in the downward movement path of the push block 3 22. When the operating member moves downward, the push block 3 presses the clamping leg to move it. The configuration of the push block 3 can also be selected according to needs.

[0041] In order to limit the operating member from being separated from the mounting hole, a stopper 23 may be formed on the main body of the operating member or the push block 3, such as Figure 6 As shown, the main body of the operating member and the push block are formed with blocks 23 at three corresponding positions, and the corresponding limit block 11 is formed at the wall of the mounting hole 12. The limit block is on the path of the block moving upward to limit the operating member from separating from the mounting hole.

[0042] In order to improve the stability of the cooperation between the release member and the operating member, at least part of the release member 4 can be placed on the path when the clamping leg 31 is reset to the clamping position. When the clamping leg 31 is reset to the clamping position, the release member is synchronously pushed to rotate back to the initial position and reset by the clamping leg. Figure 7 As shown, it includes a sheet 310 and a protruding end 311 protruding from the side of the sheet. A groove 45 is formed on the top surface of the main body 40 of the release member. The protruding end 311 of the clamping leg is located in the groove 45. The groove wall is located in the path for the protruding end to return to the clamping position. When the clamping leg returns to the clamping position, it simultaneously pushes the release member to rotate back to the initial position. Of course, a protruding column can also be formed on the top surface of the main body of the release member so that the protruding column is located in the moving path of the protruding end of the clamping leg. In addition, the clamping leg can be directly widened so that the side of the clamping leg is located in the groove of the release member body, or the side of the clamping leg is located in the moving path of the protruding end on the release member body, depending on the needs. A torsion spring for rotational reset can also be added to the pivot joint of the release member to promote the release member to rotate and reset.

[0043] Of course, the structure in which the release member pushes the release member to reset can also be omitted according to needs (such as Figure 7 The convex end is omitted), the clamping spring adopts Figure 8 The common configuration shown is sufficient.

[0044] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
