Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a trigger-type wiring terminal. Background Art

[0002] Currently, trigger-type terminal blocks typically include an independent clamping spring, a retaining element, and an operating element. A locking portion maintains the clamping spring in its initial locked state. When a wire is inserted into the terminal block, the trigger portion of the retaining element is pressed downward, causing the trigger portion to deflect and release the locking portion, thereby releasing the clamping legs of the clamping spring and placing them in a clamped state. The operating element switches the clamping state to a locked state to allow the wire to be removed. This has the following drawbacks:

[0003] 1. The independent clamping spring and retaining element need to be installed separately during installation and can be set to the initial locking state after installation. To set it to the locking state, the clamping leg needs to be manually moved, but the internal space for installation is limited, and tools are usually required for operation, or the operating part is pressed by a tool, which causes problems such as inconvenient installation and low assembly efficiency.

[0004] 2. When the clamping legs of existing terminal blocks are in the clamping state, it is impossible to intuitively see whether the wire is clamped; at the same time, in order to switch the clamping legs from the clamping state to the locked state, a tool is required to operate the operating member, which can easily poke the user's hand and cause injury to the user.

At this time, under the action of the clamping leg, one end of the operating member protrudes outward from the insulating shell to form an operating portion.

[0009] Furthermore, the spring element includes a first spring bow, a second spring bow, a contact leg connected between the two spring bows, the clamping leg connected to one end of the first spring bow, and the trigger portion connected to one end of the second spring bow.

[0010] Furthermore, the first locking portion is formed by bending the main body of the clamping leg downward.

[0011] Furthermore, the second locking portion is located between the trigger portion and the second spring bow.

[0012] Furthermore, the protrusion includes a first connecting arm vertically connected to the trigger part, a locking arm horizontally connected to the trigger part and connected to the first connecting arm, and a second connecting arm connected to the locking arm and the second spring bow at a certain inclined angle relative to the trigger part; the groove is set on the locking arm.

[0013] Furthermore, two protruding columns are provided on the insulating shell, respectively used to support the first spring bow and the second spring bow.

[0028] Example

[0029] Combine Figures 1 to 6 As shown, this embodiment provides a trigger-type terminal block, comprising an insulating housing 1, a spring element 2 and an operating member 5 disposed on the insulating housing. The spring element 2 comprises a second locking portion 11, a trigger portion 9, and a resilient clamping leg 6. The spring element 2 is a one-piece component with two ends. The clamping leg 6 is located on one end of the spring element 2 and has a first locking portion 10 that cooperates with the second locking portion 11. The second locking portion 11 is an upwardly protruding portion of the spring element 2 located inside the trigger portion 9 and is provided with a slot 20 for engaging the first locking portion 10.

[0030] The clamping leg 6 can be switched between an open state and a clamping state; in the open state, the first locking portion 10 and the second locking portion 11 are engaged with each other; when the wire 4 is inserted and acts on the trigger portion 9, the first locking portion 10 and the second locking portion 11 are disengaged from each other, causing the clamping leg 6 to clamp the wire 4. At this time, under the action of the clamping leg, one end of the operating member 5 protrudes outward from the insulating shell to form the operating portion 12.

[0031] By using the integrated spring element 2 at both ends, the clamping leg 6 can be set to the open state before installation, and then the assembly can be completed with just one installation, which is convenient and quick, greatly improving the assembly efficiency, and even realizing automated assembly; at the same time, when the clamping leg 6 is released and is in the clamping state, the operating member 5 protrudes outward with an operating portion 12 with a certain height, which allows the user to more intuitively see whether the wire 4 is in the clamped state, and by pressing the operating portion 12 with bare hands, the clamping leg 6 can be switched from the clamping state to the open state, thereby pulling out the wire 4, without the need to use tools, avoiding the situation where the user's hand is injured by pressing with tools, causing injury to the user.

[0032] Specifically, in this embodiment, Figures 2 to 5 As shown, the main body of the clamping leg 6 is bent downward to form a first locking portion 10. Furthermore, the rear section of the trigger portion 9 is provided with a second locking portion 11 that protrudes upward and is compatible with the first locking portion 10. The spring element 2 includes a first spring bow 7, a second spring bow 8, a contact leg 13 connected between the two spring bows, the clamping leg 6 connected to one end of the first spring bow 7, and the second locking portion 11 connected to one end of the second spring bow 8. Specifically, the second locking portion 11 is an upward protrusion formed on the main body of the spring element 2 located inside the trigger portion 9. The protrusion includes a first connecting arm 21 vertically connected to the trigger portion 9, a locking arm 22 horizontally connected to the trigger portion 9 and connected to the first connecting arm 21, and a second connecting arm 23 inclined relative to the trigger portion 9 and connected to the locking arm 22 and the second spring bow 8. In this embodiment, the angle between the second connecting arm 23 and the trigger portion 9 is 55 degrees, and the notch 20 is provided in the middle of the locking arm 22. This protrusion significantly shortens the distance the operating member 5 has to press down on the clamping leg 6 when the operating member 5 presses down on the second locking portion 11 and the first locking portion 10 to engage.

[0033] The insulating housing 1 is provided with a first protruding column 14 and a second protruding column 15 for supporting the first spring bow 7 and the second spring bow 8 respectively, so as to facilitate direct installation of the spring element 2 .

Figure 2 As shown, on the left side, when the clamping leg 6 is in the clamping state after the wire 4 is inserted, one end of the operating member 5 protrudes outward from the insulating shell 1 to form an operating portion 12, which allows the user to more intuitively see whether the wire 4 is in the clamped state, and by pressing the operating portion 12 with bare hands, the clamping leg 6 can be switched from the clamping state to the open state, thereby pulling out the wire 4; on the right side, the clamping leg 6 is in the open state, and the operating member 5 is placed in the insulating shell 1, so that the user can clearly know the status of the clamping leg 6.

[0035] The insulating housing 1 has a locking foot 18, which is provided with a locking groove 19. The locking groove 19 allows the insulating housing 1 to be slidably locked to the support rail. It should also be noted that the insulating housing 1 in this embodiment has a removable outer wall on one side. Removal of the outer wall exposes internal components such as the spring element 2 and the operating member 5. The above are merely preferred embodiments of the present invention.
