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] At present, the trigger type terminal usually includes a clamping spring and a retaining element, which maintains the clamping spring in an initial locking state through a locking portion; when the wire is inserted into the terminal, the trigger portion of the retaining element is pressed down to deflect the trigger portion and release the locking portion, thereby releasing the clamping leg of the clamping spring and putting it in a clamping state of clamping the wire.

[0003] In the above triggering method, there must be a certain amount of space under the trigger part to ensure the normal deflection of the trigger part. Therefore, in the case of bumps during transportation or accidental dropping by the user during use, the trigger part may be triggered and the clamping legs may be in a clamped state, making it difficult to insert the wire during subsequent use. Utility Model Content

[0004] In view of this, an object of the present invention is to provide a trigger type terminal block to solve the above-mentioned problem.

[0005] The utility model adopts the following scheme:

[0006] The present application provides a retaining element including a trigger portion and a first locking portion, and a clamping spring including a clamping leg and a second locking portion, wherein the clamping leg can be switched between an open state and a clamping state; when the clamping leg is in an open state, the first locking portion and the second locking portion are clamped to each other; an elastic member is arranged under the trigger portion; when a wire is inserted and acts on the trigger portion to overcome the force of the elastic member, the trigger portion is triggered, thereby causing the first locking portion and the second locking portion to disengage from each other and causing the clamping leg to clamp the wire to be in a clamping state.

[0007] Furthermore, the elastic member and the retaining element are integral.

[0008] Furthermore, the elastic member is formed by bending a main body portion of the triggering portion of the retaining element.

[0009] Furthermore, an operating member is included, which is used to act on the clamping leg to put it in an open state.

[0010] Furthermore, when the clamping leg is in the clamping state, one end of the operating member protrudes outward to form an operating portion, and when the operating portion is pressed, its stroke is sufficient to switch the clamping leg from the clamping state to the open state.

[0011] Furthermore, the retaining element is rotatably disposed in the insulating housing; the trigger portion and the section where the first locking portion is located are disposed at a certain angle.

[0012] Furthermore, the clamping spring comprises a contact leg, a spring bow and the clamping leg; and the clamping leg is provided with a second locking portion adapted to the first locking portion.

[0013] Furthermore, the housing is provided with a first protruding column for supporting the retaining element to rotate, and a second protruding column for supporting the spring bow.

[0014] Furthermore, a busbar is arranged in the insulating shell, and first guide parts are arranged at both ends of the busbar, which are in contact and connected with the wire when the clamping legs are in the clamping state; a second guide part is also arranged on the busbar, and the abutting legs are connected to the second guide part.

[0015] Furthermore, the elastic member is placed on the bus bar and abuts against the bus bar.

[0016] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0017] The present application provides a trigger-type terminal block, in which an elastic member is arranged below the trigger portion, so that the trigger portion needs to overcome the elastic force of the elastic member in order to deflect, thereby unlocking the locking portion and releasing the clamping legs to be in a clamped state, thereby greatly reducing the situation in which the trigger portion is triggered by gravity and the clamping legs are in a clamped state in the event of bumps during actual transportation or accidental dropping by the user during use, thereby avoiding the problem of difficult wire insertion during subsequent use.

[0030] An elastic member 15 is provided below the trigger portion 13, so that the trigger portion 13 needs to overcome the elastic force of the elastic member 15 in order to deflect, thereby unlocking the locking portion and releasing the clamping leg 12 to be in a clamped state, which greatly reduces the situation in which the trigger portion is triggered by gravity and the clamping leg 12 is in a clamped state in the event of bumps during actual transportation or accidental dropping by the user during use, thereby avoiding the problem of difficulty in inserting the wire 19 during subsequent use.

[0031] Specifically, in this embodiment, Figure 2-Figure 6 As shown, the holding element 2 is rotatably arranged in the insulating housing 5; its triggering portion 13 and the locking section 9 where the first locking portion 7 is located are arranged at a certain angle; a rotating portion 16 is arranged between the triggering portion 13 and the locking section 9 where the first locking portion 7 is located. The clamping spring 1 includes a resting leg 10, a spring bow 11 and the clamping leg 12; the clamping leg 12 is provided with a second locking portion 8 adapted to the first locking portion 7. The housing is provided with a first protruding column 3 and a second protruding column 4, the rotating portion 16 is sleeved on the first protruding column 3, and the second protruding column 4 is used to support the spring bow 11. The resting leg 10 abuts against the side wall in the housing. The first locking portion 7 is formed by stamping and / or bending part of the clamping leg 12 body; the second locking portion 8 and the rotating portion 16 are formed by stamping and / or bending part of the locking section 9 body. The elastic member 15 and the holding element 2 are integral. Furthermore, the elastic member 15 is formed by bending a portion of the trigger portion 13 of the retaining element 2 .

[0032] In this embodiment, the trigger-type terminal block is symmetrically provided with a clamping spring 1 and a retaining element 2 which are independent of each other on its left and right sides. Figure 2 and Figure 7As shown, a busbar 6 is provided in the insulating housing 5, which is used to conduct the wires 19 plugged in on the left and right sides, and a first guide portion 14 is provided at both ends thereof, which is in contact and connected with the wire 19 when the clamping leg 12 is in the clamping state; a second guide portion 17 is also provided on the busbar 6, and the abutting leg 10 is connected to the second guide portion 17. Specifically, the first guide portion 14 and the second guide portion 17 are both formed by bending a part of the busbar 6 body.

The elastic member 15 is placed on the busbar 6 and abuts against the busbar 6; the above realizes the connection and conduction of the wire 19 at three contacts.

[0033] Furthermore, if Figure 1 and Figure 2 As shown, an operating member 18 is also included, which is used to act on the clamping leg 12 to put it in an open state. When the clamping leg 12 is in the clamping state, one end of the operating member 18 protrudes outward to form an operating portion, and the stroke of the operating portion is sufficient to switch the clamping leg 12 from the clamping state to the open state. The setting of the protruding portion allows the user to more intuitively see whether the wire 19 is in a clamped state. At the same time, the protruding portion has a sufficient stroke so that the user can switch the clamping leg 12 from the clamping state to the open state by pressing it by hand without tools, so as to facilitate the removal of the wire 19.

[0034] The insulating housing 5 has a locking foot 21, and the locking foot 21 is provided with a locking groove 22, and the housing can be slidably locked on the support track by means of the locking groove 22.
