The invention discloses a current secondary loop terminal element, which comprises an element body, a current connecting sheet 6 and a slot 12, and particularly further comprises an error-proof lock. The function of the anti-false lock is to be able to lock the current connection piece 6. The short-circuit plug 9 comprises an unlocking piece, and after the plug of the short-circuit plug 9 is inserted into the slot 12, the unlocking piece on the short-circuit plug 9 can unlock the anti-misoperation lock, so that the locking of the current connecting piece 6 can be released, and at the moment, the current connecting piece 6 can be moved. If the short-circuit plug 9 is not inserted into the slot 12, the current connection piece 6 cannot be slid out because the current connection piece 6 is locked by the false lock. Thus, the problem of sliding out the current connection piece 6 when the short-circuit plug 9 is not inserted can be avoided, and the current secondary circuit opening can be effectively avoided.
If the current secondary circuit is to be withdrawn, firstly, the short circuit plug 9 needs to be inserted into the slot 12, after the short circuit plug 9 is inserted, the error-preventing lock can be unlocked, the pressing force on the current connecting sheet 6 can be relieved, and then the current connecting sheet 6 can be slid out, so that the withdrawal of the current secondary circuit is realized.
Next, introduce the concrete structure of mistake proofing lock, mistake proofing tool to lock body includes: a lock 1, a torsion spring 5 and a receiving portion. One end of the lock 1 is hinged to the element body, which end is the hinged end. The end of the locking element 1 opposite to the hinged end is the locking end. The torsion spring 5 is arranged at the hinged end, and the torsion force of the torsion spring 5 forces the locking end of the lock 1 to press the current connecting piece 6, so that the locking of the current connecting piece 6 is formed, as shown in fig. 1 and 2. The abutting portion is arranged on one side of the lock piece 1 and is arranged close to the hinge ends of the slot 12 and the lock piece 1. The abutting part is provided with an abutting surface 2, and an unlocking piece of the short circuit plug 9 is matched with the abutting surface 2. During insertion of the plug into the socket 12, the unlocking member will act on the abutment surface 2 forcing the locking end of the locking member 1 to tilt, thus releasing the locking of the current connection piece 6, as shown in fig. 3 and 4.
In a specific embodiment of the present invention, the abutment surface 2 in the abutment portion is sloping, and correspondingly, the unlocking member is a wedge block 4, and the wedge surface of the wedge block 4 is matched with the abutment surface 2. During the process of inserting the plug of the short circuit plug 9 into the slot 12, the wedge-shaped block 4 can slide along the abutting surface 2, the wedge-shaped block 4 can transmit a rotating force to the lock piece 1, and the lock piece 1 is forced to rotate and tilt, so that unlocking is realized.
It should be noted that, the abutment surface 2 may be an arc-like surface, and the shape of the abutment surface 2 is not limited herein, so long as it can ensure that the unlocking member is transferred to the locking member 1 through the abutment surface 2 by a continuous rotation force, so that the locking member 1 is tilted up and falls into the protection scope herein.
Referring to fig. 1, 2 and 3, in order to ensure that the unlocking member can accurately abut along the abutting surface 2, the present invention provides a stopper 3, wherein the stopper 3 is disposed opposite to the abutting surface 2 and forms an inlet with the wedge surface. The wedge block 4 is provided with an adapter block 10, which adapter block 10 can be brought into the inlet exactly. And when the adapter block 10 of the wedge block 4 enters the inlet, the wedge surface of the wedge block 4 just forms a fit with the abutting surface 2.
It should be noted that if it is to be ensured that the plug can be inserted into the slot 12, it is necessary to make the adapter block 10 enter the inlet and ensure that the wedge block 4 slides along the abutment surface 2, otherwise, the abutment portion of the false lock will interfere with the short circuit plug 9, preventing the insertion of the plug.
With continued reference to fig. 1, 2 and 3, an outlet 11 is formed between the stopper 3 and the locking member 1, and the outlet 11 is configured to allow the adapter block 10 to be removed. The angle between the outlet 11 and the inlet is close to 90. In the starting position, the inlet is facing upwards and the outlet 11 is on the side. The adapter block 10 enters the inlet, the wedge block 4 slides along the abutment surface 2, the lock 1 will rotate approximately 90 °, and the outlet 11 is then facing upwards, the inlet being turned sideways. If it is necessary to restore the secondary current circuit, the shorting plug 9 is pulled out of the slot 12 and the adapter block 10 of the wedge block 4 is removed through the outlet 11.
Before the short-circuit plug 9 is pulled out, the current connection piece 6 needs to be reset first, so that the first current deflector 8 and the second current deflector 7 are conducted.
In order to ensure the smoothness of the movement of the adapting block 10 between the inlet and the outlet 11, the invention rounds the part of the limiting block 3 at the inlet to form an inlet round corner, and rounds the part of the limiting block 3 at the outlet 11 to form an outlet 11 round corner.
In order to ensure that the locking element 1 provides an effective pressing force on the current connection piece 6, the locking end of the locking element 1 is provided in the form of a hook.
As can be seen from the above description, the anti-false lock mainly includes a lock 1 and a propping portion, where the propping portion includes a propping surface 2 and a limiting block 3. The invention preferentially adopts the injection molding processing technology to manufacture the false lock, and integrally forms the false lock.
In addition, a plurality of false locks arranged side by side are provided on the element body, and correspondingly, the shorting plug 9 includes a plurality of unlocking pieces arranged side by side. For example, in the case of four-core wiring, four anti-misoperation locks are required to be arranged on the element body, and four unlocking pieces are required to be arranged on the short circuit plug 9, as shown in fig. 4.
In summary, the use process of the current secondary loop terminal element is as follows: if the secondary current circuit is to be withdrawn, the plug of the shorting plug 9 is first inserted into the slot of the slot 12, the adapter block 10 is then inserted into the inlet of the abutment, and then the plug is inserted into the slot 12, and at the same time the wedge block 4 acts on the abutment surface 2, thereby rotating the locking element 1 and unlocking the current connection piece 6. The current connection piece 6 can then be slid out and withdrawn from the current secondary circuit. When the secondary current circuit needs to be restored, the current connecting piece 6 is reset, the first guide vane 8 and the second guide vane 7 are conducted, the short circuit plug 9 is pulled out upwards, the plug is moved out of the slot 12, the adapter block 10 is moved out of the outlet 11 of the abutting part, and the locking piece 1 compresses the current connecting piece 6 again under the action of the torsion spring 5.
