Detailed ways

The invention discloses a current secondary circuit terminal component, which can avoid open circuit.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without any creative work fall within the scope of protection of the present invention.

The invention discloses a current secondary circuit terminal component, which includes a component body, a current connecting piece 6, a slot 12, and in particular, an anti-mislocking component. The function of preventing mislocking is to lock the current connecting piece 6 tightly. The short-circuit plug 9 includes an unlocking piece. After the plug of the short-circuit plug 9 is inserted into the slot 12, the unlocking piece on the short-circuit plug 9 will unlock to prevent accidental locking, and then the locking of the current connecting piece 6 will be released. At this time, The current connecting piece 6 can be moved. If the short-circuit plug 9 is not inserted into the slot 12, the current connecting piece 6 cannot be slid out because the current connecting piece 6 is locked against accidental locking. In this way, the problem of the current connecting piece 6 sliding out when the short-circuit plug 9 is not inserted can be avoided, thereby effectively avoiding the opening of the secondary circuit of the current.

If you want to exit the current secondary circuit, you first need to insert the short-circuit plug 9 into the slot 12. Only after inserting the short-circuit plug 9 can the anti-accidental locking be unlocked and the pressing force on the current connecting piece 6 be released. Then connect When it comes down, the current connecting piece 6 can be slid out, thereby realizing the withdrawal of the current secondary circuit.

Next, the specific structure of the anti-accidental locking is introduced. The anti-accidental locking includes: the lock piece 1, the torsion spring 5 and the resisting part. One end of the lock 1 is hinged on the component body, and this end is the hinge end. The end of the lock piece 1 opposite to the hinge end is the lock end. The torsion spring 5 is arranged at the hinge end, and the torsion force of the torsion spring 5 forces the lock end of the lock 1 to press the current connection piece 6. In this way, the current connection piece 6 is locked, as shown in Figures 1 and 2. Show. The resisting portion is disposed on one side of the lock 1 and is disposed close to the slot 12 and the hinged end of the lock 1 . The resisted portion has a contact surface 2 , and the unlocking piece of the short-circuit plug 9 cooperates with the contact surface 2 . When the plug is inserted into the slot 12, the unlocking member will act on the contact surface 2, forcing the locking end of the locking member 1 to tilt up. In this way, the locking of the current connecting piece 6 is released, as shown in Figure 3 and shown in Figure 4.

In a specific embodiment of the present invention, the abutment surface 2 in the abutment part is slope-shaped, correspondingly, the unlocking member is a wedge-shaped block 4, and the wedge-shaped surface of the wedge-shaped block 4 matches the abutment surface 2. When the plug of the short-circuit plug 9 is inserted into the slot 12, the wedge block 4 will slide along the contact surface 2, and the wedge block 4 will transmit a rotational force to the lock piece 1, forcing the lock piece 1 to rotate and tilt, thereby Achieve unlocking.

It should be noted that the contact surface 2 can also be a curved surface. This article does not specifically limit the shape of the contact surface 2, as long as it can ensure that the unlocking component transmits a continuous rotational force to the lock component 1 through the contact surface 2, thereby Making the lock 1 tilt falls into the protection scope of this article.

Please refer to the accompanying drawings 1, 2, and 3. In order to ensure that the unlocking member can accurately contact along the abutment surface 2, the present invention provides a limiter block 3. The limiter block 3 is provided opposite the abutment surface 2. It forms an entrance with the wedge-shaped surface. An adapter block 10 is provided on the wedge block 4, and the adapter block 10 can just enter the inlet. When the adapter block 10 of the wedge block 4 enters the inlet, the wedge surface of the wedge block 4 and the abutment surface 2 just form a fit.

It should be noted that if you want to ensure that the plug can be inserted into the slot 12, you must make the adapter block 10 enter the entrance and ensure that the wedge block 4 slides along the abutment surface 2. Otherwise, the anti-mislocking function will be affected. The butt will interfere with the short-circuit plug 9 and prevent the plug from being inserted.

Please continue to refer to the accompanying drawings 1, 2, and 3. An outlet 11 is formed between the limiting block 3 and the lock 1, and the outlet 11 is used for the adapter block 10 to move out. 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 located on the side. The adapter block 10 enters the inlet, the wedge block 4 slides along the abutment surface 2, and the lock 1 rotates close to 90°. At this time, the outlet 11 faces upward and the inlet turns to the side. If the secondary circuit of the current needs to be restored, the short-circuit plug 9 is pulled out of the slot 12 and the adapter block 10 of the wedge block 4 is moved out through the outlet 11 .

It should be noted that before pulling out the short-circuit plug 9, the current connection piece 6 needs to be reset first, so that the first flow guide piece 8 and the second flow guide piece 7 are electrically connected.

In order to ensure the smooth movement of the adapter block 10 between the inlet and the outlet 11, the present invention rounds the position of the limit block 3 at the inlet to form an inlet round corner, and at the same time, the limit block 3 is placed at the entrance. The area at exit 11 is rounded, forming the exit 11 rounded corner.

In order to ensure that the lock piece 1 provides effective pressing force on the current connecting piece 6, the lock end of the lock piece 1 is arranged in a hook shape.

From the above description, it can be seen that the mislock prevention mainly includes a lock piece 1 and a resisting part. The resisting part includes a contact surface 2 and a limiting block 3 . The present invention preferentially adopts the injection molding processing technology to produce the anti-accidental locking, and the integrated molding prevents the anti-accidental locking.

In addition, the component body is provided with a plurality of anti-mislocks arranged side by side. Correspondingly, the short-circuit plug 9 includes a plurality of unlocking parts arranged side by side. For example, in the case of four-core wiring, it is necessary to have four anti-accidental locks on the component body and four unlocking parts on the short-circuit plug 9, as shown in Figure 4.

In summary, the use process of the current secondary circuit terminal component is as follows: If you want to exit the current secondary circuit, you must first insert the plug of the short-circuit plug 9 into the notch of the slot 12, and at the same time make the adapter block 10 enter The entrance of the abutment part is then inserted into the slot 12, and at the same time, the wedge block 4 acts on the abutment surface 2, thereby causing the lock 1 to rotate and unlocking the current connecting piece 6. After that, the current connecting piece 6 can be slid out to exit the current secondary circuit. When it is necessary to restore the secondary circuit of the current, first reset the current connecting piece 6, connect the first guide piece 8 and the second guide piece 7, then pull out the short-circuit plug 9 upward, and remove the plug from the slot 12. The adapter block 10 moves out from the outlet 11 of the resisting part, and the lock 1 re-presses the current connecting piece 6 under the action of the torsion spring 5 .
