Detailed Description
The invention discloses a current secondary circuit terminal element which can prevent an open circuit from occurring.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a current secondary circuit terminal element which comprises an element body, a current connecting sheet 6 and a slot 12, and particularly further comprises an anti-false lock. The function of the anti-false lock is to lock the current connection piece 6. Short-circuit plug 9 includes unlocking piece 1, and after the plug of short-circuit plug 9 inserted slot 12 in, unlocking piece 1 on short-circuit plug 9 can the unblock mistake proofing lock, will then remove the locking to current connection piece 6, can remove current connection piece 6 this moment. If the short-circuit plug 9 is not inserted into the slot 12, the current lug 6 cannot slide out because the current lug 6 is locked by the anti-mislocking. Thus, the problem that the current connecting sheet 6 slides out when the short-circuit plug 9 is not inserted can be avoided, and the open circuit of the current secondary circuit is effectively avoided.
If the current secondary circuit needs to be withdrawn, the short circuit plug 9 needs to be inserted into the slot 12, the anti-false lock can be unlocked only after the short circuit plug 9 is inserted, the pressing force on the current connecting piece 6 can be released, then the current connecting piece 6 can be slid out, and the current secondary circuit can be withdrawn.
Next, a specific structure of the anti-mistake lock is described, and the anti-mistake lock specifically includes: a locking piece 1, a torsion spring 5 and a receiving part. The locking member 1 is hinged to the element body at one end, which is the hinged end. The end of the locking element 1 opposite to the hinged end is the locking end. A torsion spring 5 is provided at the hinged end, the torsion force of the torsion spring 5 forcing the locking end of the locking element 1 to press against the current lug 6, thus forming a locking of the current lug 6, as shown in fig. 1 and 2. The supported part is arranged at one side of the locking piece 1 and is arranged close to the slot 12 and the hinged end of the locking piece 1. The supported part is provided with a contact surface 2, and the unlocking piece 1 of the short circuit plug 9 is matched with the contact surface 2. During the insertion of the plug into the socket 12, the unlocking element 1 acts on the abutment surface 2, forcing the locking end of the locking element 1 to tilt, thus unlocking the current lug 6, as shown in fig. 3 and 4.
In an embodiment of the invention, the abutting surface 2 in the abutting portion is slope-shaped, correspondingly, the unlocking member 1 is a wedge-shaped block 4, and the wedge-shaped surface of the wedge-shaped block 4 is matched with the abutting surface 2. In the process that the plug of the short circuit plug 9 is inserted into the slot 12, the wedge block 4 slides along the abutting surface 2, the wedge block 4 transmits a rotating force to the locking piece 1, the locking piece 1 is forced to rotate and tilt, and therefore unlocking is achieved.
It should be noted that the abutting surface 2 may also be a similar arc surface, and the shape of the abutting surface 2 is not specifically limited herein, as long as it is ensured that the unlocking member 1 transmits a continuous rotating force to the locking member 1 through the abutting surface 2, so as to tilt the locking member 1, which falls into the protection scope of this document.
Referring to fig. 1, 2 and 3, in order to ensure that the unlocking member 1 can be accurately abutted along the abutting surface 2, the invention provides a limiting block 3, and the limiting block 3 is arranged opposite to the abutting surface 2 and forms an inlet with the wedge-shaped surface. The wedge block 4 is provided with an adapter block 10, which adapter block 10 can be inserted right into the inlet. When the adapter block 10 of the wedge block 4 is inserted into the inlet, the wedge surface of the wedge block 4 is just matched 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 into the entry and ensure that the wedge block 4 slides along the abutment surface 2, otherwise the anti-mislocking abutment would interfere with the short-circuit plug 9 and prevent 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 used for the adapter 10 to move out. The angle of the pinch between the outlet 11 and the inlet is approximately 90. In the starting position, the inlet is facing upwards and the outlet 11 is located at the side. The adapter piece 10 is brought into the entry and the wedge piece 4 is slid along the abutment surface 2 and the locking element 1 is rotated approximately 90, so that the exit 11 is now facing upwards and the entry is turned to the side. If the current secondary circuit needs to be restored, the short-circuit plug 9 is pulled out of the slot 12 and the adapter 10 of the wedge block 4 is removed through the outlet 11.
Before the shorting plug 9 is pulled out, the current connecting piece 6 needs to be reset to conduct the first guide vane 8 and the second guide vane 7.
In order to ensure the smoothness of the movement of the adapter block 10 between the inlet and the outlet 11, the part of the limiting block 3 at the inlet is rounded to form an inlet rounded corner, and the part of the limiting block 3 at the outlet 11 is rounded to form an outlet 11 rounded corner.
In order to ensure that the locking part 1 provides a sufficient contact pressure against the current web 6, the invention provides the locking end of the locking part 1 in the form of a hook.
From the above description, it can be known that the anti-mistake lock mainly includes the locking piece 1 and the supported portion, and the supported portion includes the butt face 2, the stopper 3. The invention preferentially adopts the processing technology of injection molding to manufacture the anti-error lock and integrally forms the anti-error lock.
In addition, the element body is provided with a plurality of false-proof locks arranged side by side, and correspondingly, the short-circuit plug 9 comprises a plurality of unlocking pieces 1 arranged side by side. For example, in the case of four-core connection, four mis-locking prevention parts are required to be arranged on the element body, and four unlocking parts 1 are arranged on the short-circuit plug 9, as shown in fig. 4.
In summary, the current secondary circuit terminal element is used as follows: if the current secondary circuit is to be withdrawn, the plug of the short-circuit plug 9 is inserted into the notch of the slot 12, the adapter block 10 is inserted into the entrance of the supported part, then the plug is inserted into the slot 12, and simultaneously, the wedge block 4 acts on the abutting surface 2, so that the locking piece 1 rotates, and the locking of the current connecting piece 6 is released. Then the current connecting piece 6 can slide out to exit the current secondary loop. When a current secondary loop needs to be restored, the current connecting piece 6 is reset firstly, the first flow deflector 8 and the second flow deflector 7 are conducted, then 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 supported part, and the locking piece 1 compresses the current connecting piece 6 again under the action of the torsion spring 5.
