Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, specifically to a rotary unlocking current terminal block. Background Technology
[0002] With the continuous development of power technology and the widespread application of electrical equipment, the use of current terminals is also increasing. Since terminals need to be plugged in and unplugged for replacement or maintenance, but also need to be tightened, most high-current terminals are designed without special unlocking tools, mainly using threaded tightening or side-pinch snap-locking structures. However, this structure is prone to accidental unlocking and is inconvenient to unlock. In addition, some current terminals need to be equipped with nuts, but riveting nuts will damage the electroplating layer of the nut and current guide strip, reducing the salt spray effect. Even if electroplating is done before riveting, it will still have an impact. Therefore, we propose a rotary unlocking current terminal that can achieve unlocking in small spaces and is easy to disassemble without reducing the product's salt spray requirements.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-6 As shown, this utility model is a rotary unlocking current terminal block, including a main body 1, a waterproof cover 2 is inserted into one side of the main body 1, and a tail cap 22 is threadedly connected to the end of the waterproof cover 2 away from the main body 1.
[0034] Among them, a claw 21 is provided inside the connection between the tail cap 22 and the waterproof cover 2. One end of the claw 21 is provided with several buckles 210, which are adapted to several slots 23 opened at the end of the waterproof cover 2 away from the main body 1, so as to prevent the claw 21 from rotating during the connection process and affecting the stability of the wiring. At the same time, a cable sealing ring 211 is also provided inside the claw 21 to ensure the connection is sealed.
[0035] A snap ring 11 is provided on one side of the main body 1, a flow guide seat 12 is provided inside the snap ring 11, a flow guide strip 14 is provided on the flow guide seat 12, and an inner nut 141 is provided on the flow guide strip 14.
[0036] Meanwhile, a slot 110 is provided on the snap ring 11, and an installation slot 24 is provided at one end of the waterproof cover 2. The end of the waterproof cover 2 is inserted into the snap ring 11, and the installation slot 24 is provided in the slot 110. At the same time, a connecting sealing ring 121 is provided between the main body 1 and the waterproof cover 2. After the end of the waterproof cover 2 is inserted into the snap ring 11, the installation slot 24 enters along the slot 110, and can be locked after rotation.
[0037] In addition, a sliding button 3 is slidably provided on the top of the waterproof cover 2. One end of the sliding button 3 is snapped into the slot 110. The sliding button 3 can restrict the connection between the waterproof cover 2 and the main body 1, so as to prevent the waterproof cover 2 from loosening and detaching after it is snapped into the main body 1.
[0038] Specifically: A fixed slide groove 20 is provided on the top of the waterproof cover 2, a spring rod 201 is provided in the fixed slide groove 20, a spring 4 is sleeved on the spring rod 201, and the sliding button 3 is slidably provided in the fixed slide groove 20 and is provided on the spring rod 201.
[0039] Among them, the slider 3 includes a slider body 31, one end of which is provided with a spring movable position 310. The slider body 31 is slidably disposed in the fixed slide groove 20, and the spring 4 is located in the spring movable position 310.
[0040] Meanwhile, guide grooves 202 are symmetrically provided on both sides inside the fixed slide groove 20; guide rails 33 are symmetrically provided on both sides of the slide button body 31, and the guide rails 33 are slidably disposed in the guide grooves 202.
[0041] A limiting position 203 is symmetrically provided at one end of the fixed slide groove 20; a limiting hook 34 is symmetrically provided on both sides of the spring movable position 310 at the end of the slide button body 31, and the limiting hook 34 is engaged with the limiting position 203.
[0042] A limit block 32 is provided at the end of the slider body 31 away from the limit hook 34;
[0043] During installation and use, a spring 4 is fitted onto the spring rod 201, and the sliding button body 31 is slidably set in the fixed sliding groove 20. The two limit hooks 34 at the end slide in the two limit positions 203 to prevent slippage. Then, the guide rails 33 on both sides are slidably set in the guide groove 202. In the static state, the spring 4 is in a compressed state. The spring 4 pushes the entire sliding button 3 to one end close to the main body 1. At this time, the limit block 32 can be inserted into the slot 110, thereby realizing the snap-fit connection between the waterproof cover 2 and the main body 1, avoiding the problem of falling off due to mutual rotation.
[0044] During use, by pushing the sliding button 3 all the way away from the main body 1, and then rotating the waterproof cover 2, the waterproof cover 2 can be detached from the main body 1.
[0045] A bracket 13 is provided on the side of the main body 1 away from the waterproof cover 2. A buckle 131 is provided on the bracket 13. An outer nut 132 is provided on the bracket 13 and below the buckle 131. A socket sealing ring 130 is provided on the side of the main body 1 away from the waterproof cover 2. The outer nut 132 is installed in the buckle 131 to separate it from the guide strip 14 without reducing the salt spray requirements.
[0046] The assembly method for this product is as follows:
[0047] a: Install the connecting sealing ring 121 and the socket sealing ring 130 on the groove of the main body 1;
[0048] b: Install the guide strip 14 in the required direction on the guide seat 12 on the side of the main body 1;
[0049] c: After placing the outer nut 132 on the mounting position below the buckle 131, align it and install it on the main body 1;
[0050] d: Install the spring 4 on the spring rod 201 in the fixed slide groove 20 on the waterproof cover 2, and then press the slide button 3 in forcefully;
[0051] e: After assembling the cable sealing ring 211 with the claw 21, install it on the back side of the waterproof cover 2, and then cover it with the tail cap 22;
[0052] f: Align the mounting slot 24 of the waterproof cover 2 with the slot 110 on the main body 1 and push it all the way down. Then rotate the waterproof cover 2 clockwise. When you see the sliding button 3 spring back or hear a knocking sound, the installation is complete.
[0053] The sliding button 3 is slidably set in the fixed groove 20 to lock the waterproof cover 2 and the main body 1 together, avoiding the problem of falling off due to mutual rotation. During the installation and unlocking process, the disassembly and connection can be achieved by one hand, which not only ensures the stability of the terminal connection, but also makes the operation simple and convenient, solving the problem of cumbersome terminal connection operation.
