Detailed implementation manners

[0033] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model and the prior art, the specific implementation manners of the present utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can be obtained.

[0034] The embodiment of the present utility model provides a plug-in terminal. Please refer to Figures 1 - 12 , which mainly includes an inner connector 1, an outer connector 2, a movable connector 3 and a locking member 4.

[0035] It should be noted that Figure 2 the up and down directions in Figure 2 are the up and down directions in the following text, and also the height direction; Figure 10 the left and right directions in

[0036] In an embodiment of the present application, the plug-in terminal includes an inner connecting member 1, an outer connecting member 2, a movable connecting member 3, and a locking member 4. The inner connecting member 1 is made of an elastic material. The inner connecting member 1 can be plugged onto or removed from the copper-aluminum busbar. The outer connecting member 2 is embedded on the outside of the inner connecting member 1. The movable connecting member 3 is rotatably connected to the outer connecting member 2. When one side of the movable connecting member 3 rises, the other side of the movable connecting member 3 descends. An integral elastic piece 5 is provided on the inner connecting member 1, and an integral adjusting block 6 is provided on the movable connecting member 3. The adjusting block 6 abuts against the elastic piece 5. When installing the terminal, first plug the inner connecting member 1 onto the copper-aluminum busbar, press the side of the movable connecting member 3 provided with the adjusting block 6, and the adjusting block 6 squeezes the elastic piece 5, causing the elastic piece 5 to deform, thereby increasing the contact area between the elastic piece 5 and the aluminum-copper busbar, enhancing the connection effect between the terminal and the aluminum-copper busbar. Then, embed the locking member 4 between the other side of the outer connecting member 2 and the movable connecting member 3. When the elastic piece 5 rebounds due to the restoring force, since one side of the locking member 4 abuts against the outer connecting member 2 and the other side abuts against the movable connecting member 3, the elastic piece 5 cannot rebound due to the position of the locking member 4. Thus, the terminal is locked onto the aluminum-copper busbar through the locking member 4. When removing the terminal, separate the locking member 4 from the outer connecting member 2. At this time, the locking effect of the locking member 4 is eliminated. Under the action of the restoring force, the elastic piece 5 pushes one side of the movable connecting member 3 to rise, and the other side of the movable connecting member 3 descends accordingly. The elastic piece 5 returns, reducing the contact area between the elastic piece 5 and the aluminum-copper busbar. Thus, the inner connecting member 1 can be separated from the copper-aluminum busbar, and the terminal can be removed. Compared with the prior art, in the prior art, when assembling the terminal, it is necessary to process the copper-aluminum busbar and fasten nuts or bolts during assembly. When removing the terminal, it is also necessary to loosen the nuts or bolts. The process of assembling and removing the terminal is cumbersome, the time required for assembly and removal is long, and the efficiency of assembling and removing the terminal is low. In the present application, during installation, the plug-in inner connecting member 1 is connected to the aluminum-copper busbar, and the terminal is locked onto the aluminum-copper busbar through the locking member 4. When removing, first pull out the locking member 4, and then the inner connecting member 1 can be directly separated from the copper-aluminum busbar. The installation and removal of the terminal can be completed without additional processing of the aluminum-copper busbar. The assembly and removal processes are simple, the time required for assembly and removal is short, and the efficiency of assembling and removing the terminal is improved.

[0037] It should be noted that the plug-in terminal of the present application can be applied not only to copper-aluminum busbars but also to copper busbars, aluminum busbars, or other plate-like structures.

[0038] Specifically, the elastic piece 5 is divided into a straight plate portion and a bent portion. The straight plate portion and the bent portion are integrally connected to form the elastic piece 5. The straight plate portion abuts against the adjusting block 6. When locking the terminal, the straight plate portion of the elastic piece 5 abuts against the aluminum-copper busbar. When unlocking the terminal, the bent portion of the elastic piece 5 abuts against the aluminum-copper busbar.

[0039] In an implementable manner, a rotating groove 21 is provided on the outer connecting member 2, and a rotating shaft 31 is provided on the movable connecting member 3. The rotating shaft 31 is embedded in the rotating groove 21, and the entire movable connecting member 3 can rotate around the rotating shaft 31. When the side of the movable connecting member 3 where the adjusting block 6 is provided rises, the side of the movable connecting block away from the adjusting block 6 descends. The adjusting block 6 is provided on the side of the movable connecting member 3 away from the locking member 4, and the adjusting block 6 is the farthest from the rotating shaft 31. At the same rotation angle, the moving distance of the adjusting block 6 is the largest, so that the deformation amount of the elastic piece 5 reaches the maximum, the contact area between the elastic piece 5 and the aluminum copper row increases, the connection effect between the terminal and the aluminum copper row is enhanced, and the adjusting block 6 is the farthest from the rotating shaft 31 and the force arm is the largest, and the force required for the adjusting block 6 to move is the smallest, which is convenient for the operator to operate. When installing the terminal, first insert the inner connecting member 1 onto the copper-aluminum row, press the side of the movable connecting member 3 where the adjusting block 6 is provided, the adjusting block 6 squeezes the elastic piece 5 so that the elastic piece 5 deforms, the side of the movable connecting member 3 where the adjusting block 6 is provided descends, and the other side rises. Then insert the locking member 4 between the outer connecting member 2 and the other side of the movable connecting member 3. When the elastic piece 5 rebounds due to the restoring force, the other side of the movable connecting member 3 has a tendency to descend, but since one side of the locking member 4 abuts against the outer connecting member 2 and the other side abuts against the other side of the movable connecting member 3, the elastic piece 5 cannot rebound due to the position of the locking member 4, and thus the terminal is locked on the aluminum copper row through the locking member 4; when the terminal needs to be removed, separate the locking member 4 from the outer connecting member 2. At this time, the locking effect of the locking member 4 is eliminated. Under the action of the restoring force, the elastic piece 5 pushes one side of the movable connecting member 3 to rise, and the other side of the movable connecting member 3 descends accordingly. The restoration of the elastic piece 5 reduces the contact area between the elastic piece 5 and the aluminum copper row, and thus the inner connecting member 1 can be separated from the copper-aluminum row to remove the terminal.

[0040] Furthermore, a locking groove 22 is provided on the outer connecting member 2. The locking member 4 includes a handheld plate 41 and a baffle plate 42. The baffle plate 42 is fixedly connected to the handheld plate 41. A locking block 44 is provided on the baffle plate 42, and the locking block 44 is embedded in the locking groove 22. Moving the handheld plate 41 drives the entire locking member 4 to move along the direction in which the locking groove 22 is arranged. When the terminal needs to be locked, move the handheld plate 41 to drive the entire locking member 4 to move towards the direction where the adjusting block 6 is located, so that the movable connecting member 3 abuts against the baffle plate 42 to lock the terminal; when the terminal needs to be unlocked, move the handheld plate 41 to drive the entire locking member 4 to move away from the adjusting block 6, so that the movable connecting member 3 is separated from the baffle plate 42 to unlock the terminal.

[0041] Preferably, a card slot 32 is provided on the movable connecting piece 3. The locking piece 4 further includes a connecting plate 43. The length of the connecting plate 43 is greater than that of the baffle 42, and the width of the connecting plate 43 is less than the width of the card slot 32. A blocking block 45 is provided on one side of the connecting plate 43 close to the inner connecting piece 1. Pull the handheld plate 41 to drive the entire locking piece 4 to move away from the adjusting block 6 until the blocking block 45 abuts against the outer connecting piece 2. At this time, the baffle 42 no longer contacts the movable connecting piece 3, and the terminal is unlocked, but the connecting plate 43 contacts the movable connecting piece 3. At this time, press the side of the movable connecting piece 3 provided with the adjusting block 6. When released, the elastic piece 5 rebounds and will embed the movable connecting piece 3 on the connecting plate 43. When the terminal needs to be locked, move the entire locking piece 4 towards the direction where the adjusting block 6 is located to lock the terminal. By providing the connecting plate 43 and the card slot 32, whether the terminal is in the locked state or the unlocked state, the locking piece 4 is located between the movable connecting piece 3 and the outer connecting piece 2, which is convenient for the terminal to switch between the locked state and the unlocked state.

[0042] In an implementable manner, a wiring port 23 is provided on the outer connection block. The inner connecting piece 1 includes a copper-aluminum row connecting block 11 detachably inserted on the aluminum-copper row, and a wire connecting block 12 for connecting a wire. One end of the wire connecting block 12 passes through the wiring port 23 and is integrally connected to the copper-aluminum row connecting block 11.

[0043] Specifically, in one implementation, as Figure 5 shown, the wire connecting block 12 is square, and the wire connecting block 12 is connected to the wire by welding. In another implementation, as Figure 6 shown, the wire connecting block 12 is provided with a wire pressing groove, and the wire connecting block 12 is connected to the wire by crimping.

[0044] Furthermore, the copper-aluminum row connecting block 11 includes a first plate 111, a second plate 112, and a third plate 113; the first plate 111, the second plate 112, and the third plate 113 are connected to form a "C"-shaped structure. The elastic piece 5 is arranged on the first plate 111, and an installation piece 114 is provided on the second plate 112. During the process of installing and removing the terminal, when the installation piece 114 contacts the aluminum-copper row, the installation piece 114 will deform, which is convenient for the insertion and extraction of the terminal and the aluminum-copper row.

[0045] Preferably, a slot 24 is provided on the outer connecting piece 2. The first plate 111 and the second plate 112 are embedded in the slot 24. A connecting piece 115 is provided on the third plate 113. The connecting piece 115 deforms during the connection process of the inner connecting piece 1 and the outer connecting piece 2, so that the first plate 111 and the second plate 112 are more easily inserted into the slot 24, which is convenient for the connection of the inner connecting piece 1 and the outer connecting piece 2.

[0046] In an implementable embodiment, the inner connector 1 is made of brass with a tin-plated surface. Tin plating is applied to the brass surface to prevent the brass from being corroded, thereby improving the antioxidant performance and aesthetics of the inner connector 1.

[0047] In an implementable embodiment, the outer connector 2, the movable connector 3, and the locking member 4 are made of polyhexamethylene adipamide (PA66). Modified PA66 can also be formed by adding different additives to polyhexamethylene adipamide or blending it with other materials to increase rigidity, improve heat resistance, etc., and then the outer connector 2, the movable connector 3, and the locking member 4 are manufactured.
