Abstract
Description
Technical Field
[0001] The utility model relates to a connection terminal spring piece, belonging to the technical field of connection terminal spring pieces. Background Art
[0002] Electrical connectors are usually composed of metal terminals and metal matching terminals. Electrical conduction is formed by plugging the terminals into the matching terminals to transmit current or signals. They are the carriers for achieving electrical connection. For traditional circuit breaker terminals, insert the wire into the wiring hole and then operate the fastening screw to press the pressure piece at the rear end of the fastening screw against the wire.
[0003] There are still some problems with the existing terminal spring clip during use. For example, when the terminal spring clip is not in use, since there is no protective mechanism on the outside of the device, external dust will enter the inside of the wiring port and affect the sensitivity of subsequent wiring. At the same time, the conductive rod is always in an exposed state when not in use, which may cause damage to itself. Utility Model Content
[0004] The purpose of the utility model is to provide a terminal spring clip. The utility model has a simple structure and is easy to use. It can cover the wiring port when not in use to prevent external dust from entering the interior of the wiring port, and can protect the conductive rod to prevent damage, so as to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A terminal spring piece comprises a mounting shell, wherein a wiring groove is provided inside the mounting shell, an extrusion screw is rotatably connected inside the mounting shell, a conductive rod is fixedly connected to the outside of the mounting shell, a connecting plate is fixedly connected to the outside of the mounting shell, a rotating rod is rotatably connected inside the connecting plate, a rotating ring is fixedly connected to the outside of the rotating rod, a U-shaped rod is fixedly connected to the outside of the rotating ring, a sealing plate is fixedly connected to the bottom of the U-shaped rod, a magnetic pole plate is fixedly connected to the outside of the sealing plate, a stabilizing seat is fixedly connected to the outside of the mounting shell, a transmission rod is rotatably connected inside the stabilizing seat, and a limiting plate is fixedly connected to the outside of the transmission rod.
[0007] Furthermore, a fixing seat is fixedly connected to the outer side of the mounting shell, a return spring is fixedly connected to the outer side of the fixing seat, and a dust cover is fixedly connected to the outer side of the return spring.
[0008] Furthermore, the wiring slots are evenly distributed inside the mounting shell, and the bottom of the extrusion screw is rotatably connected to the inside of the wiring slots.
[0009] Furthermore, the connecting plates are symmetrically distributed on the outside of the installation shell, and the sealing plate is movably connected to the outside of the installation shell through a rotating rod and a U-shaped rod.
[0010] Furthermore, the number of the magnetic pole plates is the same as that of the sealing plates, the limiting plates are made of iron sheets, and the limiting plates are rotatably connected to the outer side of the sealing plates.
[0011] Furthermore, the fixing seats are evenly distributed on the outside of the mounting shell, and the number of the return springs is the same as the number of the fixing seats.
[0012] Furthermore, the inner diameter of the dust cover is greater than the outer diameter of the conductive rod, and the length of the dust cover is greater than the length of the conductive rod.
[0013] The beneficial effects of the utility model are:
[0014] (I) The utility model is provided with an installation shell, and a wiring groove is opened inside the installation shell. When the wiring groove is not needed, the U-shaped rod is first used in cooperation with the rotating rod and the rotating circle, so that the sealing plate is driven to rotate. At this time, the sealing plate is rotated to the outside of the wiring groove, so as to shield the wiring groove. Then, the transmission rod is rotated inside the stabilizing seat, so that the transmission rod drives the limit plate to rotate. When the limit plate is rotated to the outside of the magnetic pole plate, since the limit plate is made of iron, it will attract each other, so that the limit plate limits the sealing plate. At this time, the sealing plate will play a dust-proof role for the wiring groove, preventing external dust from entering the interior of the wiring groove. When the device needs to be used, it is only necessary to open the sealing plate.
[0015] (ii) The utility model provides a mounting shell, to which a conductive rod is fixedly connected on the outside of the mounting shell. When the conductive rod needs to be protected, the reset spring first moves the dust cover, so that the dust cover is snapped onto the outside of the conductive rod, thereby protecting the conductive rod. When the conductive rod is in use, the dust cover only needs to be moved out from the outside of the conductive rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In the present embodiment: by setting up an installation shell 1, a wiring slot 2 is opened inside the installation shell 1. When the wiring slot 2 is not needed, first, the rotating rod 6 and the rotating circle 7 are used in cooperation, so that the U-shaped rod 8 drives the sealing plate 9 to rotate. At this time, the sealing plate 9 will rotate to the outside of the wiring slot 2, thereby shielding the wiring slot 2. Then, the transmission rod 12 is rotated inside the stable seat 11, so that the transmission rod 12 drives the limiting plate 13 to rotate. When the limiting plate 13 rotates to the outside of the magnetic pole plate 10, since the limiting plate 13 is made of iron, it will attract each other, so that the limiting plate 13 limits the sealing plate 9. At this time, the sealing plate 9 will play a dust-proof role for the wiring slot 2, preventing external dust from entering the interior of the wiring slot 2.
