Description

Technical Field

[0001] This utility model relates to the field of insulating terminal technology, and specifically to an easily detachable insulating terminal. Background Technology

[0002] An insulating terminal is an electrical connector used to connect wires. A search of existing technology (application number: CN202321816693.2) describes "an easily detachable insulating terminal, comprising an insulating terminal body, a contact port, and a sleeve hole; wherein, the insulating terminal body has contact ports at both its upper and lower ends, and a sleeve hole is welded to the right side wall of the insulating terminal body; further comprising: wire outlets at both the upper and lower ends of the sleeve hole, and the other end of a return spring fixed to the outer wall of the sleeve hole, with a limit ring fixed to the end of the return spring extending into the sleeve hole; and rotating screws bearing-connected to both the upper and lower surfaces of the insulating terminal body. This easily detachable insulating terminal is equipped with a moving block, and the threaded rotating screws allow the moving block to slide stably inside the insulating terminal body via a groove, so that the moving block drives a wedge to press against a moving rod, causing the moving rod to adhere and limit the wire through a bonding plate, thus achieving simple disassembly and installation."

[0003] However, while the existing easy-to-remove insulating terminals achieve the effect of easy disassembly, they still have some shortcomings: when connecting the existing easy-to-remove insulating terminals to the wires, the wires must first be inserted into the sleeve hole and pressed tightly, and then inserted into the contact port and fixed by turning the screw. The process is relatively troublesome and requires disassembly and assembly tools. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, an easily detachable insulating terminal is provided to solve the problem that the disassembly and assembly process of the existing easily detachable insulating terminal and wire is still relatively troublesome and requires additional disassembly and assembly tools.

[0005] To achieve the above objectives, an easily detachable insulating terminal is provided, comprising: a base, a wire pressing assembly, and a drive assembly. The base has a wire pressing groove at its upper end, and the wire pressing groove has an anti-slip toothed surface and a pin inside. The wire pressing assembly includes a rocker arm, and a pressing block is connected to the lower end of the rocker arm. The bottom of the pressing block has a slot and a wire pressing post. The bottom of the pressing block is rotatably connected to the pin. The drive assembly includes a threaded rod, and a slip ring is slidably sleeved on the outside of the threaded rod. A connecting rod is movably connected between the slip ring and the rocker arm. A spring is provided on the outside of the threaded rod and below the slip ring. The lower end of the threaded rod is vertically fixed to the upper end of the base.

[0006] Furthermore, the pressure grooves are symmetrically opened on both sides of the base, and the anti-slip tooth surface has downward inclined surfaces on both sides, and a buffer pad is provided at the lower end of the anti-slip tooth surface.

[0007] Furthermore, the base has a connecting groove inside, and a conductive sheet is provided at the bottom of the connecting groove, and the connecting groove is connected to the pressure grooves on both sides.

[0008] Furthermore, the outer wall of the swing rod is connected to a hinge block, and the inner end of the hinge block is connected to a hinge groove, and the outer end of the connecting rod is rotatably connected in the hinge groove.

[0009] Furthermore, the upper side wall of the slot is provided with a pressure sleeve end face, and the two side end faces of the slot are provided with inclined end faces, and the slot is matched and engaged with the anti-slip tooth surface.

[0010] Furthermore, a hinge hole is provided at the inner corner of the lower end of the pressure block, and a pin is rotatably connected through the hinge hole.

[0011] Furthermore, a threaded sleeve is screwed onto the outer side of the threaded rod, and a handle is symmetrically connected to the outer wall of the threaded sleeve. The threaded sleeve is located on the upper side of the slip ring, and a limiting block is provided at the upper end of the threaded rod.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When using, align the stripped end of the wire with the wire slot and insert it so that the copper wire segment is under the wire slot and the wire sheath is under the anti-slip tooth surface. Then, rotate the screw sleeve by the handle to drive the slip ring to slide down and compress the spring, which in turn pushes the connecting rod outward to open up. This causes the rocker arm to drive the pressure block to rotate until the end face of the toothed sleeve presses the unstripped wire against the anti-slip tooth surface, and the wire slot presses the stripped copper wire against the conductive plate. This completes the connection and connection of the wires. When disassembling, simply rotate the screw sleeve. At this time, the rocker arm will move closer and rotate under the action of the spring, and the wire can be pulled out, making the disassembly and assembly process more convenient.

[0014] 2. By utilizing two sets of wire clamping components, the wires inserted into the wire clamping slots of the base can be clamped simultaneously when the drive component is operated at the same time, improving wiring efficiency. At the same time, the clamping blocks, including the slots and clamping posts of the clamping blocks, make it easy to clamp the sliding sleeve section and the copper wire section of the wire in one go. The square plate and the sheath section are bent by the inclined surfaces on both sides of the anti-slip tooth surface, which provides an anti-pulling and dragging effect. In addition, only the handle needs to be turned during disassembly and assembly, and no other disassembly and assembly tools are required, making it very convenient to use.

A threaded sleeve 34 is screwed on the outside of the threaded rod 31, and a handle 35 is symmetrically connected to the outer wall of the threaded sleeve 34. The threaded sleeve 34 is located on the upper side of the slip ring 33. At the same time, a limiting block 36 is provided at the upper end of the threaded rod 31.

[0021] In this embodiment, the base 1, the wire clamping assembly 2, and the drive assembly 3 constitute the main structure of the easily detachable insulating terminal involved in this application.

[0022] Specifically, the wire pressing groove 11 can be provided with multiple symmetrical sets on the base 1, and each set is matched with a drive component 3 and two sets of wire pressing components 2. At the same time, the base 1 can be fixed horizontally or vertically.

[0023] Specifically, there is a certain angle between the rocker arm 21 and the pressure block 24 on the outward side, and the angle is set to an acute angle.

[0024] Specifically, the pressure post 243 is designed as a semi-cylindrical structure and is made of insulating material.

[0025] As a preferred implementation, the handle 35 facilitates the direct linear motion of the slip ring 33.

[0026] like Figure 2 and Figure 3 In the middle, the pressure grooves 11 are symmetrically opened on both sides of the base 1, and the anti-slip tooth surface 14 has downward inclined surfaces 13 on both sides, and a buffer pad 15 is provided at the lower end of the anti-slip tooth surface 14.
