Description

Technical Field

[0001] The utility model relates to the technical field of insulating terminals for capacitors, in particular to an insulating terminal for a capacitor. Background Art

[0002] Insulated terminals are metals sealed in insulating plastic. There are holes at both ends of the terminals for inserting wires. Insulated terminals can be used to connect or disconnect wires.

[0003] For example, a capacitor insulating terminal with the announcement number "CN202695135U" has a through hole for the lead wire to pass through at the bottom of the insulating sleeve. The bottom of the insulating sleeve is the welding area for the capacitor lead terminal and the lead wire. It adopts a rectangular insulating sleeve structure design, and the two short sides of the rectangular insulating sleeve are designed to be arc-shaped, which fully utilizes the space on the upper end face of the capacitor, can effectively increase the weldable area, reduce the difficulty of welding operation and improve the reliability of welding, effectively improve the welding efficiency, and reduce the occurrence of cold welding. However, when the insulating terminal is in use, the connection between the capacitor and the insulating terminal is a single-point connection, and pulling will occur during the installation of the insulating terminal. The connection of the insulating terminal is a single-point connection, which makes it easy for the capacitor and the insulating terminal to be disconnected, increasing the difficulty of installing the capacitor and affecting the normal use of the capacitor. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An insulating terminal for a capacitor is designed, comprising an insulator and a sheath, wherein the outer wall of the insulator is fitted with the inner wall of the sheath, a contact piece is fixedly connected to the front of the insulator, the rear of the outer wall of the contact piece is plugged into the front notch of the sheath, the rear of the outer wall of the sheath is connected to a reinforcement structure, and the inner wall of the contact piece is connected to a support structure.

[0007] Preferably, the reinforcement structure includes a circular ring and a straight plate, the inner wall of the circular ring is fixedly connected to the rear of the outer wall of the sheath, the top left side of the circular ring is fixedly connected to the bottom of the straight plate, the right side of the straight plate is fixedly connected to a cross bar, and the top right side of the circular ring is fixedly connected to a groove plate.

[0008] Preferably, the outer wall of the cross bar is plugged into the inner wall of the slot plate.

[0010] Preferably, the support structure includes a screw and a notch, the outer wall of the screw is threadedly connected to the inner wall of the contact piece, the front surface of the screw is processed with a notch, and the rear end face of the screw is fixedly connected to a circular plate.

[0011] Preferably, the rear end surface of the circular plate is tightly pressed against the front surface of the sheath.

[0012] The utility model provides an insulating terminal for a capacitor, which has the following beneficial effects: the straight plate and the slot plate are pushed inward by the hand in the reinforcement structure, and at this time the upper part of the circular ring moves inward, and the circular ring as a whole is deformed to be squeezed inward, and the deformation of the circular ring squeezes the sheath, so that the sheath presses the connection position tightly, and then the ring is rotated to the left through the thread of the outer wall of the cross bar, so that the ring and the right side of the slot plate are pressed tightly, thereby completing the fixation of the ring and realizing the reinforcement of the connection of the insulating terminal, reducing the difficulty of installing the capacitor and ensuring the normal use of the capacitor.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-4 : In this embodiment, an insulating terminal for a capacitor includes an insulator 1 and a sheath 4. The outer wall of the insulator 1 is in contact with the inner wall of the sheath 4. The sheath 4 is made of rubber. A contact piece 5 is fixed to the front of the insulator 1. The rear of the outer wall of the contact piece 5 is plugged into the front groove of the sheath 4. The rear of the outer wall of the sheath 4 is connected to a reinforcement structure 2, and the inner wall of the contact piece 5 is connected to a support structure 3.

[0021] The reinforcement structure 2 includes a circular ring 201 and a straight plate 202. The inner wall of the circular ring 201 is fixedly connected to the rear of the outer wall of the sheath 4. The top left side of the circular ring 201 is fixedly connected to the bottom of the straight plate 202. A crossbar 203 is fixedly connected to the right side of the straight plate 202. The right side of the outer wall of the crossbar 203 is processed with a thread. A groove plate 204 is fixedly connected to the top right side of the circular ring 201. The outer wall of the crossbar 203 is plugged into the inner wall of the groove plate 204. The right side of the outer wall of the crossbar 203 is threadedly connected to a collar 205. The collar 205 is subjected to force and rotates left and right through the thread on the right side of the outer wall of the crossbar 203.

[0022] By using the hand in the reinforcement structure 2, the straight plate 202 and the groove plate 204 are pushed inward. At this time, the upper part of the ring 201 moves inward, and the ring 201 as a whole is deformed and squeezed inward. Due to the deformation of the ring 201, the sheath 4 is squeezed, so that the sheath 4 presses the connection position tightly. Then the ring 205 is rotated to the left through the thread on the outer wall of the cross bar 203, so that the ring 205 is pressed against the right side of the groove plate 204, completing the fixation of the ring 201, realizing the reinforcement of the connection of the insulating terminal, reducing the difficulty of installing the capacitor, and ensuring the normal use of the capacitor.

[0023] The support structure 3 includes a screw 301 and a slot 302. The outer wall of the screw 301 is threadedly connected to the inner wall of the contact piece 5. The screw 301 is subjected to force and rotates back and forth through the inner wall of the contact piece 5. The front of the screw 301 is processed with a slot 302. The rear end face of the screw 301 is fixed with a circular plate 303. The circular plate 303 is a rubber plate. The rear end face of the circular plate 303 is tightly pressed against the front face of the sheath 4.

[0024] Working principle:

[0025] Insulated terminal installation:

[0026] The insulator 1 and the contact piece 5 form an insulating terminal. The sheath 4 is passed through the contact piece 5 from the right front to the rear and is sleeved on the outer wall of the insulator 1. Then the connection of the capacitor is connected to the connection of the insulator 1. Then, the straight plate 202 and the slot plate 204 are pushed inward by the hands. At this time, the upper part of the ring 201 moves inward, and the ring 201 as a whole is deformed and squeezed inward. Due to the deformation of the ring 201, the sheath 4 is squeezed, so that the sheath 4 presses the connection position tightly. Then the ring 205 is rotated to the left through the thread on the outer wall of the cross bar 203, so that the ring 201 is pressed against the right side of the slot plate 204, completing the fixation of the ring 201 and realizing the reinforcement of the insulating terminal connection.

[0027] Insulated terminal support:

[0028] The external plug-in rod is plugged into the notch 302 on the front of the screw 301, and the plug-in rod drives the screw 301 to rotate. The rotating screw 301 rotates backward through the contact piece 5, and then drives the circular plate 303 to move backward, so that the rear of the circular plate 303 is pressed against the front of the sheath 4, completing the support for the contact piece 5.

[0029] Example 2:

[0030] See also Figure 1-4 : In this embodiment, an insulating terminal for a capacitor further includes a vertical rod 6, the bottom of the vertical rod 6 is fixedly connected to the top of the ring 201.

[0031] Working principle:

[0032] When rotating the ring 201 , one can clamp one side of the vertical rod 6 with one finger, and then rotate the ring 201 through the vertical rod 6 .
