CN201813058U - A compression structure of a cold-press terminal - Google Patents

Abstract

The utility model belongs to the technical field of machinery, and particularly relates to a pneumatic compression structure, which is capable of performing balanced compression after a wire end is connected into a cold pressing connection terminal. The pneumatic compression structure is characterized in that a cylinder is designed to drive a connecting post to move vertically, vertical movement limit of the cylinder is controlled by an air inlet valve so that vertical limit of an upper pressing plate is controlled and the same position of the upper pressing plate is kept when the upper pressing plate is pressed down in each time, and balanced compression for the cold pressing connection terminal is performed precisely. A supporting plate is connected to the upper end of a base and used for mounting the cylinder, air inflow is controlled by the air inlet valve on the cylinder so that the air inflow of the cylinder in each time is kept same, and accordingly the press-down positions of a cylinder rod in each time are kept uniform under the action of the cylinder. Simultaneously, the cylinder rod and the connecting post are fixed together, and the connecting post and the upper pressing plate are fixed, so that the press-down positions of the upper pressing plate in each time can be ensured to the same, the force exerted to the wire end connected into the cold pressing connection terminal in each time is the same, and ideal compression effect can be achieved.

Description

A compression structure of a cold-press terminal

Technical field:

The utility model belongs to the technical field of machinery, and in particular designs a pneumatic compaction structure, which can perform balanced compaction after the thread head is connected to a cold-press terminal.

Background technique:

Cold-pressed terminals or wire lugs, one end is used to connect wires, it is in the shape of a round hole, and the other end is connected to the application equipment and other facilities. Insert the wire head from the end of the round hole type, then clamp it with a tool, and connect the other end to the application equipment On, the connection of electric current can be realized. Generally speaking, when the wire end enters the round hole end of the cold-pressed terminal, it must be clamped with a tool so that the wire end will not come out. Generally, the cold-pressed terminal crimping pliers are used, but because it is manual operation, The pressing force used each time must be different, which makes the force uneven. If it is light, the thread end may fall off easily, and if it is heavy, the thread end may be broken. This is very inefficient and the quality cannot be guaranteed.

Utility model content:

The utility model designs a pneumatic compaction structure, which can carry out balanced compaction after the wire head is connected to the cold-press terminal.

The utility model includes a base, a support plate, a cylinder, an intake valve, a connecting column, an upper pressing plate, a lower pressing plate, a hinge, a hinge column, and a cylinder rod. It is characterized in that a cylinder is designed to drive the connecting column to move up and down. Control the upper and lower movement limit of the cylinder, thereby controlling the upper and lower limit of the upper pressing plate, so that the same position is maintained each time the upper pressing plate is pressed down, and the balanced pressing of the cold-pressed terminal is accurately carried out. The utility model connects the upper and lower pressing plates through the action of the hinge, so that the upper pressing plate can move freely when being acted by the cylinder.

The compression structure principle of the cold-pressed terminal described in the utility model is simple, and the production and acquisition of parts are simple and convenient, which saves the cost to the greatest extent, and can make the force of each wire end connected to the cold-pressed terminal the same , to achieve the ideal pressing effect, and can effectively improve work efficiency.

Description of drawings:

Fig. 1 is a front view of the utility model.

Detailed ways:

Referring to Fig. 1, the lower pressing plate 7 is fixed on the base 1, the upper pressing plate 6 and the lower pressing plate 7 are connected together through the hinge column 9, and then the upper pressing plate 6, the lower pressing plate 7 and the hinge column 9 are connected with the hinge 8 to realize the up and down Hinge of the pressure plate. A support plate 2 is connected to the upper end of the base 1 to install the cylinder 3, and the intake valve 4 is used to control the intake air volume on the cylinder 3, so that the intake air volume of the cylinder 3 remains the same each time, so that the effect of the cylinder 3 Keep the cylinder rod 10 in the same position every time, and at the same time fix the cylinder rod 10 and the connecting column 5 together, fix the connecting column 5 and the upper pressing plate 6, so that it can ensure that the lower pressing plate 6 each time The pressure position is the same, so that each time the wire end is connected to the cold-pressed terminal, the force is the same, and the ideal pressing effect is achieved.
