Description

Clamping type wiring terminal

Technical Field

The utility model relates to a binding post of joint formula.

Background

The traditional two wires are usually connected in a welding or winding mode, the mode is usually not easy to loosen or loose due to loose connection, the problem is solved just by the appearance of the wiring terminal, holes in the two ends of the wiring terminal can be inserted into the wires, the wires are fastened or loosened through screws, the two wires are connected together in a connection mode of the wiring terminal and can be disconnected or connected at any time, the fastening is reliable, the wires are not easy to fall off, and the use is convenient and fast. However, the conventional connection terminal is usually fastened by screws, and in the actual operation of the conventional connection terminal, the screws need to be frequently screwed, so that the conventional connection terminal is complicated and the working efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a binding post of joint formula has effectively solved the problem of pointing out among the background art.

The utility model adopts the technical proposal that:

the utility model provides a binding post of joint formula, includes the shell, the shell be around both sides open-ended mouth style of calligraphy, the top inboard of shell is equipped with the spring, the bottom of spring is fixed with the clamp plate, the clamp plate is fixed with a guide arm respectively in the bottom at four apex angles, the below of shell is stretched to the bottom that the guide arm passed the shell, four the bottom mounting of guide arm has the button, the bottom center of clamp plate is fixed with upper locking piece, the inboard center in bottom of shell is fixed with lower locking piece.

Preferably, the spring is mounted on the top of the housing by a spring seat.

Preferably, the spring holder include adjusting bolt to and fix at adjusting bolt bottom and adjusting bolt circumferential direction, axially fixed's connecting block, the bottom and the spring fixed connection of connecting block, the top of shell is seted up with adjusting bolt assorted screw.

Preferably, the bottom of the pressure plate is in the shape of a circular arc with the left and right sides bent downwards.

The arc-shaped pressing plate can increase the contact area with the electric wire, and the wiring strength is improved.

Preferably, the pressing plate is formed by bending a copper sheet.

The copper sheet has better electric conductivity and is not easy to corrode and age.

The utility model has the advantages as follows:

1. the clamping type wiring terminal designed by the spring is simple and quick to operate during wiring, and the efficiency is greatly improved;

2. the pressing plate is pressed upwards through the button, so that the spring can be contracted, two fingers can operate, and the operation is very convenient and labor-saving;

3. the height of the connecting block can be adjusted by the adjusting bolt, so that the pressing force of the adjusting spring when the electric wire is pressed is adjusted, the electric wire with different thicknesses can be suitable, the elastic force of the spring is reduced, the adjusting bolt can be used for adjusting, and the service life of the electric wire is prolonged.

Drawings

Fig. 1 is a schematic longitudinal sectional structure of the present invention;

fig. 2 is a schematic view of the spring when it is contracted.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description of specific embodiments thereof, which is illustrated in the accompanying drawings.

Example 1

As shown in fig. 1-2, a binding post of joint formula, including shell 1, shell 1 be front and back both sides open-ended mouth style of calligraphy, the top inboard of shell 1 is equipped with spring 2, the bottom of spring 2 is fixed with clamp plate 3, clamp plate 3 is fixed with a guide arm 4 respectively in the bottom at four apex angles, guide arm 4 passes the bottom of shell 1 and stretches the below of shell 1, four the bottom mounting of guide arm 4 has button 5, the bottom center of clamp plate 3 is fixed with upper locking block 10, the inboard center in bottom of shell 1 is fixed with lower locking block 6.

The spring 2 is arranged on the top of the shell 1 through a spring seat.

The spring holder include adjusting bolt 7 to and fix in adjusting bolt 7 bottom and 7 circumferential direction of adjusting bolt, axial fixity's connecting block 8, the bottom and the 2 fixed connection of spring of connecting block 8, the top of shell 1 seted up with adjusting bolt 7 assorted screw 9.

The bottom of the pressing plate 3 is in the shape of a circular arc with the left side and the right side bent downwards.

The pressing plate 3 is formed by bending a copper sheet.

The utility model discloses a theory of operation:

under initial condition, spring 2 is the extension state, when needs wiring, presses button 5 for spring 2 contracts, and at this moment, places the connector lug in the below of clamp plate 3, then loosens, and spring 2 is with the connector lug chucking under the effect of restoring force, thereby has accomplished the wiring.

When the clamping force of the spring 2 needs to be adjusted, the adjusting bolt 7 is rotated to enable the connecting block 8 to move up and down, the connecting block 8 moves up, the clamping force of the spring 2 is reduced, the connecting block 8 moves down, and the clamping force of the spring 2 is increased.

Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
