Description

Improved structure of wire connection terminal

Technical Field

The present invention relates to an improved structure of a wire connection terminal, and more particularly, to a wire connection terminal structure with improved structural strength, precise and stable guiding function, and labor-saving operation.

Background

In chinese patent publication CN 111386631a connection device for connecting conductor ends is disclosed, which mainly comprises: a housing, a bus section disposed in the housing, a clamping spring device, a torsion bar arrangement; the surface of the shell is at least provided with two insertion holes into which the end parts of the wires can extend, symmetrical sliding grooves are respectively arranged at the sides of the two insertion holes, the torsion bar device is pivoted at the sides of the sliding grooves, a control bending part is convexly arranged at the periphery of the torsion bar device, a pin is arranged on the control bending part and can extend into the sliding grooves of the shell to move, the bus section is arranged between the two insertion holes, two sides of the bus section are respectively provided with the sliding grooves with opposite openings, the two sliding grooves respectively overlapped at the end parts of the two sliding grooves of the shell close to the outer side, the opening sides of the two sliding grooves of the bus section are respectively provided with narrowest parts, the clamping spring device is pivoted between the sliding grooves of the shell and the insertion holes through a spring bracket, the clamping spring device is provided with a plurality of leaf springs, and the two end parts of each leaf spring are respectively provided with a control leg close to the torsion bar device and a clamping leg close to the insertion hole; when the wire end extends into two sides of the bus section from the insertion opening, the torsion bar device is pivoted to drive the pin to move, so that the pin moves along the sliding groove of the shell towards the rotating axis close to the spring bracket, and meanwhile, the torsion bar device presses the control support leg at one end of the plate spring through the control bending part to drive the clamping support leg at the other end of the plate spring to press against the wire end, so that the wire end is tightly contacted with two sides of the bus section, and meanwhile, the pin can be embedded into the sliding groove of the bus section and blocked by the narrowest part of the pin to be kept in position, and further, the two wire end can be enabled to be mutually conducted through the bus section.

However, such a structure as described above has the following drawbacks in application: firstly, the structure is limited by the internal space structure state of the shell, the chute structure for guiding the pin only slightly protrudes out of the inner wall of the shell, so that not only the difficulty in shape design and production of the shell is increased, but also the shell is made of plastic materials, and the chute part is difficult to have better structural strength, so that after the abrasion caused by improper operation or long-term use, unsmooth movement or damage is easy to occur, and the torsion bar device cannot normally pivot or accurately and stably drive the clamping spring device to prop against the end part of the lead, and the like; in addition, the torsion bar device drives the clamping spring device to clamp the end part of the wire, the action path of the pin gradually approaches the rotation axis of the spring bracket, so that the control bending part props against the control supporting leg to gradually shorten the arm of force for pivoting the plate spring, so that the force is required to be gradually increased in operation, and when the clamping supporting leg props against the end part of the wire, elastic reaction force is generated on the plate spring, so that the operation of the torsion bar device is more laborious, and inconvenience and defects in application are formed.

In addition, in the inventions of chinese patent publications CN 111406347a and CN 111466057a, connection devices having the same structural features are also disclosed, and obviously the connection devices have the same application drawbacks, which are not described in detail herein.

Since the structure of the prior art conductor-end connection device (wire connection terminal) has the above-mentioned drawbacks in practical use, the inventors have studied improvements against these drawbacks, and have finally produced the present invention.
