Description

Crimping pliers

This creation is about a crimping pliers for a multi-wire terminal block, especially a crimping pliers that can cut the wires protruding outside the multi-line terminal block steadily and without leaving burrs.

At present, the multi-wire terminal block that uses signal connection line, such as the RJ-45 type terminal block used to transmit signals, must be aligned and pressed into the terminal clamping hole of a multi-wire terminal block during installation. Each wire is electrically connected to the terminal in the terminal clamping cavity for the transmission of electronic signals. In order to carry out the installation process quickly, the creator of this author has introduced a multi-wire terminal block crimping pliers as disclosed in my country's patent certificate No. M475085, which can perform the steps of crimping and cutting at the same time, but the components are more complicated.

And because the wires are usually elastic, if the blades of the crimping pliers are worn and not sharp enough when cutting the wires, they will not be able to cut the wires cleanly and will leave burrs or even cut the wires completely. Frequent replacement of the blades is also possible. It does not meet the time and economic benefits, so there is still room for improvement.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a crimping tool to improve the lack of the above-mentioned conventional technology.

The main purpose of this creation is to provide a crimping pliers. There are two anvils for each wire protruding from the multi-wire terminal block to lean against. The blade can cut each wire stably and neatly when cutting the wire, and simplify the structure.

To achieve the above purpose, the crimping tool of this creation includes a base, and a terminal base fixture is combined at the top end. The terminal base fixture is used for socketing a multi-wire terminal base. The terminal base fixture includes two knife anvils, each The knife and anvil parts are oppositely arranged on both sides of the terminal base fixture; a first handle whose top end is pivoted on one side of the base; a second handle whose top end is pivoted on the other side of the base; a sliding seat , Which respectively pivotally connect the middle section of the first handle and the second handle with a connecting rod, so that when the first handle and the second handle are relatively combined, the sliding seat can slide upward in linkage; two elastic elements are respectively provided on the base and Between the first handle and the second handle, the first handle and the second handle are preset to be relatively open; and

A pressing seat, which is locked on the sliding seat so that the pressing seat moves with the sliding seat, the pressing seat includes: a sliding rod, the bottom end of which is locked to the top surface of the sliding seat; a pressing frame, which is slidably arranged on the sliding rod On the periphery, there are two side frame walls; a spring, which is sleeved on the sliding rod, makes the spring support between the pressing frame and the sliding seat; a knife seat, which contains a bottom and radially protruding from the front and rear ends of the bottom Two side walls, the bottom of the knife holder is pivotally connected to the top of the slide bar, the knife holder is located above the pressing frame, so that each side frame wall and each side wall are perpendicular to each other; two blades, each blade is set on the inner side of each side wall of the knife holder; and At least one wire pressing piece straddles the knife base. When the pressing base rises with the sliding base, the pressing frame is pressed on the multi-wire terminal base to stabilize the positioning of the multi-wire terminal base. When the sliding base continues to rise, the knife base It also continues to rise with the push of the sliding rod, so that the wire pressing piece is pressed into the multi-wire terminal base in a correct manner, and each blade moves along the outer edge of the multi-wire terminal base, cutting off the protruding multi-wire terminal base and leaning against each knife anvil Department of the wires.

The inner side of each side wall can be respectively provided with a protruding pin part to penetrate into one of the holes of each blade. The wire pressing piece can have a plurality of protrusions, so that the wire pressing piece can be aligned with the terminal clamping holes in parallel.

Each elastic element can be a torsion spring, one end of each elastic element is respectively arranged on both sides of the base, and the other end of each elastic element leans against the inner side of the first handle or the second handle respectively.

The bottom section of the sliding rod of the pressing seat can form a screw section to be locked to the sliding base, and a compression nut is locked to the screw section, and a linkage groove is recessed on the bottom end surface of the sliding rod. The user can adjust the position of the knife holder relative to the multi-wire terminal holder by adjusting the position of the knife holder relative to the multi-wire terminal holder to adjust the wire pressure by extending the screwdriver into the linkage groove and rotating the slide bar by loosening the tightening nut. The distance of each wire pushed by the chip and the cutting depth of each blade.

The number of wire pressing pieces can be two, and each wire pressing piece is separated by a pressing piece positioning member, so that each wire pressing piece can be respectively aligned with the terminal clamping holes arranged on the same line on the multi-wire terminal block; The conductor pressing pieces can be arranged in parallel between the two side walls of the knife holder. The sheet-pressing positioning member may include a body, and a shoulder is formed on both sides of the main body to abut one of the wire pressing sheets respectively, and at both ends of the main body, a protruding shaft portion axially protrudes to One of the wire pressing pieces located in the lateral direction is respectively pierced. A spacer block can be arranged between each shoulder and each wire pressing piece, and the protruding shaft part penetrates the spacer block.

This creation can not only perform crimping and thread cutting operations at the same time, by setting two anvils, each wire can lean against each knife anvil when cutting, so that each wire protruding from the multi-wire terminal block can be cut firmly and neatly by the blade Off. And use a torsion spring to expand the first handle and the second handle, reducing the number of components and manufacturing costs.

In order to be able to clearly and fully expose the creation, a preferred implementation example is listed to illustrate its implementation in detail as follows.
