Abstract: A pair of pin press-connecting pliers. The pliers include a first handle and a second handle pivot connected via a connecting seat. The first handle is provided on the inner side thereof with a guiding portion. A first press-connecting portion is provided in the guiding portion, and a linking member connects the first press-connecting portion with the second press-connecting portion. A second press-connecting portion is fixedly provided on the tailing end of the guiding portion via a die block. The connecting seat has at least a concave portion at the press connecting area of the first and the second handles for resting a wire thereon, and has a knife provided on a corresponding handle for peeling or cutting wire in cooperation with the concave portion.

Abstract: A pair of pliers for connecting a telephone line connector. The pliers have a compression connecting block connected with a limiting pin inserted in a limiting hole preferably of a triangular shape on one handle of the pliers. The upper edge of the limiting hole has an abutting edge bevel relative to a push guiding edge of the limiting hole. When the abutting edge contacts and presses the limiting pin, the contact point therebetween is located next to the center of the limiting pin towards the direction of an action force such that the component force of a resisting force from the center of the limiting pin towards the contact point is at the same side as that of the action force. Thus, the horizontal component force of the action force can be reduced; and the abrasion that the horizontal force component may cause on the guiding groove can be reduced.

Abstract: A pair of pliers for compression connecting a connector for a telephone line, the pliers have a compression connecting block connected with a limiting pin inserted in a limiting hole generally of a triangular shape on one handle of the pliers, the upper edge of the limiting hole is an abutting edge bevel relative to a push guiding edge of the limiting hole, when the abutting edge contacts and presses the limiting pin, the contact point between them is located beside the center of the limiting pin toward the direction where an action force directs to. So that the component force of a resisting force from the center of the limiting pin toward the contact point is at the same side as that of the action force. Thereby, the horizontal component force of the action force can be reduced; the abrasion that the horizontal force component may make on the guiding groove can be lowered.

Abstract: A co-axial terminator press fitting pliers, wherein, an insertion opening defined by both inner sides of the linkage plate of the press fit pliers in relation to the other end of the cable jaw is provided to receive insertion by an insertion part defined by both sides of a press fitting block. The connection piece to receive the terminator is mounted through the press fitting block. The press fitting block is held in position on the other end of the linkage plate relatively to the cable jaw when the press fitting block is engaged in the insertion opening of the linkage plate. And the press fitting block is readily replaceable with another type of connection piece for the press fitting pliers to expand its applicability as a whole.
