Penetrating type connector combination

Abstract

The invention discloses a penetrating type connector combination. The combination comprises a main body part and a cable, the cable includes core wires, the main body part comprises a joint, conducting terminals and a pedestal, the pedestal is provided with wire ducts, and the width and depth of the wire ducts match those of the core wires; and the bottom of the wire ducts is provided with connecting terminals which are electrically connected with the conducting terminals; an upper cover is fixed on the pedestal, and includes through holes which are aligned with the wire ducts respectively up and down; and penetrating sheets are inserted downwardly into the through holes, and make contact with the connecting terminals by penetrating the core wires. The penetrating type connector combination has the advantages that the core wires are pressed into the wire ducts and are thus very easy to assemble; the core wires tend not to offset or rotate in the wire ducts due to pressure by the penetrating sheets, and it can be ensured that the penetrating sheets can be inserted in places accurately; and the connecting terminals including positioning holes, the penetrating sheets are inserted into the positioning holes after penetrating the core wires and thus fixed in both up and down, the penetrating sheets cannot be loosened event the cable is drawn by a large force, and the reliability is extremely high.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a connector combination that needs to be connected and fixed with cables through conductive connection terminals. Background technique [0002] With the rapid development of electronic technology, computers and electronic products have been rapidly popularized. Various electronic devices such as mobile phones, cameras, mice, printers, etc. need to realize functions such as charging and data transmission through data cables. Traditional data cables, such as USB data cables, mainly have two connection methods. The first is to fix the cable and the connection terminal by welding; the second is to insert the cable through the piercing part of the connection terminal. achieve fixation. Because the operation process of welding is cumbersome, inefficient, and easy to fall off, it has basically been replaced by piercing. [0003] However, the piercing method currently use...

Because the operation process of welding is cumbersome, inefficient, and easy to fall off, it has basically been replaced by piercing

[0003] However, the piercing method currently used also has obvious defects. For example, Chinese patent CN201781137U discloses a cable connector combination. This technical solution is a widely used connection method at present. Representatively, a hole for accommodating cables is provided on a main body block, the cables are first inserted into the hole, and the connecting terminal with a piercing part is fixed on a cover plate, and then the cover plate and the main body block are connected Fixed, so that the piercing part of the connecting terminal pierces into the cable to contact the metal wire to achieve electrical connection

The disadvantage of this method is that, first, since the cable accommodating space is a hole, the cable needs to be inserted into the hole, which requires that the hole diameter is much larger than the cable diameter, otherwise it will be difficult to insert

Since the hole diameter is larger than that of the cable, and the cable is not specially fixed in the initial state, the cable will rotate and shift when inserted into the piercing part, resulting in incomplete insertion, insufficient contact position, or even Not plugged in, resulting in a high rate of defective products, and even if some products pass the quality inspection, a little force during use will lead to poor contact; However, this kind of insertion operation is still very difficult, especially for small core wires, the efficiency of the insertion operation is very low; third, the piercing part of the connecting terminal is only inserted into the cable without other auxiliary fixation, which is subject to Weaker pulling ability, more prone to fall off
