Description

  The present invention relates to the structure of the cable connector, mainly composed of upper and lower casings molded in advance, and positioning ribs, conductive pieces and clamping grooves used for clamping and connecting the cables are installed inside the casing according to the number of cables, After inserting the cables to be connected from both sides of the casing, the cables can be easily clamped and fixed by the two casings, and the connection end of the cable and the conductive piece can be safely clamped and fixed, and the cables can be connected easily and safely. The present invention relates to a structure of a cable connector capable of performing the above.

When routing cables, it is necessary to connect the cables based on the actual cable layout, and traditional cable connections, especially those used for energization, are made based on the actual wiring connection needs. As for simple indoor wiring, the connection method shown in Fig. 8 is normally used for cable connection such as extension / connection and branch connection for connecting outlets, switches and lamps or special monitoring devices with cables. Is done. In this method, after the covering portions of the two cables 20 are removed at appropriate positions, the metal connection end portions 21 are exposed for an appropriate length, and the metal wire portions of both connection end portions 21 are removed by hand or pliers. In this method, the twisted end portion 22 is formed by twisting, covered with an insulating cloth 23 from the outside, and then bent from the protruding end portion of the cable 20 to which the mating end portion 22 is connected, and further covered with the insulating cloth 23.
However, in this method, the connection position rises irregularly, and when the cable 20 is connected by this method, all the connection parts rise irregularly in appearance and are very ugly. When the current passes, the mating portion 22 is more concentrated, so that heat concentrates and the electrical resistance increases, and the impedance increases due to the mating portion 22. Furthermore, when the coating is incomplete or the alignment is incomplete, disconnection or electric leakage easily occurs. In addition, the moisture-proof design is not made at all, and there is a risk of electric leakage when immersed. In addition, cable connection is completely left to the skill of connection technology and the certainty of construction quality. Especially, the construction technology of water supply and electric companies is based on experience, so it is difficult to ensure consistent construction quality. There are safety issues and inconvenience. Therefore, how to standardize the cable connection at the time of wiring to reduce the difficulty of construction technology, standardized auxiliary parts can be convenient, simple construction technology, and match the construction quality. Improving connection security is a matter of active industry development research.
