Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to fig. 1 to 5, the connector includes a mounting housing 1, and a connecting mechanism for hidden conduction and compression fastening between electrical components and between the electrical components and a conductive body is covered in the mounting housing 1. The actual use of the connector is schematically illustrated in fig. 5, wherein the electrical accessory is shown as an electrical switch 10 and the electrical conductor is shown as a conductive copper plate 20. The mounting case 1 is placed on a terminal of the electrical switch, and the mounting case 1 is fixed on a substrate 30 on which the electrical switch is mounted through a connection structure (preferably, a brass plate is laid in the substrate for connecting with a main power line and providing a conduction power supply for electrical accessories on the top surface of the substrate), and at the same time, hidden conduction is performed between the electrical switches and the brass plate through the connection structure. The connecting mode solves the defects of conducting between the electrical accessory and the electric conductor through the externally-leaked connecting wire, and can improve the safety and the economical efficiency of electricity utilization.

Specifically, along its length direction seted up through hole 11 in the installation casing 1, coupling mechanism includes through hole 11 one end internal fixation sets up and extends to the outer electrically conductive post section of thick bamboo 2 of installation casing 1, through hole 11 is in the activity is worn to be equipped with and is stretched out in the electrically conductive post section of thick bamboo 2 fastener 3 outside the electrically conductive post section of thick bamboo 2 install 1 one side or the multiple side seted up with through hole 11 perpendicular through-going opening 12 stretch out in the opening 12 to stretch out to have the cover to establish on fastener 3, and pass through fastener 3 compresses tightly the current conducting plate 6 between fastener 3 and electrically conductive post section of thick bamboo 2. The connecting mechanism formed by the components has the following functions: as shown in fig. 5, first, the conductive plate 6 extending out of the opening 12 is inserted into a terminal (shown in fig. 1 a) of the electrical switch, and a tool (e.g., a screwdriver) is inserted into the through hole 11 to apply an external force to the fastening member 3 (preferably, a fastening screw), so that the fastening member 3 and the mounting housing 1 are integrally fastened to a copper plate (preferably, the copper plate is provided with a threaded hole for fastening with the fastening screw), and the bottom end of the conductive cylinder 2 is in contact with and conductive with the surface of the copper plate. The conducting plate 6 is pressed on the top end of the conducting column barrel 2 in the fastening process of the fastening screw, and meanwhile, the part of the conducting plate 6 which is inserted and connected with the conducting plate is pressed through the fastening screw 1b of the terminal of the electric switch, so that the terminal of the copper plate and the terminal of the electric switch are conducted, and a power supply is further provided for the electric switch. Taking this way as an example, if a plurality of electrical switches or accessories need to be connected and conducted at the same time, the plurality of electrical switches and accessories can be conducted simultaneously by installing openings formed in other side walls of the housing 1 and extending the conductive plate 6 body from the corresponding openings and inserting the conductive plate into the corresponding electrical switches and accessories. Therefore, the connection mode of the electric connecting piece can greatly reduce the number of the electric switches and the accessories and the electric conductors connected by the conducting wires, so that the whole electric assembly is more concise and safer, the efficiency and the quality of the electric assembly can be improved, the hidden conduction connection is realized between the conducting plate 6 and the electric accessories and between the electric conductors, the leakage of connection points is avoided, the safety is improved, the risk of electricity stealing can be effectively prevented, and the economy of electricity utilization is improved. Because the current conducting plate 6 is connected with the electric fittings in an inserting connection mode, the electric fittings can be further pressed on the assembly substrate under the fastening action of the fasteners 3 and the electric conductors, the fastening performance of the electric fittings is improved, and the risk that the circuits are out of order due to falling of the electric fittings is avoided.

After the fastener and the mounting shell 1 are integrally fastened on the substrate through the through hole 11, the through hole 11 is closed and hidden through the pressing plate 4, and the terminal of the electric accessory is closed and hidden through the part extending out of the pressing plate 4 (such as a fastening screw of the terminal of an electric switch), so that the leakage of the connection point is avoided, the electricity utilization safety is improved, and the risk of electricity stealing is reduced.

In order to further reduce the risk of electricity stealing, one end of the pressure plate 4 is hinged on the mounting shell 1, the other side wall of the mounting shell 1 opposite to the hinged end is symmetrically provided with a fastening through hole 14 for the pressure plate 4, and the side wall of the pressure plate 4 is provided with a spring pin 5 matched with the fastening through hole 14. After the connecting point of the through hole 11 and the electric switch is sealed and hidden by the pressing plate 4, the closed state of the pressing plate 4 is fastened through the matching of the spring pin 5 and the fastening through hole 14, the difficulty of opening the pressing plate 4 is improved on the premise of not using auxiliary tools, the risk of electricity stealing is further reduced, and the electricity utilization economy is improved. When normal opening is required, the open state of the pressure plate 4 is realized by pushing the spring pin 5 out of the fastening through-hole 14 using a rod-like tool capable of penetrating into the fastening through-hole 14.
