The invention provides a socket connector and a connector combination. The socket connector comprises an insulation body, a plurality of conductive terminals arranged on the insulation body, a metal shell and a slip mechanism. The metal shell is combined with the insulation body and forms a first plug space which accommodates a first plug and an entrance through which the first plug space can be entered into. The slip mechanism is arranged in the metal shell and comprises a slide block and a reset elasticity assembly connected with the slide block. The slide block can slide between a front position which is close to the entrance and a rear position which is far away from the entrance. Because of an effect of the reset elasticity assembly, the slide block is located at the front position in a normal state. The slide block is located at the front position, which means that the slide block is on one side in the first plug space. An inner side surface of the slide block and the metal shell form a second plug space which accommodates a second plug. The slide block can be pushed by the first plug and move to the rear position so as to move out of the first plug space.

The invention discloses a connector. The connector comprises plugs and electric wires, wherein the plugs are connected with the electric wires, at least one plug is a flat plug, and the upper surface or the lower surface of a shell of the at least one flat plug is provided with an identifier which can be identified by touch. The connector disclosed by the invention can be prevented from being inversely inserted under a nonluminous invisible situation.

A plug receptacle includes a housing having at least one outlet unit to which a plug is adapted to be connected to supply a DC power to the plug, and a cable, connected to the housing, for supplying the DC power to the housing. The outlet unit includes a plug- receiving portion having a plurality of substantially circular pin- inserting holes into which plug pins of the plug are inserted and an insertion groove formed to surround a periphery of the plug-receiving portion. The plug- receiving portion has a substantially quadrangular shape viewed from a front side thereof. The insertion groove is adapted to receive a surrounding wall of the plug and has a substantially quadrangular shape viewed from the front side. The pin-receiving holes are arranged along one side of the plug- receiving portion serving as a reference side and offset closer to the reference side than an opposite side to the reference side.

The invention discloses a fool-proof structure for air conditioner electronic control plugging connection. The fool-proof structure for air conditioner electronic control plugging connection comprises an electronic control PCB and a connector, wherein the electronic control PCB is provided with pin ports, the connector is provided with pins, and the pins are plugged in the pin ports; the electronic control PCB is provided with plugging holes beside the pin ports for direction recognition, locating columns are arranged at the positions, corresponding to the plugging holes, of the connector, and the locating columns are plugged in the plugging holes. Compared with the prior art, the fool-proof structure for air conditioner electronic control plugging connection has the advantages that the pins of the connector need to be plugged into the pin ports of the electronic control PCB, besides, the locating columns of the connector are also plugged into the corresponding plugging holes of the electronic control PCB, if the locating columns are not installed in the correct direction of the electronic control PCB, the connector can not be plugged into the electronic control PCB, and therefore the connector can be prevented from being reversely plugged to the electronic control PCB, and damage to air conditioner electronic controls from reverse plugging connection can be avoided.

A multi-connection type header connector, and a stack type socket connector and a horizontal type socket connector for connection thereto A multi-connection type header connector and a stack type socket and a horizontal type socket connectors for connection to the multi-connection type header is disclosed which can accomplish reduction in both the mounting area and the height. The multi-connection type header connector (100) comprises a header housing (110) that is provided with a receiving chamber (115) that concaves from the top face (111) and extends up to an end face (113) on the front side in the depth direction and a header contact (120), of which contacting part (121) is exposed to the receiving chamber (115) and of which connecting part (122) is exposed to the periphery of the bottom face of the header housing (110). A stack type socket connector (200), which has, at one end in the height direction thereof, a protruding part (211) that is to fit into the receiving chamber (115) in the height direction, and from which, at the other end, a wire (W) is led out in a direction that crosses the height direction, and the horizontal type socket contact (300). The horizontal type connector has, at the end on the rear side in the depth direction, a protruding part (311) that fits into the receiving chamber (115) in the height direction, and from which, at the end on the front side in the depth direction, a wire (W) is led out in a direction that crosses the height direction, can be selectively connected to the header connector (100).
