The pin and the jack are general technologies in the field as electrical contacts for mating, and for each pin or jack, a fast plug line structure is provided in this embodiment for fast and reliably achieving electrical connection between the pin or jack and an external wire, taking the first pin 111 as an example, the first pin 111 is electrically and fixedly connected to the first wire holder 113, a resilient tab 114 is fixedly provided on one side of the first wire holder 113, a resilient arm of the resilient tab 114 is disposed in a direction deviating toward the first wire holder 113, and when a wire is inserted into the first wire holder 113, the resilient arm of the resilient tab 114 pushes the wire to make full contact with the first wire holder 113. And a movable switch element 115 is disposed at one side of the elastic sheet 114, the switch element 115 can press the elastic arm of the elastic sheet 114 to relatively separate from the first wire holder 113 through its movement, so as to unlock the wire and the first wire holder 113, in this embodiment, the switch element 115 is a sliding push button.

As shown in fig. 2, when the male plug assembly 11 and the female plug assembly 12 are separated, the spring 126 forces the shorting member 125 to electrically connect with the second wire holder 123 and the third wire holder 124 at the same time, thereby shorting the first jack 121 and the second jack 122. As shown in fig. 3, the male plug assembly 11 includes an insulating push rod 116 extending along the mating direction of the male pin and the female plug assembly 12, when the male plug assembly 11 and the female plug assembly 12 perform the mating stroke, the insulating push rod 116 faces the short piece 125 so as to push the short piece 125 away from the first jack 121 and the second jack 122, the short circuit state of the first jack 121 and the second jack 122 is released, and the spring 126 is pushed to store energy to provide a reset force for the short piece 125 when the male plug assembly 11 and the female plug assembly 12 are separated.

In other embodiments, the shorting member 125 may also be in direct electrical contact with the first and second sockets 121, 122, as well as acting on the second and third wire holders 123, 124.

The spring 126 may be replaced by other elastic elements, such as a compression spring in this embodiment, or a pull spring, a spring plate, etc. in other embodiments.

In this embodiment, the short-circuit element 125 is a rectangular block structure, so as to facilitate the manufacture and installation thereof, and the rectangular block-shaped short-circuit element 125 has a flat and large-area abutting surface, a spring 126, a second wire holder 123, and a third wire holder 124 for cooperation. Of course, the first short-piece 125 may have other configurations in other embodiments, as long as the same function is satisfied.

Referring again to fig. 1, in this embodiment, the side wall of the mounting chamber 120 is provided with a window 128 communicating with the outside of the connector unit, and the short piece 125 is allowed to communicate with the outside through the window 128, rather than being closed. When more than two connector units are spliced together, the corresponding position windows 128 are also engaged in alignment so that the shorts 125 in different connector units can be set to a synchronized linkage. Referring specifically to fig. 4-7, to further illustrate the function of the first window 128, this embodiment shows a structural schematic diagram of a connector in which two connector units having the same structure are spliced to form a two-pole loop control connector, and for convenience of distinction, the two connector units are respectively denoted as a first connector unit 1 and a second connector unit 2, the first connector unit 1 includes a first mounting cavity 120A, a first shorting block 125A and a first window 128A, the second connector unit 2 includes a second mounting cavity 120B, a second shorting block 125B and a second window 128B, when the first connector unit 1 and the second connector unit 2 are spliced, the first window 128A and the second window 128B at corresponding positions enable the first mounting cavity 120A and the second mounting cavity 120B to be communicated, and the first shorting block 125A and the second shorting block 125B are fixedly connected by the intermediate connecting member 100 to form an integral body, so that one of the first shorting block 125A and the second shorting block 125B is connected, and the other is triggered. By such an arrangement, the action of the short-circuit element in one loop can synchronously trigger the action of the other short-circuit element, so that the first connector unit 1 and the second connector unit 2 are mutually short-circuited. Of course, if it is not necessary to set the two loops to be synchronously shorted, the first short-circuit member 125A and the second short-circuit member 125B may be independent from each other and unconnected, which is also one of the optional setting schemes. This embodiment sets up to the intercommunication through setting up first installation cavity 120A and second installation cavity 120B, consequently locate a plurality of in the installation cavity of intercommunication the short circuit spare can enough be enough each other independently set up, can link in step-by-step again, has improved the flexibility that the short circuit spare set up.

The connector units may be arranged side by side in at least two groups, and because of the identical structure, the shorting blocks 125 and the mounting cavities 120 of two adjacent connector units are also arranged adjacent to each other. When the connector is a plurality of connector units, the mounting cavities 120 of all the connector units may be set to be connected (for the sandwiched connector units, the windows 128 are set to be one on each of the two pairs of side walls of the mounting cavities 120), or the mounting cavities 120 of some connector units may be selected to be connected, which further increases the flexibility of selection. The short pieces 125 can be selected to be independent or linked according to actual needs. The connector units are modularized and spliced in cooperation, so that the flexibility of assembling multiple groups of actual products and the selectivity of the connector units synchronously short-circuited are greatly improved.

More preferably, the coupling of the plurality of stubs 125 provided in the communicating installation cavities 120 may be provided to be separable. For example, in the first connector unit 1 and the second connector unit 2, the first short-circuit member 125A and the second short-circuit member 125B are both adhesively fixed to the intermediate connector 100 to form a non-detachable integral member, but in other embodiments, the first short-circuit member 125A and the second short-circuit member 125B are both connected to the intermediate connector 100 in an insertion fit manner, so that the connection between the first short-circuit member 125A and the second short-circuit member 125B can be released, and the first short-circuit member 125A and the second short-circuit member 125B can be connected to each other as a whole, or can be separated to be independent from each other, and there is no need to additionally provide short-circuit members of a specific specification, such as three or four short-circuit members fixed to each other in a row.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
