The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

As a preferred embodiment of the present invention, a modular anti-open circuit connector is provided, the modular anti-open circuit connector includes a connector unit as shown in Figure 1, the connector unit is a modular splicable structure, that is, a The connector unit is a module with complete independent functions, and several of the connector units can be spliced into multiple groups. Specifically, a buckle connection structure, a screw connection structure, etc. may be provided on the connector unit to realize splicing of multiple connector units. A connector unit corresponds to a circuit, as shown in Figure 1-3, a connector unit includes a male plug assembly 11 and a female plug assembly 12, and the male plug assembly 11 includes a pair of pins: the first pin 111 and the second pin 112 ; The female plug assembly 12 includes a pair of jacks: the first jack 121 and the second jack 122, the male plug assembly 11 and the female plug assembly 12 can be electrically disconnected by two or two pairs of pins and jacks. The connection is made or broken. It is a common technology in this field that pins and sockets are mated electrical contacts. For each pin or socket, a quick-plug wiring structure is provided in this embodiment for fast and reliable realization of pins or sockets. For the electrical connection between the socket and the external wire, take the first pin 111 as an example, the first pin 111 is fixedly electrically connected to the first terminal block 113, and a shrapnel 114 is fixed on one side of the first terminal block 113, An elastic arm of the elastic sheet 114 is arranged in a direction of deflection toward the first terminal block 113. When the wire is inserted into the first terminal block 113, the elastic arm of the elastic sheet 114 pushes the wire to make it fully contact with the first terminal block 113. touch. And a movable switch part 115 is arranged on one side of the elastic piece 114, and the switch part 115 can move against the elastic arm of the elastic piece 114 to make it relatively away from the first terminal block 113, so that the wire and the first terminal block 113 are unlocked , the switch member 115 in this embodiment is a sliding push button. Similar to the first wire socket 113 of the first pin 111, the first socket 121 is configured with a second wire socket 123 electrically connected thereto, and the second socket 122 is configured with a third wire socket 124 electrically connected thereto. .

A mounting cavity 120 is provided in the female plug assembly 12, and a shorting piece 125 is slidably arranged in the mounting cavity 120 in the direction of inserting the pin and the socket, and a spring 126 applies force to the shorting piece 125 to close the shorting piece. The connector 125 abuts against the second wire socket 123 and the third wire socket 124 . As shown in Figure 2, when the male plug assembly 11 and the female plug assembly 12 are separated, the spring 126 exerts force on the shorting piece 125 so that it is electrically connected to the second terminal block 123 and the third terminal block 124 at the same time, thereby connecting the first socket 121 and the second jack 122 are shorted. As shown in Fig. 3 , the male plug assembly 11 includes an insulating push rod 116 extending along the mating direction of the pin and the socket. Facing the shorting piece 125 so that the shorting piece 125 can be pushed 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 at the same time Energy is stored to provide a reset force for the short-connector 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 socket 121 and the second socket 122 , which is the same as acting on the second wire socket 123 and the third wire socket 124 .

The spring 126 can be replaced by other elastic elements. In this embodiment, it is a compression spring, and in other embodiments, it can also be a tension spring, a shrapnel, and the like.

In this embodiment, the main body of the shorting piece 125 has a rectangular block structure to facilitate its manufacture and installation, and the rectangular shorting piece 125 has a relatively flat, large-area abutment surface and a spring 126 and a second The wire socket 123 and the third wire socket 124 cooperate. Of course, in other embodiments, the first shorting member 125 may also have other configurations, as long as the same function can be satisfied.

The length of the insulating push rod 116 affects the timing of the movement of the short-circuit member 125, so its length can be preferably configured to push the short-connector 125 after the pin and the socket have been in electrical contact, so as to ensure that the short-circuit member 125 is inserted when the short circuit is released. The pins and sockets have been securely mated and in contact.

Referring again to FIG. 1 , in this embodiment, the side wall of the installation cavity 120 is provided with a window 128 leading to the outside of the connector unit, through which the shorting member 125 can communicate with the outside world instead of being closed . When two or more connector units are spliced together, the corresponding position windows 128 are also engaged in alignment, so that the shorting members 125 in different connector units can be set to be connected in synchronous linkage. Specifically referring to Figures 4-7, in order to further illustrate the function of the first window 128, this embodiment shows a schematic structural diagram of splicing two above-mentioned connector units with the same structure into a connector for controlling a bipolar circuit. For the convenience of distinction, The two connector units are marked as a first connector unit 1 and a second connector unit 2 respectively, the first connector unit 1 includes a first installation cavity 120A, a first shorting block 125A and a first window 128A, the second connection The connector unit 2 includes a second installation 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 together, the corresponding positions of the first window 128A and the second window 128B The joint makes the first installation cavity 120A and the second installation cavity 120B communicated, and the first shorting block 125A and the second shorting block 125B are fixedly connected through the intermediate connector 100 to form a whole, so the first shorting When one of the component 125A and the second short-connecting component 125B is touched, the other one is also linked accordingly. By setting in this way, the action of the shorting piece in one circuit can trigger the action of the other shorting piece synchronously, so as to realize mutual short-circuiting of the first connector unit 1 and the second connector unit 2 . Of course, if it is not necessary to set the two circuits to be shorted synchronously, the first shorting member 125A and the second shorting member 125B may also be independent of each other and not connected, which is also one of the optional arrangements. In this embodiment, the first installation cavity 120A and the second installation cavity 120B are set to be in communication, so the multiple short-connectors in the connected installation cavity can be set independently of each other, and can also be linked synchronously. , which improves the flexibility of the setting of the shorting piece.

There may be at least two groups of connector units arranged side by side. Since these connector units have the same structure, the shorting block 125 and the installation cavity 120 of two adjacent connector units are also arranged adjacently. When the connector is a plurality of connector units spliced into groups, the installation cavities 120 of all the connector units can be set to communicate (for the clamped connector unit, its window 128 is set at the two sides of the installation cavity 120 There is one for each side wall), or the installation cavities 120 of certain several connector units are selected to be connected, which further improves the optional flexibility. The shorting member 125 can be selected to be independent or linked according to actual needs. The connector unit matched with this implementation is modular and splicable, so the flexibility of multi-group assembly of the actual product and the selectivity of the connector unit for synchronous short-circuiting have been greatly improved.

More preferably, the coupling of the plurality of shorting pieces 125 disposed in the communicating installation cavity 120 can be set to be detachable. For example, in the above-mentioned first connector unit 1 and second connector unit 2, the first shorting piece 125A and the second shorting piece 125B are bonded and fixed with the intermediate connecting piece 100 to form a non-detachable integral member, but In other embodiments, both the first shorting piece 125A and the second shorting piece 125B can be plugged and connected with the intermediate connecting piece 100, so that the connection between the first shorting piece 125A and the second shorting piece 125B can be disassembled. Then the first short-connector 125A and the second short-connector 125B can be connected as a whole, or can be separated and independent of each other, and there is no need to additionally provide specific specifications such as three or four short-connectors fixed to each other in a row.

Although the present utility model has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that, without departing from the spirit and scope of the present utility model defined by the appended claims, changes in form and details have been made to the present utility model. Various changes made by the utility model all fall into the protection scope of the utility model.
