Technical field

The utility model relates to electric clamping connector or elastomeric connector, relates in particular to the screens structure that two above plugs can be inserted the plug body of a common socket itself.

Background technology

In the prior art, for the plug of one 20 pin and a plurality of 4 pins or the plug more than 4 pins are combined, the common insertion among the socket greater than 20 number of pins, U.S. Pat 2005202726 discloses the technical scheme of a kind of " COUPLER DEVICE FOR POWERSUPPLY FACILITY " by name, as shown in Figure 1, this scheme is to the effect that: a kind of removable power supply connecting device that closes, comprise the power supply main body, an and main connector 31, cable by the band elastic contact chip between described power supply main body and the main connector 31 connects, also comprise more than one auxilliary connector, also connect between described power supply main body and the auxilliary connector by the cable of being with elastic contact chip, 31 1 sides of described main connector have wedge shape raised line 34, the auxilliary corresponding side of connector has wedge-shaped impression 40, two connectors are by wedge shape slot 34,40 suitable insert groups lump together, and can not deviate from direction of insertion, these two connectors can be inserted in respectively on 20 pin and the 4 pin sockets, also can combine and be inserted on one 24 pin socket, can also make up more auxilliary connector, be plugged on the socket of more than one pin, after connector after the combination is inserted on the socket, by the buckle between main connector 31 and socket both are locked, related all auxilliary connectors are also locked, can not come off because of external force.

By analyzing as can be seen, it is complicated that the structure of this scheme still shows.

Summary of the invention

The purpose of this utility model is to provide a kind of more easy design, first plug and subordinate plug are inserted after the common socket, buckle between first plug and the socket locks both, the related subordinate plug of fixture block by the protrusion edge of first plug and subordinate plug is also locked, can not come off because of external force.

The utility model is realized by adopting following technical scheme:

Manufacture and design a kind of readily removable power connector that closes, comprising: a kind of readily removable power connector that closes comprises: a main casing, first plug that is connected with described main casing by first cable group with a plurality of elastic contact chips; The subordinate plug that at least one is connected with described main casing by the subordinate cable group with a plurality of elastic contact chips; One can hold the socket of first plug, at least one subordinate plug insertion.

Described first plug is having the protrusion edge near subordinate plug part, and described subordinate plug has the fixture block that stretches out closing on first plug direction, described fixture block be stuck in protrude along under

Described first plug and subordinate plug all equal greater than 4 pins, most typical 20 pin and 4 pin of being respectively.Certainly, this kind design can extend in the middle of the connector of other specifications.

Described first plug is that front and back all has the protrusion edge near subordinate plug part the edge of protrusion being arranged.

Described subordinate plug has the fixture block that stretches out closing on first plug direction, is that front and back all has fixture block.

Compared with prior art, the utility model inserts first plug and subordinate plug after the one common socket, buckle between first plug and the socket locks both, and is also locked by the related subordinate plug of fixture block of the protrusion edge of first plug and subordinate plug, can not come off because of external force.The utility model can adapt to the use of different cultivars computer, and the utility model handling ease, and is with low cost.

Embodiment

Below in conjunction with each embodiment shown in the drawings the utility model is done further detailed description:

With reference to Fig. 2～Fig. 5, manufacture and design a kind of readily removable power connector that closes, comprising: first plug 20 that a main casing 60, is connected with described main casing 60 by first cable group 25 with a plurality of elastic contact chips; The one subordinate plug 30 that is connected with described main casing 60 by subordinate cable group 35 with a plurality of elastic contact chips; One can hold the socket 10 of

first plug

20,30 insertions of subordinate plug.

As shown in Figure 2,, can copy the connected mode between first plug 20 and the subordinate plug 30, be connected outside the subordinate plug 30 if there is more subordinate plug to participate in connecting.

As Fig. 2～4, described first plug 20 is having protrusion along 27 near subordinate plug 30 parts, and described subordinate plug 30 has the fixture block 37 that stretches out closing on first plug, 20 directions, and described fixture block 37 is stuck in protrusion along under 27

Described first plug 20 and subordinate plug 30 all equal greater than 4 pins, most typical 20 pin and 4 pin of being respectively.Certainly, this kind design can extend in the middle of the connector of other specifications.

Described first plug 20 is that front and back all has protrusion along 27 near subordinate plug 30 parts protrusion being arranged along 27.

Described subordinate plug 30 has the fixture block 37 that stretches out closing on first plug, 20 directions, is that front and back all has fixture block 37.

As Fig. 2～Fig. 4, first kind of using method is that subordinate plug 30 is inserted socket 10 earlier, and then first plug 20 is inserted socket 10, and dop 21 snaps in buckle 11.This moment, first plug 20 was by protruding the fixture block 37 of pushing down subordinate plug 30 along 27, and subordinate plug 30 can not be come off, and this method is applicable to the occasion of 24 pin.

Second kind of using method is not need to make up subordinate plug 30, only uses the occasion of 20 pin sockets.Only insert socket 10 with first plug 20 and get final product this moment.

Also have a kind of execution mode: described first plug 20 and subordinate plug 30 all are provided with dop.This kind plug both can be used in must be with the occasion of both combinations, also can be used in the occasion that both must be separated, has the relevant position of socket 10 of subordinate plug 30 correspondences of dop to be provided with buckle.

As shown in Figure 5, socket 10 is connected on the circuit board 40, and described circuit board 40 can be the mainboard of computer or the circuit board of other equipment.

Facts have proved, the utility model inserts first plug and subordinate plug after the one common socket, buckle between first plug and the socket locks both, and is also locked by the related subordinate plug of fixture block of the protrusion edge of first plug and subordinate plug, can not come off because of external force.The utility model can adapt to the use of different cultivars computer, and the utility model handling ease, and is with low cost.

Scheme of the present utility model only is not fit to two plugs, can also expand to more multitapped combination, not only is limited in 20 pin, 4 pin connector categories yet.The design that all and the utility model structure duplicate all should be considered as dropping within the protection range of the present utility model.
