Double-row hole connection adapter
The utility model relates to a kind of termination.
At present, when locomotive electric cad system overhaul of the equipments or electrical equipment malfunction, sometimes need to change electric equipment, need the wiring of electric equipment to remove, very large inconvenience can be brought to inspection and maintenance like this.Meanwhile, when the small area analysis power consumption equipment of the voltages such as many places needs wiring, be generally transferred by a terminal board or connector, but terminal board and connector need to take a large amount of spaces, Costco Wholesale is also very high.
How to solve the problems of the technologies described above and become this those skilled in the art's problem demanding prompt solution.
Utility model content
The purpose of this utility model is just to provide a kind of locomotive electric cad system equipment wiring switching device, difficulty of taking out stitches when solving prior art maintenance of electrical equipment and safeguard, employing terminal board and the technical problem that connector takes up room greatly, cost is high.
The purpose of this utility model is realized by following technical proposals:
A kind of double-row hole connection adapter; comprise protective cover; two rows socket is offered at protective cover end face; the conductive plate be fixed on fixture is provided with in protective cover; the upper and lower two ends of fixture are extended swash plate respectively and are connected with protective cover; corresponding two rows socket offers through hole on swash plate, and arranges the shell fragment for compressing wire core.
As preferably, described front cover body and rear cover body is detachable connects and composes, one end end face of front cover body offers two rows socket, and the other end is not closed, and arranges fixture and conductive plate.
As preferably, described rear cover body is plugged on the non-blind end of front cover body, and rear cover body adopts transparent insulation material to make.
As preferably, described fixture is left end is closed square shape structure, and conductive plate is the untight square shape structure of right-hand member, and the openend of conductive plate inserts in the openend of fixture and is fixed.
Compared with prior art, the beneficial effects of the utility model are:
1. adopt this connection adapter to not only simplify the wiring of electric equipment, and the difficulty of taking out stitches when solving maintenance of electrical equipment and safeguard.
2. this connection adapter structure is simple, reasonable in design, cost is low, and installing space is little, be specially adapted to the wiring of the small area analysis circuit (as lighting circuit, control circuit, microcomputer signal circuit etc.) on locomotive, and need the situation simultaneously connecing several equipotential power consumption equipment.
3. this connection adapter has double socket, can meet the wiring requirement of more equipment, further conserve space.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the A-A cross-sectional view in Fig. 1.
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
Shown in Fig. 1 and Fig. 2, a kind of double-row hole connection adapter, comprises protective cover, fixture 4, conductive plate 2 and shell fragment 3.Protective cover is made up of front cover body 6 and rear cover body 5, and one end end face of front cover body 6 offers two rows socket 7, and the other end is not closed, and rear cover body 5 is plugged on the non-blind end of front cover body 6, and rear cover body 5 adopts transparent insulation material to make.
Fixture 4 for left end be closed square shape structure, conductive plate 2 is the untight square shape structure of right-hand member, and the openend of conductive plate 2 inserts in the openend of fixture 4 and is fixed.
Fixture about 4 two ends are extended swash plate 8 respectively and are connected and fixed with the non-blind end of front cover body 6, and corresponding two rows socket 7 offers through hole on swash plate 8, and shell fragment 3 is fixed on the swash plate 8 outside through hole, for compressing wire core.
In use, insert wire core 1 in socket 7, wire core 1 is compressed by shell fragment 3 through after the through hole on swash plate 8, and with conductive plate 2 close contact, make the wire core 1 inserted up and down connect to form equipotential circuit by conductive plate 2.Rear cover body 5 is detachable with front cover body 6, thus be convenient to check wire core 1 whether with conductive plate 2 reliable contacts, and check whether shell fragment 3 puts in place wire core 1 crimping, and rear cover body 5 also has the effect of dust-proof insulation simultaneously.
This connection adapter has double socket, can meet the wiring requirement of more equipment, further conserve space.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
