Abstract
The utility model discloses a medium voltage cabinet aviation plug fixing device comprising a plastic plug and a plastic socket provided with an inserting pin. The opposite corner of one of the plastic plug and the plastic socket, which are combined together, is provided with an installation through hole, and a bolt passing through the installation through hole is connected with a nut in a screwed manner to fix the plastic plug and the plastic socket, which are combined together. The bolt and the nut are made of nylon materials. The medium voltage cabinet aviation plug fixing device is advantageous in that the aviation plug structure can be more stable, the starting/stopping times of the breaker can be reduced, and therefore the stability of the device can be improved, and the service lifetime of the device can be prolonged.
Description
Technical field
The utility model relates to a kind of fastener, refers in particular to the anti-shake fixture that a kind of aviation being applied in middle pressure cabinet is plugged.
Background technology
At present, between the secondary singal circuit of the breaker mechanism in middle pressure cabinet and man-machine interaction panel, be that the interface slot inserting in circuit breaker by aviation is realized communication connection.Aviation is inserted as Communication Control connecting device for line, inserts the groove of breaker body by the slotting contact pin of aviation, can realize the signal transmission between linear quadratic control circuit and middle pressure device.In the time of circuit breaker action or shake, easily there is shake to cause the loose contact of the slotting contact pin of aviation and breaker body, contact pin position is not in place or loosening, affect normal signal transmission, even can make circuit breaker trip in use, affect the normal operation of equipment, the useful life of also greatly having reduced circuit breaker and equipment simultaneously.
Utility model content
For the deficiencies in the prior art part, the utility model provides in one presses cabinet aviation to insert fixture.This fixture makes aviation inserting structure more firm, to reduce the start-stop time of circuit breaker, so that the stability of raising equipment, the useful life of extension device.
For achieving the above object, technical solutions of the utility model are:
Fixture is inserted in the aviation of middle pressure cabinet, and described aviation is inserted and comprised a plastic plug and a plastic socket with contact pin.On the plastic plug of assembled state and plastic socket, correspondence is provided with installation through hole, a bolt that runs through described installation through hole plastic plug and the plastic socket of a nut with further fixed combination state that be spirally connected.
Furtherly, the screw bolt and nut that described screw bolt and nut is nylon material.
Furtherly, described installation through hole is arranged on the plastic plug of assembled state and the wherein pair of horns of plastic socket is locational, so that two groups of screw bolt and nut fixed plastics plug and plastic socket on diagonal position respectively.
The usefulness of technique scheme is:
In the utility model, press cabinet aviation to insert fixture and further reinforce aviation and insert by easy bolt, nut assembly structure are installed, with ensure aviation insert do not come off, with the stable signal transmission of circuit breaker.Bolt, the nut of the nylon material that the utility model adopts, slotting similar, with low cost with the plastic material performance of circuit breaker to aviation, not only self there is very high mechanical strength, wear-resistant; And shock absorption is strong, loosening to prevent contact pin, ensure can not come off in the time of circuit breaker action and shake, circuit breaker is not threatened; Further, the bolt of nylon material, nut assembly structure edge performance are good, prevent that static exerts an influence to contact pin signal.The utility model only need be installed two groups of bolts at the diagonal position of aviation cabinet, nut assembly structure can be avoided the equipment downtime phenomenon causing because of the loosening loose contact of circuit breaker vibrations contact pin, to reduce the use of assembly parts.
Brief description of the drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a part of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the slotting plastic plug structural representation of the utility model aviation;
Fig. 2 is the structural representation of the slotting plastic socket of the utility model aviation;
Fig. 3 is the structural representation that fixture is inserted in the utility model aviation.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Aviation is as shown in Figure 1, 2 inserted and is comprised a plastic plug 10 and a plastic socket 30 with contact pin 20, after plastic socket 30 snapping plastic plugs 10, is plugged on circuit breaker.On plastic plug 10 and plastic socket 30, be respectively arranged with installation through hole, and described installation through hole is that correspondence is arranged on the plastic plug of assembled state and the wherein pair of horns of plastic socket is locational.As shown in Figure 1, be provided with the first plug in the upper right corner of plastic plug 10 through hole 11 is installed, be provided with the second plug in the lower left corner of the plastic plug 10 of diagonal position through hole 12 is installed; Corresponding, be provided with the first socket in the upper left corner of plastic socket 30 as shown in Figure 1 through hole 31 is installed, in diagonal position the lower right corner of plastic socket 30 be provided with the second socket through hole 32 be installed, arrange so that the first plug after plastic socket 30 and plastic plug 10 snapping combinations is installed corresponding the first socket installation through hole 31 of through hole 11, the second plug is installed corresponding the second socket installation through hole 32 of through hole 12 and is arranged.
For making plastic socket 30 and plastic plug 10 after snapping combination further fastening, the utility model is provided with and runs through the bolts and nuts threaded that through hole is installed.Best, as long as two groups of screw bolt and nut are set at the plastic plug 10 of snapping assembled state and the diagonal position of plastic socket 30, to reduce the use of assembly parts.Namely, on one, bolt 41 runs through the first plug installation through hole 11 and the first socket installation through hole 31, be spirally connected with a top nut 51, once bolt 42 runs through the second plug installation through hole 12 and the second socket installation through hole 32, be spirally connected with a lower nut 52, so that these two groups of screw bolt and nut fixed plastics plug 10 and plastic socket 30 on diagonal position respectively.
Bolt of the present utility model, nut adopt to aviation and insert the nylon material similar with the plastic material performance of circuit breaker, with low cost.Utilize excellent abrasive resistance, shock absorption and the insulation property of nylon material, ensure that the snapping of plastic plug 10 and plastic socket 30 is firm, to avoid shaking because of circuit breaker the loose contact problem of bringing, improve the stability of equipment.
Above-mentioned explanation illustrates and has described preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in utility model contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection range of the utility model claims.
