Abstract

The utility model discloses a mechanical interlocking-type contactor, which contains two contactor units that are arranged in side by side; wherein each contactor unit has a support and a base, while two contactor units are provided with a mechanical interlocking unit; and the base has an empty cavity that can contain the mechanical interlocking unit. As the mechanical interlocking unit is arranged in the empty cavity on the base, thus the mechanical interlocking-type contactor is not to occupy the independent space, so that the whole machine structure after assembling is tight and the volume is small.

Description

A kind of mechanical interlocked contactor device

Technical field

The utility model relates to a kind of low-voltage electrical apparatus, particularly a kind of contactor, specifically a kind of mechanical interlocked contactor device.

Background technology

The existing mechanical interlocked contactor device comprises two contact units that are arranged side by side, and described each contact unit has base and pedestal, is provided with mechanical interlocked unit between two contact units.Two contact units of described mechanical interlocked unit assurance are selected a closure.Because the interlocking unit is contained between the sidewall of two contact units, need take independently space, cause between two contact units distance bigger, the volume of the entire product after the assembling can be bigger.

Summary of the invention

The above-mentioned defective that prior art to be solved in the utility model exists provides a kind of follow-on mechanical interlocked contactor device, is intended to reduce small product size.

The technical scheme that addresses the above problem employing is: a kind of mechanical interlocked contactor device, comprise at least two contact units that are arranged side by side, described each contact unit has base and pedestal, be provided with mechanical interlocked unit between two contact units, described pedestal has the cavity that can hold described mechanical interlocked unit.

Mechanical interlocked contactor device of the present utility model because described mechanical interlocked unit is arranged in the pedestal upper plenum, does not take separate space, thereby the compact integral structure after the assembling, and volume is less.

Described mechanical interlocked unit can be arranged in the cavity of offering on the single pedestal, also can be arranged on by in the involutory big cavity that constitutes of the open type cavity of offering on two pedestals in opposite directions, preferred latter's structure.

As further improvement of the utility model, described mechanical interlocked unit comprises a bracing or strutting arrangement and a pair of mechanical interlocked tumbler that is used for that is coupling on described bracing or strutting arrangement, described each tumbler is provided with an interlocking face, a stop end and the elastic recovery device that can make tumbler remain on first jiao of position, and the displaceable member interlock in each tumbler and the corresponding contact device unit.

Described each tumbler is to realize by the mode that projection matches with groove with displaceable member interlock in the corresponding contact device unit.Described each tumbler is provided with a projection, offers a groove on the displaceable member in the corresponding contact device unit.Vice versa.

Mechanical interlocked contactor device of the present utility model, described each tumbler all has first jiao of position and second jiao of position, two tumblers can be in second jiao of position with being in first jiao of position or selecting one, can guarantee that like this two contactors are not closed simultaneously.

Further improve again as of the present utility model, the rotation axis two ends of described tumbler are separately positioned in the hole of offering on a pair of cavity sidewalls in opposite directions, mechanical interlocked unit can be connected with contactor easily by this simple mode, and be easy to dismounting.

Further improve as of the present utility model, described base is provided with one or more similar T shapes and/or L shaped groove, and two contact units connect side by side by the mode that jockey cooperates with groove.Connect in this way, two mutual cards of contact unit sidewall close, and reach zero spacing splicing-in.

Embodiment

Shown in Figure 1,

contact unit

10a, 10b is linked together side by side, and contact unit is provided with

base

13a, 13b, pedestal 14a, the distance L between the 14b, two contact units approaches zero.

Figure 2 shows that the general configuration of contactor arrangement, can be clear that each parts and connecting relation thereof.Contactor arrangement is made of contact unit 10a, contact unit 10b, mechanical interlocked unit 20 and one or more jockey 33.Pedestal 14a, 14b are provided with

open type cavity

16a, 16b in opposite directions, and the involutory formation of

cavity

16a, 16b can be held the big cavity 16 of mechanical interlocked unit 20, and cavity sidewalls is provided with one or more hole 19a of solid mechanical interlocking unit 20,

19b.Base

13a, 13b are provided with one or

more groove

12a, 12b, and 12a, 12b constitutes the groove 12 that can hold one or more jockeys 33, and one or more jockeys 33 are linked together two contact units.Described jockey 33 is provided with salient point 34, and behind insertion groove 12, salient point 34 can make jockey 33 and groove 12 produce tight fit.

Shown in Fig. 3,4, mechanical interlocked unit 20, comprise a bracing or strutting arrangement 24 and a pair of mechanical interlocked tumbler 21a that is used for that is coupling on described bracing or

strutting arrangement

24,21b, described each

tumbler

21a, 21b is provided with an interlocking

face

27a, 27b, a

stop end

22a, 22b, a protruding 25a, 25b and one can make

tumbler

21a, and 21b remains on the elastic recovery device 26a of first jiao of position, 26b, and each tumbler 21a, the displaceable member 11a in 21b and the corresponding contact device unit, 11b interlock.Among the figure, when tumbler 21a is in second jiao of position,, thereby forbid that tumbler 21b switches to second jiao of position from first jiao of position because stop end 22a withstands face 27b.

Shown in Figure 5, mechanical interlocked contactor, mechanical interlocked unit 20 are located between two contact units that are in release condition, and

tumbler

21a, 21b all are in first jiao of position, protruding 25a, and 25b inserts displaceable member 11a, and the groove 15a of 11b is in the 15b.Fig. 6 is the partial enlarged view of Fig. 5.

Shown in Figure 7, mechanical interlocked contactor interlocking schematic diagram, mechanical interlocked unit 20 are located between two contact units, contact unit 10a is in closure state, tumbler 21a is in second jiao of position, and tumbler 21b is in first jiao of position, and contact unit 10b is in release condition.Fig. 8 is the partial enlarged view of Fig. 7.

Operation principle of the present utility model is as follows: when contact unit 10a is closed, its displaceable member 11a moves downward, the groove 15a of displaceable member 11a side forces the protruding 25a on the tumbler 21a to move downward, and makes tumbler 21a switch to second jiao of position from first jiao of position.When tumbler 21a is in second jiao of position, because residing the 27a of stop end 22a and the stop end 22b of tumbler 21b on the tumbler 21a is relative, thereby forbid that tumbler 21b switches to second jiao of position from first jiao of position, therefore, protruding 25b on the tumbler 21b can forbid the moving downward of displaceable member 11b of contact unit 10b, like this, even contact unit 10b can not be closed under "on" position.In like manner, if contact unit 10b is closed earlier, contact unit 10a just can not be closed, as contact unit 10a, and when 10b all is in release condition, since elastic recovery device 26a, the effect of 26b, and two tumblers all are in first jiao of position.Therefore two contact units guarantee wherein closure,

contact unit

10a, and 10b can not be closed simultaneously.

The utility model has no to be confined to specifically described embodiment signal naturally, but can extension to other some embodiment, therefore can expect and to carry out numerous modifications and variations to contactor arrangement, all modifications and changing all in the scope of utility model design, all details can be with technical identical or equivalent element replacement.Particularly some embodiment signals like this: contact unit 10a, the pedestal 14a of 10b, 14b have the cavity 16 that can hold mechanical interlocked unit 20.
