Detailed description of the invention

Applicant will describe in detail detailed description of the invention of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, anyly changes in the form rather than substance and all should be considered as protection domain of the present utility model according to the utility model design.

Refer to Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the utility model relates to a kind of checkout gear of breaker body position signalling, and breaker comprises breaker body 1 and drawout chassis 2. Drawout chassis 2 can be put into or take out to breaker body 1, and in the time that breaker body 1 enters or exits drawout chassis 2, according to the structure of breaker itself, it has " connection ", " test ", " separation " these three kinds of duties. When breaker body 1 is during in any one position, need it to send corresponding position signalling and meet need of work. On drawout chassis 2, be provided with the drawout chassis side plate 21 that is positioned at both sides, on described drawout chassis side plate 21, position signal module 211 be installed. Concrete, position signal module 211 is secured on drawout chassis side plate 21 by the mode of clamping, and certainly, if adopt other fixed forms, the common mode such as be for example threaded is also feasible. Described position signal module 211 comprises shell 2112 and cover plate 2113, forms a cavity between the two, and multiple microswitches 2114 are installed in described cavity. Also be provided with an open slot 2115 in the centre of shell 2112. The button of described microswitch 2114 is all positioned at the groove edge of open slot 2115, and stretches into described open slot 2115. Described cover plate 2113 is provided with the holding division 2111 for fixing, and described holding division 2111 comprises the first screens end 21111, the second screens end 21112 and elastic card bit architecture 21113. Accordingly, have the auxiliary section 212 of fixing on described drawout chassis side plate 21, described fixing auxiliary section 212 comprises that the first fixing chamber 2122 and second fixes chamber 2121. The first described screens end 21111 coordinates with the first described fixing chamber 2122, the second described screens end 21112 and elastic card bit architecture 21113 coordinate with the second described fixing chamber 2121, the first described fixing chamber 2122 is T shape chamber, it comprises the first embedding chamber 21221 and the first positioning chamber 21222, the T shape structure that the first described screens end 21111 is outwardly convex, it has near cover plate 2113 sides the groove narrowing. When installation, first the first screens end 21111 is embedded in the first embedding chamber 21221, then first screens end 21111 to first positioning chambers 21222 that slide, now the first screens end 21111 cannot be from taking out perpendicular to the direction of drawout chassis side plate 21. Same, the second described fixing chamber 2121 is T shape chamber, it comprises the second embedding chamber 21211 and the second positioning chamber 21212, and the T shape structure that the second described screens end 21112 is outwardly convex, it has near cover plate 2113 sides the groove narrowing. When installation, first the second screens end 21112 is embedded in the second embedding chamber 21211, then second screens end 21112 to second positioning chambers 21212 that slide, now the second screens end 21112 cannot be from taking out perpendicular to the direction of drawout chassis side plate 21. Because the first above-mentioned screens end 21111 and the second screens end 21112 are all positioned on same cover plate 2113, when installation, be synchronous installation. Described elastic card bit architecture 21113 skids off above-mentioned fixed structure for preventing described the first screens end 21111 and the second screens end 21112 in side plate direction, after being in place, described elastic card bit architecture 21113 is resisted against on the second embedding chamber 21211, thus 211 installations of above-mentioned position signal module. In the time that needs are dismantled, only need to remove above-mentioned elastic card bit architecture 21113 against, can extracting position signaling module 211.

Refer to Fig. 4, breaker body 1 has base shell 12, common, and described base shell 12 comprises pedestal and base plate, by forming after both laminatings. On described base shell 12, be provided with signal location trigger end 121, described signal location trigger end 121 protrudes from base shell 12, and itself and base shell 121 are made into integration. Described be made into integration that to refer to that both pass through thermoplastic processes one-body molded. Described signal location trigger end 121 is for coordinating with described position signal module 211, be that signal location trigger end 121 triggers the microswitch 2114 in described position signal module 211 along with the movement of breaker body 1, thereby position signal module 211 is sent position signalling. Concrete, the button that described signal location trigger end 121 triggers on microswitch 2114 completes trigger action. Because described signal location trigger end 121 is positioned on base shell 12 and is integrated, avoid the error of bringing because of the independent installation site of needs signal trigger end 121 in prior art, spatially save the thickness of side plate simultaneously, therefore, this technical scheme precision is high, and has dwindled the volume of breaker.

Further optimize and be described signal location trigger end 121 to be adjusted into arc-shaped surface or gore etc. at the opposite face 1211 near position signal module 211 sides, make signal location trigger end 121 can there is guide effect in the time of the signaling module 211 of in-position, thereby avoided the shock bringing due to mismatch error.

Further improve and be, described breaker body 1 has caveli 13, and described signal location trigger end 121 is positioned at caveli 13, thereby can further dwindle the width of breaker body 1.
