Abstract
The utility model discloses a time relay which comprises a shell, a cover, an upper plug-in assembly, and a wiring board assembly. The utility model is characterized in that the upper plug-in assembly and the wiring board assembly are both fixed with the shell, and the cover is buckle-fastenedly engaged with the shell. The upper plug-in assembly is provided with a plurality of ears, and is engaged with notches which are shaped by stay hooks arranged on the bottom of the shell. The stay hook is an elastic body, a plurality of sheds are arranged on the corresponding part of the hook stays and the bottom of the shell. Bosses are arranged on rear ends of the ears, and the ears are separately corresponding with the sheds. Due to that the upper plug-in assembly is directly fixed with the shell, the utility model can stop the upper plug-in assembly releasing or breaching from the shell, and due to that the upper plug-in assembly is relatively separated from the wiring board, the counteracting force can not be transmitted to the wiring board when the upper plug-in assembly is engaged with the shell, which effectively prevents the occurence of a dislocation between a nixie display and a viewfinder on the shell.
Description
Technical field
The utility model relates to a kind of time relay.
Background technology
The existing time relay comprises shell, lid, goes up connector assembly and circuit board module, described circuit board module is be arranged in parallel by the polylith wiring board and constitutes, connect with the fastening mode of nut after passing support pipe between corresponding component and parts successively by long spiro nail between last plug-in unit and the polylith wiring board, insert in the cylindrical outer casing connecting good assembly, a wiring board is foremost fixed by the bead of screw and cover top portion, to cover by the buckle mode then and be fixed on the shell, and it is relative with the form that covers to guarantee to be arranged on the demonstration sign indicating number pipe of wiring board.The time relay of this structure has following defective:
One, owing to do not have fastening structure between last connector assembly and the shell, thereby both are in the loose fit state, when the actual use of product, last connector assembly inserts in the process of socket, the opposite force that forms with insertion force concentrates on the support pipe of connector assembly at the application point on the shell, and is delivered to by this supports pipe and wiring board and covers, by covering and the buckle structure of shell overcomes opposite force, easily produce and support pipe and phenomenons such as buckle structure is loosening, fracture, cause product normally not use.
Two, owing to fix by long spiro nail and support pipe between the wiring board and between wiring board and the last connector assembly, after producing loosening and displacement because of above-mentioned reason between each parts, the position that is arranged on the demonstration charactron on the wiring board foremost also can produce displacement in various degree, dislocation between the display window that causes and cover directly influences product appearance.
Summary of the invention
To be solved in the utility model is the above-mentioned defective that prior art exists, and a kind of follow-on time relay is provided.
The technical scheme that solves the problems of the technologies described above employing is: a kind of time relay, comprise shell, lid, go up connector assembly and circuit board module, it is characterized in that described upward connector assembly and circuit board module are fastening with described shell respectively, described lid and described shell are clasped.
The time relay of the present utility model because last connector assembly and shell are directly fastening, can stop connector assembly to get loose, break from shell.And because last connector assembly and wiring board are relatively independent, reaction force suffered in last connector assembly and process that shell cooperates can not be delivered on the wiring board, avoided the demonstration charactron effectively and the form that covers between the generation of inconsistent phenomenon.
As further improvement of the utility model, last connector assembly and shell adopt following mode to realize fastening: the described connector assembly of going up is provided with one group of lug, be provided with one group of corresponding support hook at described outer casing bottom, form notch between described support hook and the outer casing bottom, described lug matches with described notch.
Further improve as of the present utility model, described support hook is an elastomer, offers one group of opening at outer casing bottom and described support hook corresponding section again; Described lug rear end is provided with boss, and described boss is corresponding one by one with described opening.
Described lug is advisable with 2-4, and preferred 3, and on the even or inhomogeneous excircle that is arranged on connector assembly.
Further improve as of the present utility model, described circuit board module is made of four wiring board splicing-in, and the circuit plate that is arranged on front end is fastening by the buckle structure of shell and lid.Described lid bottom bead is provided with the screw for the fastening usefulness of the time relay.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the existing time relay.
Fig. 2 is the structural representation of the utility model time relay.
Fig. 3 is pack into a schematic diagram behind the shell of wiring board.
Embodiment
With reference to Fig. 1, the existing time relay is by the time relay, constitute by shell 1, lid 7, last connector assembly 2 and circuit board module, described circuit board module 3,5 comprises the wiring board 3,5 that pair of parallel is provided with, described connector assembly 2 front ends of going up are provided with three support pipes 13, trip bolt 14 cooperates with clamp nut 4 after passing through the location hole 12 that supports on pipe 13, the wiring board 3 successively, support the location hole 10 on pipe 11, the wiring board 5 from the location hole on the last connector assembly 2.The last connector assembly 2 and the circuit board module that assemble are inserted in the shell 1, and it is fastening with nut that trip bolt is passed through location hole 6 backs that offer on the shell front end bead 28 on location hole 20 and the wiring board 5.The buckle 9 of lid on 7 snapped in the bayonet socket 27 on the shell 1, make cover 7 fixing with shell 1, and make show charactron with cover on 1 form 8 over against.The time relay of said structure, its defective front was described, and did not repeat them here.
With reference to Fig. 2,3, the time relay of the present utility model is made of shell 1, lid 7, last connector assembly 2 and circuit board module 15.Evenly be provided with three lugs 14 on the excircle of described upward connector assembly 2, be provided with one group of corresponding support hook 26 in described shell 1 bottom, form notch 25 between described support hook 26 and the outer casing bottom, described lug 14 matches with described notch 25.
Described support hook 26 is an elastomer, offers one group of opening 24 in shell 1 bottom and described support hook 26 corresponding sections; Described lug 14 rear ends are provided with boss 22, and described boss 22 is corresponding one by one with described opening 24.
To go up connector assembly 2 and insert in the shell 1 and rotation, make in the front end 21 screw-in support hook 26 and the notch 25 between the outer casing bottom of lug 14.When the boss 22 of the rear end of lug 14 screwed in notches 25, support hook 26 was backed down.When the boss 22 of the rear end of lug 14 is threaded to opening 24 places of outer casing bottom, under the elastic force effect of support hook 26 self, boss 22 is snapped in the opening 24.So last connector assembly 2 is just reliable fastening with shell.
During taking-up, will go up connector assembly 2 and be pulled outwardly to boss 22 and opening 24 disengagements, connector assembly 2 just can separate with shell 1 going up connector assembly 2 to lug 14 and notch 25 are broken away from the reverse rotation then.
