Abstract
The utility model discloses a contact module with a mechanism for preventing the falling-off of a bolt. The contact module comprises a module body and a wiring bolt, wherein a stationary contact assembly and a movable contact assembly are disposed on the module body. The contact module is characterized by further comprising two bolt falling-off preventing inserts which are used for being fixedly connected with the wiring bolt, wherein the two bolt falling-off preventing inserts are symmetrically and slantwise disposed at the both sides of the lower part of the module body. The problem that the bolt is easy to fall off in wiring can be effectively solved. The free falling-off of the bolt in wiring can be realized if the inserts are removed during assembly, so that the functions of the contact module are increased.
Description
Technical field
The utility model relates to a kind of contact modules with anti-toner screw mechanism.
Background technology
The shift knob of low-voltage electrical apparatus is of many uses, can satisfy the occasion of user to the multiple demand of selection, conversion and control.Contact modules is the important component part of general shift knob.
The most installation contact terminal screws that require of employed in the market novel contact module.Existing contact modules makes the terminal screw of installation owing to structural reason, comes off easily, causes unreliable on the serviceability.
Summary of the invention
The utility model is in order to overcome the above-mentioned shortcoming that prior art exists, and a kind of contact modules with anti-toner screw mechanism that provides, the coming off of the terminal screw when this contact modules can effectively prevent to install.
The technical scheme that the utility model is taked is: have the contact modules of anti-toner screw mechanism, comprise module body, terminal screw, described module body is provided with fixed contact assembly and moving contact component; Be characterized in that comprise that also two are used for fixing the anti-toner screw mold insert that connects said terminal screw, these two anti-toner screw mold insert symmetries are obliquely installed the both sides, bottom in said module body.
Above-mentioned contact modules with anti-toner screw mechanism, wherein, described anti-toner screw mold insert comprises a terminal screw installation portion, a fixed part that is connected as a single entity, described terminal screw installation portion is provided with installing hole; The both sides, bottom of described module body respectively are provided with the mold insert placement hole of a ccontaining said fixed part; Described fixed part is arranged in the said mold insert placement hole, and described terminal screw installation portion stretches out outside said mold insert placement hole through the through hole that is provided with on the described mold insert placement hole sidewall; Described terminal screw passes through said installing hole, adopts pad, nut to be fixed on the terminal screw installation portion of said mold insert.
Above-mentioned contact modules with anti-toner screw mechanism, wherein, the diameter of the installing hole on the terminal screw installation portion of described anti-toner screw mold insert greater than the terminal screw head diameter less than the maximum circumscribed circle diameter of pad.
Above-mentioned contact modules with anti-toner screw mechanism, wherein, described be connected as a single entity terminal screw installation portion and fixed part side-looking are L-shaped; The port wall of the through hole that is provided with on the sidewall of described mold insert placement hole tilts with respect to the axis; When the fixed part of said anti-toner screw mold insert was arranged in the described mold insert placement hole, described terminal screw installation portion was the aperture that tilts to pass the through hole that is provided with on the sidewall of said mold insert placement hole.
Above-mentioned contact modules with anti-toner screw mechanism, wherein, described terminal screw installation portion angle of inclination is less than 90 degree.
Because the utility model has adopted above technical scheme, an anti-toner screw mold insert is set, the problem that screw comes off easily when effectively having stoped wiring on contact modules.If in assembling, remove this mold insert, screw freely comes off when can realize wiring, and the function of contact modules is increased.
Description of drawings
Fig. 1 is the contour structures sketch map (part that anti-toner screw mold insert is set on the module body is analysed and observe) that the utlity model has a kind of embodiment of the contact modules of preventing toner screw mechanism.
Fig. 2 is the structural representation of a kind of embodiment of anti-toner screw mold insert of the utility model.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in detail, enable to understand better performance, the characteristics of the utility model.
See also Fig. 1, the utlity model has the contact modules of anti-toner screw mechanism, comprise module body 1, cover on the module lid 2 of module body both sides, described module body is provided with fixed contact assembly and moving contact component (not shown).Comprise that also two are used for fixing the anti-toner screw mold insert 4 that connects said terminal screw 3, these two anti-toner screw mold insert symmetries are obliquely installed the both sides, bottom (only shown among the figure and be arranged on a side) in said module body.
Please combine to consult Fig. 2.The utlity model has in the contact modules of anti-toner screw mechanism, described anti-toner screw mold insert 4 comprises a terminal screw installation portion 41, a fixed part 42 that is connected as a single entity, and described terminal screw installation portion is provided with installing hole 411.The both sides, bottom of described module body respectively are provided with the mold insert placement hole 5 of a ccontaining said fixed part.Described fixed part is arranged in the said mold insert placement hole, and described terminal screw installation portion 41 stretches out outside said mold insert placement hole through the through hole 51 that is provided with on the described mold insert placement hole sidewall.Described terminal screw 3 passes through said installing hole, adopts square washer 31, nut to be fixed on the terminal screw installation portion of said mold insert.
In the present embodiment, the described terminal screw installation portion 41 that is connected as a single entity is L-shaped with fixed part 42 side-lookings.The port wall 51 of the through hole that is provided with on the sidewall of described mold insert placement hole tilts with respect to axis 100.When the fixed part of said anti-toner screw mold insert was arranged in the described mold insert placement hole, described terminal screw installation portion was the aperture that tilts to pass the through hole that is provided with on the sidewall of said mold insert placement hole.The angle that described terminal screw installation portion tilts is less than 90 degree.Like this, the terminal screw installation portion of inclination can with terminal screw retaining the terminal screw installation portion with interior module body on.
Again since the diameter of installing hole 411 on the terminal screw installation portion of described anti-toner screw mold insert 4 greater than the terminal screw head diameter less than the maximum circumscribed circle diameter of square washer, thereby realize the problem that effectively stops terminal screw when wiring is installed, to come off easily.
If in assembling, remove this anti-toner screw mold insert, freely the coming off of screw when can also realize wiring increases the function of contact modules.
Above-described, be merely the preferred embodiment of the utility model, be not scope in order to qualification the utility model, the foregoing description of the utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model changes and modification, all fall in the claim protection range of the utility model.
