Embodiment
Below in conjunction with accompanying drawing, the utility model execution mode is described further:
As Figure 1-4, the utility model is a kind of Novel overload protection switch, includes housing 1, is provided with the left and right pin 2,3 connecting both positive and negative polarity respectively in housing 1; Left pin 2 is fixed with two golden shell fragment 4, and this pair of golden shell fragment 4 other end can be separated by the lifting of temperature during two golden shell fragment 3 and right pin 3 with electric current and to hold with contacting to be formed to tilt; It is narrower than the one end being fixed on left pin 2 and be provided with arc-shaped transition 41 and the corner of two golden shell fragment 4 is circular arc chamfering at joint that described two golden shell fragment 4 tilts end; By arranging left and right pin 2,3 and utilize two golden shell fragment 4 to be electrically connected left and right pin 2,3 in housing 1, so in use, electric current when two golden shell fragment 4 as overload, the temperature of two golden shell fragment 4 will rise, now, the tilting end of two golden shell fragment 4 will upwarp deformation and right pin 3 is separated, turn-off current loop, thus protection power consumption equipment; And after two golden shell fragment 4 tilts a period of time, temperature can decline thereupon, now, two golden shell fragment 4 can automatically reset the formation current circuit that to be connected with right pin 3, ensures continuous usability and the convenience of overload cut-out.And two golden shell fragment 4 is less and joint is provided with arc-shaped transition 41 than the other end near one end of right pin 3, arrange arc-shaped transition 41, like this when transshipping disjunction, arc transition 41 can play certain effect that draws high makes disjunction tilt get Geng Gao, and disjunction is rapider; And the corner of two golden shell fragment 4 being all set to R angle, such product appearance is more attractive in appearance.
In the present embodiment, in described housing 1, the below of two golden shell fragment 4 is provided with the dividing plate 5 that separable two golden shell fragment 4 is connected with right pin 3, the both ends of the surface of this dividing plate 5 are provided with the conductive plate 6 that independently can be electrically connected with two golden shell fragment 4 and right pin 3 respectively, and described dividing plate 5 one end is fixed on the end of reset knob 7; Reset button 7 is arranged in the chute 111 be arranged in housing 1, and the bottom of reset button 7 is provided with back-moving spring 71; In described reset button 7, be provided with round core bore 72, in this circle core bore 72, be provided with indicator light 73, two pins of this indicator light 73 are electrically connected with the conductive plate 6 of dividing plate 5 both ends of the surface respectively; Being fixed on two golden shell fragment 4 one end on left pin 2 also utilizes the other end of two golden shell fragment 4 to be communicated with right pin 3, like this when current overload, two golden shell fragment 4 can tilt with the rising of temperature, now, dividing plate 5 is between right pin 3 and two golden shell fragment 4 to top offset under the effect of back-moving spring 71, open circuit plays overload protective function, the conductive plate 6 be arranged on like this in dividing plate 5 both ends of the surface just can be communicated with two golden shell fragment 4 respectively and right pin 3 makes indicator light 73 light, and prompting subscriber line circuit overload disconnects; And after solving overload problem, just available hand drives dividing plate 5 downward by reset button 7, two so golden shell fragment 4 just can be connected with right pin 3 and form loop; Adopt such structure, not only can realize overload protection function, the safety of protection power consumption equipment, avoids power consumption equipment to damage; Meanwhile, also available hand directly presses reset button 7 and makes overload cut-out Rapid reset, user friendly continuous use, improves the fail safe and convenience that use; Secondly, also carry out reminding user by indicator light 73 when transshipping and disconnecting protection, be convenient to the operating state that user knows switch.
In the present embodiment, for the ease of the installation of left and right pin 2,3 and reset button 7 and two golden shell fragment 4, described housing 1 includes lower house 11 and upper cover body 12, edge, the surrounding of lower house 11 is provided with at least three location counterbores 112, be provided with positioning convex column 121 in the corresponding edge of described upper cover body 12, this positioning convex column 121 can be inserted in the counterbore 121 of location and upper cover body 12 and lower house 11 are located by connecting; Housing 1 is set to Split type structure, although be convenient to production and assembly, because the counterface of lower house 11 and upper cover body 12 is level and smooth, not easily locate when assembling like this, therefore, the end face of lower house 11 adding location counterbore 112, the end face of upper cover body 12 adds positioning convex column 121, utilizing when assembling positioning convex column 121 to insert in the counterbore 112 of location like this, not only can quick position, be convenient to assembling, and positioning precision is higher, is more conducive to operation.
Above-described embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection range of the present utility model.
