Embodiment
Below in conjunction with accompanying drawing, the utility model execution mode is described further:
As Figure 1-5, the utility model is a kind of overcurrent 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; Be electrically connected by two golden shell fragment 4 between described left and right pin 2,3, the dividing plate 5 that separable two golden shell fragment 4 is connected with right pin 3 is provided with below two golden shell fragment 4, 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, be provided with indicator light 73 in this circle core bore 72, two pins of this indicator light 73 are electrically connected with the conductive plate 5 of dividing plate 5 both ends of the surface respectively; Left and right pin 2,3 is set in housing 1 and utilizes two golden shell fragment 4 to be communicated with, 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, and 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 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 when transshipping and disconnecting protection, be convenient to the operating state that user knows switch.
In the present embodiment, in order to farthest save the material of two golden shell fragment 4, described left pin 2 includes pin body 21 and caulking part 22, described caulking part 22 is structure as a whole with pin body 21 for step-like, and two golden shell fragment 4 is fixed on caulking part 22 and caulking part 22 is given prominence to towards the right side of pin body 21; Because the material of two golden shell fragment 4 is more expensive; in order to protect specified overload power; width just cannot reduce; till; the applicant adopts the left pin 2 of this tilting to coordinate two golden shell fragment 4; position by two golden shell fragment 4 fixing on left pin 4 tilts to give prominence on the right side of pin body 21; just farthest can shorten the length of two golden shell fragment 4 during the two golden shell fragment 4 of such installation but also its overload interrupting performance can be protected; thus the material reducing two golden shell fragment 4 drops into, and reduces production cost.
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 112 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.
In the present embodiment, described 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, and the corner of two golden shell fragment 4 is arc transition angle; R angle is all set at four angles of two golden shell fragment 4, product is more attractive in appearance, and establishes arc transition 41 at the separating end of tilting of two golden shell fragment 4 and the joint of stiff end, so just transship disjunction time, arc transition 41 can play certain effect that draws high makes disjunction tilt get Geng Gao, and disjunction is rapider.
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.
