Description

Improved fuse base construction

The utility model belongs to the additional device of electrical equipment, and it relates to a kind of improvement of fuse holder structure.

Existing fuse holder, structure is comparatively numerous and diverse, shown in Figure 2 as Fig. 1, its primary structure is made up of pedestal 1 and cap body 2, the bottom surface of pedestal 1 and side are provided with a

square hole

11,12, make the following conducting strip 13 that is placed in the pedestal 1 and last conducting strip 14 thus square hole stretch out, following conducting strip 13 upper ends are a disk 131, be with a spring 15 between the bottom surface of this disk 131 and pedestal 1, end is a ring body 141 on the last conducting strip 14, is enclosed within the inwall of pedestal 1, cap body 2 central authorities are connected with a metallic copper body 21, be inserted in a reed 22 in the metallic copper body 21, the engaging key 22 of metallic copper body 21 front ends is stuck on the ring body 141 of conducting strip 14, in order to attachment cap body 2 and pedestal 1.When fuse 3 places pedestal, cap body 2 covers engaging, fuse is subjected to the roof pressure of cap body, to lower compression spring 15, the reaction force of spring is with the two end cap bodies 31 up and down of

fuse

3,32 peak between reed 22 and the disk 131, relend 21 contacts of conducting metal copper body and go up the ring body 141 of conducting strip 14 upper ends, make two conducting strips 14 up and down, 13 form a current path, therefore, only for forming a current circuit by fuse 3, adopted too much element to assemble, this will cause manpower, material resources and the waste on man-hour, and electric current must instead will influence its electric conductivity as loose contact through multifaceted contact.

The purpose of this utility model is: provide a kind of simple in structure, cost is low, and the multiple fuse holder structure by the dress mode of being convenient to by dress, checking, change.

The utility model is achieved in that its agent structure is made of hollow base and cap body two parts of being with band spring conducting strip, it is characterized in that: hollow base is a portion, is up established externally threaded cap seat portion four parts by the ring portion of the bigger spiral shell portion of diameter, diameter maximum and top successively and be linked to be one and wholely constituted by the lower end, on the anchor ring that is caused because of the diameter difference between base bottom surface and tube portion and spiral shell portion, a slot is arranged all, make the conducting strip that is enclosed within the pedestal and elastic conducting strip partly thus two slots stretch out; Spiral shell portion two side planes are provided with hooking sheet; Ring portion both sides appropriate location is provided with the twice embeded slot; Cap body inwall is provided with screw thread, or root edge has two chimeric keys of extension, and an end that is enclosed within the elastic conducting strip in the pedestal is the shape shape that arches upward, and the positioning key of a projection is established at the position therebetween.

Detailed structure of the present utility model is provided by the embodiment accompanying drawing:

Fig. 1 is the front section view of existing fuse holder.

Fig. 2 is the side sectional view of existing fuse holder

Fig. 3 is a three-dimensional element exploded view of the present utility model

Fig. 4 is the utility model lateral action schematic diagram

Another moves schematic diagram by the dress mode to Fig. 5 for the utility model

Fig. 1 Fig. 2 introduces in above-mentioned prior art.

Fig. 3 is the utility model three-dimensional element exploded view, among the figure hollow base 4 be by lower end tube portion 41, cap seat portion 46 4 parts of the ring portion 45 of up diameter is bigger successively spiral shell portion 43, diameter maximum and top are linked to be an integral body and constitute.Tube portion bottom surface offers a slot 42, also be provided with a slot 44 on the anchor ring that tube portion 41 and spiral shell portion 43 are caused because of the diameter difference, spiral shell portion both sides are provided with the plane, respectively offer square opening 431 on the plane, 432, two square openings are provided with two hooking sheets 433,434, two hooking sheets and pedestal fuse, be slightly perk shape at its tail end, the top of spiral shell portion 43 is the ring portion 45 of diameter maximum, be provided with twice embeded slot 451 at ring portion 45 both sides appropriate locations, the top of ring portion 45 then is the cap seat portion 46 of the top of pedestal 4, be provided with screw thread outside the cap seat portion, be inserted in a conducting strip 5 in pedestal 4, the lower end of conducting strip 5 is passed and is exposed to outside the pedestal 4 by the slot 42 of base bottom surface, these conducting strip 5 upper ends are a circular disk 51, are with spring 6 between this disk 51 and pedestal 4 bottom surfaces.Simultaneously, in pedestal 4, also be with an elastic conducting strip 7, the lower end of this elastic conducting strip 7 passes and is exposed to outside the pedestal 4 through another slot 44 of pedestal 4, elastic conducting strip 7 upper ends are the shape shape that arches upward, and the positioning key of a projection is offered at the position therebetween, making to hold on this elastic conducting strip 7 to stay in the pedestal, and height is neat with pedestal 4 tops altogether, the cap seat portion 46 on pedestal top, can screw tight with cap body 8, or embeded slot 451 tablings of the chimeric key 81 that is extended by cap body 8 root edge both sides and pedestal.

Fig. 4 is the utility model lateral action schematic diagram, when fuse 3 is put into pedestal 4, cap body 32 contacts with the disk 51 of conducting strip 5 under the lower end, when 31 parts of the uppercap body of upper end are exposed to pedestal 4, the chimeric key 81 of cap body 8 embeds in the embeded slot 451 of pedestal 4, bottom until embeded slot 451, just rotate engaging, at this moment, the bottom of cap body 8 promotes fuse 3 downwards, spring 6 in the compression pedestal 4, the reaction force that ends rear spring 6 when cap body 8 cards instead presses closer the disk 51 of conducting strip 5 the following cap body 32 of fuse 3, simultaneously, the uppercap body 31 of fuse 3 also slightly elasticity of compression conducting strip 7 upper ends arch upward partly, make it to press closer fuse 3 uppercap bodies 31, like this, conducting strip 5 can connect into a direct conductive path via fuse 3 with elastic conducting strip 7.

Fig. 5 be the utility model another press the action schematic diagram of dress mode, as shown in Figure 5, it mainly is by the internal thread of cap body 8 cap body 8 to be locked with pedestal 4 to screw tight, make the upper and lower cap body of fuse as Fig. 4, suppress conducting strip and elastic conducting strip, and form a conducting strip and elastic conducting strip direct conductive path by fuse.

The utility model has the advantage of: simple in structure, cost is low, when conducting strip and elastic conducting strip consist of a conductive path by fuse, has avoided multiple-contact, and electric conductivity is better; Check 2, or to change fuse convenient, cap body 8 need only be outwarded winding that fuse is subjected to push away on the elastic force of spring 6, make being exposed to outside the pedestal 4 partly, be beneficial to fuse and take out and check or change; 3, have multiple by the dress mode, pedestal 4 and cap body 8 or chimeric or screw lock, all very convenient. 4, the hooking sheet 433,434 in the pedestal 4 spiral shell sections is reasonable in design, and when pedestal inserted 3 holes of fuse of electrical equipment, the tail end of two hooking sheets 433,434 perks was subjected to an interior pressure, waits rear two hooking sheets of fully insertion then to takeoff, and pedestal 4 is stuck fully.
