(a) Technical Field of the Invention
The present invention relates to a fuse seat, and in particular, to a fuse seat for filter which is easily operated, and conveniently installed, low cost in production and has a small volume.
(b) Description of the Prior Art
The insertion seat 1 has a cavity 10 for the holding of the seat body 2, and within the cavity 10, there are two sets of positive and negative conductive plate 11 linked to the electronic components 3 at the other side of the insertion seat 1. The electronic components 3 are externally covered by a metallic housing 30. The two lateral walls of the cavity 10 are provided with a sliding slot 12 for the sliding and engagement of the two lateral sides of the seat body.
The seat body 2 has a chamber 20 for the holding of fuse 31. The two lateral sides of the seat body 2 are each protrudingly provided with a sliding block 21 so that the sliding block 21 is slidably engaged within the sliding slot 12.
The sliding block 21 is slidably engaged within the sliding slot 12 and the seat body 2 at the insert seat 1 is formed as a drawer and the fuse 31 can be inserted to the cavity 10.
The drawbacks of the convention fuse seats are:
Accordingly, it is an object of the present invention to provide a fuse seat for filter, which mitigates the above drawbacks.
Accordingly, it is an object of the present invention to provide a fuse seat for filter having an insertion seat and a cavity at the bottom section of the insertion seat characterized in that a positive and a negative conductive plate are respectively mounted to the two lateral sides of the cavity and the bottom section of the cavity for contacting with the positive and negative terminal of the fuse, and one lateral wall of the cavity is provided with a guiding slot and the two sides of the slot wall of the guiding slot are provided with a positioning recess and one lateral side of the seat body is provided with two engaging slot for engaging one end of the fuse, and between two engaging slot, a support block is mounted, and one lateral side of the support block is provided with sliding plate allowing sliding movement within the guiding slot, and the sliding plate has a positing protruded block for engagement at the positioning slot. The seat body and the insertion seat are separable so that a fuse can be loaded or unloaded and the large volume is greatly reduced.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIGS. 3 to 5, there is shown a fuse seat for filter comprising an insertion seat 4 having a drawer-like base seat 5.
The insertion seat 4 has a cavity 40 for holding the seat body 5. The cavity 40 contains two sets of positive and negative plates 41, and the positive and negative plates 41 are respectively mounted at the two sides and the bottom section for respectively contacting with the positive and negative terminal of the fuse 62. The other end of the positive and negative conductive plate 41 is connected to the electronic components 6 at the other side of the insertion seat 4. The exterior of the electronic component 6 is covered with a metallic housing 60. The conductive plates 41 at the two sides and the wall of the slot of the cavity 40 is provided with a gap, and the other lateral wall of the cavity 40 is a guiding slot 42 allowing the displacement of the seat body 5. The two lateral walls of the guiding slot 42 are respectively mounted with a positioning slot 43. The two lateral sides of the insertion seat 4 are provided with an engaging slot 44. The metallic housing 60 has an engaging plate 61 which bent inward. The engaging plate 61 is engageable within the engaging slot 44, as shown in
One lateral side of the seat body 5 is provided with two engaging slot 50 for the engagement of one end of the fuse 62. A supporting block 51 is provided between two engaging slot 50. The two lateral sides of the supporting block 51 are formed into slots 52 for engagement of the fuse 62 at the side. The end portion of the supporting block 51 is protrudingly mounted with a guiding block 54. Further, the supporting block 51 is provided with two sliding plates 55, and the guiding block 54 and the sliding plate 55 are slidably mounted within the guiding slot 43. The sliding plate 55 is protrudingly mounted with a positioning protruded block 56 which can be engaged with the positioning slot 43. The two lateral sides of the seat body 5 are respectively mounted with an urging block 53 which can urge the rear section of the conductive plate 41 at the two lateral sides so that the conductive plate 41 is forward inclined and has an excellent contact with the fuse 62.
In accordance with the present invention, the advantages are as follows:
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
