Description
Technical field
The present invention relates to a kind of terminal stud being applicable to ammeter, particularly relate to a kind of terminal stud being provided with hot titanium alloy spring.
Background technology
Terminal stud is a kind of conventional ammeter accessory, for connecting ammeter and outside circuit to be monitored, in prior art, how preventing the terminal stud on ammeter from loosening and even coming off in connection hole is a difficult problem, it is that the Chinese utility model patent of 201210482901.X discloses a kind of terminal stud in the patent No., it comprises junction block and line pressing bolt, the side of described junction block has connection hole, the top of junction block has threaded hole, described threaded hole communicates with connection hole, described line pressing bolt is connected with junction block by threaded hole, it also comprises one with the cap sleeve of internal thread, the upper end of described terminal stud has outside screw, described cap sleeve is threaded with terminal stud, the top of described cap sleeve is provided with lid, described lid has a hole passed for screwdriver, the diameter in described hole is less than the diameter of the nut of line pressing bolt. adopting the terminal stud line pressing bolt of this kind of structure only to move reciprocatingly in cap sleeve, can not come off from junction block, line pressing bolt is not easily lost, and line pressing bolt also would not be occurred to lose the short circuit phenomenon occurred in the product.
But, the installation of line pressing bolt is very inconvenient, and phenomenon of easily getting rusty.
Summary of the invention
For the deficiency that prior art exists, it is an object of the invention to provide a kind of can at the terminal stud being provided with hot titanium alloy spring ensureing to save under not dropping situations line pressing bolt.
For achieving the above object, the present invention provides following technical scheme:
A kind of terminal stud being provided with hot titanium alloy spring, include pedestal, described base interior hollow is formed with installation cavity, described pedestal is fixed with copper cylinder, described cylinder includes and is symmetrical arranged ground the first cylinder and the 2nd cylinder, described first cylinder and described 2nd cylinder are separated from each other, and between described first cylinder and the 2nd cylinder, it is formed with gap, described installation cavity is provided with conductive pole, fixed orifices has been offered in described pedestal side, described fixed orifices is provided with retaining screw, by described retaining screw by spacing for conductive pole in described installation cavity, string holes has also been offered in described pedestal side, described string holes is embedded with coil, described coil is connected with described conductive pole,
End winding support at described conductive pole has hot titanium alloy spring, and described hot titanium alloy spring is clamped in the gap of described first cylinder and the formation of the 2nd cylinder.
Preferred as the present invention, described conductive pole one end is fixed with pushing block, and described hot titanium alloy spring is fixed on described pushing block, and described hot titanium alloy spring is clamped between described first cylinder and the 2nd cylinder.
Compared with prior art, it is an advantage of the current invention that: utilize hot titanium alloy spring to have and expand with heat and contract with cold and possess elastic feature, stretched in the gap of the first cylinder and the formation of the 2nd cylinder, thus can save line pressing bolt, and can ensure that terminal stud can not come off out in the energized state from connection hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of the terminal stud being provided with hot titanium alloy spring in the present invention.
Embodiment
With reference to Fig. 1, the embodiment of the terminal stud being provided with hot titanium alloy spring in the present invention is described further.
As shown in Figure 1, the present embodiment is a kind of hot titanium alloy spring terminal stud, include pedestal 1, described base interior hollow is formed installs cavity 11, described pedestal is fixed with cylinder, described cylinder includes and is symmetrical arranged ground the first cylinder 2 and the 2nd cylinder 3, described first cylinder 2 is separated from each other with described 2nd cylinder 3, and between described first cylinder and the 2nd cylinder, it is formed with gap 4, described installation cavity is provided with conductive pole 5, fixed orifices 6 has been offered in described pedestal side, described fixed orifices is provided with retaining screw 7, by described retaining screw by spacing for conductive pole in described installation cavity, string holes 8 has also been offered in described pedestal side, described string holes is embedded with coil 9, described coil is connected with described conductive pole,
End winding support at described conductive pole have can the hot titanium alloy spring 12 of expanded by heating after powered up, in the gap that described hot titanium alloy spring is clamped in described first cylinder and the 2nd cylinder is formed.
Described conductive pole one end is fixed with pushing block 10, and described hot titanium alloy spring is fixed on described pushing block, and described hot titanium alloy spring is clamped between described first cylinder and the 2nd cylinder by expansion principle.
The above makes the preferred embodiment of the present invention, under not departing from the prerequisite of the principle of the invention for the person of ordinary skill of the art, it is also possible to make some modification and improvement, and these also should be considered as protection scope of the present invention.
