Description
Technical Field
The utility model relates to the technical field of high-voltage switch equipment, in particular to a high-toughness plum blossom contact spring for a high-voltage switch.
Background
The electric connection in the high-voltage switch equipment is generally realized by adopting a connection mode of a plum blossom contact, and has strict requirements on the holding force of the plum blossom contact. The existing plum blossom contact generally adopts one or more hooked springs to obtain holding force (as shown in figure 3 in the following description) through end-to-end connection of hooks at two ends of the spring, but the end-to-end connection positions of the springs are connected through the hooks, and the hook connection positions bear most of holding acting force, so that the problem of breaking is easy to occur; meanwhile, when a large current passes through, sparks are easily generated at the position, even a burning and dissolving phenomenon is easily generated, which seriously affects the safety and reliability of the high-voltage switch equipment, therefore, the existing improved technology (as shown in the attached figure 4 of the specification) changes a hook spring into a main spring and a connecting spring, wherein the outer diameter of the main spring is larger than that of the connecting spring, one half of the connecting spring is screwed into the internal thread at one end of the main spring, and the other half of the connecting spring is screwed into the other end of the main spring. The problem is that a longer connecting spring is added in the two ends of the main spring, the strength of the connecting part is increased, the expansion and contraction forces of the adjacent contact pieces and other contact pieces are different, the using effect is still influenced, the structure is complex, and the manufacturing cost is high.
Therefore, be CN201975274U like patent number, be named as a plum blossom contact with having a hook spring, disclose including the main spring, the left end of main spring or right-hand member are equipped with the extension spring joint that is the integrated into one piece structure with the main spring, are equipped with interior spiral line on the inner wall of main spring, are equipped with the outward spiral line of mutually supporting with interior spiral line on the outer wall that the extension spring connects, and a problem that sets up like this lies in that the extension spring connects and main spring integrated into one piece for holistic spring all will twist reverse in step when connecting, and main spring global design is generally inseparable relatively, and is comparatively loaded down with trivial details when leading to the rotation.
In order to solve the problems, the scheme is developed accordingly.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides a high-toughness high-voltage switch plum blossom contact spring, which solves the problems in the background technology.
(II) technical scheme
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a high tenacity high tension switchgear plum blossom contact spring, includes the main spring that is formed along the coiling of many circles of helix by the spring wire, the one end of main spring is equipped with the fixing base one with main spring integrated into one piece, swing joint has the connector on the fixing base one, and the outer end fixedly connected with joint spring of connector is equipped with the external screw thread on the wherein joint spring for the other end threaded connection of joint spring and main spring one.
Preferably, the other end of the spring is integrally formed with a second fixing seat, an internal thread is arranged on the inner wall of the second fixing seat, and the second fixing seat is connected with the spring in a threaded manner.
Preferably, the size of the connector is larger than that of the first fixing seat, and the connector is sleeved on the periphery of the first fixing seat and is rotatably connected with the first fixing seat.
Preferably, the radial size of the connecting head and the radial size of the second fixing seat are consistent with the radial size of the main fixing seat.
(III) advantageous effects
After adopting the technical scheme, compared with the prior art, the utility model has the following advantages: according to the high-toughness plum blossom contact spring for the high-voltage switch, the end parts of the plum blossom contact spring can be tightly connected without rotating the main spring only by rotating the connector, and the plum blossom contact spring is more convenient to operate.

Detailed Description
The utility model is explained in more detail below with reference to the figures and examples.
As shown in fig. 1 and 2: the utility model provides a high tenacity high-tension switch plum blossom contact spring, includes main spring 3, main spring's left end and right-hand member be equipped with main spring 3 fixing base one 7, fixing base two 8 as integrated into one piece structure, are equipped with internal thread 10 on the inner wall of fixing base two 8, swing joint has connector 6 on the fixing base one 7, the outer end fixedly connected with coupling spring 5 of connector, wherein is equipped with external screw thread 9 on the coupling spring 5 for the internal thread 10 threaded connection who sets up on coupling spring 5 and the fixing base two 8.
Because the inner side of the main spring 3 is provided with the internal thread 10, the work is relatively complex and compact, and the scheme is improved, the other side of the main spring is directly connected with the second fixed seat 8 externally, and the internal thread 10 is arranged on the inner side of the main spring, so that the work is relatively simple and convenient.
Referring to fig. 5, specifically, the connecting head 6 is rotatably connected to the first fixing seat 7, that is, the connecting head 6 can rotate relative to the first fixing seat 7 and drive the joint spring 5 to rotate.
This scheme only needs to rotate connector 6, can realize need not to rotate the connection that main spring can accomplish its tip, and it is more convenient to operate.
The further design lies in, is unanimous with the radial dimension of owner with the radial dimension setting of connector 6 and two 8 of fixing base for both hug closely/laminate after connecting, and level with main spring 3, make main spring 3's end connection inseparabler.
