Abstract
The utility model belongs to the surge protector field is the effectual special graphite electrode of surge protector of contact who provides to adopting the point contact easily to cause contact failure between current surge protector graphite electrode and the high -pressure discharge needle. Including a plurality of graphite electrode, be equipped with the packing ring that insulating material was made between each graphite electrode, be equipped with the high -pressure discharge needle of hugging closely graphite electrode on each graphite electrode, this high -pressure discharge needle include the annular contact segment that is connected with graphite electrode and with the conduction part of a cyclic annular contact segment body coupling. A terminal surface of the last high -pressure discharge of the hugging closely needle of graphite electrode is equipped with the sunk part that supplies the embedding of high -pressure discharge needle, and the high -pressure discharge needle is embedded on this sunk part. The annular contact segment of high -pressure discharge needle department is equipped with logical groove, the utility model discloses that adopt between well high -pressure discharge needle and the graphite is surface to surface contact to avoided the condition that produces contact failure between the two, the relapse that can stand the surge acts on many times, and the practicality is strong.
Description
Technical field
The utility model belongs to Surge Protector field, particularly relates to Surge Protector special graphite electrode.
Background technology
As shown in Figure 1; the graphite electrode of existing Surge Protector and and electrion pin between what adopt is point cantact; under the repeated multiple times effect of surge; weak spot material is bad; the electromotive force vibrations that its impulse current produces force contact point to form open circuit, cannot the electric discharge of trigger multi-layer Connexin.Lose the meaning of protective circuit.
Utility model content
The utility model object be for existing Surge Protector graphite electrode with adopt point cantact easily to cause loose contact between electrion pin and provide a kind ofly contact effective Surge Protector special graphite electrode.
The utility model is achieved by the following technical solution:
Surge Protector special graphite electrode; comprise multiple graphite electrode; the packing ring that isolation material is made is provided with between each graphite electrode; each graphite electrode is provided with the electrion pin being close to graphite electrode, the contact portion that this electrion pin comprises the ring-type be connected with graphite electrode and the conduction portion be connected with ring-like contact part one.
The end face described graphite electrode being close to electrion pin is provided with the sunk part embedded for electrion pin, and electrion pin is embedded on this sunk part.
The contact site office of described electrion needle ring shape is provided with groove, makes the contact portion of ring-type have elasticity.
Described electrion pin is made for having flexible metal material.
The beneficial effects of the utility model: what adopt between the utility model mesohigh spray point and graphite is plane-plane contact, thus avoids the situation producing loose contact between the two, can stand the repeated multiple times effect of surge, practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of electrion pin of the present utility model;
Fig. 4 is the sectional view of graphite electrode of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As in Figure 2-4; Surge Protector special graphite electrode; comprise multiple graphite electrode 1; the packing ring 2 that isolation material is made is provided with between each graphite electrode; it should be noted that the electrion pin 3 being provided with on each graphite electrode and being close to graphite electrode 1, the contact portion 31 that this electrion pin comprises the ring-type be connected with graphite electrode and the conduction portion 32 be connected with ring-like contact part one.The end face described graphite electrode being close to electrion pin is provided with the sunk part 11 embedded for electrion pin, and electrion pin 3 is embedded on this sunk part.The contact site office of described electrion needle ring shape is provided with groove 33, the contact portion of ring-type is made to have elasticity, the inner ring of contact portion is all contacted with graphite electrode with side, thus make electrion pin be connected between graphite electrode tightr, contact area is larger, and contact effect is better, and described electrion pin is made for having flexible metal material, it is too high that the setting of groove also makes the machining accuracy of electrion pin not need, and processes easier, quick.
(to flexible metal material this electrion pin adopt the metal material of conduction to make, one end face of electrion pin is provided with the sunk part embedded for electrion pin, electrion pin is embedded on this sunk part, with graphite electrode compact siro spinning technology after product is screwed).
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection range of the present utility model.
