Abstract
The invention relates to a contact finger type isolating switch. The contact finger type isolating switch comprises a contact finger made of a conductive material and a contact seat, wherein a ball socket is arranged on one side, facing the contact finger, of the outer end, contacting with the contact finger, of the contact seat; a ball surface is formed on the corresponding position of the contact finger; the contact finger is connected with the contact seat through hard connection made of the conductive material; and soft connection made of the conductive material is arranged between the contact finger and the hard connection as well as between the contact seat and the hard connection. The contact finger type isolating switch has the advantages that: 1) the hard connection is organically combined with the soft connection according to the advantage, such as high stability, of the hard connection and the advantage, such as reliable contacting property, of the soft connection, so reliable connection between the contact finger and the contact seat is guaranteed, the service life of the connection is prolonged and a good practicable effect is achieved; and 2) the soft connection is further arranged in the hard connection and is not influenced by the external environment, so the service life is further prolonged.
Description
Technical field
The present invention relates to a kind of electrical equipment isolating switch technology.
Background technology
Existing finger-contact type isolating switch is provided with a fork-shaped touch base; Connect four groups of fingertips respectively on two fork bodies of fork-shaped touch base; The binding post of fork-shaped touch base is connected with line bank; Each fingertip is provided with the sphere of outside protrusion towards the one side of touch base, and the corresponding ball-and-socket that is provided with concave shaped on the touch base, the fingertip electric current is through sphere, ball-and-socket conduction.Because the accuracy of production process technology is difficult to reach requirement, the loose contact between sphere and ball-and-socket of this traditional product causes temperature rise too high, and isolating switch fingertip burnout phenomenon happens occasionally.
The patent of patent No. position 2005200706124 provides a kind of finger-contact type isolating switch for this reason; The structure of this switch is that fingertip is connected through soft electric conducting material with touch base; Guarantee good contact between the two, improved the security reliability of isolating switch.But also there is certain defective in above-mentioned version; Its material settling out performance of the more rigid electric conducting material of soft electric conducting material is relatively poor; After using longer a period of time; Material property is damaged easily, and perhaps material aging can make closeness of contact between the two reduce, so there is low shortcoming in useful life in this structure.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of fingertip that can keep to be connected reliably with the touch base time, can have the finger-contact type isolating switch in higher useful life again.
Technical scheme of the present invention is: the present invention includes fingertip and the touch base processed by electric conducting material; Ball-and-socket is established towards the one side of fingertip in the outer end that touch base contacts with fingertip; Sphere is established in the relevant position of fingertip; The hard connection that fingertip is processed through electric conducting material is connected with touch base, fingertip and between hard the connection, touch base and establishing by what electric conducting material was processed between hard the connection is flexible coupling.
Further, the said hard connection sealing that will be flexible coupling making the extraneous contact of the discord that is flexible coupling.
Further, establish groove on the touch base, groove is built-in with the cushion block that the upper surface is convex, and cushion block is processed by heat-resistant insulation material.
Further, offer T shape through hole on the touch base, above-mentioned described cushion block is established in T shape through hole inside, bolts in the through hole of cushion block lower end, and bolt is connected on the touch base.
Advantage of the present invention: 1) the present invention utilizes the good advantage of hard connective stability ability; And the reliable advantage of the contact performance that is flexible coupling, both are organically combined, guaranteed that promptly the connection between fingertip and the touch base is reliable; Improve the useful life that connects again, had good practical function; 2) further the present invention will be flexible coupling and be arranged in the hard connection, make its influence that does not receive external environment, further improve its useful life.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that fingertip, 2 is that cushion block, 3 is that touch base, 4 is that bolt, 5 is that connection, 6 firmly is for being flexible coupling among the figure.
Embodiment
The present invention includes the fingertip 1 and touch base 3 processed by electric conducting material; Ball-and-socket is established towards the one side of fingertip in the outer end that touch base 3 contacts with fingertip 1; Sphere is established in the relevant position of fingertip 1, and the hard connection 5 that fingertip 1 is processed through electric conducting material is connected with touch base 3, fingertip 1 and connect between 5 firmly, touch base 3 and connect firmly to establish between 5 and be flexible coupling 6 by what electric conducting material was processed; Preferred the present invention is hard to connect 56 sealings that will be flexible coupling, and makes the extraneous contact of 6 discord that is flexible coupling.
The present invention offers T shape through hole on touch base 3, T shape through hole is built-in with the cushion block 2 that the upper surface is convex, and cushion block 2 is processed by heat-resistant insulation material; Bolts 4 in the through hole of cushion block 2 lower ends, bolt 4 is connected on the touch base 3.
Claims (4)
