Abstract
The utility model relates to the technical field for measuring contacts of a subsurface instrument for a truck and provides a compression spring type weight bar contact which comprises an insulating outer cylinder, a conductive rod and a compression spring; an internal lug boss is fixed at the inner side of the left end of the insulating outer cylinder; the conductive rod capable of penetrating through the internal lug boss is arranged in the insulating outer cylinder; an external lug boss of the conductive rod is fixed at the right end of the conductive rod; the inner diameter of the internal lug boss is greater than the outer diameter of the conductive rod but less than the outer diameter of the external lug boss of the conductive rod; and the compression spring is arranged on the conductive rod between the external lug boss and the internal lug boss of the conductive rod. The compression spring type weight bar contact has reasonable and compact structure and is convenient to use. As a plug is matched with the compression spring, the plug cannot be damaged easily; therefore, the service life is prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to weighted lever contacts Technology field, is a kind of compressed spring type weighted lever contact.
Background technology
The weighted lever contact that is used for the oil field at present is generally banana plug (being commonly called as) formula contact, this contact main application be weighted lever with instrument between connect and weighted lever and weighted lever between connect electric action, use through once or several times going into well, banana plug causes damage easily, instrument string into well is in opens circuit or short-circuit condition; For instrument is run well once more, banana plug must be changed simultaneously, bring very big inconvenience to site operation, production cost increases.
Summary of the invention
The utility model provides a kind of compressed spring type weighted lever contact, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that banana plug is damaged easily and need often to change.
The technical solution of the utility model realizes by following measure: a kind of compressed spring type weighted lever contact comprises the insulation urceolus, contact rod and compression spring; Left end inboard at the insulation urceolus is fixed with inner convex platform, there is the contact rod that can pass inner convex platform inside at the insulation urceolus, right-hand member at contact rod is fixed with the contact rod outer lug boss, the internal diameter of inner convex platform is equipped with the compression spring greater than the external diameter of the contact rod external diameter less than the contact rod outer lug boss on the contact rod between contact rod outer lug boss and the inner convex platform.
Be further optimization and/or improvements below to above-mentioned utility model technical scheme:
Above-mentioned contact rod can comprise plug and barred body; Left end at barred body is fixed with plug, is fixed with the contact rod outer lug boss at the right-hand member of barred body, and the external diameter of plug is less than the external diameter of barred body.
The left side of above-mentioned inner convex platform can be fixedly connected with urceolus tube neck, and the external diameter of urceolus tube neck is less than the external diameter of insulation urceolus, and the internal diameter of urceolus tube neck is big or equal the internal diameter of inner convex platform.
The utility model reasonable and compact in structure, easy to use, owing to adopt the cooperation of plug and compression spring, make plug not fragile, therefore improved useful life, reduced production cost.
