Abstract

The utility model provides a conical plug type electric connector. The core texture of the utility model is a cone contact pair and an elastic element which is used for compensation in axial position and is used to tightly bond to the contact pair. The utility model is characterized in that the contact face of a plug and the contact face of a jack (seat) are cone shaped; the elastic element with reliable connection is arranged in the axial direction of the plug or the socket. The utility model has the advantages of realization connection of a plurality of cores with different shafts, simple structure, reliable contact, smaller contact resistance, low temperature rise and long service life. The conical plug type electric connector is particularly suitable for the transmission of various high current.

Description

Conical plug type electric connector

What the utility model provided is that a kind of contact is to being taper, electric connector--the cone plug type electric connector that adhesion guarantees by flexible member (as spring).

The plug of prior art, jack are generally cylindrical, and it is unreliable to contact.Though the contact-making surface that has does not have the axial force distribution element for conical, also be difficult to guarantee the reliability of contact, particularly in same set of plug, socket, have a plurality of contacts to the time, guarantee just difficulty more of the right reliable contact of a plurality of contacts simultaneously.

The purpose of this utility model is the problem for fear of above-mentioned existence, proposes a kind of electric connector of reliable connection--the cone plug type electric connector.

Technical solution of the present utility model: structure as shown in drawings.It is made up of plug, jack (seat), and the contact-making surface of plug, jack (seat) is conical, guarantees reliable flexible member--the spring that contacts of connector axially being equipped with of plug or socket.

Accompanying drawing 1 is the structural representation of the utility model when not connecting, and accompanying drawing 2 is the utility model structural representations when connecting.Among the figure 1 is plug, the 2nd, jack (seat), the 3rd, spring.

Further describe the technical solution of the present utility model and the course of work below in conjunction with accompanying drawing:

Each contact is to comprising plug 1, the spring 3 of jack (seat) 2 and may command adhesion.The contact of one pair of electric connector is to available single, also available a plurality of and parallel distribution setting (disalignment).Under the effect of retaining mechanism 4, can make plug and socket closure or openness.

Plug shown in the accompanying drawing 1 and jack (seat) are on the fixed head that is installed in respectively separately, and spring housing is in socket bar portion, and both ends of the spring withstands on respectively between socket flange and the fixed head.

The initial condition of the course of work, as shown in Figure 1, plug is outside jack (seat), and jack (seat) is withstood on the preceding position of pegging graft by spring, when plug inserts taper hole and continues to advance, socket retreats vertically and compresses spring, puts in place until plugging together, as shown in Figure 2, plug body is by locking device 4(snap close for example) locking, rely on the spring counter-force of design to make conical contact to keeping relative jam-pack state, thereby obtain enough tight and reliable combination, consequently:

Contact is big and bigger contact pressure is arranged to conductive contact surfaces, and contact resistance is minimum, the little order of magnitude of comparable milliohm (m Ω), and temperature rise is low, connect-disconnect life is long, and this is that conventional electric connector is difficult to realize, is particularly useful for the electric power transfer of big electric current.

Characteristics of the present utility model: under elastic acting force, each contact is difficult for forfeiture to the reliability that connects, and compares to conventional electric connector, has prolonged widely working life.

Claims

1, cone plug type electric connector, the contact-making surface that comprises plug, socket, plug, socket (hole) is characterized in that for conical axially being equipped with of plug or socket guarantees the reliable flexible member that contacts of connector.
