Description

Elastic surface contact wire path connector

The utility model relates to line connector.

Now, line connector and various attaching plug and socket, its structural style is various, but all is that electrode plug is made garden column type or flat type, the elastic force that the own geometric modeling of the electrode of socket and material forms, the cramping plug is finished connection.Its shortcoming is a contact, and not only contact resistance is big, can not satisfy the circuit instructions for use, and phenomenon easily is short-circuited.Sometimes to peg graft repeatedly several times, just can finish circuit and connect.Under the vibration operating mode, connect when breaking during circuit, interpolar causes that electric arc produces melting welding, as ribbon conveyer, the thing that the running of generation phase shortage burns out motor also happens occasionally.Also usually because of loose contact, big, the heating consume electric energy of contact resistance, execute the uneven and grafting deviation of directivity of external force in the use, destroyed the geometric modeling of electrode, make line connector attaching plug and socket life-span very short with the pluggable mode people.Various countries' standard on power insert differs in the world, has limited the versatility of appliances power source plug-in unit.

Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of elastic surface contact, the stable and reliable operation line connector.

Task of the present utility model realizes in following mode: the socket of line connector has a housing, two block-shaped identical semicircle contour bodies are housed in the circular hole on it, the inner arc in its cross section is for lacking circle, outer arc is a full circle, interior circular arc and external arc be not on the same center of circle, and two contour bodies surround the drum electrode plate.Outer round surface at battery lead plate is set with spring, and the radius of spring is slightly less than the outer arc radius of drum electrode.The plug that the column type that radius equals the radius of battery lead plate inner arc is suspended in the installing hole matches with battery lead plate.Its connection electrode jack cross section can be to be similar to two circular scarce circular arcs to surround, and its plug is a cylinder.Also can be to be surrounded by two triangles, the cross section of its jack be a deltiod and square.

The utility model is owing to adopt the column type plug to be connected with socket, reliable operation not only, and anti-vibration, and be convenient to the standardization that power supply and other circuits connect plug-in unit, also have grafting simultaneously conveniently, the advantage of long service life.

Fig. 1 is the utility model front section view;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is another embodiment front section view of the present utility model;

Most preferred embodiment one of the present utility model is as shown in Figure 1: line connector has an insulation shell 1 two block-shaped identical arc surface bodies 3 to be housed in it, form the drum electrode plate, at battery lead plate outer round surface suit cylindrical spring 4, shelves cover 2 is equipped with at two.The radius of column type plug equals the radius of battery lead plate inner arc, because the circle that inner arc forms is for lacking circle, so after the bar head inserts electrode, form outside tension force, tighten at spring under the effect of power, tighten, realized that circuit connects lead-in wire and draws through 5 by two cube electrode barre heads.

Preferred example two of the present utility model is as shown in Figure 3: connecting terminal block has a thick wall shell 2, insulation core body 3 is housed in it, the several terminals seat is housed in the core body, terminal base is matched by two radius garden contour bodies 5 identical with arc length, and to form cross section be that radius equates, the scarce garden jack that arc length equates, the garden post spring 4 that diameter of bore equates with the jack outer diameter is sleeved on the outer wall of two contour bodies, at the two ends of terminal base binding post 1, two connecting line is housed respectively and is connected on the terminal.During use, the insulating sleeve of determining line footpath lead is peeled off, sent in the stringing clip, with hand vice clip is stepped up back wiring 6 and promptly be fixed on the plug-type electric wire connecting junction.

The foregoing description is that single channel connects and three-phase power socket.After the expansion, can realize two-way, the three tunnel, four-way power supply plug and socket or multi-path line connector.During use, determine the centre-to-centre spacing of good each road connectors, rated current voltage just can further be determined the physical dimension of plug and socket, i.e. the classification and the universal standard of definite product.

Claims (1)

1. elastic surface contact wire path connector, constitute by socket and plug, it is characterized in that: a housing is arranged on the socket, two identical semicircle contour bodies of form are housed in the hole, garden on it, the inner arc of its cross section is for lacking the garden, outer arc is whole garden, interior circular arc and external arc be not on the same center of circle, two contour bodies surround the drum electrode plate, surface, outer garden at battery lead plate is set with spring, the radius of spring is slightly less than the outer arc radius of drum electrode, the column type that radius equals the radius of battery lead plate inner arc is suspended in the installing port to pull with electrode and matches, its connection electrode socket cross section can be to be similar to two circular scarce circular arcs to surround, and its plug is a cylinder.
