The housing 100 is open to both sides for fixing and protecting the terminal portion made up of the connection terminal 110, the rotation boss 120, the connection terminal 130, the elastic body 140 and the fixing body 150, An elastic clip 101 which is elastically deformed when receiving an external force is vertically and symmetrically formed in the central portion of the inner side wall 102. The engagement protrusion 102 and the fixing groove 103 are vertically and symmetrically arranged at regular intervals Respectively.

Here, the housing 100 may be integrally formed with a plurality of terminal portions such that a plurality of terminal portions are arranged side by side, or may be formed of an insulating material such as a synthetic resin.

For example, as shown in FIG. 3 and FIG. 4, four housings 100 are integrally formed in parallel in the horizontal direction for the purpose of electrically connecting the main busbars of the respective R, S, T, and N phases .

The connection terminal 110 is formed in a plate shape so that both ends of the connection terminal 110 are tightly coupled to the engagement protrusion 102 of the housing, and a wire connection hole 111 for easy and easy connection to a terminal such as a wire or a cable is formed at one end Respectively.

Here, it is preferable that the connection terminal 110 is formed of a metallic material or alloy such as copper or aluminum having excellent mechanical strength, heat resistance and electrical conductivity.

Here, the rotary boss 120 is preferably formed of a metallic material or alloy such as copper or aluminum, which is excellent in mechanical strength, heat resistance and electrical conductivity, like the connection terminal 110.

The connection terminals 130 are formed as a pair and are symmetrically arranged on both sides of the rotation boss 120. One end of each of the connection terminals 130 is rotatably coupled to the rotation boss 120 within a predetermined angle range, And each upper surface of one end thereof is electrically connected to the lower surface of the connection terminal 110. [

In addition, an insertion groove 131 for stable connection with the elastic body 140 is formed on the outer surface of each of the connection terminals 130.

Here, the surfaces of the connection terminals 130 facing the outer surface of the rotary boss 120 are preferably formed in the shape of irregularities 132 in order to minimize the friction area with the rotary boss 120 during the rotation operation .

That is, since the area of friction with the rotation boss 120 is minimized by the irregularities 132 of the connection terminals 130, the rotation around the rotation boss 120 is smoothly and easily performed.

The elastic body 140 has a rounded one-sided shape to give elastic force to return to the original position when the connection terminals 130 are rotated in opposite directions about the rotation boss 120, Quot; U "shape, and both ends having a spring action are coupled to the side surfaces of the connection terminals 130. Insertion protrusions 141 are formed on opposite sides of the opposite sides of the insertion protrusions 141, Respectively.

The fixing body 150 is coupled to the lower surface of the rotation boss 120 so that the connection state of the rotation boss 120, the connection terminals 130 and the elastic body 140 is maintained, and both ends are fixed to the fixing groove 103 of the housing. And an engagement hole 151 through which the elastic clip 101 of the housing is inserted is formed on the upper surface.

A spacing pin 152 is bended at one end of the fixing member 150 to prevent contact between the connection terminals 130 from coming into contact with each other because the gap between the connection terminals 130 is narrower than a predetermined range.

The connecting terminal 110, the rotary boss 120, and the fixing body 150 are overlapped so as to overlap with each other, and the rivet 160 is inserted into the hole formed in each of the connecting terminal 110, A stable connection state can be maintained.

The connector for power distributor according to the embodiment of the present invention is configured such that both ends of the fixing body 150 are inserted into the fixing groove 103 of the housing in an interference fit manner and the elastic clip 101 of the housing When it is elastically deformed by surface contact with the fixture 150 and is positioned in the fixation hole 151 of the fixture, it quickly returns to its original position due to its own elasticity and becomes a mutual engagement state.

Therefore, when increasing or decreasing the load capacity due to the fluctuation of the power consumption, the plurality of connection terminals 110 and the connection terminals 130 can be easily stacked and assembled at a predetermined interval up and down.

Since the elastic clip 101 and the engaging protrusions 102 and the fixing grooves 103 are formed in the interior of the housing 100 at regular intervals vertically and symmetrically, Even if the connection terminals 130 and the connection terminals 130 are inserted into the housing 100 symmetrically with each other, unlike the related art, the connection terminals 130 are not overlapped with each other, so that the safety such as electrical shorts due to slip can be prevented.

In addition, when the connection terminals 130 are connected to the terminal of the terminal block or the bus bar, the connection can be smoothly and stably carried out because the connection terminals 130 are rotated in opposite directions about the rotation boss 120, 140, a spring action to return to the original position occurs, and the terminal or the bus bar of the terminal block can be maintained in a solid connection state.

In addition, since the gap holding pins 152 of the fixed body prevent the gap between the connection terminals 130 from becoming narrower than a certain range, unsafe connection or poor connection can be prevented even if the connection and disconnection operations are frequent .
