Embodiment
Describe technical scheme of the present invention in detail by the following examples, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not be interpreted as being the restriction to technical solution of the present invention.
As shown in Figures 3 to 10, a kind of fixing demountable structure of automobile electrical equipment box big current terminal, includes electrical appliance kit body 1, and hold-down nut, conflux sheet 4 and big current terminal 3.
Described electrical appliance kit body 1 is provided with two hold-down nut places 7, and the top at each hold-down nut place 7 is provided with the sheet 4 that confluxes, and described big current terminal 3 is fixed on electrical appliance kit body 1 by bolt 2 after coordinating with the sheet 4 that confluxes.In the present embodiment, hold-down nut place 7 to cave inward part 73 from the side of electrical appliance kit body 1, matches, with the side preventing big current terminal from protruding from electrical appliance kit body for same big current terminal.
The width of described groove 72 matches with the inscribed circle diameter of nut base 6.The height of described groove 72 is greater than the height of nut.The front end of described borderline structure is provided with arc lead angle.
Described nut is the nut structure of band base; The base of described nut is polygonized structure, and in the present embodiment, the base of nut is square structure or rectangle structure, but is preferably even number of sides structure.The outer surface of described nut is cylindrical, and its external diameter is slightly less than the width of convex space 71 upper part.
Described hold-down nut place 7 is groove 72 structure that the outer surface direction of electrical appliance kit body 1 is provided with opening, and the dual-side of groove is respectively provided with the disjunct borderline structure extended in groove with groove bottom, makes groove and edge surround convex space 71; The height of described convex space 71 lower middle portion matches with the height of nut base; The width of groove 72 matches with nut base, to ensure that nut base can push in the convex space 71 of groove formation;
The described sheet 4 totally two that confluxes, matches with a big current terminal respectively, includes and the bolt penetration hole 41 of nut screw connection and anti-big current terminal rotational structure (42 or 43); Described two sheets that conflux are placed, for preventing setup error for symmetrical; Described two sheets that conflux divide into the left and right sides.
Described big current terminal 3 has bolt penetration hole 31 for L-type vibrational power flow, and the anti-rotational structure (32 or 33) that its minor face protrudes downwards coordinates for the anti-big current terminal rotational structure with the sheet that confluxes.The L-type structure of described big current terminal is vertical with the main part of big current terminal to be arranged.
Big current terminal structure coordinates with anti-rotational structure, effectively prevents in the urgent process of bolt 2, the transfer of big current terminal.
Employing " L " the row structural design of big current terminal, the strength enhancing of big current terminal, the distortion reducing the urgent process of big current terminal is impaired.
Nut push-in type designs, and band base nut pushes along electrical appliance kit groove, after nut crosses two orphan boss, try hard to recommend a little into, until nut the inside contact electrical appliance kit body, nut, the current sheet that confluxes, bolt three dead in line, arc boss plays position-limiting action to nut.
In actual applications, it is intrafascicular that big current terminal is positioned at car load power line, and electrical appliance kit is arranged in car load principal wire bundle, and both are in different wire harness, and auto production line needs both to connect, and namely big current terminal is mounted on electrical appliance kit and confluxes on sheet.
Production line assembles, the intrafascicular big current terminal of car load power line is connected with the electrical appliance kit in car load principal wire bundle, assembling implementation procedure is, big current terminal anti-rotational structure stretches into the sheet anti-rotational structure that confluxes, use and surely turn round instrument, set bolt is tightened, ensures that big current terminal is reliable with the contact of the sheet that confluxes.
Nut demolishing process: band base nut is directly exerted oneself, and overcome orphan boss to after the restraint of nut, push away electrical appliance kit body, electrical appliance kit directly changes respective belt base nut.
Big current terminal mistake proofing design is implemented: big current terminal anti-rotational structure symmetric design, to conflux sheet spacing hole symmetric design, during assembling, anti-rotational structure correspondence is confluxed sheet spacing hole, anti-rotational structure 33 correspondence is confluxed sheet spacing hole 43, anti-rotational structure 32 correspondence is confluxed sheet spacing hole 42, otherwise, cannot assemble.
Electrical appliance kit body design and big current terminal " L " shape structural design adopt integrated design, and after big current terminal is installed, big current terminal vertical portion is positioned at electrical appliance kit sunk part 73, and horizontal component and electrical appliance kit body upper surface are fitted.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalency thereof.
