Description
Technical field
The utility model relates to a kind of Novel clock spring, belongs to the electrical fitting field of vehicle.
Background technology
Along with the development of Domestic Automotive Industry, the development & construction of express highway and the raising gradually of the speed of a motor vehicle, it is more and more important that the safety of automobile becomes.Automobile air-bag system, as the achievement in research of passive satety, because easy to use, Be very effective, cost are not high, is developed rapidly and is popularized.In air bag system, clock spring is between sensor control section and airbag, be the throat of safety system, the wire secure connection problem that what clock spring will solve is between static element and revolving part, ensures that sensor control section is connected all the time with airbag.When automobile normally runs, it makes synchronous rotary along with steering handwheel, between steering handwheel, these two relatively rotating parts of steering-column switch, keep failure-free to be electrically connected, from this view point, in driver airbag system, clock spring is a key, is the primary electron components and parts forming automobile driver gas-bag system.And increase and the development of auto-industry along with automobile consumption diversified demand, steering handwheel control panel is integrated with increasing function, clock spring is transferred to electric signal on steering handwheel panel from vehicle body instrument face plate, thus facilitate driver's manipulation, indirectly improve the safety of manipulation.Now it also assures that the electric signal between steering handwheel button and the functional module such as whole vehicle functions parts, instrument wire harness connects.
Summary of the invention
The utility model object is for overcoming the deficiencies in the prior art, provide a kind of prevent clock spring in use the upper and lower both sides of flat cable by housing wearing and tearing, the floated clock spring strengthening clock spring life-span and housing endurance quality.
The utility model comprises base, upper cover, locking piece, pad, welding keysets, flat cable and protecting cover; Upper cover and base be circular lid structure, and base edge place is provided with bottom wire harness to interface and is dispersed with several mounting hole, for by floor installation at steering column; Base is fixed on car steering tube column, is used to the housing part supporting whole product.Upper cover is buckled on base, and cover rim place is provided with top wire harness to interface; Locking piece is the circular plug-in unit be fastened in upper cover making the upper cover of clock spring and base relatively rotate and not throw off, and its function makes the upper cover of clock spring and base relatively rotate and not throw off; Locking piece inner circle is provided with for the positioning key with car steering tube column mandrel axial location; Gasket shape size cuts into according to upper cover and base intracavity shape and is pasted on upper cover and base intracavity respectively, in order to fall friction and noise within the shape chamber of end flat cable after upper cover, base assembling.Flat cable is made up of overlay film two-sided based on copper strips, and flat cable is surrounded between upper cover and base, distributes in the shape of a spiral, and each exposed section, root copper strips two ends is as conducting joint, and cable gross thickness is 0.14mm, has flexibility, collapsible.Welding keysets adopts brass conductor drawing, conductor outer partial encapsulating insulating material.Welding keysets adopts ultrasonic welding between the exposed copper strips of brass conductor and flat cable both sides.After welding, the contact pin that switching welded plate exposes is by flat cable conducting.Flat cable is pressed anticlockwise direction around upper cover and is wound around.Protecting cover comprises square piece and is positioned at the tongue piece of side, and all adopt PC+PP injection moulding to make, tongue piece is grown and good springiness, and protecting cover is divided into upper cover protecting cover and base protecting cover two kinds; Upper cover protecting cover square piece is loaded on and covers, and the flat cable in upper cover protecting cover tongue piece double faced adhesive tape and upper cover is pasted, and is synchronized with the movement, prevents flat cable inflection with flat cable.Base protecting cover square piece is loaded on base, forms one for limiting the crack of cable position, in order to protect flat cable between base protecting cover tongue piece and base inner wall.Fixing screw is fixed between upper cover and base, utilizes location, this gap centering between upper cover and base, prevents the clock spring number of turns from misaligning, make clock spring clockwise direction and anticlockwise direction effectively rotate circle equal.
The floated clock spring of the utility model is after entrucking, upper cover does not contact with base, guarantee flat cable by the extruding of clock spring housing, friction, and upper cover and base does not does not also wear and tear, reduce the noise that between housing, phase mutual friction produces, effectively improve housing endurance quality and product life.
