Description
Technical field
The present invention relates to technical field of automobile parts, particularly relate to a kind of pad.
Background technology
In automobile circuit design, be usually connected with battery terminal negative by wire harness by the major metal part assemblies such as the vehicle frame on car load panel beating and chassis thereof, the negative pole being used as vehicle circuitry uses.Usually on car load panel beating or vehicle frame, be provided with multiple installing hole carrying out being connected with vehicle circuitry negative pole, these installing holes are normally welded with the female circular hole of the back of the body, can be fixed on panel beating by the cathode wiring plate on wire harness by bolt, these installing holes are commonly referred to bonding dots.
Vehicle body sheet metal or the large assembly of vehicle frame are through painting electrophoresis, the process of the technique such as to spray paint or through long-term transport and placement, the metal surface of bonding dots or carry on the back female interior threaded surface often easily by electrophoretic paint, paint, various impurity, greasy dirt, dust, the attachments such as rust staining, when the cathode wiring plate on bonding wire harness is arranged on after on bonding dots, these impurity will hinder current lead-through, make the cathode wiring plate on bonding wire harness can not realize current lead-through with vehicle body sheet metal or vehicle frame, when bonding lug plate is installed, construction bolt and bonding sheet or can not be carried on the back and femalely form reliable and good Metal Contact with plates of automobile, cause circuit turn-on bad or can not conducting.In automobile making and run in use procedure the fault occurred and have and all cause loop cannot conducting and causing by this kind of bonding dots loose contact greatly, some circuit function be indirectly caused not continue, reliable, stable realization.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is: provide a kind of reliable and stable pad contacting, ensure the reliable conducting of loop current that can improve cathode wiring plate and bonding dots metal.
(2) technical scheme
For solving the problem, the invention provides a kind of pad, this pad comprises: plate-like body, and described plate-like body edge is provided with extension, and described extension and described plate-like body place plane are in the angle set.
Preferably, described plate-like body is provided with centre bore.
Preferably, described extension is uniformly distributed in described plate-like body edge.
Preferably, the thickness of described extension is from reducing gradually to away from described edge direction with described plate-like body edge
Preferably, described extension is arranged at the whole edge of described plate-like body.
Preferably, the edge of described extension is irregular curve.
Preferably, the edge indentation of described extension.
(3) beneficial effect
Pad of the present invention, launches to the periphery because extension can be out of shape under the effect of extruding force, thus the paint film of contact-making surface or impurity layer is drawn and remove, and greatly can improve cathode wiring plate and contact with the reliable and stable of bonding dots metal, ensure reliable On current; Gasket construction is simple, convenient, reliable, and has certain anti-bolt rewind function, and production and processing is convenient, with low cost, in car load assembling process, can not produce added influence to mounting process.

Embodiment
The present invention propose pad, by reference to the accompanying drawings and embodiment be described in detail as follows.
For the bonding pad that bonding dots is special, this pad is applicable to the installation situation of position, all bonding holes on vehicle body sheet metal, comprise panel beating in enging cabin to be connected with the bonding on panel beating, automobile chassis in driver's cabin, for ensureing that automobile bond point realizes absolute Metal Contact, and then realize reliable current conducting.As shown in Figure 1, bonding pad 3 according to one embodiment of the present invention comprises: the centre bore 3-2 of the geometric center setting of plate-like body 3-1 and plate-like body 3-1, plate-like body 3-1 edge is provided with extension 3-3, and extension 3-3 and plate-like body 3-1 place plane are in the angle set, only need ensure that, not in a plane, the concrete size of angle is not as limitation of the present invention.
In pad of the present invention, extension 3-3 can be arranged at the whole edge of plate-like body 3-1, as Figure 1-3; Also evenly or unevenly can be distributed in the edge (being namely arranged on the local edge of plate-like body 3-1) of plate-like body 3-1, (be illustrated as and be uniformly distributed) as shown in Figure 4.In addition, the edge of extension 3-3 can be rule or irregular curve.
In present embodiment, the plate-like body 3-1 of pad 3 is rounded, centre bore 3-2 is the concentric circular port be arranged on plate-like body 3-1 with plate-like body 3-1, extension 3-3 is arranged at the whole edge of plate-like body 3-1, and its edge contour preferably indentation, make whole pad 3 in padmasana, the whole week edge of i.e. plate-like body 3-1 arranges extension 3-3, the angle of extension 3-3 and plate-like body 1 place plane is obtuse angle, and the edge line of extension 3-3 is in having multiple sharp tip-angled shape, as seen in figs. 5-6.
As shown in Figure 7, in use, this bonding pad 3 is coordinated with the cathode wiring plate 2 on flange construction bolt 1 and bonding wire harness, first cathode wiring plate 2 is set on the screw rod of flange face construction bolt 1, and then put bonding pad 3, make cathode wiring plate 2 between bonding pad 3 centre bore 3-2 surface and the flange face of construction bolt 1, make the wedge angle of the extension 3-3 of bonding pad 3 towards the installed surface (around bonding dots panel beating or surface of steel plate 5) around bonding dots, namely the angle of extension 3-3 and installed surface is acute angle, so just can ensure that cathode wiring plate 2 and construction bolt 1 and bonding pad 3 realize Metal Contact can On current, and bonding pad 3 can not be driven constantly to rotate together when construction bolt 1 is tightened, then construction bolt 1 is screwed in the back of the body mother 6 of bonding spot hole position, along with construction bolt 1 is urgent gradually at bonding dots, the flange face of construction bolt 1 moves closer to installing hole surface, indirect promotion cathode wiring plate 2 and bonding pad 3 close to bonding dots surface, bonding pad 3 is under construction bolt 1 screws the contention effect of power, the wedge angle of its extension 3-3 is flattened to surrounding gradually to launch, the angle of extension 3-3 and plate-like body 3-1 place plane reduces (the integral thickness size of bonding pad 3 reduces gradually) gradually, as Figure 8-9.In this process, because extruding is born on bonding pad 3 two sides, all the time contact with the paint film on panel beating around bonding dots or vehicle frame steel plate 5 surface or impurity layer 4 in the process that the sharp end of extension 3-3 wedge angle launches in extruding, and then paint film or impurity layer 4 strokes are removed, such bonding pad 3 just realizes reliable Metal Contact with the metal material such as installed surface panel beating or vehicle frame steel plate 5, indirectly enables cathode wiring plate 2 and bonding dots metal realize current lead-through.
In the pad of present embodiment, for making extension 3-3 paint film or impurity layer 4 strokes be removed better, the thickness of extension 3-3 can from reducing gradually to the direction away from edge with the edge of plate-like body 3-1.
It should be noted that, the quantity etc. of the wedge angle that the shape of plate-like body 3-1 mentioned above, centre bore 3-2 and the edge line of extension 3-3 have is and is applicable to different installation situation and preferred, at this not as limitation of the present invention.
Above execution mode is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
