Abstract
A connector for a wet-type double clutch automatic transmission comprises a housing, and an anti-capillary guide line and a terminal both arranged in the housing, wherein the anti-capillary guide line is connected with a bottom of the terminal. The bottom of the terminal is fixedly pasted with the housing. A top surface of the housing is fixedly pasted with the terminal. The anti-capillary guide line comprises a copper core and an insulation rubber layer wrapped outside the copper core, and a sealant layer is arranged between the copper core and the insulation rubber layer. The sealant layer is silica gel. An oil leaking problem of a glue-pouring-type connector of the wet-type double clutch automatic transmission is effectively solved, and the connector is more strong in sealing property and more reliable.
Description
Technical field
The utility model relates to a kind of device of automotive transmission technical field, specifically is a kind of connector for the wet-type double-clutch automatic speed-change device.
Background technology
DCT speed changer (Dual Clutch Transmission).The DCT speed changer is the automatic transmission that adopts double clutch, except the comfortableness of the flexibility that has manual transmission and automatic transmission, can also provide unremitting power output.This technology is used at masses' product.After numerous generals' golf GTI and the TT of Audi brought China into greatly, auto enterprises had also begun to recognize the advance of DCT speed changer.
On stream, connector oil impregnate problem can't solve as persistent ailment all the time effectively fully.At this problem, attempted increasing positive millet cake glue, change glue, strict control technology is made, and changes various methodologies such as terminal silver plating process, can't reach gratifying effect all the time.
Find through the retrieval to prior art; Chinese patent literature CN102501811A; open day 2012-6-20; put down in writing a kind of water-impervious protection structure of vehicle signal wire harness; comprise the signal wire harness; the insulated enclosure pipe; elastic collar and connector; the signal wire harness is electrically connected with connector; be provided with the insulated enclosure pipe in the outside that the signal wire harness is connected with connector; the insulated enclosure pipe box is contained in outside the signal wire harness; elastic collar is installed on the outer wall of insulated enclosure pipe; be provided with hot-forming rubber seal piece at insulated enclosure pipe and holding wire beam entrance junction, the rubber seal piece is wrapped in the entrance junction of insulated enclosure pipe and signal wire harness wherein.But the prior art is only applicable to the waterproof field of signal wire harness, can't be used for speed changer inside.
The utility model content
The utility model proposes a kind of connector for the wet-type double-clutch automatic speed-change device at the prior art above shortcomings, and sealing is strong, effectively solves the fluid seepage.
The utility model is achieved through the following technical solutions, and the utility model comprises: housing and be arranged at wherein aforesaid anti-capillary lead and terminal, wherein: the bottom connection of anti-capillary lead and terminal.
Described anti-capillary lead comprises: copper core and wrap up its outside insulating cement cortex, wherein: be provided with sealant layer between copper core and the insulating cement cortex.
Described sealant layer is silica gel.
The bottom of described terminal and the inside of housing are adhesively fixed.
Upper surface and the terminal of described housing are adhesively fixed.
At encapsulating type connector oil impregnate problem, be the core seepage through verification experimental verification for the oil pressure seepage.The mechanism of core seepage is exactly capillarity in fact.Owing to exist the gap all the time between lead copper core and the insulating cement cortex, constituted capillary pipe structure.And gear-box lubricating oil is to soak into liquid concerning lead.In capillary insert to soak into liquid, the intraluminal fluid face rose, and gearbox has interior pressure simultaneously, formed pressure reduction with the outside, had further strengthened capillarity, made fluid flow into glue layer, again by the gap leakage between terminal and the glue to the outside.
The utility model solves wet-type double-clutch automatic speed-change device encapsulating type connector oil impregnate problem effectively, and its sealing property is stronger, and is more reliable.
