Abstract
The cable path sealing apparatus is known, it comprises a plurality of cable paths for communicating and guiding the connection cables into a housing and sealing bodies disposed in the cable paths; and it has the disadvantage that the sealing effect must be kept by spring. The apparatus in the invention is simplified, the member quantity is reduced and the manufacturing cost is reduced consequently. According to the present invention, a sealing body (4) is integrally connected with at least one connection cable (2), and has at least one side protruding portion (5) for anchoring the sealing body (4) in the cable path (3).
Description
Technical field
The present invention relates to a kind of device for cable path sealing.
Background technology
By the known a kind of device for cable path sealing of DE 197 28 370A1, this device has: a plurality of cables through, for stube cable is run through and is directed to housing; And seal, these seals are arranged in cable through and around stube cable setting.Shortcoming is: need spring to maintain the sealing function on cable through.Between stube cable and each seal, may occur leaking.
Summary of the invention
According to the present invention proposes a kind of device for cable path sealing, this cable through is at least one stube cable, in particular for contacting the stube cable of the sensor element of exhaust sensor, this device is with at least one cable through of housing, described cable through is for running through at least one stube cable to be directed in housing, this device also has seal, sealing body is arranged in described cable through and around described at least one stube cable setting, it is characterized in that, described seal is connected integratedly with described at least one stube cable and has at least one for described seal being anchored on to the side protuberance (Hinterschneidung) of described cable through.
According to the device for cable path sealing of the present invention, have advantages of like this, this device is simplified with respect to prior art, because can save spring and thereby reduce manufacturing cost.This realizes in the following manner: seal is connected integratedly with described at least one stube cable and has at least one for seal being anchored on to the side protuberance of cable through.
To above-mentioned according to the favourable improvement project of device of the present invention with to improve be feasible.
According to a kind of favourable execution mode, described seal is injected on described at least one stube cable.In simple mode, obtain being tightly connected between stube cable and seal thus, thereby do not need sealing force to seal this position.Between stube cable and seal, do not leak.
Particularly advantageously, described seal surrounds all stube cables.Cable through and sealing thereof are simplified by this way, because stube cable is not individually but is jointly introduced in cable through.
In addition advantageously, described seal is pressed in cable through, because can form and be tightly connected between seal and cable through by this way.The side protuberance of seal extend in the elastomeric material that surrounds cable through and prevents that seal is drawn out from cable through, until reach predetermined pullout forces.
Very advantageously, described seal is made by pottery, because also obtained by this way the electric insulation of the twisted wire of stube cable.
Favourable also have, and it is conical and towards enclosure interior convergent, because can make by this way seal insert cable through from outside that described cable through is configured to.
In addition advantageously, described cable through is arranged in a union body, and this union body is arranged in the shell nozzle of housing.This union body for example wedging in shell nozzle.Union body is made by elastomeric material, for example plastics, makes to seal physical efficiency and is anchored in cable through in locking manner with simple mode force closure and/or shape.
Accompanying drawing explanation
One embodiment of the present of invention are simplified in the accompanying drawings and are illustrated and elaborate in the following description.
Fig. 1 illustrates according to the device for cable path sealing of the present invention.
Embodiment
Fig. 1 illustrates the device shown in a kind of simplification with cutaway view, and this device is for cable path sealing, and this cable through is for stube cable, for example, for connecting the stube cable of the sensor element of exhaust sensor.
This device comprises housing 1, and at least one stube cable 2 leads in this housing by least one cable through 3.For technical reason, cable through 3 need be configured to seal, the in the situation that of exhaust sensor, for avoiding the so-called benchmark air chamber of housing 1 to be subject to polluting and causing thus distorted signals.For this reason, be provided with a seal 4 in cable through 3, sealing body surrounds described at least one stube cable 2 so that sealing.
According to the present invention's regulation, seal 4 is connected integratedly with described at least one stube cable 2 and has at least one for seal 4 being anchored on to the side protuberance 5 of cable through 3.Seal 4 injection mouldings or be otherwise molded on described at least one stube cable 2 and surround this stube cable in a part for the axial length of described stube cable.According to this execution mode, at least two even all stube cables 2 of (for example four) stube cable 2 all pass seal 4.By realizing and being tightly connected between described at least one stube cable 2 of being molded into of seal 4 and seal 4.According to this execution mode, seal 4 surrounds all stube cables 2 of this device, for example four stube cables 2.
According to this execution mode, seal 4 has conical section 4.1 and cylindrical sector 4.2, and wherein, seal 4 is inserted in cable through 3 previously with conical section 4.1.Side protuberance 5 is for example by step-like protruding 8 formation between conical section 4.1 and cylindrical sector 4.2.Cable through 3 is for example configured in union body 9, this union body be arranged in the shell nozzle 10 of housing 1 and with housing 1 wedging.It is conical and towards enclosure interior convergent that cable through 3 is for example configured to.Seal 4 is forced in cable through 3, and wherein, side protuberance 5 enters in the elastomeric material that surrounds cable through 3 and grappling seal 4 by this way.Cable through 3 is configured to: be less than the size of seal 4, the sealed body 4 of cable through 3 flexibly expanded and formed extruding to connect.Seal 4 is for example by plastics or pottery with make, and union body 9 is made of plastics.In the situation that seal 4 is formed by pottery, stube cable 2, at seal 4 built-in electrical insulations, makes only to exist there the insulated twisted wire of pottery by electric insulation.Ceramic seal body is sintered.
Housing 1 can be a part for exhaust sensor, and this part has sensor element 14, and this sensor element 14 remains in sealed packet 15.By this sensor element 14, can obtain the physical quantity of gas, for example oxygen concentration.Sensor element 14 has at least one and connects contact 16, and this connects contact and for example by unshowned contact tongue, contacts with described at least one stube cable 12 of cable passage.Contact between contact tongue and sensor element for example realizes on force closure ground.Contact tongue welding or amalgamation are being passed on the twisted wire of seal 4.
