Detailed description of the invention
Fig. 1 shows the schematic three dimensional view of connector assembly 100, wherein coordinates auxiliary sliding part 200 to be illustrated inIn connector shell 101, be arranged on open position. Connector shell 101 is provided with cable joint-box 102, with by cableBe connected to connector assembly 100. In Fig. 1, can see, coordinate auxiliary sliding part 200 to there is roughly U-shapedShape, and two actuating legs 203 that are provided with base portion 201 and generally perpendicularly give prominence to from described base portion. As rightIn those skilled in the art, will be clear that, and in different embodiments, coordinate auxiliary sliding part only can be provided withOne activates leg 203 or is provided with plural actuating leg 203, and connector shell 101 will be established in these casesBe equipped with one or more corresponding hole 103 (referring to Fig. 2).
Fig. 2 shows the connector shell 101 of Fig. 1 from different visual angles, wherein in the figure, coordinate auxiliary sliding part200 have been removed. As seen in the figure, connector assembly 100 is provided with containment member 301 and anotherOptional potted component 307, these containment members are arranged on the hole 103 of connector shell 101, at connector caseWhen body is connected to panel 700 as shown in following Fig. 6, sealing element is used for seal connector shell 100 and panelPossible transition region in the middle of 700. In illustrated embodiment, two containment members 301 and optional potted component307 are formed as a body component of black box 300, and sealing assembly is the single note that is attached to connector shell 101Plastic. As to those skilled in the art will be clearly, containment member 301 and sealing in different embodimentsElement 307 can be attached or not be attached to the single parts of connector shell 101. Black box 300 and sealing structurePart 301 and potted component 307 can be made up of rubber, plastics, silicon or the similar material that is suitable for sealing purpose.
In Fig. 2, can see, containment member 301 is with the form setting of sealing ring, and these sealing rings are around connectorThe hole 103 of housing 101 arranges and partly extends in hole. Hole 103 is guide groove 119 (referring to Fig. 3) preferablyOpening, and extend in hole 103 by part, containment member 301 is arranged on the inner surface of guide groove 119.In different embodiments, these containment members 301 can differently be shaped, for example, and around rounding or difform holeArrange. Similarly, containment member 301 can extend in hole 103 farther or not farly. But, importantly,By extending at least in part in hole 103, containment member 301 is provided with at least one parallel sealing surface thus311, that is, be roughly parallel to and activate the direction of insertion 601 that leg 203 inserts connector shell 101 and arrange. As schemedIn 2, can see, sealing surface comprises rounded corners and roughly consistent with the stage portion in hole 103. EvenThe accurate shape on parallel sealing surface 311 is not very important for the present invention, and advantageously, can not in sealing surfaceHinder and activate in leg 203 patchholes 103 and can provide to the corresponding actuating leg sealing surfaces that activates leg 203 simultaneouslyThe optimum sealing contact of 205 (referring to Fig. 1).
In addition, in Fig. 2, can see, containment member is provided with vertical seal surface 313, these vertical sealSurface be arranged in the plane that is approximately perpendicular to direction of insertion 601 (that is, as shown in Figure 1, roughly along direction 603,605 extend). In the time coordinating auxiliary sliding part 200 to be arranged on its closed position, these vertical seal surfaces 313Be suitable for contacting with base portion sealing surfaces 207 (referring to Fig. 1) sealing. Thus, parallel sealing surface 311 is with vertical closeThat envelope surface 313 provides is favourable, L shaped sealing roughly, and sealing portion allows for hole 103 and connector caseThe optimum sealing of the inside of body 101. In Fig. 3 and Fig. 4, can see best by activating leg sealing surfaces 205 and baseThis favourable L shaped sealing that portion's sealing surfaces 207 forms. With the situation on parallel sealing surface 311 similarly, hang downStraight sealing surfaces 313 needs not to be smooth, but these surfaces also can be arranged to rounding shape or be provided with in additionSealed step portion etc. contact to improve with the sealing that coordinates the corresponding sealing surfaces of assisting sliding part.
In Fig. 3 and Fig. 4, coordinate the base portion 201 of auxiliary sliding part 200 to be shown as roughly flat board, activate leg203 generally perpendicularly extend to and are formed by the madial wall 111 of connector shell 101 and lateral wall 113 from this flat boardIn guide groove 119. Due to the even shape of base portion 211, coordinating auxiliary sliding part 200 to be arranged on as shown in the figure itThe complete coverage hole 103 of base portion when closed position. This is favourable, because planar base portion 201 provides separately for eachThe closing seam surface in single hole 103 (as for example with the situation phase of the single large sealing ring of arranging around two holes 103Instead), and planar base portion 201 be also provided for the mechanical protection in vertical seal surface 313 and hole 103. Shown inIn embodiment, planar base portion is provided for the closure member of the almost form fit of connector shell 101, if connectedDevice assembly is for example moved in the maintenance period, and this closure member provides optimum mechanical stability so.
As seen from Fig. 4, activate leg sealing surfaces 205 and be arranged in the near-end shank 211 that activates leg 203, byThis is adjacent with base portion sealing surfaces 207. Therefore, activate leg sealing surfaces 205 and 207 formation of base portion sealing surfaces greatlyCause L shaped matched seal portion, to provide and to be formed roughly by parallel sealing surface 311 and vertical seal surface 313The optimum sealing contact of L shaped sealing.
In order further to improve the sealing effectiveness of above mentioned sealing surfaces, activate leg 203 and be also provided with those widened sections217, this those widened sections and sealing ring wedging in actuating leg inserts described guide groove 119 time. As energy in Fig. 3 and Fig. 4See, therefore activate on the parallel sealing surface 311 that leg sealing surfaces 205 is compressed against containment member 301, withImprove the sealing contact between these sealing surfaces.
As mentioned in background technology above, if in the time that connector coordinates or as coordinated auxiliary cunning in this situationWhen moving part 200 inserts in connector shell 101, containment member is compressed along the direction that is parallel to direction of insertion. This pressureContracting causes the restoring force of the self-compressed containment member in source, and this restoring force hinders and coordinates or insertion process. In this respect, flatRow sealing surfaces 311 is arranged along ideal orientation: when activating leg 203 while being inserted into, parallel sealing surface only can be along verticallyDirection in direction of insertion 601 is pushed by activating leg 302. Therefore, by pushing, parallel sealing surfaces 311 causesThe also possible restoring force that is derived from the compression of containment member 301 only can be along playing work perpendicular to the direction of direction of insertion 601With, and therefore do not hinder the insertion that coordinates auxiliary sliding part 200.
Coordinate sealing and/or the mechanical connection of auxiliary sliding part 200 to connector shell 101 in order to improve, or mustThe words of wanting to be derived from containment member 301 and (for example, to pass through along the compression of the direction that is parallel to direction of insertion 601 in order to compensateBase portion sealing surfaces 207 is pressed against to the compression that cause on vertical seal surface 313) possible restoring force, containment member301 and activate corresponding locking-sealing device 303,215 that leg sealing surfaces 205 advantageously comprises separately. These locksFixed-sealing device 303,215 shown in preferred embodiment in be embodied as and be arranged on the parallel close of containment member 301Seal the locking-sealing recess 303 in surface 311 and be arranged on the locking-sealing protuberance 215 activating on leg 203.In the embodiment shown, an only side of each actuating leg 203 is provided with locking-sealing protuberance 215, but,In different preferred embodiments, the opposite side or all sides that activate leg 203 also can be provided with locking-sealing protuberance215. As those skilled in the art can obtain from Fig. 3 and Fig. 4, auxiliary cooperation sliding part 200 is being moved into its passWhile closing position, locking-sealing protuberance 215 is set in locking-sealing recess 303, will coordinate thus auxiliary sliding part200 are locked in its closed position. Thus, preferably, these locking-sealing devices are fulfiled favourable dual-use function:Auxiliary cooperation sliding part 200 is locked in its closed position by they, compensates thus above mentioned possible restoring force;And they advantageously can improve parallel sealing surface 311 and activate the sealing effectiveness of leg sealing surfaces 205.
As seen in Fig. 3 and Fig. 5, for auxiliary cooperation sliding part 200 is locked in to its closed position, activateLeg 203 is also provided with other locking devices, these locking devices comprise be in the example shown arranged on activate leg 203On locking tongue 221 and be arranged on the corresponding locking recess 115 in the madial wall 111 of connector shell 101. AsIn Fig. 5, can further see, coordinate auxiliary sliding part 200 to be provided with cam groove 225 and connector shellBe provided with respective cams insertion groove 105,107,109. Due to the major function of the auxiliary sliding part of such cooperation forThe file that those skilled in the art for example quote from above-mentioned background technology is known, therefore will only describe brieflyThis function. As those skilled in the art will admit, when coordinating auxiliary sliding part 200 to be arranged on its open position (alsoAnd two cam grooves 225 of shown actuating leg 203 align with cam insertion groove 105 and 107) time, cam is recessedGroove 225 is suitable for receiving matching connector in the time of connector assembly 100 and matching connector 500 (referring to Fig. 6) cooperation500 respective cams pin. When coordinating auxiliary sliding part to move towards its closed position (as Fig. 5 institute from its open positionShow) time, cam pin moves along cam groove, thus towards connector shell 101 tractive matching connectors 500.Thus, activate leg 302 and there is actuation function. But, as for those skilled in the art will be clearly, coordinate auxiliarySliding part 200 can only be provided with one and activate leg 203 or plural actuating leg 203. In addition, coordinate and assistSliding part can be provided with the leg without actuation function, and this leg will only be used for by auxiliary cooperation sliding part 200 suitablyGuiding enters in connector shell 101.
As seen in this figure, at cam groove place, containment member is not set. Owing to providing sealing at 103 places, holeThis seal concept of member 301, in the inside of connector shell (such as at cam groove 225 places or andCorresponding cam pin place) the unnecessary seal member that exists, the potted component of even now can be configured to for additional peaceQuan Xing. This is favourable because such inner seal member conventionally manufacture, assemble complexity and hinder connector andCoordinate the assembling of servicing unit.
Fig. 6 shows the connector assembly 100 that is coupled to corresponding matching connector 500 through the hole in panel 700.Under this mated condition, potted component 307 (referring to Fig. 1 to Fig. 4) contacts with the respective surfaces sealing of panel 700.Panel 700 can be for example a part for door for passenger car or a part for the car body of passenger car. But, preferablyThe connector assembly 100 that also comprises matching connector 500 can certainly be used for different application.
