With reference now to accompanying drawing,, cover piece 1 according to the present invention is designed for sealing and is arranged on the aperture 101 in the support members 100 such as such as engine cylinder-body.Cover piece 1 comprises housing 2, fastening lug 3 and breech lock 4.
Housing 2 comprises Integral flat-plate 20, is extended with substantially vertical and to be accepted in 101Zhong skirt section, aperture 21 with flat board 20 from dull and stereotyped 20.See from above, dull and stereotyped 20 have roughly trapezoidal shape.Dull and stereotyped 20 have the cavity of the downward orientation that has formed lug boss 22 on surface thereon and the receiving space (invisible) below its soffit.This cavity can be received and for example be arranged on the lug boss of receiving the sensor (not shown) in space.Receive space to make dull and stereotyped 20 lateral open via downward unlimited passage 24, passage 24 can be received the power cable and/or the communications cable that for example engine speed sensor are connected with the electronic entity of motor vehicles.Passage 24 is defined by resilient portion 25 in bottom, and resilient portion 25 can be clamped cable tightly.Therefore, skirt section 21 is interrupted in the position relative with passage 24 and the breech lock that will be described below after a while.Skirt section 21 is for guaranteeing the correct location of cover piece 1 with respect to aperture 101.Nature can be understood, and cover piece 1 can have any other suitable shape.The flange limit of cover piece 1 is arranged on the first lock-in edge 23 of the connecting portion between skirt section 21 and dull and stereotyped 20.The first lock-in edge 23 is extended on the periphery of whole housing 2, and at the supporting plane P (it is schematically illustrated in Fig. 1, Fig. 2 and Fig. 4) of the edge upper limit fixed shell 2 in the aperture 101 of support member 100.The extension of the first lock-in edge 23 is set to like this: in the time that skirt section 21 is received in aperture 101, this extension is supported on the top, edge in aperture 101.The first lock-in edge 23 can be continuous or discontinuous.In the example shown, skirt section 21 is also provided with two fastening lugs 3, and these two fastening lugs 3 are arranged on the edge contrary with the edge that is provided with breech lock 4 of housing 2.These fastening lugs 3 extend in the mode that is roughly parallel to supporting plane P in the plane that is different from supporting plane P, the edge in the aperture of support member 100 101 can be received in to the fixed engagement region between fastening lug 3 and the first lock-in edge 23 to limit.Therefore,, before the edge in aperture 101 is turned round in the whole length for being shelved on the first lock-in edge 23, cover piece 1 can present heeling condition in aperture 101, so that one of the edge in aperture 101 is bonded between fastening lug 3 and the first lock-in edge 23.Can understand equally, cover piece can have quantity and exceed the breech lock of and/or do not have any fastening lug on one or more sides.
The edge that the edge with having fastening lug 3 of housing 20 is contrary and the opening 5 of housing 20 are tangent.Two pivot axis C transverse seals that roughly similarly coaxial torque rod 6 forms that opening 5 is extended in breech lock 4 both sides.In this example, opening 5 has essentially rectangular shape.But the edge relative with pivot axis C of opening 5 has two discontinuous portions that limit separately clearance portion 50 and fixed stop 51, their function will describe in detail after a while hereinafter.Discontinuous portion is arranged in the pivotal path of breech lock 4, and therefore fixed stop 51 is separated by clearance portion 50.According to unshowned embodiment, clearance portion can be arranged on the outside of fixed stop, or can alternately arrange fixed stop and clearance portion.In the horizontal plane of the upper surface of housing 20, each fixed stop 51 limits the V-arrangement tangent with the edge of opening 5, and the opposed facing branch of opening 5 comprises clinoplain 52 or circular flat, and the function of circular flat will be described hereinafter after a while.Discontinuous portion is separated by projection 53 on the upper surface of housing 20, and projection 53 is designed to form the first retainer of restriction breech lock 4 pivotables.
Breech lock 4 comprises the general planar phalangeal palte 40 of rectangular shape, and phalangeal palte 40 can receive the pressure of user finger so that this phalangeal palte by manual bias voltage towards opening 5 and make breech lock 4 pivotables.Phalangeal palte 40 can have the groove 49 (it is visible in Fig. 1) of the slip of the lug of restriction bias voltage and strengthening phalangeal palte 40.Therefore, breech lock 4 can be between unlocked position and latched position pivotable, breech lock 4 does not hinder the mobility of cover piece 1 with respect to support member 100 at unlocked position, and breech lock 4 cooperates that with housing 20 cover piece 1 is locked on support member 100 in latched position (particularly by means of fastening lug 3 and the first lock-in edge 23).Phalangeal palte 40 directly and pivot axis C tangent, and be arranged in and the plane of pivot axis C almost parallel.The free edge relative with pivot axis C of phalangeal palte 40 is tilted tongue 41 and extends.Phalangeal palte 40 limits first par 400 that can receive user's finger pressure, inclination tongue limits the second par 401 of the phalangeal palte that can receive equally user's finger pressure, in Fig. 4, can find out the first smooth finger-like board 400 and the second smooth finger-like board 401 second angle beta of being separated by.Inclination tongue 41 can cooperate to limit breech lock 4 pivotables with projection 53 and exceed latched position.Projection 53 can tilt towards inclination tongue 41 in complementary mode.Projection 53 can be strengthened by two flanks 54 that projection 53 is connected with housing 20.Therefore, projection 53 and inclination tongue 41 form the complementary shape that limits the first retainer.In the time of their butts, projection 53 and inclination tongue 41 form with respect to supporting plane P tilt abutment plane P'(its in Fig. 4, schematically show).The unlocked position specifically illustrating in Fig. 3, phalangeal palte 40 is along extending above housing 20 with skirt section 21 rightabouts.The latched position specifically illustrating in Fig. 4, phalangeal palte 40 is comprised in the thickness range of housing 20.
Breech lock 4 also comprises the bending hook portion 42 that has formed the second lock-in edge 7.In the time that breech lock 4 is in the unlocked position, hook portion 42 can not extend outwardly beyond skirt section 21, when breech lock 4 is during in latched position, hook portion 42 can make the second lock-in edge 7 horizontal expansions exceed skirt section 21, with from below by the edge locked in aperture 101 between the first lock-in edge 23 of housing 20 and the second lock-in edge 7 of breech lock 4.Hook portion 42 and phalangeal palte 40 are arranged on the both sides of the pivot axis C of breech lock 4.Therefore,, in unlocked position and latched position, hook portion 42 is extended below housing 20 in a side identical with skirt section 21.In the example shown, hook portion 42 has the unlimited V-arrangement shape being formed by the first smooth hook portion 420 being connected with pivot axis C by the second smooth hook portion 421.In Fig. 4, can find out the first smooth hook portion 420 and the second smooth hook portion 421 first angle [alpha] of being separated by.The first angle [alpha] is substantially equal to the second angle beta, so that the first smooth hook portion 420 and finger-like board 400 also almost parallel each other of almost parallel and the second smooth hook portion 421 and finger-like board 401 each other.
Breech lock 4 also comprises and is arranged on the both sides of phalangeal palte 40 and at almost parallel each other and two release fins 45 that roughly extend from pivot axis C in the plane vertical with supporting plane P with pivot axis C.According to unshowned embodiment, release fin can tilt with respect to pivot axis and/or relative to each other.The mode that breech lock 4 also comprises being approximately perpendicular to pivot axis C extends and has two snap close lugs 44 of the length that is greater than the distance from pivot axis C to fixed stop 51 of counting from pivot axis C from pivot axis C.In addition, snap close lug 44 is set to when breech lock 4 is between its locked when pivotable in the path of the fixed stop 51 in being formed by opening 5.Therefore, fixed stop 51 can not be passed through in the end of snap close lug 44 in the situation that not deforming.The end of snap close lug 44 becomes certain inclination angle, to cooperate with the clinoplain 52 of fixed stop 51, thereby makes 44 lateral deformations of snap close lug, until they are relative with clearance portion 50 and can pass through fixed stop 51.Therefore, by phalangeal palte 40 during towards opening 5 manual bias voltage, realize snap close lug 44 between unlocked position and the latched position of breech lock 4 by the motion of fixed stop 51 by the lateral deformation of each snap close lug 44.In the example shown, due to the setting of fixed stop 51 and clearance portion 50, snap close lug 44 is biased toward one another.After moving through fixed stop 51, snap close lug 44 engages with fixed stop 51, to prevent that breech lock 4 from turning back to its latched position.Therefore, snap close lug 44 and fixed stop 51 form the device of snap close breech lock 4 in its latched position.Release fin 45 with respect to snap close lug 44 with at a distance of the angled skew of the more remote mode of housing 20.Therefore, when supporting plane P is during in level, skirt section 20 is arranged on the below of described supporting plane P, and release fin 45 extends above snap close lug 44.After moving through fixed stop 51, in the latched position of breech lock 4, still can approach (contact) release fin 45 from the opposite side of housing 20 (, a housing 20 tops side relative with snap close lug 44).Therefore, release fin 45 easy operatings.
Between the end of snap close lug 44 and the end of release fin 45, be provided with material and remove portion 46 (it is shown in Fig. 3 and Fig. 4).Material removes portion 46 can make release fin 45 transverse bending, and this will be described in more detail below after a while.In addition, release fin 45 is rigidly fixed on snap close lug 44 and with respect to pivot axis C and connects in the mode of elastically deformable.Therefore, can cause the lateral deformation of release fin 45 to the laterally manual bias voltage of release fin 45, thereby cause the lateral deformation of snap close lug 44, thereby finally make the end of each snap close lug 44 relative with corresponding clearance portion 50, and can make snap close lug 44 by fixed stop 51.Material removes portion 46 can make release fin 45 transverse bending, and not with the EDGE CONTACT of inclination tongue 41.Release fin 45 and clearance portion 50 forms tripper that can release breech lock 4, so that breech lock 4 can move to its unlocked position from its latched position.In order to promote the lateral deformation of release fin 45 and snap close lug 44, lateral column 43 and phalangeal palte 40 separate at the position of pivot axis C butt and towards their free end.In addition, the free end of each release fin 45 is provided with and stretches out edge 47, when release fin 45 being pressed together user and pulling breech lock 4 to carry out release breech lock 4 (this will be described below after a while), stretch out the slip of edge 47 limited subscriber fingers.
Each lateral column 43 is provided with protuberance 48, protuberance 48 horizontal expansion on the side contrary with phalangeal palte 40, and therefore, in the pivotable process of breech lock 4, protuberance 48 is arranged in the path at the edge in aperture 101.Therefore, the distance between the end of two protuberances 48 is greater than the width of opening 5.Protuberance 48 is also set to not with the EDGE CONTACT in aperture 101 until breech lock 4 has arrived its latched position.Therefore, the edge in these protuberances 48 and aperture 101 has formed and has limited the second retainer that breech lock 4 pivotables exceed latched position.
Breech lock 4 and housing 20 are connected to each other by the torque rod 6 of being arranged to directly to aim at and limit with the edge of housing 20 pivot axis C.These torque rod 6 elastically deformables so that their twisting action can follow breech lock 4 around pivot axis C the pivotable between its unlocked position and latched position.Therefore, cover piece 20 can be fabricated to for example single moulded parts by molded acquisition.Therefore, cover piece 1 is easy to produce.Because this cover piece does not need assembling, therefore reduce and to have lost the risk of parts and easy to use.In order to allow the demoulding of cover piece 1, phalangeal palte 40 limits the first smooth finger-like board 400 with the first smooth hook portion 420 almost parallels.Therefore, breech lock 4 can occupy unlocked position, and at this unlocked position, the first smooth hook portion 420 and finger-like board 400 are substantially vertical with supporting plane P.Similarly, the inclination tongue 41 that has extended phalangeal palte 40 has formed the second smooth finger-like board 401 with the second smooth hook portion 421 almost parallels.
According to unshowned other embodiment, cover piece can be formed as more than one parts, and for example housing is provided with the bearing of receiving with breech lock all-in-one-piece bar, or housing is provided with the bearing of receiving pivotal axis (breech lock can carry out pivotable around pivotal axis).In these embodiments, breech lock and housing can be separated by elastic recovery element, and elastic recovery element has the character that trends towards breech lock to remain on the torsionspring in one of its position.
The shape and size of opening 5 and breech lock 4 are chosen as like this: when breech lock 4 is during in its latched position, opening 5 is sealed by phalangeal palte 40 to a great extent.Thereby protect the sensor in the aperture 101 that is contained in support member 100, make it the risk of avoiding the interference of external environment condition and it not almost being damaged.
