With reference now to accompanying drawing, cover piece 1 according to the present invention is designed for the aperture 101 closed and be arranged 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 and dull and stereotyped 20 substantially vertical and skirt sections 21 aperture 101 to be accepted 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 defining lug boss 22 thereon on the surface and the receiving space (invisible) below its soffit.This cavity can receive the lug boss being such as arranged on the sensor (not shown) received in space.Receive space to make dull and stereotyped 20 lateral open via the passage 24 opened wide downwards, passage 24 can receive the power cable and/or the communications cable that are such as connected with the electronic entity of motor vehicles by engine speed sensor.Passage 24 is defined by resilient portion 25 in bottom, and cable can be clamped by resilient portion 25 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 relative to aperture 101.Nature it is understood that, 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.First lock-in edge 23 extends on the periphery of whole housing 2, and the supporting plane P (it schematically shows in Fig. 1, Fig. 2 and Fig. 4) of 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: when skirt section 21 is received in aperture 101, this extension is supported on above the edge in aperture 101.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 being provided with breech lock 4 of housing 2.These fastening lugs 3 extend in the mode being roughly parallel to supporting plane P in the plane being different from supporting plane P, to limit the fixed engagement region that the edge in the aperture 101 of support member 100 can be received between fastening lug 3 and the first lock-in edge 23.Therefore, before being turned round at the edge in aperture 101 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.Same it is understood that cover piece can have the breech lock of quantity more than one and/or not have any fastening lug on one or more side.
The edge contrary with the edge with fastening lug 3 of housing 20 and the opening 5 of housing 20 tangent.The pivot axis C transverse seal that opening 5 is formed by the coaxial torque rod 6 that two of extending in breech lock 4 both sides are roughly similar.In this example, opening 5 has rectangular shape.But the edge relative with pivot axis C of opening 5 has two the discontinuous portions limiting clearance portion 50 and fixed stop 51 separately, and 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 the first retainer forming restriction breech lock 4 pivotable.
Breech lock 4 comprises the general planar phalangeal palte 40 of rectangular shape, and phalangeal palte 40 can receive the pressure of user's finger, is made breech lock 4 pivotable to make this phalangeal palte by manual bias voltage towards opening 5.Phalangeal palte 40 can have the groove 49 (it is visible in FIG) of the slip of the lug of restriction bias voltage and strengthening phalangeal palte 40.Therefore, breech lock 4 can between unlocked position and latched position pivotable, breech lock 4 does not hinder cover piece 1 relative to the mobility of support member 100 at unlocked position, and breech lock 4 cooperates to be locked on support member 100 by cover piece 1 in latched position (particularly by means of fastening lug 3 and the first lock-in edge 23) with housing 20.Phalangeal palte 40 is direct and pivot axis C is tangent, and is arranged in the plane almost parallel with pivot axis C.The free edge relative with pivot axis C of phalangeal palte 40 tongue 41 that tilted extends.Phalangeal palte 40 limits first par 400 that can receive user's finger pressure, inclination tongue limits second par 401 that can receive the phalangeal palte of user's finger pressure equally, can find out in the diagram, the first smooth phalangeal palte portion 400 and the second smooth phalangeal palte portion 401 are separated by the second angle beta.Inclination tongue 41 can cooperate to limit breech lock 4 and be pivoted beyond latched position with projection 53.Projection 53 can tilt towards inclination tongue 41 in a complementary fashion.Projection 53 can be strengthened by two flanks 54 projection 53 be connected with housing 20.Therefore, projection 53 and inclination tongue 41 form the complementary shape of restriction first retainer.When they abut, projection 53 and inclination tongue 41 formed relative to supporting plane P tilt abutment plane P'(its schematically show in the diagram).The unlocked position specifically illustrated in figure 3, phalangeal palte 40 extends above housing 20 along with skirt section 21 rightabout.The latched position specifically illustrated in the diagram, phalangeal palte 40 is comprised in the thickness range of housing 20.
Breech lock 4 also comprises the bending hook portion 42 defining the second lock-in edge 7.When breech lock 4 is in the unlocked position, hook portion 42 can not extend outwardly beyond skirt section 21, when breech lock 4 is in latched position, hook portion 42 can make the second lock-in edge 7 extend laterally beyond skirt section 21, with from below by the edge locked in aperture 101 between first lock-in edge 23 and the second lock-in edge 7 of breech lock 4 of housing 20.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 extends in the below of housing 20 in the side identical with skirt section 21.In the example shown, hook portion 42 has the V-arrangement shape of opening wide formed by the first smooth hook portion 420 be connected with pivot axis C by the second smooth hook portion 421.Can find out in the diagram, the first smooth hook portion 420 and the second smooth hook portion 421 are separated by the first angle [alpha].First angle [alpha] is substantially equal to the second angle beta, so that the first smooth hook portion 420 is almost parallel each other and the second smooth hook portion 421 is also almost parallel each other with phalangeal palte portion 401 with phalangeal palte portion 400.
Breech lock 4 also comprise the both sides that are arranged on phalangeal palte 40 and two that extend from pivot axis C in almost parallel each other and roughly vertical with supporting plane P with pivot axis C plane unlock fin 45.According to unshowned embodiment, unlocking fin can tilt relative 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 from pivot axis C and has two the snap close lugs 44 be greater than from pivot axis C to the length of the distance of fixed stop 51 counted from pivot axis C.In addition, snap close lug 44 is set to when breech lock 4 is in during pivotable in the path of the fixed stop 51 formed by opening 5 between its locked.Therefore, the end of snap close lug 44 when not deforming not by fixed stop 51.The end of snap close lug 44 becomes certain inclination angle, to cooperate with the clinoplain 52 of fixed stop 51, thus makes snap close lug 44 lateral deformation, until they are relative with clearance portion 50 and can pass through fixed stop 51.Therefore, by phalangeal palte 40 towards opening 5 manual bias voltage time, realize the motion of the snap close lug 44 between the unlocked position and latched position of breech lock 4 by 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 by fixed stop 51, snap close lug 44 engages with fixed stop 51, turns back to its latched position to prevent breech lock 4.Therefore, snap close lug 44 and fixed stop 51 form the device of snap close breech lock 4 in its latched position.Unlock fin 45 relative to snap close lug 44 with the angled skew of the more remote mode of housing 20 apart.Therefore, when supporting plane P is in level, skirt section 20 is arranged on the below of described supporting plane P, unlocks fin 45 and extends above snap close lug 44.After moving by fixed stop 51, in the latched position of breech lock 4, still can unlock fin 45 from the opposite side of housing 20 (that is, relative with snap close lug 44 above housing 20 side) close to (contact).Therefore, unlock fin 45 and be easy to operation.
Between the end of snap close lug 44 and the end unlocking fin 45, be provided with material remove portion 46 (it illustrates in figs. 3 and 4).Material removes portion 46 can make unblock fin 45 transverse bending, and this will be described in more detail below after a while.In addition, unlock fin 45 to be rigidly fixed on snap close lug 44 and to connect in the mode of elastically deformable relative to pivot axis C.Therefore, the lateral deformation unlocking fin 45 can be caused to the manual bias voltage of transverse direction unlocking fin 45, thus cause the lateral deformation of snap close lug 44, thus finally make the end of each snap close lug 44 relative with corresponding clearance portion 50, and snap close lug 44 can be made by fixed stop 51.Material removes portion 46 can make unblock fin 45 transverse bending, and not with the EDGE CONTACT of inclination tongue 41.Unlocking that fin 45 and clearance portion 50 formed can the tripper of unlocking latch 4, can move to its unlocked position to make breech lock 4 from its latched position.In order to promote the lateral deformation unlocking fin 45 and snap close lug 44, lateral column 43 and phalangeal palte 40 free end at the position of pivot axis C abutting and towards them separates.In addition, each free end unlocking fin 45 is provided with and stretches out edge 47, when unblock fin 45 to press together and pulls breech lock 4 to carry out unlocking latch 4 by user (this will be described below after a while), stretch out the slip of edge 47 limited subscriber finger.
Each lateral column 43 is provided with protuberance 48, and protuberance 48 horizontal expansion on the side contrary with phalangeal palte 40, 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 be 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 defines the second retainer that restriction breech lock 4 is pivoted beyond latched position.
Breech lock 4 and housing 20 are by being arranged to directly aim at the edge of housing 20 and the torque rod 6 limiting pivot axis C is connected to each other.These torque rod 6 elastically deformables, follow breech lock 4 around the pivotable of pivot axis C between its unlocked position and latched position to enable their twisting action.Therefore, cover piece 20 can be fabricated to such as by the molded single moulded parts obtained.Therefore, cover piece 1 is easy to produce.Because this cover piece does not need assembling, because this reducing the loss risk of parts and easy to use.In order to allow the demoulding of cover piece 1, phalangeal palte 40 limits the first smooth phalangeal palte portion 400 almost parallel with the first smooth hook portion 420.Therefore, breech lock 4 can occupy unlocked position, at this unlocked position, the first smooth hook portion 420 and phalangeal palte portion 400 substantially vertical with supporting plane P.Similarly, the inclination tongue 41 extending phalangeal palte 40 defines the second almost parallel smooth phalangeal palte portion 401 of the smooth hook portion 421 with second.
According to other embodiments unshowned, cover piece can be formed as more than one parts, and such as housing is provided with the bearing received with breech lock all-in-one-piece bar, or housing is provided with the bearing 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 trending towards breech lock being remained 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 in its latched position, opening 5 is closed by phalangeal palte 40 to a great extent.Thus protect the sensor be contained in the aperture 101 of support member 100, make it the interference from external environment condition and the risk making it almost not be damaged.
In another embodiment unshowned, snap close lug and unblock fin can be arranged on housing, and make breech lock be provided with clearance portion.In this embodiment, contrary with illustrated embodiment, implement the pivotable of breech lock from unlocked position to latched position by acting directly on breech lock, by act on housing but not breech lock with unblock fin on implement the unblock of breech lock.
