Passage 44 can extend along the extension direction being parallel to installation interface 36.Retention member 42 can slide between the first and second positions along extension direction in passage 44.Such as, passage 44 can extend by L along the longitudinal direction, but it should be understood that passage 44 can extend along any direction on demand.Passage 44 can be asymmetric on cross section, only to preset orientation to receive retention member 42 slidably when being assembled in passage 44 when retention member 42 is in relative to connector shell 24.Passage 44 can limit the opening 45 receiving retention member 42.Therefore, retention member 42 can be inserted in passage 44 by opening 45 and therefore insert in connector shell 24, and therefore can shift out opening 45 from connector shell 24 from passage 44.
Such as, outer cover body 32 and therefore connector shell 24 can limit the rear surface 52 contrary with coordinating interface 34.Installation interface 36 is along rear surface 52 and coordinate the direction between interface 34 to extend.Rear surface 52 can limit opening 45.Therefore passage 44 can extend from opening 45 coordinating forward on direction.Therefore, retention member 42 can insert in passage 44 coordinating forward on direction.
Passage 44 extends along a corresponding length, and retention member 42 extends along a corresponding length.The length of passage 44 can be equal to or greater than the length of retention member 42, or alternately can be less than the length of retention member 42.Passage 44 can open at least partially in installation interface 36 and therefore open-minded relative to substrate 30, installation interface 36 can be extended through to make securing member 50 and extend in retention member 42.In other words, at least partially, the such as entire length of passage 44, can extend through installation interface 36 to the length of passage 44.
Outer cover body 32 limits the Part I that the first inner surface 54 and the second inner surface 49, first inner surface limit passage 44, and the second inner surface limits the Part II of passage 44.First inner surface 54 can be upper surface, and the second inner surface 49 can be the lower surface that transversely direction T is contrary with upper surface.Therefore, retention member 42 is grasped between the first inner surface 54 and the second inner surface 49 slidably.First inner surface 54 can limit the first gap 61.First gap 61 can limit the recess extended in outer cover body 32.Second inner surface 49 can limit the second gap 63.Such as, the second gap 63 can be limited by a pair opposition flange 47.Flange 47 can laterally direction A be spaced for opposition.Flange 47 limits the opening that transversely direction T extends through the second inner surface 49.Flange 47 can be limited by outer cover body 32 at installation interface 36 place.And at least one or two in flange 47 can limit the surface that transversely direction T promotes towards the first inner surface 54.
Outer cover body 32 can also limit reciprocal inner surface 55 in a lateral direction a.Inner surface 55 limits a part for passage 44.Inner surface 55 can be positioned such that the first and second gaps 61 and 63 are both disposed fully between inner surface 55 relative to lateral A.And the first gap 61 can extend along the first distance, and the second gap 63 can extend along from first apart from different second distances.Such as, second distance can be greater than the first distance.First and second distances can be measured or can be measured on any suitable replaceability direction on demand in a lateral direction a.
Holding body 43 and therefore retention member 42 can limit the first and second opposition outer surfaces 57 and 59 similarly.First outer surface 57 can be upper surface, and the second outer surface 59 can be the lower surface that transversely direction T is contrary with upper surface.Retention member 42 can also limit the first and second spaced in a lateral direction a outer surfaces 65.Retention member 42 can comprise at least one projection, and at least one projection described extends towards outer cover body 32 from holding body 43 when retention member 42 is disposed in passage 44.First outer surface 57 can limit the first projection 67.Second outer surface 59 can limit the second projection 69.First projection 67 can extend along the first distance.Second projection 69 can extend along from first apart from different second distances.Such as, second distance can be greater than the first distance.First and second distances can be measured or can be measured on any suitable replaceability direction on demand in a lateral direction a.Therefore, retention member 42 only can insert in passage 44 presetting in orientation, and presetting orientation, the first projection 67 is received in the first gap 61, and the second projection 69 is received in the second gap 63.Second projection 69 is too large and can not be received in the first gap 61.Due to the retention member 42 of slim (low profile), retention member 42 can be especially favourable in low profile electrical connector, and described low profile electrical connector comprises the Difference signal pair of low quantity often arranging, such as two.It should be understood that comprise projection 67 with 69 retention member 42 can alternately use together with any electric connector with any amount of Difference signal pair on demand.
At least one or two in retention member 42 and connector shell 24 can limit at least one holding member, and at least one holding member described is configured to limit retention member 42 movement between the first and second positions in passage 44.Holding member can be configured to extruder member, and described extruder member applies extruding force to provide resistance to retention member 42 along the displacement of passage 44 against retention member 42.If the power being applied to retention member 42 along extension direction is less than resistance, then extruding force will prevent retention member 42 from moving between the first and second positions along extension direction.If the power being applied to retention member 42 along extension direction is greater than resistance, then extruding force will be overcome, and retention member 42 moves up along extension direction in the side of the power of applying.
According to the embodiment shown in Fig. 3 A-4E, connector shell 24 can limit at least one holding member 71 projected into from outer cover body 32 passage 44.Such as, at least one holding member described can at least one from the surface partly limiting passage 44 project in passage 44.In one embodiment, the first holding member 71 can from the first inner surface 54 projection.Second holding member 71 also can from the first inner surface 54 projection.First and second holding members 71 can be positioned such that the first gap 61 is disposed between the first and second holding members 71.Alternately or additionally, the first and second holding members 71 from the second inner surface 49 projection, and can be positioned such that the second gap 63 is disposed between the first and second holding members 71.First and second holding members 71 can extend along the extension direction of passage 44.Such as, the first and second holding members 71 can extend by L along the longitudinal direction.
When retention member 42 is disposed in passage 44, the described contact between at least one holding member 71 and retention member of connector shell 24 can towards the opposed surface bias voltage retention member 42 partly limiting passage 44.Therefore, when the first and second holding members 71 are from the first inner surface 54 projection, the first and second holding members 71 can against the second inner surface 49 bias voltage retention member 42, to limit extruding force.Particularly, retention member 42 can the lifting surface of at least one or two described in flange 47 biased.In this respect, promote surface and can limit locator of exerting oneself, extruding force is concentrated on small size by described power locator, increases the power overcome needed for extruding force thus.When the first and second holding members 71 are from the second inner surface 49 projection, the first and second holding members 71 can against the first inner surface 54 bias voltage retention member 42, to limit extruding force.Similarly, when the first and second holding members 71 are from one of them projection inner surface 55, the first and second holding members 71 can against wherein another bias voltage retention member 42 in inner surface 55, to limit extruding force.
In one embodiment, holding member 71 can be configured to conquassation type rib.Therefore, along with retention member 42 inserts in passage 44, retention member causes holding member 71 to lose efficacy under extrusion load, this causes holding member 71 plastic deformation when its holding portion part exerts a force, thus cave in towards the inner surface of connector shell 24, holding member projects into passage from described inner surface.
As mentioned above, retention member 42 comprises at least one aperture 46 at least extended in holding body 43.Retention member 42 can comprise any amount of aperture 46 on demand, such as two or more than two.Therefore, retention member 42 can limit the first and second apertures 46 at least extended in holding body 43.Aperture 46 can be spaced, to make when retention member 42 is in the second place, securing member 50 can pass the respective complementary nibs mouth 48 in substrate 30 and insert in the aligning aperture 46 of retention member 42, further connector shell 24 is fastened to substrate 30.First and second apertures 46 can be spaced along extension direction, and described extension direction can be in the longitudinal directionl according to some embodiment.
The aperture 46 of retention member 42 can be screw-type.In other words, each aperture 46 can be screw-type at least partially.Securing member 50 can be screw-type similarly.Such as, securing member 50 can limit head and the bar portion from head extension.In one embodiment, securing member 50 can be configured to screw, and bar portion is screw-type thus.Therefore, when retention member 42 is in the second place, securing member 50 can upwards be inserted by the complementary type aperture 48 of substrate 30 and insert in the aperture 46 of retention member 42.Particularly, threaded rod can respectively with threaded bores 46 threaded engagement.Along with securing member 50 is screwed in aperture 46 further, extruding force, against substrate supporting, is applied to the substrate 30 between the head of securing member 50 and connector shell 24 by head thus.And securing member 50 can apply to be connected the confining force of the second inner surface 49 bias voltage retention member 42 of device shell 24.Confining force causes the frictional force between retention member 42 and connector shell 24, and described frictional force to prevent when the power consistent with common use is applied to retention member 42 retention member 42 relative to the movement of connector shell 24.Therefore, be applied to being absorbed in the interface of retention member 42 and connector shell 24 at least partially, at most all of the power of connector 22, and the interface between mounting portion 26b and substrate 30 can not be transferred to.It should be understood that the confining force provided by securing member 50 is greater than the extruding force provided by least one holding member described.
It should be understood that the typical electrical connector relative to having fixing retention member, retention member 42 mobility between the first and second positions allows the flexibility in position of the electric connector 22 when electric connector 22 being fastened to substrate 30.Such as, when retention member 42 is in the second place, electric connector 22 can move to the second place along the extension direction of passage 44 from primary importance, aims at at least one aperture 48 described in substrate 30 to make at least one aperture 46 described in retention member 42.Particularly, along with electric connector 22 moves to the second place relative to lower substrate 30 from primary importance, retention member 42 can at passage 44 internal shift, until the corresponding contact position alignment of mounting portion 26b and substrate 30.
