Referring to Fig. 3, main protrusions 121 can form in the central part office of the cross section of containment member 10.When the first connector shell 21 is connected to the second connector shell 22, containment member 10 can be between them compressed and distortion, and main protrusions 121 can flexural deformation.As shown in Figure 4, when the first connector shell 21 is connected to the second connector shell 22, main protrusions 121 can be bent to a side, and crooked main protrusions 121 can be out of shape to be placed in the outer surface S with containment member 10
uin identical plane.When main protrusions 121 flexural deformation, between main protrusions 121 and the first connector shell 21 and the second connector shell 22, can form at least one gap, for example V1 and V2, as shown in Figure 4.Gap V1 and V2 can increase the water resistance of containment member 10, and effectively prevent the inflow of foreign matter.
The gap of containment member 10 in can hermetically sealed connector assembly 20, thus prevent that moisture is on the metal terminal 231 of conduction current and 232 impact.Gap V1 and V2 can produce after containment member 10 distortion.Therefore, the gap between the first connector shell 21 and the second connector shell 22 can be filled with the volume of containment member 10, and can form at least one air layer barrier.Therefore,, even if the foreign matter of scheduled volume flows into, the air layer barrier of gap V1 and V2 also can constrain in foreign matter wherein.
Main protrusions 121 can have compares the relatively large height of its width, makes when the first connector shell 21 is connected to the second connector shell 22, and main protrusions 121 can be flexible.In order to make main protrusions 121 easily crooked, main protrusions 121 can with outer surface S
uform about 90 degree (°) angle.For example, main protrusions 121 can be arranged to vertical and except its top, be the form that is almost similar to rectangle, as shown in the drawing.
Supplementary projection 122 can be formed on the both sides of main protrusions 121.In one embodiment, two supplementary projection 122 can be formed at respectively on the both sides of main protrusions 121.Yet, the invention is not restricted to the example shown in accompanying drawing.In practice, the number of supplementary projection 122 and position can change.Supplementary projection 122 can form based on main protrusions 121 and symmetrical.
Supplementary projection 122 can have the height less than main protrusions 121.When the first connector shell 21 is connected to the second connector shell 22, supplementary projection 122 can be compressed into the outer surface S with containment member 10
uidentical plane.As shown in Figure 4, when the first connector shell 21 is connected to the second connector shell 22, supplementary projection 122 can be compressed between them, makes the ledge of supplementary projection 122 can compressed distortion and flattening.Therefore, supplementary projection 122 can have such height: at this At The Height, supplementary projection 122 can with the outer surface S of containment member 10
ufor same level.Supplementary projection 122 can form has the lower surface wider than main protrusions 121.
Supplementary projection 122 can form slope 122a and the 122b with predetermined angular.Slope 122a and 122b can with the outer surface S of containment member 10
uform relatively shallow angle, make when the first connector shell 21 is connected to the second connector shell 22, supplementary projection 122 can be compressed.Supplementary projection 122 can have the outslope 122b steeper than interior slope 122a.Outslope 122b refers to the gradient towards the outside of containment member 10.Containment member 10 can form to be had than Geng Dou slope, another slope.Steeper slope can be inserted in the direction in connector assembly 20 and form at containment member 10, and another slope can form in the opposite direction.Different from above-mentioned example, two slope 122a and the 122b of supplementary projection 122 can be arranged to symmetric form or unsymmetric form.
Groove or projection can be formed at the interior perimeter surface S of containment member 10
lupper, to increase the connection power with respect to the outer surface of the first connector shell 21.For example, a plurality of grooves 131 and a plurality of convex portions 132 can be formed in the interior perimeter surface part 13 of containment member 10.A plurality of grooves 131 can form and be recessed to desired depth, and a plurality of convex portions 132 can form and projects to predetermined altitude.Groove 131 and convex portions 132 can form along the periphery of the interior perimeter surface of containment member 10.The lower surface of convex portions 132 can form the interior perimeter surface S that covers containment member 10
llargest portion.Be similar to supplementary projection 122, each convex portions 132 can have the slope in the direction of insertion that is formed at containment member 10.
In one embodiment, a plurality of grooves 131 and a plurality of convex portions 132 can be formed in the interior perimeter surface part 13 of containment member 10.Yet, the invention is not restricted to the example shown in accompanying drawing.In practice, various building blocks can be formed in the interior perimeter surface part 13 of containment member 10.
Main protrusions 121 can have than the larger height of supplementary projection 122 and larger cross-sectional area.Supplementary projection 122 can have the lower surface wider than main protrusions 121.Convex portions 132 can have and the similar shape of supplementary projection 122, and can form the interior perimeter surface S that covers containment member 10
llargest portion.The containment member 10 forming as mentioned above can reduce the height of supplementary projection 122 and increase the cumulative volume of containment member 10, makes supplementary projection 122 can be applied in the force compresses distortion on lateral.
Main protrusions 121 and supplementary projection 122 can be out of shape to be placed in the outer surface S with containment member 10
uin identical plane.Therefore, the outer surface S of the containment member 10 of distortion
ucan relatively flatten smooth, and with the interior perimeter surface of the second connector shell 22 close contact equably.As shown in Figure 4, the containment member 10 of distortion can be out of shape relatively equably, and does not compare the significantly part of distortion with other parts.In the figure of Fig. 4, relatively dark part representative is the part of distortion significantly.
Fig. 5 and Fig. 6 show the containment member 30 according to comparing embodiment of the present invention.Fig. 5 is according to the cutaway view of the containment member 30 of this comparing embodiment, and Fig. 6 is the figure that is illustrated in the containment member 30 distortion CAE result afterwards of Fig. 5.Fig. 7 illustrates the figure of the voltage of the conduction current of the vibration based in connector assembly 20 according to an embodiment of the invention.
Referring to Fig. 5, be similar to containment member 10 according to an embodiment of the invention, containment member 30 can comprise ledge 32 and a plurality of convex portions 33.Ledge 32 can comprise single main protrusions 321 and two supplementary projection 322.Convex portions 33 can form along the interior perimeter surface of the main body 31 of containment member 30.Containment member 10 and containment member 30 can be identically formed aspect size and material.Containment member 30 can be different from containment member 10, because supplementary projection 322 can have relatively large height, and the height of supplementary projection 322 can be similar to the height of main protrusions 321.In addition, containment member 30 can be different from the vpg connection of convex portions containment member 10.Referring to Fig. 6, when containment member 30 compressed and when distortion between the first connector shell 21 and the second connector shell 22, main protrusions 321 and supplementary projection 322 all can flexural deformations.
Comparison diagram 4 and Fig. 6, containment member 10 can be deformed into has the outward appearance more smooth than containment member 30.Therefore, containment member 10 can more effectively seal the gap between the first connector shell 21 and the second connector shell 22, and increases waterproof efficiency.
In addition, containment member 30 can have the more significantly crushed element of big figure.In this example, " significantly distortion " shows to change density at corresponding part, and therefore, can change the material character of containment member.
Containment member 10 can occur therein vibration environment in for sealing and water resistance between the first connector shell 21 and the second connector shell 22.Be appreciated that vibration can be absorbed efficiently by containment member 10.Yet, may be difficult to process vibration with containment member 30, because containment member 30 comprises the part that relatively a large amount of wherein material characters changes.
For the fretting corrosion that reduces to be caused by microvibration, may need to reduce the microvibration occurring due to the vibration of the exterior section transmission from connector assembly 20 between terminal.In order to reduce microvibration, can analyze the mobile route of the vibrational energy that is delivered to connector assembly 20.The vibration occurring in vehicle can be transmitted by the bunch (wire harness) that exterior section is connected to connector assembly 20, and the vibrational energy of transmitting can be passed to the first connector shell 21 and the second connector shell 22 or terminal 231 and 232 that contact with each other.The vibrational energy that is delivered to one of the first connector shell 21 and second connector shell 22 can be delivered to another in the first connector shell 21 and the second connector shell 22 by containment member 10.In Fig. 4, use arrow to represent the stream of vibrational energy.Referring to Fig. 4, vibrational energy can be along the first path from bunch or connector pinout (pin) be delivered to for example, in terminal 231 and 232 (, socket or joint) one, and another terminal 231 or 232 that is connected to it.Vibrational energy can be along the second path from bunch or connector pinout be delivered to the first connector shell 21 and the second connector shell 22 one, containment member 10 and another connector shell 21 or 22.
Because fretting corrosion can be caused by the vibration occurring in terminal 231 and 232, maybe advantageously reduce along the amount of the vibrational energy of the first path transmission, to prevent fretting corrosion.In order to reduce, along the amount of the vibrational energy of the first path transmission, may to transmit more substantial vibrational energy along the second path.Conventionally, because the first connector shell 21 and the second connector shell 22 can have relatively large volume, the first connector shell 21 can transmit relative more substantial energy than terminal 231 and 232 with the second connector shell 22.Vibrational energy can be carried out as medium with containment member 10 along the transmission in the second path.Therefore, by containment member 10 being formed and has suitable volume, can obtain the level of density that is enough to transmitting vibrations between the first connector shell 21 and the second connector shell 22.Gap between the first connector shell 21 and the second connector shell 22 can be uniform.Therefore,, in the situation that the volume of containment member 10 increases therein, when connector assembly 20 is coupled, containment member 10 can flexibly be compressed, and the density of containment member 10 can increase.Yet when the volume of containment member 10 excessively increases, the excessive bulk of containment member 10 can affect insertion and the connection of connector assembly 20.
For the efficient transmission of vibrational energy, after containment member 10 distortion, density distribution may need for uniformly.The factor that affects density after containment member 10 distortion can comprise the strain occurring due to the compression after distortion.When there is excessive strain with reservation shape in predetermined portions, the material of corresponding part may extremely be out of shape, and this can bring the radial variations in density.In addition, the radial variations in density can affect the transmission of vibrational energy negatively.
Yet containment member 10 can be out of shape relatively equably, and (for example, the comparing embodiment shown in Fig. 6) part of being significantly out of shape of not comparing other parts.Containment member 10 can be out of shape equably, and has the even variation in density after distortion, thus Transmit evenly vibrational energy.
According to example embodiment, ledge 12 can comprise and forms the main protrusions 121 having than the larger height of supplementary projection 122 and larger volume.When connector assembly 20 is coupled and containment member 10 is out of shape, main protrusions 121 can be on the connection of connector assembly 20 and moving direction flexural deformation and folding gap V1 and V2 can be formed, and supplementary projection 122 can compression to fill the gap in the coupling part of connector assembly 20 with its enough volume.Therefore, the stream of the vibrational energy in containment member 10 can be level and smooth, and can suppress to interfere the strain priming factors of this stream.
Conventionally, the first connector shell 21 and the second connector shell 22 in connector assembly 20 can comprise plastic material, and containment member 10 can comprise can elastic compression material, silicones for example.Plastics and silicones are the materials of the vibrational energy of absorption and decay scheduled volume.Therefore,, when containment member 10 suitably seals gap between the first connector shell 21 and the second connector shell 22 and vibrational energy and transmitted smoothly, vibrational energy can be in the first connector shell 21 and the second connector shell 22 places decay.In addition the containment member 10 relatively large vibrational energy that can decay.
In the situation that the shape of relatively a large amount of parts significantly changes after containment member 10 distortion therein, or relatively a large amount of part has in the situation of larger strain therein, and shock absorption can reduce.In addition, in the situation of silicone material, when distortion state continuance predetermined period time, may there is stress relaxation, and may affect elasticity.Therefore, shock absorption can reduce.According to embodiments of the invention, strain may not can occur significantly, and therefore, shock absorption can be compared with comparing embodiment relatively high.
Can consider temperature about the transmission of vibrational energy in containment member 10 in addition.When connector assembly 20 is exposed to high temperature, each building block can expand with predeterminated level.Although may there are the many variablees based on expansion rate, verified, can prevent fretting corrosion.Can analyze, such expansion can be conducive to the transmission of vibrational energy in connector assembly 20.Along with temperature increases, the shock absorption of plastics and silicone material can increase, and therefore, the microvibration occurring in terminal can reduce.Otherwise when connector assembly 20 is exposed to low temperature, plastics and silicone material are collapsible, make can form gap between the first connector shell 21 and the second connector shell 22.The transmission of vibrational energy can be weakened, and the shock absorption plastics that may cause owing to being declined by temperature and the sclerosis of silicone material reduce.Therefore, energy transmission and extinction efficiency may reduce, and the probability that microvibration occurs in terminal may increase.
In an embodiment of the present invention, by the variation of strain being minimized when increasing volume, vibrational energy can increase by the efficiency of the transmission of containment member 10, and microvibration can be attenuated.Fig. 7 show containment member 10 can be under cryogenic conditions transmitting vibrations energy effectively.Fig. 7 illustrates the figure of the voltage of the conduction current of the vibration based in connector assembly 20 according to an embodiment of the invention.
Referring to Fig. 7, horizontal axis represents to pass in time type and the direction of the vibration that is applied to connector assembly 20, and vertical axis represents the voltage of the electric current that conducted by connector assembly 20.Fig. 7 illustrates the result of measuring the voltage in connector assembly at the temperature of-40 ℃.Connector assembly can comprise the first connector (for example, 91 needle connectors) and the second connector (for example, 105 needle connectors).Referring to Fig. 7, be appreciated that containment member 10 and connector assembly 20 can have the little change in characteristic at low temperatures according to an embodiment of the invention, and connector assembly 20 can have the well tolerable property to vibration.
According to each embodiment, containment member 10 can be with the first connector shell 21 and the second connector shell 22 close contacts to increase sealing property and waterproof efficiency, and effectively prevent that foreign from flowing in connector assembly 20.Containment member 10 can externally have larger vibration attenuation effect in vibration environment by maintaining initial electric restoring force, and effectively absorbs and reduce to be applied to the vibration of connector assembly 20.Contact area and contact force between containment member 10 and the first connector shell 21 and the second connector shell 22 can increase, thereby can effectively reduce the relative motion between the first connector shell 21 and the second connector shell 22, and can prevent the fretting corrosion that caused by microvibration.
A plurality of examples have above been described.Yet, should be appreciated that and can make various modifications.For example,, if if described technology combines by different way and/or replaced or supplemented by other parts or its equivalent with the parts in different order execution and/or described system, framework, device or circuit, can realize suitable result so.Therefore, other embodiment within the scope of the appended claims.
