Point.
In order to reduce the fretting corrosion caused by microvibration, it may be necessary to reduce due to from the outside of connector assembly 20
Vibration that part is transmitted and the microvibration that occurs between terminal.In order to reduce microvibration, it can analyze and be transmitted to connector
The mobile route of the vibrational energy of component 20.The vibration occurred in vehicle can be by being connected to connector assembly 20 by exterior section
Bunch (wire harness) transmits, and the vibrational energy transmitted can be passed to the first connector shell 21 being in contact with each other
With the second connector shell 22 or terminal 231 and 232.Be transmitted to the first connector shell 21 and the second connector shell 22 it
One vibrational energy can be transmitted to another in the first connector shell 21 and the second connector shell 22 by containment member 10.
In Fig. 4, make the stream of vibrational energy indicated by an arrow.Referring to Fig. 4, vibrational energy can be along first path from bunch or connector pinout
(pin) one be transmitted in terminal 231 and 232 (for example, socket or connectors), and it is connected to its another terminal 231
Or 232.Vibrational energy can be transmitted to the connection of the first connector shell 21 and second along the second path from bunch or connector pinout
One in device shell 22, containment member 10 and another connector shell 21 or 22.
Since fretting corrosion can be caused by the vibration being happened in terminal 231 and 232, it can be advantageous that reduce along the
The amount for the vibrational energy that one path is transmitted, to prevent fretting corrosion.In order to reduce the amount for the vibrational energy transmitted along first path,
It may need to transmit a greater amount of vibrational energies along the second path.Generally, due to the first connector shell 21 and the second connector
Shell 22 can have relatively large volume, and the first connector shell 21 and the second connector shell 22 can be than 231 Hes of terminal
232 transmit relatively a greater amount of energy.Vibrational energy can be using containment member 10 as medium along the transmission in the second path
It carries out.Therefore, by the way that containment member 10 is formed to have suitable volume, it can obtain and be enough in the first connector shell 21
And second transmit vibration between connector shell 22 level of density.First connector shell 21 and the second connector shell 22 it
Between gap can be uniform.Therefore, wherein in the case of the volume increase of containment member 10, when 20 quilt of connector assembly
When connection, containment member 10 can be elastically compressed, and the density of containment member 10 can increase.However, working as containment member
When 10 volume is excessively increased, the excessive bulk of containment member 10 can influence the insertion and connection of connector assembly 20.
For the efficient transmission of vibrational energy, after the deformation of containment member 10, Density Distribution may need to be uniform.
The factor that density is influenced after the deformation of containment member 10 may include the strain occurred due to deformed compression.When in reservations
When excessive strain occurs with predetermined shape in point, the possible extreme deformation of material of corresponding part, this can bring the radial direction in density
Variation.In addition, the radial variations in density can negatively affect the transmission of vibrational energy.
However, containment member 10 can be deformed relatively evenly, without comparing other parts (for example, shown in Fig. 6
Comparing embodiment) part that substantially deforms.Containment member 10 can equably deform, and have in density after a deformation
Even variation, to Transmit evenly vibrational energy.
According to example embodiment, protrusion 12 may include being formed to have the height and more than 122 bigger of supplementary projection
The main protrusions 121 of big volume.When connector assembly 20 is coupled and containment member 10 deforms, main protrusions 121 can be
Flexural deformation and folding allow gap section V1 and V2 to be formed in the connection of connector assembly 20 and moving direction, and auxiliary
Help protrusion 122 can be with the gap in coupling part of the compressive deformation to fill connector assembly 20 with its enough volume.Therefore,
The stream of vibrational energy in containment member 10 can be smooth, and can inhibit the strain priming factors for interfering the stream.
In general, the first connector shell 21 and the second connector shell 22 in connector assembly 20 may include plasticity material
Material, and containment member 10 may include the material being elastically compressed, such as silicones.Plastics and silicones are to absorb and decay in advance
The material of quantitative vibrational energy.Therefore, when containment member 10 suitably seals outside the first connector shell 21 and the second connector
