DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all drawings of the following embodiments, the same or corresponding parts are designated by the same reference numerals. Furthermore, the present invention is not limited to the embodiments described below.

[0014] (First embodiment) First, a connector connection structure according to a first embodiment of the present invention will be described. Figure 1 shows the connector connection structure according to the first embodiment, and Figure 2 is a cross-sectional view taken along line II-II in Figure 1. In the drawings, various components within the housing are drawn in a transparent state in order to simplify the description of the embodiment and facilitate understanding of the invention.

[0015] The connector connection structure according to the embodiment described below is a connector connection structure having a first connector with at least one connection portion and a second connector that is configured to be able to mate with the first connector and is paired with the first connector, and the structure has a vibration-damping member provided around the connection portion between the first connector and the second connector.

[0016] The connectors 11 and 12 are a pair of connectors for connecting the signal lines 32 to each other. Incidentally, for example, power lines, such as cables routed within a vehicle, may also be connected. The power lines are formed, for example, from a conductor cable that supplies power from a battery within the vehicle to electrical components within the vehicle, and the conductor is formed, for example, from a single wire or a stranded wire made of copper (Cu), a copper alloy (Cu alloy), aluminum (Al), an aluminum alloy (Al alloy), or the like. The single wire or the stranded wire that constitutes the conductor may be tin-plated. Here, the connector 11, which serves as a first connector and is one of the connectors, is, for example, a male connector. The connector 12, which serves as a second connector and is the other connector, is, for example, a female connector. The connector 11 is configured to be matable with the connector 12 so as to be inserted therein.

[0017] The female connector 12 is provided in, for example, an electrical connection box that supplies signals from an ECU (Electronic Control Unit) to electrical components in a vehicle. Note that the connectors 11 and 12 may also be used to connect cables together. For convenience of explanation, in the following description, the x-axis direction shown in the figure is defined as the length direction (the positive side is the front and the opposite side is the rear), the y-axis direction is defined as the width direction, and the z-axis direction is defined as the height direction or up-down direction.

[0018] The connector 11 includes a housing 110. The housing 110 is made of, for example, a synthetic resin, and houses the optical connector 101 having the signal line 32 and the optical connection portion 101a. The housing 110 is made of, for example, a synthetic resin such as polybutylene terephthalate (PBT). Note that the synthetic resin is not limited to PBT, and other synthetic resins may also be used.

[0019] The signal line 32 is a cable that transmits signals between, for example, electrical components in the vehicle and the ECU, and is configured here by, for example, an optical fiber cable, etc. The signal line 32 extends to the outside of the connectors 11 and 12, but is not shown in the figure.

[0020] The optical connector 101 is fixed inside the housing 110. Inside the housing 110, the optical connector 101 is attached to the end of the signal line 32, on the side facing the mating side of the connector 12 in FIG. 1 (the front side in FIG. 1). An optical connection part 101a is provided at the tip side of the optical connector 101 as a connection part. The optical connector 101 is, for example, a so-called MU connector. The optical connector 101 is not limited to an MU connector, and may be a well-known connector such as an LC connector. The optical connector 101 is an example of a connection part for a signal line.

[0021] Furthermore, a vibration-damping member 130 is provided inside the housing 110. The vibration-damping member 130 is provided around the optical connector 101 inside the connector 11 serving as the first connector. Here, it is preferable to fill the inside of the housing 110 with the material constituting the vibration-damping member 130, except for the space provided to enable connection with the optical connector 102. The vibration-damping member 130 provided around the optical connector 101 is a member configured to be able to suppress impacts, particularly spike-like impacts, and suppresses vibrations and impacts within a specific range of frequencies. The vibration-damping member 130 is made of an elastic body or a buffer material. Examples of materials constituting the vibration-damping member 130 include natural rubber, synthetic rubber (including silicone rubber, fluororubber, urethane rubber, etc.), elastomer, fibers such as aramid fiber, and foams or gels of resins (such as polystyrene, polyurethane, and polyolefin).

[0022] The connector 12 includes a housing 120. The housing 120 is made of synthetic resin and houses the optical connector 102, which includes the signal line 32 and the optical connection portion 102a (see FIG. 2). The housing 120 is formed with a connection opening that is open on the side that connects to the connector 11. The connection opening is large enough to allow the tip end of the connector 11 to be inserted. The housing 120 is made of a synthetic resin, such as PBT. Note that the synthetic resin is not limited to PBT, and other synthetic resins may be used.

[0023] As shown in FIG. 2, inside the housing 120, an optical connector 102 is attached to the end of the signal line 32, on the side opposite to the mating side with the connector 11 (rear side in FIG. 1). An optical connection part 102a configured to be connectable to the optical connection part 101a is provided on the connector 11 side of the optical connector 102. Here, it is preferable to fill the part inside the housing 120 other than the space provided to enable connection with the optical connector 101 with the material that constitutes the vibration damping member 130. The optical connector 102 is an example of a connection part for the signal line, and is, for example, an LC connector that can be connected to the optical connector 101. The optical connector 102 is not limited to an LC connector as long as it is connectable to the optical connector 101.

[0024] The space between the housing 120 and the optical connector 102 is filled with a material that constitutes the vibration-damping member 130. In other words, inside the housing 120, the vibration-damping member 130 is provided around the optical connector 102 inside the connector 12, which serves as the second connector. The vibration-damping member 130 provided around the optical connector 102 has a single-layer structure made of the above-mentioned elastic body or cushioning material. This ensures vibration-damping properties in the radial direction (width direction and height direction) of the connector 11.

[0025] The vibration-damping members 130 inside the housings 110 and 120 described above are formed around the optical connectors 101 and 102 as follows: First, the optical connector 101 is fitted into the housing 110. Then, the gap between the optical connector 101 and the housing 110 is filled with the material of the vibration-damping member 130. At the same time, the optical connector 102 is fitted into the housing 120. Then, the gap between the optical connector 102 and the housing 120 is filled with the material of the vibration-damping member 130. In this way, the vibration-damping members 130 are formed around the optical connectors 101 and 102, respectively.

[0026] Furthermore, before fitting the optical connector 101 into the housing 110, a material having predetermined vibration-damping properties may be wrapped around the optical connector 101 in the form of a tape or applied to a predetermined thickness. Furthermore, the housing 110 may be filled with a material having vibration-damping properties in advance, and the optical connector 101 may be pushed in. Similarly, in the housing 120, before fitting the optical connector 102, a material having predetermined vibration-damping properties may be wrapped around the optical connector 102 in the form of a tape or applied to a predetermined thickness, or the housing 120 may be filled with a material having vibration-damping properties in advance, and the optical connector 102 may be pushed in. In either method, the vibration-damping member 130 is formed in a state in which the connectors 11 and 12 can be fitted thereto.

[0027] Furthermore, as shown in FIG. 3 , the connector connection structure 10 according to this embodiment is formed by fitting the connector 11 and the connector 12 together, and the optical connection portion 101a at the tip end of the optical connector 101 and the optical connection portion 102a of the optical connector 102 are connected by fitting the connectors 11 and 12 together. That is, first, the connectors 11 and 12 are brought relatively close to each other, and the tip end of the housing 110 of the connector 11 is fitted into the tip end of the housing 120 of the connector 12. As the connectors 11 and 12 approach each other and are fitted together, the optical connectors 101 and 102 as connecting portions also come into contact with each other and are connected. At the same time, or after this, the housing 110 is fitted into the housing 120 and locked by a predetermined locking mechanism known in the art. In this manner, the fitting of the connectors 11 and 12 is performed.

[0028] As a result, when the optical connectors 101, 102 are connected to each other, the vibration-damping member 130 is provided around the optical connectors 101, 102 that constitute the connection portion of the connectors 11, 12. Here, it is preferable that the vibration-damping member 130 is provided by filling the entire periphery of the connection portion of the optical connectors 101, 102 so as to cover the optical connectors 101, 102 when the optical connectors 101, 102 are mated.

[0029] According to the first embodiment described above, when the connectors 11, 12 are mated, a vibration-damping member 130 made of a predetermined material is provided around the optical connectors 101, 102, thereby making it possible to suppress vibration of the optical connectors 101, 102 within the housings 110, 120 in the longitudinal direction of the connectors 11, 12 and in directions perpendicular to the longitudinal direction (width direction, height direction, radial direction, etc.).

[0030] (Second embodiment) Next, a connector connection structure 10A according to a second embodiment of the present invention will be described. Fig. 4 is a plan view showing the mated state of the optical connector according to the second embodiment, and Fig. 5 is a cross-sectional view taken along line VV in Fig. 4.

[0031] 4, connectors 11A and 12A are a pair of connectors for connecting signal lines 32. Connector 11A, which is one of the connectors and serves as a first connector, and connector 12A, which is the other of the connectors and serves as a second connector, respectively include housings 110A and 120A having approximately the same cross-sectional shape.

[0032] The housing 110A is made of, for example, synthetic resin, like the housing 110, and houses the signal line 32 and the portion of the optical connector 101 on the signal line 32 side. A vibration-damping member 130 is filled in the space between the housing 110A and the signal line 32 and the optical connector 101. As a result, the housing 110A and the optical connector 101 are fixed by the vibration-damping member 130. A connection opening that is open on the connection side with the connector 12A is formed in the housing 110A. At the connection opening on the front side of the optical connector 101, the optical connection portion 101a is exposed from the vibration-damping member 130 filled in the housing 110A. The optical connector 101 is an example of a connection portion for the signal line 32.

[0033] The housing 120A is made of, for example, synthetic resin, like the housing 120, and houses the optical connector 102 having the signal line 32 and the optical connecting portion 102a (see FIG. 5). The housing 120A has a connection opening that is open on the side connecting to the connector 11A. The cross-sectional shape of the connection opening of the housing 120A is substantially the same as the cross-sectional shape of the connection opening of the housing 110A. Inside the housing 120A, the optical connector 102 is provided at the end of the signal line 32, on the side facing the side connecting to the connector 11A in FIG. 4 (the rear side in FIG. 4).

[0034] As shown in FIG. 5, in the connector 12A, an optical connection portion 102a configured to be connectable to the optical connection portion 101a is provided on the connector 11 side of the optical connector 102. The optical connector 102 is an example of a connection portion for a signal line. The space between the housing 120A and the optical connector 102 is filled with a material constituting the vibration-damping member 130. Here, it is preferable to fill the part inside the housing 120A other than the space for enabling connection to the optical connector 101 with the material constituting the vibration-damping member 130. In other words, the vibration-damping member 130 inside the housing 120A is provided around the optical connector 102.

[0035] In this embodiment, the vibration-damping member 130 has a laminated structure made of materials with at least two different vibration-damping characteristics. According to the inventor's knowledge, the frequency band at which vibrations can be absorbed and the change over time of vibration after vibration is applied (e.g., characteristics such as elastic modulus) generally differ depending on the characteristics of the vibration-damping member. Therefore, in order to ensure vibration-damping properties in the radial direction (width direction and height direction) of the connector 12A, it is possible to more effectively improve vibration-damping properties by combining two or more types of vibration-damping members with different vibration-damping properties.

[0036] Furthermore, as with connector 12A, since the frequency band at which vibrations can be absorbed in connector 11A varies depending on the characteristics of the vibration-damping member, combining two or more types of vibration-damping members with different vibration-damping characteristics can more effectively improve vibration-damping performance. Specifically, for example, it is preferable to configure vibration-damping member 130 around optical connector 101 in the same manner as vibration-damping member 130 around optical connector 102. That is, vibration-damping member 130 around optical connector 101 may be configured with a layered structure made of materials 130a, 130b with at least two different vibration-damping characteristics. This ensures vibration-damping performance in the radial direction (width direction and height direction) of connector 11A.

[0037] Furthermore, in the example shown in FIG. 5, the vibration-damping member 130 has a two-layer laminate structure of materials 130a and 130b, but it may also have a three-layer or more laminate structure. Here, it is preferable to have a three-layer or more laminate structure in which vibration-damping members made of three or more materials with different vibration-damping characteristics are laminated. Also, a three-layer or more laminate structure in which adjacent layers have different vibration-damping characteristics and the layers on both sides of a specific layer have the same vibration-damping characteristics may be used. Even in these cases, by using different vibration-damping members, it is possible to more effectively improve vibration-damping properties. Note that the materials 130a and 130b are made of various materials described above in the examples of elastic bodies and cushioning materials.

[0038] The vibration-damping member 130 inside the housings 110A and 120A described above is formed around the optical connectors 101 and 102 as follows. That is, first, material 130b having predetermined vibration-damping properties is wrapped around the optical connectors 101 and 102 in the form of tape or applied to a predetermined thickness. Next, the optical connectors 101 and 102 with material 130b provided thereon are fitted into the housings 110 and 120, respectively. Thereafter, material 130a having vibration-damping properties different from material 130b is filled into the gaps between the optical connectors 101 and 102 and the housings 110 and 120, respectively. In this way, the vibration-damping member 130 having a laminated structure made of materials 130a and 130b having different vibration-damping properties is formed around the optical connectors 101 and 102. Furthermore, before fitting the optical connectors 101 and 102 with the material 130b on their outer peripheries, the housings 110A and 120A may be filled with the material 130a in advance, and the optical connectors 101 and 102 with the material 130b on their outer peripheries may be pushed into the housings 110A and 120A, respectively. In either method, the vibration-damping member 130 is formed in a state that allows the connectors 11 and 12 to be connected to each other.

[0039] In the connector connection structure 10A according to this embodiment, as shown in Fig. 4, the optical connection portion 101a at the tip end of the optical connector 101 and the optical connection portion 102a of the optical connector 102 are connected by adhering the connectors 11A and 12A. That is, first, the connectors 11A and 12A are brought relatively close to each other, and the tip end of the housing 110A of the connector 11A and the tip end of the housing 120A of the connector 12A are adhered to each other. The housings 110A and 120A may be locked with a predetermined locking mechanism to bring them into close contact with each other. The close contact of the connectors 11A and 12A also connects the optical connectors 101 and 102 as connection portions to each other.

[0040] As a result, when the optical connectors 101 and 102 are connected to each other, the vibration-damping member 130 having a laminated structure of the materials 130a and 130b is provided around the optical connectors 101 and 102 that constitute the connection portion of the connectors 11A and 12A. In other words, the vibration-damping member 130 is provided by filling the interior of the housings 110A and 120A so as to cover the optical connectors 101 and 102 when the optical connectors 101 and 102 are connected to each other.

[0041] According to the second embodiment described above, when the connectors 11A, 12A are tightly connected, a vibration-damping member 130 consisting of a laminated structure of materials 130a, 130b having different vibration-damping properties is provided around the optical connectors 101, 102, thereby making it possible to suppress radial impacts and vibrations within the housings 110A, 120A, and therefore achieving the same effects as the first embodiment.

[0042] (Third embodiment) Next, a connector connection structure 10B according to a third embodiment of the present invention will be described. Fig. 6 is a plan view showing the mated state of the connector connection structure 10B according to the fifth embodiment, and Fig. 7 is a cross-sectional view taken along line VII-VII in Fig. 6.

[0043] 6 and 7, a connector connection structure 10B according to this embodiment differs from the second embodiment in that optical connectors 101 and 102 are connected and arranged inside a housing 110B. The optical connectors 101 and 102 and the optical connection portions 101a and 102a are similar to those in the first and second embodiments.

[0044] 6, in a state in which an optical connector 101 serving as a first connector and an optical connector 102 serving as a second connector are connected, a vibration-damping member 130 is provided around the connected portion of the optical connectors 101, 102. In this embodiment, the connected optical connectors 101, 102 form the connection portion of the connector connection structure 10B.

[0045] The housing 110B is made of, for example, synthetic resin, like the housings 110 and 110A. The housing 110B houses the signal line 32 and the optical connectors 101 and 102. A vibration-damping member 130 is filled in the spaces between the housing 110B and the signal line 32 and the optical connectors 101 and 102. This fixes the housing 110B and the optical connectors 101 and 102 together with the vibration-damping member 130. The vibration-damping member 130 has a laminated structure made of materials with at least two different vibration-damping characteristics. The other configurations are the same as those of the second embodiment.

[0046] The vibration-damping member 130 inside the housing 110B described above is formed around the optical connectors 101, 102 as follows. That is, first, the optical connectors 101, 102 are connected. In this case, a housing (not shown) may be further provided for the optical connectors 101, 102. Next, with a predetermined material 130a filled inside the housing 110B, the optical connectors 101, 102 are sandwiched in the width direction. As a result, the optical connectors 101, 102 are housed so as to be immersed in the material 130a inside the housing 110B, and the connector connection structure 10B is formed.

[0047] Here, material 130b having predetermined vibration-damping properties may be wrapped around optical connectors 101, 102 in the form of tape or applied to a predetermined thickness in advance. As a result, in connector connection structure 10B, vibration-damping member 130 having a laminated structure made of materials 130a, 130b having different vibration-damping properties is formed around optical connectors 101, 102, and then housed in housing 110B. Note that material 130a may be filled into gaps in housing 110B from the outside with optical connectors 101, 102, or optical connectors 101, 102 having material 130b having predetermined vibration-damping properties provided on their outer peripheries, inserted into housing 110B.

[0048] As described above, when the optical connectors 101 and 102 are connected to each other, the vibration-damping member 130 having a single layer structure of the material 130a or a laminated structure of the materials 130a and 130b is provided around the optical connectors 101 and 102.

[0049] According to the third embodiment described above, by providing the vibration-damping member 130 around the optical connectors 101 and 102, it becomes possible to suppress impacts and vibrations, particularly in the radial direction, within the housing 110B, thereby achieving the same effects as the first and second embodiments.

[0050] (Fourth embodiment) Next, a connector connection structure 10C according to a fourth embodiment of the present invention will be described. Figures 8 and 9 are a front view and a perspective view, respectively, showing the connector connection structure 10C according to the fourth embodiment.

[0051] As shown in Figures 8 and 9, a connector connection structure 10C according to the fourth embodiment is composed of a first connector, such as a male plug-shaped connector 11C, and a second connector, such as a female outlet-shaped connector 12C.

[0052] The connector 11C has an optical connector 101 as a partial connection portion fitted into a housing 110C that is generally circular in front view and serves as a first housing, with the optical connection portion 101a side being an exposed end. A vibration-damping member 130 is provided around the optical connector 101. The vibration-damping member 130 may be configured by being wrapped around the optical connector 101 in the form of tape or by being applied to a predetermined thickness.

[0053] The housing 110C and the optical connector 101 are configured so that, when rotated in a plane perpendicular to the longitudinal direction of the connector 11C, that is, at least when rotated for fixing after connection, the housing 110C rotates while the optical connector 101 does not rotate, but this is not necessarily limited to this. The connector 11C has a conductive, protruding, convex terminal 111A that is connected to a power line (not shown).

[0054] The connector 12C is provided with an optical connector 102 as a mating connecting portion fitted inside a housing 120C that is generally circular in front view and serves as a second housing, with the optical connecting portion 102a side being the exposed end. The housing 120C and the optical connector 102 are configured so that, when rotating in a plane perpendicular to the longitudinal direction of the connector 12C, that is, at least during rotation for fixing after connection, the housing 120C rotates while the optical connector 102 does not rotate, but this is not necessarily limited to this. The connector 12C is connected to a power line (not shown) and includes a female terminal 112A into which the terminal 111A can be inserted.

[0055] (Connector connection method) The connector connection structure 10C is configured so that after the terminal 111A is fitted into the terminal 112A in the housings 110C and 120C within a plane perpendicular to the longitudinal direction of the connectors 11C and 12A, the housings 110C and 120C can be rotated relative to each other to lock them together. In this case, it is preferable that the optical connectors 101 and 102 maintain their connected state without rotating, but the optical connectors 101 and 102 may also be configured to rotate together. The relative rotation of the housings 110C and 120C applies a connecting force to the terminal 111A of the connector 11C and the terminal 112A of the connector 12C in a direction different from the connecting direction of the optical connectors 101 and 102, in this case the rotational direction. This electrically connects the terminal 111A and the terminal 112A. The other configurations are the same as those of the first to third embodiments, so a description thereof will be omitted.

[0056] In the fourth embodiment, the vibration-damping member 130 is provided around the optical connectors 101 and 102, thereby making it possible to obtain the same effects as in the first to third embodiments.
