Detailed Description

First embodiment

Hereinafter, a connector protection device 10 according to a first embodiment of the present invention will be described with reference to fig. 1A to 6. Fig. 1A and 1B are external perspective views of a connector protection device 10 according to a first embodiment, fig. 1A is an external perspective view of the connector protection device 10 when viewed from a side to be fitted with a connector to be protected, and fig. 1B is an external perspective view of the connector protection device 10 of fig. 1A when viewed from an opposite side.

As shown in fig. 1A and 1B, the connector protection device 10 includes a boot 100 and a retainer 200. In the present first embodiment, the boot 100 is formed of a thermoplastic resin, and the retainer 200 is made of rubber.

Fig. 2A to 2D are views showing the protective cover 100 of the first embodiment, fig. 2A is an external perspective view of the protective cover 100, fig. 2B is a side view of the protective cover 100, fig. 2C is a front view of the protective cover 100 as viewed from the front to the rear in the fitting direction, and fig. 2D is a rear view of the protective cover 100 as viewed from the rear to the front in the fitting direction. Fig. 3A is a cross-sectional view taken along line IIIA-IIIA in fig. 2D, and fig. 3B is a cross-sectional perspective view of the protective cover 100 in a state cut along line IIIA-IIIA in fig. 2D.

As shown in fig. 2A and 2B, the protective cover 100 includes a housing 110. The housing 110 has a fitting portion 120 formed at one end in the fitting direction and having a shape capable of fitting with a connector to be protected (see fig. 6), and a hood portion 130 formed at the opposite end in the fitting direction, the hood portion 130 extending in a direction perpendicular to the fitting direction with the connector to be protected.

In the present embodiment, the direction in which the fitting portion 120 of the protective cover 100 is fitted to the connector to be protected is referred to as the "fitting direction" or the "front-rear direction", and particularly, the side on which the connector to be protected is fitted is referred to as the "fitting direction front side", and the side on which the overhang portion 130 is formed is referred to as the "fitting direction rear side". The forming direction of the brim portion 130 is referred to as "vertical direction", and the direction perpendicular to both the fitting direction and the vertical direction is referred to as "width direction".

The fitting portion 120 is a hollow cylindrical member including a top plate 121, a bottom plate 122, left and right side plates 123, and a rear plate 124 extending in the vertical direction and the width direction, respectively, and the rear portion of the fitting portion 120 is closed by the rear plate 124. The hollow portion is a fitting opening 125 into which a fitting part of the protected connector is inserted.

The eaves 130 protrude vertically from the upper and lower ends of the rear plate 124 of the fitting portion 120 with a thickness in the front-rear direction. An insertion hole 140 penetrating the eaves 130 in the front-rear direction is formed in the upper eaves 130. The insertion hole 140 is elongated in the width direction and has a size into which a connection portion of the retainer 200, which will be described later, can be inserted. A locking projection 150 is formed on the lower brim 130 at a position facing the insertion hole 140. The locking projection 150 is formed with a locking claw 151 protruding downward.

Further, a rib 132 extending from the upper brim 130 forms a connecting portion insertion groove 131. Therefore, the insertion hole 140 is not only conductive in the front-rear direction, but also conductive from the upper side in the front direction of the fitting direction to the lower side in the rear direction of the fitting direction, that is, in the oblique direction. Further, since the lower portion of the connecting portion insertion groove 131 reaches the upper surface of the locking projection 150, the locking projection 150 also has a shape projecting rearward from the rear plate 124 of the fitting portion 120.

Fig. 4 is an external perspective view of the holder 200 of the first embodiment. As shown in fig. 4, the retainer 200 has a first opening 210, a second opening 220, and an elongated connecting portion 230 connecting the first opening 210 and the second opening 22. The first opening 210 is formed in a size and shape that can be locked with the locking projection 150. The second opening 220 is formed in a shape having substantially the same size as or slightly smaller than the outer shape of the fitting portion 120, the brim portion 130, and the connector to be protected of the protective cover 100. In the first embodiment, the connection portion 230 is linear.

Next, the assembly of the connector protection device 10 and the attachment of a connector to be protected in the first embodiment will be described with reference to fig. 5A to 6. Fig. 5A is an elevation view of the first embodiment in a state where the retainer 200 is mounted to the boot 100 in the middle thereof as viewed from the rear in the fitting direction, fig. 5B is a side view of fig. 5A, and fig. 5C is a cross-sectional view taken along the VC-VC line in fig. 5A. Fig. 6 is a diagram showing a usage state of the connector protection device 10 according to the first embodiment when connected to the connector 300 to be protected.

As shown in fig. 5A to 5C, the first opening portion 210 side of the retainer 200 is inserted into the insertion hole 140 formed in the brim portion 130 of the protective cover 100. At this time, as shown in fig. 5B and 5C, the first opening portion 210 side of the connecting portion 230 of the holder 200 is inserted into the insertion hole 140 from the upper side of the front side in the fitting direction toward the lower side of the rear side in the fitting direction, that is, in the oblique direction.

Next, the first opening 210 side of the connecting portion 230 of the retainer 200 is inserted downward along the connecting portion insertion groove 131 between the ribs 132. At this time, since the ribs 132 extend on both sides of the connecting portion 230 in the width direction, the connecting portion 230 can be prevented from largely shifting in the width direction. Next, the first opening portion 210 is locked to the locking claw 151 of the locking projection 150 formed in the lower brim portion 130. In this way, since the first opening portion 210 and the connecting portion 230 of the retainer 200 are inserted into the insertion hole 140 of the boot 100 and further locked to the locking projection 150, even when the connecting portion 230 of the retainer 200 is pulled in the front-rear direction and the width direction on the second opening portion 220 side of the insertion hole 140, the movement of the connecting portion 230 is restricted by the insertion hole 140, and it is difficult to apply a force to the locking portion between the first opening portion 210 and the locking projection 150, and the retainer 200 can be prevented from falling off the boot 100.

Next, as shown in fig. 6, the second opening 220 of the holder 200 is passed around the connector 300 to be protected, and moved around the lead wire 400 connected to the connector 300 to be protected. Next, the fitting portion 120 of the protective cover 100 is fitted to the corresponding fitting portion of the connector 300 to be protected. At this time, the connection portion 230 of the retainer 200 is flexibly bent to be in a bent state. As described above, the protective cover 100 is fitted to the connector 300 to be protected, and thus, when the connector 300 to be protected is not used, it is possible to prevent the intrusion of dust or water.

Further, since the retainer 200 is made of rubber, the lead 400 connected to the connector 300 to be protected is not damaged. Further, since the retainer 200 is made of rubber, when the first opening portion 210 is locked to the locking projection 150 or when it is detached, and when the second opening portion 220 is hooked around the lead wire 400 by passing around the connector 300 to be protected or when it is detached, the size of each can be adjusted by stretching. In other words, if the size of the second opening 220 is substantially the same size or slightly smaller than the outer shape of the protective cover 100 or the outer shape of the connector 300 to be protected, the second opening 220 cannot pass around the connector 300 to be protected unless it is extended slightly larger, and therefore the state in which the retainer 200 and the protective cover 100 are attached to the lead wire 400 can be maintained, and the connector protection device 10 can be prevented from being lost.

When the connector 300 to be protected is connected to another connector and used, and when the connector 300 to be protected is connected to a connector (not shown) connected to an inspection device and used, the fitting portion 120 of the protective cover 100 is separated from the fitting portion of the connector 300 to be protected, and another connector is connected to the fitting portion of the connector 300 to be protected. At this time, since the second opening 220 of the holder 200 is in a state of being caught around the lead wire 400, the protection cover 100 can maintain a state of being attached to the lead wire 400 through the connection portion 230 of the holder 200 and the first opening 210.

In addition, since the insertion hole 140 and the locking projection 150 are formed in the overhang portion 130 extending in the direction perpendicular to the fitting direction in the boot 100 of the first embodiment, it is not necessary to use a slider for moving a part of the mold perpendicular to the mold releasing direction of the mold when molding the boot 100. This can reduce the manufacturing cost and the production cost of the mold.

The retainer 200 can be assembled to the boot 100 by a robot since the retainer 200 is simply inserted into the insertion hole 140 on the side of the first opening 210 and then the first opening 210 is locked to the locking projection 150.

Second embodiment

Next, a connector protection device 10A according to a second embodiment will be described with reference to fig. 7 to 9. The boot 100 of the connector protection device 10A according to the second embodiment is the same as the boot 100 according to the first embodiment, and only the retainer 200B is different in structure, so that detailed description of the structure of the boot 100 is omitted, and the same reference numerals are used for the same components.

Fig. 7 is an external perspective view of the holder 200A of the second embodiment. As shown in fig. 4, the retainer 200A includes a first opening 210A, a second opening 220A, an elongated connecting portion 230 connecting the first opening 210A and the second opening 220A, and a raised portion 240A formed in the connecting portion 230A. As in the first embodiment, the first opening 210A is formed in a size and shape capable of being locked to the locking projection 150 of the boot 100. As in the first embodiment, the second opening 220A is formed in a shape having substantially the same size as or slightly smaller than the outer shape of the fitting portion 120, the brim portion 130, and the connector to be protected of the protective cover 100. In the second embodiment, the connection portion 230A is linear.

The ridge portion 240A is formed at a portion: when the connection portion 230A is inserted into the insertion hole 140 of the boot 100 and the first opening portion 210A is locked by the locking projection 150, the insertion portion of the elongated connection portion 230A inserted into the insertion hole 140 is just on the second opening portion side. In the second embodiment, the ridge portion 240A is formed in such a shape as to be placed on the surface of the connection portion 230A in a direction perpendicular to the extending direction of the connection portion 230A. The ridge portion 240A may have a shape in which the thickness (width) of the connection portion 230A varies.

Next, the assembly of the connector protection device 10A and the attachment of the connector 300 to be protected in the second embodiment will be described with reference to fig. 8A to 9. Fig. 8A is an external perspective view of the second embodiment in a state where the retainer 200A is attached to the protective cover 100, as viewed from the front in the fitting direction, fig. 8B is an external perspective view of the second embodiment in a state where the retainer 200A is attached to the protective cover 100, as viewed from the rear in the fitting direction, and fig. 8C is an elevational view of the second embodiment in a state where the retainer 200A is attached to the protective cover 100, as viewed from the rear in the fitting direction. Fig. 9 is a diagram showing a usage state of the connector protection device 10A according to the second embodiment when connected to the connector 300 to be protected.

As shown in fig. 8A to 8C, the first opening portion 210A side of the retainer 200A is inserted into the insertion hole 140 formed in the brim portion 130 of the protective cover 100, and the first opening portion 210A side of the connecting portion 230A of the retainer 200A is inserted downward along the connecting portion insertion groove 131 between the ribs 132. At this time, since the ribs 132 extend on both sides of the connecting portion 230A in the width direction, the connecting portion 230 can be prevented from largely shifting in the width direction.

Next, the first opening portion 210A is locked to the locking claw 151 of the locking projection 150 formed in the lower overhang portion 130. At this time, the ridge portion 240A formed on the connection portion 230A of the holder 200A is positioned directly above the eaves portion 130 around the insertion hole 140. Thus, even when the connection portion 230A of the retainer 200A is pulled in the front-rear direction and the width direction and further in the vertical direction on the second opening portion 220 side of the insertion hole 140, the movement of the connection portion 230A is restricted by the insertion hole 140 and the contact between the ridge portion 240A of the connection portion 230A and the eaves portion 130, and it is difficult to apply a force to the locking portion of the first opening portion 210A and the locking projection 150, and the retainer 200A can be prevented from falling off the boot 100.

Further, by providing the raised portion 240A, positioning of the retainer 200A when it is assembled to the protective cover 100 becomes easy, and the assembling performance of the automatic assembling machine can be improved.

Next, as shown in fig. 9, the second opening 220A of the holder 200A is passed around the connector 300 to be protected and moved around the lead wire 400 connected to the connector 300 to be protected. Next, the fitting portion 120 of the protective cover 100 is fitted to the corresponding fitting portion of the connector 300 to be protected. At this time, as shown in fig. 9, the connection portion 230 of the retainer 200A is flexibly bent and is in a bent state. As described above, the protective cover 100 is fitted to the connector 300 to be protected, and thus, when the connector 300 to be protected is not used, it is possible to prevent the intrusion of dust or water.

Third embodiment

Next, a connector protection device 10B according to a third embodiment will be described with reference to fig. 10 to 12. The boot 100 of the connector protection device 10B according to the third embodiment is the same as the boot 100 according to the first and second embodiments, and only the structure of the retainer 200B is different from that of the first and second embodiments, so that detailed description of the structure of the boot 100 is omitted, and the same reference numerals are used for the same components.

Fig. 10A is an external perspective view of the retainer 200B according to the third embodiment, fig. 10B is an elevation view of the retainer 200B as viewed from the rear in the fitting direction of the connector protection device 10B, fig. 10C is a plan view of the retainer 200B as viewed from above, and fig. 10D is a side view of the retainer 200B as viewed from the side. As shown in fig. 10A to 10D, the retainer 200B includes a first opening 210B, a second opening 220B, and an elongated connecting portion 230 connecting the first opening 210B and the second opening 220B. As in the first and second embodiments, the first opening 210B is formed in a size and shape that can be locked to the locking projection 150. As in the first embodiment, the second opening 220B is formed in a shape having substantially the same size as or slightly smaller than the outer shape of the fitting portion 120, the brim portion 130, and the connector to be protected of the protective cover 100.

The connecting portion 230B has a bent portion 232B bent 90 degrees in the extending direction. The connection portion 230B forms a first connection portion 234B from the bent portion 232B to the first opening portion 210B side, and forms a second connection portion 236B from the bent portion 232B to the second opening portion 220B side. In the third embodiment, the first connection portion 234B and the second connection portion 236B are located in the same plane. Further, the bent portion 232B is formed at a position: when the connection portion 230B is inserted into the insertion hole 140 of the protective cover 100 and the first opening portion 210B is locked by the locking projection 150, the connection portion 230B is located on the second opening portion 220B side of the insertion portion of the connection portion 230B inserted into the insertion hole 140.

Further, a ridge portion 240B is formed at a portion of the connection portion 230B where the bent portion 232B is formed. In the third embodiment, the ridge portion 240B is formed in a shape protruding in a direction perpendicular to the extension plane of the first connection portion 234B and the second connection portion 236B, that is, in the front-rear direction. As shown in fig. 10B, the ridge portion 240B may extend and protrude in the width direction (left side of the paper in fig. 10B) along the extending direction of the second connection portion 236B beyond the intersection of the first connection portions 234B.

Next, the assembly of the connector protection device 10B and the attachment of the connector 300 to be protected in the third embodiment will be described with reference to fig. 11A to 12. Fig. 11A is an external perspective view of the third embodiment in a state where the retainer 200B is attached to the shield case 100, as viewed from the front in the fitting direction, fig. 11B is an external perspective view of the third embodiment in a state where the retainer 200B is attached to the shield case 100, as viewed from the rear in the fitting direction, fig. 11C is an elevational view of the third embodiment in a state where the retainer 200B is attached to the shield case 100, as viewed from the rear in the fitting direction, and fig. 11D is a plan view of the third embodiment in a state where the retainer 200B is attached to the shield case 100, as viewed from above. Fig. 12 is a diagram showing a usage state of the connector protection device 10B according to the third embodiment when connected to the connector 300 to be protected.

As shown in fig. 11A to 11D, the first opening portion 210B side of the retainer 200B is inserted into the insertion hole 140 formed in the brim portion 130 of the protective cover 100, and the first connection portion 234B of the retainer 200B is inserted downward along the connection portion insertion groove 131 between the ribs 132. At this time, since the ribs 132 extend on both sides of the first connecting portion 234B in the width direction, the first connecting portion 234B can be prevented from largely shifting in the width direction.

Next, the first opening portion 210B is locked to the locking claw 151 of the locking projection 150 formed in the lower brim portion 130. At this time, the bulging portion 240B formed at the bent portion 232B of the holder 200B is located directly above the eaves portion 130 around the insertion hole 140. Thus, even when the second connecting portion 236B of the retainer 200B is pulled in the front-rear direction and the width direction, and further in the vertical direction, the movement of the first connecting portion 234B is restricted by the contact between the insertion hole 140 and the ridge portion 240B with the eaves portion 130, and it is difficult to apply a force to the locking portion of the first opening portion 210B and the locking projection 150, and the retainer 200B can be prevented from falling off the boot 100.

Next, as shown in fig. 12, the second opening 220B of the holder 200B is moved to the periphery of the lead wire 400 connected to the connector 300 to be protected by passing around the connector 300 to be protected. Next, the fitting portion 120 of the protective cover 100 is fitted to the corresponding fitting portion of the connector 300 to be protected. At this time, as shown in fig. 12, the second connecting portion 236B of the retainer 200B is flexibly flexed to be in a bent state. As described above, the protective cover 100 is fitted to the connector 300 to be protected, and thus, when the connector 300 to be protected is not used, it is possible to prevent the intrusion of dust or water.

As shown in fig. 12, when the first connection portion 234B is inserted into the connection portion insertion groove 131 of the shield 100, the second connection portion 236B extends in the width direction of the shield 100 by the bent portion 232B of the holder 200B. In this state, when the second opening 220B is attached to the connector 300 or the lead 400 to be protected, the second connection portion 236B is bent to avoid the top plate 121 of the protective cover 100 and the upper surface of the connector 300 to be protected. Since a mechanism for releasing the connector lock is often provided on the upper surface of the connector 300 to be protected, the second connecting portion 236B does not interfere with the operation of releasing the connector lock if it is configured as described above.

Fig. 13 is a diagram showing a state in which the male connector 500 is fitted to the connector 300 to be protected. As shown in fig. 13, a male connector 500 is fitted and connected to the connector 300 to be protected, and an electric current can be supplied. At this time, although the protective cover 100 of the connector protection device 10B is detached from the connector 300 to be protected, the second opening 220B of the retainer 200B connected to the protective cover 100 is held in a state of being hung on the lead wire 400, and the protective cover 100 is suspended from the lead wire 400 by the retainer 200B. This can prevent the loss of the protective cover 100.

In the third embodiment, the example in which the retainer 200B is bent 90 degrees at the bent portion 232B has been described, but the present invention is not limited to this, and the retainer may be bent at a different angle at the position of the bent portion 232B, and may have a plurality of bent portions in addition to the bent portion 232B.

The protrusions 240A and 240B of the second and third embodiments may have any shape as long as they are larger than the size of the insertion hole 140. Alternatively, any configuration may be adopted as long as it prevents the second opening 220A side of the connection portion 230A from being inserted into the insertion hole 140 with respect to the ridge portion 240A or the second connection portion 236B.

The connector protection devices according to the first to third embodiments have been described above. The above-described embodiments describe an example of the connector protection device of the present invention, and the present invention is not limited to the above-described connector protection device, and should be applied to other connector protection devices as set forth in the claims.

For example, in the first to third embodiments, the insertion hole 140 and the locking projection 150 are formed in the eaves 130 of the housing 110 of the boot 100 that protrudes upward and downward. However, the insertion hole 140 and the locking projection 150 may be formed at the end in the width direction. The insertion hole 140 or the locking projection 150 may not be formed at the end of the housing 110 in the vertical direction or the width direction. For example, the insertion hole 140 may be formed at one end in the vertical direction or one end in the width direction of the housing 110, and the locking projection 150 may be formed at the center of the rear plate 124 of the housing 110. Alternatively, the locking projection 150 may be formed at one end in the vertical direction or one end in the width direction of the housing 110, and the insertion hole 140 may be formed at the center of the rear plate 124 of the housing 110.

In the first to third embodiments, the case where the insertion hole 140 and the locking projection 150 are formed individually has been described, but the present invention is not limited to the above example, and two or more insertion holes 140 and two or more locking projections 150 may be formed. However, in this case, the first openings 210 corresponding to the number of the insertion holes 140 and the locking projections 150 need to be formed in the retainers 200, 200A, and 200B.
