Description

  The present invention relates to a connector that engages with a mating connector by rotating a lever.

  Examples of this type of connector include those disclosed in Patent Literature 1 and Patent Literature 2. The levers of the connectors of Patent Literature 1 and Patent Literature 2 are accommodated in the lever accommodating portion of the housing so as to be rotatable between the first position and the second position. In any connector, when the lever is in the first position or a position close to the first position, the mating connector can be temporarily fitted to the connector. If it is rotated, the temporary fitting cannot be performed. The limit position where the temporary fitting is possible is defined as the third position. That is, the third position is between the first position and the second position. Further, when the lever is between the first position and the third position, the mating connector can be temporarily fitted to the connector. After temporarily fitting the mating connector to the connector, the mating connector and the connector can be fitted (main fitting) by turning the lever toward the second position.

  The connectors of Patent Document 1 and Patent Document 2 are provided with a temporary fixing elastic portion as means for regulating the position of the lever in order to ensure the temporary fitting between the connector and the mating connector. The temporary fixing elastic part is configured to be able to temporarily receive (temporarily fix) the lever at the third position when the lever in the vicinity of the first position is rotated toward the second position. ing. Thereby, the temporary fixing elastic part can temporarily stop the lever from moving beyond the third position toward the second position. The temporary fixing of the lever by the temporary fixing elastic portion is released when the temporary fixing elastic portion is detached from the lever by the elastic deformation of the temporary fixing elastic portion by the mating connector when temporarily fitting the mating connector to the connector.

  As shown in FIG. 1, the connector assembly 10 according to the embodiment of the present invention includes a male connector (mating connector) 100 and a female connector (connector) 200.

  As shown in FIG. 2, the male connector 100 includes a plurality of metal male contacts 105 and a male housing 110 made of an insulator that holds the male contacts 105. The male housing 110 has a male fitting portion 112 having a rectangular tube shape with a rectangular cross section, and a guided portion 120 is provided on the upper surface of the male fitting portion 112. A rack portion 130 is formed on the portion 120. The guided portion 120 has a plate-like outer shape that protrudes in the + Z direction (upward) from the male fitting portion 112 and extends along the X direction (front-rear direction). The rack portion 130 has an island shape and further protrudes from the guided portion 120 in the + Z direction. The rack portion 130 is provided with a rack groove 132 that is recessed in the + Y direction.

  As shown in FIGS. 3 to 6, the female connector 200 includes a female housing (housing) 210 made of an insulator, a lever 270 made of an insulator, and a rear cover 300. The female connector 200 is a so-called waterproof connector, and further includes a female contact and a seal member connected to the male contact 105. However, in order to clarify the point of the invention, the female contact and the seal member are not shown. The explanation is also omitted.

  As shown in FIGS. 7 to 10, the female housing 210 is formed with a lever accommodating portion 220 that communicates a front end 212 and a rear end 214 that function as a female fitting portion. The lever accommodating portion 220 includes an upper portion (top plate) 222, a lower portion 224, and side portions 226 and 228 that connect the upper portion 222 and the lower portion 224 at both ends in the Y direction (width direction). In particular, as shown in FIGS. 9 and 10, the lower portion 224 of the lever accommodating portion 220 has a width corresponding to the width of the guided portion 120 (the size in the Y direction) and from the front end 212 to the −X direction ( A guide portion 230 extending rearward is formed. The guide part 230 has penetrated the lower part 224 in the Z direction (up-down direction). As shown in FIGS. 23 and 24, when the male connector 100 and the female connector 200 are fitted, the guide portion 230 guides the guided portion 120 so as not to move in the Y direction. By the guide of the guided portion 120 by the guide portion 230, the rack portion 130 can also move only in the X direction (front-rear direction) without moving in the Y direction (width direction) when mated and removed.

  As shown in FIGS. 8 and 10, a rotation shaft 240, a temporary fixing elastic portion 250, and a connection portion 260 are formed in the lever housing portion 220. The rotating shaft 240 has a short columnar shape, and protrudes from the lower portion 224 of the lever accommodating portion 220 in the + Z direction (upward). The temporary fixing elastic part 250 is elastically deformed in the XY plane. As best shown in FIG. 12, it has a rod-like shape extending in the X direction. The temporary fixing elastic portion 250 includes a receiving portion 252 having a surface intersecting the X direction, a release portion 254 located on the + X side (front) of the receiving portion 252, and a rear end portion 256. As understood from FIGS. 12 and 13, the release portion 254 projects in the −Y direction so as to overlap the guide portion 230 in the Z direction. As can be understood from FIGS. 11 to 13, since the temporary fixing elastic portion 250 according to the present embodiment is separated from the upper portion 222 and the lower portion 224 of the lever accommodating portion 220, the length (spring) can be elastically deformed. Long) can be taken longer. The connecting portion 260 is provided at the intersection of the side portion 226 and the rear end 214, that is, at one of the corners of the lever accommodating portion 220, and the side of the temporary end elastic portion 250 at the side of the rear end portion 256 and the side portion 226. Is connected. As shown in FIG. 11, the connection part 260 is separated from the upper part 222 of the lever accommodating part 220. In other words, the female housing 210 is formed with a slit 262 reaching the side portion 226 so as to separate the connection portion 260 and the upper portion 222 when viewed from behind (when viewed along the + X direction). ing. Thus, in the present embodiment, since the temporary fixing elastic portion 250 and the connection portion 260 are separated from the upper portion 222, the upper portion 222 is soft and easily elastically deformed. A stepped connected portion 216 is formed in the −Y direction of the connecting portion 260.

  Referring to FIGS. 14 and 15, the lever 270 has a substantially quadrangular plate-like outer shape, and can rotate the operating portion 272 for rotating the rotating shaft 240 and the rotating shaft 240. A bearing portion 274 to be supported and a guide groove 276 continuous with the bearing portion 274 are provided. The operation part 272 is formed at one of the corners on the rear end 270b side of the substantially square shape. As understood from FIGS. 14 and 15, the bearing portion 274 and the guide groove 276 are provided on the lower surface 270 l side of the lever 270 and are not visible from the upper surface 270 u side. The bearing portion 274 is formed on the front end 270 f side of the center of gravity of the lever 270 in order to increase the distance from the operation portion 272. The guide groove 276 is formed between the front end 270 f of the lever 270 and the bearing portion 274. The guide groove 276 is a shallow groove compared to the bearing portion 274, but an excessive load is applied to the upper portion 222 when the lever 270 is incorporated into the lever accommodating portion 220 as compared with the case where the guide groove 276 is not provided. Can be avoided. When the lever 270 is incorporated into the lever housing 220 using the guide groove 276, the lever 270 is press-fitted into the lever housing 220 from the rear end 214 of the female housing 210. In the state after the assembly, as shown in FIGS. 21 and 22, the operation portion 272 of the lever 270 is located closest to the rear end 214 of the female housing 210. The position of the lever 270 at this time is referred to as a second position.

  As shown in FIGS. 14 and 15, a first contact portion 278 is formed in the vicinity of the operation portion 272 on the rear end 270 b side of the lever 270. As shown in FIGS. 14, 15, and 19, the first contact portion 278 has a shape in which a lower end 278 l protrudes in a horizontal plane from an upper end 278 u. Specifically, the first contact portion 278 is a slope extending obliquely from the upper end 278u to the lower end 278l.

  Near the other corner of the rear end 270b of the lever 270, a receiving portion 280 that is temporarily fixed to the receiving portion 252 of the temporary fixing elastic portion 250 is formed. The first contact portion 278 is located between the received portion 280 and the operation portion 272. As can be understood from FIG. 20, when the receiving portion 280 is positioned in front of the receiving portion 252 (+ X side) of the temporary fixing elastic portion 250, the lever 270 is rotated toward the second position. Even if it tries to make it, the to-be-received part 280 contacts the receiving part 252. The position of the lever 270 when the received portion 280 comes into contact with the receiving portion 252 is defined as a third position. In other words, the lever 270 may rotate the lever 270 toward the second position when the received portion 280 is positioned in front of the receiving portion 252 of the temporary fixing elastic portion 250 (+ X side). It cannot move beyond the third position to the second position side.

  As shown in FIGS. 15, 20, and 22, a pinion protrusion 290 is formed in front of the receiving portion 280. The pinion protrusion 290 protrudes in the radial direction around the bearing portion 274. As can be understood from FIGS. 20 and 22, the pinion protrusion 290 protrudes on the guide portion 230. That is, as can be understood from FIGS. 23 and 24, the pinion protrusion 290 protrudes on the movement path of the rack portion 130 when the male connector 100 and the female connector 200 are fitted.

  As shown in FIG. 16, a mounting member 400 is integrally formed with the rear cover 300. That is, the attachment member 400 according to the present embodiment is formed as a part of the rear cover 300 and is separate from the female housing 210. The mounting member 400 may be a separate body from the rear cover 300 as long as it is a separate body from the female housing 210.

  As shown in FIGS. 16 and 17, the attachment member 400 includes an attachment main portion 410 having an L shape. The attachment main portion 410 has a vertical portion 412 extending in the + Z direction (upward direction) and a horizontal portion 414 extending in the −Y direction (width direction). At the + Z side end (upper end) of the vertical portion 412, a connecting portion 420 that protrudes in both the Y directions is formed. The connecting portion 420 is fitted into the connected portion 216 of the female housing 210, whereby the attachment member 400 connects the upper portion 222 and the lower portion 224 of the lever accommodating portion 220. Thus, after attaching the attachment member 400 to the rear end 214 of the female housing 210, the lever accommodating part 220 is reinforced by the attachment member 400, and the deformation | transformation of the upper part 222 is suppressed. Therefore, it can be avoided that the upper portion 222 is elastically deformed and the lever 270 is detached. On the other hand, when the lever 270 is incorporated into the lever accommodating portion 220, the upper portion 222 is easily elastically deformed, so that the upper portion 222 and the lever 270 can be prevented from being damaged. In order to suppress deformation of the upper portion 222, it is desirable to connect the upper portion 222 and the lower portion 224 at a position close to the center in the width direction (Y direction) as long as a predetermined rotation range of the lever 270 is secured. Further, the width (size in the Y direction) of the vertical portion 412 of the mounting main portion 410 should be as thick as possible.

  As shown in FIGS. 16 and 17, a second contact portion 430 that contacts the first contact portion 278 is formed at the end of the lateral portion 414. The distance from the second contact portion 430 to the rotation center of the lever 270 (that is, the bearing portion 274) is longer than the distance from the front end 270f of the lever 270 to the rotation center. As understood from FIGS. 17 and 19, the second contact portion 430 has a shape in which the upper end 430 u protrudes in the horizontal plane from the lower end 430 l. Specifically, the second contact portion 430 is a slope extending obliquely from the lower end 430l to the upper end 430u. As can be understood from FIG. 19, the inclined surface of the second contact portion 430 is designed to be in surface contact with the inclined surface of the first contact portion 278. When the lever 270 is rotated in the direction away from the second position, the first contact portion 278 and the second contact portion 430 come into contact with each other. The position of the lever 270 at this time is referred to as a first position. That is, the lever 270 cannot be rotated in the direction away from the second position beyond the first position because the first contact portion 278 and the second contact portion 430 are in contact. When the first contact portion 278 and the second contact portion 430 are in contact with each other, it is possible to prevent the lever 270 from being lifted in the direction in which the lever 270 is detached from the rotation shaft 240 (the direction in which the upper portion 222 of the lever housing portion 220 is opened). . In particular, in the present embodiment, as described above, since the distance from the lever 270 to the second contact portion 430 can be increased, the rotation restriction is restricted compared to the connector of Patent Document 1. It can be done reliably.

  The first position is one of the rotation limits of the lever 270. The other rotation limit is the second position as described above. That is, the lever 270 according to the present embodiment is accommodated in the lever accommodating portion 220 so as to be rotatable between the first position and the second position.

  As can be understood from FIGS. 18 and 20, when the receiving portion 280 is located in front of the receiving portion 252 (+ X side) of the temporary fixing elastic portion 250, the lever 270 is in the first position and the third position. It is located between the positions (including the first position and the third position). At this time, if the lever 270 is rotated toward the second position, the receiving portion 280 of the lever 270 is received by the receiving portion 252 of the temporary fixing elastic portion 250 as described above. The rotation exceeding is suppressed. At this time, in the present embodiment, the attachment member 400 is adjacent to the connection portion 260 in the Y direction (width direction), and the backup portion 440 formed from the front surface of the vertical portion 412 of the attachment main portion 410 is temporarily fixed elastic portion. Since the back-up portion 256 is backed up by receiving the rear end portion 256 from the rear, the rigidity of the temporary fixing elastic portion 250 is enhanced. Therefore, it is possible to suppress the problem that the temporary fixing of the lever 270 due to the contact between the receiving portion 252 and the received portion 280 is unintentionally released. In particular, since the backup portion 440 according to the present embodiment is larger than the rear end portion 256 of the temporary fixing elastic portion 250 in the Y direction (width direction), the temporary fixing elastic portion 250 can be reliably backed up. In the present embodiment, as shown in FIG. 23, the backup portion 440 is provided so as to contact the rear end portion 256 of the temporary fixing elastic portion 250, but the present invention is not limited to this. . For example, as long as the backup portion 440 is in contact with the rear end portion 256 of the temporary fixing elastic portion 250 when the receiving portion 252 of the temporary fixing elastic portion 250 receives the received portion 280 of the lever 270, the temporary fixing elastic portion 250 When the receiving part 252 of the part 250 does not receive the receiving part 280 of the lever 270, the backup part 440 may be slightly separated from the rear end part 256 of the temporary fixing elastic part 250.

  On the other hand, when the temporary fixing elastic portion 250 is elastically deformed so that the receiving portion 252 and the releasing portion 254 move to the + Y side (side portion 226 side), there is nothing that inhibits the elastic deformation. Therefore, the state in which the lever 270 is incorporated in the female housing 210 (FIGS. 21 and 22) is shifted to a state (FIGS. 18 and 20) in which the receiving portion 280 is positioned in front of the receiving portion 252 (+ X side). At this time, the temporary fixing elastic portion 250 can be softly deformed.

  As can be understood from FIGS. 18, 20, and 23, when the lever 270 is located between the first position and the third position (including the first position and the third position), The pinion protrusion 290 can be engaged with the rack groove 132. That is, as shown in FIG. 24, the male connector 100 and the female connector 200 can be temporarily fitted. When the male connector 100 and the female connector 200 are temporarily fitted, the release portion 254 of the temporary fixing elastic portion 250 is pressed to the + Y side (side portion 226 side) by the rack portion 130, and the temporary fixing elastic portion 250 is elastic. The receiving part 252 is also deformed and moves to the + Y side (side part 226 side). Thereby, the position of the receiving part 252 and the to-be-received part 280 shifts | deviates in a Y direction (width direction), and the lever 270 can be rotated in the direction approaching a 2nd position. When the pinion protrusion 290 is engaged with the rack groove 132 and the operating portion 272 of the lever 270 is pressed in the direction approaching the rear end 214 of the female housing 210, the fitting between the male connector 100 and the female connector 200 proceeds. When the lever 270 moves to the second position, the fitting between the male connector 100 and the female connector 200 is completed (mainly fitted state).

  In addition, since the length (spring length) of the temporary fixing elastic portion can be increased, soft elastic deformation of the temporary fixing elastic portion can be secured, and when the lever is temporarily fixed by the temporary fixing elastic portion. These two effects that the temporarily fixed elastic portion is reinforced are easily realized because the mounting member is separated from the housing. According to a general molding process, in order to form the temporary fixing elastic part integrally with the housing while separating the upper part (top plate) and the lower part of the lever housing part, at least some space behind the temporary fixing elastic part. Is required. On the other hand, a backup of the temporarily fixed elastic part for temporarily fixing the lever is impossible if a space required at the time of the molding process exists behind the temporarily fixed elastic part. In the present invention, in the step of molding the temporary fixing elastic part, while allowing the space required at the time of the molding process to exist behind the temporary fixing elastic part, it is separated from the housing later. Since the attachment member is attached to the rear end of the housing so as to be positioned behind the rear end portion of the temporary fixing elastic portion, the two effects described above can be obtained.

  Although the present invention has been specifically described with reference to the embodiment, the present invention is not limited to this. In the embodiment described above, a portion protruding from the rear cover 300 to the + X side (forward) is not formed, but a portion protruding to the X side (forward) from the mounting member 400 may be formed. For example, a portion protruding to the + X side (front) is provided on the attachment member 400 so as to contact the side portion 228 side of the rear end portion 256 of the temporary fixing elastic portion 250, and this portion is also a part of the backup portion 440. good. In this case, the backup portion has an L-shaped cross section in the XY plane.

  The present invention is applicable to a waterproof connector as in the embodiment described above. Moreover, if it is a type which has a lever, it is applicable also to connectors other than a waterproof connector.
