[0004] Patent Document 1: Japanese Patent Application Laid-Open No. 2009-266383 Summary of the Invention Problems to be Solved by the Invention

[0005] In the above-described rod-type connector, since the first restraining portion and the second restraining portion for restraining misrotation are provided at different positions on the wire cover, the wire cover is enlarged, which is not conducive to the space-saving of the entire rod-type connector. Solutions to the Problems

[0006] The rod-type connector of the present disclosure is a rod-type connector that can be engaged with a mating connector on the other side, and includes: a housing; a rod rotatably mounted on the housing; and a cover mounted on the back side of the housing. The rod can rotate between an engagement start position and an engagement end position, and when moving from the engagement start position to the engagement end position, it engages with the mating connector on the other side, and when moving from the engagement end position to the engagement start position, it disengages from the mating connector on the other side. The cover includes a first receiving portion and a second receiving portion. Among them, the first receiving portion restrains the rod located at the engagement start position from rotating by mistake to the side opposite to the engagement end position, and the second receiving portion restrains the rod located at the engagement end position from rotating by mistake to the side opposite to the engagement start position. The first receiving portion and the second receiving portion are formed by a single rib. Advantages of the Invention

[0007] According to the present disclosure, by preventing the rod from rotating accidentally with a single rib, it is possible to achieve space saving of the rod-type connector. Description of the Drawings

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described. (1) The rod-type connector of the present disclosure is a rod-type connector that can be fitted with a mating connector, and includes: a housing; a rod rotatably mounted on the housing; and a cover mounted on the back side of the housing. The rod can rotate between a fitting start position and a fitting end position. When moving from the fitting start position to the fitting end position, it fits toward the mating connector. When moving from the fitting end position to the fitting start position, it disengages from the mating connector. The cover has a first receiving portion and a second receiving portion. Among them, the first receiving portion inhibits the rod located at the fitting start position from accidentally rotating in a direction opposite to the fitting end position, and the second receiving portion inhibits the rod located at the fitting end position from accidentally rotating in a direction opposite to the fitting start position. The first receiving portion and the second receiving portion are formed by a single rib.

[0010] In the above rod-type connector, the rod fits toward the mating connector by moving from the fitting start position to the fitting end position, and disengages from the mating connector by moving the rod from the fitting end position to the fitting start position. Here, when the rod at the fitting start position tends to accidentally rotate in a direction opposite to the fitting end position, the accidental rotation is inhibited by the first receiving portion. In addition, when the rod at the fitting end position tends to accidentally rotate in a direction opposite to the fitting start position, the accidental rotation is inhibited by the second receiving portion.

[0011] Here, since the first receiving portion and the second receiving portion are formed by a single rib, compared with the case where the first receiving portion and the second receiving portion are respectively provided at different positions on the cover, the cover can be made more space-saving, and the rod-type connector as a whole can also be made more space-saving. Therefore, by using a single rib to prevent the accidental rotation of the rod, the space-saving of the rod-type connector can be achieved.

[0012] (2) Preferably, the housing has a shaft portion that rotatably supports the rod. The rod has a first abutting portion that abuts against the first receiving portion at the fitting start position and a second abutting portion that abuts against the second receiving portion at the fitting end position. In a direction intersecting with the fitting direction of the rod-type connector and the mating connector, the first abutting portion is disposed on one side of the shaft portion, and the second abutting portion is disposed on the other side of the shaft portion. Since the first abutting portion is disposed on one side of the shaft portion and the second abutting portion is disposed on the other side of the shaft portion, when the first abutting portion moves in a direction away from the first receiving portion of the rib, the second abutting portion moves in a direction approaching the second receiving portion of the rib. On the contrary, when the second abutting portion moves in a direction away from the second receiving portion of the rib, the first abutting portion moves in a direction approaching the first receiving portion of the rib. Therefore, the accidental rotation of the rod can be inhibited by a single rib.

[0013] (3) Preferably, the cover has a lead-out port for leading out the electric wire led out from the back surface of the housing to a direction different from its lead-out direction, and the rib is provided on the wall portion of the cover located on the side opposite to the lead-out port. When providing a lead-out port in the cover, it can be assumed that the strength of the peripheral portion of the lead-out port is reduced. In this regard, since the rib is provided on the wall portion of the cover located on the side opposite to the lead-out port, it is difficult to be affected by the strength reduction, and the erroneous rotation of the lever can be reliably suppressed.

[0014] [Details of the embodiments of the present disclosure] The following describes specific examples of the lever-type connector of the present disclosure with reference to the drawings. Further, the present disclosure is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the equivalent meaning and scope of the claims.

[0015] <Embodiment 1> While referring to Figures 1 to 11 While describing Embodiment 1. The mating connector 50 with which the lever-type connector 10 can be fitted is a board connector mounted on a circuit board (not shown). In the present embodiment, a plurality of lever-type connectors 10 can be fitted to one mating connector 50. For example, Figure 1 The case where three lever-type connectors 10 can be fitted to the mating connector 50 is illustrated.

[0016] [Mating connector] As Figure 9 shown, the mating connector 50 includes a mating housing 51 and a plurality of mating terminals 52 held by the mating housing 51. The mating housing 51 is made of synthetic resin and is generally horizontally long and rectangular. The mating housing 51 has a plurality of fitting recesses 53 into which the lever-type connector 10 can be fitted.

[0017] A pair of cam pins 54 are provided on both side walls 53A on the left and right sides constituting the fitting recess 53. The pair of cam pins 54 respectively project from each side wall 53A and are arranged symmetrically left and right. The cam pin 54 is formed in a cylindrical shape.

[0018] The mating terminal 52 is constituted by a needle-shaped terminal made of metal and is held by the inner wall 53B of the fitting recess 53 in a state of penetrating the inner wall 53B in the front-rear direction. One end of the mating terminal 52 projects forward from the inner wall 53B, and the other end of the mating terminal 52 projects rearward from the inner wall 53B and then bends downward. The other end of the mating terminal 52 is inserted into a through hole of the circuit board and fixed to the circuit board, and is a press-fit terminal.

[0019] [Lever-type connector] As Figure 8 shown, the lever-type connector 10 includes a housing 20, a cover 30, and a lever 40. The lever 40 can beFigure 8 The chimera start position shown is Figure 7 When the lever 40 moves from the mating start position to the mating end position, the lever-type connector 10 is mated toward the mating connector 50, and conversely, when the lever 40 moves from the mating end position to the mating start position, the lever-type connector 10 is disengaged from the mating connector 50.

[0020] like Figure 4 As shown in FIG. 1 , an operation lever 42 of the lever 40 described later is located above the cover 30 at the mating start position. Figure 3 As shown, in the mating end position, the operating lever 42 is located above the rear end portion of the housing 20. That is, in the mating end position, the cover 30 is configured to protrude rearward from the lever 40. On the back side (rear side) of the housing 20, a wire harness W consisting of a plurality of wires (not shown) bundled together is led out rearward.

[0021] [case] The housing 20 is made of synthetic resin such as Figure 6 As shown, the housing 20 is formed into a substantially square block. The housing 20 has a plurality of cavities 21 that penetrate in the front-to-back direction. Terminals (not shown) are housed in the cavities 21, and the ends of the wires are connected to the terminals. Such wires are led out from each cavity 21 to the rear to form a wire bundle W that is a bundle of a plurality of wires. To simplify the drawing, the wire bundle W is drawn as a thick line with a double-dashed line.

[0022] The stopper 22 is mounted to the housing 20 from below. Although not shown, the stopper 22 is formed in a grid shape with openings at positions corresponding to the respective cavities 21. The stopper 22 can be in a temporary stop position ( Figure 5 Position shown) and the formal locking position ( Figure 6 When the stopper 22 is in the temporary stop position, the terminal can be inserted or removed. When the stopper 22 is in the formal stop position, the terminal can be prevented from falling off.

[0023] A pair of shafts 24 are protrudingly provided on both side surfaces 23 of the housing 20. The pair of shafts 24 are provided on each side surface 23 and are arranged symmetrically. A limiting piece 25 extending downward is provided at the top of the shaft 24. Figure 10 As shown, a pair of rod retaining locks 26 in a truncated cone shape are provided above the shaft portion 24 on both side surfaces 23 of the housing 20. The rod retaining locks 26 are provided on each side surface 23, respectively, and are disposed symmetrically.

[0024] [build] The cover 30 is made of a synthetic resin such as Figure 6As shown, it includes an upper wall 31, a lower wall 32 disposed opposite to the lower side of the upper wall 31, and a right side wall 33 connecting the right side edge of the upper wall 31 and the right side edge of the lower wall 32. Between the left side edge of the upper wall 31 and the left side edge of the lower wall 32 is an outlet 34 for leading out the wire harness W.

[0025] On the front edges of the upper wall 31 and the lower wall 32, there are a pair of upper and lower mounting ribs 35 extending in the left-right direction. On the other hand, as Figure 7 shown, at the rear end portion of the housing 20, there are a pair of mounted portions 27 for receiving the pair of upper and lower mounting ribs 35. During the process of inserting each mounting rib 35 into each mounted portion 27, the lid lock 35A formed at the end of each mounting rib 35 is engaged with a lock receiving portion (not shown) on the housing 20 side, so that the lid 30 is held on the housing 20.

[0026] As Figure 1 and Figure 2 shown, after the wire harness W is led out from the housing 20 to the rear, its direction is changed to the left rear obliquely by interfering with the right side wall 33, and it is led out to the outside of the lid 30 through the outlet 34.

[0027] [Rod] The rod 40 is made of synthetic resin and includes a pair of cam plates 41 and a U-shaped operating rod 42 connecting the pair of cam plates 41. The cam plate 41 has a circular hole-shaped bearing portion 47 for fitting the shaft portion 24 and a fan-shaped restriction receiving portion 43 for fitting the restriction piece 25. By housing the shaft portion 24 in the bearing portion 47, the rod 40 is supported in a rotatable manner. In addition, when the rod 40 is in the fitting start position, the rod 40 is prevented from accidentally rotating to the side opposite to the fitting end position by the abutment of one end of the restriction receiving portion 43 against the restriction piece 25, and when the rod 40 is in the fitting end position, the rod 40 is prevented from accidentally rotating to the side opposite to the fitting start position by the abutment of the other end of the restriction receiving portion 43 against the restriction piece 25.

[0028] As Figure 10 shown, the cam plate 41 has a track 44 for the cam pin 54 to enter. The track 44 has an inlet 44A opening to the side opposite to the bearing portion 47 at the outer edge of the cam plate 41, and is formed to gradually approach the bearing portion 47 as it goes from the inlet 44A toward the end 44B. When the rod 40 is in the fitting start position, if the rod-type connectors 10, 50 are fitted shallower, the cam pin 54 enters the inlet 44A of the track 44.

[0029] When the rod 40 is moved from the fitting start position to the fitting end position, the two connectors 10, 50 are fitted by the engagement of the cam pin 54 with the inner wall of the track 44. On the contrary, when the rod 40 is moved from the fitting end position to the fitting start position, the two connectors 10, 50 are disengaged by the engagement of the cam pin 54 with the inner wall of the track 44.

[0030] The operating lever 42 includes a pair of arm portions 45 connected to the outer edge of the cam plate 41, and an operating portion 46 connecting the tip portions 45A of the pair of arm portions 45. At Figure 10 the fitting start position shown, the rod holding lock 26 is engaged with the base end portion 45B of the arm portion 45 in a semi-lock state, thereby suppressing the movement of the rod 40 from the fitting start position to the fitting end position. At Figure 11 the fitting end position shown, the rod holding lock 26 is received in the space formed between the outer edge of the cam plate 41 and the base end portion 45B of the arm portion 45, so as not to interfere with the rod 40.

[0031] [Rod misrotation prevention mechanism] As described above, as a mechanism for suppressing the misrotation of the rod 40 at the fitting start position and the fitting end position, the rod-type connector 10 includes a locking structure formed by the restricting piece 25 of the housing 20 and the restricting receiving portion 43 of the rod 40. However, since the locking structure of the restricting piece 25 and the restricting receiving portion 43 is located close to the shaft portion 24, misrotation may not be suppressed when a large force acts on the rod 40.

[0032] In response to this, in the rod-type connector 10 of the present disclosure, as a mechanism for suppressing misrotation even when a large force acts on the rod 40, a rib 36 is provided on the cover 30. As Figure 10 shown, the rib 36 is disposed at the front end portion of the right side wall 33, which is the wall portion of the cover 30 located on the side opposite to the lead-out port 34. The rib 36 includes a first receiving portion 36A that abuts against the outer edge of the cam plate 41 at Figure 10 the fitting start position shown, a second receiving portion 36B that abuts against the outer edge of the cam plate 41 at Figure 11 the fitting end position shown, and an L-shaped reinforcing portion 36C connecting the first receiving portion 36A and the second receiving portion 36B.

[0033] The first receiving portion 36A has an inclined surface that slopes downward toward the front. The second receiving portion 36B has a vertical surface extending in the vertical direction. The front end (lower end) of the first receiving portion 36A is connected to the upper end of the second receiving portion 36B. The rear end (upper end) of the first receiving portion 36A is connected to the upper end of the reinforcing portion 36C. The lower end of the second receiving portion 36B is connected to the front end of the reinforcing portion 36C. Thus, the rib 36 is in the shape of a right trapezoid with the first receiving portion 36A as the hypotenuse. The vertical surface of the second receiving portion 36B is arranged to be aligned with the front end of the right side wall 33.

[0034] On the other hand, the outer edge of the cam plate 41 includes a first abutting portion 41A that abuts against the first receiving portion 36A at Figure 10 the fitting start position shown, and at Figure 11The second abutting portion 41B where the shown fitting end position abuts against the second receiving portion 36B. As Figure 11 shown, in the vertical direction orthogonal to the fitting direction of the rod-shaped connector 10 and the mating connector 50, the first abutting portion 41A is disposed above the shaft portion 24, and the second abutting portion 41B is disposed below the shaft portion 24. The first abutting portion 41A and the second abutting portion 41B are linearly continuous. Thus, when the first abutting portion 41A moves away from the first receiving portion 36A, the second abutting portion 41B approaches the second receiving portion 36B. On the contrary, when the second abutting portion 41B moves away from the second receiving portion 36B, the first abutting portion 41A approaches the first receiving portion 36A.

[0035] As Figure 10 shown, the first receiving portion 36A is formed longer than the second receiving portion 36B, and the length of the inclined surface of the first receiving portion 36A is about four times that of the vertical surface of the second receiving portion 36B. At the fitting start position, the first abutting portion 41A of the cam plate 41 abuts against the inclined surface of the first receiving portion 36A, thereby suppressing the rod 40 at the fitting start position from rotating erroneously to the side opposite to the fitting end position. In addition, at Figure 11 the fitting end position shown, the second abutting portion 41B of the cam plate 41 abuts against the vertical surface of the second receiving portion 36B, thereby suppressing the rod 40 at the fitting completion position from rotating erroneously to the side opposite to the fitting start position. Further, at the fitting end position, since the operating lever 42 abuts against the top wall 53C of the fitting recess 53 of the mating housing 51 from the front, the erroneous rotation of the rod 40 can also be suppressed.

[0036] The rib 36 is a single rib 36 located behind the shaft portion 24 and is a rib 36 integrally formed by the first receiving portion 36A and the second receiving portion 36B. Therefore, compared with the case where the first receiving portion and the second receiving portion are formed separately, miniaturization of the cover 30 is achieved. Since the cover 30 has the outlet 34, the strength may be reduced. However, since the pair of upper and lower mounting ribs 35 are firmly held by the mounting portion 27, deformation of the cover 30 can be avoided. Thus, even if a large force is applied to the rib 36 due to the erroneous rotation of the rod 40, the erroneous rotation of the rod 40 can be reliably suppressed.

[0037] [Operation of the Rod-shaped Connector] Next, the operation of the rod-shaped connector will be described. Figure 5Indicates the connector shipping state where the rod - type connector 10 is shipped from the connector assembly process to the wire harness manufacturing process. In the connector shipping state, the rod 40 is set at the fitting - end position, and the stopper 22 is set at the temporary locking position. Next, in the wire harness manufacturing process, the terminal connected to the end of the wire is inserted into the cavity 21 from the rear. At this time, since the rod 40 is at the fitting - end position, the terminal can be inserted into the cavity 21 without interfering with the rod 40. After all the terminals are inserted into the cavity 21, the stopper 22 is pushed from the temporary locking position to the formal locking position. Thereby, the terminal is held by the housing 20. Since all the terminals are connected to the ends of the wires, on the back surface of the housing 20, the wire harness W is led out rearward.

[0038] Figure 6 Shows the situation where the cover 30 is mounted on the back side of the housing 20 from the right side. In this state, since the rod 40 is still set at the fitting - end position, the cover 30 is mounted on the back side of the housing 20 without interfering with the rod 40. At this time, since the lead - out port 34 is provided on the cover 30, the cover 30 does not interfere with the wire harness W.

[0039] Figure 7 Shows from Figure 6 the state where the cover 30 is mounted on the back side of the housing 20. Since the pair of mounting ribs 35 of the cover 30 are fitted into the pair of mounted portions 27 of the housing 20 and are firmly held, even if the right - hand side wall 33 interferes with the wire harness W when mounting the cover 30, the cover 30 will not fall off from the housing 20, bends the direction of the wire harness W from the rear to the left - rear obliquely, and the wire harness W can be led out to the outside through the lead - out port 34.

[0040] Figure 8 Shows when Figure 7 the rod 40 in the state is moved from the fitting - end position to the fitting - start position. In this state, as Figure 10 shown, since the rod holding lock 26 interferes with the rod 40, the rod 40 is held at the fitting - start position. The rod - type connector 10 is shipped from the wire harness manufacturing process to the vehicle assembly process in Figure 8 this state.

[0041] Figure 9 Shows the connector fitting state where the rod - type connector 10 is fitted into the fitting recess 53 of the mating - side connector 50 in the vehicle assembly process. In the vehicle assembly process, after the rod - type connector 10 is shallowly fitted into the fitting recess 53, the fitting operation is performed by moving the rod 40 from the fitting - start position to the fitting - end position. As Figure 10As shown, in a state where the two connectors 10 and 50 are shallowly engaged by manual operation (temporary engagement setting state), since the cam plate 41 abuts against the top wall 53C of the mating-side housing 51, the rod 40 will not be arbitrarily rotated from the start position of engagement to the end position of engagement due to manual operation. When the operation is switched from manual operation to rod operation, the abutment against the top wall 53C is released due to the gap between the two connectors 10 and 50, allowing the rod 40 to rotate, and the cam pin 54 is introduced into the track 44. After that, when all the rod-type connectors 10 are engaged with all the engaging recesses 53 of the mating-side connector 50, the installation of the rod-type connector 10 in the vehicle assembly process is completed.

[0042] [Function and effect of Embodiment 1] The rod-type connector 10 of the present disclosure is a rod-type connector 10 that can be engaged with a mating-side connector 50, and includes: a housing 20; a rod 40 rotatably mounted on the housing 20; and a cover 30 mounted on the back side of the housing 20. The rod 40 can rotate between a start position of engagement and an end position of engagement. When moving from the start position of engagement to the end position of engagement, it engages with the mating-side connector 50. Conversely, when moving from the end position of engagement to the start position of engagement, it disengages from the mating-side connector 50. The cover 30 has a first receiving portion 36A and a second receiving portion 36B. Among them, the first receiving portion 36A inhibits the rod 40 located at the start position of engagement from accidentally rotating in the direction opposite to the end position of engagement, and the second receiving portion 36B inhibits the rod 40 located at the end position of engagement from accidentally rotating in the direction opposite to the start position of engagement. The first receiving portion 36A and the second receiving portion 36B are constituted by a single rib 36.

[0043] The above-mentioned rod-type connector 10 engages with the mating-side connector 50 by moving the rod 40 from the start position of engagement to the end position of engagement, and disengages from the mating-side connector 50 by moving the rod 40 from the end position of engagement to the start position of engagement. Here, when the rod 40 at the start position of engagement attempts to accidentally rotate in the direction opposite to the end position of engagement, the accidental rotation is inhibited by the first receiving portion 36A. In addition, when the rod 40 at the end position of engagement attempts to accidentally rotate in the direction opposite to the start position of engagement, the accidental rotation is inhibited by the second receiving portion 36B.

[0044] Here, since the first receiving portion 36A and the second receiving portion 36B are constituted by a single rib 36, compared with the case where the first receiving portion 36A and the second receiving portion 36B are respectively provided at different positions on the cover 30, the cover 30 can be made more space-saving, and the rod-type connector 10 as a whole can also be made more space-saving. Therefore, by using a single rib 36 to prevent the accidental rotation of the rod 40, the space-saving of the rod-type connector 10 can be achieved.

[0045] Preferably, the housing 20 has a shaft portion 24 that rotatably supports the rod 40. The rod 40 includes a first abutting portion 41A that abuts against the first receiving portion 36A at the start position of fitting; and a second abutting portion 41B that abuts against the second receiving portion 36B at the end position of fitting. In a direction crossing the fitting direction of the rod-type connector 10 and the mating connector 50, the first abutting portion 41A is disposed on one side of the shaft portion 24, and the second abutting portion 41B is disposed on the other side of the shaft portion 24. Since the first abutting portion 41A is disposed on one side of the shaft portion 24 and the second abutting portion 41B is disposed on the other side of the shaft portion 24, when the first abutting portion 41A moves away from the first receiving portion 36A of the rib 36, the second abutting portion 41B moves toward the second receiving portion 36B of the rib. Conversely, when the second abutting portion 41B moves away from the second receiving portion 36B of the rib 36, the first abutting portion 41A moves toward the first receiving portion 36A of the rib 36. Therefore, the erroneous rotation of the rod 40 can be suppressed by a single rib 36. In addition, since both the first abutting portion 41A and the second abutting portion 41B are provided at a thick portion of the rod 40, the erroneous rotation can be suppressed more firmly than in the case where the erroneous rotation is suppressed at a thin position such as the restricting piece 25 of the housing 20.

[0046] Preferably, the cover 30 has a lead-out port 34 that leads out the wire harness W drawn out from the back surface of the housing 20 in a direction different from its lead-out direction. The rib 36 is provided on the right side wall 33 of the cover 30 on the side opposite to the lead-out port 34. When the lead-out port 34 is provided on the cover 30, it is conceivable that the strength of the peripheral portion of the lead-out port 34 is reduced. In this regard, since the rib 36 is provided on the right side wall 33 of the cover 30 on the side opposite to the lead-out port 34, it is hardly affected by the strength reduction, and the erroneous rotation of the rod 40 can be reliably suppressed.

[0047] <Embodiment 2> While referring to Figure 13 the drawings, Embodiment 2 will be described. In Embodiment 1, an example in which the wire harnesses W of the three rod-type connectors 10 are all led out obliquely backward to the left is shown. However, in Embodiment 2, it is different from Embodiment 1 in that only the wire harness W of the leftmost rod-type connector 10R is led out obliquely backward to the right. The second and third rod-type connectors 10L from the left are the same as the rod-type connector 10 of Embodiment 1.

[0048] The rod - type connector 10R is provided with a right - exit cover 30R for guiding the wire harness W obliquely right - rearward, and the rod - type connector 10L is provided with a left - exit cover 30L for guiding the wire harness W obliquely left - rearward. The right - exit cover 30R and the left - exit cover 30L have a bilaterally symmetric shape, and the left - exit cover 30L is the same as the cover 30 in the first embodiment. In the rod - type connector 10R, the structure other than the right - exit cover 30R is the same as that of the rod - type connector 10 in the first embodiment.

[0049] In the second embodiment, an example of one right - exit cover 30R and two left - exit covers 30L is shown, but their combination is not limited to the combination in the second embodiment. For example, it can be two right - exit covers 30R and one left - exit cover 30L. In addition, the arrangement of each rod - type connector 10L, 10R is not limited to the arrangement in the second embodiment. For example, the rod - type connector 10R can also be arranged at the second position from the left. Regardless of the combination or arrangement, the wire harnesses W do not interfere with each other, and each rod - type connector 10L, 10R can be installed on the mating connector 50 on the other side. Thus, the freedom of wiring of the wire harness W is ensured.

[0050] <Embodiment 3> While referring to Figure 14 the drawings, Embodiment 3 will be described. There is no limitation on the fitting order with respect to the mating connector 50 in Embodiment 3. In Embodiment 3, the following situation is shown: First, the second rod - type connector 10 from the left is fitted, then the third rod - type connector 10 from the left is fitted, and finally the left - most rod - type connector 10 is fitted. The fitting order is not limited to the order in Embodiment 3. For example, the third rod - type connector 10 from the left can also be fitted first. Thus, the freedom of the fitting order is ensured.

[0051] <Other Embodiments> (1) In the above - mentioned first to third embodiments, an example where the first abutting portion 41A is arranged on the upper side of the shaft portion 24 and the second abutting portion 41B is arranged on the lower side of the shaft portion 24 is shown, but both the first abutting portion and the second abutting portion can also be arranged on the upper side of the shaft portion 24.

[0052] (2) In the above - mentioned first to third embodiments, an example where the rib 36 is provided on the wall portion on the side opposite to the lead - out port 34 is shown, but the rib can also be provided on the wall portion provided with the lead - out port.

[0053] (3) In the above - mentioned first embodiment, as Figure 1 shown, an example of three rod - type connectors 10L having a left - exit cover 30L is shown, but as Figure 12 shown, it can also be three rod - type connectors 10R having a right - exit cover 30R. Explanation of Reference Numerals
