Description

  The present invention relates to an assembling structure of a switch body and a connector for assembling a connector to a switch body and connecting a harness on the connector side and a harness on the switch body side.

  2. Description of the Related Art Conventionally, for example, a motorcycle has an assembly structure of a switch body and a connector, in which a connector is assembled to a switch body and a harness on the connector side and a harness on the switch body side are connected. In such an assembly structure of the switch body and the connector, since the connector is generally fixed to the switch body with screws, there is a problem that the number of parts increases and the manufacturing process increases and the cost increases. is there. For this reason, an assembly structure of a switch body and a connector for assembling the connector to the switch body without using a screw has been developed (see, for example, Patent Document 1).

  This switch body / connector assembly structure (a structure in which a steering roll connector and a combination switch are combined) is configured by attaching a substantially donut-shaped steering roll connector to the combination switch. Three engagement pieces are formed. The combination switch is formed in a box shape, and three lock members are provided on the upper wall so as to correspond to the engagement pieces of the steering roll connector. The lock member includes an arcuate guide arc side wall, a positioning side wall and a stopper side wall that extend from both ends of the guide arc side wall to the steering roll connector, and an upper wall. Is formed with an insertion opening.

  In addition, an arcuate opening is formed on the steering roll connector side, and a claw having a downward tapered surface from the positioning side wall to the stopper side wall is formed at the tip of the positioning side wall on the lower surface of the upper wall. Yes. For this reason, after inserting the three engagement pieces into the lock member from the insertion openings and assembling the steering roll connector to the combination switch, the steering roll connector is rotated to engage the engagement pieces with the claws. By combining, the steering roll connector and the combination switch can be combined.

JP 2001-57278 A

  However, since the above-described conventional switch body and connector assembly structure is installed around the steering shaft, the connection portion of the combination switch to which the steering roll connector is assembled penetrates the steering shaft in the combination switch. Limited to around the hole. Further, since the claw that engages with the engagement piece is located only on one surface side of the engagement piece, the upper wall is bent more greatly when the engagement piece is engaged with the claw, and the upper wall has a larger deflection. There is a problem that load is applied.

  The present invention has been made in order to cope with the above-described problems. The purpose of the present invention is to arbitrarily set the connection position of the connector with respect to the switch body and to apply a large load to the portion of the switch body that engages with the connector. It is an object to provide an assembly structure of a switch body and a connector that can prevent this. In addition, in the description of each component requirement of the present invention below, in order to facilitate understanding of the present invention, the reference numerals of corresponding portions of the embodiment are described in parentheses, but the component requirement of the present invention is not implemented. The present invention should not be construed as being limited to the configurations of the corresponding portions indicated by the reference numerals of the forms.

  In order to achieve the above object, the structural feature of the assembly structure of the switch body and the connector according to the present invention is that the connector (20) is assembled to the connection portion (13) of the switch body (10) to which the switch is attached. The assembly (A) of the switch body and the connector that extends the harnesses (a, b) connected to the connector to the switch body side, and a pair of engagement frames having flexibility at the connection portion Portions (17, 18) are provided in parallel with the space in the frame facing each other, and when the connector is assembled to the connector to the connector, the front end side of the engagement frame between the pair of engagement frames The insertion portion (27) that can be inserted from the side, and formed on both sides of the insertion portion, when the insertion portion is inserted between the pair of engagement frame portions, the pair of engagement frame portions are spread and expanded. Into the frame of the pair of engaging frames, respectively. A pair of engaging claws (27a, 27b) to return to the original state the pair of engagement frames portions after entering the in that is provided.

  In the assembly structure of the switch body and the connector according to the present invention, the connector body is provided with a pair of flexible engagement frame portions in parallel at the connection portion of the switch body, and is assembled to the connection portion of the switch body. Is provided with an insertion portion that can be inserted between a pair of engagement frame portions, and engagement claws formed on both sides of the insertion portion. When the connector is assembled to the connection portion, the insertion portion is inserted between the pair of engagement frame portions from the distal end side of the pair of engagement frame portions. The parts are spread and enter into the frames of the pair of engaging frame parts. Further, after the pair of engaging claws enter the frames of the pair of engaging frame portions, the pair of engaging frame portions returns to the original state. As a result, the pair of engagement frame portions and the pair of engagement claws are engaged, and the connector is assembled to the switch body.

  As described above, in the present invention, the insertion portion of the connector enters between the pair of engagement frame portions from the distal end side of the pair of engagement frame portions, that is, the connector approaches from a position far from the switch body. Therefore, it is assembled | attached by engagement with a pair of engagement frame part and a pair of engagement nail | claw. For this reason, the place which provides the connection part in a switch main body is not specifically limited, It can set to arbitrary positions. Further, when the pair of engaging claws engage with the pair of engaging frame portions, the respective engaging frame portions are bent in the same manner, so that only one of the engaging frame portions is not loaded. For this reason, it becomes difficult to produce damage to a pair of engagement frame parts.

  Another structural feature of the assembly structure of the switch body and the connector according to the present invention is that the pair of engaging frame portions include lateral pieces (17c, 18c) positioned on the connector side, When the pair of engaging claws are engaged with the lateral pieces of the pair of engaging frame portions, a restraining wall (21) that comes into contact with the distal end portions of the pair of engaging frame portions is included. This is because the connector cannot be moved forward and backward with respect to the switch body when engaged with the engagement frame portion.

  According to the present invention, when the connector is moved to the switch body side from the state where the switch body and the connector are assembled, the stop wall comes into contact with the distal ends of the pair of engagement frame portions, and the connector cannot move. When the connector tries to move away from the switch body, the pair of engaging claws abut against the lateral pieces of the pair of engaging frame portions, and the connector cannot move. For this reason, a connector is hold | maintained in the state located in the appropriate position with respect to a switch main body.

(14b, 14c, 14d) formed on one side and a recess (14) formed on one side and a guide wall (16) formed on the side where the recess is opened. Is in contact with the three side surfaces forming the guide wall.

  According to the present invention, the side surface of the connector is surrounded by the three side surface portions that form the recesses and the guide wall even if the connector attempts to move laterally with respect to the switch body from the assembled state of the switch body and the connector. It is not possible to move. For this reason, a connector is hold | maintained in the state located in the appropriate position with respect to a switch main body.

  Still another structural feature of the assembly structure of the switch body and the connector according to the present invention is that the inner surface of the three side surface portions extends in the insertion direction when the insertion portion is inserted between the pair of engagement frame portions. The protrusions (15a, 15b, 15c) are formed respectively, and the connector is provided with side portions (22, 24, 26) facing the inner surfaces of the three side surface portions, respectively. The side portions are in contact with each other.

  According to the present invention, it is possible to prevent the connector from rattling against the switch body. When trying to make the side part which forms a concave part and the side part of a connector contact the whole surface, if both sides are not formed on a precise and smooth surface, a gap may be formed, Such a rattling can be prevented by bringing the side portions into contact with each other.

  Still another structural feature of the assembly structure of the switch body and the connector according to the present invention is that the connector is formed with an engagement groove (25d) that allows the connector to slide while being engaged with the guide wall. There is in being.

  According to the present invention, when the connector is assembled to the switch body, the engagement groove is slidably engaged with the guide wall, so that smooth assembly is possible. In addition, since the guide wall is formed in the switch body and the engaging groove is formed in the connector, the connector is not mistakenly attached to the switch body.

  Still another structural feature of the assembly structure of the switch main body and the connector according to the present invention is that an insertion hole (19) for passing a harness is formed in the switch main body, and the pair of engagement frame portions are in the vicinity of the insertion hole. It is in being provided.

  According to the present invention, the connection portion can be provided in a minimum space, and the switch body can be downsized.

  Still another structural feature of the assembly structure of the switch body and the connector according to the present invention is that taper surfaces (17d, 18d) are respectively formed on the distal end portions of the pair of engagement frame portions and the outer surfaces of the pair of engagement claws. 27c, 27d) is formed, and the distance between the distal end portions of the pair of engaging frame portions becomes wider as the distal ends of the pair of engaging frame portions are wider toward the proximal end portions of the pair of engaging frame portions, The width between the outer surfaces of the pair of engaging claws is that the distal end side of the pair of engaging claws is narrow and becomes wider as the distance from the distal ends of the pair of engaging claws is increased.

  According to the present invention, when the connector is assembled to the switch body, first, the narrower width between the outer surfaces of the pair of engaging claws hits the wider interval between the tip portions of the pair of engaging frame portions, The pair of engaging claws try to enter the pair of engaging frame portions while gradually increasing the interval between the distal end portions of the engaging frame portions. For this reason, a pair of engagement nail | claw and a pair of engagement frame part can be engaged smoothly.

  The connector 20 configured in this manner is lowered from the state shown in FIG. 3, and a lower side portion (a portion below the positioning convex portion 25 e) is located between the positioning concave portion 14 of the connecting portion 13 and the guide wall 16. Is assembled to the switch body 10. In this case, as shown in FIG. 8, the connector 20 first passes the harness a through the insertion hole 19 and extends the harness b to the upper surface side of the bottom portion 11 so that the lower end portion of the engagement groove 25d is connected to the guide wall. It descends according to the upper end of 16. At this time, since the width of the upper end portion of the guide wall 16 is narrow, it is easy to align the lower end portion of the engagement groove 25d and the upper end portion of the guide wall 16, and by lowering the connector 20, The engagement groove 25d and the guide wall 16 are smoothly slidably engaged.

  At that time, the front wall portion 22 contacts the protrusion 15b, the right side portion 24 contacts the protrusion 15a, and the contact wall 26 contacts the protrusion 15c. For this reason, even if the inner surfaces of the side surface portions 14b, 14c, and 14d are not flat surfaces with high accuracy, even if they are slightly distorted surfaces, the connector 20 is lowered without rattling. Then, after the lower end portion of the insertion portion 27 comes into contact with the upper end portions of the engagement frame portions 17 and 18, the insertion portion 27 tends to enter between the engagement frame portions 17 and 18. At that time, the tapered surfaces 27c and 27d of the engaging claws 27a and 27b abut against the tapered surfaces 17d and 18d of the engaging frame portions 17 and 18, and the inserting portion 27 is further lowered, so that the engaging claws are lowered. 27a and 27b increase the interval between the engagement frame portions 17 and 18. When the engaging claws 27a and 27b reach the lower side of the horizontal pieces 17c and 18c beyond the horizontal pieces 17c and 18c, the engaging claws 27a and 27b enter the space in the frame of the engaging frame portions 17 and 18. Positioned, the engagement frame portions 17 and 18 return to the original state and become the state of FIG.

  At this time, as shown in FIG. 10, the upper surfaces of the engaging claws 27 a and 27 b are in contact with the lower edge portions of the lateral pieces 17 c and 18 c, and the upper end portions of the engaging frame portions 17 and 18 are on the bottom surface portion 21. Contact the lower surface. That is, the bottom surface portion 21 constitutes a stop wall according to the present invention. Further, the positioning convex portion 25 e is engaged with the concave portion 16 a of the guide wall 16. As a result, the connector 20 is prevented from being displaced in the vertical direction with respect to the switch body 10. Further, displacement of the connector 20 from front to back and from side to side is prevented by the guide wall 16 and the ridges 15a, 15b, and 15c described above. For this reason, the connector 20 is held in a state assembled to the switch body 10 without any positional deviation. Moreover, the front-end | tip part of the harness a and the harness b is connected to the terminal etc. of a predetermined member.

The connector 20 assembled to the connection portion 13 has an insertion portion 27 that can be inserted between the engagement frame portions 17 and 18 and can be engaged in the frame of the engagement frame portions 17 and 18 that are formed on both sides of the insertion portion 27. Engaging claws 27a and 27b are provided. When the connector 20 is assembled to the connection portion 13, the insertion portion 27 is inserted between the engagement frame portions 17 and 18, and the engagement claws 27 a and 27 b push the engagement frame portions 17 and 18 apart. After entering into the frame of the engagement frame parts 17 and 18 respectively, and engaging claw 27a, 27b engaging with the engagement frame parts 17 and 18, the engagement frame parts 17 and 18 return to the original state. As a result, the connector 20 is assembled to the switch body 10.

  Thus, in the present invention, the connector 20 is not assembled to the switch body 10 while rotating around the insertion hole 11a, but the connector 20 is lowered from above with respect to the switch body 10 and assembled to the connection portion 13. ing. For this reason, the place which provides the connection part 13 in the switch main body 10 can be set to arbitrary positions. In the present invention, since the connection portion 13 is provided in a portion where the insertion hole 19 for passing the harness a in the switch body 10 is located, it is not necessary to arrange the harness a in the switch body 10 along the bottom portion 11. The connecting portion 13 can be provided in a minimum space, and the switch body 10 can be downsized.

  Further, when the connector 20 is assembled to the switch body 10, the engagement groove 25 d is slidably engaged with the guide wall 16 whose upper end side is narrow, so that smooth assembly is possible and the orientation of the connector 20 No mistakes will be made to assemble the switch body 10. Further, by forming the tapered surfaces 27c and 27d on the engaging claws 27a and 27b and forming the tapered surfaces 17d and 18d on the engaging frame portions 17 and 18, the engaging claws 27a and 27b and the engaging frame portions 17 and 18 are formed. 18 can be engaged smoothly.

  Further, in the state where the connector 20 is assembled to the switch body 10, the engagement between the engagement claws 27 a and 27 b and the horizontal pieces 17 c and 18 c and the contact between the engagement frame portions 17 and 18 and the bottom surface portion 21, The connector 20 is prevented from being displaced in the vertical direction with respect to the switch body 10. Further, the connector 20 is prevented from being displaced from front to back and from side to side by contacting the guide wall 16 and the protrusions 15a, 15b and 15c. For this reason, the connector 20 is not displaced relative to the switch body 10, and the harness a and the harness b are maintained in a properly disposed state.
