Description

  The present invention relates to a connector.

  In Patent Document 1, as a means for fitting a pair of housings, a lever type in which both housings are fitted by rotating a lever provided on one housing from an initial position to a fitting position. A connector is disclosed. This connector is provided with means for ensuring that both housings are in a properly fitted state.

  The guarantee means includes an elastic lock piece provided on the lever and a lock portion provided on the housing. When the lever reaches the fitting position and the two housings are properly fitted, the elastic locking piece is locked to the locking portion, and the lever is locked to the fitting position by this locking action. Since the locking between the elastic lock piece and the lock portion is performed in a state that is visible on the back surface of the housing, whether or not the two housings are properly fitted depends on whether the elastic lock piece and the lock portion are locked. This can be confirmed by visual inspection.

  When the connector is downsized, the elastic lock piece and the lock portion are also downsized accordingly, and it is difficult to visually determine whether or not the elastic lock piece and the lock portion are correctly locked.

  As a countermeasure, a through hole is formed in the housing, a through hole is also formed in the lever, and both the through holes are coaxially aligned when the lever reaches the fitting position. A method is conceivable in which a wire is passed through the through-hole and the both ends of the wire are entangled and fixed.

According to this method, it can be assured that both the housings are properly fitted with the wires being attached. Further, even if the connector is small, a thick wire or a long wire can be used, so that the presence or absence of the wire can be easily and reliably visually confirmed.
JP-A-9-213413

  However, in the method using the wire, when the moving direction when reaching the fitting position of the lever is substantially the same direction as the penetrating direction of the through hole, the lever has not reached the normal fitting position. However, since the through-holes are close to each other in a substantially coaxial manner when approaching the normal fitting position, it is possible to pass the wires through both through-holes. For this reason, there is a concern that the operator may accidentally pass the wires through the two through-holes even though the two housings are not in the proper fitted state.

  The present invention has been completed based on the above-described circumstances, and an object thereof is to improve the reliability of a function for guaranteeing that the housings are properly fitted to each other.

  As means for achieving the above object, the invention of claim 1 is directed to a first housing, a second housing that can be fitted to the first housing, and a fitting between the first housing and the second housing. In the process, the first housing and the second housing are elastically displaced when they are in a half-fitted state immediately before the normal fitting, and the first housing and the second housing are elastically restored when the normal fitting state is reached. A first through hole formed through the elastic bending piece in a direction intersecting the elastic bending direction of the elastic bending piece, and the insertion of the wire. In a state where the elastic bending piece is elastically displaced, it is inconsistent with the first through hole, and at least a part of the opening region of the first through hole when the elastic bending piece is elastically restored. Consistent with Characterized in place and a second through hole that.

  According to a second aspect of the present invention, in the first aspect, the elastic bending piece has a function as a lock means capable of holding the first housing and the second housing in a properly fitted state. However, it has characteristics.

  According to a third aspect of the present invention, in the second aspect of the present invention, in the process of fitting the first housing and the second housing, substantially parallel to the penetrating direction of the first through hole with respect to the elastic bending piece. A lock portion that presses and elastically deforms the elastic bending piece while relatively moving is provided, the second through hole is formed in the lock portion, and the first housing and the second housing are in a half-fitted state The first through hole and the second through hole are characterized in that they wrap in the penetrating direction.

  According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the first housing and the second housing are provided in the first housing by a boosting action caused by locking between the cam function portion and the cam follower. When the first housing and the second housing are properly fitted to each other, the elastic flexure piece that has been elastically restored is in a rotation-restricted state with respect to the lever. It is characterized in that it can be locked to.

  According to a fifth aspect of the present invention, in any one of the first to fourth aspects, at least one of the first through hole and the second through hole has a through length. It is characterized in that the dimensions are larger than the inner diameter.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the formation base of the elastic bending piece and the formation base of the second through hole are engaged with each other, Restricting means is provided for restricting displacement of the first through hole and the second through hole in a direction intersecting both the penetrating direction of the first through hole and the elastic deflecting direction of the elastic deflecting piece. It has a characteristic where it exists.

<Invention of Claim 1>
When the first housing and the second housing are in a semi-fitted state immediately before the normal fitting, the first through hole and the second through hole are not aligned and are positioned in a direction crossing the through direction of the first through hole. Since it has shifted | deviated, it is difficult to let a wire penetrate to both through-holes. When the fitting of the two housings slightly progresses and the two housings reach a normal fitting state, the first through hole and the second through hole are aligned, so that the wires can be inserted into both the through holes. And it is guaranteed that both housings are properly fitted when the wires are inserted through both the first through hole and the second through hole.

  Since the penetration direction of the first through hole is a direction that intersects with the elastic deflection direction of the elastic deflection piece that is the formation base of the first through hole, the first housing and the second housing immediately before the normal fitting. When in the half-fitted state, a situation in which the first through hole and the second through hole approach substantially coaxially does not occur. Therefore, it can be avoided that the wire is inserted into both the first through hole and the second through hole in spite of the half-fitted state.

<Invention of Claim 2>
Since the elastic bending piece is provided with a function of locking both housings in the normal fitting state, the structure can be simplified compared to a connector in which the elastic bending piece and the locking means are provided separately.

<Invention of Claim 3>
When the two housings are half-fitted, the first through hole and the second through hole are positioned so as not to align the opening regions with each other and wrap in the through direction. A wire cannot be inserted into the cable.

<Invention of Claim 4>
When the levers are rotated and the two housings are brought into the normal fitting state, the elastic bent pieces that are elastically restored are locked to the levers, so that the levers are restricted. When the lever is restricted from rotating, both housings are locked so as not to be detached by the locking of the cam function portion and the cam follower.

<Invention of Claim 5>
Since the through length of at least one of the first through hole and the second through hole is larger than the inner diameter, it is difficult for the wire to be inserted obliquely into the through hole. Therefore, there is no possibility that the wire is inserted into both the through holes when the first through hole and the second through hole are not aligned.

<Invention of Claim 6>
The displacement of the first through hole and the second through hole in the direction intersecting the penetrating direction of the first through hole and the elastic bending direction of the elastic bending piece is restricted by the engaging action of the restricting means. The operation of inserting the through hole into the first through hole and the second through hole can be easily and reliably performed.

<Embodiment 1>
A first embodiment of the present invention will be described below with reference to FIGS. The connector of this embodiment is for fitting the first housing 10 that can be fitted to each other (the forming base of the elastic bending piece 13 that is a constituent element of the present invention), the second housing 30, and both the housings 10, 30. And a lever 20. In the following description, in the front-rear direction, the right side in FIGS. 2 and 6 is referred to as the front.

  The first housing 10 is made of synthetic resin, and a plurality of first terminal fittings (not shown) are attached to the first housing 10. A slit 12 having a substantially “U” shape (substantially U-shaped) is formed in the upper surface wall 11 that is inclined forward and constituting the first housing 10, and a region surrounded by the slit 12 in the upper surface wall 11 is The elastic bending piece 13 is elastically bent in the vertical direction with the upper end edge in the horizontal direction as a fulcrum. The elastic bending piece 13 protrudes upward from the center position in the left-right direction at the plate-like main body portion 14 extending obliquely downward and forward from the fulcrum of the elastic deformation, and the extending end portion (lower end portion) of the main body portion 14. And a lock projection 15 of the form. When the elastic bending piece 13 is in a free state (locked position) where the elastic bending piece 13 is not elastically bent, the lock protrusion 15 protrudes above the upper surface wall 11 and onto the movement path of the lock portion 26 of the lever 20 described later. Further, in a state where the elastic bending piece 13 is elastically displaced to the unlocking position obliquely downward and rearward, the lock protrusion 15 is retracted downward from the movement path of the lock portion 26.

  In addition, a pair of left and right regulating ribs 16 (regulating means that is a constituent feature of the present invention) are formed on the top wall 11 so as to sandwich the lock protrusion 15. The restriction rib 16 protrudes upward from the upper surface wall 11 and extends from the front lower end position to the rear upper end position along a rotation trajectory of the operation portion 21 of the lever 20 described later. The lock protrusion 15 is protected by a pair of restriction ribs 16 from foreign matter interference from obliquely upward and forward. Further, a pair of support shafts 17 for supporting the lever 20 is formed on the outer side surfaces of the left and right side walls constituting the first housing 10 so as to protrude.

  The lever 20 (the formation base of the second through-hole 28 which is a constituent element of the present invention) has a thick plate-like operation portion 21 extending in the left-right direction, and extends substantially at right angles from the left and right ends of the operation portion 21. A pair of arm portions 22 are configured to be engaged with each other by fitting the bearing hole 23 of the arm portion 22 to the support shaft 17 so that the initial position (see FIG. 7) and the fitting position ( 1 (see FIG. 1, FIG. 2 and FIG. 8). When the lever 20 is rotated from the initial position to the fitting position, the operation portion 21 is displaced in an arc shape along the outer surface of the upper surface wall 11 and the front wall connected to the lower end of the upper surface wall 11, and both arm portions 22 are moved. Is displaced along the outer surface of the side wall. Further, the arm portion 22 is formed with a cam function portion 24 including a plurality of locking projections spaced in the rotation direction of the lever 20.

  The operating portion 21 of the lever 20 is formed with a pair of left and right restricting grooves 25 (regulating means which is a constituent feature of the present invention) in a form in which an inner surface facing the upper surface wall 11 is cut away. The restriction groove 25 is formed from the front end edge to the rear end edge of the operation unit 21 so as to follow the displacement locus of the operation unit 21 accompanying the rotation of the lever 20. The pair of restriction grooves 25 are engaged in a state in which the lever 20 does not hinder the rotation of the lever 20 with respect to the pair of restriction ribs 16 while the lever 20 is rotated from a substantially intermediate position between the initial position and the fitting position to the fitting position. Match. Due to this engaging action, the operation unit 21 is restricted from moving relative to the first housing 10 in the left-right direction (the direction intersecting the displacement direction of the operation unit 21). Further, a region between the pair of restriction grooves 25 in the operation portion 21 is a lock portion 26.

  The second housing 30 is made of synthetic resin, and a second terminal fitting 31 is attached to the second housing 30. The second housing 30 is formed with a pair of left and right protruding cam followers 32 projecting in a direction substantially perpendicular to the fitting direction of the two housings 10 and 30.

  When the two housings 10 and 30 are fitted, the two housings 10 and 30 are shallowly fitted while the lever 20 is in the initial position, and the cam function portion 24 and the cam follower 32 are engaged. When the lever 20 is rotated from this state toward the mating position, the two housings 10 and 30 are attracted by the boosting action caused by the engagement between the cam function portion 24 and the cam follower 32.

  When the lever 20 is in the half-fitting position immediately before the lever 20 reaches the fitting position in the process of rotating the lever 20 from the initial position to the fitting position side (that is, when both the housings 10 and 30 are in the half-fitted state). 6), as shown in FIG. 6, the lock portion 26 makes its lower surface abut against the lock protrusion 15 obliquely from above and presses the lock protrusion 15 obliquely downward and rearward. Due to this pressing action, the elastic bending piece 13 is elastically displaced to the unlocking position, and accordingly, the lock protrusion 15 is also displaced obliquely downward and rearward.

  Then, when the lever 20 reaches the fitting position from the half-fitted state, both the housings 10 and 30 are brought into a normal fitting state so that the first terminal fitting (not shown) and the second terminal fitting 31 can conduct. Connected. Further, when the lever 20 reaches the fitting position, the lock portion 26 passes through the lock protrusion 15, so that the elastic bending piece 13 is elastically returned to the lock position. In this state, as shown in FIG. 2, the lock portion 26 is positioned closer to the upper and rear of the lock protrusion 15, and the rear end surface of the lock protrusion 15 and the front end surface of the lock portion 26 face each other. As a result, the lock portion 26 and the lock projection 15 are locked, and the locking action restricts the forward displacement of the lock portion 26, that is, the return of the lever 20 to the initial position. Thus, in the locked state in which the lever 20 is restricted from rotating to the initial position, the detachment of both the housings 10 and 30 is restricted by the locking of the cam function portion 24 and the cam follower 32, and thereby , 30 are locked in the normal fitting state.

  When the two housings 10 and 30 that are normally fitted are removed, the lock protrusion 15 of the elastic bending piece 13 is pushed to elastically displace the elastic bending piece 13 to the unlocking position obliquely downward and rearward. The locking with the portion 26, that is, the locked state that restricts the rotation of the lever 20 and the locked state that restricts the detachment of the housings 10 and 30 are released. Thereafter, when the lever 20 is rotated to the initial position side, both the housings 10 and 30 are detached by the cam action by the engagement of the cam function portion 24 and the cam follower 32.

  In the present embodiment, it is possible to guarantee by using the wire W that both the housings 10 and 30 have reached the normal fitting state. The guarantee means will be described below.

  The lock projection 15 of the elastic deflecting piece 13 is formed with a first through hole 18 that linearly penetrates from the front end face to the rear end face, and has a circular cross section perpendicular to the penetration direction. Yes. The penetration length dimension of the first through hole 18 is larger than the inner diameter dimension thereof. Further, the penetration direction of the first through hole 18 is a direction (a substantially perpendicular direction) intersecting the elastic displacement direction of the elastic bending piece 13. In other words, the penetrating direction of the first through hole 18 is substantially parallel to the movement locus of the lock portion 26 when the lever 20 is moved from the half-fitted state to the normal fitted state. Further, when the elastic deflecting piece 13 is in the locked position, the first through hole 18 is positioned above the upper surface of the upper surface wall 11.

  On the other hand, the lock portion 26 of the lever 20 is formed with a second through hole 28 having a shape that penetrates the lock portion 26 linearly in a direction substantially parallel to the moving direction thereof. The cross-sectional shape perpendicular to the penetrating direction of the second through hole 28 is circular, and the inner diameter thereof is substantially the same as the inner diameter of the first through hole 18. Further, the penetrating length dimension of the second through hole 28 is larger than the inner diameter dimension thereof. The lock portion 26 in which the second through hole 28 is formed is substantially parallel to the penetrating direction of the first through hole 18 with respect to the elastic bending piece 13 in the process of rotating the lever 20 from the initial position to the fitting position. The lock projection 15 of the elastic bending piece 13 is pressed while being relatively moved, and is elastically bent to the unlocking position.

  In the process of turning the lever 20 from the initial position to the fitting position side, as shown in FIG. 6, the half-fitting position immediately before the lever 20 reaches the fitting position (that is, the housings 10 and 30 are half-fitted). In the state), the lock portion 26 makes its lower surface abut against the lock protrusion 15 obliquely from above and presses the lock protrusion 15 obliquely downward and rearward. Due to this pressing action, the elastic bending piece 13 is elastically displaced to the unlocking position, and accordingly, the lock protrusion 15 is also displaced obliquely downward and rearward.

  In this state, the first through hole 18 formed in the lock protrusion 15 is displaced downward with respect to the second through hole 28 formed in the lock portion 26, so that the first through hole 18 on the front end side of the first through hole 18 is shifted. The opening is hidden behind the upper surface wall 11 of the housing. Therefore, even if it is going to let the wire W penetrate the 1st through-hole 18 from the front, it is difficult to insert into the 1st through-hole 18 from the front.

  Further, the substantially front end side portion of the second through hole 28 is in a state of wrapping with at least a part of the first through hole 18 in the penetrating direction, and the opening on the front end side of the second through hole 28 is the first through hole 18. The positions of the through holes 18 and 28 are not aligned at all. Therefore, even if the wire W can be inserted into the first through hole 18 from the front and protruded rearward, the protruding portion of the wire W cannot be inserted into the second through hole 28 from the front. Similarly, even if the wire W penetrates the second through hole 28 from the rear and protrudes forward, the protruding portion of the wire W cannot be inserted into the first through hole 18 from the rear.

  As described above, when the housings 10 and 30 are in the half-fitted state, the first through hole 18 and the second through hole 28 are not aligned so as to be coaxially arranged. It cannot be smoothly inserted through the second through hole 28. That is, when the wire W is not inserted into the through holes 18 and 28, the lever 20 is not properly rotated to the fitting position, and the two housings 10 and 30 are not half-fitted. There is a possibility that

  Now, when the lever 20 is rotated to the fitting position after passing through the above-mentioned half-fitted state, the lock portion 26 passes through the lock projection 15 and the elastic bending piece 13 is elastically returned to the lock position, as shown in FIG. As described above, the rear end surface of the lock protrusion 15 and the front end surface of the lock portion 26 face each other in a state of approaching so as to leave a slight gap narrower than the outer diameter of the wire W. The second through hole 28 is positioned in the vicinity of the rear of the first through hole 18, and the entire opening region of the opening on the front end side of the second through hole 28 and the entire opening of the opening on the rear end side of the first through hole 18 are provided. The area is aligned and opposed across the entire area. That is, the first through hole 18 and the second through hole 28 have a positional relationship in which both center lines are coaxially arranged, that is, the first through hole 18 and the second through hole 28 are parallel to each other. Position them so that they are lined up in the front and back.

  In this state, the lock protrusion 15 protrudes upward from the top wall 11, so that the wire W can be inserted into the first through hole 18 from the front. The inserted wire W passes through the first through hole 18, is inserted into the second through hole 28, and protrudes from the opening on the rear end side of the second through hole 28. When the protruding portion of the wire W and the portion remaining in front of the first through hole 18 are twisted and bound, the fitting operation of both the housings 10 and 30 is completed. Note that the wire W may be inserted into the second through hole 28 from the rear, penetrate the first through hole 18 and protrude forward. As described above, the wire W is inserted into the first through hole 18 and the second through hole 28, thereby ensuring that the housings 10 and 30 are properly fitted.

  As described above, in the present embodiment, the penetration direction of the first through-hole 18 is a direction that intersects the elastic deflection direction of the elastic deflection piece 13 that is the base for forming the first through-hole 18. In the process of fitting the housing 10 and the second housing 30, when the two housings 10 and 30 are in a semi-fitted state immediately before the normal fitting, the first through hole 18 and the second through hole 28 are substantially The situation of approaching coaxially does not occur. Therefore, it is possible to prevent the wire W from being inserted into both the first through hole 18 and the second through hole 28 in spite of being in a half-fitted state. That is, according to this embodiment, the reliability of the function which ensures that the housings 10 and 30 are correctly fitted is high.

  In addition, since the penetration length of the first through hole 18 is larger than the inner diameter of the first through hole 18, the wire W sufficiently thinner than the inner diameter is inserted into the first through hole 18. Even if it exists, there is no possibility that the wire W may be inserted in an oblique posture that is greatly inclined with respect to the axis (through direction) of the first through hole 18. Similarly, since the penetrating length of the second through hole 28 is larger than the inner diameter, there is no possibility that the wire W is inserted obliquely into the second through hole 28. Therefore, it is possible to avoid a situation in which the wire W is inserted into the through holes 18 and 28 even though the first through hole 18 and the second through hole 28 are not aligned.

  Further, the lock portion 26 (operation portion 21) of the lever 20 is fitted to the pair of left and right restricting ribs 16 and the pair of left and right restricting grooves 25 in the left-right direction (with respect to the first housing 10 (elastic bending piece 13)). Since the displacement of the first through hole 18 in the direction intersecting with the penetrating direction of the first through hole 18 and the direction intersecting the elastic deflecting direction of the elastic deflecting piece 13 is restricted, the first through hole 18 and the second through hole are regulated. The hole 28 is not displaced in the left-right direction. Therefore, there is no possibility that the operation of inserting the wire W into the through holes 18 and 28 will be hindered due to the displacement of the lock portion 26 in the left-right direction with respect to the first housing 10.
