Description

  The present invention relates to a connector having a fitting detection function.

  Conventionally, some connectors 1 are provided with a detection terminal 2 to electrically detect whether or not male and female connector housings 3 and 5 are properly fitted as shown in FIG. (See Patent Document 1). One connector housing 3 includes a pair of detection terminals 2 and a support piece 4 extending along the upper surface of the detection terminals 2. In the other connector housing 5, when both the connector housings 3, 5 are properly fitted, the short-circuit terminal 6 that contacts both the detection terminals 2 and short-circuits them, and both the connector housings 3, 5 are in a fitted state. A lock arm 7 for locking is provided. The short-circuit terminal 6 is provided with a contact portion 6A that comes into contact with the detection terminal 2.

In the middle of fitting the connector housings 3 and 5 (half-fitted state), the short-circuit terminal 6 is moved from the detection terminal 2 in conjunction with the bending operation of the lock arm 7 by utilizing the deformation of the lock arm 7. By deforming to retract, the contact portion 6A of the short-circuit terminal 6 and the detection terminal 2 are prevented from contacting each other. On the contrary, when both the connector housings 3 and 5 are properly fitted, the short-circuit terminal 6 is restored by using the return operation of the lock arm 7, and the contact portion 6A of the short-circuit terminal 6 and the detection terminal 2 are brought into contact with each other. The detection terminals 2 are short-circuited.

<Embodiment>
An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a side sectional view of the airbag connector constituting the connector 10 of the present embodiment before the male and female connector housings 11 and 30 are fitted. The right side of Figure 1 the male connector housing 1 1 is shown, the female connector housing 3 0 is shown on the left. In the following description, the direction in which the connector housings 11 and 30 are fitted together is the front direction. Also, the vertical direction is based on FIG.

  First, the male connector housing 11 will be described with reference to FIGS. The male connector housing 11 is made of synthetic resin, and a hood portion 12 capable of accommodating the female connector housing 30 is provided at the front portion in a state of opening toward the front side. On the outer surface of the hood portion 12, an overhanging piece 13 is formed over the entire circumference in the vicinity of the center in the front-rear direction. Inside the hood portion 12, a plurality of male terminal fittings 14 formed in a tab piece shape are mounted on the back wall of the hood portion 12. One end side of each male terminal fitting 14 protrudes from the back surface of the male connector housing 11 and is bent downward, and the tip end side is connected to the circuit board 15. The other end side of each male terminal fitting 14 protrudes into the hood portion 12. On the inner side wall of the upper wall of the hood portion 12, a lock projection 16 that engages with a lock arm 43 (described later) protrudes downward at the front end edge and near the center in the lateral width direction.

Next, the female connector housing 30 will be described with reference to FIGS. 1 and 5. A female-side terminal fitting 31 is accommodated in the female-side connector housing 30, and the female-side terminal fitting 31 is double-locked in a retaining state by a retainer 32.
The female terminal fitting 31 is formed by pressing a metal plate. On the front end side of the female terminal fitting 31, there is provided a rectangular tubular connecting portion 33 that can come into contact with the mating male terminal fitting 14. A barrel portion 34 to which the end of the electric wire W is fixed is provided on the rear end side. An electric wire W is caulked to the barrel portion 34. A locking projection 35 that locks a lance 41 (described later) protrudes from the bottom surface of the connecting portion 33.

  The female connector housing 30 is made of synthetic resin. The female connector housing 30 includes a female housing main body 36 formed in a substantially rectangular parallelepiped shape, and a short-circuit terminal accommodating portion 37 formed so as to protrude upward from the vicinity of the center in the lateral width direction on the upper wall of the female housing main body 36. It consists of.

  A plurality of cavities 38 that can accommodate the female terminal fittings 31 are formed in the female housing main body 36. Each cavity 38 is opened in the front-rear direction of the main body. Among these, the rear side is greatly opened as a terminal mounting opening 39, while the front side is opened small as a terminal insertion opening 40. A tapered slope for guiding the male terminal fitting 14 is formed at the hole edge on the surface side of the terminal insertion port 40. A lance 41 is integrally formed on the bottom surface of each cavity 38. The lance 41 is formed so as to extend forward in a cantilever manner, and is formed so as to be able to be locked to the locking protrusion 35 of the female terminal fitting 31. At the center in the front-rear direction on the lower surface of the female-side housing body 36, a retainer mounting port 42 communicating with each cavity 38 is opened, and the retainer 32 is assembled to the retainer mounting port 42.

  The retainer 32 can be held at the temporary locking position and the main locking position with respect to the female-side housing body 36. When the retainer 32 is held in the temporary locking position, the female terminal fitting 31 can be inserted into and removed from the terminal mounting port 39 in the cavity 38. On the other hand, when the retainer 32 is held at the final locking position, the female terminal fitting 31 is double-stopped inside each cavity 38 by the retainer 32 and the lance 41.

  Note that two of the cavities 38 at the uppermost stage on both the left and right sides in FIG. 5 are short-circuit piece accommodation chambers (not shown) for accommodating short-circuit pieces (not shown) inside, and each short-circuit piece is below. The female terminal fittings 31 in the two adjacent cavities 38 are short-circuited.

  The short-circuit terminal accommodating portion 37 is disposed so as to be sandwiched between the above-described short-circuit piece accommodating chambers, and extends substantially over the entire length along the front-rear direction of the female-side housing body 36. A lock arm 43 is provided at the upper end of the short-circuit terminal accommodating portion 37. On the left and right sides of the lock arm 43, a pair of rib pieces 44, 44 for protecting the lock arm 43 project upward from the short-circuit terminal accommodating portion 37.

  The lock arm 43 is formed in a cantilever shape in which the front end side is connected to the front wall 49 of the short-circuit terminal accommodating portion 37 and the connecting portion serves as a fulcrum portion 45 while the rear end side is a free end. The lock arm 43 can be bent and deformed in the vertical direction. When the lock protrusion 46 protruding on the upper surface side is engaged with the lock protrusion 16, both the connector housings 11 and 30 are prevented from coming off. . The lock protrusion 46 is formed to be divided into left and right parts so that a detection terminal protection wall 18 described later does not interfere. The upper surface of the rear end of the lock arm 43 is a pressing operation unit 47. When releasing the fitting state of both the connector housings 11 and 30, the lock arm 43 is bent and deformed by pressing the pressing operation portion 47, and the lock projection 46 and the lock projection 16 are locked and released. Can do.

  The front wall 49 is opened with a window 50 through which the detection terminal protection wall 18 of the female connector housing 30 described later in the male and female connector housings 11 and 30 is inserted. This window 50 corresponds to the fulcrum portion 45 of the lock arm 43, and continues to the accommodation groove 48 that is cut out to reach the central portion in the length direction of the lock arm 43.

  A short-circuit terminal 51 is attached to the short-circuit terminal accommodating portion 37 below the lock arm 43. The short-circuit terminal 51 is for detecting whether or not the male and female connector housings 11 and 30 are properly fitted, and is formed by bending a metal plate, so that the connector housings 11 and 30 are properly fitted. When this is done, it is possible to make contact with a pair of detection terminals 17, 17 described later. For this reason, although not shown in detail, the short-circuit terminal 51 has a pair of left and right elastic contact pieces 52, which can be bent in the vertical direction, and in the middle, a contact protrusion 54 that can contact the detection terminal 17. (Corresponding to the contact portion) is projected. The tip edge of the short-circuit terminal 51 is a push-in portion 55 having a thickness of two sheets by bending the plate material. The short circuit terminal 51 is fixed. Furthermore, the rear portion of the elastic contact piece has a substantially triangular side cross section, and the uppermost end portion is a pressing portion 53.

  When the female connector housing 30 is a single unit, the upper end of the pressing portion 53 faces just below the lock arm 43 with a slight clearance. During the fitting of the male and female connector housings 11, 30, the lock projection 46 provided on the lock arm 43 and the lock projection 16 of the male connector housing 11 come into contact with each other, and the lock arm 43 bends downward. Deforms (see FIG. 7). At this time, the elastic contact piece 52 of the short-circuit terminal 17 disposed below the lock arm 43 is bent and deformed when the pressing portion 53 is pressed downward. At this time, since the contact protrusion 54 is positioned below the detection terminal 17, contact with the detection terminal 17 is avoided. For this reason, a short circuit (not shown) is not formed, and it is not recognized that both connector housings 11 and 30 are in a properly fitted state.

  When the fitting of both the connector housings 11 and 30 further proceeds, the lock projection 46 gets over the lock projection 16 and the contact between both is released, and the lock arm 43 is restored and deformed. Then, since the pressing force to the pressing portion 53 is lost, the elastic contact piece 52 is restored and deformed, and the contact protrusion 54 and the detection terminal 17 can come into contact (see FIG. 8). Thus, the contact between the detection terminal 17 and the short-circuit terminal 51 secures the conduction of the detection circuit (not shown) connected to the detection terminal 17 and the connector housings 11 and 30 are brought into the normal fitting state. It is judged.

  A pair of guide ribs 57 and 57 are formed on the left and right side edges of the upper wall of the female housing body 36. In FIG. 5, the lateral width of the guide rib 57 positioned on the left side is wider than that of the guide rib 57 positioned on the right side. The guide rib 57 guides the push-in direction of both the connector housings 11 and 30 by entering along the guide groove 20 of the male connector housing 11 described later.

  Now, in the hood portion 12 of the male connector housing 11, a pair of left and right detection terminals 17 formed in the shape of a tab piece near the center in the width direction of the hood portion 12 above each male terminal fitting 14. , 17 are attached to the back wall of the hood section 12. Similar to the male terminal fitting 14, one end side of each of the detection terminals 17, 17 protrudes from the back surface of the male connector housing 11 and is bent downward, and the tip side is connected to the circuit board 15. The detection terminal 17 is connected to a detection circuit (not shown), and when the detection terminal 17 is short-circuited, the detection circuit can detect that the connector housings 11 and 30 are properly fitted. Further, the other end side of each detection terminal 17, 17 protrudes into the hood portion 12. The protruding lengths of the detection terminals 17 and 17 into the hood portion 12 are longer than the protruding lengths of the male terminal fittings 14, and an appropriate bending in the vertical direction is allowed.

  A detection terminal protection unit 18 is formed between the left and right detection terminals 17 and 17. The detection terminal protection wall 18 is formed to hang from the inner wall of the upper wall of the hood portion 12, and the lower end thereof is formed at a height position slightly below the detection terminal 17. The width of the detection terminal protection wall 18 is such that the lower end portion (substantially the same height position as the detection terminal) is formed to be slightly wider so that it can enter the receiving groove 48 of the lock arm 43 through the window 50. Is formed.

  The upper part of the detection terminal protection wall 18 is continuous with the lock protrusion 16. In the region below the lock protrusion 16 and above the detection terminal 17, the front end of the detection terminal protection wall 18 is slightly retracted from the front end edge of the hood portion 12. At the substantially same height position as the detection terminal 17, the front end of the detection terminal protection wall 18 is formed in a state protruding forward from the front end of the detection terminal 17.

  On the inner wall surface of the upper wall of the hood portion 12, a pair of left and right kink preventing ribs 19 are provided so as to protrude downward from the left and right corners of the hood portion 12 in FIG. The front end of the kink preventing rib 19 is formed flush with the front end of the hood portion 12, extends along the front-rear direction, and reaches the back wall of the hood portion 12.

  In FIG. 2, the lower end of the left-hand kink preventing rib 19 is in a state in which approximately two-thirds from the left end is recessed above the approximately one-third from the right end. Thereby, the guide groove 20 is formed. A portion of about one third from the right end is formed at the same height as the lower end of the detection terminal protection wall 18.

  In FIG. 2, the lower end of the right-hand kink preventing rib 19 is in a state in which a portion of about one third from the right end is recessed above a portion of about two thirds from the left end. Thereby, the guide groove 20 is formed. The approximately two-thirds portion from the left end is formed at the same height as the lower end of the detection terminal protection wall 18.

  Each guide groove 20 described above is formed in a dimension that allows each guide rib 57 of the female housing body to enter.

  The female connector housing 30 is formed with a detection terminal insertion space 62 in which the detection terminal 17 can be accommodated. The detection terminal insertion space 62 is open to the front, and opens as detection terminal insertion openings 63 on the left and right sides of the lower end of the window 50 in the front wall 49 of the female connector housing 30. The detection terminal insertion port 63 and the window 50 communicate with each other in the left-right direction.

  The front portion of the detection terminal insertion space 62 is formed so as to expand in the vertical direction from the back to the front, and serves as a guide portion 66 for guiding the detection terminal 17.

  On the other hand, the height of the rear portion of the detection terminal insertion space 62 is equal to the thickness of the detection terminal 17, and the detection terminal 17 is inserted when both the connector housings 11 and 30 are fitted and the detection terminal 17 is inserted. The height defining portion 67 is set to a height position at which the short-circuit terminal 51 comes into contact with the preset height position.

  The lower wall of the detection terminal insertion space 62 is a first detection terminal restricting portion 59 (corresponding to positioning means) that restricts the downward displacement of the detection terminal 17. On the other hand, the upper wall of the detection terminal insertion space 62 is a second detection terminal restricting portion 61 (corresponding to a positioning means) that restricts the upward displacement of the detection terminal 17. A leading surface 64 is formed in front of the first and second detection terminal restricting portions 59 and 61, and a guiding portion 66 is formed by the leading surface 64. In addition, a height defining surface 65 is formed at the rear of the first and second detection terminal restricting portions 59 and 61, and a height defining portion 67 is formed by the height defining surface 65.

  The second detection terminal restricting portion 61 is formed to extend deeper than the first detection terminal restricting portion 59. Thereby, when both the connector housings 11 and 30 are fitted, the height defining surface 65 of the second detection terminal restricting portion 61 contacts the detection terminal 17 from above and the contact protrusion 54 of the short-circuit terminal 51. However, it can come into contact with the detection terminal 17 from below.

  Next, operations and effects of the present embodiment will be described with reference to FIGS. First, referring to FIGS. 6 to 8, a state when the connector housings 11 and 30 are fitted together will be described.

  The male and female connector housings 11 and 30 are opposed to each other with their front sides facing each other (see also FIG. 1), and the female connector housing 30 is inserted into the hood portion 12 of the male connector housing 11. Then, the fitting operation is started.

  During the fitting of the male and female connector housings 11 and 30, the lock projection 46 and the lock projection 16 come into contact with each other, and the lock arm 43 is bent and deformed downward (see FIG. 7). The pressing portion 53 disposed below the lock arm 43 is pressed, and the elastic contact piece 52 is bent downward and deformed. Then, as a result of the contact protrusion 54 being positioned below the detection terminal 17, contact between the detection terminal 17 and the short-circuit terminal 51 is avoided.

  When the fitting of both the connector housings 11 and 30 further proceeds, the lock projection 46 gets over the lock projection 16 and the contact between both is released, and the lock arm 43 is restored and deformed. Then, since the pressing force to the pressing portion 53 is lost, the elastic contact piece 52 is restored and deformed, and the contact protrusion 54 and the detection terminal 17 can come into contact (see FIG. 8). Thus, the contact between the detection terminal 17 and the short-circuit terminal 51 ensures the conduction of the detection circuit (not shown) connected to the detection terminal 17, and both the connector housings 11, 30 have reached the normal fitting state. It is judged.

  Now, since the front end portions of the first and second detection terminal restricting portions 59 and 61 are formed with a guide surface 64 for drawing the detection terminal 17, the detection terminal 17 is inserted into the detection terminal insertion port 63. Even when the detection terminal 17 is in a state of being misaligned in the vertical direction (see FIG. 6), the detection terminal 17 is corrected in the vertical direction by the guide surface 64 formed in the detection terminal insertion port 63. However, it is guided to the detection terminal insertion space 62 from the direction of the arrow in FIG.

  When the connector housings 11 and 30 are further fitted, the detection terminal 17 is sandwiched from above and below by the height defining surfaces 65 of the first and second detection terminal restricting portions 59 and 61 (FIG. 7). , 8). Thereby, the detection terminal 17 is hold | maintained in a regular height position. Thus, the detection terminal 17 can be positioned at the normal height position by the first and second detection terminal restricting portions 59 and 61. Since the first and second detection terminal restricting portions 59 and 61 are formed in the female connector housing 30, only the female connector housing 30 can be inspected by performing a dimensional inspection. It is simple.

  Next, the operation of the detection terminal protection wall 18 and the kink preventing rib 19 will be described with reference to FIGS. 9 and 10.

  In the present embodiment, the detection terminal protection wall 18 is formed between the detection terminals 17 and 17, and the front end portion of the detection terminal protection wall 18 is positioned in front of the detection terminal 17. As a result, when a large foreign object enters the hood portion 12 from the front, the foreign object hits the detection terminal protection wall 18, so that the foreign object can be prevented from interfering with the detection terminal 17 and the detection terminal 17 being deformed.

  Further, as shown in FIG. 9, when the female connector housing 30 is fitted to the male connector housing 11 in a state of being displaced by, for example, about 45 degrees about the vertical rotation axis, the female connector The outer wall portion of the housing 30 contacts the opening edge of the hood portion 12 from the front. Even when the female connector housing 30 is rotated in the state where both are in contact with each other, the female connector housing 30 comes into contact with the first kink preventing rib 19 from the front, and further enters the back. It is prevented. In the present embodiment, since the female connector housing 30 is also in contact with the detection terminal protection wall 18, it is prevented that the female connector housing 30 enters the back of the hood portion 12. Thereby, it is prevented that the female connector housing 30 interferes with the detection terminal 17 and the detection terminal 17 is deformed.

  As shown in FIG. 10, when the female connector housing 30 is fitted to the male connector housing 11 with the rotation axis in the horizontal width direction as a center, for example, shifted by about 45 degrees, the female connector housing 30 is The opening edge of the hood part 12 comes into contact with the front. Even when the female connector housing 30 is rotated in the state where both are in contact with each other, the female connector housing 30 is prevented from entering further into the back by contacting the kink preventing rib 19 from the front. Is done. Thereby, it is prevented that the female connector housing 30 interferes with the detection terminal 17 and the detection terminal 17 is deformed.

  In order to prevent the connectors from being twisted, the position where the twist preventing ribs 19 are provided and the length of protrusion downward may be appropriately designed.

The effects of this embodiment are summarized as follows.
(1) Since the positioning means (the first and second detection terminal restricting portions 59 and 61) of the detection terminal 17 is disposed only on the female connector housing 30, the dimension inspection is performed only on the female connector housing 30. Since it only has to be performed, the inspection process can be simplified.

  (2) Since the front end portions of the first and second detection terminal restricting portions 59 and 61 are formed with a lead-in surface 64 for drawing in the detection terminals, when the connector housings 11 and 30 are fitted together, The detection terminal 17 is smoothly guided to the normal height position.

  (3) Since the detection terminal protection wall 18 is formed in the hood portion 12, it is possible to prevent foreign objects from interfering with the detection terminal 17 and deformation of the detection terminal 17.

  (4) Since the kink preventing rib 19 is provided in the hood part 12, even if the female connector housing 30 enters the hood part 12 in an oblique posture, the detection terminal 17 is prevented from being deformed. .
