Description

  The present invention relates to a connector with a retainer.

  As a conventional connector with a retainer, an opening is formed in the outer wall of a connector housing in which a cavity for accommodating a terminal fitting is formed, and the retainer is integrally formed so as to be rotatable through a hinge in the vicinity of the opening. is there. When the retainer is in the retracted position retracted from the cavity, the terminal fitting can be attached to and detached from the cavity. On the other hand, when the retainer is rotated to the entry position for entering the cavity, the retainer prevents the terminal fitting from coming off (see, for example, Patent Documents 1 to 3).

  The retainers of the connectors with these retainers are formed in the connector housing by hinges. For this reason, the retainer before being inserted into the opening is disposed at a substantially fixed position with respect to the connector housing. Therefore, an operator who inserts the retainer into the opening can easily insert the retainer into the opening by moving the retainer toward the opening of the connector housing.

  The operation of inserting the retainer into the opening is performed manually by various operators. Accordingly, the size of the operator's hand, the strength of the hand, the habit of operation, and the like vary depending on the operator. For this reason, depending on the magnitude and direction of the operator's force, the retainer may not be able to face the opening of the connector housing, which makes the work complicated and requires time to insert the retainer into the opening. The efficiency was decreasing.

<<< Connector Embodiment >>>
Embodiments will be described below with reference to the drawings. In this embodiment, a female connector is illustrated. The same applies to the male connector.

<<< Connector 10 >>>
Connector 10 includes a connector housing 100, a retainer 200, and a hinge 300. In the connector 10, the connector housing 100 and the retainer 200 are integrally formed of synthetic resin via the hinge 300. The retainer 200 can rotate with respect to the connector housing 100 via a hinge 300.

<< Connector housing 100 >>
The connector housing 100 is formed of a synthetic resin and has a substantially rectangular parallelepiped shape. As shown in FIGS. 1 to 4, the connector housing 100 has an upper surface 112 u and a lower surface 112 d, two side surfaces 110 a and 110 b, a terminal metal fitting insertion surface 114, and a terminal metal locking surface 116.

<Cavity 102>
As shown in FIG. 11, the terminal fitting 400 (see FIG. 5) is accommodated in the connector housing 100 along the direction in which the terminal fitting insertion surface 114 and the terminal fitting locking surface 116 of the connector housing 100 face each other. A cavity 102 is formed. The terminal fitting 400 is formed of metal, has conductivity, and has a long shape. Each of the cavities 102 is formed according to the shape and size of the terminal fitting 400 to be accommodated, and has a long shape.

  As shown in FIG. 5, in the connector housing 100, six cavities 102 are formed along the width direction (the direction in which the side surface 110a and the side surface 110b face each other) in each of the upper stage and the lower stage, and a total of 12 cavities are formed. A cavity 102 is formed.

<Lance 104>
As shown in FIG. 11, the terminal fitting 400 can be inserted from the terminal fitting insertion surface 114. A lance 104 is formed on each ceiling surface of the cavity 102. The lance 104 hooks the terminal fitting 400 as a first locking means so that the inserted terminal fitting 400 does not come out of the cavity 102.

<Retainer 200>
As shown in FIGS. 2, 4, and 11, the retainer 200 is integrally formed with the connector housing 100 on both the upper surface 112 u and the lower surface 112 d of the connector housing 100. The protrusion 206 (FIG. 3, FIG. 5, FIG. 15, etc.) of the retainer 200 locks the terminal fitting 400 as a second locking means so that the inserted terminal fitting 400 does not come out of the cavity 102. Details of the retainer 200 will be described later.

<Storage groove 106>
As shown in FIGS. 2 and 4, a housing groove 106 for inserting the retainer 200 is formed in the upper surface 112 u and the lower surface 112 d of the connector housing 100. In the storage groove 106, the cavity 102 is formed along a direction perpendicular to the longitudinal direction. The storage groove 106 is formed through the two side surfaces 110 a and 110 b of the cavity 102. The storage groove 106 has a long shape along the width direction of the connector housing 100. Therefore, the storage groove 106 formed on the upper surface 112u side is open to the upper surface 112u and the two side surfaces 110a and 110b. The storage groove 106 formed on the lower surface 112d side is open to the lower surface 112d and the two side surfaces 110a and 110b.

<Retainer locking projections 120a and 120b>
As shown in FIGS. 1, 2, 4, 5, 12, and 14, the connector housing 100 is formed with two retainer locking projections 120a and 120b protruding therefrom. The retainer locking projection 120a is formed on both the side surface 110a on the upper surface 112u side and the side surface 110a on the lower surface 112d. The retainer locking projection 120b is formed on both the side surface 110b on the upper surface 112u side and the side surface 110b on the lower surface 112d. As will be described later, the retainer locking projection 120a locks the side surface 202a of the retainer 200, and the retainer locking projection 120b locks the side surface 202b of the retainer 200.

  As shown in FIGS. 5, 12, and 14, the retainer locking protrusions 120 a and 120 b have a substantially square frustum shape. As four side surfaces of the retainer locking projections 120a and 120b, there are two tapered surfaces 122a and 122b and two locking surfaces 124a and 124b.

  The two tapered surfaces 122a and 122b are formed to be inclined with respect to the protruding direction of the retainer locking projections 120a and 120b. As shown in FIG. 12, when the retainer 200 is attached to the connector housing 100, the two side surfaces 202a and 202b can ride on the retainer locking projections 120a and 120b and slide smoothly.

  The two locking surfaces 124a and 124b are formed along the protruding direction of the retainer locking projections 120a and 120b. When the retainer 200 is attached to the connector housing 100, the two locking surfaces 124a and 124b can be engaged with the locking holes 220a and 220b, and the side surface 202a of the retainer 200 is locked by the retainer locking projection 120a. The side surface 202b of the retainer 200 can be locked by the retainer locking protrusion 120b. The engagement of the retainer locking protrusion 120a and the retainer locking protrusion 120b will be described later.

<Retainer locking protrusion 130>
As shown in FIG. 6, a retainer locking protrusion 130 is formed in the housing groove 106 of the connector housing 100 along the width direction of the connector housing 100. The retainer locking protrusion 130 has a long shape. The retainer locking protrusion 130 has an inclined first surface 132a, a second surface 132b that is erected, a third surface 132c that is erected, and a tip surface 134. The first surface 132 a, the second surface 132 b, the third surface 132 c, and the tip surface 134 have an elongated shape along the width direction of the connector housing 100.

  The second surface 132b and the third surface 132c are formed in parallel to each other. The width between the second surface 132b and the third surface 132c is slightly smaller than the width of the locking groove 230 (see FIGS. 3 and 9) (the length of the locking groove 230 in the short direction). Has been. Thereby, the retainer locking protrusion 130 can be inserted into the locking groove 230 and the retainer 200 can be locked.

  The 1st surface 132a inclines so that it may approach 2nd surface 132b, as it goes to the front end surface 134 of the retainer latching protrusion 130. As shown in FIG. The second surface 132 b is formed along the protruding direction of the retainer locking ridge 130. By forming the retainer locking ridge 130 in this way, the thickness of the retainer locking ridge 130 gradually decreases toward the distal end surface 134.

  In the process in which the retainer 200 is stored in the storage groove 106, the top surface 204 of the retainer 200 abuts on the first surface 132a. Since the first surface 132a is inclined so as to approach the second surface 132b, the top surface 204 rides on the retainer locking protrusion 130 and slides and moves on the first surface 132a. Can do.

  Further, when the retainer 200 is stored in the storage groove 106, the locking groove 230 can come into contact with the second surface 132b. Since the second surface 132b is formed flat, the locking groove 230 is latched by the second surface 132b, and the locking groove 230 is accurately locked by the retainer locking protrusion 130, and It is possible to prevent the stop groove 230 from separating from the retainer locking protrusion 130. The locking between the retainer locking protrusion 130 and the locking groove 230 will be described later.

<< Retainer 200 >>
As shown in FIGS. 2, 3, 4, and 9, the retainer 200 is formed of the same synthetic resin as the connector housing 100. The retainer 200 has two side surfaces 202a and 202b and a top surface 204 sandwiched between the two side surfaces 202a and 202b. Due to the two side surfaces 202a and 202b and the top surface 204, the retainer 200 has a substantially U-shaped cross section. The top surface 204 has a thin plate shape and a long shape, and the longitudinal direction of the top surface 204 is substantially perpendicular to the longitudinal direction of the cavity 102.

  When the retainer 200 is attached to the connector housing 100, the storage groove 106 can be covered by the two side surfaces 202 a and 202 b and the top surface 204. The side surface 202a covers the side surface 110a of the storage groove 106, the side surface 202b covers the side surface 110b of the storage groove 106, and the top surface 204 covers the upper surface 112u or the lower surface 112d of the storage groove 106.

<Protrusions 206>
As shown in FIGS. 3 and 5, six protrusions 206 are formed on the top surface 204. The six protrusions 206 are formed so as to protrude along a direction perpendicular to the longitudinal direction of the top surface 204.

  As described above, the retainer 200 locks the terminal fitting 400 as the second locking means. Specifically, when the retainer 200 is stored in the storage groove 106, each of the six protrusions 206 locks the terminal fitting 400 inserted into each of the cavities 102.

<Locking holes 220a and 220b>
As shown in FIG. 2, FIG. 4, FIG. 7, FIG. 10, etc., a locking hole 220a is formed on the side surface 202a, and a locking hole 220b is formed on the side surface 202b. As shown in FIG. 7, the locking holes 220a and 220b are through holes having a substantially rectangular opening 224. The locking holes 220a and 220b have four wall surfaces 222a, 222b, 222c, and 222d formed substantially perpendicular to the opening 224.

  A retainer locking projection 120a is inserted into the locking hole 220a to lock the side surface 202a of the retainer 200. A retainer locking projection 120b is inserted into the locking hole 220b to lock the side surface 202b of the retainer 200.

  As described above, it has two tapered surfaces 122a and 122b and two locking surfaces 124a and 124b. When the retainer locking projection 120a is inserted into the locking hole 220a, the two locking surfaces 124a and 124b are connected to the two wall surfaces 222c and 222d of the four wall surfaces 222a to 222d of the locking holes 220a and 220b. Can be engaged. Specifically, the locking surface 124a of the retainer locking projection 120a is in close contact with the wall surface 222d of the locking hole 220a, and the locking surface 124b of the retainer locking projection 120a is the wall surface of the locking hole 220a. Engage closely with 222c. As described above, the retainer 200 can be prevented from being detached from the connector housing 100 by the engagement between the locking surface of the retainer locking protrusion 120a and the wall surface of the locking hole 220a.

  The retainer 200 is connected to the connector housing 100 via a hinge 300. For this reason, it is assumed that the retainer 200 is applied with a force in a direction away from the connector housing 100 due to the restoring force of the hinge 300. Since the locking surface 124a of the retainer locking projection 120a is engaged with the wall surface 222d of the locking hole 220a and the locking surface 124b of the retainer locking projection 120a is engaged with the wall surface 222c of the locking hole 220a, The engaged state can be maintained opposite to the restoring force.

<Locking groove 230>
As shown in FIGS. 3, 9, 10, and the like, the top surface 204 of the retainer 200 is formed with a locking groove 230 having a long shape along the longitudinal direction of the retainer 200. As shown in FIG. 10, the locking groove 230 has two flat side walls 232a and 232b facing each other and a bottom portion 234 sandwiched between the two side walls 232a and 232b. The side walls 232a and 232b and the bottom portion 234 have a long and flat shape.

  When the retainer 200 is stored in the storage groove 106, the side wall 232 b of the locking groove 230 can come into contact with the second surface 132 b of the retainer locking protrusion 130. Since the side wall 232b of the retainer 200 and the second surface 132b of the retainer locking projection 130 are both long and flat, the side wall 232b of the locking groove 230 is in close contact with the second surface 132b. The locking groove 230 is latched and is accurately locked by the retainer locking protrusion 130, and the locking groove 230 can be prevented from being detached from the retainer locking protrusion 130.

  As described above, when the retainer 200 is stored in the storage groove 106, the retainer locking protrusion 130 is inserted into the locking groove 230 to lock the retainer 200 over the entire length of the retainer 200. And the retainer 200 can be stably held in the closed state.

<< Hinge 300 (Connector) >>
As shown in FIGS. 2 and 4, the retainer 200 is coupled to the connector housing 100 via a hinge 300. The hinge 300 is made of the same synthetic resin as the connector housing 100 and the retainer 200.

<Connecting portions 310a and 310b (first connecting portion) and connecting portion 320 (second connecting portion)>
As shown in FIGS. 7, 8, 10, etc., the hinge 300 includes two connecting portions 310 a and 310 b and a connecting portion 320. The connecting portions 310a and 310b have a predetermined constant thickness and have first flexibility. The connection part 310a has a linear shape. The connecting portion 310b has a shape curved at approximately 90 degrees.

  The connecting portion 320 has a groove shape having a curved concave surface in cross section, and has second flexibility. Since the connecting portion 320 has a curved concave groove shape, the connecting portion 320 has a thickness that is generally thinner than the connecting portions 310a and 310b.

  The connecting portions 310a and 310b have a predetermined constant thickness and have first flexibility. The connecting portion 320 has a thickness that is generally thinner than the connecting portions 310a and 310b, and has second flexibility. Thus, the difference between the first flexibility of the connecting portions 310a and 310b and the second flexibility of the connecting portion 320 is realized by the thickness. The first flexibility of the connecting portions 310a and 310b and the second flexibility of the connecting portion 320 can be determined as appropriate depending on the shape, size, material, and the like.

  An end portion of the coupling portion 310 a is connected to the connector housing 100. An end portion of the connecting portion 310b is connected to the retainer 200. The end portion of the connecting portion 310 a forms the first end portion of the hinge 300, and the end portion of the connecting portion 310 b forms the second end portion of the hinge 300.

  The connecting part 320 is formed between the two connecting parts 310a and 310b. The connecting part 320 is formed at the approximate center of the hinge 300. Preferably, the connecting portion 320 is closer to the retainer 200 than the connector housing 100 and is formed at a position deviated from the approximate center of the hinge 300.

  In the example described above, the connecting portion 320 has been shown to have a groove shape with a curved concave surface, but the cross section may have a substantially V-shape. Even when the cross section is substantially V-shaped, it is preferable that the valley bottom has a curved shape rather than a bent shape. By doing in this way, durability in the valley bottom of the connection part 320 can be improved.

  The connector 10 is preferably formed by a mold. When the connector 10 is molded by the mold, the connecting portion 310a having a linear shape, the connecting portion 310b having a shape curved at approximately 90 degrees, and the connecting portion having a groove-like shape having a curved concave surface. 320 is formed. Therefore, in a natural state before the retainer 200 is attached to the connector housing 100, the retainer 200 is in a position rotated by approximately 90 degrees with respect to the state in which the retainer 200 is attached to the connector housing 100. That is, as will be described later, the retainer 200 is attached to the connector housing 100 by rotating approximately 90 degrees. The retainer 200 can be positioned at a position rotated by approximately 90 degrees with respect to the state of being attached to the connector housing 100 by the connecting portion 310b having a shape curved at approximately 90 degrees.

<< Mounting of retainer 200 and deformation of hinge 300 >>
In general, the retainer 200 is attached by an operator's manual work in charge of the assembly process. In the process of attaching the retainer 200 to the connector housing 100, there are a rotation process (rotation activation) and a linear process (linear activation).

<Rotation process>
As shown in FIGS. 12 and 13, first, the operator applies a force to the retainer 200 so that the retainer 200 faces the storage groove 106. At this time, the retainer 200 moves while rotating around the hinge 300. The hinge 300 is deformed so as to be bent. As shown in FIG. 16, the hinge 300 is deformed so that the curved concave surface of the connecting portion 320 of the hinge 300 gradually expands and extends. Specifically, the hinge 300 is deformed so that the entire connecting portion 310b rotates while the curved concave surface of the connecting portion 320 gradually expands and extends around the bottom portion 330 of the connecting portion 320.

  FIG. 16 is a diagram showing a state of deformation of the two connecting portions 310 a and 310 b and the connecting portion 320 when the retainer 200 is gradually brought closer to the storage groove 106. FIG. 16A is a diagram illustrating a natural state in which no force is applied to the retainer 200. FIG. 16B to FIG. 16D are views showing a state when the retainer 200 is brought close to the storage groove 106.

  As shown in FIG. 16, the two connecting portions 310a and 310b are not deformed so much, and the hinge 300 is deformed when the connecting portion 320 is deformed. That is, the hinge 300 is deformed so that the curved concave surface of the connecting portion 320 of the hinge 300 gradually expands and extends. In this way, the hinge 300 is deformed around the bottom 330 of the connecting part 320, so that the bottom 330 of the connecting part 320 can be the center of rotation of the retainer 200. In this way, the bottom 330 of the connecting portion 320 can be set at a certain center, and the retainer 200 can be gradually rotated. For this reason, the retainer 200 can be moved along a fixed trajectory so that the retainer 200 is directed toward the storage groove 106 without depending on the magnitude, direction, or wrinkle of the operator's force.

  The operator can continue to apply force until the retainer 200 is brought into contact with the storage groove 106 and cannot move rotationally toward the storage groove 106. As shown in FIGS. 12 and 13, the retainer 200 can be rotated until the six protrusions 206 of the retainer 200 are restrained from moving by the wall surface 108 of the storage groove 106.

  In the final state of the rotational movement in which the retainer 200 abuts on the storage groove 106 and cannot rotate, the protrusion 206 of the retainer 200 that is the lowermost end of the retainer 200 reaches the position X shown in FIGS. At this position X, the protrusion 206 of the retainer 200 is not in contact with the terminal fitting 400 (not shown) accommodated in the cavity 102.

  By restricting the six protrusions 206 of the retainer 200 by the wall surface 108 of the storage groove 106, the six protrusions 206 face the terminal fitting 400 inserted into the cavity 102.

  As shown in FIG. 12, in the last stage (position X) of this rotation process, the retainer locking projection 120a is not inserted into the locking hole 220a, and the retainer locking projection 120b is inserted into the locking hole 220b. Not inserted. As shown in FIG. 12, the retainer locking projections 120a and 120b are in a state where the two side surfaces 202a and 202b ride on the retainer locking projections 120a and 120b.

<Linear process>
As shown in FIGS. 14 and 15, the operator then applies force to the retainer 200 toward the terminal fitting 400 (not shown) accommodated in the cavity 102. As a result, the retainer 200 moves linearly. The six protrusions 206 of the retainer 200 are in contact with the wall surface 108 of the storage groove 106, and the retainer 200 can be guided and linearly moved by the wall surface 108 of the storage groove 106.

  By moving the retainer 200 linearly, the six protrusions 206 of the retainer 200 press the terminal fitting 400, and when the retainer 200 is finally stored in the storage groove 106, the six protrusions 206 of the retainer 200 are moved to the terminal fitting. 400 is locked. In this way, the terminal fitting 400 inserted into the cavity 102 has two engagements between the lance 104 serving as the first locking means and the six protrusions 206 of the retainer 200 serving as the second locking means. The terminal fitting 400 can be accurately prevented from being pulled out of the cavity 102 by being locked by the stopping means. An electric wire is connected to the terminal fitting 400 to form an electrical connection. Even when force is applied to the electric wires inadvertently, the terminal fitting 400 can be prevented from being removed from the cavity 102, and electrical connection can be maintained.

  In the final state of linear movement in which the retainer 200 cannot move linearly, the six protrusions 206 of the retainer 200 lock the terminal fitting 400. The protrusion 206 of the retainer 200 that is the lowermost end of the retainer 200 reaches a position Y shown in FIGS.

  As shown in FIGS. 14 and 15, in the final stage (position Y) of this linear process, the retainer locking projection 120a is inserted into the locking hole 220a, and the side surface 202a of the retainer 200 is locked. Similarly, the retainer locking projection 120b is inserted into the locking hole 220b, and the side surface 202b of the retainer 200 is locked. Accordingly, the retainer 200 can be accurately locked to the two side surfaces 110 a and 110 b of the connector housing 100, and the retainer 200 can be prevented from being detached from the connector housing 100.

  Further, in the final stage of this linear process (position Y), the locking groove 230 is locked by the retainer locking ridge 130. As described above, the side wall 232 b of the retainer 200 is hooked by the second surface 132 b of the retainer locking protrusion 130. Since the side wall 232b of the retainer 200 and the second surface 132b of the retainer locking projection 130 are formed over the width direction of the connector housing 100, the retainer 200 is connected to the connector housing 100 over the entire width direction thereof. It can be locked to the housing 100.

  Thus, in the last stage of the straight line process (position Y), the retainer locking projection 120a is inserted into the locking hole 220a, and the retainer locking projection 120b is inserted into the locking hole 220b, whereby the side surface of the retainer 200 is obtained. The locked state of 202a and side 202b can be ensured. Furthermore, in the final stage of the linear process (position Y), the locking groove 230 is locked by the retainer locking ridge 130 so that the locked state in the longitudinal direction (width direction) of the retainer 200 can be ensured. it can. Thus, by securing two types of locking states, that is, the locking state of the side surface of the retainer 200 and the locking state in the longitudinal direction (width direction), the retainer 200 is accurately attached to the connector housing 100 and the cavity 102 is secured. The terminal fitting 400 inserted into the can is accurately locked by the six protrusions 206, and the locked state can be maintained.

  In the above-described embodiment, the female connector is exemplified, but the male connector can be similarly molded by a synthetic resin so that the retainer is connected to the connector housing via the hinge 300.
