Description

  The present invention relates to a connector.

  Patent Document 1 discloses a connector in which a lock arm is formed along the outer surface of a connector housing. The lock arm is always held in the lock position, but can be elastically bent to a release position close to the outer surface of the connector housing. In the process of mating with the mating connector, the lock arm is elastically bent once to the release position, and when it is properly mated with the mating connector, the lock arm is elastically returned to the lock position and locked to the lock portion of the mating connector. Thus, both connectors are locked in the fitted state. Further, when releasing both connectors in the fitted state, the operator pushes the operation part of the lock arm with a finger so that the lock arm is elastically bent to the release position and the lock arm is detached from the lock part. It is like that.

JP 2004-39555 A

  In the above connector, since a bending space for allowing the elastic deformation of the lock arm is secured between the outer surface of the connector housing and the lock arm, the electric wire entering the bending space is pulled to the lock arm side. If it is done, there is a possibility that the lock arm may be reversed in an incorrect direction opposite to the release position side. Therefore, on the outer surface of the connector housing, there are formed restricting portions that restrict the reversing operation of the lock arm by contacting the side edge portions of the lock arm located on both the left and right sides of the lock arm.

  However, when there is a restriction in the width direction on the outer surface of the connector housing in order to arrange the restricting portion and the lock arm, the entire lock arm becomes narrow, and the operation portion becomes inevitably narrow. When the operation unit becomes narrow in this way, when the finger belly (the area where the fingerprint is located) is directed to the operation unit, both sides of the finger hit the regulation unit, and the operation unit may be pushed. There is a risk that it will not be possible. Such a problem is not limited to the case where a control part for preventing reversal is provided, but also when the operation part becomes narrow due to the formation of protective walls on both the left and right sides of the lock arm. This is a problem that can occur.

  The present invention has been completed based on the above situation, and an object of the present invention is to perform a pushing operation with a finger on an operation portion of a lock arm without any trouble.

As a means for achieving the above object, the invention of claim 1 extends along the outer surface of the connector housing from the connector housing and the bending fulcrum portion connected to the connector housing to the free end operation portion. A lock arm that is always in a locked position, but is elastically bent to a release position closer to the outer surface of the connector housing than the lock position, and formed in the operation portion, An operation surface to which an operation force is applied by a finger during a push operation for displacing the lock arm to the release position side, and a pair of interference units arranged so as to sandwich the operation unit from both sides in the width direction. a connector comprising, wherein the operation portion, a pair of locking portions located as facing each other in a in a width direction in the raised form from the operation surface is formed and Serial two locking portion is a form extending continuously along the extending direction of the lock arm, also, the rear end surface of the operation portion is the place which is located offset rearward from the rear end of the interference portion It has the characteristics.

According to a second aspect of the present invention, in the first aspect, the connector housing is formed by a mold that is opened along the extending direction of the lock arm. The recess formed between the locking portions is characterized in that at least one of the ends in the extending direction of the lock arm is open .

<Invention of Claim 1>
In general, since the thickness dimension of a human finger is smaller than the width dimension, when pressing the operation unit, the tip of the nail should be pressed against the operation unit so that the belly of the finger faces the width direction. The finger can be prevented from interfering with the interference part. When the operation unit is pushed so that the finger does not interfere with the interference unit in this way, the bending direction of the finger joint is the width direction substantially perpendicular to the direction in which the operation unit is pushed. There is a concern that the finger may shift in the width direction above. However, since a pair of engaging portions facing each other in the width direction are provided on the operation surface, the finger can be prevented from shifting in the width direction by catching the nail or the fingertip on the engaging portions. Thereby, pushing operation with a finger can be performed without hindrance.
Further, since the locking portion has a locking surface extending in the extending direction of the lock arm, that is, the direction intersecting the width direction of the lock arm, the finger is extended when the operation surface is pushed. Even if it deviates in the outward direction, the finger is kept locked in the locking portion.

<Invention of Claim 2>
Since the recess between the pair of locking portions has a shape in which at least one of the ends in the extending direction of the lock arm is open, the lock arm is extended from the lock arm. It is possible to mold using only a mold that opens in the direction. This means that the lock arm and the connector housing can be molded with a common mold, so that the mold cost can be reduced.

<Embodiment 1>
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The connector A of the present embodiment is made of synthetic resin, and includes a connector housing 10 having a block shape as a whole, and a lock arm 16 extending in the front-rear direction along the outer surface (upper surface) of the connector housing 10. It is molded integrally using a mold (not shown) that opens in the direction. The front-rear direction is a direction parallel to a fitting / removing direction with a mating connector (not shown).

  In the connector housing 10, a plurality of cavities 11, which are spaces for inserting terminal fittings (not shown), are formed in two upper and lower stages. Since the cavity 11 is configured to penetrate the connector housing 10 in the front-rear direction, the cavity 11 is molded by the above-described mold that is opened in the front-rear direction.

  The connector housing 10 is formed with an accommodating space 12 having a shape in which the upper surface is partially recessed. The housing space 12 is open to the upper surface, the front end surface, and the rear end surface of the connector housing 10, in other words, has a shape that penetrates in the front-rear direction. Therefore, the accommodation space 12 is also molded by the above-described mold that is opened in the front-rear direction.

  On the upper surface of the connector housing 10, a wall portion 13 that is elongated in the front-rear direction along the left and right edges of the opening on the upper surface side of the housing space 12 and extends in a rib shape is a virtual axis ( A pair is formed symmetrically with respect to (not shown). The range in which the wall portion 13 is formed in the front-rear direction is a region of about 1/3 on the rear end side of the housing space 12 (connector housing 10).

  Interference portions 14 projecting inward are formed symmetrically on the inner side surfaces (surfaces facing each other in the width direction) of the left and right wall portions 13. The pair of interference portions 14 are elongated in the front-rear direction and extend in a rib shape. The upper surface of the interference portion 14 is continuous with the upper surface of the wall portion 13. Moreover, the formation range of the interference part 14 in the front-back direction is a region of about 1/3 of the wall part 13 on the front end side. That is, the front end surface of the interference portion 14 is continuous with the front end surface of the wall portion 13. In addition, a pair of symmetrically tapered surfaces inclined so that the interval in the width direction gradually increases upward in the rear end region where the interference portion 14 is not formed on the inner side surfaces of the left and right wall portions 13. 15 is formed.

  A lock arm 16 is disposed in the accommodation space 12. The lock arm 16 includes a main body portion 17 that is elongated in the front-rear direction as a whole, a bending fulcrum portion 18 formed at the front end portion of the main body portion 17, and an operation portion 20 formed at the rear end portion of the main body portion 17. Configured. A lock protrusion 19 that protrudes upward (on the opposite side to the connector housing 10) is formed at a substantially central position in the front-rear direction of the main body portion 17. The bending fulcrum portion 18 is connected to the front end portion of the bottom surface 12S of the housing space 12 (the outer surface of the connector housing 10 which is a constituent element of the present invention), and the lock arm 16 is located behind the bending fulcrum portion 18 (the operation portion 20). It is the form extended to the cantilever shape along the bottom face 12S of the accommodation space 12 until it reached the side). Therefore, the operation unit 20 is disposed at the free end of the lock arm 16.

  The lock arm 16 is always held at the lock position (see FIGS. 2, 3, 4 and 6), but the lock arm 16 is released closer to the bottom surface 12S of the accommodating space 12 than the lock position with the bending fulcrum 18 as a fulcrum. It can be elastically bent to a position (see FIG. 1). In the state of being in the locked position, the main body portion 17 is substantially parallel to the bottom surface 12S of the accommodation space 12, but in the state of being displaced to the release position, the main body portion 17 is inclined downward with respect to the bottom surface 12S of the accommodation space 12. (The rear end side approaches the bottom surface 12S of the accommodation space 12) so as to be inclined. Further, when the lock arm 16 is elastically deformed, the operation unit 20 is displaced substantially integrally with the main body unit 17.

  In the process in which the connector A and the mating connector of the present embodiment are fitted, the lock projections 19 interfere with the lock portion (not shown) of the mating connector, so that the lock arm 16 is elastically bent to the release position. When the connector A and the mating connector reach the proper mating state, the lock arm 16 is elastically restored and the lock protrusion 19 is locked to the lock portion. Locked to the mated state.

  Further, when the connector A and the mating connector are separated from each other, the lock arm 16 is elastically bent from the lock position to the release position by pressing the operation unit 20 with the finger F as described later. The connector A and the mating connector may be pulled apart while maintaining this state.

  The operation unit 20 has a thickness dimension larger than that of the main body unit 17 as a whole, and the outer shape is block-shaped. The lower surface of the operation unit 20 (the surface facing the outer surface of the connector housing 10) and the left and right outer surfaces are connected to the lower surface of the main body 17 and the left and right outer surfaces, respectively. Is higher than the upper surface of the main body 17 in a stepped shape. The front end surface of the operation unit 20 is substantially in the same position as the front end surface of the wall 13 in the front-rear direction, and the rear end surface of the operation unit 20 (the rear end surface of the lock arm 16) is in front of the rear end of the wall 13. Therefore, it is located behind the rear end of the interference part 14.

  A punching hole 21 is formed in the operation unit 20 so as to penetrate in the front-rear direction. On the projection surface (not shown) in the front-rear direction, the punching hole 21 has a shape and a size surrounding the lock projection 19. By forming the punching hole 21, the operation unit 20 is formed of a top plate 22, left and right side plates 23, and a bottom plate 24 and has a box shape penetrating in the front-rear direction. And by forming the die-cutting hole 21, the main body 17 and the operation part 20 of the lock arm 16 can be molded by the above-described mold that is opened in the front-rear direction.

  The entire surface of the outer surface (upper surface) of the upper surface plate 22 forming the square of the operation unit 20 is an operation surface 25. When the operator performs a downward pressing operation to displace the lock arm 16 from the lock position to the release position using the finger F, the finger F is pressed or the tip of the finger F approaches. The surface, that is, the surface to which the operation force by the finger F is applied. In a state where the lock arm 16 is held in the locked position, the operation surface 25 is slightly higher than a region of the upper surface of the connector housing 10 where the accommodation space 12 is not formed, and is slightly lower than the upper surface of the interference portion 14. In position. In a state where the lock arm 16 is displaced to the release position, the operation surface 25 is at a position lower than a region of the upper surface of the connector housing 10 where the accommodation space 12 is not formed.

  The operation surface 25 is formed with a pair of left and right engaging portions 26 that are symmetrical with respect to the virtual axis at the center in the width direction of the operation surface 25 (operation unit 20). The locking portion 26 protrudes upward from the operation surface 25 and has a form extending linearly continuously in the front-rear direction. The inner side surfaces (surfaces that face each other in the width direction) of the pair of locking portions 26 are elongated in the front-rear direction (direction parallel to the extending direction of the lock arm 16) and are parallel to each other. 27. The locking surface 27 is perpendicular to the operation surface 25.

  A space above the operation surface 25 and sandwiched between the pair of locking portions 26 is a recess 28. The concave portion 28 has a form penetrating from the front end to the rear end of the operation unit 20, that is, a form in which both front and rear ends are open, and has a rectangular shape on a front and rear projection surface (not shown). As described above, since the locking portion 26, the locking surface 27, and the concave portion 28 formed on the operation surface 25 are all extended straight in the front-rear direction, the front-rear direction is the same as that of the connector housing 10. It is molded only by the above-described mold that is opened.

  The range in which the locking portion 26, the locking surface 27, and the recess 28 are formed in the front-rear direction is about a half of the rear end side of the operation portion 20 (operation surface 25). The front end surface of the locking portion 26 is positioned slightly forward of the rear end of the interference portion 14, and the rear end surface of the locking portion 26 is continuous with the rear end surface of the operation portion 20. That is, in the front-rear direction, the locking portion 26 is positioned within the range of the wall 13 forming region, and most of the locking portion 26 excluding the front end is within the range of the tapered surface 15 forming region. Is located. Further, in the state where the lock arm 16 is in the locked position, the upper surface of the locking portion 26 is substantially the same height as the upper surfaces of the wall portion 13 and the interference portion 14.

  The width dimension of one locking part 26 is about 1/3 of the entire width dimension of the operation part 20 (operation surface 25). Therefore, the width dimension of the recess 28 is also about 1/3 of the entire width dimension of the operation part 20. It is. That is, the locking part 26 and the recessed part 28 have substantially the same width dimension. The width dimension of the locking part 26 and the recessed part 28 is smaller than the length dimension before and after the locking part 26 and the recessed part 28, and the height dimension of the locking part 26 (that is, the depth dimension of the recessed part 28). Is smaller than the width dimension of the locking portion 26 and the recess 28.

  The outer surface of the locking portion 26 (the surface opposite to the locking surface 27) is continuous with the outer surface of the operation portion 20. In the width direction, the locking surface 27 is located within the formation range of the punching hole 21. That is, the width dimension of the concave portion 28 is smaller than the width dimension of the die punching hole 21, and the region on the locking surface 27 side (width direction center side) of the locking portion 26 is overlapped with the die cutting hole 21 in the width direction. Do (overlap). In other words, the left and right side edges are partially thickened and reinforced by the locking portions 26 in the approximately ½ region on the rear end side of the upper surface plate 22 of the operation portion 20.

  The operating unit 20 is formed with a pair of left and right protrusions 29 as means for preventing unauthorized deformation of the lock arm 16 in cooperation with the interference unit 14. The pair of protrusions 29 are symmetrical with respect to the central axis in the width direction of the operation unit 20 and protrude from the outer surface of the side plate 23. In the front-rear direction, the formation range of the protrusion 29 extends over substantially the same region as the formation range of the interference portion 14. That is, the front end of the protrusion 29 is at the same position as the front end of the operation unit 20. Further, the rear end of the protrusion 29 is located in front of the rear end of the operation unit 20 and slightly rearward of the front end of the locking part 26.

  The upper surface of the projection 29 is at a position lower than the operation surface 25, and the lower surface of the projection 29 is at a position higher than the lower surface of the operation unit 20. Further, in the state where the lock arm 16 is in the locked position, the upper surface of the protruding portion 29 is slightly lower than the lower surface of the interference portion 14. Therefore, when the lock arm 16 is displaced slightly above the lock position, the upper surface of the projection 29 comes into contact with the lower surface of the interference unit 14, so that further upward displacement of the lock arm 16 is restricted. Since the amount of upward displacement of the lock arm 16 at this time is within the range of the elastic limit of the lock arm 16, the lock arm 16 will not be plastically deformed illegally.

  Next, the operation of this embodiment will be described. The width dimension of the accommodating space 12 in which the lock arm 16 is accommodated, that is, the distance between the pair of left and right interference portions 14 is smaller than the width dimension of the finger F of an adult hand as shown in FIG. As shown in FIG. 1, in a state where the belly of the finger F is directed in the width direction (that is, in a state where the finger F is turned sideways), the dimensions are such that the tip portion of the finger F can be entered from above. ing. With this dimension setting, the height of the tip of the finger F when it is assumed that the finger F is placed sideways and inserted deepest into the accommodation space 12 is the operating surface 25 when the lock arm 16 is bent to the release position. The position will be the same as or lower than the height of.

  Therefore, when the operation unit 20 is pushed with the finger F so as to displace the lock arm 16 to the release position, the width direction of the finger F and the width direction of the connector A are in the same direction, and the finger F When the front end side portion of the operation unit 20 is pushed, the left and right side surfaces of the finger F hit the interference unit 14 before the lock arm 16 reaches the release position, and the finger F cannot be further inserted into the accommodation space 12. That is, the pushing operation of the lock arm 16 cannot be further advanced.

  Also, when the rear end portion of the operation unit 20 is pushed with the finger F so that the width direction of the finger F and the width direction of the connector A are in the same direction as described above, as shown in FIG. Before the lock arm 16 reaches the release position, the left and right side surfaces of the finger F hit the tapered surface 15 of the wall portion 13, and the finger F cannot be inserted into the receiving space 12 any more. That is, also in this case, the lock arm 16 cannot be bent to the release position.

  2 shows a state in which the operation portion 20 is pushed and operated with the tip of the finger F with the belly of the finger F facing forward, the operation unit with the belly of the finger F with the tip of the finger F facing forward. Even when pressing 20 is performed, the side edge portion of the finger F hits the interference portion 14 or the tapered surface 15 during the pressing operation, so that the lock arm 16 cannot be bent to the release position.

  Here, if attention is paid to the shape feature of the finger F that the thickness dimension of the finger F is smaller than the width dimension, and especially the thickness dimension becomes smaller toward the tip of the finger F, as shown in FIG. When the finger F faces sideways, the belly of the finger F faces one interference part 14 (that is, faces in the width direction), and the fingernail of the finger F faces the other interference part 14, the tip of the finger F Can be inserted deeply into the accommodation space 12 without hitting the interference portion 14 or the tapered surface 15 (that is, without being disturbed by the interference portion 14). Therefore, if the operation unit 20 is pushed from above with the tip of the finger F or the tip of the nail, the lock arm 16 can be reliably elastically bent to a predetermined release position.

  In particular, in the present embodiment, about a half of the rear end side of the operation unit 20 is located behind the interference unit 14, so the finger F is operated in a region behind the interference unit 14. If it is made to touch the part 20, it can avoid reliably that the finger F hits the interference part 14. FIG. Further, above the opening at the upper end of the accommodation space 12, the wall portion 13 that forms the interference portion 14 is inclined rearwardly of the interference portion 14 so as to increase the interval in the width direction upward. A pair of tapered surfaces 15 are formed. Therefore, if the finger F is used to aim at about a half of the operation surface 25 on the rear end side, not only can the interference with the interference portion 14 be avoided more reliably, but the finger F And the wall portion 13 can be avoided, and improvement in workability of the push operation can be expected.

  When the operation part 20 is pushed and operated with the tip of the finger F so that the belly and nails of the finger F face the width direction, as shown in FIG. Since the width direction is substantially perpendicular to the direction in which the portion 20 is pressed, there is a concern that the finger F slips on the operation surface 25 during the pressing operation and shifts in the width direction, thereby reducing workability. In particular, when the tip of the nail hits the operation surface 25, the nail is slippery as compared to the belly of the finger F, so that it is considered that the shifting operation of the finger F in the width direction becomes remarkable.

  However, in the present embodiment, since a pair of engaging portions 26 facing each other in the width direction are provided on the operation surface 25, the tip of the finger F is fitted in the recess 28 between the engaging portions 26. If it inserts, it can avoid that the front-end | tip of the finger | toe F or the tip of a nail | claw is caught by the latching | locking part 26, and the finger | toe F shifts | deviates to the width direction. Thereby, pushing operation with the finger | toe F can be performed without trouble.

  Further, since the pair of locking portions 26 are linearly extended in the extending direction of the lock arm 16, that is, the direction intersecting the width direction of the lock arm 16, when the operation portion 20 is pushed, Even if the finger F is displaced in the extending direction (front-rear direction) of the lock arm 16, the finger F is kept in a state of being locked to the locking portion 26.

  The connector housing 10 is molded by a mold that is opened along the extending direction of the lock arm 16, but a recess 28 formed between the pair of locking portions 26. The front and rear ends in the extending direction of the lock arm 16 are open. Therefore, the lock arm 16 can be molded using only a mold that is opened in the extending direction (front-rear direction) of the lock arm 16. This means that the lock arm 16 and the connector housing 10 can be molded with a common mold, so that the mold cost can be reduced.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIG. In the connector B of the second embodiment, the locking portion 30 is different from the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  A pair of symmetrical locking portions 30 formed on the operation surface 25 are configured to extend linearly in the front-rear direction continuously from the front end to the rear end of the operation surface 25. Further, the inner side surfaces (surfaces facing each other in the width direction) of the pair of locking portions 30 are planar locking surfaces 31 that extend in the front-rear direction and are parallel to each other over the entire length. That is, the locking portion 30 and the locking surface 31 of the second embodiment are formed over a longer range than the locking portion 26 and the locking surface 27 of the first embodiment.

  In addition, the recess 32 sandwiched between the pair of locking portions 30 is also formed in a range from the front end to the rear end of the operation surface 25, similarly to the locking portion 30 and the locking surface 31. Since the recess 32 has a configuration in which both front and rear ends in the extending direction of the lock arm 16 are opened, the lock arm 16 is opened in the extending direction of the lock arm 16 as in the first embodiment. It is possible to mold using only a mold (not shown).

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIG. The connector C of the third embodiment also has a locking portion different from that of the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  A pair of symmetrical locking portions 40 formed on the operation surface 25 extend linearly in the front-rear direction continuously from the front end to the rear end of the operation surface 25, similarly to the locking portion 30 of the second embodiment. It has a form. Similarly, the operation surface 25 has a rear edge side protrusion 41 that extends in the width direction along the rear edge of the operation surface 25 and protrudes in a rib shape so as to connect the rear ends of the pair of locking portions 40. Is formed. By forming the rear edge side protrusion 41 in this way, when the finger F is fitted into the recess 42 between the pair of locking portions 40 and the operation unit 20 is pushed, the finger F moves to the operation unit 20. On the other hand, there is no risk of slipping backward, and improvement in workability can be expected.

  Further, in the extending direction (front-rear direction) of the lock arm 16, the recess 42 is closed at the rear end by the rear edge side protrusion 41, whereas the front end is opened. As described above, since the recess 42 has a form in which at least one of the front and rear ends in the extending direction of the lock arm 16 is opened, the lock arm 16 extends the lock arm 16 as in the first embodiment. It is possible to mold using only a mold that is opened in the outgoing direction.

<Embodiment 4>
Next, a fourth embodiment of the present invention will be described with reference to FIG. In the connector D of the fourth embodiment, the locking portion is different from the first embodiment. Since other configurations are the same as those of the first embodiment, the same configurations are denoted by the same reference numerals, and descriptions of structures, operations, and effects are omitted.

  A pair of symmetrical locking portions 50 formed on the operation surface 25 are straight in the front-rear direction continuously from the front end to the rear end of the operation surface 25 as in the locking portions 30 and 40 of the second and third embodiments. It is the form extended in the shape. Similarly, the operation surface 25 extends in the width direction along the front edge of the operation surface 25 and protrudes in a rib shape so as to connect the front ends of the pair of locking portions 50, A rear edge protrusion 52 is formed that extends in the width direction along the rear edge of the surface 25 and protrudes in a rib shape so as to connect the rear ends of the pair of locking portions 50.

  Further, in the extending direction of the lock arm 16, the recess 53 between the pair of locking portions 50 has its front end closed by the front edge side protrusion 51 and its rear end closed by the rear edge side protrusion 52. ing. Thus, since the recessed part 53 has a form in which both front and rear ends in the extending direction of the lock arm 16 are closed, in order to form at least the recessed part 53 of the lock arm 16, the lock arm 16 In addition to the mold that opens in the extending direction, a mold (not shown) that opens in the direction (upward) intersecting the extending direction of the lock arm 16 is required.

  However, since the portions (the locking portion 50, the front edge side protrusion 51, and the rear edge side protrusion 52) that protrude in a rib shape along the front and rear end edges and the left and right end edges of the operation surface 25 are formed, the operation section 20 The rigidity is improved. Further, when the operation part 20 is pushed with the finger F, if the tip of the finger F is fitted into the recess 53, the finger F is not easily displaced in any of the front, rear, left and right directions. Improvement can be expected.
