Description

Locking structure, electrical connection box and wire harness
Technical Field
The invention relates to a lock structure, an electrical connection box, and a wire harness.
Background
Conventionally, a lock structure for holding 2 assembly members as an assembly target in an assembled state is known. The locking structure has: a locked body provided on one of the 2 assembly parts; and an engaging body provided on the other of the engaging bodies. When the 2 assembling components are assembled, the locking structure causes the engaged part of the engaged body and the engaging part of the engaging body to engage with each other, thereby holding the 2 assembling components in the assembled state. For example, the lock structure is applied to an electrical connection box that accommodates an object to be accommodated such as an electronic component or a module, an electrical connection box that accommodates an electric wire together with the object to be accommodated and constitutes a wire harness together with the electric wire that has been pulled out to the outside, and the like (patent documents 1 and 2 described below). In this electrical connection box, the housing object and the housing are assembled components, and a lock structure is applied to hold the housing object assembled by being housed in the housing in an assembled state. In this locking structure, a guided rail portion and a guide rail portion for guiding the engaged member along the engaging body until the engaged portion and the engaging portion reach the engagement completion position are provided. In this locking structure, the 2 guided rail portions of the engaged member are guided while being sandwiched by the 2 guide rail portions of the engaged member.

Disclosure of Invention
Technical problem to be solved by the invention
However, in the case of molding 2 pieces of assembly members from synthetic resin, the direction of pull-out from the mold is set so as to be along the assembly direction or the pull-out direction with respect to each other, and inclined surfaces having a slight inclination angle corresponding to the draft angle of the mold are formed on the wall surface, the end surface, or the like. Here, the engaged body and the engaged body are integrally formed with the assembly member. Therefore, in the engaged body and the engaging body, the direction of pulling out from the molding die is set to be along the extending direction of the guided rail portion and the guide rail portion (the guiding direction between each other), and the inclined surface having a minute inclination angle corresponding to the mold draft of the molding die is formed also on the wall surface of the guided rail portion and the guide rail portion. However, the inclined surface of the guided rail portion and the inclined surface of the guide rail portion are not necessarily disposed in parallel to each other in the sandwiching direction when the inclined surfaces are at the engagement completion position, and there is a possibility that a difference in the size of the gap may occur at each position between the inclined surfaces. For example, when the inclined surfaces are arranged to face each other in a state of being inclined in opposite directions, a difference occurs in the size of the gap at each position between the inclined surfaces. Even if the inclined surfaces are arranged to face each other in a state of being inclined in the same direction, if the inclination angles are different, the gap size at each position between the inclined surfaces differs. Therefore, in the conventional lock structure, even if the engagement between the engaged portion and the engaging portion is completed, there is a possibility that play may occur between the inclined surfaces of the guided rail portion and the guide rail portion. In addition, in the conventional lock structure, before the engagement between the engaged member and the engaging member is completed, the inclined surfaces of the guided rail portion and the guide rail portion abut against each other, and there is a possibility that the connection workability between the engaged member and the engaging member is deteriorated.
Accordingly, an object of the present invention is to provide a lock structure, an electrical connection box, and a wire harness, which can improve connection workability and suppress looseness.

One embodiment of a lock structure, an electrical connection box, and a wire harness according to the present invention will be described with reference to fig. 1 to 14.
Reference numeral 1 in fig. 1 to 8 denotes a lock structure of the present embodiment.
In order to maintain 2 assembling members (the 1 st assembling member 110 and the 2 nd assembling member 120) assembled with each other in a linear assembling operation in an assembled state, a lock structure 1 (fig. 1 and 8) is provided between the 1 st assembling member 110 and the 2 nd assembling member 120. Here, the 1 st assembling part 110 is accommodated and assembled inside with respect to the 2 nd assembling part 120 in a straight assembling operation. The lock structure 1 has: a fitted body 10 provided in one of the 1 st and 2 nd assembling parts 110 and 120; and a snap body 20 provided in the other one thereof (fig. 1 and 4 to 8).
The engaged body 10 and the engaging body 20 are formed to come into contact with each other as they approach each other in conjunction with the linear assembling operation of the 1 st assembling member 110 and the 2 nd assembling member 120, and are engaged with each other by completing the assembling of the 1 st assembling member 110 and the 2 nd assembling member 120. The engaged body 10 and the engaging body 20 are configured to maintain the engaged state with each other when the 1 st assembling member 110 and the 2 nd assembling member 120 are assembled, so as to maintain the 1 st assembling member 110 and the 2 nd assembling member 120 in the assembled state.
The engaged body 10 is molded integrally with one of the 1 st assembly member 110 and the 2 nd assembly member 120 by a 1 st molding die (not shown) using a synthetic resin material. The engaging body 20 is formed of a synthetic resin material by a 2 nd molding die (not shown) integrally with the other of the 1 st assembly member 110 and the 2 nd assembly member 120.
The engaged body 10 includes: an engaged portion 11; and a 1 st guided rail portion 12 and a 2 nd guided rail portion 13 which are disposed opposite to each other so that the engaged portion 11 is disposed between the two guided rail portions and extend along an assembling direction of the 1 st assembling member 110 and the 2 nd assembling member 120 and a pull-out direction from the 1 st molding die (fig. 1, 2, and 4 to 7). On the other hand, the engaging body 20 includes: an engaging portion 21 that engages with the engaged portion 11 when the 1 st assembly member 110 and the 2 nd assembly member 120 are assembled; and a 1 st guide rail portion 22 and a 2 nd guide rail portion 23 which are disposed so as to face each other so that the engaging portion 21 is disposed between the two guide rail portions and extend along the assembling direction of the 1 st assembling member 110 and the 2 nd assembling member 120 and the pull-out direction from the 2 nd molding die, the 1 st guide rail portion 22 and the 2 nd guide rail portion 23 guiding the 1 st guided rail portion 12 and the 2 nd guided rail portion 13 until the engaged portion 11 and the engaging portion 21 reach an engagement completion position, and sandwiching the 1 st guided rail portion 12 and the 2 nd guided rail portion 13 when the engaged portion 11 and the engaging portion 21 are at the engagement completion position (fig. 1 and 3 to 7).
For example, one of the engaged portion 11 and the engaging portion 21 may be a claw-shaped claw portion, and the other may be a wall portion to which the claw portion is engaged. For example, a peripheral wall portion such as a through hole, a groove, or a notch into which a claw portion enters when the 1 st assembly member 110 and the 2 nd assembly member 120 are assembled is used as the wall portion. The engaged portion 11 and the engaging portion 21 may be formed in a claw shape that can be engaged with each other when the 1 st assembly member 110 and the 2 nd assembly member 120 are assembled. Here, the engaged portion 11 and the engaging portion 21 are formed as claw portions, respectively (fig. 8).
The 1 st guided rail portion 12 has a guided wall surface 12A, and the guided wall surface 12A is disposed to face the 1 st guide rail portion 22 in the sandwiching direction between the 1 st guide rail portion 22 (fig. 1, 2, and 4 to 7). The 2 nd guided rail portion 13 has a guided wall surface 13A, and the guided wall surface 13A is disposed to face the 2 nd guide rail portion 23 in the sandwiching direction between the 2 nd guide rail portion 23 (fig. 1, 2, and 4 to 7). On the other hand, the 1 st guide rail portion 22 has a guide wall surface 22A, and the guide wall surface 22A guides the guided wall surface 12A of the 1 st guided rail portion 12 until the engaged portion 11 and the engaging portion 21 reach the engagement completion position, and the guide wall surface 22A is disposed to face the guided wall surface 12A of the 1 st guided rail portion 12 when the engaged portion 11 and the engaging portion 21 are at the engagement completion position (fig. 1 and 3 to 7). The guided wall surface 12A and the guide wall surface 22A are arranged to face each other in a sandwiching direction in which the 1 st guide rail portion 12 and the 2 nd guide rail portion 13 are sandwiched by the 1 st guide rail portion 22 and the 2 nd guide rail portion 23. The 2 nd guide rail portion 23 has a guide wall surface 23A that guides the guided wall surface 13A of the 2 nd guided rail portion 13 until the engaged portion 11 and the engaging portion 21 are at the engagement completion position, and the guide wall surface 23A is disposed so as to face the guided wall surface 13A of the 2 nd guided rail portion 13 when the engaged portion 11 and the engaging portion 21 are at the engagement completion position (fig. 1 and 3 to 7). The guided wall surface 13A and the guide wall surface 23A are disposed to face each other in a sandwiching direction in which the 1 st guide rail portion 12 and the 2 nd guide rail portion 13 are sandwiched by the 1 st guide rail portion 22 and the 2 nd guide rail portion 23.
The respective guided wall surfaces 12A, 13A are divided into a 1 st guided region T1 and a 2 nd guided region T2 (fig. 5 and 7) in the assembling direction of the 1 st assembling member 110 and the 2 nd assembling member 120, respectively. In the guided wall surface 12A, the side where the guidance by the guide wall surface 22A starts (in other words, the side where the insertion starts when the 1 st guided rail portion 12 is inserted into the 1 st guide rail portion 22) is set as the 2 nd guided region T2, and the opposite side is set as the 1 st guided region T1. In the guided wall surface 13A, the side where the guidance by the guide wall surface 23A starts (in other words, the side where the insertion starts when the 2 nd guided rail portion 13 is inserted into the 2 nd guided rail portion 23) is set as the 2 nd guided region T2, and the opposite side is set as the 1 st guided region T1. The guided wall surfaces 12A and 13A are formed so that the size of the 1 st guided region T1 in the assembling direction is equal and the size of the 2 nd guided region T2 in the assembling direction is equal.
Each of the guided wall surfaces 12A and 13A includes: 1 st guided portion 12A of 1 st guided region T11、13A1Inclined at an inclination angle of a draft angle of the 1 st forming die; and 2 nd guided part 12A2、13A2The guided region T2 is more inclined than the inclination angle of the draft angle of the 1 st forming die in the 2 nd region (fig. 2 and fig. 4 to 7). Here, the inclination angle of the draft of the 1 st molding die is a slight inclination angle slightly inclined from the 1 st molding die pulling-out direction, and is a known angle generally set in consideration of the degree of easy pulling-out of a molded article when molding a synthetic resin material with a molding die such as a metal die. Each 1 st guided portion 12A1、13A1The first forming die 1 is inclined in the direction opposite to the drawing direction, but is formed at an inclination angle of the same magnitude. In addition, each 2 nd guided portion 12A2、13A2The first forming die 1 is inclined in the direction opposite to the drawing direction, but is formed at an inclination angle of the same magnitude.
In the engaged body 10, the 1 st guided portion 12A1And the 1 st guided portion 13A1The distance in the sandwiching direction is slightly smaller toward the insertion direction of the 1 st guided rail portion 12 and the 2 nd guided rail portion 13 into the 1 st guiding rail portion 22 and the 2 nd guiding rail portion 23. In the engaged body 10, the 2 nd guided portion 12A2And the 2 nd guided portion 13A2The interval in the sandwiching direction becomes smaller toward the insertion direction of the 1 st guided rail portion 12 and the 2 nd guided rail portion 13 into the 1 st guiding rail portion 22 and the 2 nd guiding rail portion 23. In the engaged body 10, the 2 nd guided part 12A2And the 2 nd guided portion 13A2Is more varied than the 1 st guided portion 12A1And the 1 st guided portion 13A1The respective 2 nd guided portions 12A are set so that the variation of the interval is large2、13A2The 1 st guided region T1 and the 2 nd guided region T2Magnitude in direction.
Each of the guide wall surfaces 22A, 23A has: the 1 st guide part 22A1、23A1So as to be in contact with the 1 st guided portion 12A1、13A1Inclined at the same inclination angle and engaged with the 1 st guided part 12A when the engaged part 11 and the engaging part 21 are at the engagement completion position1、13A1Arranged in parallel and opposite to each other; and 2 nd guide part 22A2、23A2So as to be in contact with the 2 nd guided portion 12A2、13A2Inclined at the same inclination angle and engaged with the 2 nd guided part 12A when the engaged part 11 and the engaging part 21 are at the engagement completion position2、13A2Are arranged in parallel and facing each other (fig. 3 to 7).
In the lock structure 1, in conjunction with the linear assembly operation between the 1 st assembly member 110 and the 2 nd assembly member 120, the 1 st guided rail portion 12 is inserted into the 1 st guide rail portion 22 and the 2 nd guided rail portion 13 is inserted into the 2 nd guide rail portion 23 while the engaged body 10 and the engaging body 20 approach each other. Further, in this lock structure 1, the straight line type assembling operation between the 1 st assembling member 110 and the 2 nd assembling member 120 is continued, so that the 1 st guided rail portion 12 is guided by the 1 st guiding rail portion 22, and the 2 nd guided rail portion 13 is guided by the 2 nd guiding rail portion 23. In the lock structure 1, when the assembly of the 1 st assembly member 110 and the 2 nd assembly member 120 is completed, the engagement of the engaged portion 11 and the engaging portion 21 is completed.
Here, in the lock structure 1, the guide portion 22A is guided with respect to the 1 st part1、23A1Interval of (2), the 2 nd guided portion 12A2、13A2By the 1 st guide part 22A1、23A1The interval on the side where the guidance is started (in other words, the front end on the side where the insertion is started when the 1 st guided rail portion 12 is inserted into the 1 st guide rail portion 22, and the front end on the side where the insertion is started when the 2 nd guided rail portion 13 is inserted into the 2 nd guide rail portion 23) is small. That is, at the start of the connection operation between the engaged body 10 and the engaging body 20, the insertion direction of the guided wall surfaces 12A and 13A by the guide wall surfaces 22A and 23A may be in the same directionLarge gaps are provided between the guided wall surface 12A and the guide wall surface 22A and between the guided wall surface 13A and the guide wall surface 23A, respectively. Therefore, in the lock structure 1, the insertion work is easily performed when the 1 st guided rail portion 12 and the 2 nd guided rail portion 13 are inserted into the 1 st guide rail portion 22 and the 2 nd guide rail portion 23, respectively. Therefore, the lock structure 1 can improve the connection workability between the engaged body 10 and the engaging body 20.
Further, in the lock structure 1, when the insertion is performed and the engaged portion 11 and the engaging portion 21 are at the engagement completion position, the guided wall surfaces 12A and 13A are sandwiched by the guide wall surfaces 22A and 23A, the guided wall surface 12A and the guide wall surface 22A are disposed to face each other in a state of being close to each other, and the guided wall surface 13A and the guide wall surface 23A are disposed to face each other in a state of being close to each other. That is, when the engaged portion 11 and the engaging portion 21 reach the engagement completion position, the respective gaps between the guided wall surface 12A and the guide wall surface 22A and between the guided wall surface 13A and the guide wall surface 23A can be changed to a slight gap. In the lock structure 1, when the engaged portion 11 and the engaging portion 21 are at the engagement completion position, the 1 st guided portion 12A1And the 1 st guide part 22A1Arranged in parallel and facing each other, and the 1 st guided portion 13A1And the 1 st guide part 23A1Are arranged in parallel to each other and face each other, and the 2 nd guided portion 12A2And the 2 nd guide part 22A2Are arranged in parallel and face each other, and the 2 nd guided portion 13A2And the 2 nd guide part 23A2Are arranged in parallel and face each other. Therefore, in the lock structure 1, the backlash between the engaged body 10 and the engaging body 20 can be suppressed in the sandwiching direction of the guided wall surfaces 12A and 13A by the guide wall surfaces 22A and 23A. Therefore, even if an external input such as vibration is applied in the sandwiching direction, the locking structure 1 can suppress a relative positional shift in the sandwiching direction between the engaged body 10 and the engaging body 20, and thus can hold the engaged portion 11 and the engaging portion 21 in the engaged state and the 1 st assembly member 110 and the 2 nd assembly member 120 in the assembled state.
Further, in the locking structure 1, inWhen the engaged portion 11 and the engaging portion 21 are at the engagement completion position, the engaged member 10 and the engaging member 20 can be engaged with each other by the engaged portion 11 and the engaging portion 21 while being shifted in position in the pulling-out direction, and the second guided portion 12A can be engaged with the second guided portion 22And the 2 nd guide part 22A2And the 2 nd guided portion 13A2And the 2 nd guide part 23A2The engaging body 20 can be engaged with the engaged body 10 by a positional deviation in the assembling direction. In the lock structure 1, a pair of second guided portions 12A arranged in parallel and in close proximity to each other are used to face each other2And the 2 nd guide part 22A2And a pair of No. 2 guided parts 13A2And the 2 nd guide part 23A2The looseness between the engaged body 10 and the engaging body 20 in the assembling direction between the engaged body 10 and the engaging body 20 can be suppressed. Therefore, even if an external input such as vibration is applied in the assembling direction or the extracting direction of the engaged body 10 and the engaging body 20, the lock structure 1 can suppress a relative positional shift between the engaged body 10 and the engaging body 20 in the assembling direction or the extracting direction, and can hold the engaged portion 11 and the engaging portion 21 in the engaged state and the 1 st assembly member 110 and the 2 nd assembly member 120 in the assembled state.
Thus, the lock structure 1 can improve the connection workability between the engaged body 10 and the engaging body 20 and suppress the backlash between the engaged body 10 and the engaging body 20. Therefore, the lock structure 1 can obtain good connecting workability and can hold the 1 st assembling member 110 and the 2 nd assembling member 120 in the assembled state.
Here, in order to enhance the effect of improving the workability of connection between the engaged body 10 and the engaging body 20 and the effect of suppressing looseness between the engaged body 10 and the engaging body 20, the lock structure 1 preferably improves the 2 nd guided portion 12A of the guided wall surfaces 12A and 13A2、13A2The ratio of (A) to (B). Therefore, the respective guided wall surfaces 12A, 13A are formed, for example, so that the size of the 1 st guided region T1 and the 2 nd guided region T2 in the assembling direction of the 1 st assembling member 110 and the 2 nd assembling member 120 is equal, as long as the 1 st guided portion 12A is1、13A1And the 2 nd guided portion 12A2、13A2The ratio of (a) to (b) is substantially equal. In addition, the respective guided wall surfaces 12A, 13A are formed, for example, such that the size of the 2 nd guided region T2 in the assembling direction of the 1 st assembling member 110 and the 2 nd assembling member 120 is larger than the size of the 1 st guided region T1 in the assembling direction, as long as the 2 nd guided portion 12A is formed2、13A2Ratio of the occupied ratio of the 1 st guided portion 12A1、13A1Has a high proportion of (A).
The lock structure 1 of the present embodiment will be described in detail below using one of specific examples of the engaged body 10 and the engaging body 20.
In this example, the 1 st assembly member 110 and the 2 nd assembly member 120 are molded with an insulating material such as a synthetic resin, and the engaged body 10 and the engaging body 20 are also molded with an insulating material such as a synthetic resin. Here, the engaged body 10 and the 1 st assembly member 110 are integrally formed, and the engaging body 20 and the 2 nd assembly member 120 are integrally formed.
Here, a case where the 1 st assembly member 110 and the 2 nd assembly member 120 are used in constituent elements of the electrical connection box 200 is exemplified (fig. 9 and 10). Therefore, in this electrical connection box 200, the 1 st assembly member 110 and the 2 nd assembly member 120 each have the lock structure 1. Further, the electrical connection box 200 includes a housing 201 (fig. 10) for accommodating the object 300.
Here, the object 300 is, for example, an electronic component 301 electrically connected to the electric wire We (fig. 9) inside the housing 201 or an electronic component holder 302 (fig. 10) that holds and holds the electronic component 301 inside the housing 201. The electronic component 301 is, for example, a circuit protection component such as a relay or a fuse, a connector, a terminal fitting, or the like. In the present embodiment, an electronic device such as a circuit board or an electronic control unit (so-called ECU) may be considered as one form of the electronic component 301. The electronic component holder 302 is a component called a module, a cartridge, or the like. Inside the housing 201 of this example, a plurality of electronic components 301 and a plurality of electronic component holders 302 are housed. Therefore, in the housing 201 of this example, the electric wire We electrically connected to the electronic component 301 is also housed inside, and the electric wire We is pulled out from inside to outside (fig. 9). The electrical connection box 200 constitutes a wire harness WH (fig. 9) together with the object 300 (electronic component 301, electronic component holder 302) and the electric wire We.
The frame 201 is molded from a synthetic resin material. The housing 201 is a housing box (fig. 9 and 10) formed by assembling a plurality of housing members (1 st housing member 210, 2 nd housing member 220, 3 rd housing member 230) to each other. The 1 st frame member 210 is a cylindrical member having both ends opened, and is a so-called frame (fig. 10). In the housing 201, the object 300 to be housed (the electronic component 301 and the electronic component holder 302) is housed inside the 1 st housing member 210. The 2 nd frame member 220 is a lid member that closes one opening of the 1 st frame member 210, and is a so-called upper lid (fig. 10). The 3 rd frame member 230 is a lid member that closes the other opening of the 1 st frame member 210, and is a so-called lower lid (fig. 10).
In the electrical junction box 200, the object 300 is defined as the 1 st assembly member 110, and the 1 st frame member 210 accommodating the object 300 is defined as the 2 nd assembly member 120. That is, the housing 201 includes the 1 st housing member 210 as the 2 nd assembly member 120, and the 1 st housing member 210 houses and assembles the object 300 to be housed as the 1 st assembly member 110 by a linear assembly operation. Here, the electronic component holder 302 is used as the 1 st assembly component 110 (fig. 10). The electronic component holder 302 is received from the other opening of the 1 st frame member 210 as the 2 nd assembly member 120 (fig. 11).

The outer peripheral surface 302a is disposed to face an inner peripheral surface 211a (fig. 12) of the outer peripheral wall 211 of the 1 st frame member 210 when the electronic component holder 302 is accommodated in the 1 st frame member 210. However, the 1 st frame member 210 of this example adopts a double-walled structure in which an inner peripheral wall 212 is provided inside the outer peripheral wall 211. Therefore, the engaging body 20 is provided on the inner peripheral surface 211a of the outer peripheral wall 211 and is also formed by the inner peripheral wall 212 (fig. 12).
The engaged body 10 of this example has a flexible sheet portion 14 (fig. 13) disposed facing the outer peripheral surface 302a of the electronic component holder 302 with a space therebetween.

In the 1 st guided rail portion 12, a wall surface of the 1 st wall portion 15a on the opposite side to the engaged portion 11 side is used as the guided wall surface 12A. In addition, in the 1 st guided rail portion 12, the end surface on the projecting direction side of the 2 nd wall portion 15b is also used as the guided wall surface 12A. The guided wall surface 12A of the 1 st wall portion 15a is disposed closer to the engaged portion 11 side than the guided wall surface 12A of the 2 nd wall portion 15 b. That is, the 1 st guided rail portion 12 includes: a 1 st guided wall surface 12Aa as a guided wall surface 12A provided on the 2 nd wall portion 15 b; and a 2 nd guided wall surface 12Ab (fig. 13) as a guided wall surface 12A provided on the 1 st wall portion 15a and closer to the engaged portion 11 side than the 1 st guided wall surface 12 Aa.
Further, in the engaged body 10 of this example, the 2 nd guided rail portion 13 is formed by the plate-shaped 3 rd wall portion 15c and the plate-shaped 4 th wall portion 15d (fig. 13). The 3 rd wall part 15c protrudes from the outer peripheral surface 302a, and extends in the assembling direction of the electronic component holder 302 and the 1 st frame member 210 and in the pulling-down direction from the 1 st forming die.

Here, the 3 rd wall portion 15c is provided perpendicularly from the outer peripheral surface 302a, and the 4 th wall portion 15d is provided perpendicularly from the end portion on the projecting direction side of the 3 rd wall portion 15c, so that the L-shaped 2 nd guided rail portion 13 is formed.
In the 2 nd guided rail portion 13, a wall surface of the 3 rd wall portion 15c on the opposite side to the engaged portion 11 side is used as the guided wall surface 13A. In addition, in the 2 nd guided rail portion 13, the end surface on the projecting direction side of the 4 th wall portion 15d is also used as the guided wall surface 13A. The guided wall surface 13A of the 3 rd wall portion 15c is arranged closer to the engaged portion 11 than the guided wall surface 13A of the 4 th wall portion 15 d. That is, the 2 nd guided rail portion 13 includes: a 1 st guided wall surface 13Aa as a guided wall surface 13A provided on the 4 th wall portion 15 d; and a 2 nd guided wall surface 13Ab (fig. 13) as a guided wall surface 13A provided on the 3 rd wall portion 15c and closer to the engaged portion 11 side than the 1 st guided wall surface 13 Aa.
