As a prior art document, patent document 1 is JP 2017-45514 A

In order to summarize the invention, the problem to be solved by the invention is first described.

With the configuration mentioned above, however, the plate is required in order to fix the connector. Means for fixing the connector to the panel without using a plate is therefore desirable in order to reduce the number of components.

The present invention was created on the basis of the situation described above and the aim thereof is to create a connector which can be fixed to a panel without using a plate.

As a means for solving the problem, a connector according to the present invention is assembled in a through hole on a panel and comprises: a housing which can be associated with the through hole; a flange portion which extends outwardly from a circumferential surface of the housing and can abut on a first surface side of a circumferential edge portion of the through hole; an electrical cable cover which is disposed on another surface side of the panel and is assembled on the housing; and an abutment portion which is arranged on the electrical cable cover and can abut on said other surface side of the circumferential edge portion of the through hole. The advantages of the invention will then be described.

According to the present invention, a circumferential edge portion of a through hole is held between a flange portion of a housing and an abutment portion of an electrical cable cover, so that a connector can be attached to a sign without using a sign.

The drawings are briefly described below.

A preferred embodiment of the present invention will be described below. The connector according to the present invention may have a configuration in which a locking part arranged on the electric cable cover is locked on a locked part arranged on the housing in order to maintain a state in which the electric cable cover is assembled on the housing. , the circumferential surface of the housing has a curved surface which is curved in an arc shape, the locked part is formed in a circumferential direction of the curved surface, and the locking part can move in the circumferential direction along the locked part in a state in which said locking part is locked on the locked part. Given this configuration, the orientation of the electric cable cover can be changed by turning the electric cable cover in the circumferential direction while the orientation of the housing remains fixed.

In addition, the connector according to the present invention may have a configuration in which the locked part is a groove allowing the fixing of a plate which can be locked on the circumferential edge part of the through hole, and the locking part has a hook part which can be locked in the groove and also serves as a stop part. Given this configuration, the circumferential edge portion of the through hole is held between the flange portion of the housing and the locking portion of the electrical cable cover, so that it is possible to fix a conventional housing, which is fixed on a panel using a plate, on said panel without using the plate.

In addition, the connector according to the present invention may have a configuration in which the locking part is arranged in a position other, with respect to said other surface, than the part in abutment, and a clearance between the locked part and the part of flange is greater than a clearance between the stop part and the flange part. Here, a conventional configuration in which the connector is fixed to the panel by means of a plate and the flange part requires that the clearance between the flat groove (locked part) and the flange part is equal to the thickness dimension of the sign. Housing adapted to the respective panels is therefore necessary when the thickness dimension of the panel varies. Taking into account this configuration, the clearance between the stop part of the electric cable cover and the flange part can, however, be defined so as to coincide with the thickness dimension of the panel, so that it is possible to take into account the thickness dimension of the panel by changing the electrical cable cover. It is therefore possible to use common accommodation.

An exemplary embodiment 1 in which the present invention is implemented in specific terms will be described in detail below with reference to FIGS. 1 to 7.

A connector C according to this exemplary embodiment is assembled in a through hole 11 on a panel (an automatic transmission box (A / T) in this exemplary embodiment) 10. As shown in FIG. 1, the through hole 11 is circular and passes through the panel 10 in the direction of its thickness. As shown in FIG. 4, the connector C comprises: a housing 20 which receives terminal connections T connected to a terminal part of an electric cable W, and an electric cable cover 30 intended to cover a part of the electrical cable W leaving the housing 20. In the following description of the constituent elements, the upper side in FIG. 1 (a surface side conjugated with an associated connector which is not described) is described as above or upwards , and the opposite side is described as below or down.

The housing 20 is generally in the form of a block which can be associated with the through orifice IL A cross section of the housing 20 (a cross section in a direction intersecting the direction associated with the through orifice 11) is circular. A circumferential surface 21 of the housing 20 forms a curved surface which is curved in the shape of an arc around the entire circumference.

As shown in Fig. 4, a plurality of terminal receiving compartments 22 for receiving the terminal connections T is formed on the housing 20. The terminal connections T are inserted from below into the terminal reception compartments 22. The terminal connectors T inserted in the terminal receiving compartments 22 are locked by a cantilever blade 23 and are doubly locked by means of a retaining element 24 fixed on the housing 20 in order to prevent separation down. The retaining element 24 is inserted inside the housing 20 from an opening formed on the circumferential surface 21 of the housing 20. The housing 20 is divided in two, above and below, into a first housing 20F having a surface conjugated with an associated connector, and a second housing 20S comprising a cover fixing part 27 which will be described later.

A flange portion 25 capable of abutting on an upper surface side (a first surface side) of a circumferential edge portion 12 of the through hole 11 is formed on the housing 20. The flange portion 25 s extends substantially at right angles to the outside from the circumferential surface 21 of the housing 20. The flange portion 25 is arranged over the entire circumference of the circumferential surface 21 of the housing 20. The flange portion 25 is formed in one piece with the second housing 20S.

A part of the housing 20 above the flange part 25 forms a mating connector part 26 which can be coupled to an associated connector, and a part below the flange part 25 forms the cover fixing part 27 on which the electric cable cover 30 is fixed. The retaining element 24 is fixed to the mating part of the connector 26.

A locked part 28 on which a locking part 41 arranged on the electric cable cover 30 can be locked is formed on the housing 20. The locked part 28 is formed on the cover fixing part 27. The locked part 28 is a antlers formed in a cavity on the circumferential surface 21 of the cover fixing part 27. A substantially U-shaped plate (not shown) used when a conventional connector is fixed on the panel 10 can be assembled on the locked part 28 .

The locked part 28 extends substantially parallel to the flange part 25, along the circumferential surface 21 of the cover fixing part 27. The locked part 28 is formed at a certain interval from the flange part 25 with a clearance corresponding to the thickness dimension of the panel 10 (a clearance which is equal to the thickness dimension of the panel 10 or slightly greater than the thickness dimension of the panel 10). The locked part 28 is continuous over the entire circumference of the cover fixing part 27.

A lock receiving surface 29 on which a locking surface 47 of the locking part 41 can be locked is formed on the locked part 28 (see Figure 4). The latch receiving surface 29 is substantially orthogonal to the vertical direction (the direction of attachment / separation of the electric cable cover 30).

The electric cable cover 30 is disposed on a lower side of the panel 10 and is fixed to the cover fixing part 27 of the housing 20. The electric cable cover 30 covers part of a bundle of electric cables W exiting through the below from a lower surface of the housing 20, and also causes the curvature of the bundle of electric cables W in a predetermined direction (a perpendicular direction, in this exemplary embodiment) so as to guide the latter. As shown in FIG. 1, the electric cable cover 30 comprises: a main body part of a capsule-shaped cover 31 intended to internally receive a part of the electric cables W, and a guide part 32 which guides the wiring harness W to the outside from the main cover body part 31.

The main cover body part 31 comprises: a wall part 33 which is disposed substantially parallel to and facing the surface of the housing 20 in a state in which the main cover body part 31 is fixed to the housing 20, and an outer circumferential wall 34 which stands vertically from an outer circumferential edge of the bottom wall 33. As shown in FIG. 5, the bottom wall 33 is in the form of a circular plate, and the outer circumferential wall 34 is substantially cylindrical. A vent hole 36 due to the formation of the locking part 41 is formed on the lower wall 33 of the main body part of the cover 31.

The main cover body part 31 can be assembled outside the cover fixing part 27 of the housing 20. A plurality of ribs 35 is formed on the internal surface of the main cover body part 31. ribs 35 extend in a vertical direction through the outer circumferential wall 34 from the bottom wall 33 of the main cover body part 31.

The outlet portion 32 extends outward in a radial direction from a cut portion of the outer circumferential wall 34 (hereinafter referred to as the cut portion 37). As shown in FIG. 5, the outlet part 32 comprises: a lower outlet part 38 connected to the lower wall 33, and a pair of lateral outlet parts 39 connected to the two sides of the cut part 37 of the wall outer circumference 34. As shown in FIG. 7, the outlet part 32 is in the form of a letter U, the pair of lateral outlet parts 39 extending vertically on both sides the lower outlet part 38 The height dimension (dimension in the vertical direction) of the pair of lateral outlet parts 39 is less than or equal to half the height dimension of the outer circumferential wall 34 of the main cover body part 31. As as shown in figure 4, the locking part 41 which can be locked in the locked part 28 of the housing 20 is formed on the electric cable cover 30. A plurality of p locking parts 41 is formed on the outer circumferential wall 34 of the main cover body part 31. As shown in FIG. 5, the locking parts 41 are arranged in certain positions so as to also divide the outer circumference of the main cover body part 31 in the circumferential direction. According to this exemplary embodiment, the locking parts 41 are arranged at three locations so as to divide the external circumference of the main cover body part 31 substantially also in three in the circumferential direction. One of the locking portions 41 of the three locking portions 41 is disposed at a 180 ° position relative to the outlet portion 32 in the circumferential direction along the outer circumferential wall 34. Two of the locking portions 41 among the three locking parts 41 are arranged at positions equidistant from the outlet part 32 in the circumferential direction, along the outer circumferential wall 34.

As shown in FIG. 4, the locking parts 41 include: an elastic part 42 which can be bent in an elastic manner towards the inside and towards the outside (radial direction) of the main body part of the cover 31, and a hook part 43 which can be locked on the locked part 28.

The elastic part 42 is formed along the outer circumferential wall 34 of the main cover body part 31. The elastic part 42 has a cantilever shape in which the lower end is fixed to the body part main cover 31 and the upper end is a free end. As shown in Figure 7, the elastic portion 42 is arranged between a pair of slots 44 formed on the outer circumferential wall 34. The pair of slots 44 extends substantially vertically downward from a surface of upper end 45 of the outer circumferential wall 34. The vertical positions of an upper end surface 46 of the locking portion 41 and the upper end surface 45 of the outer circumferential wall 34 are defined uniformly.

The hook part 43 is arranged at the free end of the elastic part 42. The hook part 43 is formed projecting inwards from the elastic part 42. As shown in FIG. 4, a lower surface of the hook part 43 forms the locking surface 47 which can be locked on the locked part 28. The locking surface 47 is substantially orthogonal to the vertical direction. An upper surface of the hook part 43 is inclined so that the projection dimension from the elastic part 42 gradually increases from an upper end towards a lower end of the hook part 43.

The electric cable cover 30 has a stop part 48 which can come into abutment on the lower surface side (other surface side) of the panel 10 when the electric cable cover 30 is fixed on the housing 20 in a coupling state with the through hole 11 on the panel 10, as shown in FIG. 3. The stop part 48 comprises the upper end surface 45 of the outer circumferential wall 34 of the main cover body part 31, and the upper end surface 46 of the locking portion 41. The abutment portion 48 abuts on the circumferential edge portion 12 of the through hole 11 on the panel 10, theoretically over the entire circumference.

An example of an operation for fixing the connector C of this exemplary embodiment on the panel 10 will then be described.

The housing 20 is firstly coupled to the through hole 11 on the panel 10. As shown in FIG. 1, the housing 20 is inserted into the through hole 11 from the upper surface side of the panel 10, the cover fixing part 27 being directed downwards. When this occurs, the flange portion 25 of the housing 20 abuts on the upper surface of the circumferential edge portion 12 of the through hole 11 (see Figure 2). As a result, it is possible to prevent separation of the housing 20 from below the through hole 11. In a state in which the housing 20 is coupled to the through hole 11 on the panel 10, the locked portion 28 is arranged on the lower side of the panel 10.

The electric cable cover 30 is then assembled on the housing 20. As shown in FIG. 2, the main cover body part 31 is assembled outside the cover fixing part 27 while the harness of electrical cables W exiting from the upper surface of the housing 20 is received on the inside of the main body part of the cover 31 and caused to bend substantially at right angles. Here, the bundle of electric cables W is caused to extend outwards from the outlet part 32. The hook part 43 of the locking part 41 abuts on the circumferential surface 21 of the housing 20 when the main cover body part 31 is coupled to the cover fixing part 27 and the elastic part 42 bends outwardly elastically. When the hook part 43 reaches the locked part 28, the elastic part 42 is resiliently biased inward, and a condition is produced in which the hook part 43 is locked on the locked part 28, in d in other words a state in which the locking surface 47 of the hook part 43 and the latch receiving surface 29 of the locked part 28 are in abutment in the vertical direction (see FIG. 4). As a result, the electric cable cover 30 is assembled on the housing 20 in a state in which the downward separation from the housing 20 is limited. In addition, the abutment portion 48 of the electric cable cover 30 is in an abutment state with the bottom surface of the circumferential edge portion 12 of the through hole 11. As a result, it is possible to prevent the connector C to separate upwards with respect to the through orifice 11. In theory the whole of the stop part 48 of the electric cable cover 30 is in a state of stop with the panel 10, and in theory, the whole of the cover fixing part 27 of the housing 20 is covered by the electric cable cover 30. The orientation of the electric cable cover 30 is then adjusted to a predetermined orientation. When the electric cable cover 30 is turned, the locking part 41 moves in the circumferential direction along the locked part 28 while the locking surface 47 of the locking part 41 remains locked on the receiving surface 29 of the locked part 28. During this time, the orientation of the housing 20 remains unchanged and only the electric cable cover 30 is turned relative to the latter, allowing the position of the outlet part 32 to be modified. When the operation rotation is stopped once the electric cable cover 30 has reached the predetermined orientation, the electric cable bundle W is maintained in a state in which it is guided in a predetermined direction.

The operation of fixing the connector C to the panel 10 is completed according to the above.

The operation and the advantages of the exemplary embodiment presenting the previous configuration will then be described.

The connector C according to this exemplary embodiment is assembled in the through hole 11 on the panel 10 and comprises: the housing 20 which can be coupled to the through hole 11; the flange portion 25 which extends outward from the circumferential surface 21 of the housing 20 and can abut on the upper surface side of the circumferential edge portion 12 of the through hole 11; and the electric cable cover 30 which is arranged on the lower surface side of the panel 10 and is assembled on the housing 20. The electric cable cover 30 comprises the stop part 48 which can come into abutment on the other side of surface of the circumferential edge portion 12 of the through hole 11. In view of this configuration, the circumferential edge portion 12 of the through hole 11 is held between the flange portion 25 of the housing 20 and the stop portion 48 of the electric cable cover 30, so that the connector C can be fixed to the panel 10 without using a plate.

In addition, the locking part 41 arranged on the electric cable cover 30 is locked on the locked part 28 arranged on the housing 20 in order to maintain a state in which the electric cable cover 30 is assembled on the housing 20, the surface circumferential 21 of the housing 20 has a curved surface which is curved in an arc, the locked part 28 is formed in the circumferential direction of the curved surface, and the locking part 41 can move in the circumferential direction along the locked part 28 in a state in which said locking part 41 is locked on the locked part 28. In view of this configuration, the orientation of the electric cable cover 30 can be changed by turning the electric cable cover 30 in the direction circumferential while the orientation of the housing 20 remains fixed.

In addition, the locked part 28 is a groove allowing the fixing of a plate which can be locked on the circumferential edge part 12 of the through hole 11, and the locking part 41 comprises the hook part 43 which can be locked on the groove and also serves as a stop part 48. In view of this configuration, the circumferential edge part 12 of the through hole 11 is held between the flange part 25 of the housing 20 and the locking part 41 of the cover electric cable 30. It is therefore possible to fix a conventional housing 20, which is fixed to a panel 10 using a plate, on said panel 10 without using the plate.

An exemplary embodiment 2 will now be described.

A connector 50 according to the exemplary embodiment 2 in which the present invention is implemented in specific terms will be described in detail using FIGS. 8 to 12.

The connector 50 according to this exemplary embodiment differs from the exemplary embodiment 1 in that an upper end surface 53 of a locking part 52 of an electric cable cover 51 is positioned above below the upper end surface 45 of the outer circumferential wall 34. It should be noted that constituent elements which are identical to those of the example of embodiment 1 have the same reference numerals and will not be described in detail. new.

The connector 50 according to this exemplary embodiment is assembled in a through orifice 11 on a panel 10 in the same manner as in the exemplary embodiment 1, and comprises: the housing 20 which can be coupled with the orifice through 11, and the electric cable cover 51 assembled on the housing 20, the flange part 25 which can abut on the upper surface side of the circumferential edge part 12 of the through orifice 11 is formed on the housing 20, and the stop part 48 which can come into abutment on the lower surface side of the circumferential edge part 12 of the through hole 11 is formed on the electric cable cover 51.

Furthermore, in the connector 50 according to this exemplary embodiment, a locking part 52 arranged on the electric cable cover 51 is locked in a locked part 57 formed on the housing 20 in order to maintain a state in which the cover electric cable 51 is assembled on the housing 20, in the same way as in the example of embodiment 1. The locked part 57 is a groove formed in a cavity on the circumferential surface 21 of the cover fixing part 27 of the same way as in the example of embodiment 1, and the locking part 52 comprises a hook part 55 at an upper end of an elastic part 54. The locking part 52 can move in the circumferential direction along the locked part 57 in a state in which said locking part 52 is locked on the locked part 57, in the same way e as for the example of embodiment 1.

The upper end surface 53 of the locking portion 52 is positioned below the upper end surface 45 of the outer circumferential wall 34. As a result, in a state in which the electric cable cover 51 is assembled on the housing 20, which is itself coupled with the through hole 11 on the panel 10, as shown in Figure 9, the locking portion 52 is disposed at a position below the bottom surface of the panel 10. C that is, only the upper end surface 45 of the outer circumferential wall 34, excluding the upper end surface 53 of the locking part 52, forms the stop part 48.

The locking part 52 according to this exemplary embodiment has a height dimension less than that of the locking part 41 of the exemplary embodiment 1, and the thickness dimension of the elastic part 54 is also less than that of the elastic part 42 of the locking part 41 of the exemplary embodiment 1. As shown in FIG. 10, the thickness dimension of the elastic part 54 is less than the thickness dimension of the wall outer circumference 34 and a bearing 56 is formed at the limit of the inner surface of the elastic part 54 and the inner surface of the circumferential wall 34, and of the outer surface of the elastic part 54 and the outer surface of the outer circumferential wall 34. It should be noted that the air orifice 36 is not formed on the bottom wall 33 of the electric cable cover 51.

As shown in FIG. 10, the position of the locked part 57 of the housing 20 is situated in alignment with the position in height of the locking part 52, below the position in the example of mode of embodiment 1. As a result, the clearance between the flange portion 25 and the locked portion 57 is greater than that of the example of embodiment 1, and it is possible to take into account a panel 10 having a greater thickness dimension to that of panel 10 of the exemplary embodiment 1. The clearance between the stop part 48 and the flange part 25 corresponds to the thickness dimension of the panel 10. By preparing electric cable covers 51 having a dimension at a different height from the stop part 48, corresponding to the thickness dimension of the panel 10, it is possible to fix the connector 50 on panels 10 having different thickness dimensions a when a common housing 20 is still used.

In this exemplary embodiment as described above, in the same manner as in the exemplary embodiment 1, the circumferential edge portion 12 of the through hole 11 is held between the flange portion 25 of the housing 20 and the stop portion 48 of the electric cable cover 51, so that the connector 50 can be fixed to the panel 10 without using a plate. In addition, the locking part 52 is disposed at a position further from the lower surface of the panel 10 than the stop part 48, and the play between the locked part 57 and the flange part 25 is greater than the play between the part stopper 48 and the flange part 25. As a result, the clearance between the stopper part 48 of the electric cable cover 51 and the flange part 25 can be defined so as to correspond to the thickness dimension of the panel 10, so that it is possible to take into account the thickness dimension of the panel 10 by modifying the electric cable cover 51. It is therefore possible to use a common housing 20.
