[Technical field]

[0001] The present invention relates to a connector. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as a connector, for example as described in Patent Document 1, a shielded connector having a shielding function by disposing a shielding member around a housing is known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-079483 A Summary of the Invention [Problem to be solved by the invention]

[0004] Such a connector has room for improvement in that it may be difficult to connect to the connection object. For example, in the above-mentioned shielded connector, an electric wire pull-out portion may be formed in the housing. The electric wire pull-out portion is a portion for pulling out electric wires from the inside of the housing to the outside, and is formed in a cylindrical shape. In this case, if it is attempted to cover the electric wire pull-out portion with a shielding member, it is conceivable to sandwich and cover the electric wire pull-out portion with two semi-cylindrical shielding members. In this case, it is conceivable to fasten the two shielding members together to the connection object with a fastening member to fix the connector to the connection object. In this case, before the two shielding members are fastened together to the connection object, they move away from the state in which they are arranged to sandwich the electric wire pull-out portion, making it difficult to connect the connector.

[0005] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide a connector that can be easily connected to an object to be connected. [Means for solving the problem]

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.

[0010] [Embodiment] This embodiment relates to a connector. In the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "drawing direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "connection direction Z". Here, the drawing direction X, the width direction Y, and the connection direction Z are mutually orthogonal. Note that the orthogonality referred to here includes approximate orthogonality. The drawing direction X corresponds to the drawing direction of the electric wire drawn from the connector. The connection direction Z corresponds to the direction in which the connector is connected to the connection object. In addition, each direction used in the following description represents the direction in the state where each part is assembled to each other unless otherwise specified.

[0011] As shown in FIGS. 1 and 2, the connector 1 is a shield connector used for connection to a connection object 90, and includes a housing 2, a shell upper 3, and a shell lower 4. The connector 1 is mounted on a vehicle, for example, and is configured to accommodate components such as terminals and draw out electric wires from the inside to the outside. The connection object 90 is a vehicle unit mounted on or provided in a vehicle, for example.

[0012] The housing 2 is a component that holds components such as terminals, and is formed by resin molding, for example. The housing 2 has a main body 21 having a box shape. The main body 21 is a hollow box body, and an opening 21A is formed by opening one wall surface. A flange 23 is provided on the main body 21. The flange 23 is a plate-like part extending in a direction intersecting the connection direction Z from the surface of the main body 21, and forms a mounting hole 231 through which a stud bolt 92 is inserted. The mounting hole 231 is formed toward the connection direction Z and is formed so as to penetrate the flange 23. A plurality of flanges 23 are provided, for example, three flanges are provided, and they are provided at intervals in the drawing direction X and the width direction Y.

[0013] An electric wire pull-out portion 22 is formed in the housing 2. The electric wire pull-out portion 22 is a portion for pulling out an electric wire (not shown) from inside the housing 2 to the outside. The electric wire pull-out portion 22 protrudes from the main body 21 in a direction intersecting the connection direction Z, and is formed, for example, along the pull-out direction X. The electric wire pull-out portion 22 has a cylindrical shape and is formed so that an electric wire can be inserted therein. For example, two sets of electric wire pull-out portions 22 are provided, with two electric wire pull-out portions 22 forming one set. In other words, two electric wire pull-out portions 22 are formed side by side in the width direction Y, and the two sets are provided at positions sandwiching the main body 21.

[0014] The housing 2 is formed with a fitting portion 20. The fitting portion 20 is a portion that is fitted with the connection object 90. The fitting portion 20 protrudes in the connection direction Z from a surface of the main body 21 of the housing 2 that faces the connection object 90.

[0015] The shell upper 3 is a shielding member that covers the housing 2 from the side opposite the connection object 90, and is formed of, for example, metal. The shell upper 3 covers the housing 2 and functions as an electromagnetic shield for the housing 2 while also functioning as a protective member for the housing 2. The shell upper 3 is formed, for example, larger than the housing 2 and is provided so as to cover the opening 21A of the main body 21 of the housing 2 while extending an edge portion in the connection direction Z and covering the side portion of the housing 2 with this edge portion.

[0016] A flange portion 33 is formed on the shell upper 3. The flange portion 33 is a plate-shaped portion extending outward from the outer edge portion of the main body 31 of the shell upper 3. The flange portion 33 forms an insertion hole 331 through which the stud bolt 92 is inserted. The insertion hole 331 is formed in the connection direction Z and is formed so as to penetrate the flange portion 33. A plurality of flange portions 33 are provided and are formed at positions corresponding to the flanges 23. For example, three flange portions 33 are provided and are provided spaced apart from each other in the drawing direction X and the width direction Y.

[0017] The shell upper 3 is provided with a cover portion 32. The cover portion 32 is a portion that covers the electric wire pull-out portion 22 of the housing 2. The cover portion 32 is formed at a position corresponding to the electric wire pull-out portion 22, and covers the electric wire pull-out portion 22 from the opposite side of the connection object 90. The cover portion 32 has a semi-cylindrical portion and covers half of the cylindrical electric wire pull-out portion 22. In FIG. 2, the cover portion 32 has semi-cylindrical portions formed side by side in the width direction Y, corresponding to the electric wire pull-out portions 22 formed side by side in the width direction Y.

[0018] The shell upper 3 is configured to be able to be assembled to, for example, the housing 2. For example, one of a recess and a protrusion is formed on the shell upper 3, and the other of a recess and a protrusion is formed on the housing 2. The shell upper 3 and the housing 2 can be assembled by bringing them close to each other along the connection direction Z and fitting the recess and the protrusion together. Note that this assembly does not firmly fix the shell upper 3 and the housing 2 together.

[0019] The shell lower 4 is a shielding member that covers the housing 2 from the connection object 90 side, and is formed of, for example, metal. The shell lower 4 covers the housing 2 and functions as an electromagnetic shield for the housing 2 while also functioning as a protective member for the housing 2. The shell lower 4 is a plate-shaped member and is installed at the position of the electric wire pull-out portion 22 of the housing 2. For example, the shell lower 4 is formed to a size that covers the electric wire pull-out portion 22 of the housing 2, and is attached so as to sandwich the electric wire pull-out portion 22 between the shell lower 4 and the cover portion 32 of the shell upper 3. The shell lower 4 has a semi-cylindrical portion and covers half of the cylindrical electric wire pull-out portion 22. The shell lower 4, together with the cover portion 32 of the shell upper 3, covers the outer periphery of the electric wire pull-out portion 22, thereby enhancing the electromagnetic shielding properties of the electric wire pull-out portion 22. 2, the shell lower 4 corresponds to the wire pull-out portion 22 which is formed in two parts side by side in the width direction Y, and forms two semi-cylindrical portions side by side in the width direction Y. Two sets of shell lower 4 are provided, one on each side of the main body 21 of the housing 2.

[0020] A flange portion 43 is formed on the shell lower 4. The flange portion 43 is a plate-like portion formed continuous with the semi-cylindrical portion, and forms an insertion hole 431 through which the stud bolt 92 is inserted. The insertion hole 431 is formed in the connection direction Z, and is formed so as to penetrate the flange portion 43. For example, one flange portion 43 is formed for one shell lower 4.

[0021] As shown in FIG. 3, the housing 2 is formed with a locking portion 24. The locking portion 24 is a portion for temporarily fixing the shell lower 4 at a position on the connection object 90 side. The locking portion 24 is formed on a flange 23 provided adjacent to the electric wire pull-out portion 22. The locking portion 24 protrudes from the flange 23 toward the connection object 90 side along the connection direction Z. The locking portion 24 is formed in a hook shape and has a shaft portion 241 and a protrusion 242. The shaft portion 241 is a rod-shaped portion and extends from the flange 23 in the connection direction Z. The protrusion 242 protrudes outward from the tip portion of the shaft portion 241 in the pull-out direction X. The locking portion 24 is formed in a hook shape with the shaft portion 241 and the protrusion 242 bent into an L shape.

[0022] The shell lower 4 has an engaged hole 44 formed therein. The engaged hole 44 functions as an engaged portion that engages with the locking portion 24. The engaged hole 44 is a hole through which the locking portion 24 is inserted. The engaged hole 44 is formed in the connection direction Z and is formed so as to penetrate the flange portion 43. The engaged hole 44 is formed to a size that allows the locking portion 24 to be inserted therethrough, and is an elongated hole along the withdrawal direction X. By making the engaged hole 44 an elongated hole, the shaft portion 241 and the protrusion 242 of the locking portion 24 can be smoothly inserted therethrough.

[0023] The connector 1 includes a nut 5. The nut 5 is a fastening member that fastens the shell upper 3, the housing 2, and the shell lower 4 together to fix them to the connection object 90. For example, the nut 5 is used by screwing onto a stud bolt 92 provided on the connection object 90. In this case, the stud bolt 92 also functions as a part of the fastening member. Note that in FIG. 1, the shell upper 3, the housing 2, and the shell lower 4 are fastened together by screwing the nut 5 onto the stud bolt 92, but for example, the shell upper 3, the housing 2, and the shell lower 4 may be fastened together by screwing a bolt into a screw hole formed in the connection object 90.

[0024] Next, the connection of the connector 1 according to this embodiment will be described.

[0025] To connect the connector 1 and the object to be connected 90, first, the housing 2 and the shell upper 3 are assembled as shown in Fig. 4. For example, the housing 2 is attached to the shell upper 3 such that the opening 21A of the housing 2 faces the shell upper 3 and the shell upper 3 covers the opening 21A of the housing 2. In this way, the housing 2 and the shell upper 3 are integrated. At this time, the cover portion 32 of the shell upper 3 covers half of the electric wire pull-out portion 22 of the housing 2. In other words, the cover portion 32 covers the electric wire pull-out portion 22 from the side opposite the object to be connected 90.

[0026] Then, the shell lower 4 is assembled. The shell lower 4 is assembled so as to sandwich the electric wire pull-out portion 22 between itself and the shell upper 3. That is, the shell lower 4 is attached so as to sandwich the electric wire pull-out portion 22 between the cover portion 32 of the shell upper 3 and the shell lower 4. At this time, the shell lower 4 is attached to the housing 2 so that the locking portion 24 of the housing 2 is inserted into the locked hole 44, as shown in FIG. 3 .

[0027] 5, once the shell lower 4 is positioned so as to cover the electric wire pull-out portion 22, the shell lower 4 is slid toward the main body 21 of the housing 2 along the pull-out direction X. This temporarily fixes the shell lower 4 in place so that it does not come off from the housing 2.

[0028] 3, by sliding the shell lower 4 in the drawing-out direction X, the protrusions 242 of the locking portions 24 are inserted through the locking holes 44 and locked to the edges of the locking holes 44. Therefore, the locking of the locking portions 24 prevents the shell lower 4 from coming off from the housing 2 in the connection direction Z.

[0029] 1, the upper shell 3 is assembled to the housing 2, and the lower shell 4 is temporarily fixed to the housing 2, and the connector 1 is then fitted to the object 90. At this time, the lower shell 4 is prevented from falling off the housing 2, so that the fitting of the connector 1 can be performed smoothly. Therefore, the connector 1 can be easily connected to the object 90.

[0030] Then, the stud bolt 92 of the connection object 90 is inserted through the flange portion 43 of the shell lower 4, the flange 23 of the housing 2, and the flange portion 33 of the shell upper 3. By tightening the nut 5 onto the stud bolt 92, the shell lower 4, the housing 2, and the shell upper 3 are fastened together by the stud bolt 92 and the nut 5, and the connector 1 is connected to the connection object 90.

[0031] As described above, the connector 1 according to this embodiment can enhance the electromagnetic shielding properties of the electric wire pull-out portion 22 of the housing 2 by sandwiching and covering the electric wire pull-out portion 22 between the upper shell 3 and the lower shell 4. Furthermore, the connector 1 according to this embodiment can prevent the lower shell 4 from coming off the housing 2 when the housing 2 is connected to the object to be connected 90 by allowing the lower shell 4 to be temporarily fixed to the housing 2 by the locking portion 24 of the housing 2. Therefore, the connector 1 according to this embodiment can be easily connected to the object to be connected 90.

[0032] Furthermore, in the connector 1 according to the present embodiment, the hook-shaped locking portion 24 is inserted into the locking hole 44, thereby enabling the shell lower 4 to be provisionally secured to the housing 2 accurately. Furthermore, in the connector 1 according to the present embodiment, the hook-shaped locking portion 24 is provided on the housing 2, and the locking hole 44 is formed in the shell lower 4, thereby enabling the shell lower 4 to be provisionally secured to the housing 2 despite the simple locking structure, and facilitating connection to the connection object 90.

[0033] The connector according to the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The connector 1 according to this embodiment may be configured by appropriately combining the components of the embodiments and modified examples described above.

[0034] For example, the connector 1 according to the above embodiment has been described as being mounted on a vehicle, but it may also be used without being mounted on a vehicle. [Explanation of symbols]
