Description

[Technical field]

[0001] The present invention relates to a connector that is attached to a cable. [Background technology]

[0002] For example, Patent Document 1 discloses this type of connector.

[0003] Referring to FIG. 30, the connector 90 disclosed in Patent Document 1 is attached to a cable 98. The connector 90 includes a shield shell 92 having a braided crimping piece (barrel) 94, and a sleeve 96. Referring to FIG. 31, the cable 98 includes a braid 984 and an outer sheath 982 that covers the braid 984. An end of the braid 984 is exposed from the outer sheath 982. The sleeve 96 is crimped to the braid 984. Referring to FIG. 32, an end of the braid 984 is folded back to cover the sleeve 96. Referring to FIG. 30, a part of the barrel 94 is crimped to the braid 984 that covers the sleeve 96. As a result, the braid 984 is electrically connected to the shield shell 92 via the sleeve 96.

[0004] In general, the sleeve 96 is strongly crimped to the cable 98 and is firmly fixed to the cable 98. On the other hand, if the barrel 94 is strongly crimped to the sleeve 96, problems may occur in the electrical connection. For this reason, the barrel 94 is relatively weakly crimped. As a result, when the cable 98 is pulled strongly, the barrel 94 is deformed to open, and the sleeve 96 together with the cable 98 may move relatively to the barrel 94 and become displaced. On the other hand, referring to FIG. 31, the sleeve 96 has a cylindrical main body 962 and a protruding piece (protruding portion) 964. The protruding portion 964 is provided on the outer circumferential surface of the main body 962 and protrudes from the main body 962. Referring to FIG. 30, even if the barrel 94 is deformed to open due to a force applied to the cable 98 and the sleeve 96 and the cable 98 move toward the right side of FIG. 30, the protruding portion 964 hits the end of the barrel 94 and the movement of the cable 98 stops. That is, the positional deviation of the sleeve 96 with respect to the barrel 94 is suppressed. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] 1, a cable-attached connector 10 according to an embodiment of the present invention includes a connector 12 and a cable 18. The connector 12 is attached to the cable 18. That is, the connector 12 of this embodiment is a connector 12 that is attached to the cable 18.

[0021] Referring to FIG. 2, the cable 18 of this embodiment includes two electric wires 72, a braid 76 made of a conductor, and an outer sheath 78 made of an insulator. The braid 76 is formed by weaving thin wires made of a metal such as copper into a net shape. Each of the electric wires 72 includes a core wire 73 made of a conductor and a sheath 74 made of an insulator. Each of the sheaths 74 covers the core wire 73. The front end of each of the core wires 73 in the front-rear direction is exposed from the sheath 74. The front-rear direction in this embodiment is the X direction. In this embodiment, the front is the +X direction, and the rear is the -X direction. In the present invention, terms indicating a positional relationship such as the front-rear direction do not indicate an absolute positional relationship with respect to the ground, but merely indicate a relative positional relationship when the direction in which the illustrated cable 18 extends is defined as the front-rear direction.

[0022] The two electric wires 72 are covered with a braid 76 in an orthogonal plane (YZ plane) perpendicular to the front-rear direction, and are thereby electromagnetically shielded. The braid 76 is covered with an outer sheath 78 in the orthogonal plane. The front end of the braid 76 is exposed from the outer sheath 78. The front end of the electric wires 72 is exposed from the braid 76. The cable 18 of this embodiment has the above-mentioned structure. However, the present invention is not limited to this, and the structure of the cable 18 can be modified as necessary. For example, the number of electric wires 72 may be one, or three or more.

[0023] 1, connector 12 is attached to the front end in the front-rear direction of cable 18. That is, connector 12 of the present embodiment is a connector 12 that is attached to the front end in the front-rear direction of cable 18. Connector 12 of the present embodiment (see FIG. 1) will be described below.

[0024] The connector 12 of this embodiment includes a metal front shell 13, a metal connector body 14, and a metal sleeve 16. The front shell 13, the connector body 14, and the sleeve 16 of this embodiment are each formed by bending a single metal plate. The connector 12 of this embodiment includes the above-mentioned three members. However, the present invention is not limited to this. For example, the connector 12 may further include another member in addition to the above-mentioned three members. On the other hand, the connector 12 may not include the front shell 13. The connector body 14 may be formed by joining a plurality of metal plates.

[0025] 3 together with FIG. 1, the connector 12 of this embodiment can be connected along the front-rear direction to an object 80 located in front of it in the front-rear direction. The connector body 14 has a main body 20 and a barrel 30. The barrel 30 is located behind the main body 20 in the front-rear direction. More specifically, the main body 20 of this embodiment is located at the front end of the connector body 14. When the connector 12 is in an attached state in which it is attached to the cable 18, the main body 20 receives an exposed core wire 73 (see FIG. 2) of the electric wire 72 (see FIG. 2). The barrel 30 of this embodiment is located at the rear end of the connector body 14. The main body 20 and the barrel 30 are integrally formed with each other.

[0026] The connector body 14 in this embodiment is a back shell of the connector 12. The main body 20 and the barrel 30 are each a part of the back shell. The main body 20 of the connector body 14 is covered by the front shell 13. The front shell 13 can be connected to the target object 80 together with the main body 20 of the connector body 14. However, the present invention is not limited to this. For example, if the front shell 13 is not provided, only the main body 20 may be connectable to the target object 80.

[0027] Referring to FIG. 1, the object 80 of this embodiment is an external housing that receives and holds the front shell 13 and the connector body 14. The object 80 of this embodiment can be mated with a mating connector (not shown) while holding the front shell 13 and the connector body 14. That is, the connector 12 of this embodiment can be mated with a mating connector located forward in the front-rear direction along the front-rear direction. When the object 80 holding the front shell 13 and the connector body 14 is mated with the mating connector, the electronic device (not shown) connected to the cable 18 is electrically connected to the mating electronic device (not shown) connected to the mating connector. However, the present invention is not limited to this. For example, the object 80 may be a mating connector connected to the mating electronic device.

[0028] 3, the sleeve 16 of this embodiment includes a first sleeve 42 and a second sleeve 46. Each of the first sleeve 42 and the second sleeve 46 has a shape that opens downward in the up-down direction perpendicular to the front-rear direction when the connector 12 is in a pre-attachment state in which it is not attached to the cable 18 (see FIG. 5). The up-down direction in this embodiment is the Z direction. In this embodiment, the up is the +Z direction and the down is the -Z direction.

[0029] More specifically, each of the first sleeve 42 and the second sleeve 46 has two side plates. In each of the first sleeve 42 and the second sleeve 46, the two side plates are located on both sides of the sleeve 16 in a lateral direction perpendicular to both the front-rear direction and the up-down direction. The upper ends of the two side plates are connected to each other, and the lower ends of the two side plates are separated from each other in the lateral direction. In this embodiment, the lateral direction is the Y direction.

[0030] 4 and 5, when the connector 12 is attached to the cable 18, the first sleeve 42 is crimped and fixed to the outer sheath 78 of the cable 18, and the second sleeve 46 is crimped and fixed to the braid 76 of the cable 18. That is, when the connector 12 is in the attached state, the first sleeve 42 surrounds the outer sheath 78 in the orthogonal plane (YZ plane) and is fixed to the outer sheath 78, and the second sleeve 46 surrounds the braid 76 in the orthogonal plane and is fixed to the braid 76.

[0031] According to this embodiment, after the second sleeve 46 is crimped to the braid 76, the braid 76 is folded back, so that the second sleeve 46 is covered by the braid 76 in the orthogonal plane (YZ plane). In particular, according to this embodiment, when the connector 12 is in the attached state, the second sleeve 46 covers the braid 76 in the orthogonal plane and is completely covered by the folded back braid 76. This structure allows the second sleeve 46 to be in contact with the braid 76 reliably. However, the present invention is not limited to this. For example, the folded back braid 76 may partially cover the second sleeve 46 in the orthogonal plane. Also, the braid 76 may not be folded back to the rear. In other words, the outer circumferential surface of the second sleeve 46 may not be covered by the braid 76.

[0032] According to this embodiment, when the connector 12 is in the attached state, each of the first sleeve 42 and the second sleeve 46 has a cylindrical shape with no gap surrounding a central axis AX parallel to the front-rear direction, and extends along the front-rear direction. However, the present invention is not limited to this. For example, each of the first sleeve 42 and the second sleeve 46 may have a polygonal shape such as a hexagonal shape in an orthogonal plane (YZ plane). Also, when the connector 12 is in the attached state, each of the joints of the first sleeve 42 and the second sleeve 46 may be slightly open.

[0033] 3 together with FIG. 5, the sleeve 16 of the present embodiment has a connecting portion 44 in addition to the first sleeve 42 and the second sleeve 46. The connecting portion 44 extends along the front-rear direction and connects the first sleeve 42 and the second sleeve 46 to each other. The second sleeve 46 is located in front of the first sleeve 42. By providing the connecting portion 44, the first sleeve 42 and the second sleeve 46 can be formed integrally with each other, making it easy to crimp the first sleeve 42 and the second sleeve 46 to the outer jacket 78 and the braid 76, respectively.

[0034] The sleeve 16 of this embodiment has the structure described above. However, the present invention is not limited to this, and the structure of the sleeve 16 can be modified in various ways. For example, the sleeve 16 may have only the second sleeve 46. Also, the first sleeve 42 and the second sleeve 46 may be separate members. In this case, it is not necessary to provide the connecting portion 44.

[0035] The first sleeve 42 and the second sleeve 46 may each be a separate cylinder when the connector 12 is in a pre-installed state. In this case, the cable 18 may be inserted inside the first sleeve 42 and the second sleeve 46, and the first sleeve 42 and the second sleeve 46 may be disposed to surround the jacket 78 and the braid 76, respectively. The first sleeve 42 and the second sleeve 46 may then be crimped to the jacket 78 and the braid 76, respectively.

[0036] 3, the barrel 30 of the present embodiment includes a first barrel (barrel) 32 corresponding to the first sleeve 42 and a second barrel (barrel) 36 corresponding to the second sleeve 46. That is, the connector main body 14 of the present embodiment has two barrels 32, 36. The two barrels 32, 36 are located rearward of the main body 20 in the front-rear direction, and have an upwardly open shape when the connector 12 is in a pre-attachment state.

[0037] 4 and 6, when the connector 12 is attached to the cable 18, the first barrel 32 is fixed to the first sleeve 42 by crimping, and the second barrel 36 is fixed to the second sleeve 46 by crimping via the braid 76. That is, when the connector 12 is in the attached state, the first barrel 32 is fixed to the first sleeve 42 by surrounding the first sleeve 42 in the orthogonal plane (YZ plane), and the second barrel 36 is fixed to the second sleeve 46 by surrounding the second sleeve 46 in the orthogonal plane.

[0038] When the connector 12 is in the attached state, the second barrel 36 and the second sleeve 46 sandwich the braid 76 covering the second sleeve 46 and are in contact with the braid 76, whereby the connector body 14 is electrically connected to the braid 76 of the cable 18. In other words, when the connector 12 is in the attached state, the connector body 14 has the same ground potential as the braid 76 and electromagnetically shields the exposed core wire 73 (see FIG. 2) of the cable 18.

[0039] In this embodiment, the second barrel 36 is crimped to the second sleeve 46 via the braid 76. However, the present invention is not limited to this. For example, when the second sleeve 46 is not covered with the braid 76, the second barrel 36 may be directly crimped to the second sleeve 46. Also, when the second sleeve 46 is a member separate from the first sleeve 42 and has a cylindrical shape, the second sleeve 46 may be inserted inside the braid 76 in the orthogonal plane (YZ plane), and the second barrel 36 may crimp the second sleeve 46 together with the braid 76.

[0040] Each of the first barrel 32 and the second barrel 36 in this embodiment has a cylindrical shape with no gap surrounding the central axis AX and extends along the front-rear direction when the connector 12 is in the attached state. However, the present invention is not limited to this. For example, each of the first barrel 32 and the second barrel 36 may have a polygonal shape such as a hexagonal shape in an orthogonal plane (YZ plane). Furthermore, each of the joints of the first barrel 32 and the second barrel 36 may be slightly open when the connector 12 is in the attached state.

[0041] 3, the barrel 30 of this embodiment has an intermediate portion 34 in addition to the first barrel 32 and the second barrel 36. The intermediate portion 34 extends along the front-rear direction and connects the first barrel 32 and the second barrel 36 to each other. The second barrel 36 is located in front of the first barrel 32. By providing the intermediate portion 34, the first barrel 32 and the second barrel 36 can be integrally formed with each other, and it is easy to crimp the first barrel 32 and the second barrel 36 to the first sleeve 42 and the second sleeve 46, respectively.

[0042] The barrel 30 of the present embodiment has the structure described above. However, the present invention is not limited to this, and the structure of the barrel 30 can be modified in various ways. For example, when the sleeve 16 has only the second sleeve 46, the barrel 30 may have only the second barrel 36. That is, the connector body 14 may have only one barrel. On the other hand, the connector body 14 may have three or more barrels.

[0043] The sleeve 16 of this embodiment will now be described in more detail.

[0044] 4 and 5, the sleeve 16 of this embodiment has a main portion 50 and two protruding portions 52. As described later, the protruding portions 52 are portions for suppressing misalignment of the sleeve 16 with respect to the barrel 30. In this embodiment, the main portion 50 and the protruding portions 52 are provided on the first sleeve 42. This structure makes it easy to cover the second sleeve 46 with the braid 76. However, the present invention is not limited to this. For example, when the second sleeve 46 is not covered with the braid 76 or when the sleeve 16 has only the second sleeve 46, the main portion 50 and the protruding portions 52 may be provided on the second sleeve 46.

[0045] 5, whether the main portion 50 is provided on the first sleeve 42 or the second sleeve 46, the main portion 50 surrounds the cable 18 in an orthogonal plane (YZ plane) and is fixed to the cable 18 when the connector 12 is in the attached state. Each of the projections 52 extends forward from the main portion 50 and has a stopper 58. The stopper 58 is located in front of the main portion 50 and is located outside the main portion 50 in the orthogonal plane when the connector 12 is in the attached state. Referring to FIG. 6, when the connector 12 is in the attached state, the barrel 32 surrounds the main portion 50 in the orthogonal plane and is fixed to the main portion 50, and the stopper 58 of the projection 52 is located in front of the barrel 32.

[0046] 1, the cable-attached connector 10 of this embodiment has the structure described above. In detail, the main portion 50 surrounds the cable 18 in an orthogonal plane (YZ plane) and is fixed to the cable 18. Each of the protrusions 52 extends forward from the main portion 50 and has a stopper 58. The stopper 58 is located in front of the main portion 50 and is located outside the main portion 50 in the orthogonal plane. The barrel 32 surrounds the main portion 50 in the orthogonal plane and is fixed to the main portion 50, and the stopper 58 of the protrusion 52 is located in front of the barrel 32.

[0047] In general, the sleeve 16 is strongly crimped to the cable 18 and firmly fixed to the cable 18. On the other hand, if the barrel 30 is strongly crimped to the sleeve 16, problems may occur in the electrical connection. For example, the transmission characteristics of the connector 12 may be deteriorated. For this reason, the barrel 30 is crimped relatively weakly. As a result, the sleeve 16 may move together with the cable 18 relative to the barrel 30 and become displaced. In particular, if the cable 18 is pulled strongly backward, the sleeve 16 may become displaced.

[0048] On the other hand, the sleeve 16 of the present embodiment has a protrusion 52. The protrusion 52 extends forward from the main portion 50. A stopper 58 of the protrusion 52 is located in front of the main portion 50 and the barrel 32, and protrudes outward beyond the outer circumferential surface of the main portion 50 in the orthogonal plane (YZ plane). The stopper 58 thus formed abuts against the front end of the barrel 32 when the sleeve 16 moves rearward together with the cable 18. As a result, the positional deviation of the sleeve 16 can be suppressed.

[0049] If the projection 52 for preventing misalignment projects outward from the outer circumferential surface of the main portion 50, there is a risk that the barrel 32 will be erroneously crimped onto the projection 52. In this case, there is a risk that the barrel 32 will not be sufficiently fixed to the sleeve 16. Furthermore, if force is applied to the projection 52 when the barrel 32 is crimped, there is a risk that the projection 52 will be damaged.

[0050] On the other hand, according to the present embodiment, even if the barrel 32 is crimped onto the stopper 58, the stopper 58 moves toward the cable 18. Even if the stopper 58 moves significantly, the protrusion 52 is received by the soft outer jacket 78. As a result, damage to the protrusion 52 can be prevented. That is, according to the present embodiment, it is possible to provide a connector 12 having a structure that can suppress misalignment of the sleeve 16 with respect to the barrel 30 and can prevent damage to the sleeve 16 when the barrel 30 is crimped.

[0051] 6, the protrusion 52 in this embodiment is elastically deformable in an orthogonal plane (YZ plane). This structure makes it easy to prevent damage to the protrusion 52. Furthermore, even if a force is applied to the rear end of the stopper 58 when the barrel 32 is crimped, the protrusion 52 returns to its initial shape after the barrel 32 is crimped, thereby suppressing displacement of the sleeve 16.

[0052] 4, 7 and 8, according to this embodiment, the main portion 50 is provided with two protrusions 52. That is, the number of protrusions 52 in this embodiment is two. The two protrusions 52 are located on both sides of the connecting portion 44 in the lateral direction, and have shapes symmetrical to each other with respect to a predetermined plane (XZ plane). With this structure, the positional deviation of the sleeve 16 can be suppressed in a balanced and more reliable manner. However, the present invention is not limited thereto. For example, the two protrusions 52 may have shapes asymmetrical to each other with respect to the predetermined plane. The number of protrusions 52 may be one, or may be three or more.

[0053] The following describes one of the protrusions 52. The following description is also applicable to the other one of the protrusions 52.

[0054] 7, according to this embodiment, the protruding portion 52 is located only in front of the front end of the main portion 50.
