JP 2006-344490 A

  In the case of the conventional coaxial connector, the center contact is held in the inner housing by inserting the center contact into the contact insertion hole and caulking a predetermined position of the inner shell. Instead of this, it is conceivable to hold the center contact in the inner housing by locking the center contact to the inner housing. In this case, as a measure for locking, it is conceivable to provide a flexible piece on one of the center contact and the inner housing, and provide a convex portion or a concave portion on which the flexible piece is hung on the other. It is also conceivable to press-fit the center contact into the inner housing. However, when the center contact is inserted into the inner housing, for example, when the center contact is displaced from the original insertion track or tilted from the original insertion track and inserted, However, the insertion force is applied to, for example, a flexible piece, a convex portion, a concave portion, a press-fitting portion, or other engaging portion provided in the inner housing more strongly than the original hooking method. There is a possibility that a malfunction may occur in which the connecting portion breaks due to concentrated action on the connecting portion of the central conductor with the central contact.

  The present invention has been made paying attention to such points, and the object of the present invention is to provide an extended portion on the opposite end side of the conductor exposed from the insulation coating of the electric wire, and the contact is located on the back side of the housing. The extension portion is accommodated in the housing chamber on the front side of the housing before contacting the locking portion provided on the inner wall of the housing, and the contact is advanced along the original insertion track by the inner wall forming the housing chamber. By guiding the extension portion in such a manner, it is possible to provide a harness in which the insertion force is prevented from being concentrated on the connection portion of the conductor with the contact, and the connection portion is unlikely to break. is there.

In order to achieve the above object, the first harness of the present invention comprises:
The conductor is processed from an electric wire having an insulating coating covering the conductor, and at one end, the insulating coating is peeled off to expose the conductor, and the insulating coating is formed on the opposite end of the exposed conductor. Including a processed wire provided with an extended portion whose outer periphery is thicker than the conductor,

A housing provided,
The inner wall forming the second storage chamber of the housing and the contact are provided with locking portions that lock each other,
The anti-second accommodation in the inner wall forming the first accommodation chamber of the housing is greater than the distance between the exposed conductor side end surface of the extended portion of the processed wire and the contact start point of the locking portion of the contact. The harness has a longer distance between the chamber-side end and the contact start point of the locking portion of the housing.

  When the contact connected to the conductor is inserted into the first storage chamber of the housing, the contact is accommodated in the second storage chamber, and the locking portions of the housing and the contact are connected to each other. Lock. Further, the extension portion is accommodated in the first storage chamber. In that case, from the relationship between the two distances, the contact start point of the locking portion of the contactor before the locking portions of the housing and the contactor start to be locked, that is, the engagement point of the housing is The expansion portion starts to enter the first storage chamber of the housing before the contact receives the force from the locking portion of the housing upon contact with the contact start point of the stop portion, and thereafter the expansion portion The portion advances while being guided by the inner wall forming the first housing chamber of the housing. Therefore, for example, the possibility that the contact is displaced from the original insertion track or tilted from the original insertion track and inserted by being twisted is reduced, for example, provided on the inner wall forming the second storage chamber. For example, it is possible to reduce the possibility that the engaging portion such as the flexible piece, the convex portion, or the concave portion will be hooked or caught more strongly than the original hooking method, and the insertion force is concentrated on the connection portion of the conductor with the contact. It is difficult to cause a problem that the connecting portion is broken by acting on the.

  Embodiments of the present invention will be described below. FIG. 14 shows a first embodiment of the harness of the present invention. This harness H includes a processed electric wire 100 and an electric connector 200 connected to one end of the processed electric wire 100. As shown in FIG. 4, the processed electric wire 100 is processed from an electric wire including a conductor and an insulating coating covering the conductor. The electric wire may further include other elements in addition to the conductor and the insulating coating. At the one end of the processed wire 100, the insulating coating is peeled off to expose the conductor, and the outer periphery of the exposed conductor including the insulating coating is provided on the opposite end side of the conductor. A thicker extension portion 101 is provided. In this embodiment, the electric wire is a shielded cable. This shielded cable includes an inner conductor 111 and an inner electric wire 110 having an inner insulating coating 112 covering the inner conductor 111, an outer conductor 120 made of a braided wire covering the inner electric wire 110, and an outer insulation covering the outer conductor 120. And a coating 130. Hereinafter, the extending direction of the internal conductor 111 is defined as a depth direction, a direction orthogonal to the depth direction is defined as a width direction, and a direction orthogonal to the depth direction and the width direction is defined as a thickness direction. The front in the direction in which the internal conductor 111 extends is the back, and the opposite side is the front. A shielded cable in which two or more of the internal electric wires are contained in the external conductor is also applicable to the harness of the present invention as the electric wire. In this case, the inner conductor 111 corresponds to the conductor, and the inner insulating coating 112 corresponds to the insulating coating. Therefore, in this embodiment, the direction in which the conductor extends is the direction in which the internal conductor 111 extends. As shown in FIG. 4, the processed wire 100 is a processed shielded cable. At the end of the processed shielded cable, the outer insulation coating 130 is peeled off to expose the outer conductor 120, and the outer conductor 120 and the inner insulation coating 112 are peeled off at the end face side of the inner conductor 111. Thus, the inner conductor 111 is exposed, the cylindrical body 140 is caulked with a pressing force to the exposed portion of the outer conductor 120, and the inner insulating coating 112 and the outer conductor are disposed on the opposite end side of the exposed inner conductor 111. The extended portion 101 is provided by 120 and the cylindrical body 140. The cylinder 140 is made of a conductive material, but may be made of an insulating material. The cylindrical body 140 is originally a rectangular flat plate, and the rectangular flat plate or a curved plate that is gently curved in a U shape when viewed from the depth direction is disposed along the exposed portion of the outer conductor 120. The cylindrical plate having a C-shaped cross section having a slit 141 that cuts in the extending direction of the outer conductor 120, that is, the depth direction, is pressed and caulked so as to be wound around the exposed portion by bending the flat plate into an arc shape. Is formed. Instead of this, the cylindrical body may be formed in a cylindrical shape having no slit and having a continuous outer periphery. At that time, the cylindrical body is fitted into the exposed portion of the outer conductor and then pressed and caulked. As a modified example of the processed electric wire 100, for example, in the processed electric wire 100, the exposed outer conductor 120 is peeled off to expose the inner insulating coating 112. It is also possible to assemble the harness of the present invention.

  The electrical connector 200 includes a contactor 210 and a housing 220 in which the contactor 210 is fitted and the expansion portion 101 is accommodated. The contact 210 is made of a conductive material. The contact 210 includes a barrel 211 caulked with a pressing force to the exposed portion of the inner conductor 111 as the conductor, and an end surface of the inner conductor 111 along a direction in which the inner conductor 111 extends, that is, the depth direction. A contact portion 212 extending in a direction away from the contact portion 212. As shown in FIGS. 5 and 6, the barrel 211 is provided at one end of the contactor 210 and is formed in a U shape in which caulking pieces rise from both sides in the width direction as viewed in the depth direction. Yes. For caulking the inner conductor 111 of the barrel 211 to the exposed portion, the exposed portion of the inner conductor 111 is placed between the caulking pieces, and the caulking piece is bent in an arc shape inward in the width direction. Then, the caulking piece is pressed so as to be wound around the exposed portion of the inner conductor 111. The caulking piece may be only on one side. The barrel only needs to have one or more caulking pieces, and the caulking pieces may be formed in other shapes. As shown in FIGS. 1 to 3, 5, and 6, the contact portion 212 extends in the depth direction. An inside of the contact portion 212 is formed with a receiving hole that opens to the back side in the depth direction, and a needle-like post of a mating contact is received in the receiving hole. Conversely, the contact portion may be formed in a needle-like post and inserted into a receiving hole similar to the receiving hole of the counterpart contact. The contactor 210 has at least a part of the outer edge inside the outer edge of the extended portion 101 when viewed in the extending direction of the inner conductor 111, that is, in the depth direction. In the case of this embodiment, as shown in FIG. 3, the contactor 210 is configured such that the entire outer edge enters the inside of the outer edge of the extension portion 101 in the extending direction of the inner conductor 111, that is, the depth direction. Yes. Accordingly, the contact 210 is completely included in the extension portion 101 in the extending direction of the inner conductor 111, that is, in the depth direction. However, it suffices that at least a part of the outer edge of the contactor is inside the outer edge of the extended portion as viewed in the direction in which the inner conductor extends. FIG. 26 and FIG. 27 show an example of the contact 210 in which a part of the outer edge of the contact is inside the outer edge of the extended portion as viewed in the direction in which the inner conductor extends. In this modified example, the contact portion 210 of the contactor 210 protrudes from the middle portion in the thickness direction to both outer sides in the width direction until it exceeds the outer edge of the extension portion 101 in the width direction. A horizontal piece 212a is provided. In this case, when viewed in the direction in which the inner conductor 111 extends, the outer edge of the portion excluding the horizontal piece 212 a that is a part of the outer edge of the contactor 210 enters the outer edge of the extension portion 101. The tip of the horizontal piece 212a, which is the remaining part of the outer edge of the contactor 210, protrudes to the outside of the outer edge of the expansion part 101. As another example, there is another modification in which the horizontal piece protrudes in the thickness direction or the other direction, in which case the horizontal piece protrudes in the direction until the outer edge of the extension portion is exceeded. Become.

  The housing 220 is made of an insulating material. As shown in FIGS. 7 to 10, the housing 220 has a first storage chamber 221 and a second storage chamber inside in order in the direction in which the internal conductor extends, that is, in order from the front to the back in the depth direction. 222 and the communication hole 223 are formed in a cylindrical shape. The first storage chamber 221 has a shape corresponding to the extension portion 101 and a shape through which the contact can pass, and is configured to receive the extension portion 101 when the extension portion 101 is inserted. It is configured. In the case of this embodiment, since all of the outer edges of the contactor 210 are located inside the outer edge of the extension portion 101 when viewed in the direction in which the inner conductor 111 extends, the first storage chamber 221 has the extension space. By being formed in a shape corresponding to the portion 101, the contactor 210 is automatically formed in a shape that can pass through. On the other hand, when a part of the outer edge of the contact is inside the outer edge of the extension portion as viewed in the direction in which the inner conductor extends, conversely, in the direction in which the inner conductor extends. The remainder of the outer edge of the contact protrudes outside the outer edge of the extension. Therefore, the first storage chamber is formed in a shape corresponding to the extended portion, and is further expanded to include a shape corresponding to the remaining portion in the extending direction of the internal conductor. The child is formed in a shape that allows passage. An example of the housing 220 corresponding to a modified example of the contactor 210 provided with the horizontal piece 212a is shown as a modified example in FIG. In this modification, a lateral groove 221a that is recessed outward from both the widthwise direction from the middle portion in the thickness direction of the first storage chamber 221 and the second storage chamber 222 of the housing 220 is formed in the housing 220. It is provided continuously from the end on the near side in the depth direction toward the back. The lateral groove 221a is provided in a shape corresponding to the lateral piece 212a of the contact portion 212 when viewed in the direction in which the inner conductor 111 extends. However, the lateral groove 221a is sufficiently more in the thickness direction and the width direction than the lateral piece 212a. It is preferable to provide a large shape with a margin. In this case, the first storage chamber 221 is formed in a shape corresponding to the extended portion 101 and further expanded to include a shape corresponding to the horizontal piece 212a as the remaining portion when viewed in the extending direction of the internal conductor 111. In this way, the contact is formed in a shape that allows the contact to pass therethrough. In the case of the other modification in which the horizontal piece protrudes in the thickness direction or the other direction, the horizontal groove is also recessed in the corresponding direction. Further, in the case of this embodiment, the first storage chamber 221 is formed with a margin with respect to the shape matching the expansion portion 101, and when the expansion portion 101 is inserted into the first storage chamber 221. In addition, a gap is formed between the outer peripheral surface of the extension portion 101 and the inner wall forming the first storage chamber 221. However, the first storage chamber 221 is formed with little margin with respect to the shape that matches the expansion portion 101, and the gap when the expansion portion 101 is inserted into the first storage chamber 221 is further reduced. The expansion part 101 may be configured to fit into the first storage chamber 221. The second storage chamber 222 is formed in a shape corresponding to the contact 210, and is configured such that the contact 210 is fitted when the contact 210 is inserted. The communication hole 223 is formed so as to communicate the second storage chamber 222 to the outside opposite to the first storage chamber 221, that is, to the outside in the depth direction.

  A locking part 224 is provided on the inner wall of the housing 220 forming the second storage chamber 222, and a locking part 213 is provided on the contactor 210, and these are locked to each other. Has been. In the case of this embodiment, as shown in FIGS. 7, 10, and 11 to 15, the direction in which the inner conductor 111 extends, that is, the direction in which the inner conductor 111 extends on the inner wall forming the second housing chamber 222 of the housing 220. A flexible piece extending in the depth direction and having flexibility is provided, and the locking portion 224 is configured by the flexible piece. A protrusion 224a is provided at the tip of the flexible piece so as to protrude toward the second storage chamber 222 along the thickness direction. As shown in FIGS. 1, 3, 5, and 11 to 15, in the contactor 210, the contactor 210 is inserted into the second storage chamber 222 on one side in the thickness direction. A convex portion on which the engaging portion 224 made of the flexible piece is hooked is provided at a portion of the housing 220 facing the engaging portion 224, and the engaging portion 213 is configured by the convex portion. Yes. Therefore, when the contactor 210 is inserted into the second storage chamber 222, the locking part 213 of the contactor 210 causes the protrusion 224a of the locking part 224 of the housing 220 to extend from the near side in the depth direction. When the protrusion 224a of the locking portion 224 of the housing 220 is hooked on the front side in the depth direction of the locking portion 213 of the contactor 210, the locking portions 224 and 213 are locked to each other. Is configured to do. A concave portion may be provided in place of the convex portion. In such a case, the protrusion 224a of the locking portion 224 of the housing 220 is fitted into the locking portion 213 of the contactor 210 so that the locking portion 224 is engaged. 213 are configured to lock together. As a modification, the contactor is provided with a flexible piece extending in the extending direction of the inner conductor, that is, in the depth direction and having flexibility, and serves as the locking portion of the contactor. A convex portion or a concave portion on which the flexible piece hangs may be provided on the inner wall forming the second storage chamber, and the locking portion of the housing may be used.

  Then, as shown in FIGS. 11 and 13, the contact start of the end surface 102 of the extended portion 101 of the processed wire 100, that is, the end surface 102 on the back side in the depth direction, and the locking portion 213 of the contactor 210 is started. An end 225 on the side opposite to the second storage chamber on the inner wall forming the first storage chamber 221 of the housing 220, that is, the front side in the depth direction, and the locking portion of the housing 220 with respect to the distance L1 from the point. The distance L2 from the contact start point of 224 is longer. Here, the contact start point of the locking portion 213 of the contactor 210 and the contact start point of the locking portion 224 of the housing 220 are determined by the contactor 210 and the first receiving chamber 221 of the housing 220 and This is the first contact portion of the two locking portions 213 and 224 when inserted into the second storage chamber 222. In the case of this embodiment, the contact start point of the locking portion 213 of the contactor 210 is formed on the back side in the depth direction of the convex portion constituting the locking portion 213, and the locking of the housing 220 is performed. The contact start point of the portion 224 is formed on the near side in the depth direction of the protrusion 224a of the locking portion 224.

  Therefore, in the case of the first embodiment, the contactor 210 connected to the inner conductor 111 is inserted into the first accommodating chamber 221 of the housing 220 as shown in order in FIGS. 11, 12, and 14. Then, the contact 210 is accommodated in the second housing chamber 222, and the locking portions 224 and 213 of the housing 220 and the contact 210 are locked. Further, the expansion part 101 is accommodated in the first storage chamber 221. In that case, since the distance L2 is longer than the distance L1, before the locking portions 224 and 213 of the housing 220 and the contactor 210 start to be locked, that is, the locking of the contactor 210. Before the contact start point of the part 213 contacts the contact start point of the locking part 224 of the housing 220 and the contactor 210 receives a force from the locking part 224 of the housing 220, the extension part 101 begins to enter the first housing chamber 221 of the housing 220, and thereafter, the expansion portion 101 advances while being guided by the inner wall forming the first housing chamber 221 of the housing 220. For this reason, for example, there is a reduced possibility that the contact 210 is displaced from the original insertion track or tilted from the original insertion track, and is inserted by twisting, and the contact 210 is provided on the inner wall forming the second storage chamber 222. In addition, for example, the engagement portion 224 such as a flexible piece, a convex portion, or a concave portion is less likely to be hooked or caught more than the original hooking method, and the insertion force is less than the contact 210 in the inner conductor 111. It is difficult to cause a problem that the connecting portion 111a breaks due to concentrated action on the connecting portion 111a.
