Description

  The present invention is suitable in the technical field of connecting a core wire such as a coaxial cable or an insulated cable and a connector.

  As signal wiring between electronic devices such as portable terminals, it is composed of a multicore cable in which a plurality of core wires are bundled as one cable, and a connector connected to one or both ends of the multicore cable. Cable assemblies are known.

  As such a cable assembly, a cable assembly that is fixed to the ground in a state in which the periphery of a shield layer covering a plurality of core wires is tightened with a metal clamp (crimped state) has been proposed (see Patent Document 1). This metal clamp is generally used when connecting a multi-core cable to a connector.

JP 2010-33996 A

  By the way, with the recent miniaturization of electronic devices, the diameter of coaxial cables and the thickness of shield layers have been reduced. When such a shield layer is tightened by a metal clamp, a pressing force continues to be applied to the shield layer, so that the shield layer tends to be damaged and the durability tends to be inferior. It has become.

  Then, an object of this invention is to provide the cable assembly which can improve durability.

  In order to solve the above problems, the present invention provides a cable assembly including a multicore cable and a connector connected to at least one end of the multicore cable, wherein the multicore cable includes a plurality of core wires and the plurality of core wires. A shield layer covering a core wire; and a sheath covering the shield layer, wherein the connector is disposed on one surface of a connector board, the shield pad to which the shield layer is soldered, and the one surface, the core wire. And a signal pad to be connected.

  In such a cable assembly, since the shield layer is soldered to one surface of the connector substrate, it is possible to avoid fixing the shield layer in a state in which a pressing force is continuously applied to the shield layer, like a metal clamp. Therefore, even if the shield layer is thin, it can be fixed in a state in which the shield layer is not easily damaged, and as a result, durability can be improved. In addition, the surface to which the shield layer and the core wire in the multicore cable are soldered is the same side of the connector board. Therefore, it becomes easy to solder the shield layer before soldering the core wire. For this reason, compared with the case where the shield layer is not soldered before soldering the core wire, the degree of movement of the core wire section from the shield layer to the tip of the core wire is reduced, and the core wire is placed at a predetermined soldering position. Positioning can be facilitated, and accurate soldering is possible. As a result, it is possible to prevent poor connection and improve the durability in an auxiliary manner. Further, since the shield layer and the core wire in the multi-core cable are both soldered on the same surface of the connector substrate, the cable assembly can be reduced in thickness.

  The plurality of core wires include at least one coaxial cable and an insulated cable, and the wire of the insulated cable is soldered to the shield pad from a portion soldered to the signal pad. The section of the insulated cable to the shield layer is more than the section of the coaxial cable from the portion where the central conductor of the coaxial cable is soldered to the signal pad to the shield layer soldered to the shield pad. It is preferable to be in a bent state.

  In such a state, when a load is applied in the direction in which the cable is pulled, the load is applied to the coaxial cable that is not bent more than the insulated cable. In general, a coaxial cable has a multi-layer structure, etc., compared to an insulated cable. Therefore, its strength is higher than that of an insulated cable. Therefore, compared to the case where the coaxial cable is bent more than equivalent to the insulated cable, it is possible to greatly reduce the occurrence of cracks and cuts in the insulated cable due to the load applied in the direction of pulling the cable. The durability can be further improved.

  Moreover, it is preferable to provide a ground pad on one surface of the connector board to which an outer conductor of the coaxial cable is soldered.

  With such a connector board, not only the central conductor of the coaxial cable but also the outer conductor is soldered to the pad, so that the coaxial cable comes off the pad due to the load applied in the pulling direction with respect to the coaxial cable. Can be suppressed. Therefore, it is possible to further suppress cracks, cuts, and the like that occur in the insulated cable having a strength lower than that of the coaxial cable.

  The section of the coaxial cable is preferably arranged along the longitudinal direction of the shield layer soldered to the shield pad.

  In such an arrangement state, the section of the coaxial cable is almost straight, so that when the load is applied in the direction of pulling the section compared to when the section is bent, Load concentration can be suppressed. For this reason, it is possible to further prevent the coaxial cable from being detached from the pad due to the load applied in the pulling direction with respect to the coaxial cable. As a result, the coaxial cable can be further prevented from cracking, cutting, and the like that occur in the insulated cable having a strength lower than that of the coaxial cable.

  The signal pad is preferably electrically connected to another connector member.

  According to such a cable assembly, the connector board can be used as a relay board. For example, the direction of the connection end of the connector with respect to the connector board can be changed.

  As described above, according to the present invention, a cable assembly capable of improving durability is provided.

  FIG. 5 is a top view showing a state of connection between the pad and the multicore cable. As shown in FIG. 5, at least one end of the above-described multi-core cable 10 is led out. That is, the shield layer 72 is exposed from the end of the multi-core cable to be connected to the connector main body 30, and the plurality of coaxial cables 50 and the insulated cables 60 are respectively exposed from the shield layer 72. For each coaxial cable 50, the outer conductor 53 is exposed from the sheath 54, the insulating layer 52 is exposed from the outer conductor 53, and the central conductor 51 is exposed from the insulating layer 52, and the electric wire 61 is connected from the insulating layer 62 to each insulating cable 60. Exposed.

  The shield layer 72 in the exposed state is soldered to the shield pad 35 on the one surface OS of the connector substrate 32. In the present embodiment, the shield layer 72 is disposed on the rectangular conductor C3, and is electrically and mechanically connected to the rectangular conductor C3 by solder S.

  On the other hand, the outer conductor 53 of each coaxial cable 50 in an exposed state is soldered to the ground pad 34 on the one surface OS of the connector substrate 32. In the case of this embodiment, each outer conductor 53 is arranged on the rod-shaped conductor C2 in parallel with each other in a state perpendicular to the longitudinal direction of the rod-shaped conductor C2, and is electrically and mechanically connected to the rod-shaped conductor C2 by solder S. Connected.

  Further, the central conductor 51 of each coaxial cable 50 in an exposed state is soldered to the signal pad 33 on the one surface OS of the connector board 32. In the case of the present embodiment, among the rod-shaped conductors C1, four rod-shaped conductors C1 in the central portion are the connection targets of the center conductor 51. One end of each central conductor 51 is disposed on one end of the rod-shaped conductor C1 opposite to the arrangement area AR, and is electrically and mechanically connected to the rod-shaped conductor C1 by solder S. As a result, the central conductor 51 and the signal conductor 42 </ b> A in the connector terminal 42 (FIG. 4) are electrically connected through the signal pad 33.

  On the other hand, the electric wire 61 of each insulated cable 60 in the exposed state is soldered to the signal pad 33 on the entire surface OS of the connector substrate 32. In the case of the present embodiment, among the rod-shaped conductors C1, the rod-shaped conductors C1 other than the four rod-shaped conductors C1 in the central portion are the connection targets of the electric wires 61. One end of each electric wire 61 is arranged on one end of the rod-shaped conductor C1 opposite to the arrangement area AR, and is electrically and mechanically connected to the rod-shaped conductor C1 by solder S. Thereby, the electric wire 61 and the signal conducting wire 42 </ b> A in the connector terminal 42 are electrically connected through the signal pad 33.

  FIG. 6 is a schematic diagram for explaining the difference between the bending amount of the coaxial cable and the bending amount of the insulated cable. As shown in FIG. 6, the section SC <b> 1 of the insulated cable 60 is bent (bent) than the section SC <b> 2 of the coaxial cable 50.

  Specifically, the section SC1 of the insulated cable 60 is a section from a portion where the electric wire 61 is soldered to the shield layer 72 soldered to the shield pad 35, and is indicated by a solid line in FIG. Part. On the other hand, the section SC2 of the coaxial cable 50 is specifically a section from a portion where the center conductor 51 is soldered to the shield layer 72 soldered to the shield pad 35, and is indicated by a solid line in FIG. It is a part that has been.

  In the present embodiment, the section SC2 of the coaxial cable 50 is disposed along the longitudinal direction of the shield layer 72 soldered to the shield pad 35, and is generally in a straight state. Therefore, in the present embodiment, the length L1 of the section SC1 of the insulated cable 60 is larger than the length L2 of the section SC2 of the coaxial cable 50.

  In addition, as a method of making the section SC1 of the insulated cable 60 bend more than the section SC2 of the coaxial cable 50, for example, the coaxial cable 50 and the insulated cable 60 out of the shield layer 72 by the same length are coaxial. A method of soldering these cables to the respective pads after cutting only the tip portion of the cable 50 by a predetermined length can be mentioned.

  In the cable assembly 1 according to the above-described embodiment, since the shield layer 72 is soldered to the one surface OS of the connector substrate 32, the pressing force is continuously applied to the shield layer 72 as in the metal clamp of the above-mentioned Patent Document 1. It is possible to avoid fixing in a fixed state. Therefore, even if it is the tape-shaped shield layer 72, it becomes possible to ground in the state where the shield layer 72 is hard to be damaged, and as a result, durability can be improved.

  Note that the center conductor 51 and the outer conductor 53 of the coaxial cable 50 in the multicore cable 10 and the electric wire 61 of the insulated cable 60 are both soldered on the same surface OS of the connector substrate 32. Therefore, it is easy to solder the outer conductor 53 and the shield layer 72 before the center conductor 51 and the electric wire 61 are soldered. For this reason, compared with the case where the outer conductor 53 and the shield layer 72 are not soldered before the center conductor 51 and the electric wire 61 are soldered, the movement amount of the section from the shield layer 72 to the outer conductor 53 or the shield layer 72 is reduced. Can be reduced. Therefore, the central conductor 51 and the electric wire 61 can be easily positioned at a predetermined soldering position, and accurate soldering can be performed. As a result, it is possible to prevent poor connection and improve the durability in an auxiliary manner. Further, since the center conductor 51 and the outer conductor 53 of the coaxial cable 50 in the multicore cable 10 and the electric wire 61 of the insulated cable 60 are both soldered on the same surface OS of the connector substrate 32, the cable assembly 1 is thin. It can also be converted.

  By the way, the shield layer 72 and the coaxial cable 50 and the insulated cable 60 covered by the shield layer 72 are not mechanically connected to each other. For this reason, when the multi-core cable 10 is pulled in the longitudinal direction, even if the shield layer 72 is fixed to the shield pad 35 of the connector substrate 32, the coaxial cable 50 or the insulation covered with the shield layer 72 is insulated. A load may be applied to the cable 60 in the pulling direction. In such a case, since the strength of the insulated cable 60 is weaker than that of the coaxial cable 50, cracks, cuts, and the like due to the load applied in the pulling direction are more likely to occur in the insulated cable 60 than the coaxial cable 50.

  However, in the cable assembly 1 of the present embodiment, the section SC1 (FIG. 6) of the insulated cable 60 is connected to each pad in a state of being bent more than the section SC2 (FIG. 6) of the coaxial cable 50. For this reason, the coaxial cable 50 can protect the insulated cable 60 in a state in which it is difficult to apply a load to the insulated cable 60, and can prevent the load from being applied in the pulling direction with respect to the insulated cable 60. Therefore, it is possible to greatly reduce the occurrence of cracks or cuts in the insulated cable 60 due to the load applied in the pulling direction, and the durability can be further improved.

  Further, since the outer conductor 53 of the coaxial cable 50 is soldered to the ground pad 34, the coaxial cable 50 is detached from the pad due to a load applied to the coaxial cable 50 in the pulling direction. Can be suppressed. Therefore, the coaxial cable 50 can further suppress cracks, cuts, and the like that occur in the insulated cable 60 having a lower strength than the coaxial cable 50.

  Further, in the case of the present embodiment, the section SC2 (FIG. 6) of the coaxial cable 50 is disposed along the longitudinal direction of the shield layer 72 soldered to the shield pad 35, and the section SC2 is generally straight. It has become. For this reason, compared with the case where the section SC2 of the coaxial cable 50 is in a bent state, when a load is applied in a direction in which the section SC2 is pulled, concentration of the load can be suppressed. Therefore, it is possible to further prevent the coaxial cable 50 from being detached from the pad due to the load applied in the pulling direction with respect to the coaxial cable 50. As a result, the coaxial cable 50 can further suppress cracks, cuts, and the like that occur in the insulated cable having a strength lower than that of the coaxial cable 50.

One end of the rod-shaped conductor C11 is disposed on one surface of the covering portion PA1 spaced apart from the rod-shaped member C2 of the ground pad 34, and the other end is disposed on an end portion of one surface of the exposed portion PA2.

  Among the rod-shaped conductors C11, the four rod-shaped conductors C11 in the central portion are the connection targets of the center conductor 51. One end of each central conductor 51 is disposed on one end of the four rod-shaped conductors C11 on the covering portion side, and is electrically and mechanically connected to the rod-shaped conductor C11 by solder S.

That is, the section of the insulated cable 60 from the portion where the wire 61 is soldered to the shield layer 72 soldered to the shield pad 35 is soldered to the shield pad 35 from the portion where the central conductor 51 is soldered. It is in a state of being bent more than the section of the coaxial cable 50 up to the shield layer 72.

  On the other hand, the ground pattern 37 is disposed on the other surface of the connector substrate 82A that is opposite to the one surface OS of the connector substrate 82A across the covering portion PA1 and the exposed portion PA2.

The external conductor 53 is connected to the ground pad 34 in the same state as in the first embodiment, and the shield layer 72 is connected to the shield pad 35 in the same state as in the first embodiment.

The first embodiment is preferable from the viewpoint of using the connector board as a relay board and changing the direction of the connection end of the connector with respect to the connector board, for example.
