Description

  The present invention relates to a connector-equipped cable including a connector such as an RJ45 or RJ47 connector, a cable having a plurality of core wires inside such as a twisted pair cable (hereinafter abbreviated as a TP cable), and a method of manufacturing the same.

  The RJ45 connector is widely used as a communication connector in Ethernet (registered trademark) such as a LAN. A LAN cable with a connector in which an eight-core four-pair TP cable is connected to a plug of an RJ45 connector is connected to a jack provided in a data device such as a computer, a web camera, a switching hub, a wireless LAN access point, and an IP telephone. To perform signal transmission and reception between communication devices.

  As described above, the reason that the LAN cable having the RJ45 connector is widely used for transmitting and receiving signals between communication devices is that a connector and a plug can be easily obtained anywhere in the world according to a universal standard. And that a single cable includes an 8-pole 8-core signal line. Therefore, the LAN cable having the RJ45 connector has no other suitable cable, and is excellent in use as a communication cable.

  In addition, so-called PoE (Power over Ethernet), which supplies a direct current to a communication signal using the LAN cable in recent years, is becoming widespread, and power is supplied to these data devices. For PoE, specifications for transmission_GoBack_GoBack are defined by standards such as IEEE802.3af and at.

  Normally, the connection between the pins of the connector and the core wire is realized by caulking the connector with the TP cable inserted into the connector, as shown in Japanese Patent Application Laid-Open No. 2014-235902. That is, by caulking the connector into which the core wire has been inserted, the eight pins of the connector are simultaneously pushed deep into the connector, and the sharp ends at the upper ends of the respective pins are pierced into the core wire of the TP cable, thereby reducing the electric wire. The core wire and the pin are crimped (see Patent Document 2, FIGS. 7 and 8).

  When this LAN cable is used as a signal line or a PoE transmission line, a poor contact between the cable and the connector becomes a problem, as disclosed in Patent Document 1.

The connector of Patent Literature 1 includes an electric wire connection portion for connecting to a core wire above the terminal, and the electric wire connection portion is formed in a U-shape in which an end portion is bifurcated and bent inward. The distance between the divided ends is smaller than the diameter of the core wire. Thus, the core wire is sandwiched between the forked ends in the width direction, and the metal wire in the core wire and the end are electrically connected.
JP 2014-235902 A

  However, in recent years, the demand for a LAN cable having a fine count of, for example, 28 to 32 AWG or more has been increasing. Particularly, when the LAN cable is used as a signal line of a communication device, the demand is great. The thin TP cable used also has a thin core wire. If the TP cable is sandwiched between terminals in the width direction of the core wire, the core wire may be cut and disconnected.

  In addition, when a LAN cable is used as a signal line of a communication device, the use of the electronic device to which the connector of the LAN cable is connected is increased. For this reason, the TP cable may be pulled in a direction away from the connector, and there is a problem that the TP cable is more likely to be disconnected.

  Therefore, a technical problem to be solved by the present invention is to provide a cable with a connector that can reduce the problem of poor connection between a terminal and a core wire, and a method for manufacturing the same.

  In the present embodiment, the connector 10 is an RJ45 connector, and has a casing 11 made of synthetic resin and eight plate-shaped terminals 30. The casing 11 has a shape having a substantially rectangular parallelepiped. As the synthetic resin constituting the casing 11, it is preferable to use a thermosetting resin, a thermoplastic resin, or the like having heat resistance higher than a heating temperature described later. In the cable with connector 1 according to the present embodiment, the casing 11 does not need to be transparent because the casing 11 does not need to visually recognize the connection between the plate terminal and the TP cable, as described later.

As shown in FIGS. 3 and 6, the outer sheath 7 of the TP cable 2 is removed at both ends of the TP cable 2 housed in the cable housing portion 13 of the connector, and the core wire pair 4 is exposed. Although the length of the exposed core wire pair 4 is not particularly limited, it is configured to be shorter than the length of the cable housing portion 13 in the front-rear direction, and the outer sheath 7 may extend to the front side of the cable support protrusion 15. preferable.

  Further, the tip of the core wire pair 4 is in a state in which the twist of the core wire 3 forming the pair is returned and straightened, and further, the outer skin 6 is removed and the metal wire 5 is exposed. The surface of the metal wire 5 from which the outer skin 6 has been removed is covered with a solder layer 18. The portion of the metal wire 5 on which the solder layer 18 is formed is referred to as a terminal connection portion 9.

  It is preferable to use a solder that can be welded at a low temperature as the solder used for the solder layer 18. Also, cream solder can be used. Further, the thickness of the solder layer 18 is not particularly limited.

  The surface of the solder layer 18 of the terminal connection portion 9 may be coated with a flux (soldering accelerator) not shown. As the flux, a known flux based on pine tar can be used.

  The length of the terminal connection portion 9 is not particularly limited, but is preferably formed to be longer than the length of the plate-like terminal 30 in the front-rear direction, as described later. Further, the tip of the terminal connection portion 9 extends forward beyond the slot 12 and reaches the front opening 16 of the casing front 11a.

That is, the terminal connection portion 9 is welded to the connection surface 30a of the plate-like terminal 30. As will be described later, by heating the terminal connection portion 9, the plate-like terminal 30 and the terminal connection portion 9 melt the solder layer 18 on the surface of the terminal connection portion 9 and are welded to the connection surface 30a.

  Next, a method for manufacturing the cable with connector 1 according to the present embodiment will be described. FIG. 7 is a flowchart illustrating a method for manufacturing the cable with connector according to the present embodiment.

  In manufacturing the cable 1 with a connector, first, the outer coating 7 on one end side of the TP cable is removed, and each core wire is extended. Thereafter, the outer cover 6 having a predetermined length is removed to expose the metal wire 5 (# 1). Thereby, the terminal connection portions 9 are formed at both ends of the TP cable 2.

  Step # 1 in FIG. 7 corresponds to a terminal connection part creation step.

  Next, a solder layer 18 is formed around the exposed metal wires 5 (# 2). The solder layer 18 can be formed, for example, by immersing the tip of the metal wire 5 in molten solder and cooling it. A flux may be applied to the surface of the solder layer 18 as needed.

  Step # 2 in FIG. 7 corresponds to a solder application step.

  In this embodiment, the solder layer 18 is provided around the metal wire 5 of the cable. However, the solder layer 18 may be applied to the connection surface 30a of the plate terminal of the connector.

  Next, the terminal connection portion 9 of the TP cable is inserted into the connector 10 (# 3). Specifically, as shown in FIG. 8, the core wires 3 are arranged in a predetermined wiring order, and if necessary, the ends of the terminal connection portions 9 are cut to align the ends of the core wires 3. 9 is inserted into the cable housing 13 through the rear opening 14 of the connector 1. As a result, the terminal connection portions 9 are arranged corresponding to the predetermined slots 12.

  If the connector 10 has a load bar, the terminal bar 9 is inserted into the cable housing 13 together with the load bar after attaching the load bar to the core wire 3.

  Subsequently, by deeply inserting the TP cable, the distal end of the terminal connection portion 9 inserted into the cable housing portion 13 projects from the front opening 16 to the outside of the casing 11 as shown in FIG. 9 (# 4). The length L (see FIG. 9) of the lead-out portion 9a of the terminal connection portion 9 drawn out of the casing 11 in a state where the TP cable is inserted most deeply is the length of the terminal connection portion 9 created in # 1 and # 2. Is determined by In addition, it is preferable that the length L of the drawer portion 9a is adapted to the specification of the heating device 40 used in the heating step described later. If the drawer portion 9a is too long, it may be cut to a predetermined length.

  Steps # 3 and # 4 in FIG. 7 correspond to a cable insertion step.

  Next, the drawer portion 9a is heated to melt the solder layer 18 of the terminal connection portion 9, and the plate terminal 30 and the terminal connection portion 9 are welded by soldering (# 5). FIG. 10 is a diagram schematically illustrating a step of heating the terminal connection portion. As shown in FIG. 10, a heating device 40 is used to heat the drawer portion 9a. As an example, the configuration shown in FIG. 10 can be adopted.

  The heating device 40 has pinches 41 and 42 that can sandwich the drawer 9a from above and below, and heats the pinches 41 and 42. For the temperature management of the pinches 41 and 42, for example, a thermocouple is preferably used.

  As shown in FIG. 11, the pinches 41 and 42 are preferably long in the width direction so that a plurality of connectors can be simultaneously held in the width direction and heated.

  FIG. 12 is a graph schematically showing the relationship between the temperature and the time in the step of heating the terminal connection portion 9. In the heating step, it is preferable to control the maximum temperature Tmax and the time T1 required to reach the maximum temperature. Specifically, the maximum temperature Tmax can be set to 180 to 260 ° C. depending on the type of solder used for the solder layer. Further, the time T1 until the temperature reaches the maximum temperature is preferably set to about 2 to 10 seconds.

  If the maximum temperature Tmax is too high, the solder layer 18 flows, causing a short circuit between the adjacent plate terminals 30 and a deformation of the casing 11. On the other hand, if Tmax is too low, the solder layer 18 may not be sufficiently melted, and the soldering between the plate-shaped terminal 30 and the terminal connection portion 9 may not be sufficiently performed.

  On the other hand, if the time T1 is too short, the melting of the solder layer 18 will be insufficient, and if the time T1 is too long, a short circuit between the adjacent plate terminals 30 or deformation of the casing 11 will be caused.

  The temperature control in the heating step can also be adjusted by the position and length of the pinch 41, 42 sandwiching the drawer 9a.

  Further, in the heating step or before the heating step, a caulking step of the connector 10 is performed, and the plate terminal 30 can be pushed into the deep side of the slot 12 as shown by an arrow 90 in FIG. Thereby, the connection surface 30a of the plate-shaped terminal 30 can be brought into close contact with the terminal connection portion 9, and soldering can be performed more reliably.

  After the terminal connection section 9 is heated to a predetermined temperature by the heating device 40, the solder is solidified by, for example, natural cooling, and the terminal connection section 9 and the plate-shaped terminal 30 are welded.

  Step # 5 in FIG. 7 corresponds to a terminal welding step.

  Next, the leading portion 9a protruding from the front opening 16 of the casing 11 is cut along the front surface 11a of the casing 11 so that the tip of the terminal connection portion 9 does not protrude from the front surface 11a of the casing 11 (# 6).

  Thereafter, if necessary, the front opening 16 is closed. The front opening 16 can be closed with a lid or a sealing material (not shown). In this case, the terminal connection portions 9 are prevented from contacting each other.

  The connector 10 is connected to the other end of the TP cable 2 by repeating the same steps as described above.

  As described above, the connector-equipped cable 1 according to the present embodiment draws the metal wire inserted into the connector from the front opening provided on the front of the connector to the outside of the connector, and heats the drawn-out portion. The solder provided around the connection portion can be melted, and the plate-shaped terminal and the terminal connection portion can be welded.

  In addition, by pulling the core wire 3 pulled out from the front opening, the terminal connection portion can be inserted deeply in the insertion direction of the connector, and the core wire can be reliably arranged corresponding to the plate-like terminal. . Therefore, the work of connecting the connector and the TP cable can be easily automated.

  Therefore, the problem of poor connection between the plate-shaped terminal and the core wire can be reduced, and no poor contact occurs even when used in a moving state.

  Note that the present invention is not limited to the above embodiment, and can be implemented in other various aspects. For example, the shape of the plate-like terminal 30 is not limited to the substantially rectangular metal plate according to the above-described embodiment. For example, the plate-like terminal 31 having terminal connection guides 32a and 32b as shown in FIGS. It may be.
