Description

  The present invention relates to a cable connector for connecting a shielded twisted pair cable to equipment.

  The differential transmission method is often adopted as a technology for realizing high-speed data communication. The outline of the differential transmission method is shown below. Although the differential transmission method is generally established with two or more transmission lines, the differential transmission method using paired lines (pair lines), which are two transmission lines, will be described below in order to facilitate the description. Indicates

  The differential transmission scheme is a scheme in which differential signals are transmitted through a pair of wires between a differential driver on the transmission side and a differential receiver on the reception side. The differential signal consists of two signals that are the same amplitude and in antiphase. The paired wires are, for example, two balanced wiring patterns formed of one pair (one pair) of conductors or two wiring patterns formed on a printed circuit board. Here, the pair wire is assumed to be a balanced cable. The differential transmission method is suitable for high-speed data transmission because the voltage amplitude per conductor is low and the rise of the signal can be shortened.

  Furthermore, the differential transmission scheme can reduce the noise radiated from the balanced cable. That is, two signals having the same amplitude and the opposite phase are individually applied to the two conductors constituting the balanced cable. Because the two signals are in antiphase, the currents flowing in the two conductors are in opposite directions. Therefore, the magnetic fields generated from the two wires cancel each other, and almost no radiation noise is generated from the balanced cable.

In addition, the differential transmission method can remove the influence of noise received from the outside. That is, in the differential transmission method, noise is equalized on the two conducting wires, so that noise is canceled when the signal is difference on the receiving side.
For these reasons, the differential transmission scheme is often used for high-speed data communication.

On the other hand, in recent years, the differential transmission method has been increasingly used in an environment with much electromagnetic noise, such as in a factory or in a vehicle.
In a general differential transmission system, a twisted pair cable is often used. The twisted pair cable is a cable in which insulated wires (core wires) are twisted and paired. The insulated wire is obtained by coating a conducting wire with an insulator. This twisted pair cable is widely used because it is inexpensive and easy to bend, and has a higher degree of earth balance than other paired cables.
On the other hand, in a differential transmission system in an environment with a large amount of electromagnetic noise, a shielded twisted pair cable is used in order to isolate electromagnetically from the outside and to suppress electromagnetic interference radiation from the cable. A shielded twisted pair cable is a cable with a shield attached to the outside of the twisted pair cable.

  The shielded twisted pair cable is comprised of a twisted pair cable, a shielding outer conductor (outer conductor sheath) and resin interposition. The outer conductor sheath is a member that covers the outer periphery of the twisted pair cable. The resin interposition is a member for holding the structure of the shielded twisted pair cable. In this shielded twisted pair cable, a differential transmission system of devices such as communication devices is connected to the twisted pair cable, and an outer conductor sheath is connected to the ground, thereby forming a shield structure that wraps the differential transmission system in the ground.

  Further, the earth balance is a parameter representing a signal conversion ratio between the differential mode and the common mode. The differential mode is a mode that is established in differential transmission circuits. Also, the common mode is a mode that is established by a path including the differential transmission circuit, the external ground, and its parasitic capacitance. The differential transmission circuit is composed of a pair cable and a transceiver.

The degree of ground balance depends in large part on the electrical characteristics of the cable. That is, the degree of earth balance becomes a bad value when the difference between the electrical characteristics of the two wires forming the paired cable is large, and mutual mode conversion tends to occur. On the other hand, the degree of earth balance becomes a good value when the difference between the electrical characteristics of the two conductors is small, and mutual mode conversion hardly occurs.
In the twisted pair cable, the differences in the electrical characteristics of the two wires are averaged by twisting the two wires together, so that the ground balance can be maintained at a good value.

  Also, the degree of earth balance has a meaning as an index for suppressing the occurrence of noise. For example, in the differential mode used in the differential transmission system, the signal converted into the common mode is a component that does not contribute to transmission of the differential signal, and acts as common mode noise for the differential transmission circuit. Therefore, in order to suppress the occurrence of common mode noise in a differential transmission circuit, it is necessary to create a differential transmission system that is difficult to convert from differential mode to common mode, in other words, a cable with good balance to ground should be used. The conclusion is obtained.

  From the above, in order to reduce the influence of common mode noise in a differential transmission circuit, is it possible to suppress the propagation of common mode noise itself or improve the ground balance so that common mode noise is less likely to occur? Squeezed to either.

  The twisted pair cable has a structure in which common mode noise is less likely to occur by improving the ground balance. Further, in addition to the above-described effect of the twisted pair cable, the shielded twisted pair cable has a structure in which common mode noise is not propagated inside the cable by the outer conductor sheath. Thus, the shielded twisted pair cable can realize both high ground balance and shielding from the external environment.

  On the other hand, when a shielded twisted pair cable is connected to the device, the above effect can not be maintained unless a connector made for the shielded twisted pair cable is used. The connector for the shielded twisted pair cable is provided not only with the connector pins for connecting the core wires, but also with a structure for connecting by meshing the metal case and the outer conductor sheath connected to the ground. With this structure, the connector for the shielded twisted pair cable can be properly terminated.

However, when connecting a shielded twisted pair cable to a device, there are cases where the connector for the shielded twisted pair cable can not be used as specified. For example, in an industrial apparatus which often connects a large number of signal lines, one signal line is connected to transmit various signals from analog signals to high-speed digital signals between a plurality of apparatuses having different functions. May be aggregated into connectors.
In addition, if the size of the connector is determined in advance and it is necessary to connect a thin cable to the connector, even if the core of the cable can be connected to the connector pin, the metal case and the outer conductor sheath May not engage.

Even in such a case, as a method for realizing the connection of the outer conductor sheath to the ground, the following method may be mentioned.
The first method is a method in which the outer conductor sheath is processed into a pigtail shape, and the pigtail is directly extended and grounded to the ground of the device.
The second method is a method in which the outer conductor sheath is processed into a pigtail shape, the pigtail is connected to a metal case provided in the connector, and is connected to the ground through the metal case.
The third method is a method of processing the outer conductor sheath into a pigtail shape, providing a connector pin at the end of the pigtail, and connecting it to the ground possessed by the device through the connector pin when the connector is connected to the device.

  However, the cross-sectional shape of the portion where the pigtail extends is different from the shape of the shielded twisted pair cable. Therefore, depending on the arrangement of the two core wires and the pigtail in the cross-sectional direction, the condition that the difference between the electrical characteristics of the two wires is small may not be satisfied, and the degree of balance to ground may be deteriorated. And, when the degree of earth balance becomes worse, mutual mode conversion tends to occur, leading to deterioration of the noise resistance of the entire equipment using the cable.

  On the other hand, an electrical connector for the purpose of noise suppression of a twisted pair cable is known (see, for example, Patent Document 1). In Patent Document 1, there is shown an electrical connector which has a housing to which a pigtail is connected, and the housing contacts the information transmitting / receiving device casing to ground the pigtail. Further, Patent Document 1 shows an electrical connector having a connector pin to which a pigtail is connected, and fitting the connector pin to a contact pin provided in an information transmitting / receiving device housing to ground the pigtail. .

International Publication No. 2012/070150

  However, Patent Document 1 does not particularly mention the positional relationship between the core wire of the twisted pair cable and the pigtail, and the electrical connector disclosed in Patent Document 1 has a problem that the balance of the twisted pair cable can not be improved. .

  The present invention has been made to solve the problems as described above, and it is an object of the present invention to provide a cable connector capable of improving the ground balance of a shielded twisted pair cable.

  A cable connector according to the present invention includes a jig mechanism through which a plurality of core wires and one or more pigtails of a shielded twisted pair cable are passed, and a connector mechanism to which a core wire passing through the jig mechanism and a pigtail are connected. The jig mechanism is formed on a flat insulator and a plurality of core wire through holes formed on the insulator and having a diameter larger than the outer diameter of the core wire, and formed on the insulator, and the diameter is larger than the pigtail outer diameter. And one or more pigtail through holes disposed equidistantly to the core wire through holes.

  According to this invention, since it comprised as mentioned above, it becomes possible to improve the ground balance degree of a shielded twisted pair cable.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Embodiment 1
FIG. 1 is a perspective view showing a configuration example of a cable connector 1 according to Embodiment 1 of the present invention.
The cable connector 1 is a structure for mounting the shielded twisted pair cable 2 on a device.
As shown in FIG. 5, the shielded twisted pair cable 2 is composed of a core wire 21, an outer conductor sheath 22, one or more pigtails 23, an insulating coating 24, and resin interposition (not shown). The core wire 21 is an insulated wire in which a conducting wire is covered with an insulator, and a plurality of core wires 21 are twisted to form a twisted pair cable. The outer conductor sheath 22 is a member that covers the outer periphery of the twisted pair cable. The pigtail 23 is formed by processing a part of the outer conductor sheath 22 into a pigtail shape. The insulating coating 24 is a coating that covers the outer conductor sheath 22. The resin interposition is a member for holding the structure of the shielded twisted pair cable 2. The shielded twisted pair cable 2 shown in FIG. 5 has two core wires 21 and one pigtail 23.

As shown in FIG. 1, the cable connector 1 includes a jig mechanism 11 and a connector mechanism 12.
The jig mechanism 11 is a mechanism for defining the positional relationship between the core wire 21 and the pigtail 23 by passing the core wire 21 and the pigtail 23 of the shielded twisted pair cable 2 through.
The connector mechanism 12 is a mechanism to which the core wire 21 and the pigtail 23 passed through the jig mechanism 11 are connected.

Next, a configuration example of the jig mechanism 11 will be described with reference to FIG.
The jig mechanism 11 is constituted by a flat insulator 111 as shown in FIG. In FIG. 2, the insulator 111 is configured in a cylindrical shape.

  Further, in the insulator 111, two through holes (core wire through holes) 112 through which the core wire 21 passes are formed in the axial direction. The diameter of the through hole 112 is larger than the outer diameter of the core 21 of the shielded twisted pair cable 2 to be mounted. Although two through holes 112 are formed in FIG. 2, the number of through holes 112 may be the number corresponding to the number of core wires 21 of the shielded twisted pair cable 2 to be attached.

  Further, in the insulator 111, one through hole (pigtail through hole) 113 through which the pigtail 23 passes is formed in the axial direction. The diameter of the through hole 113 is larger than the outer diameter of the pigtail 23 of the shielded twisted pair cable 2 to be mounted. Further, in FIG. 2, the through hole 113 is disposed in parallel (including a substantially parallel meaning) to the through hole 112. Although one through hole 113 is formed in FIG. 2, the number of through holes 113 may be the number corresponding to the number of pigtails 23 of the shielded twisted pair cable 2 to be attached.

  In the plane perpendicular to the axial direction of the insulator 111, the positions of the through holes 113 are equal to the positions of the through holes 112. In FIG. 2B, since the positions on the alternate long and short dash lines are positions equidistant from the positions of the through holes 112, the through holes 113 are disposed on the alternate long and short dash lines.

Next, a configuration example of the connector mechanism 12 will be described with reference to FIG.
The connector mechanism 12 has the metal housing 121 which is a housing | casing in which one surface was open | released, as shown in FIG.

In the metal housing 121, an opening 122 is formed on the surface facing the one surface (open surface). The diameter of the opening 122 is larger than the outer diameter of the jig mechanism 11 (insulator 111).
In addition, the metal housing 121 may be comprised from a single member, and as shown in FIG. 4, may be comprised from two members (upper side cover 1211 and lower side cover 1212). When the metal housing 121 is composed of two members, the upper cover 1211 and the lower cover 1212 are fixed by screws or the like to constitute the metal housing 121. In FIG. 4, illustration of a fixed portion of the metal housing 121 by a screw or the like is omitted.

Further, the metal housing 121 is provided on the open surface with a resin member 124 in which a plurality of connector pins 123 to which the core wire 21 is connected is included.
Further, a hole 125 is formed in one side surface of the metal housing 121. The hole 125 is a portion for connecting the pigtail 23 to the metal housing 121 by fixing the end of the pigtail 23 drawn into the connector mechanism 12 through the opening 122 with a screw or the like. By providing the hole 125 near the opening 122, the pigtail 23 drawn into the connector mechanism 12 through the opening 122 can be conducted to the metal housing 121 without being pulled around in the connector mechanism 12. It is.

Next, a method for attaching the cable connector 1 according to the first embodiment to the shielded twisted pair cable 2 will be described with reference to FIG. In FIG. 5, the case where the metal housing 121 consists of a single member is shown.
The operator first untwists the one-to-two core wires 21 of the shielded twisted pair cable 2. Thereafter, the worker passes the untwisted core wire 21 through the through hole 112 of the jig mechanism 11 before attaching the connector mechanism 12 to the shielded twisted pair cable 2. At this time, the worker passes one core wire 21 through one through hole 112. Further, the worker passes the pigtail 23 of the shielded twisted pair cable 2 through the through hole 113 of the jig mechanism 11. Thereafter, the worker inserts the jig mechanism 11 into the opening 122 of the metal housing 121. Thereafter, the worker connects the core wire 21 passed through the through hole 112 to the connector pin 123 contained in the resin member 124. Further, the worker connects the pigtail 23 passing through the through hole 113 to the metal housing 121 by fixing the pigtail 23 to the hole 125 in the metal housing 121 with a screw or the like. Thereafter, the worker attaches the metal housing 121 to the resin member 124.

Next, a method of attaching the cable connector 1 to the shielded twisted pair cable 2 in the case where the metal housing 121 is composed of two members will be described.
The operator first untwists the one-to-two core wires 21 of the shielded twisted pair cable 2. Thereafter, the worker passes the untwisted core wire 21 through the through hole 112 of the jig mechanism 11 before attaching the connector mechanism 12 to the shielded twisted pair cable 2. At this time, the worker passes one core wire 21 through one through hole 112. Further, the worker passes the pigtail 23 of the shielded twisted pair cable 2 through the through hole 113 of the jig mechanism 11. Thereafter, the worker connects the core wire 21 passed through the through hole 112 to the connector pin 123 contained in the resin member 124. In addition, the operator connects the pigtail 23 passing through the through hole 113 to the metal housing 121 by fixing it to the hole 125 in the connector mechanism 12 with a screw or the like. Thereafter, the worker sandwiches the jig mechanism 11 and the resin member 124 with the upper cover 1211 and the lower cover 1212 and fixes the upper cover 1211 and the lower cover 1212 with a screw or the like.
The connector mechanism 12 may be configured to simultaneously connect the pigtail 23 to the metal housing 121 by using a screw or the like for fixing the upper cover 1211 and the lower cover 1212.

  As described above, the core wire 21 is connected to the connector pin 123 while the positional relationship between the core wire 21 and the pigtail 23 is fixed at the end portion of the cable where the arrangement of the core wire 21 and the pigtail 23 is easily disturbed by the jig mechanism 11 The pigtail 23 can be connected to the metal housing 121. At this time, the positions of the core wires 21 and the pigtails 23 are fixed so as to be symmetrical. As a result, it is possible to suppress the difference in the electrical characteristics of the two wires due to the arrangement of the core wire 21 and the pigtail 23, which leads to the improvement of the ground balance. Therefore, mutual mode conversion hardly occurs in the shielded twisted pair cable 2, and the propagation of common mode noise can be suppressed.

  The jig mechanism 11 may be fixed to the connector mechanism 12 with an adhesive or the like, or may be detachable.

Further, the configuration of the jig mechanism 11 is not limited to the configuration shown in FIG. 2, and may be, for example, the configuration shown in FIG.
The jig mechanism 11 shown in FIG. 6 differs from the configuration shown in FIG. 2 in that the through hole 113 is disposed obliquely to the through hole 112. That is, the through hole 113 is disposed at a position close to the through hole 112 as shown in FIG. 6B at one end face (symbol A shown in FIG. 6A) in the insulator 111. On the other hand, in the other end face (symbol B shown in FIG. 6A) of the insulator 111, the through hole 113 is disposed at a position distant from the through hole 112 as shown in FIG. 6C.

  As described above, in the jig mechanism 11 shown in FIG. 6, the through holes 113 are arranged obliquely with respect to the through holes 112, whereby the positions of the through holes 113 are equidistant from the positions of the through holes 112. , And the pigtails 23 can be guided to places separated from the respective core wires 21. As a result, in the cable connector 1 using the jig mechanism 11 shown in FIG. 6, the arrangement in which the core wire 21 and the pigtail 23 are difficult to approach in the connector mechanism 12 can be realized, and the electricity resulting from the arrangement of the core wire 21 and the pigtail 23 It is possible to further reduce the difference in the dynamic characteristics.

  As described above, according to the first embodiment, the cable connector 1 includes the plurality of core wires 21 of the shielded twisted pair cable 2 and the jig mechanism 11 through which one or more pigtails 23 pass, and a jig mechanism 11. The connector mechanism 12 is connected to the core wire 21 and the pigtail 23 passed through 11, and the jig mechanism 11 is formed on the flat insulator 111 and the insulator 111 and has a diameter larger than the outer diameter of the core wire 21. A plurality of through holes 112 and one or more through holes 113 which are formed in the insulator 111 and whose diameter is larger than the outer diameter of the pigtail 23 and which is disposed equidistant from the through holes 112 are provided. Thus, the cable connector 1 according to the first embodiment can improve the ground balance of the shielded twisted pair cable 2.

The connector mechanism 13 has been changed.

When the metal housing 131 is composed of two members, the upper cover 1311 and the lower cover 1312 are fixed by screws or the like to constitute the metal housing 131. In FIG. 9, the fixed portion of the metal housing 131 by a screw or the like is not shown.
