DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment. In addition, the components in the following embodiments include those that are replaceable and easy for a person skilled in the art, or those that are substantially the same.
[0010] [First embodiment] The connector CN to which the terminal module 1 is applied is used in a connection mechanism that electrically connects a wire harness used in a vehicle such as an automobile to a connection target of the wire harness. The wire harness is an assembly component in which a plurality of electric wires are bundled together to connect various devices mounted on the vehicle.
[0011] The connector CN includes a terminal module 1 for high-speed communication and an outer housing (not shown) that houses and holds the terminal module 1. As shown in Fig. 2 and Fig. 4, the terminal module 1 includes a wiring material 100 formed of a braided shielded wire, an inner terminal 200 connected to an end of the wiring material 100, an inner sleeve 300 assembled to the wiring material 100, an inner housing 400 that houses the inner terminal 200, and an outer terminal 500 assembled to the outside of the inner housing 400 and the inner sleeve 300. The inner sleeve 300 is provided with a protruding portion 320 that protrudes toward the outside (the outer terminal 500 side). The terminal module 1 of this embodiment realizes a configuration that can improve the fastening force of the braided body 130 of the wiring material 100 to the outer terminal 500 by sandwiching the braided body 130 of the wiring material 100 folded back to the outside of the inner sleeve 300 between the protruding portion 320 of the inner sleeve 300 and the outer terminal 500. Hereinafter, each component of the terminal module 1 will be described in detail with reference to Figs. 1 to 4.
[0012] In the following description, of the first, second, and third directions that intersect with each other, the first direction is referred to as the "length direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". The length direction X, width direction Y, and height direction Z are perpendicular to each other. The length direction X typically corresponds to the axial direction of the wiring material 100, the extension direction of the inner terminal 200, etc. The width direction Y corresponds to the direction in which the pair of inner terminals 200 are arranged, etc. Unless otherwise specified, each direction used in the following description will be described as a direction in a state in which each part of the terminal module 1 is assembled.
[0013] Moreover, the tip side (front side) in the length direction X typically corresponds to the mating connector side when the connector CN is mated with the mating connector, and corresponds to the inner terminal 200 side when each part of the terminal module 1 is assembled. Moreover, the base side (rear side) in the length direction X typically corresponds to the connector CN side when the connector CN is mated with the mating connector, and corresponds to the wiring material 100 side when each part of the terminal module 1 is assembled.
[0014] [Routing material] The wiring material 100 is a cable for differential transmission, for example, an Ethernet (registered trademark) cable. The wiring material 100 is a TP electric wire (TP: Twisted Pair), which is a pair of electric wires 110 (described later) bundled together. The wiring material W is a communication cable that transmits electric signals and the like using a pair of electric wires 110, and is shielded by a metal foil 120 and a braid 130 to block noise.
[0015] As shown in Figs. 2 and 4, the wiring material 100 of this embodiment includes a pair of electric wires 110, a metal foil 120 covering the pair of electric wires 110, a braided body 130, and a covering portion 140.
[0016] The electric wire 110 is an insulated electric wire composed of a linear conductor portion 111 having electrical conductivity and an insulating coating portion 112 having insulating properties that covers the outside of the conductor portion 111. In the electric wire 110, the cross-sectional shape of the conductor portion 111 (cross-sectional shape in a direction intersecting the extending direction) is approximately circular, and the cross-sectional shape of the insulating coating portion 112 is approximately annular, so that the cross-sectional shape of the electric wire 110 as a whole is approximately circular. Therefore, the conductor portion 111 of the electric wire 110 is covered by the insulating coating portion 112.
[0017] 2 and 4, the electric wire 110 of this embodiment has an end 110L located on the tip side in the length direction X protruding from the end of the covering portion 140. Of the end 110L protruding from the covering portion 140, the root portion (also called the base end portion) 110La of the electric wire 110 has the conductor portion 111 covered with the insulating covering portion 112. Of the end 110L, the end of the wiring material 100, i.e., the tip portion 110Lb corresponding to the end of the electric wire 110, has the insulating covering portion 112 stripped off to expose the conductor portion 111, and the inner terminal 200 is provided on the conductor portion 111. In this embodiment, the root portion 110La of the electric wire 110 corresponds to the root portion of the conductor portion 111, and the tip portion 110Lb of the electric wire 110 corresponds to the tip portion of the conductor portion 111.
[0018] The metal foil 120 is a paper-like metal piece made of a conductive metal material such as copper or aluminum. In the metal foil 120 of this embodiment, an end 120L located on the tip side in the length direction X is exposed from the covering portion 140. In addition, the end 120L exposed from the covering portion 140 covers the root portion 110La of the electric wire 110, and is disposed between the insulating covering portion 112 of the root portion 110La and the root portion 130La of the braided body 130 described later.
[0019] The braided body 130 is formed by weaving a braided wire made of a metal material such as copper or aluminum having electrical conductivity. The braided body 130 of this embodiment is formed in a substantially cylindrical shape along the length direction X, and as shown in FIG. 4, an end portion 130L located at the tip side in the length direction X is exposed from the covering portion 140. In addition, of the end portion 130L exposed from the covering portion 140, a root portion (also called a proximal portion) 130La covers the root portion 110La of the electric wire 110, and is disposed between an end portion 120L of the metal foil 120 covering the root portion 110La and an inner sleeve 300 described later. In addition, of the end portion 130L, a tip portion 130Lb corresponding to the terminal of the braided body 130 is folded back to the outside and disposed on the outer surface 310mb side of the inner sleeve 300.
[0020] The covering portion 140 is a sheath formed of an insulating resin material such as polyvinyl chloride or polyethylene. The covering portion 140 of this embodiment is formed in a substantially cylindrical shape along the length direction X, and is disposed on the outside of the braided body 130 described above, thereby becoming the outermost layer of the wiring material 100. Therefore, the covering portion 140 can cover the pair of electric wires 110, the metal foil 120, and the braided body 130 collectively.
[0021] [Inner terminal] The inner terminal 200 is made of a conductive metal material such as copper or aluminum, and is electrically connected to a terminal on the mating connector side when the connector CN is fitted to the mating connector. The inner terminal 200 is formed by forming a single sheet metal into a shape corresponding to each part by various processes such as press working including punching and bending, so that each part is integrally formed three-dimensionally.
[0022] The inner terminal 200 of this embodiment includes an electrical connection portion 210 and a crimping portion 220, as shown in FIGS.
[0023] The electrical connection portion 210 is located at the tip end side in the length direction X, and is a portion that is connected to a mating inner terminal when the connector CN is fitted to a mating connector. The shape of the electrical connection portion 210 is not particularly limited, and the connection type with the terminal on the mating connector side is also not particularly limited.
[0024] The crimping portion 220 is located on the base end side in the length direction X, and is a portion to which an end of the electric wire 110 is connected. The crimping portion 220 of this embodiment crimps the tip portion 110Lb of the electric wire 110, thereby crimping the inner terminal 200 to the conductor portion 111 of the electric wire 110. Therefore, the inner terminal 200 of this embodiment is assembled to the tip portion 110Lb of the electric wire 110 via the crimping portion 220, and is physically and electrically connected to the conductor portion 111 of the electric wire 110. The shape of the crimping portion 220 is not particularly limited, and the connection type with the electric wire 110 is not limited to crimping.
[0025] [Inner Sleeve] The inner sleeve 300 is a crimped sleeve made of conductive metal material such as copper, aluminum, etc. The inner sleeve 300 is formed by forming a single sheet metal into shapes corresponding to each part by various processes such as press working including punching and bending, so that each part is integrally formed three-dimensionally.
[0026] The inner sleeve 300 of this embodiment includes a main body portion 310 and a protruding portion 320, as shown in FIGS.
[0027] The main body 310 is a portion formed in a substantially cylindrical shape along the longitudinal direction X. The main body 310 of this embodiment is configured to include a pair of insertion openings 310k that open in the longitudinal direction X.
[0028] The insertion opening 310k is a portion defined and formed by an end of the main body portion 310. Note that the end of the main body portion 310 referred to here is the edge portion 310e of the main body portion 310.
[0029] 4, the main body 310 of this embodiment is attached to the root portion 110La of the electric wire 110 extending from the end of the covering portion 140. The main body 310 is crimped to the wiring material 100 by crimping together the electric wire 110 inserted inside, the metal foil 120 covering the root portion 110La of the electric wire 110, and the braided body 130. Therefore, the inner sleeve 300 of this embodiment is physically and electrically connected to the metal foil 120 covering the outer surface of the wiring material 100 and the braided body 130 via the main body 310.
[0030] As shown in Fig. 3, the protruding portion 320 is a stepped portion formed on the outside of the main body portion 310. The inner sleeve 300 of this embodiment is formed from a single piece of sheet metal as described above. Therefore, the protruding portion 320 of this embodiment is formed by bending the first protruding piece 311 formed on the end of the substantially cylindrical main body portion 310 by punching or the like, outward from the main body portion 310. Moreover, the protruding portion 320 is folded back along the outer surface 310mb of the main body portion 310 by bending the first protruding piece 311 from the root portion 311a and tilting it toward the outer surface 310mb of the main body portion 310.
[0031] 3, the protrusions 320 are formed in a substantially rectangular shape and are provided at the rear end 310a of the main body 310 located on the base end side in the longitudinal direction X. Four protrusions 320 are provided and arranged at equal intervals along the circumferential direction of the inner sleeve 300. Therefore, an edge 310ea on the rear end 310a side of the main body 310 forming the insertion opening 310k on the base end side in the longitudinal direction X is formed by the root portions 311a of the first protruding pieces 311. The protrusions 320 are preferably provided at equal intervals, but their positions are not particularly limited, and the intervals between the protrusions 320 are not particularly limited.
[0032] 4, the protrusion 320 is bent so as to be in close contact with the outer surface 310mb of the main body 310 and overlap with no gaps. Therefore, an edge 310ea on the rear end 310a side of the main body 310 in this embodiment is formed by a curved surface (R-shape).
[0033] [Inner housing] The inner housing 400 is formed of an insulating resin material, and accommodates and holds the inner terminal 200 assembled to the wiring material 100. The inner housing 400 of this embodiment includes a terminal accommodating portion 410, as shown in Figs. 1, 2, and 4.
[0034] The terminal accommodating portion 410 is formed in a substantially cylindrical shape along the length direction X, and is a portion that accommodates therein the electrical connection portion 210 of the inner terminal 200. In this embodiment, two terminal accommodating portions 410 are provided, and the terminal accommodating portions 410 are arranged at intervals in the width direction Y (see FIGS. 1 and 2).
[0035] [Outer terminal] The outer terminal 500 is made of a conductive metal material such as copper or aluminum, and is electrically connected to a terminal on the mating connector side when the connector CN is mated with the mating connector. Similarly to the inner terminal 200, the outer terminal 500 is made of a single sheet metal that is shaped by various processes such as press working including punching and bending to fit the shapes of each part, so that each part is integrally formed three-dimensionally.
[0036] 1, 2, and 4, the outer terminal 500 of this embodiment includes a main body 510. The main body 510 includes an attachment opening 510k that opens in the longitudinal direction X, an accommodating space 510s as an internal space, an electrical connection portion 511, and a crimping portion 512.
[0037] The main body 510 is formed in a substantially cylindrical shape along the length direction X, and receives and holds the inner terminal 200, the inner sleeve 300, and the inner housing 400, which are assembled to the wiring material 100.
[0038] The mounting opening 510k is provided at the rear end of the main body 510 located on the base end side in the longitudinal direction X, and is a portion defined and formed by the end of the main body 510. Note that the end of the main body 510 here refers to the edge of the main body 510 on the rear end side.
[0039] The accommodating space 510s is a portion defined and formed by the wall of the main body 510. In the outer terminal 500 of this embodiment, the inner terminal 200 assembled to the inner housing 400 can be accommodated in the accommodating space 510s by inserting the inner housing 400 through the mounting opening 510k. At the same time, by accommodating the inner terminal 200 in the accommodating space 510s, the end 110L of the electric wire 110 connected to the inner terminal 200 and the inner sleeve 300 assembled to the end 110L can be accommodated in the accommodating space 510s.
[0040] The electrical connection portion 511 is located at the tip end side in the length direction X, and is a portion that is connected to a terminal on the mating connector side when the connector CN is fitted to the mating connector. Note that the shape of the electrical connection portion 511 is not particularly limited, and the connection format with the terminal on the mating connector side is also not particularly limited.
[0041] The crimping portion 512 is located on the base end side in the length direction X, and is a portion to which the root portion 110La of the electric wire 110 protruding from the end of the covering portion 140 is connected. The crimping portion 512 of this embodiment crimps the inner sleeve 300 attached to the root portion 110La of the electric wire 110 together with the end of the covering portion 140, thereby crimping the outer terminal 500 to the wiring material 100. Therefore, the outer terminal 500 of this embodiment is attached to the root portion 110La of the electric wire 110 and is physically and electrically connected to the braid 130 covering the outer surface of the inner sleeve 300 via the crimping portion 512.
[0042] As shown in FIG. 4, when the inner sleeve 300 and the end of the covering portion 140 are crimped together, the crimped portion 512 has an inclined portion 512t formed by the protruding portion 320 provided on the inner sleeve 300. As shown in FIG.
[0043] The inclined portion 512t is a recess formed by crimping the inner sleeve 300 made of a metal material that is difficult to deform and the covering portion 140 made of a resin material that is easily deformed. As shown in Fig. 4, the inner sleeve 300 of this embodiment is higher (thicker) on the rear end 310a side due to the protruding portion 320. Therefore, the inclined portion 512t of this embodiment is inclined in a direction in which the outer shape of the outer terminal 500 decreases in diameter toward the base end side in the length direction X in accordance with the stepped shape formed by the protruding portion 320.
[0044] Next, the assembly operation of the terminal module 1 will be described.
[0045] First, a worker assembles the inner terminal 200 to an end of the wiring material 100. At this time, the end portions on the tip side of the pair of electric wires 110, the metal foil 120, and the braided body 130 constituting the wiring material 100 each protrude from the end of the covering portion 140. Also, the insulating covering portion 112 is stripped from the end of each electric wire 110, so that the conductor portion 111 is exposed from the end of the insulating covering portion 112. Then, the inner terminal 200 is electrically connected to the conductor portion 111 of the electric wire 110 by crimping the end of the electric wire 110 with the crimping portion 220.
[0046] Then, the worker assembles the inner sleeve 300 to the end of the wiring material 100. At this time, the inner sleeve 300 is attached from the tip side (electrical connection part 210 side) of the inner terminal 200. More specifically, as shown in FIG. 4, the inner sleeve 300 is assembled to the root part 110La of the electric wire 110 protruding from the covering part 140, that is, the part where the conductor part 111 is covered by the insulating covering part 112. Therefore, the conductor part 111 and the insulating covering part 112 of the electric wire 110, the end part 120L of the metal foil 120 located outside the electric wire 110, and the root part 130La of the braided body 130 located outside the metal foil 120 are arranged on the inner side of the inner sleeve 300. In addition, the multiple protrusions 320 provided on the rear end part 310a of the inner sleeve 300 are arranged in a state of being adjacent to the end of the covering part 140.
[0047] The inner sleeve 300 is electrically connected to the end 120L of the metal foil 120 located outside the insulating coating portion 112 of the electric wire 110 and the root portion 130La of the braided body 130 by crimping the electric wire 110, the metal foil 120 covering the electric wire 110, and the root portion 130La of the braided body 130 together. The end 120L of the metal foil 120 and the root portion 130La of the braided body 130 are sandwiched between the electric wire 110 and the main body portion 310 of the inner sleeve 300, so that their positions relative to the root portion 110La of the electric wire 110 are fixed.
[0048] Then, the worker assembles the inner terminals 200 into the inner housing 400. At this time, the inner terminals 200 are inserted into the terminal accommodating portions 410 of the inner housing 400, respectively.
[0049] Then, the worker assembles the outer terminal 500. At this time, the outer terminal 500 is attached to the inner housing 400 from the tip side. When the inner housing 400 is accommodated inside the outer terminal 500 (accommodation space 510s), the inner terminal 200 assembled to the inner housing 400 is also accommodated, and the end 110L of the electric wire 110 connected to the inner terminal 200 and the inner sleeve 300 assembled to the end 110L are also accommodated. Therefore, as shown in FIG. 4, the inner housing 400 is disposed on the tip side (electrical connection portion 511 side) in the length direction X of the outer terminal 500, and the inner sleeve 300 is disposed on the base end side (crimping portion 512 side) in the length direction X of the outer terminal 500.
[0050] The outer terminal 500 is electrically connected to the end 120L of the metal foil 120 located inside the inner sleeve 300 and the root portion 130La of the braided body 130 by crimping the inner sleeve 300 assembled to the end 110L of the electric wire 110 and the terminal of the covering portion 140 together with the crimping portion 512. The outer terminal 500 is also electrically connected to the tip portion 130Lb of the braided body 130 folded back to the outside of the inner sleeve 300. Therefore, the metal foil 120 and the braided body 130 are electrically connected to the outer terminal 500 assembled to the outside of the inner sleeve 300 while covering the pair of electric wires 110 together, thereby appropriately shielding noise.
[0051] The position of the tip portion 130Lb of the braided body 130 relative to the inner sleeve 300 is fixed by being sandwiched between the protruding portion 320 of the inner sleeve 300 and the crimping portion 512 of the outer terminal 500. When the tip portion 130Lb of the braided body 130 is pulled in the direction in which the wiring material 100 is pulled out, the tip portion 130Lb is caught by the protruding portion 320 of the inner sleeve 300, thereby preventing the tip portion 130Lb from shifting in position relative to the inner sleeve 300.
[0052] More specifically, the outer terminal 500 has an inclined portion 512t formed in the crimping portion 512, so that when the wiring material 100 is pulled in the direction of being pulled out, the edge portion 310ea (the root portion of the protrusion portion 320 formed in the rear end portion 310a of the main body portion 310) of the inner sleeve 300 comes into contact with the inner sleeve 300. Therefore, when the wiring material 100 is pulled in the direction of being pulled out, the tip portion 130Lb of the braided body 130 is sandwiched between the edge portion 310ea of the rear end portion 310a of the inner sleeve 300 and the inclined portion 512t of the outer terminal 500. The tip portion 130Lb of the braided body 130 is sandwiched with a stronger force by the external force applied when the wiring material 100 is pulled. Therefore, the tip portion 130Lb of the braided body 130 can be more reliably suppressed from being displaced relative to the inner sleeve 300.
[0053] In addition, since the root portion of the protrusion 320 of the inner sleeve 300 is formed in an R-shape, it is possible to suppress damage to the tip portion 130Lb of the braided body 130 by the edge portion 310ea on the rear end portion 310a side when the edge portion 310ea contacts the inclined portion 512t of the outer terminal 500. Therefore, the tip portion 130Lb of the braided body 130 is more appropriately fixed to the inner sleeve 300, and is electrically connected to the outer terminal 500 assembled to the outside of the inner sleeve 300, thereby more appropriately shielding noise.
[0054] The terminal module 1 described above includes a wiring material 100 including a conductive conductor portion 111, a braided body 130 covering the conductor portion 111, and a covering portion 140 that is insulating and is positioned outside the braided body 130 to cover the conductor portion 111; an inner terminal 200 that is attached to the tip portion of the conductor portion 111 protruding from the end of the covering portion 140 (the tip portion 110Lb of the electric wire 110) and is electrically connected to the conductor portion 111; The cable includes an inner sleeve 300 assembled to a root portion (root portion 110La of electric wire 110) of conductor portion 111 extending from the terminal and having an outer surface covered by a braided body 130 folded back outward, an inner housing 400 for accommodating an inner terminal 200, and an outer terminal 500 assembled to the outside of the inner housing 400 and the inner sleeve 300 and electrically connected to the braided body 130 folded back outward of the inner sleeve 300. The inner sleeve 300 has a main body portion 310 formed in a cylindrical shape and a protruding portion 320 formed on the outside of the main body portion 310, and the outer terminal 500 has a crimping portion 512 that is crimped to be electrically connected to the wiring material 100, and the braided body 130 of the wiring material 100 is sandwiched between the protruding portion 320 of the inner sleeve 300 and the crimping portion 512 of the outer terminal 500.
[0055] According to such a configuration, the inner sleeve 300 has a step formed on the outside of the main body 310 by the protruding portion 320. Therefore, the inner sleeve 300 can easily sandwich the braided body 130 between the outer terminal 500 and the protruding portion 320. When the braided body 130 is sandwiched between the protruding portion 320 of the inner sleeve 300 and the crimping portion 512 of the outer terminal 500, the braided body 130 is easily caught by the protruding portion 320 when the wiring material 100 is pulled in the direction of being pulled out. Therefore, the inner sleeve 300 can prevent the position of the braided body 130 from shifting by the protruding portion 320, and the terminal module 1 can improve the fixing force of the braided body 130 to the outer terminal 500.
[0056] Furthermore, the terminal module 1 can reduce the force required for crimping the crimping portion 512 of the outer terminal 500 by improving the fastening force of the braid 130 of the wiring material 100 to the outer terminal 500 by the protrusion 320 of the inner sleeve 300. Therefore, the terminal module 1 can crimp the outer terminal 500 to the wiring material 100 without significantly deforming the wiring material 100 housed inside the outer terminal 500. Therefore, the terminal module 1 can prevent the transmission characteristics of the wiring material 100 from deteriorating due to excessive deformation during crimping.
[0057] Furthermore, the protruding portion 320 of the inner sleeve 300 constituting the terminal module 1 described above is formed by folding back the first protruding piece 311 formed on the main body 310 along the outer surface 310mb of the main body 310. With this configuration, the protruding portion 320 can be provided on the outside of the inner sleeve 300 by a simpler method. In addition, the inner sleeve 300 can increase the strength of the part by folding back the first protruding piece 311 toward the outside, and can make the main body 310 and the protruding portion 320 less likely to deform. Therefore, the inner sleeve 300 can sufficiently secure the amount of step formed on the main body 310 by the protruding portion 320, and thus the braided body 130 is easily caught by the protruding portion 320 when the wiring material 100 is pulled in the direction in which the wiring material 100 is pulled out. Therefore, the terminal module 1 can more reliably improve the fixing force of the braided body 130 of the wiring material 100 to the outer terminal 500.
[0058] Furthermore, the outer terminal 500 constituting the terminal module 1 described above further has an inclined portion 512t provided in the crimping portion 512 and inclined in the direction in which the outer shape of the outer terminal 500 is reduced in diameter, and the protruding portion 320 of the inner sleeve 300 is provided at the rear end portion 310a of the main body portion 310 located on the side of the covering portion 140 of the wiring material 100. Also, the braided body 130 of the wiring material 100 is sandwiched between the protruding portion 320 of the inner sleeve 300 and the inclined portion 512t of the outer terminal 500. According to this configuration, the braided body 130 is sandwiched between the convex portion of the inner sleeve 300 formed by the protruding portion 320 and the concave portion of the crimping portion 512 of the outer terminal 500 formed by the inclined portion 512t. Furthermore, when the braided body 130 is pulled in the direction in which the wiring material 100 is pulled out, the root portion of the protrusion 320 formed at the rear end portion 310a of the inner sleeve 300 comes into contact with the inclined portion 512t formed at the crimping portion 512 of the outer terminal 500, and the braided body 130 is pinched with a stronger force. Therefore, when the braided body 130 is pulled in the direction in which the wiring material 100 is pulled out, the braided body 130 is more likely to be caught by the protrusion 320. Therefore, the terminal module 1 can more reliably improve the fixing force of the braided body 130 of the wiring material 100 to the outer terminal 500.
[0059] Furthermore, the protruding portions 320 of the inner sleeve 300 constituting the terminal module 1 described above are provided at intervals along the circumferential direction of the inner sleeve 300. According to such a configuration, the inner sleeve 300 can more reliably fix the braided body 130 by increasing the number of places where the braided body 130 is sandwiched between the outer terminal 500 and the protruding portions 320. Then, when the braided body 130 is pulled in the direction in which the wiring material 100 is pulled out, the braided body 130 is more likely to be caught by the protruding portions 320 when the braided body 130 is pulled out. Therefore, the inner sleeve 300 can prevent the position of the braided body 130 from being displaced by the protruding portions 320, and the terminal module 1 can improve the fixing force of the braided body 130 to the outer terminal 500.
[0060] [Second embodiment] Next, a connector CNA according to a second embodiment shown in Figures 5 and 6 and a terminal module 1A applied to the connector CNA will be described. The connector CNA differs from the connector CN according to the first embodiment in that the inner sleeve 300 is further provided with a retraction portion 330 that protrudes inward (toward the conductor portion 111). In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0061] The connector CNA includes a terminal module 1A for high-speed communication and an outer housing (not shown) that accommodates and holds the terminal module 1A. The terminal module 1A also includes a wiring material 100, an inner terminal 200, an inner sleeve 300A, an inner housing 400, and an outer terminal 500.
[0062] As shown in FIGS. 5 and 6, the inner sleeve 300A includes a main body portion 310, a protruding portion 320, and a retractable portion 330. As shown in FIG.
[0063] The retraction portion 330 is a portion where the outer shape of the main body portion 310 has a reduced diameter. The inner sleeve 300A of this embodiment is formed of a single sheet metal, similar to the inner sleeve 300. Therefore, the retraction portion 330 of this embodiment is formed by bending the second protruding piece 312 formed at the end of the substantially cylindrical main body portion 310 by punching or the like, toward the inside of the main body portion 310. In addition, the retraction portion 330 is tilted toward the inner surface 310ma of the main body portion 310 by bending the second protruding piece 312 from the root portion 312a.
[0064] 5, the retracted portions 330 are formed in a substantially rectangular shape and are provided at the front end 310b of the main body 310 located at the tip side in the longitudinal direction X. Four retracted portions 330 are provided and arranged at equal intervals along the circumferential direction of the inner sleeve 300. Therefore, the edge portion 310eb of the front end 310b of the main body 310 forming the insertion opening 310k at the tip side in the longitudinal direction X is formed by the tip portion 312b of each of the second protruding pieces 312. The retracted portions 330 are preferably provided at equal intervals, but their positions are not particularly limited, and the intervals between the retracted portions 330 are not particularly limited.
[0065] Next, an assembly operation of the terminal module 1A will be described. Note that in the following description, detailed description of the same operations as those in the first embodiment will be omitted.
[0066] First, a worker assembles the inner terminal 200 to the end of the wiring material 100, and then assembles the inner sleeve 300A to the end of the wiring material 100. At this time, the inner sleeve 300 is attached from the tip side (electrical connection part 210 side) of the inner terminal 200. Then, a plurality of retracting parts 330 provided on the front end part 310b of the inner sleeve 300 are arranged on the opposite side of the protruding part 320.
[0067] The inner sleeve 300A is electrically connected to the end 120L of the metal foil 120 located outside the insulating coating portion 112 of the electric wire 110 and the root portion 130La of the braided body 130 by crimping the electric wire 110, the metal foil 120 covering the electric wire 110, and the root portion 130La of the braided body 130 together. The end 120L of the metal foil 120 and the root portion 130La of the braided body 130 are sandwiched between the electric wire 110 and the main body portion 310 of the inner sleeve 300A, so that their positions relative to the root portion 110La of the electric wire 110 are fixed. In addition, the intermediate portion located between the root portion 130La and the tip portion 130Lb of the braided body 130 is brought closer to the conductor portion 111 side by the retraction portion 330 being deformed and bent inward when the inner sleeve 300A is crimped.
[0068] According to such a configuration of the inner sleeve 300A, as in the inner sleeve 300, a step is formed on the outside of the main body 310 by the protruding portion 320, so that the braided body 130 can be easily sandwiched between the outer terminal 500 and the protruding portion 320. When the braided body 130 is sandwiched between the protruding portion 320 of the inner sleeve 300A and the crimping portion 512 of the outer terminal 500, the braided body 130 is easily caught by the protruding portion 320 when the wiring material 100 is pulled in the direction of being pulled out. Therefore, the inner sleeve 300A can make the position of the braided body 130 less likely to shift by the protruding portion 320, and thus the terminal module 1A can improve the fixing force of the braided body 130 to the outer terminal 500. In addition, the braided body 130 can be brought closer to the conductor portion 111 side by the lead-in portion 330, so that the noise can be more appropriately shielded. Therefore, the terminal module 1A can improve the transmission characteristics of the wiring material 100.
[0069] The terminal modules 1, 1A according to the above-described embodiments of the present invention are not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.
[0070] For example, the method of forming the protruding portion 320 is not particularly limited as long as it can form a convex portion such as a step on the inner sleeve 300. Also, the method of forming the retracting portion 330 is not particularly limited as long as it can form a concave portion on the outside of the main body portion 310 of the inner sleeve 300.
[0071] Also, it has been explained that protruding portion 320 can be formed by bending plate-like first protruding piece 311 formed at the end of main body portion 310 outward, but there is no particular limitation on the bending angle of first protruding piece 311. Also, it has been explained that retracting portion 330 can be formed by bending plate-like second protruding piece 312 formed at the end of main body portion 310 inward, but there is no particular limitation on the bending angle of second protruding piece 312.
[0072] Furthermore, the number of the protruding portions 320 and the number of the retracting portions 330 are not particularly limited.
[0073] In addition, although it has been described that the protruding portion 320 is provided at the rear end portion 310a of the main body portion 310 and the retracting portion 330 is provided at the front end portion 310b of the main body portion 310, the positions at which the protruding portion 320 and the retracting portion 330 are provided are not particularly limited.
[0074] The inclination direction of the inclined portion 512t provided in the crimping portion 512 of the outer terminal 500 is not limited to the direction shown in Fig. 4. The inclined portion 512t may be provided at a position where the protruding portion 320 of the inner sleeve 300, 300A arranged on the inside can abut against the inclined portion 512t, and the position is not particularly limited.
[0075] Furthermore, the terminal module according to this embodiment may be configured by appropriately combining the components of the embodiment and modified examples described above. [Explanation of symbols]
