Description

Technical Field

[0001] The present invention relates to a connector and a method for manufacturing a connector. Background Art

[0002] Publication No. JP 2013-229334 A and WO 2018 / 230251 A1 describe a conventional first connector. The first connector includes an outer conductor, a center conductor and a body. The outer conductor includes a shell in a round tube shape and a pair of first connecting parts. The first connecting part is a part extending from the rear end of the shell, which is arranged behind the shell and spaced apart from each other in a direction orthogonal to the axial direction of the shell. The center conductor includes a terminal part and a second connecting part. The terminal part has a generally round tube shape and includes a distal part and a rear part. The distal part of the terminal part is concentric with the shell. The rear part of the terminal part is arranged between the rear of the shell and the first connecting part. The second connecting part is a plate extending substantially at right angles to the rear part of the terminal part, which is arranged between the rear of the shell and the first connecting part. The body is made of insulating material. The rear part of the shell, the part of the first connecting part, the rear part of the terminal part and the part of the second connecting part are insert molded inside the body. That is, the body covers the rear part of the shell, the part of the first connecting part, the rear part of the terminal part and the part of the second connecting part.

[0003] Another conventional connector or second connector is described in patent publication number JP 2015-162375 A. The second connector includes an outer conductor, a center conductor and a body. The outer conductor includes a shell in the shape of a circular tube and a first connecting portion. The first connecting portion is a plate extending from the rear end of the shell, which is arranged behind the shell. The center conductor includes a terminal portion and a second connecting portion. The terminal portion is concentric with the shell. The second connecting portion extends backward from the rear end of the terminal portion and is arranged behind the shell. The body is made of insulating material, is insert molded in the shell, and holds the terminal portion inside the shell. Summary of the invention

[0004] Technical issues

[0005] In the first connector, the distal portion of the terminal portion is arranged inside the housing, but the rear portion of the terminal portion and the second connection portion are arranged outside the housing. Similarly, in the second connector, the second connection portion of the center conductor is arranged outside the housing. Therefore, the first connector and the second connector have low electromagnetic interference (EMI) characteristics.

[0006] The present invention provides a connector having improved EMI characteristics and being easy to manufacture. The present invention provides a method for manufacturing the connector.

[0007] Technical Solution

[0008] A connector according to aspects of the present invention comprises a shell having conductivity, a body, a terminal and a cable. The shell comprises a shell body having a substantially tubular shape and extending along the first direction. The body is formed of an insulating resin insert-molded inside the shell body. The body is completely contained inside the shell body and is exposed to one side in the first direction from inside the shell body. The body comprises a receiving hole extending through the body along the first direction. The terminal is completely disposed inside the shell body. The terminal comprises a distal portion, a middle portion and a rear portion. The middle portion of the terminal is at least partially retained in the receiving hole of the body. The distal portion of the terminal protrudes from the receiving hole of the body to one side in the first direction and is disposed inside the shell body. Alternatively, the distal portion of the terminal is disposed in the receiving hole of the body and is exposed to one side in the first direction from the receiving hole. The rear portion of the terminal is disposed in the receiving hole of the body, or alternatively protrudes from the receiving hole of the body to the other side in the first direction. The cable is partially received inside the housing body from the other side in the first direction, and is connected to the rear portion of the terminal inside the housing body. The first direction is an axial direction of the housing body.

[0009] A method for manufacturing a connector according to an aspect of the present invention comprises the following steps: (1) closing a first mold including a first insert and a second mold including a second insert together and accommodating a shell into the cavities of the first mold and the second mold, the shell including a shell body having a substantially tubular shape and extending in a first direction, blocking the shell body of the shell from one side in the first direction with the first insert, and inserting the second insert into the shell body from the other side in the first direction so that the second insert abuts against the first insert and the shell body is blocked from the other side in the first direction with the second insert, so that the shell body, the first insert and the second insert define an injection space and a door G in the first insert is connected to the injection space; (2) 2) injecting molten resin into the injection space in the shell body through the door, filling the molten resin into the injection space, and solidifying the filled molten resin to completely insert the body into the shell body; (3) opening the first mold and the second mold separately from each other, removing the first insert and the second insert from the shell and the body, thereby forming a receiving hole in the portion of the body from which the second insert has been removed; (4) preparing terminals and cables connected to the terminals; and (5) inserting the terminals into the shell body from the other side in the first direction to hold the terminals in the receiving hole of the body so that the terminals are completely arranged inside the shell body, and partially inserting the cables into the shell body from the other side in the first direction.

[0010] Advantageous Effects of the Invention

[0011] The connector and the method for manufacturing the connector according to the above aspects provide improved EMI characteristics of the connector for the following reasons. The body is insert molded and is completely accommodated inside the housing body; the middle portion of the terminal is at least partially retained in the accommodation hole of the body; the terminal is completely disposed inside the housing body; and the cable is connected to the rear portion of the terminal inside the housing body. Therefore, the entire terminal and the portion where the terminal and the cable are connected together are disposed inside the housing body and shielded by the housing body, thereby improving the EMI characteristics of the connector.

[0012] In addition, the connector is easy to manufacture for the following reasons. Since the body is insert-molded in the housing body, the step of assembling the body into the housing body can be advantageously omitted. The body is provided with the receiving hole, and the middle portion of the terminal is at least partially held by the body only by inserting the terminal into the receiving hole. Therefore, it is easy to assemble the terminal into the body. BRIEF DESCRIPTION OF THE DRAWINGS

Figures 1A to 3B A connector C1 according to a first embodiment is shown. Figures 1A to 3B The Y-Y' direction (first direction) is shown. The Y-Y' direction includes the Y direction (one side in the first direction) and the Y' direction (the other side in the first direction). Figure 1A to Figure 1B and Figures 2B to 3B The XX' direction (second direction) is shown. The XX' direction is substantially orthogonal to the YY' direction, and includes the X direction (one side in the second direction) and the X' direction (the other side in the second direction). Figures 1A to 2A and FIG. 3A to FIG. 3B The Z-Z' direction (third direction) is shown. The Z-Z' direction is substantially orthogonal to the Y-Y' direction and the XX' direction, and includes the Z direction (one side in the third direction) and the Z' direction (the other side in the third direction).

[0030] The connector C1 is a coaxial connector and includes a housing 100 having conductivity.

[0031] The housing 100 may be made of a conductive material (e.g., a metal or a carbon material such as a carbon nanotube). Alternatively, the housing 100 may include a tubular body made of an insulating material and a metal film electroplated or vapor-deposited on the outer surface of the tubular body. The housing 100 may, but need not, be manufactured by subjecting a conductive rod to a machining process.

[0032] The housing 100 includes a housing body 110 having a generally tubular shape, such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross section along the Z-Z' direction and the X-X' direction), and extending in the Y-Y' direction. The housing body 110 may be provided with neither a notch, a joint between the two ends of the metal plate generated when the metal plate is formed into a tubular shape, nor a through hole. The housing 100 may be provided with neither a joint, a notch nor a through hole in its entirety. If a through hole is provided, the through hole extends through the housing body 110 or the housing 100 in a direction orthogonal to the Y-Y' direction. The housing body 110 includes a distal portion on the Y direction side, a rear portion 112 on the Y' direction side, a generally tubular inner peripheral surface 113 such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross section along the Z-Z' direction and the X-X' direction), and an outer peripheral surface. The distal portion of the housing body 110 includes a distal end 111, which is also the distal end of the housing 100 on the Y direction side. Note that the YY′ direction is the axial direction of the housing body 110.

[0033] The housing 100 may further include at least one annular groove 120 and / or at least one annular protrusion 130. For ease of description, hereinafter, the at least one annular groove 120 is described as a single annular groove 120, but in the case where a plurality of annular grooves are provided, each of the annular grooves is configured similarly to the single annular groove 120. In addition, hereinafter, the at least one annular protrusion 130 is described as a single protrusion 130, but in the case where a plurality of protrusions 130 are provided, each of the protrusions is configured similarly to the single annular protrusion 130.

[0034] The annular groove 120 is a recessed portion of a substantially annular shape (substantially circular or polygonal) provided in the inner circumferential surface 113 of the housing body 110. The annular groove 120 is provided so that the central axis of the annular groove 120 substantially coincides with the central axis of the housing body 110, and the annular groove 120 is recessed away from the central axis of the housing body 110 (see Figure 2A and Figure 2B ). The annular groove 120 is connected to the interior of the housing body 110. The annular groove 120 includes a bottom surface having a substantially annular shape (eg, a substantially circular or polygonal annular shape), a first wall surface having a substantially annular shape on the Y direction side, and a second wall surface having a substantially annular shape on the Y' direction side.

[0035] The annular protrusion 130 is a ridge of a substantially annular shape (substantially circular or polygonal annular shape) provided on the inner circumferential surface 113 of the housing body 110. The annular protrusion 130 is provided so that the central axis of the annular protrusion 130 substantially coincides with the central axis of the housing body 110, and the annular protrusion 130 protrudes toward the central axis of the housing body 110 (see Figure 2A and Figure 2B The annular protrusion 130 includes a top surface having a substantially annular shape (eg, a substantially circular or polygonal annular shape), a first wall surface having a substantially annular shape on the Y direction side, and a second wall surface having a substantially annular shape on the Y′ direction side.

[0036] The housing 100 may also include a bottom 140 , a hole 150 , and a cable holder 160 .

[0037] The bottom portion 140 is integrally provided with the rear portion 112 of the housing body 110, and forms a bottom portion on the Y′ direction side of the housing body 110 (see FIG. 1 ). FIG. 2A to FIG. 3B ). Therefore, the housing body 110 and the bottom 140 constitute a substantially bottom-closed tube. The bottom 140 includes a first surface 141 on the Y-direction side. The first surface 141 of the bottom 140 faces the interior of the housing body 110.

[0038] The cable holder 160 is generally shaped like a column (eg, a column with a generally circular or polygonal cross section), and extends from the bottom 140 along the Y′ direction (see FIG. 1 ). FIG. 2A to FIG. 3B ). The cable holder 160 may, but need not, have a cross-sectional outer dimension along the XX' direction and the ZZ' direction that is smaller than the outer dimension of the housing body 110. The cable holder 160 includes an outer peripheral surface of a generally tubular shape such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross-section along the ZZ' direction and the XX' direction) and a rear surface on the Y' direction side. The cable holder 160 may be omitted.

[0039] In the case where the cable holder 160 is provided, the hole 150 extends through the bottom 140 and the cable holder 160 in the YY′ direction (see Figure 2A and Figure 2B ). In the case where the cable holder 160 is not provided, the hole 150 extends through the bottom 140 in the Y-Y' direction. In either case, the hole 150 is a hole shaped roughly like a column (e.g., a column with a roughly circular or polygonal cross-section), extending in the Y-Y' direction, and the dimensions of the cross-section of the hole 150 along the X-X' direction and the Z-Z' direction are smaller than the inner dimensions of the cross-section of the housing body 110 along the X-X' direction and the Z-Z' direction.

[0040] In the case where the cable holder 160 is provided, the rear end of the cable holder 160 is the rear end of the housing 100. In the case where the cable holder 160 is not provided, the end of the bottom 140 on the Y' direction side is the rear end of the housing 100. The bottom 140, the hole 150, and the cable holder 160 may be omitted, in which case the rear end of the housing body 110 on the Y' direction side is the rear end of the housing 100.

[0041] The housing 100 may further include a generally annular engagement groove 170 (see FIG. 3A to FIG. 3B ). The engagement groove 170 is a recessed portion of a substantially annular shape (substantially circular or polygonal annular shape) provided in the outer peripheral surface of the housing body 110. The engagement groove 170 is provided so that the central axis of the engagement groove 170 substantially coincides with the central axis of the housing body 110, and the engagement groove 170 is recessed toward the central axis side of the housing body 110. The engagement groove 170 may be omitted.

[0042] The connector C1 further includes a body 200. The body 200 is composed of a molded insulating resin insert-molded inside the housing body 110 of the housing 100. The body 200 is completely accommodated in the housing body 110 and is exposed from the housing body 110 in the Y direction.

[0043] The body 200 includes a main body 210. The main body 210 includes a distal portion 211, a middle portion 212, and a rear portion 213 (see FIG. 2A to FIG. 2B ). The distal portion 211 of the body 210 is generally shaped like a column (e.g., a column with a generally circular or polygonal cross section), extends from the middle portion 212 along the Y direction, and is disposed inside the shell body 110. The middle portion 212 of the body 210 is a portion between the distal portion 211 and the rear portion 213, is generally shaped like a column (e.g., a column with a generally circular or polygonal cross section), and is disposed inside the shell body 110. The rear portion 213 of the body 210 is generally shaped like a column (e.g., a column with a generally circular or polygonal cross section), extends from the middle portion 212 along the Y' direction, and is disposed inside the shell body 110.

[0044] The body 200 may also include a tube 220 (see FIG. 2A to FIG. 3B ). The tube 220 extends from the middle portion 212 along the Y direction and surrounds the distal portion 211 of the body 210, wherein a substantially annular gap is provided between the tube 220 and the distal portion 211 of the body 210. Therefore, the inner dimensions of the cross-section of the tube 220 along the XX' direction and the ZZ' direction are larger than the outer dimensions of the cross-section of the distal portion 211 of the body 210 along the XX' direction and the ZZ' direction. The tube 220 may be omitted.

[0045] In the case where the tube 220 is provided, the outer circumferential surface of the middle portion 212 of the main body 210, the outer circumferential surface of the rear portion 213 of the main body 210, and the outer circumferential surface of the tube 220 together form the outer circumferential surface of the body 200, and can be in close contact with the inner circumferential surface 113 of the shell body 110. In this case, the outer dimensions of the cross-sections of the middle portion 212 of the main body 210, the rear portion 213 of the main body 210, and the tube 220 along the XX' direction and the ZZ' direction are all equal to the inner dimensions of the cross-sections of the shell body 110 along the XX' direction and the ZZ' direction.

[0046] In the case where the tube 220 is not provided, there may be a substantially annular gap between the distal portion 211 of the main body 210 and the shell body 110, or alternatively, the outer peripheral surface of the distal portion 211 of the main body 210 may be in close contact with the inner peripheral surface 113 of the shell body 110. In the former case, the outer dimensions of the cross section of the distal portion 211 of the main body 210 along the XX' direction and the ZZ' direction are smaller than the inner dimensions of the cross section of the shell body 110 along the XX' direction and the ZZ' direction, and the outer peripheral surface of the middle portion 212 of the main body 210 and the outer peripheral surface of the rear portion 213 together form the outer peripheral surface of the body 200 and are in close contact with the inner peripheral surface 113 of the shell body 110. In the latter case, the outer dimensions of the cross section of the distal portion 211 of the main body 210 along the X-X' direction and the Z-Z' direction are equal to the inner dimensions of the cross section of the shell body 110 along the X-X' direction and the Z-Z' direction, and the outer peripheral surface of the distal portion 211 of the main body 210, the outer peripheral surface of the middle portion 212 and the outer peripheral surface of the rear portion 213 together form the outer peripheral surface of the main body 200, and are in close contact with the inner peripheral surface 113 of the shell body 110.

[0047] The body 200 has a first outermost end 201 and a second outermost end 202. The first outermost end 201 is the outermost end of the body 200 on the Y direction side. For example, in the case where the tube 220 is provided, the first outermost end 201 may be the distal end of the tube 220 on the Y direction side (see Figure 2A and Figure 2B ), or alternatively, may be the distal end (not shown) of the distal portion 211 of the body 210 on the Y direction side. In the case where the tube 220 is not provided, the first outermost end 201 may be the distal end of the distal portion 211 of the body 210 on the Y direction side. The second outermost end 202 is the outermost end of the body 200 on the Y' direction side. For example, the second outermost end 202 may be the rear end of the rear portion 213 of the body 210 on the Y' direction side.

[0048] In the case where the bottom 140 of the housing 100 and the cable holder 160 are provided, or alternatively, in the case where the bottom 140 of the housing 100 is provided but the cable holder 160 thereof is not provided, the housing 100 and the body 200 may also have the following configuration (1) or (2):

[0049] (1) The size of the body 200 in the YY' direction is smaller than that of the housing body 110 (see Figures 1A to 3B The first outermost end 201 of the body 200 is located on the Y' direction side relative to the distal end 111 of the housing body 110, and the second outermost end 202 of the body 200 is in close contact with the first surface 141 of the bottom 140 from the Y direction side and is located on the Y direction side relative to the rear end of the housing 100.

[0050] (2) The size of the body 200 in the Y-Y' direction is substantially equal to the size of the housing body 110 (not shown). The first outermost end 201 of the body 200 is located at substantially the same position as the distal end 111 of the housing body 110 in the Y-Y' direction, and the second outermost end 202 of the body 200 is in close contact with the first surface 141 of the bottom 140 from the Y direction side and is located on the Y direction side relative to the rear end of the housing 100.

[0051] In the case where neither the bottom 140 of the housing 100 nor the cable holder 160 is provided, the housing 100 and the body 200 may also have one of the following configurations (3) to (6):

[0052] (3) The size of the body 200 in the Y-Y' direction is smaller than that of the housing body 110 (not shown). The first outermost end 201 of the body 200 is located on the Y' direction side relative to the distal end 111 of the housing body 110, and the second outermost end 202 of the body 200 is located on the Y' direction side relative to the rear end of the housing body 110.

[0053] (4) The size of the body 200 in the Y-Y' direction is smaller than that of the housing body 110 (not shown). The first outermost end 201 of the body 200 is located on the Y' direction side relative to the distal end 111 of the housing body 110, and the second outermost end 202 of the body 200 is located at substantially the same position as the rear end of the housing body 110 in the Y-Y' direction.

[0054] (5) The size of the body 200 in the Y-Y' direction is smaller than that of the housing body 110 (not shown). The first outermost end 201 of the body 200 is located at substantially the same position as the distal end 111 of the housing body 110 in the Y-Y' direction, and the second outermost end 202 of the body 200 is located on the Y direction side relative to the rear end of the housing body 110.

[0055] (6) The size of the body 200 in the Y-Y' direction is substantially equal to the size of the housing body 110 (not shown). The first outermost end 201 of the body 200 is located at substantially the same position as the distal end 111 of the housing body 110 in the Y-Y' direction, and the second outermost end 202 of the body 200 is located at substantially the same position as the rear end of the housing body 110 in the Y-Y' direction.

[0056] In the case where the housing 100 has at least one annular groove 120, the body 200 further includes at least one annular protrusion 230 (see Figures 2A to 3B ). Depending on the number of the at least one annular groove 120, the at least one annular protrusion 230 may be a single protrusion or a plurality of protrusions.

[0057] For ease of description, at least one annular protrusion 230 is described as a single annular protrusion 230 hereinafter, but in the case where a plurality of annular protrusions 230 are provided, each of the plurality of annular protrusions 230 is configured similarly to the single annular protrusion 230 .

[0058] The annular protrusion 230 is a ridge of a substantially annular shape (substantially circular or polygonal annular shape) provided on the outer peripheral surface of the body 200. The annular protrusion 230 is provided so that the central axis of the annular protrusion 230 substantially coincides with the central axis of the housing body 110 of the housing 100. The annular protrusion 230 protrudes away from the central axis of the housing body 110 of the housing 100. In other words, the annular protrusion 230 protrudes toward the annular groove 120 of the housing 100. The annular protrusion 230 fits in the annular groove 120 of the housing 100 and is in close contact with the annular groove 120. Therefore, the annular protrusion 230 has an outer shape and an outer size corresponding to the inner shape and inner size of the annular groove 120, respectively.

[0059] The annular protrusion 230 has a top surface with a substantially annular shape (e.g., a substantially circular or polygonal annular shape), a first wall surface with a substantially annular shape on the Y direction side, and a second wall surface with a substantially annular shape on the Y' direction side. The top surface of the annular protrusion 230 is in close contact with the bottom surface of the annular groove 120, the first wall surface of the annular protrusion 230 is in close contact with the first wall surface of the annular groove 120, and the second wall surface of the annular protrusion 230 is in close contact with the second wall surface of the annular groove 120.

[0060] In the case where the housing 100 includes at least one annular protrusion 130, the body 200 also includes at least one annular groove 240 (see FIG. 2A to FIG. 3B ). Depending on the number of the at least one annular protrusion 130, the at least one annular groove 240 may be a single groove or a plurality of grooves.

[0061] For ease of description, the at least one annular groove 240 is described below as a single annular groove 240 , but in the case where a plurality of annular grooves 240 are provided, each of the plurality of annular grooves 240 is configured similarly to a single annular groove.

[0062] The annular groove 240 is a recessed portion of a substantially annular shape (substantially circular or polygonal annular shape) provided in the outer peripheral surface of the body 200. The annular groove 240 is provided so that the central axis of the annular groove 240 substantially coincides with the central axis of the housing body 110 of the housing 100, and the annular groove 240 is recessed toward the central axis of the housing body 110 of the housing 100. In other words, the annular groove 240 is recessed relative to the annular protrusion 130 of the housing 100. The annular protrusion 130 of the housing 100 fits in the annular groove 240 and is in close contact with the annular groove 240. The annular groove 240 has an inner shape and an inner size corresponding to the outer shape and outer size of the annular protrusion 130, respectively.

[0063] The annular groove 240 includes a bottom surface having a substantially annular shape (e.g., a substantially circular or polygonal annular shape), a first wall surface having a substantially annular shape on the Y direction side, and a second wall surface having a substantially annular shape on the Y' direction side. The top surface of the annular protrusion 130 is in close contact with the bottom surface of the annular groove 240, the first wall surface of the annular protrusion 130 is in close contact with the first wall surface of the annular groove 240, and the second wall surface of the annular protrusion 130 is in close contact with the second wall surface of the annular groove 240.

[0064] The body 200 further includes a receiving hole 250 (see Figure 2A 3B). It is only necessary that the receiving hole 250 extends through the body 200 in the YY' direction. For example, the receiving hole 250 may extend through the body 210 in the YY' direction. The central axis of the receiving hole 250 may coincide with the central axis of the housing body 110.

[0065] The receiving hole 250 may include a first hole 251 and a second hole 252. The first hole 251 is a hole roughly shaped like a column (e.g., a column with a roughly circular or polygonal cross section), extending in the Y-Y' direction, and opening in the Y direction. The second hole 252 is a hole extending from the first hole 251 in the Y' direction, communicating with the first hole 251, and opening in the Y' direction. The size of the cross section of the first hole 251 along the X-X' direction and the Z-Z' direction is smaller than the size of the second hole 252.

[0066] The first hole 251 and the second hole 252 may be omitted. In this case, the receiving hole 250 may be a hole shaped substantially like a column (eg, a column of substantially circular or polygonal cross section) and extends in the YY' direction.

[0067] In the case where the housing 100 and the body 200 have the above configuration (1) or (2), the receiving hole 250 (specifically, if the receiving hole 250 is provided, the second hole 252 thereof) communicates with the hole 150 of the housing 100 (see Figure 2A and 2B ).

[0068] In the case where the housing 100 and the body 200 have one of the above configurations (3) to (6), the accommodation hole 250 (specifically, the second hole 252 thereof if the accommodation hole 250 is provided) opens in the Y′ direction (not shown).

[0069] The connector C1 also includes a terminal 300. The terminal 300 is made of a conductive material (e.g., a metal or a carbon material such as a carbon nanotube). The first terminal 300a can be arranged so that an imaginary line (not shown) extending through the center of the first terminal 300a in the Y-Y' direction substantially coincides with the central axis of the housing body 110. Therefore, the terminal 300 and the housing body 110 form a coaxial structure. The terminal 300 includes a distal portion 310, a middle portion 320, and a rear portion 330.

[0070] The middle portion 320 of the terminal 300 is a portion between the distal portion 310 and the rear portion 330. For example, the middle portion 320 has a generally tubular shape such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross section along the Z-Z' direction and the X-X' direction) and extends in the Y-Y' direction (see FIG. 2A to FIG. 3B ), a rod (not shown) extending in the Y-Y' direction, a plate (not shown) extending in the Y-Y' direction, etc. The middle part 320 is at least partially accommodated and held in the accommodation hole 250 of the body 200. In the case where the accommodation hole 250 of the body 200 includes the first hole 251 and the second hole 252, the middle part 320 is at least partially and firmly accommodated in the first hole 251 of the body 200. The external shape of the cross section of the middle part 320 along the X-X' direction and the Z-Z' direction is basically the same as the shape of the cross section of the accommodating hole 250 of the main body 200 (specifically, if the accommodating hole 250 is provided, then its first hole 251) along the X-X' direction and the Z-Z' direction, and the external dimensions of the cross section of the middle part 320 along the X-X' direction and the Z-Z' direction are generally equal to or slightly smaller than the dimensions of the cross section of the accommodating hole 250 of the main body 200 (specifically, if the accommodating hole 250 is provided, then its first hole 251) along the X-X' direction and the Z-Z' direction.

[0071] The distal portion 310 of the terminal 300 has a generally tubular shape such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross section along the Z-Z' direction and the XX' direction) and extends from the middle portion 320 along the Y direction (see FIG. 2A to FIG. 3B ) components, a pair of beams extending from the middle portion 320 along the Y direction (see Fig. 7A and 7B ), a rod (not shown) extending from the middle portion 320 along the Y direction, a plate (not shown) extending from the middle portion 320 along the Y direction, etc. The distal portion 310 may protrude from the receiving hole 250 of the body 200 along the Y direction and be disposed inside the housing body 110 (see FIG. 2A to FIG. 2B ), or alternatively, may be disposed in the receiving hole 250 of the body 200 and exposed from the receiving hole 250 along the Y direction (see to be described Fig. 6A and Figure 6B ).

[0072] The rear portion 330 of the terminal 300 has a generally tubular shape such as a generally circular or polygonal tubular shape (a generally tubular shape having a generally circular or polygonal cross section along the Z-Z' direction and the XX' direction) and extends from the middle portion 320 along the Y' direction (see FIG. 2A to FIG. 3B ) components, a rod (not shown) extending from the middle part 320 along the Y' direction, a plate (not shown) extending from the middle part 320 along the Y' direction, and the like.

[0073] In the case where the housing 100 and the body 200 have the above configuration (1) or (2), the rear portion 330 is disposed in the receiving hole 250 of the body 200 (specifically, if the receiving hole 250 is provided, the second hole 252 thereof) (see Figure 2A and Figure 2B ).

[0074] In the case where the shell 100 and the body 200 have one of the above-mentioned configurations (3) to (6), the rear portion 330 can be set in the receiving hole 250 of the body 200 (not shown) (specifically, if the receiving hole 250 is set, then its second hole 252) or, alternatively, can protrude from the receiving hole 250 of the body 200 (specifically, if the receiving hole 250 is set, then its second hole 252) along the Y' direction and be set inside the shell body 110 (not shown).

[0075] The terminal 300 may further include a first portion 301. The first portion 301 is a portion of the terminal 300 in the YY′ direction. The first portion 301 is disposed in the distal portion 310, the middle portion 320, or the rear portion 330 of the terminal 300.

[0076] The terminal 300 may further include at least one second portion 302 and / or at least one third portion 303. For ease of description, hereinafter, at least one second portion 302 is described as a single second portion 302, but in the case where a plurality of second portions 302 are provided, each of the plurality of second portions 302 is configured similarly to the single second portion 302. In addition, hereinafter, at least one third portion 303 is described as a single third portion 303, but in the case where a plurality of third portions 303 are provided, each of the plurality of third portions 303 is configured similarly to the single third portion 303.

[0077] The second portion 302 is another portion of the terminal 300 in the Y-Y' direction that does not include the first portion 301, and has a higher impedance than the first portion 301. The second portion 302 is disposed in the distal portion 310, the middle portion 320, or the rear portion 330 of the terminal 300. Among various factors that lead to the second portion 302 having a higher impedance than the first portion 301, one main factor is that the outer dimensions of the cross section of the second portion 302 along the X-X' direction and the Z-Z' direction are larger than the outer dimensions of the first portion 301. The larger the outer dimensions of the cross section of the second portion 302 along the X-X' direction and the Z-Z' direction are, the higher the impedance of the second portion 302 is.

[0078] The third part 303 is another part of the terminal 300 in the Y-Y' direction that does not include the first part 301, and has a lower impedance than the first part 301. In the case where the second part 302 and the third part 303 are provided, the second part 302 and the third part 303 are different parts of the terminal 300 in the Y-Y' direction. The third part 303 is provided in the distal part 310, the middle part 320 or the rear part 330 of the terminal 300. Among the various factors that cause the impedance of the third part 303 to be lower than that of the first part 301, a main factor is that the outer dimensions of the cross section of the third part 303 along the X-X' direction and the Z-Z' direction are smaller than the outer dimensions of the first part 301. The smaller the outer dimensions of the cross section of the second part 302 along the X-X' direction and the Z-Z' direction are, the lower the impedance of the second part 302 is.

[0079] One possible method of finding out the portion (second portion 302) having a higher impedance and / or the portion (third portion 303) having a lower impedance in the Y-Y' direction of the terminal 300 is to input the CAD data of the connector C1 into a high-frequency simulator to build a model, and then simulate based on information of the model or other information. Examples of high-frequency simulators include Femtet (registered trademark) and Ansys HFSS ("Ansys" is a registered trademark), Femtet is an application manufactured by Murata Software Co., Ltd., and Ansys HFSS is an application manufactured by Ansys, Inc.

[0080] In the case where the annular groove 120 of the housing 100 is provided, the annular groove 120 surrounds the second portion 302 of the terminal 300 and is recessed away from the second portion 302 (see Figure 2A and Figure 2B ). As the depth dimension of the annular groove 120 increases (the straight-line distance from the inner circumferential surface 113 of the shell body 110 of the shell 100 to the bottom surface of the annular groove 120 in a direction orthogonal to the Y-Y' direction (hereinafter referred to as the "orthogonal direction")), the straight-line distance from the bottom surface of the annular groove 120 to the second part 302 of the terminal 300 in the orthogonal direction increases, so as to reduce the impedance of the second part 302 of the terminal 300. Therefore, the depth dimension of the annular groove 120 can be determined according to the impedance of the second part 302 of the terminal 300. For example, CAD data of the connector C1 with different depth dimensions of the annular groove 120 can be input into a high-frequency simulator to construct a model, and multiple groups of simulations can be performed based on the information of the model and other information to determine the depth dimension of the annular groove 120 so that the impedance of the second part 302 of the terminal 300 is substantially the same as or close to the impedance of the first part 301 of the terminal 300. In addition to setting the depth dimension of the annular groove 120 , the shape of the portion of the body 200 located around the second portion 302 of the terminal 300 may also be changed so that the impedance of the second portion 302 of the terminal 300 is substantially the same as or close to the impedance of the first portion 301 of the terminal 300 .

[0081] In the case where the annular protrusion 130 of the housing 100 is provided, the annular protrusion 130 surrounds the third portion 303 of the terminal 300 and protrudes toward the third portion 303 (see Figure 2A and Figure 2B). As the height dimension of the annular protrusion 130 increases (the straight-line distance in the direction orthogonal to the Y-Y' direction from the inner circumferential surface 113 of the shell body 110 of the shell 100 to the top surface of the annular protrusion 130), the straight-line distance in the orthogonal direction from the top surface of the annular protrusion 130 to the third portion 303 of the terminal 300 decreases, so as to increase the impedance of the third portion 303 of the terminal 300. Therefore, the height dimension of the annular protrusion 130 can be determined according to the impedance of the third portion 303 of the terminal 300. For example, CAD data of the connector C1 with different height dimensions of the annular protrusion 130 can be input into a high-frequency simulator to construct a model, and multiple groups of simulations can be performed based on the information of the model and other information to determine the height dimension of the annular protrusion 130 so that the impedance of the third portion 303 of the terminal 300 is substantially the same as or close to the impedance of the first portion 301 of the terminal 300. In addition to setting the height dimension of the annular protrusion 130 , the shape of the portion of the body 200 located around the third portion 303 of the terminal 300 may also be changed so that the impedance of the third portion 303 of the terminal 300 is substantially the same as or close to the impedance of the first portion 301 of the terminal 300 .

[0082] Even in the case where the second part 302 of the terminal 300 is provided, the annular groove 120 of the housing 100 can be omitted. In the case where the annular groove 120 of the housing 100 is omitted, the annular protrusion 230 of the body 200 is also omitted. Even in the case where the third part 303 of the terminal 300 is provided, the annular protrusion 130 of the housing 100 can be omitted. In the case where the annular protrusion 130 of the housing 100 is omitted, the annular groove 240 of the body 200 is also omitted. The second part 302 of the terminal 300 can be omitted. In this case, the annular groove 120 of the housing 100 and the annular protrusion 230 of the body 200 can be omitted but not necessarily. The third part 303 of the terminal 300 can be omitted. In this case, the annular protrusion 130 of the housing 100 and the annular groove 240 of the body 200 can be omitted but not necessarily.

[0083] The connector C1 further includes a cable 400 . The cable 400 is partially received inside the housing body 110 from the Y′ direction side, and is connected to the rear portion 330 of the terminal 300 inside the housing body 110 .

[0084] The cable 400 is a coaxial cable and includes an outer insulator 410 , an outer conductor 420 , an inner insulator 430 , and an inner conductor 440 .

[0085] The outer insulator 410 is a generally tubular sheath made of an insulating material. The outer conductor 420 is a generally tubular member made of a conductor such as a copper wire mesh, and is disposed inside the outer insulator 410. In other words, the outer conductor 420 is covered by the outer insulator 410. The outer conductor 420 includes a distal portion on the Y direction side. The distal portion of the outer conductor 420 protrudes from the outer insulator 410 in the Y direction.

[0086] The inner insulator 430 is a tube made of an insulating material, and is disposed inside the outer conductor 420. The inner insulator 430 includes a distal portion on the Y direction side. The distal portion of the inner insulator 430 protrudes from the outer conductor 420 in the Y direction. The inner conductor 440 is a metal wire such as a copper wire, and is disposed inside the inner insulator 430. The inner conductor 440 includes a distal portion on the Y direction side. The distal portion of the inner conductor 440 protrudes from the inner insulator 430 in the Y direction.

[0087] In the case where the housing 100 and the body 200 have the above-mentioned configuration (1) or (2), the outer shape of the cross section of the distal portion of the inner insulator 430 of the cable 400 along the X-X' direction and the Z-Z' direction is substantially the same as the shape of the cross section of the hole 150 of the housing 100 along the X-X' direction and the Z-Z' direction, and the outer dimensions of the cross section of the distal portion of the inner insulator 430 of the cable 400 along the X-X' direction and the Z-Z' direction are substantially equal to or slightly smaller than the dimensions of the cross section of the hole 150 of the housing 100 along the X-X' direction and the Z-Z' direction (see Figure 2A and Figure 2B ). The distal portion of the inner insulator 430 of the cable 400 fits in the hole 150 of the housing 100. The distal portion of the inner conductor 440 of the cable 400 is received in the receiving hole 250 of the body 200 (specifically, the second hole 252 thereof if the receiving hole 250 is provided), and is connected to the rear portion 330 of the terminal 300 in the receiving hole 250 (specifically, the second hole 252 thereof if the receiving hole 250 is provided). In the case where the cable holder 160 of the housing 100 is provided, the distal portion of the outer conductor 420 of the cable 400 fits over the cable holder 160 and is connected to the cable holder (see Figure 2A and Figure 2B ). In the case where the cable holder 160 of the housing 100 is not provided, the distal portion of the outer conductor 420 of the cable 400 is in contact with and connected to the housing 100 (not shown).

[0088] In the case where the housing 100 and the body 200 have one of the above configurations (3) to (6) and the rear portion 330 of the terminal 300 is disposed in the receiving hole 250 (specifically, if the receiving hole 250 is provided, then the second hole 252 thereof) of the body 200 (not shown), the distal portion of the inner insulator 430 of the cable 400 and the distal portion of the inner conductor 440 of the cable 400 are received inside the housing body 110 of the housing 100 from the Y' direction side, and the distal portion of the inner conductor 440 of the cable 400 is connected to the rear portion 330 of the terminal 300 in the receiving hole 250 (specifically, if the receiving hole 250 is provided, then the second hole 252 thereof) of the body 200. The distal portion of the outer conductor 420 of the cable 400 can be in contact with and connected to the housing body 110.

[0089] In the case where the housing 100 and the body 200 have one of the above configurations (3) to (6) and the rear portion 330 of the terminal 300 protrudes (not shown) from the receiving hole 250 (specifically, if the receiving hole 250 is provided, the second hole 252 thereof) of the body 200 in the Y' direction, the distal portion of the inner insulator 430 of the cable 400 and the distal portion of the inner conductor 440 of the cable 400 are received inside the housing body 110 of the housing 100 from the Y' direction side, and the distal portion of the inner conductor 440 of the cable 400 is connected to the rear portion 330 of the terminal 300 inside the housing body 110. The distal portion of the outer conductor 420 of the cable 400 can be in contact with and connected to the housing body 110.

[0090] In the case where the cable holder 160 of the housing 100 is provided, the connector C1 may further include a conductive ring 500 (see Figures 1A to 3B ). The conductive ring 500 is composed of a conductor (e.g., a material such as metal) formed into a ring shape. The conductive ring 500 is fitted over the distal portion of the outer conductor 420 of the cable 400 (which is fitted above the cable holder 160) and the distal portion of the outer insulator 410 of the cable 400 on the Y direction side. The conductive ring 500 arranged in this way is fixed to the cable holder 160 via the distal portion of the outer conductor 420, and is also fixed to the distal portion of the outer insulator 410 of the cable 400. The conductive ring 500 may be, but is not necessarily, at least partially swaged so as to be fixed to the cable holder 160 via the outer conductor 420 and to the distal portion of the outer insulator 410 of the cable 400. The conductive ring 500 may be omitted.

[0091] The connector C1 may further include a housing 600 (see Figures 1A to 3B). The housing 600 is made of an insulating material (e.g., insulating resin, etc.). The housing 600 includes a housing body 610 and a connecting portion 620. The housing body 610 has a substantially rectangular tube extending along the Y-Y' direction (a substantially tubular shape having a substantially rectangular cross-section along the Z-Z' direction and the X-X' direction). The housing body 610 includes a housing space 611. The housing space 611 extends through the housing body 610 in the Y-Y' direction. The connecting portion 620 is a substantially tubular member extending from the housing body 610 along the Y direction. The interior of the connecting portion 620 is connected to the housing space 611 of the housing body 610.

[0092] The portion of the housing 100 on the Y' direction side is securely accommodated in the housing space 611 of the housing body 610. The portion of the housing 100 on the Y direction side is disposed in the connection portion 620. In the case where the conductive ring 500 is provided, the conductive ring 500 is provided in the housing space 611, and the cable 400 is led out of the housing space 611 along the Y' direction. In the case where the conductive ring 500 is not provided, the cable 400 is led out of the housing space 611 along the Y' direction.

[0093] The engaging hole 612 may be provided in the wall of the shell body 610 on the X' direction side. The engaging hole 612 includes a first hole on the Z direction side, a second hole on the Z' direction side, a coupling groove, a first engaging portion on the Z direction side, and a second engaging portion on the Z' direction side. The first hole and the second hole are provided in the wall of the shell body 610 on the X' direction side, extending along the X direction, respectively located on the Z direction side and the Z' direction side relative to the shell space 611, connected to the shell space 611, and open along the X direction. The coupling groove is provided in the wall of the shell body 610 on the X' direction side, and extends from the first hole to the second hole. The first engaging portion is an edge of the opening of the first hole on the X direction side on the Z' direction side, a protrusion on the edge, etc. The second engaging portion is an edge of the opening of the second hole on the X direction side on the Z direction side, a protrusion on the edge, etc.

[0094] The housing 600 may further include a locking portion 630. The locking portion 630 extends from the housing body 610 in the Y direction and along the connecting portion 620. The locking portion 630 is provided with a protrusion 631 protruding in the Z direction.

[0095] In the case where the engaging groove 170 of the housing body 110 of the housing 100 and the engaging hole 612 of the shell 600 are provided, the connector C1 may further include a retainer 700 (see Figures 1A to 3B). The retainer 700 is a substantially C-shaped member and includes a first engagement arm 710, a second engagement arm 710 and a coupling portion 720. The distance between the first engagement arm 710 and the second engagement arm 710 in the Z-Z' direction is slightly smaller than the distance from the portion on the Z-direction side to the portion on the Z'-direction side of the bottom of the engagement groove 170. The first engagement arm 710 extends from the end of the coupling portion 720 on the Z-direction side along the X-direction and includes a free end portion having a claw protruding to the Z'-direction side. The second engagement arm 710 extends from the end of the coupling portion 720 on the Z'-direction side along the X-direction and includes a free end portion having a claw protruding to the Z-direction side. The coupling portion 720 is received in the coupling groove of the engagement hole 612 of the housing 600. The first engagement arm 710 is received in the first hole of the engagement hole 612 of the housing 600, and the claw of the first engagement arm 710 is hooked on the first engagement portion of the engagement hole 612. The second engagement arm 710 is received in the second hole of the engagement hole 612 of the housing 600, and the claw of the second engagement arm 710 is hooked on the second engagement portion of the engagement hole 612. Therefore, the first engagement arm 710 and the second engagement arm 710 elastically hold the housing body 110 therebetween and are fixed to the housing 600.

[0096] Even in the case where the engagement hole 612 of the housing 600 and the retainer 700 are provided, the engagement groove 170 of the housing 100 may be omitted. In this case, the retainer 700 only needs to elastically retain the housing body 110. In addition, the engagement groove 170 of the housing 100, the engagement hole 612 of the housing 600, and the retainer 700 may be omitted. In addition to omitting the engagement groove 170 of the housing 100 and the retainer 700, the entire housing 600 may be omitted.

[0097] Hereinafter, a non-limiting method of manufacturing the connector C1 will be described in detail. Figure 4A A molding device for insert molding the body 200 inside the housing body 110 of the housing 100 is shown, and Figure 4B is an enlarged view of a portion α of the molding device.

[0098] First, the housing 100 including the housing body 110, the bottom 140, the hole 150 and the cable holder 160 is prepared. A housing holder H having a substantially tubular shape and extending in the Y-Y' direction is also prepared. The housing 100 is fitted into the housing holder H. In other words, the housing holder H is fitted over the housing 100.

[0099] The first mold 10 and the second mold 20 of the molding device are closed together, and the housing holder H and the housing 100 are accommodated in the cavities of the first mold 10 and the second mold 20 (see Figure 4A and Figure 4B). The first mold 10 includes a first insert 11 , and the second mold 20 includes a second insert 21 .

[0100] In the case where the first outermost end 201 of the body 200 is located on the Y' direction side relative to the distal end 111 of the shell body 110, when the first mold 10 and the second mold 20 are closed together, the first insert 11 is inserted into the shell body 110 from the Y direction side to block the shell body 110 with the first insert 11 from the Y direction side, and the second insert 21 is inserted into the hole 150 of the shell body 110 and the shell 100 from the Y' direction side so that the second insert 21 abuts against the first insert 11 and blocks the shell body 110 with the second insert 21 from the Y' direction. As a result, the shell body 110, the first insert 11, and the second insert 21 define an injection space, and the gate G in the first insert 11 communicates with the injection space. The injection space corresponds to the shape and size of the body 200 according to one of the above aspects. The portion of the second insert 21 inserted into the shell body 110 corresponds to the shape and size of the receiving hole 250 of the body 200. The portion of the second insert 21 inserted into the hole 150 is fitted in the hole 150 so that the housing body 110 is blocked from the Y' direction side by the second insert 21. The door G is a pin door, and includes an injection port provided inside the housing body 110 and communicating with the injection space. According to one aspect of the above aspects, the injection port of the door G may be communicated with a portion of the injection space corresponding to the distal side of the distal portion 211 of the main body 210 of the body 200. Alternatively, the injection port may be communicated with a portion of the injection space corresponding to the first outermost end 201 of the body 200, which is not the distal side of the distal portion 211 of the main body 210.

[0101] When the first outermost end 201 of the body 200 and the distal end 111 of the shell body 110 are located at substantially the same position in the Y-Y' direction, when the mold is closed together, the first insert 11 may not be inserted into the shell body 110 of the shell 100, but instead blocks the shell body 110 of the shell 100 from the Y direction side.

[0102] When the inner circumferential surface 113 of the housing body 110 is provided with the annular groove 120, the annular groove 120 forms a part of the injection space. When the inner circumferential surface 113 of the housing body 110 is provided with the annular protrusion 130, the annular protrusion 130 is provided in the injection space.

[0103] In the case where the cable holder 160 is omitted, when the molds are closed together, the second insert 21 can be inserted into the hole 150 of the bottom 140 of the housing 100 and the housing body 110 from the Y' direction side to abut on the first insert 11 and block the housing body 110 from the Y' direction side. Also in this case, the portion of the second insert 21 inserted into the hole 150 fits in the hole 150.

[0104] In the case where the bottom 140, the hole 150, and the cable holder 160 are omitted, when the mold is closed together, the second insert 21 can be inserted into the housing body 110 of the housing 100 from the Y' direction side to abut on the first insert 11 and block the housing body 110 from the Y' direction side. In this case, the second insert 21 includes a portion to be inserted into the housing body 110 and a portion blocking the housing body 110 from the Y' direction side.

[0105] The housing holder H may be omitted. In this case, when the molds are closed together, the cavity may accommodate only the housing 100 according to one of the above aspects.

[0106] After the mold is closed together, molten resin is injected through the gate G and filled into the injection space. Therefore, the filled molten resin adheres to the inner peripheral surface 113 of the housing body 110. In the case where the bottom 140 is provided, the filled molten resin also adheres to the first surface 141 of the bottom 140. In the case where the annular groove 120 is provided, the molten resin is also filled into the annular groove 120 and also adheres to the bottom surface, the first wall surface, and the second wall surface of the annular groove 120. In the case where the annular protrusion 130 is provided, the filled molten resin also adheres to the top surface, the first wall surface, and the second wall surface of the annular protrusion 130.

[0107] After the molten resin is filled, the molten resin is solidified by cooling or other means. As a result, the solidified molten resin becomes the body 200 insert-molded inside the housing body 110. In the case where the annular groove 120 is provided, the portion of the solidified molten resin located in the annular groove 120 becomes the annular protrusion 230 of the body 200 that fits into the annular groove 120. In the case where the annular protrusion 130 is provided, the solidified molten resin is formed with a recess having a shape corresponding to the annular protrusion 130 and becomes the annular groove 240 of the body 200.

[0108] After the molten resin is solidified, the first mold 10 and the second mold 20 are opened separately from each other, and the first insert 11 and the second insert 21 are removed from the housing 100 and the body 200. At this time, the portion of the second insert 21 that has been inserted into the housing body 110 is removed from the body 200, so that the receiving hole 250 is formed in the body 200. In the case where the housing 100 is provided with the bottom 140, the hole 150 and the cable holder 160, or alternatively, in the case where the housing 100 is provided with the bottom 140 and the hole 150 but without the cable holder 160, the receiving hole 250 in the body 200 communicates with the hole 150. In the case where neither the bottom 140, the hole 150 nor the cable holder is provided, the receiving hole 250 in the body 200 opens in the Y' direction through the housing body 110.

[0109] Before or after the body 200 is insert molded, the terminal 300 and the cable 400 are prepared. The distal portion of the inner conductor 440 of the cable 400 is connected to the rear portion 330 of the terminal 300. In the case where the conductive ring 500 is provided, the distal portion of the outer conductor 420 of the cable 400 is inserted into the conductive ring 500. In the case where the conductive ring 500 is not provided, this insertion step is omitted.

[0110] In the case where the housing 100 is provided with the bottom 140, the hole 150 and the cable holder 160, the terminal 300 connected to the cable 400 is inserted from the hole 150 of the housing 100 into the receiving hole 250 of the body 200. Therefore, the distal portion 310 of the terminal 300 is arranged in the receiving hole 250 of the body 200 and is exposed to the Y direction side, or alternatively, the distal portion 310 of the terminal 300 protrudes out of the receiving hole 250 of the body 200 in the Y direction and is arranged inside the housing body 110 of the housing 100. The middle portion 320 of the terminal 300 is arranged and at least partially retained in the receiving hole 250 of the body 200. The rear portion 330 of the terminal 300 is arranged in the receiving hole 250 of the body 200. After the terminal 300, the distal portion of the inner conductor 440 of the cable 400 is inserted from the hole 150 of the housing 100 into the receiving hole 250 of the body 200 and is arranged in the receiving hole 250. In the case where the terminal 300 is provided with the second portion 302, when the terminal 300 is held in the receiving hole 250 of the body 200, the second portion 302 is disposed inside the annular groove 120 of the housing 100. In the case where the terminal 300 is provided with the third portion 303, when the terminal 300 is held in the receiving hole 250 of the body 200, the third portion 303 is disposed inside the annular protrusion 130 of the housing 100. The distal portion of the inner insulator 430 of the cable 400 is fitted in the hole 150 of the housing 100 to block the hole 150. The distal portion of the outer conductor 420 of the cable 400 is fitted over the cable holder 160. In the case where the conductive ring 500 is provided, the conductive ring 500 is placed around the cable holder 160 by fitting the distal portion of the outer conductor 420 of the cable 400 over the cable holder 160. The conductive ring 500 is partially swaged so as to be in pressure contact with the cable holder 160 via the distal portion of the outer conductor 420 of the cable 400. Therefore, the conductive ring 500 is fixed to the cable holder 160 via the distal portion of the outer conductor 420 of the cable 400, and the distal portion of the outer conductor 420 of the cable 400 is electrically connected to the cable holder 160. In the case where the conductive ring 500 is not provided, the distal portion of the outer conductor 420 of the cable 400 is electrically connected to the cable holder 160 by fitting the distal portion of the outer conductor 420 of the cable 400 over the cable holder 160.

[0111] In the case where the housing 100 is provided with the bottom 140 and the hole 150 but is not provided with the cable holder 160, as described above, the terminal 300 is inserted from the hole 150 of the housing 100 into the receiving hole 250 of the body 200, the distal portion of the inner conductor 440 of the cable 400 is inserted from the hole 150 of the housing 100 into the receiving hole 250 of the body 200, and the distal portion of the inner insulator 430 of the cable 400 is fitted in the hole 150 of the housing 100 to block the hole 150. The distal portion of the outer conductor 420 of the cable 400 may or may not be in contact with the housing 100 and electrically connected.

[0112] In the case where the housing 100 is neither provided with the bottom 140, the hole 150 nor the cable holder 160, the terminal 300 connected to the cable 400 is inserted from the housing body 110 of the housing 100 into the receiving hole 250 of the body 200. Therefore, the distal portion 310 of the terminal 300 is arranged in the receiving hole 250 of the body 200 and is exposed to the Y direction side, or alternatively, the distal portion 310 of the terminal 300 protrudes out of the receiving hole 250 of the body 200 in the Y direction and is arranged inside the housing body 110 of the housing 100. The middle portion 320 of the terminal 300 is arranged and at least partially retained in the receiving hole 250 of the body 200. The rear portion 330 of the terminal 300 is arranged in the receiving hole 250 of the body 200. After the terminal 300, the distal portion of the inner conductor 440 of the cable 400 is inserted from the housing body 110 of the housing 100 into the receiving hole 250 of the body 200 and is disposed in the receiving hole 250. The distal portion of the outer conductor 420 of the cable 400 may or may not be in contact with and electrically connected to the housing 100.

[0113] In the case where the housing 600 is provided, the housing 600 is prepared after the terminal 300 and the cable 400 are assembled into the housing 100. Then, the housing 100 is inserted from the Y' direction side into the housing space 611 of the housing 600. As a result, the portion of the housing 100 on the Y direction side is inserted from the housing space 611 into the connecting portion 620, and the portion of the housing 100 on the Y' direction side is securely accommodated in the housing space 611 of the housing body 610.

[0114] Thereafter, the retainer 700 is prepared. The first engagement arm 710 and the second engagement arm 710 of the retainer 700 are respectively inserted into the first hole and the second hole of the engagement hole 612 of the housing 600 from the X' direction side. Then, the first engagement arm 710 and the second engagement arm 710 are respectively inserted into the part on the Z direction side and the part on the Z' direction side of the engagement groove 170 of the housing body 110 of the housing 100 and the housing body 110 is elastically held therebetween, and the first engagement arm 710 and the claws of the first engagement arm 710 are respectively hooked onto the first engagement portion and the second engagement portion of the engagement hole 612. In this way, the first engagement arm 710 and the second engagement arm 710 of the retainer 700 are fixed to the housing 600, and the housing body 110 is fixed to the housing 600. This is how the connector C1 is manufactured.

[0115] In the case where the housing 600 is provided but the holder 700 is not provided, the step of attaching the holder 700 to the housing 600 can be simply omitted. In the case where neither the housing 600 nor the holder 700 is provided, the step of assembling the housing 100 and other components into the housing 600 and the step of attaching the holder 700 to the housing 600 can be simply omitted.

[0116] The connector C1 and the method for manufacturing the connector C1 provide the following technical features and effects (1) to (7).

[0117] Technical features and effects (1): Connector C1 has improved EMI characteristics for the following reasons. The body 200 is insert molded inside the shell body 110 and is completely contained inside the shell body 110. The middle portion 320 of the terminal 300 is at least partially retained in the containing hole 250 of the body 200, and the terminal 300 is completely disposed inside the shell body 110. The cable 400 is connected to the rear portion 330 of the terminal 300 inside the shell body 110. Therefore, the entire terminal 300 and the portion where the terminal 300 and the cable 400 are connected together are disposed inside the shell body 110 and are shielded by the shell body 110, resulting in improved EMI characteristics of the connector C1. In addition, in the case where the shell body 110 is neither provided with a joint, a recess nor a through hole, the connector C1 has further improved EMI characteristics.

[0118] Technical features and effects (2): The connector C1 is easy to manufacture for the following reasons. The body 200 can be insert-molded in the housing body 110 because the body 200 is disposed inside the housing body 110 and is exposed to the Y-direction side. Since the body 200 is insert-molded in the housing body 110, the step of assembling the body 200 into the housing body 110 can be advantageously omitted. The body 200 is provided with a receiving hole 250, and simply by inserting the terminal 300 into the receiving hole 250, the middle portion 320 of the terminal 300 is at least partially held by the body 200. Therefore, it is easy to assemble the terminal 300 into the body 200. Therefore, the connector C1 is easy to manufacture.

[0119] Technical features and effects (3): If the body 200 is configured to be housed in the shell body 110 of the shell 100 and to be held by the shell body 110, one or more fine air layers may be generated in the interface between the body 200 and the shell body 110. The presence of one or more air layers on the periphery of a portion of the terminal 300 may cause the impedance of the portion of the terminal 300 to increase. The presence of one or more air layers may cause the gap between the body 200 and the shell body 110 of the shell 100 to increase, which may cause the body 200 to swing, positionally shift, etc. inside the shell body 110. In contrast, the connector C1 is configured so that the body 200 is insert-molded inside the shell body 110, wherein the outer peripheral surface of the body 200 is in close contact with the shell body 110. This configuration reduces the possibility of the generation of the above-mentioned air layer, thereby facilitating the impedance adjustment of the terminal 300. Furthermore, this configuration also results in a reduction in the gap between the body 200 and the housing body 110 of the housing 100 , thereby advantageously suppressing the swinging, positional displacement, etc. of the body 200 inside the housing body 110 .

[0120] Technical features and effects (4): In the case where the housing 100 is provided with at least one annular groove 120 and the terminal 300 is provided with a first portion 301 and at least one second portion 302 having an impedance higher than that of the first portion 301, it is easy to adjust the impedance of the terminal 300. Since the annular groove 120 or each annular groove 120 surrounds the second portion 302 or the corresponding second portion 302 of the terminal 300 and is recessed from the second portion 302 or the corresponding second portion 302 of the terminal 300, the impedance of the second portion 302 or each second portion 302 can be reduced so as to be substantially the same as or close to the impedance of the first portion 301 of the terminal 300. In addition, in the case where the housing 100 is manufactured by a machining process, the at least one annular groove 120 can be manufactured with high precision in terms of size, position, etc. This allows the at least one second portion 302 to be adjusted with high precision in impedance adjustment.

[0121] Technical features and effects (5): In the case where the housing 100 is provided with at least one annular protrusion 130 and the terminal 300 is provided with a first portion 301 and at least one third portion 303 having an impedance lower than that of the first portion 301, it is easy to adjust the impedance of the terminal 300. Since the annular protrusion 130 or each annular protrusion 130 surrounds the third portion 303 or the corresponding third portion 303 of the terminal 300 and protrudes toward the third portion 303 or the corresponding third portion 303 of the terminal 300, the impedance of the third portion 303 or each third portion 303 can be increased so as to be substantially the same as or close to the impedance of the first portion 301 of the terminal 300. In addition, in the case where the housing 100 is manufactured by a machining process, the at least one annular protrusion 130 can be manufactured with high precision in terms of size, position, etc. This allows the at least one third portion 303 to be adjusted with high precision in impedance adjustment.

[0122] Technical features and effects (6): In the case where the housing 100 is provided with at least one annular groove 120 and the body 200 is provided with at least one annular protrusion 230, and / or in the case where the housing 100 is provided with at least one annular protrusion 130 and the body 200 is provided with at least one annular groove 240, the position of the body 200 is restricted in the Y-Y' direction relative to the housing body 110 of the housing 100. This is because the annular protrusion 230 or each annular protrusion 230 of the body 200 fits in the annular groove 120 or the corresponding annular groove 120 of the housing body 110, and / or the annular protrusion 130 or each annular protrusion 130 of the housing body 110 fits in the annular groove 240 or the corresponding annular groove 240 of the body 200.

[0123] Technical features and effects (7): When the first outermost end 201 of the main body 200 is located on the Y' direction side relative to the distal end 111 of the shell body 110, when the mating connector is inserted into the connector C1 from the Y direction side, the connector C1 provides a larger allowable range for the connection of the mating connector in an inclined orientation or in an offset position in the X-X' direction and / or the Z-Z' direction relative to the connector C1.

[0124] Second embodiment

[0125] Now refer to FIG. 5A to FIG. 7B A connector C2 according to a plurality of embodiments of the present invention including the second embodiment and its variations is described. The connector C2 has a similar configuration to the connector C1, except that the connector C2 is a mating connector connectable to the connector C1. The differences between the connector C2 and the connector C1 will be described emphatically, and repeated descriptions will be omitted. FIG. 5A to FIG. 7B It also shows something like Figures 1A to 3B Y-Y' direction (first direction). FIG. 5A to FIG. 5B and FIG. 6B to FIG. 7B It also shows something like Figure 1A , Figure 1B and Figures 2B to 3B XX' direction (second direction). FIG. 5A to FIG. 6A and FIG. 7A to FIG. 7B It also shows something like Figures 1A to 2A and FIG. 3A to FIG. 3B Z-Z' direction (third direction).

[0126] The terminal 300 of the connector C2 has the same configuration as the terminal 300 of the connector C1, except that its distal portion 310 is connectable to the distal portion 310 of the terminal 300 of the connector C1. For example, one of the distal portion 310 of the terminal 300 of the connector C1 and the distal portion 310 of the terminal 300 of the connector C2 may have a concave shape (e.g., shaped like a pair of arms, having a generally tubular shape, etc.), and the other distal portion 310 may have a convex shape (e.g., shaped like a rod, a plate, etc.).

[0127] In the case where the distal portion 310 of the terminal 300 of the connector C1 protrudes from the receiving hole 250 of the body 200 of the connector C1 along the Y direction, the distal portion 310 of the terminal 300 of the connector C2 can be disposed in the receiving hole 250 of the body 200 of the connector C2 and exposed from the receiving hole 250 in the Y direction (see Fig. 6A and Figure 6B ).

[0128] With the distal portion 310 of the terminal 300 of the connector C1 disposed in the accommodating hole 250 of the body 200 of the connector C1 and exposed in the Y direction from the accommodating hole 250 , the distal portion 310 of the terminal 300 of the connector C2 may protrude in the Y direction from the accommodating hole 250 (not shown) of the body 200 of the connector C2.

[0129] In the case where the distal portion 310 of the terminal 300 of the connector C1 is disposed in the receiving hole 250 of the body 200 of the connector C1 and is exposed in the Y direction from the receiving hole 250, the distal portion 310 of the terminal 300 of the connector C2 may be disposed in the receiving hole 250 of the body 200 of the connector C2 and exposed in the Y direction from the receiving hole 250 (not shown). In this case, there is an annular gap between the distal portion 310 of the terminal 300 of the connector C2 and the distal portion 211 of the body 200 of the connector C2. In the case where the distal portion 310 of the terminal 300 of the connector C2 is connected to the distal portion 310 of the terminal 300 of the connector C1, the distal portion 211 of the body 200 of the connector C1 may be received in the annular gap around the distal portion 310 of the terminal 300 of the connector C2 in the receiving hole 250, but the opposite arrangement may also be adopted.

[0130] The terminal 300 of the connector C2 may or may not include the first portion 301 and the at least one second portion 302 and / or the at least one third portion 303 .

[0131] The distal portion of the housing body 110 of the connector C2 can removably receive the distal portion of the housing body 110 of the connector C1. The internal shape of the cross section of the distal portion of the housing body 110 of the connector C2 along the X-X' direction and the Z-Z' direction is substantially the same as the external shape of the cross section of the distal portion of the housing body 110 of the connector C1 along the X-X' direction and the Z-Z' direction. The internal dimensions of the cross section of the distal portion of the housing body 110 of the connector C2 along the X-X' direction and the Z-Z' direction are greater than the external dimensions of the cross section of the distal portion of the housing body 110 of the connector C1 along the X-X' direction and the Z-Z' direction. The housing body 110 of the housing 100 of the connector C2 may or may not include at least one annular groove 120 and / or at least one annular protrusion 130.

[0132] Regardless of whether the body 200 of the connector C2 includes the tube 220, there is a generally annular gap between the distal portion 211 of the main body 210 of the body 200 and the housing body 110. The tube 220 of the body 200 of the connector C2 (if provided) surrounds the base of the distal portion 211 of the main body 210 on the Y' direction side, wherein there is a generally annular gap therebetween. The body 200 of the connector C2 may or may not include at least one annular protrusion 230 and / or at least one annular groove 240.

[0133] The body 200 of the connector C2 may further include at least one abutment portion 260 instead of the at least one annular groove 240. Depending on the number of the at least one annular protrusion 130, the at least one abutment portion 260 may be a single abutment portion or a plurality of abutment portions.

[0134] For ease of description, hereinafter, at least one abutment portion 260 is described as a single abutment portion 260, but in the case where a plurality of abutment portions 260 are provided, each of the plurality of abutment portions 260 is configured similarly to the single abutment portion 260. In the case where the tube 220 is provided with the body 200, the abutment portion 260 may be constituted by a distal portion of the tube 220 on the Y direction side, or alternatively, by a portion of the body 210. In the case where the tube 220 is not provided with the body 200, the abutment portion 260 is constituted by a portion of the body 210. In either case, the abutment portion 260 abuts against the annular protrusion 130 from the Y' direction side.

[0135] In the case where the at least one annular protrusion 130 is a plurality of protrusions, the body 200 may further include at least one abutment portion 260 in addition to the at least one annular groove 240. The at least one abutment portion 260 may be omitted.

[0136] The connector C2 may further include a ground terminal 800. The ground terminal 800 includes a first ring 810, a second ring 820, and a plurality of contact springs 830. The first ring 810 and the second ring 820 are C-shaped or annular metal plates configured to reduce in diameter when elastically deformed, and are arranged in a spaced relationship from each other in the Y-Y' direction. The contact springs 830 are disposed between the first ring 810 and the second ring 820, and are arranged in a spaced relationship from each other along the circumferential direction of the first ring 810. Each of the contact springs 830 is bent into an arc shape so that its middle portion protrudes toward an imaginary line extending through the center of the first ring 810 and the second ring 820 in the Y-Y' direction. The ground terminal 800 is accommodated inside the housing body 110 of the housing 100, and surrounds the distal portion 211 of the body 210. The first ring 810 and the second ring 820 of the ground terminal 800 are in elastic contact with and electrically connected to the inner peripheral surface 113 of the housing body 110, and the contact spring 830 of the ground terminal 800 surrounds the distal portion 310 of the terminal 300 disposed in the receiving hole 250 of the body 200. In a state where the distal portion of the housing body 110 of the connector C1 is received inside the distal portion of the housing body 110 of the connector C2, the contact spring 830 of the ground terminal 800 is in elastic contact with the distal portion of the housing body 110 of the connector C1.

[0137] The ground terminal 800 may be omitted. In this case, with the distal portion of the housing body 110 of the connector C1 received inside the distal portion of the housing body 110 of the connector C2, the distal portion of the housing body 110 of the connector C2 and the distal portion of the housing 100 of the connector C1 may contact each other.

[0138] The connector C2 may include a housing 600 ′. As described below, the configuration of the housing 600 ′ of the connector C2 is different from the housing 600 of the connector C1 .

[0139] The housing 600' includes a housing body 610' and a tube 630'. The housing body 610' has a generally rectangular tube extending in the Y-Y' direction (a generally tubular shape having a generally rectangular cross-section along the Z-Z' direction and the X-X' direction). The housing body 610 includes a housing space 611'. The housing space 611' extends through the housing body 610' in the Y-Y' direction and is configured to removably accommodate the connecting portion 620 of the housing 600 of the connector C1. The tube 630' is a generally tubular member extending from the housing body 610' along the Y' direction. The interior of the tube 630' is connected to the housing space 611' of the housing body 610'.

[0140] The housing 100 is securely accommodated in the housing space 611' of the housing body 610'. When the conductive ring 500 is provided, the conductive ring 500 is provided in the housing space 611' and inside the tube 630', and the cable 400 is led out of the tube 630' along the Y' direction. When the conductive ring 500 is not provided, the cable 400 is led out of the tube 630' along the Y' direction.

[0141] In the case where the connector C2 is provided with the retainer 700, the housing body 610' of the connector C2 may further include an engagement hole 612 provided in the wall surface of the housing body 610' on the X' direction side. Similar to the connector C1, the connector C2 is configured such that the first engagement arm 710 and the second engagement arm 710 of the retainer 700 are fixed to the engagement hole 612 of the housing 600', and the housing body 110 is fixed to the housing 600'.

[0142] The housing 600' may further include a locking portion 640'.
