Description

Connector for differential signal transmission cable and shell structure thereof
Technical Field
The present invention relates to a housing structure of a connector for a differential signal transmission cable, and more particularly to a housing structure of a connector for transmitting a high-frequency differential signal.
Background
Fig. 7 is a diagram showing an example of a housing structure 700 of a conventional differential signal transmission cable connector, fig. 7 (a) is a plan view of the housing structure 700 of the conventional example, and fig. 7 (B) is a cross-sectional view of the housing structure 700 of fig. 7 (a) cut along line B-B. As shown in fig. 7 (a) and 7 (B), the conventional housing structure 700 includes a housing main body 710, a connector inner housing 720, and a differential signal transmission cable 730.
The case body 710 is a cylindrical member made of metal having a predetermined length, and includes an inner case housing part 711 and a cable housing part 712. The connector inner housing 720 is disposed inside the inner housing accommodating portion 711. The differential signal transmission cable 730 has one or more pairs of internal wires 731, and the periphery of the internal wires 731 is surrounded by copper foil 732. The periphery of copper foil 732 is surrounded by braided wire 733. A metal ferrule 734 is covered around the braided wire 733, and the braided wire 733 is folded back around the ferrule 734. In this state, the differential signal transmission cable 730 is inserted into the cable housing portion 712 of the housing main body portion 710, and the internal wire 731 is introduced into the connector inner housing 720.
At this time, a hollow 740 is generated between the intermediate portion of the inner housing part 711 and the cable housing part 712 in the housing main body part 710, and the connector inner housing 720, the internal wire 731, the braided wire 733, and the ferrule 734. Due to the presence of the hollow portion 740, when a high-frequency signal flows through the differential signal transmission cable 730, there is a problem that the characteristic impedance and the return loss decrease.
Conventionally, in order to eliminate the hollow portion 740 or reduce the adverse effect of the hollow portion 740, the distance between the internal wires 731 or the distance between the internal wires 731 and the external conductor (i.e., the case main body portion 710 and the braided wire 733) is adjusted by inserting a conductor or an insulator outside the internal wires 731.
For example, patent document 1 discloses a plug connector structure in which at least one pair of wires for differential signal transmission are separated from each other by a distance greater than that of a cable portion with an outer covering at widened portions, and a sleeve for applying pressure to reduce the distance between the pair of wires is provided at the widened portions.

Detailed Description
Hereinafter, a housing structure of a differential signal transmission cable connector according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an external perspective view of a housing 110 included in the housing structure of the differential signal transmission cable connector according to the present embodiment. In the following description, the direction of extension of the shell 110 is referred to as a longitudinal direction, and the direction perpendicular to the longitudinal direction is referred to as a radial direction. In fig. 1, the side of the housing 110 attached to the connector for the differential signal transmission cable, i.e., the left side of the drawing, is referred to as the front in the longitudinal direction, and the side of the housing to which the differential signal transmission cable is connected, i.e., the right side of the drawing, is referred to as the rear in the longitudinal direction.
As shown in fig. 1, the housing 110 is composed of a cylindrical main body 120, a pressing portion 130 formed on the longitudinal direction rear side of the main body 120, and a pressure contact cylinder portion 140 further formed on the longitudinal direction rear side of the pressing portion 130. The body portion 120 is a hollow member having a predetermined length in the longitudinal direction and a predetermined thickness in the radial direction, and an inner housing accommodating portion 121 is provided on the opposite side in the longitudinal direction, i.e., on the front side in the longitudinal direction on which the pressing portion 130 is provided, and is capable of accommodating an inner housing of a connector for a differential signal transmission cable (not shown). As described later, the inner case is inserted from the pressing portion 130 side. The main body 120 is formed by: the flat metal plate is rolled into a cylindrical shape, and both ends of the flat metal plate are connected to each other at a seam 123 substantially parallel to the longitudinal direction.
The pressing portion 130 is formed at one end of the body portion 120 on the rear side in the longitudinal direction, and constitutes a cable receiving opening 132. The pressing portion 130 has a notch 131. The slit 131 is continuous with the seam 123 of the body 120, and has a shape in which a connection point with the seam 123 is a vertex and two opposing sides 133 are opened in a V shape. When the pressing portion 130 is pressed by a pressing process described later, the two opposing edges 133 are in a parallel positional relationship and joined to each other.
The pressure-contact cylindrical portion 140 extends rearward in the longitudinal direction from a position of the pressing portion 130 different from the position where the notch 131 is formed, for example, a position facing the notch 131 in the radial direction, and the pressure-contact cylindrical portion 140 includes: a narrow first connecting portion 141 (see fig. 4D) extending from the end portion on the rear side in the longitudinal direction of the pressing portion 130, a braided portion tube 142 and a covering portion tube 143 connected to the first connecting portion 141, and a narrow second connecting portion 144 (see fig. 4D) connecting the braided portion tube 142 and the covering portion tube 143.
The first connection portion 141 extends rearward in the longitudinal direction from a portion of the end portion on the rear side in the longitudinal direction of the pressing portion 130, which portion is radially opposed to the portion where the slit 131 is formed, and the knitting portion tube 142 is further connected to the first connection portion 141. The braided part tube 142 includes: a knitting section tube bottom section 142A whose longitudinal direction front side is connected to the first connection section 141; and a pair of braided part holding pieces 142B, 142B extending symmetrically in a direction perpendicular to the longitudinal direction from the braided part cylinder bottom part 142A, and a braided wire part of the differential signal transmission cable from which the cable sheath is removed can be accommodated between these braided part holding pieces 142B, 142B. The lengths of the pair of braided part gripping pieces 142B, 142B extending in the direction perpendicular to the longitudinal direction may be equal to each other or different lengths as long as they can grip the braided wire portion of the differential signal transmission cable.
A second connecting portion 144 extends from the knitting portion tube bottom portion 142A of the knitting portion tube 142 to the rear side in the longitudinal direction, and a covering portion tube 143 is connected to the rear side in the longitudinal direction of the second connecting portion 144. The sheathing cylinder 143 includes: a covering cylinder bottom 143A whose longitudinal front side is connected to the second connection section 144; and a pair of cover gripping pieces 143B, 143B extending symmetrically in a direction perpendicular to the longitudinal direction from the cover cylinder bottom 143A, and between these cover gripping pieces 143B, a portion of the differential signal transmission cable from which the cable sheath is not removed can be accommodated. Similarly to the braided part gripping pieces 142B, the lengths of the pair of covering part gripping pieces 143B, 143B extending in the direction perpendicular to the longitudinal direction may be equal to each other or different as long as they can grip the cable sheath of the differential signal transmission cable.
Fig. 2 is an exploded external perspective view of the case structure 100 of the present embodiment including the case 110 of fig. 1. As shown in fig. 2, the shell structure 100 includes an inner housing 200, a differential signal transmission cable 300, a contact 400, and a ferrule 500, in addition to the shell 110 described above.
The inner case 200 is constituted by: four passages 210 parallel to the longitudinal direction are formed in a cylindrical insulator having a predetermined length in the longitudinal direction and a size in the radial direction, which can be inserted into the body portion 120 of the housing 110. Each passage 210 is composed of an inner wire housing passage 211 and a contact housing passage 212, and the radial outside of each passage 210 communicates with the outside, and a contact described later and an inner wire connected thereto can be inserted into the passage 210 from the radial outside or the rear in the longitudinal direction. In addition, the radially outer side of the passage 210 may not communicate with the outside, and in this case, the contact and the internal electric wire connected thereto are inserted into the passage 210 from the longitudinal direction rear side of the inner housing 200. The number of the passages 210 may be 2 or 8, depending on the number of the internal wires of the differential signal transmission cable 300 connected to the housing structure 100.
The differential signal transmission cable 300 includes 2 pairs of 4 internal wires 310 in total in the present embodiment. The inner wires 310 are twisted with each other inside the cable, and the entire circumference of the inner wires 310 is surrounded by the copper foil 320 (see fig. 3B), thereby protecting the twisted inner wires 310 from unraveling. The outer periphery of the copper foil 320 is surrounded by a braided wire 330 made of metal, and constitutes an outer conductor with respect to the inner wire 310. The metal braided wire 330 is surrounded by a cable sheath 340 made of resin.
As shown in fig. 2, a contact 400 is connected to the conductor of each inner wire 310. The contact 400 is a female contact that receives a male contact of a mating connector in the present embodiment, but may be a male contact. The inner wire 310 and the contact 400 are accommodated in the inner wire accommodating passage 211 and the contact accommodating passage 212 of the inner housing 200, respectively, as described above.
The ferrule 500 is a hollow cylindrical member made of metal having a predetermined length in the longitudinal direction. In the present embodiment, the ferrule 500 is fitted around the copper foil 320 of the differential signal transmission cable 300 and radially inside the braided wire 330. The assembling step will be described later. When the differential signal transmission cable 300 is inserted into the housing 110 and the pressing portion 130 is pressed, the ferrule 500 mechanically protects the inner wire 310 located at the radially inner side than the ferrule 500, and at the same time, the physical contact state between the braided wire 330 and the housing 110 is improved, and the electrical conduction state is improved.
Next, an assembly process of the case structure 100 of the present embodiment will be described with reference to fig. 3 to 5. As shown in fig. 3 (a), a cut is cut into a portion of the cable sheath 340 of the differential signal transmission cable 300, which is a predetermined length from the cable end, and the cable sheath 340 is peeled off. Fig. 3 (a) shows a state in which only the cable sheath 340 is peeled off from the differential signal transmission cable 300 and the braided wire 330 inside is visible.
Next, as shown in fig. 3 (B), the exposed braided wire 330 is folded back toward the longitudinal direction rear side toward the outside of the cable sheath 340. Then, the copper foil 320 located radially inward of the braided wire 330 is exposed. The copper foil 320 is cut at a portion separated by a predetermined length from the cable end, and the internal electric wires 310 are exposed.
Next, as shown in fig. 3 (C), the covering of the inner wire 310 is removed from the cable end by a predetermined length, and the conductor 311 is exposed. Further, as shown in fig. 3 (D), the connection contact 400 is pressed against the exposed conductor 311. Although a detailed description is omitted here, the contact 400 includes a female contact portion for receiving a male contact of a mating connector and a connecting portion including grip pieces for pressure-connecting the conductors 311, and the conductors 311 are inserted between the grip pieces and the grip pieces are pressed to perform pressure-connecting.
Next, as shown in fig. 3 (E), a ferrule 500 is attached around the copper foil 320. Further, as shown in fig. 3 (F), the contact 400 and the inner wire 310 connected to the contact 400 are inserted into the inner housing 200. Specifically, the contact 400 is inserted into the contact accommodating passage 212 of the inner housing 200, and the internal wire 310 is inserted into the internal wire accommodating passage 211 of the inner housing 200.
Next, as shown in fig. 3 (G), the braided wire 330 folded back to the rear in the longitudinal direction on the cable sheath 340 is folded back again to the front in the longitudinal direction so as to cover the periphery of the ferrule 500. Thereby, the front end portion of the braided wire 330 reaches the longitudinal direction rear end portion of the inner case 200.
Next, the differential signal transmission cable 300, the inner housing 200, and the ferrule 500 assembled in the above-described steps are inserted from the rear toward the front in the longitudinal direction with respect to the housing 110. Fig. 4 (a) is a perspective view of the case structure 100 before the pressing process for inserting the differential signal transmission cable 300 into the case 110, fig. 4 (B) is a plan view of an assembly of the case structure 100 of fig. 4 (a), fig. 4 (C) is a side view of the assembly of the case structure 100 of fig. 4 (a), and fig. 4 (D) is a cross-sectional view taken along the line D-D of fig. 4 (B).
At this time, since the pressing portion 130 of the case 110, on which the covering tube 143, the braided tube 142, and the slit 131 are provided, is in the open state before the pressing process, the differential signal transmission cable 300, the braided wire 330 of the differential signal transmission cable 300, and the inner case 200 can be easily inserted into the case 110. Through this insertion process, the inner housing 200 connected to the differential signal transmission cable 300 is positioned in the inner housing accommodating portion 121 of the housing 110. The cable sheath 340 of the differential signal transmission cable 300 is positioned between the pair of covering grip pieces 143B, 143B of the covering tube 143 of the case 110, and the braided wire 330 is positioned between the pair of braided grip pieces 142B, 142B of the braided tube 142 of the case 110.
As is apparent from fig. 4 (D), the braided wire 330 is interposed between the pressing portion 130 of the case 110, the inner case 200, the inner wire 310, and the ferrule 500, and fills the portion.
Next, as shown in fig. 5, the pressing portion 130, the braided portion tube 142, and the covering portion tube 143 of the case 110 are pressed by a pressing tool. Fig. 5 (a) is a perspective view of the differential signal transmission cable 300 inserted into the housing 110 and subjected to the compression processing, fig. 5 (B) is a plan view of the assembly of the housing structure 100 after the compression processing of fig. 5 (a), fig. 5 (C) is a side view of the assembly of the housing structure 100 after the compression processing of fig. 5 (a), and fig. 5 (D) is a cross-sectional view taken along the line D-D of fig. 5 (B).
At this time, the pressing portion 130 of the case 110 and the braided part tube 142 are simultaneously subjected to the pressing process in the same process. Thus, the two opposing sides 133 of the slit 131 of the pressing portion 130 are opened in a V shape before the pressing process, but are brought into contact with each other and closed after the pressing process. Further, since the pressing process is performed so that the opposing sides 133 opened in the V shape come into contact with each other, the pressing portion 130 is deformed from the cylindrical shape before the pressing process to the truncated cone shape (compare fig. 4 (D) with fig. 5 (D)). In the present embodiment, the case where the opposing sides 133 are joined in parallel to each other has been described, but they may be pressed so as to overlap each other. Further, the braided part tube 142 is contracted in diameter so that the two braided part gripping pieces 142B partially overlap each other, and the braided wire 330 inside is firmly gripped. Similarly, the sheath tube 143 is contracted in diameter so that the two sheath gripping pieces 143B partially overlap each other, and the cable sheath 340 inserted inside is firmly gripped.
By this pressing process, the pressing portion 130 of the case 110 is contracted into a truncated cone shape and is brought into close contact with the braided wire 330 inserted inside, and therefore, the pressing portion 130 of the case 110, the inner case 200, the inner wire 310, and the ferrule 500 are in a state of being occupied by the braided wire 330, and a state of leaving almost no space.
This makes it possible to keep the distance between the inner wire 310 and the outer conductor such as the case 110 or the braided wire 330 and the electrical characteristics between them constant without using a new member.
Fig. 6 is a diagram showing performance in comparison between the case of using the connector using the shell 110 of the differential signal transmission cable connector according to the present embodiment and the case of using the shell structure of the conventional differential signal transmission cable connector, where fig. 6 (a) shows a change in characteristic impedance and fig. 6 (B) shows a change in return loss.
As shown in fig. 6 (a), when the characteristic impedance of the connector for a differential signal transmission cable using the housing structure 100 of the present embodiment is designed to be 100 Ω, the specific impedance of the connector using the housing 110 of the present embodiment is improved as compared with the connector using the conventional housing structure. As shown in fig. 6 (B), in the case of the connector using the shell structure 100 of the present embodiment, for example, the return loss at a high frequency of 1GHz or more is improved as compared with the conventional connector.
