Description

[Technical field]

[0001] The present invention relates to an angle-type connector, and more particularly to a connector that mates with a mating connector along a mating axis. [Background technology]

[0002] Conventionally, connectors that are mounted on a board and mate with a mating connector along a mating axis parallel to the mounting surface of the board have been used. For example, Patent Document 1 discloses a so-called angle-type connector having an upper contact 1 and a lower contact 2 that are bent, as shown in FIG. 13. The upper contact 1 and the lower contact 2 are housed in insulating cylindrical housings 3 and 4, respectively, and the housings 3 and 4 are housed in conductive cylindrical shells 5 and 6. The angle-type connector is mounted on a board 7.

[0003] As shown in Figure 14, the upper contact 1 is formed of a metal plate having an approximately L-shape, and has a horizontal extension portion 1A that extends linearly in the mating direction with the mating connector, a contact portion 1B that extends linearly forward from the tip of the horizontal extension portion 1A along the mating direction, a downward extension portion 1C that extends linearly downward from the rear end of the horizontal extension portion 1A, and a mounting portion 1D that protrudes downward from the lower end of the downward extension portion 1C and is connected to a corresponding circuit pattern on the board 7. The upper contact 1 is held in the housing 3 by pressing the horizontally extending portion 1A into the insertion hole 3A of the housing 3 until the downwardly extending portion 1C abuts against the housing 3.

[0004] Like the upper contact 1, the lower contact 2 also has a horizontal extension portion 2A, a contact portion 2B, a downward extension portion 2C, and a mounting portion 2D, and the lower contact 2 is held in the housing 4 by pressing the horizontal extension portion 2A into the insertion hole 4A of the housing 4 until the downward extension portion 2C abuts against the housing 4.

[0005] Furthermore, in the connector described in Patent Document 1, the characteristic impedance of the connector is adjusted by forming bulging portions 1E and 2E that bulge backward on the downward extending portion 1C of the upper contact 1 and the downward extending portion 2C of the lower contact 2, respectively. The characteristic impedance of the connector can be adjusted by changing the bulging length of the bulging portions 1E and 2E; increasing the bulging length of the bulging portions 1E and 2E toward the rear reduces the characteristic impedance, and conversely, decreasing the bulging length of the bulging portions 1E and 2E increases the characteristic impedance.

[0006] [Patent Document 1] JP 2023-77187 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, since the bulges 1E and 2E formed to adjust the characteristic impedance of the connector are positioned downwardly toward the mounting portions 1D and 2D relative to the horizontal extension portions 1A and 2A that are pressed into the insertion holes 3A and 4A of the housings 3 and 4, even if one tries to push the upper contact 1 and the lower contact 2 from the rear to the front into the housings 3 and 4 using a tool, the posture of the upper contact 1 and the lower contact 2 becomes unstable, making it difficult to press in the upper contact 1 and the lower contact 2. In other words, the connector of Patent Document 1 has a problem in that it is not possible to achieve both adjustment of characteristic impedance and ease of assembly.

[0008] The present invention has been made to solve these conventional problems, and has an object to provide an angle-type connector that can achieve both adjustment of characteristic impedance and ease of assembly. [Means for solving the problem]

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. First embodiment 1 shows an angled coaxial connector 11 according to a first embodiment mounted on a substrate 21. The angled coaxial connector 11 is adapted to mate with a mating connector (not shown) along a mating axis C, and has one contact 12, an inner insulator 13 surrounding the contact 12, a conductive shell 14 surrounding the inner insulator 13, and an outer insulator 15 surrounding the shell 14.

[0016] The external insulator 15 has a concave mating connector accommodating portion 15A into which a portion of the mating connector is inserted when the angled coaxial connector 11 is mated with the mating connector, and a portion of each of the contacts 12, the internal insulator 13, and the shell 14 is exposed within the mating connector accommodating portion 15A. With the external insulator 15 disposed on the surface of the substrate 21, the angled coaxial connector 11 is mounted on the substrate 21.

[0017] For convenience, the surface of the substrate 21 extends along the XY plane, and the direction in which a part of the mating connector (not shown) is inserted into the mating connector accommodating portion 15A of the external insulator 15 is called the +Y direction, and the direction perpendicular to the surface of the substrate 21 is called the Z direction. The Y direction is the direction in which the fitting axis C extends.

[0018] 2 shows an assembly diagram of the angled coaxial connector 11. Along the mating axis C, the first shell 16 is disposed on the +Y side of the external insulator 15, the internal insulator 13 is disposed on the +Y side of the first shell 16, the contacts 12 are disposed on the +Y side of the internal insulator 13, and the second shell 17 is disposed on the +Y side of the contacts 12. The inner insulator 13 and the outer insulator 15 form an insulating housing 18 that holds the contacts 12, and the first shell 16 and the second shell 17 form a conductive shell 14 that is held in the housing 18 and surrounds the contacts 12.

[0019] As shown in Figure 3, the contact 12 is formed from a single metal plate punched into a roughly L shape, and has a press-in portion 12A extending linearly in the Y direction along the mating axis C, a contact portion 12B connected to the -Y direction tip of the press-in portion 12A, and a lead portion 12C connected to the +Y direction base end of the press-in portion 12A.

[0020] The contact portion 12B has a cylindrical shape that extends linearly in the −Y direction along the fitting axis C from the tip of the press-fit portion 12A. The lead portion 12C has a flat plate shape extending in the −Z direction perpendicular to the fitting axis C from the base end of the press-fit portion 12A. The contact 12 further has a pin-shaped mounting portion 12D that protrudes in the -Z direction from the tip of the lead portion 12C in the -Z direction.

[0021] A press-fitting force receiving surface 12E is formed at the +Z end and +Y end of the lead portion 12C, which is located on the fitting axis C and faces the +Y direction, which is the opposite direction to the contact portion 12B. The press-fitting force receiving surface 12E extends along the XZ plane perpendicular to the fitting axis C.

[0022] Here, the contact 12 is not formed by bending a metal plate into an L shape, but is formed from a metal plate punched into an L shape. Therefore, by applying a press-fitting force along the fitting axis C to the press-fitting force receiving surface 12E located on the fitting axis C, it is possible to press-fit and hold the contact 12 in the housing 18. In order to apply a press-fitting force along the fitting axis C to the press-fitting force receiving surface 12E, it is desirable for the press-fitting force receiving surface 12E to extend along an XZ plane perpendicular to the fitting axis C.

[0023] The contact 12 also has an impedance adjusting portion 12F disposed between the mounting portion 12D and the press-fit force receiving surface 12E of the lead portion 12C. The impedance adjusting portion 12F is formed by cutting out the middle portion in the Z direction of the end face of the lead portion 12C facing the +Y direction in the -Y direction at a position offset from the fitting axis C in the -Z direction perpendicular to the fitting axis C.

[0024] In this way, the press-fitting force receiving surface 12E and the impedance adjusting portion 12F are disposed at different positions from each other in the Z direction perpendicular to the fitting axis C. Therefore, it is possible to optimize the shape of the press-fitting force receiving surface 12E for receiving the press-fitting force along the fitting axis C and to optimize the shape of the impedance adjusting portion 12F for matching the characteristic impedance without mutual interference.

[0025] As shown in Figure 4, the width W1 of the lead portion 12C in the Y direction perpendicular to the Z direction in which the lead portion 12C extends is set wider than the width W2 of the contact portion 12B and the maximum width W3 of the press-fit portion 12A in the Z direction perpendicular to the mating axis C.

[0026] As shown in FIG. 5, the internal insulator 13 has a cylindrical portion 13A extending along the fitting axis C and an orthogonal extending portion 13B extending in the -Z direction perpendicular to the fitting axis C from the +Y direction portion of the cylindrical portion 13A. As shown in Fig. 6, the cylindrical portion 13A is formed with an insertion hole 13C that penetrates the internal insulator 13 along the fitting axis C and into which the press-fit portion 12A of the contact 12 is inserted. The insertion hole 13C has a width in the Z direction that is slightly narrower than the maximum width W3 of the press-fit portion 12A of the contact 12 shown in Fig. 4. In addition, the +Y direction portion of the cylindrical portion 13A and the orthogonal extending portion 13B are formed with a concave lead portion accommodating portion 13D that communicates with the insertion hole 13C and is open in the +Y and -Z directions.

[0027] As shown in Fig. 7, the first shell 16 is formed from a single bent metal plate, and has a cylindrical portion 16A extending along the fitting axis C, and a front plate portion 16B extending from the +Y end of the cylindrical portion 16A in the -Z direction along the XZ plane. The +X end of the front plate portion 16B is bent in the -Y direction to form a fixing portion 16C extending in the -Y direction along the YZ plane. Although not shown in Fig. 5, the -X end of the front plate portion 16B is also bent in the -Y direction like the +X end to form a fixing portion 16C extending in the -Y direction along the YZ plane.

[0028] As shown in FIG. 8, second shell 17 is formed from a single bent metal plate and has a curved portion 17A forming part of a cylinder centered on fitting axis C, a rear plate portion 17B extending along the XZ plane so as to cover the +Y direction end of curved portion 17A, and a pair of side plate portions 17C extending in the -Z direction along the YZ plane from the +X direction end and the -X direction end of curved portion 17A, respectively.

[0029] A plurality of spring contact portions 17D each extending in the -Y direction are protrudingly formed at the -Y direction end of the curved portion 17A, and a plurality of shell mounting portions 17E each protruding in the -Z direction are formed at the -Z direction ends of the pair of side plate portions 17C. Furthermore, the +X and -X ends of rear plate portion 17B are each bent in the -Y direction to form fixing portions 17F extending in the -Y direction along the YZ plane. Similarly, the -Y ends of the pair of side plate portions 17C each form fixing portions 17G protruding in the -Y direction along the YZ plane.

[0030] 9, the external insulator 15 has a housing body 15B having a rectangular parallelepiped outer shape, and a rear cover 15C connected to the +Y end of the housing body 15B. A mating connector accommodating portion 15A having a recessed shape that opens toward the -Y direction is formed inside the housing body 15B. A second shell accommodating portion 15D having a recessed shape that communicates with the mating connector accommodating portion 15A and that opens toward the +Y and -Z directions is formed inside the rear cover 15C.

[0031] When assembling the angled coaxial connector 11, first, the contacts 12 are moved from the +Y direction to the -Y direction toward the internal insulator 13, so that the contacts 12 are held in the internal insulator 13. At this time, the contact portion 12B and the press-fit portion 12A of the contacts 12 shown in Fig. 4 are inserted into the insertion hole 13C of the internal insulator 13 along the fitting axis C, and, for example, a force in the -Y direction is applied to the press-fit force receiving surface 12E of the contacts 12 located on the fitting axis C using a tool (not shown), so that the press-fit portion 12A is press-fitted into the insertion hole 13C.

[0032] Unlike the bulging portions 1E and 2E of the upper contact 1 and the lower contact 2 in the above-mentioned Patent Document 1, the impedance adjusting portion 12F of the contact 12 does not bulge in the +Y direction from the end face of the lead portion 12C facing the +Y direction, but is formed by cutting out the middle portion in the Z direction of the end face of the lead portion 12C facing the +Y direction toward the -Y direction. Therefore, it is possible to press the press-in portion 12A into the insertion hole 13C by applying a force in the -Y direction to the press-in force receiving surface 12E using a tool (not shown) without interference from the impedance adjusting portion 12F.

[0033] In addition, since the press-fitting force receiving surface 12E of the contact 12 is located on the mating axis C and extends along the XZ plane perpendicular to the mating axis C, a stable press-fitting can be performed by applying a force in the -Y direction to the press-fitting force receiving surface 12E. The press-fitting of the press-fit portion 12A into the insertion hole 13C is completed when the -Y direction end of the lead portion 12C shown in Fig. 4 hits the inner wall surface of the orthogonal extending portion 13B located at the -Y direction end of the lead portion accommodating portion 13D of the internal insulator 13 shown in Fig. 6. The contact portion 12B of the contact 12 protrudes in the -Y direction from the insertion hole 13C of the internal insulator 13.

[0034] Next, the first shell 16 is moved from the +Y direction to the -Y direction toward the external insulator 15, and the fixing portion 16C of the first shell 16 shown in Figure 7 is pressed into a fixed portion (not shown) inside the external insulator 15, thereby holding the first shell 16 to the external insulator 15.

[0035] In this manner, by moving the internal insulator 13 holding the contacts 12 from the +Y direction to the -Y direction relative to the first shell 16 held by the external insulator 15, the tubular portion 13A of the internal insulator 13 shown in Figure 5 is inserted into the cylindrical portion 16A of the first shell 16 shown in Figure 7, and the orthogonal extension portion 13B of the internal insulator 13 is positioned on the +Y direction side of the front plate portion 16B of the first shell 16.

[0036] Furthermore, by moving the second shell 17 from the +Y direction to the -Y direction relative to the first shell 16, the +Y direction portion and orthogonal extending portion 13B of the tubular portion 13A of the internal insulator 13 and the +Y direction end portion of the first shell 16 are covered by the second shell 17. The second shell 17 is held by the external insulator 15 by pressing the pair of fixing portions 17F and the pair of fixing portions 17G into fixed portions (not shown) inside the external insulator 15, respectively, thereby completing the assembly of the angled coaxial connector 11.

[0037] 10 shows a perspective view of the angled coaxial connector 11 assembled in this manner, viewed from diagonally below. The lead portions 12C of the contacts 12 are accommodated in the lead portion accommodating portions 13D of the internal insulator 13, and are surrounded by the front plate portion 16B of the first shell 16 and the rear plate portion 17B and a pair of side plate portions 17C of the second shell 17. Additionally, the mounting portion 12D of the contact 12 and a plurality of shell mounting portions 17E of the second shell 17 protrude from the outer insulator 15 in the -Z direction.

[0038] 11 shows a cross-sectional view of the angled coaxial connector 11 mounted on a substrate 21. The cylindrical portion 16A of the first shell 16 is disposed at the boundary between the housing main body 15B and the rear cover portion 15C of the external insulator 15 and passes through a through hole 15F formed in a partition portion 15E along the XZ plane, and extends from the second shell accommodating portion 15D of the rear cover portion 15C to the mating connector accommodating portion 15A of the housing main body 15B.

[0039] With the press-fit portion 12A inserted into the insertion hole 13C of the internal insulator 13 and the lead portion 12C accommodated in the lead portion accommodating portion 13D of the internal insulator 13, the contact 12 is surrounded by the cylindrical portion 16A and front plate portion 16B of the first shell 16, the curved portion 17A and rear plate portion 17B of the second shell 17, and a pair of side plate portions 17C shown in Figure 10. The second shell 17 is electrically connected to the first shell 16 by a plurality of spring contact portions 17D elastically contacting the outer circumferential surface of the cylindrical portion 16A of the first shell 16.

[0040] The substrate 21 has a through hole 21A that penetrates the substrate 21 in the Z direction and has a conductive layer such as a plating layer formed on its inner wall surface, corresponding to the mounting portion 12D of the contact 12. The mounting portion 12D of the contact 12 is passed through the through hole 21A and soldered, thereby being electrically connected to a wiring layer (not shown) of the substrate 21 that is connected to the through hole 21A.

[0041] Similarly, the substrate 21 has a plurality of through holes corresponding to the plurality of shell mounting portions 17E of the second shell 17, and each shell mounting portion 17E is passed through a corresponding through hole of the substrate 21 and soldered thereto, thereby being electrically connected to a ground layer (not shown) of the substrate 21 that is connected to the through hole.

[0042] The lead portion 12C of the contact 12 has an impedance adjustment portion 12F configured by cutting out the middle portion in the Z direction of the end face of the lead portion 12C facing the +Y direction. Therefore, by selecting the Y direction depth and Z direction length of the cutout in the impedance adjustment portion 12F, the characteristic impedance of the lead portion 12C can be adjusted, improving the signal transmission characteristics and enabling stable high-speed transmission.

[0043] The contact 12 is formed from a metal plate punched into an L shape, and has an impedance adjustment portion 12F formed by cutting out toward the -Y direction an end face facing the +Y direction of the lead portion 12C at a position deviated in the -Z direction from the fitting axis C. Therefore, without interference from the impedance adjustment portion 12F, a press-in force along the fitting axis C can be applied to the press-in force receiving surface 12E located on the fitting axis C, thereby press-fitting the press-in portion 12A into the insertion hole 13C of the internal insulator 13, and the angled coaxial connector 11 can be easily assembled.

[0044] In addition, since the press-fitting force receiving surface 12E and the impedance adjustment portion 12F of the contact 12 are arranged at different positions from each other along the Z direction perpendicular to the fitting axis C, the shape of the press-fitting force receiving surface 12E and the shape of the impedance adjustment portion 12F can be optimized without interfering with each other. In other words, it is possible to achieve both adjustment of the characteristic impedance of the angled coaxial connector 11 and ease of assembly.

[0045] In the above embodiment 1, the shell 14 surrounding the internal insulator 13 is composed of two parts, the first shell 16 and the second shell 17, but this is not limited to this, and the internal insulator 13 can also be surrounded by a shell consisting of a single part. However, if shell 14 is formed from first shell 16 and second shell 17 as in the first embodiment, angled coaxial connector 11 can be assembled efficiently.

[0046] Similarly, in the above embodiment 1, the housing 18 that holds the contacts 12 is composed of two parts, the internal insulator 13 and the external insulator 15, but this is not limited to this, and the contacts 12 can also be held by a housing consisting of a single part. However, if the housing 18 is formed by the internal insulator 13 and the external insulator 15 as in the first embodiment, the angled coaxial connector 11 can be assembled efficiently.

[0047] In the above embodiment 1, the lead portion 12C of the contact 12 extends from the base end of the press-in portion 12A toward the -Z direction perpendicular to the mating axis C, but the lead portion 12C is not limited to a direction perpendicular to the mating axis C, and it is sufficient if it extends in a direction intersecting the mating axis C.

[0048] Embodiment 2 In the above-mentioned first embodiment, the angled coaxial connector 11 is configured by applying the present invention to a coaxial connector, but the present invention is not limited to this. 12 shows an assembly diagram of an angled differential signal connector 31 according to embodiment 2. Along the mating axis C, a first shell 36 is disposed on the +Y side of an external insulator 35, an internal insulator 33 is disposed on the +Y side of the first shell 36, a pair of contacts 32 is disposed on the +Y side of the internal insulator 33, and a second shell 37 is disposed on the +Y side of the pair of contacts 32.

[0049] The inner insulator 33 and the outer insulator 35 form an insulating housing 38 that holds a pair of contacts 32, and the first shell 36 and the second shell 37 form a conductive shell 34 that is held in the housing 38 and surrounds the pair of contacts 32. The pair of contacts 32 are for transmitting differential signals, and are configured to be held by an internal insulator 33 with a predetermined gap between them in the X direction.

[0050] Each of the pair of contacts 32 has a configuration similar to that of the contact 12 in the first embodiment shown in Figures 3 and 4. That is, the contact 32 is formed from a single metal plate punched into a roughly L shape, and has a press-fit portion extending linearly in the Y direction along the fitting axis C, a contact portion connected to the -Y direction tip of the press-fit portion, a lead portion connected to the +Y direction base end of the press-fit portion, and a mounting portion protruding in the -Z direction from the -Z direction tip of the lead portion.

[0051] Furthermore, similar to contact 12 in embodiment 1, the +Y direction end of the lead portion of contact 32 is formed with a press-fitting force receiving surface located on the mating axis C and facing the +Y direction, and an impedance adjustment portion located off the mating axis C in the -Z direction and cut out toward the -Y direction.

[0052] When assembling the angled differential signal connector 31, similarly to the angled coaxial connector 11 of the first embodiment, first, the pair of contacts 32 is held in the internal insulator 33. Next, the first shell 36 is held in the external insulator 35, and the internal insulator 33 holding the pair of contacts 32 is covered with the first shell 36 and the second shell 37, thereby assembling the angled differential signal connector 31.

[0053] Here, each of the pair of contacts 32 has an impedance adjustment portion in which the +Y end of the lead portion is cut out toward the -Y direction at a position offset from the mating axis C in the -Z direction.Therefore, the contacts 32 can be pressed into and held in the internal insulator 33 by applying a force along the mating axis C to the press-fit receiving surface located on the mating axis C without interference from the impedance adjustment portion, making it possible to easily assemble the angled differential signal connector 31.

[0054] In this way, by applying the present invention to a differential signal connector, an angled differential signal connector 31 can be configured that is capable of achieving both adjustment of characteristic impedance and ease of assembly.

[0055] In addition, in embodiment 2, the shell 34 surrounding the internal insulator 33 is composed of two parts, the first shell 36 and the second shell 37, but this is not limited to this, and the internal insulator 33 can also be surrounded by a shell consisting of a single part.
