Description

[Technical Field]

[0001] The present invention relates to a shield to be assembled to a communication connector, a communication connector, and a metal plate in a developed view. [Background technology]

[0002] The communication connector is fitted with a noise-preventing shield that covers a housing that accommodates a communication terminal portion.

[0003] Patent Document 1 discloses a rectangular box-shaped shield formed by bending a metal plate and having two open sides. The shield in Patent Document 1 covers the top surface, each widthwise side, and rear surface of a rectangular parallelepiped housing of a connector. When unfolded, such a shield is roughly T-shaped.

[0004] A shield formed by bending a metal plate is manufactured, for example, by progressive press working, which repeats the process of feeding a coiled metal plate at a predetermined feeding pitch and punching it with a die. In a roughly T-shaped development such as that in Patent Document 1, when feeding is performed at a predetermined feeding pitch in the vertical direction of the T-shaped letter and punching it with a die, the feeding pitch is determined based on the dimensions of the development in the vertical direction of the T-shape.

[0005] In progressive press processing, shortening the dispensing pitch of the coiled metal plate shortens the dispensing takt time, allowing for an increase in the number of punches per unit time using the die, and also reduces the amount of material used. [Prior art documents] [Patent documents]

[0023] [First embodiment] Hereinafter, a communication connector 1 in which a shield 10 formed by bending a metal plate according to a first embodiment of the present invention is assembled into a housing 100, and the shield 10 will be described with reference to the accompanying drawings. For ease of explanation, as shown in each drawing, a first direction Z, a second direction Y perpendicular to the first direction Z, and a third direction X perpendicular to the first direction Z and the second direction Y are defined. In addition, the upper side of the first direction Z is defined as (U), the lower side is defined as (D), the right side of the second direction Y is defined as (R), the left side is defined as (L), and the front side of the third direction X is defined as (F) and the rear side is defined as (B). In Figure 3, the direction in which the coiled metal plate is dispensed is the dispensing direction P, which is the fifth direction, and the direction perpendicular to the dispensing direction P is the width direction W, which is the fourth direction. Also, the upstream of the dispensing direction P is (US), and the downstream is (DS).

[0024] [Communication connector 1: See Figures 1 and 4] 1, the communication connector 1 includes a shield 10 formed by bending a metal plate, a housing 100 to which the shield 10 is attached, and a plurality of contact portions 110. The communication connector 1 is mated with a mating connector (not shown), and the contact portions of the mating connector are electrically connected to the contact portions 110. When the communication connector 1 is mounted on a board, the contact portions 110 are electrically connected to the contact portions of the board, and the communication connector 1 relays communication signals to the board.

[0025] [Shield 10: See Figures 1 and 2] 1 and 2, shield 10, formed by bending a metal plate, has multiple bent portions formed by bending the metal plate in the same direction, and includes multiple shield portions adjacent to each other with the bent portions sandwiched between them. Shield 10 is composed of a first shield portion 11 covering the upper U side of housing 100 in the first direction Z, a second shield portion 12 covering the left L side of housing 100 in the second direction Y, a fourth shield portion 14 covering the right R side of housing 100 in the second direction Y, a third shield portion 13 and a fifth shield portion 15 (the third shield portion of the present invention) covering the rear B of housing 100 in the third direction X, and a sixth shield portion 16 sandwiched between housing 100 and third shield portion 13 (the thirdA shield portion) and fifth shield portion 15 (the thirdB shield portion).

[0026] The first shield part 11 is perpendicular to the first direction Z, and the second shield part 12 is perpendicular to the second direction Y.

[0027] [1st to 5th shield sections: see Figures 1 and 2] The shield 10 has a first bent portion 21 and a second bent portion 22 formed on both sides of the first shield portion 11 in the second direction Y. In other words, the first shield portion 11 is sandwiched between the first bent portion 21 and the second bent portion 22. The first bent portion 21 and the second bent portion 22 are bent portions that extend in the third direction X.

[0028] 2, the first shield part 11 is adjacent to the second shield part 12 with the first bent part 21 sandwiched therebetween. That is, the second shield part 12 is adjacent to the first shield part 11. The second shield part 12 covers the left side L of the housing 100 in the second direction Y. Two lead parts 43 extending downward D in the first direction Z are formed on the second shield part 12. The lead parts 43 are mounted on the board via through-holes when the communication connector 1 is mounted on the board. During mounting, the lead parts 43 are inserted into the through-holes of the board, soldered, and firmly fixed to the board. The lead parts 43 are electrically connected to the board, thereby being grounded.

[0029] The second shield section 12 is adjacent to the third shield section 13 across a third bent section 23 that further bends the second shield section 12. In other words, the third shield section 13 is continuous with the second shield section 12.

[0030] The third shield part 13, together with the fifth shield part 15, covers the rear side B of the housing 100 in the third direction X. The length of the third shield part 13 in the first direction Z is height L1, and the length of the third shield part 13 in the second direction Y is width L2.

[0031] The third shield part 13 has a lead part 41 that extends downward D in the first direction Z. The length of the lead part 41 in the second direction Y is width L3, which is less than or equal to the width L2 of the third shield part 13. The width L3 of the lead part 41 in the second direction Y, which is the plate width direction of the third shield part 13, is set to a predetermined length within a range less than the width L2.

[0032] The lead portion 41 is a mounting portion that is mounted to the board via a through-hole when the communication connector 1 is mounted to the board. During mounting, the lead portion 41 is inserted into the through-hole of the board, soldered, and firmly fixed to the board. The lead portion 41 is electrically connected to the board, thereby being grounded.

[0033] When a worker mates a mating connector with the communication connector 1, a three-dimensional load may be generated in the mounting portion between the board and the lead portion 41. The lead portion 41 is a mounting portion that is firmly fixed to the board, and is set to a predetermined length in the second direction Y, which is the width direction of the third shield portion 13, so that the communication connector 1 equipped with the shield 10 can be set to a predetermined resistance force against the load in the second direction Y.

[0034] Therefore, the shield 10 can improve resistance to the shield 10 being removed from the board when a load is applied in the second direction Y. Furthermore, the communication connector 1 including the shield 10 can improve resistance to the communication connector 1 being removed from the board when a load is applied in the second direction Y caused by a fitting operation by a worker.

[0035] In order to improve the resistance of the lead portion 43 formed in the second shield portion 12 to loads in the second direction Y, it is necessary to increase the thickness of the second shield portion 12. However, increasing the thickness of the second shield portion 12 requires increasing the thickness of the metal plate of the shield 10 itself, which increases material costs.

[0036] On the other hand, because the lead portion 41 is set to a predetermined length in the second direction Y, which is the plate width direction of the third shield portion 13, there is no need to increase the plate thickness of the metal plate of the shield 10. In other words, the lead portion 41 can be set to a predetermined resistance force against the load of the communication connector 1 in the second direction Y without increasing material costs.

[0037] 1, the first shield section 11 is adjacent to the fourth shield section 14 with the second bent section 22 sandwiched therebetween. That is, the fourth shield section 14 is adjacent to the first shield section 11. The fourth shield part 14 covers the right direction R side of the housing 100 in the second direction Y. The fourth shield part 14 faces the second shield part 12. The fourth shield part 14 has two lead parts 44 formed thereon, extending downward D in the first direction Z. The lead parts 44 are mounting parts that are mounted to the board via through-holes when the communication connector 1 is mounted to the board. During mounting, the lead parts 44 are inserted into the through-holes of the board, soldered, and firmly fixed to the board. The lead parts 44 are electrically connected to the board, thereby being grounded.

[0038] 2, the fourth shield section 14 is adjacent to the fifth shield section 15 across a fourth bent section 24 that further bends the fourth shield section 14. In other words, the fifth shield section 15 is continuous with the fourth shield section 14.

[0039] The fifth shield section 15, together with the third shield section 13, covers the rear side B of the housing 100 in the third direction X. In other words, the third shield section of the present invention, which is composed of the third shield section 13 and the fifth shield section 15, is adjacent to each of the first shield section 11, the second shield section 12, and the fourth shield section 14. The fifth shield section 15 is aligned with and adjacent to the third shield section 13 in the second direction Y. Preferably, the fifth shield section 15 and the third shield section 13 are provided on the same plane. The length of the fifth shield section 15 in the first direction Z is height L4, and the length in the second direction Y is width L5.

[0040] The fifth shield part 15 has a lead part 42 that extends downward D in the first direction Z. The length of the lead part 42 in the second direction Y is width L6, which is less than the width L5 of the fifth shield part 15. The width L6 of the lead part 42 in the second direction Y, which is the plate width direction of the fifth shield part 15, is set to a predetermined length within a range less than the width L5.

[0041] The lead portion 42 is a mounting portion that is mounted to the board via a through-hole when the communication connector 1 is mounted to the board. During mounting, the lead portion 42 is inserted into the through-hole of the board, soldered, and firmly fixed to the board. The lead portion 42 is electrically connected to the board, thereby being grounded.

[0042] When a worker mates a mating connector with the communication connector 1, a three-dimensional load may be generated in the mounting portion between the board and the lead portion 42. The lead portion 42 is a mounting portion that is firmly fixed to the board, and is set to a predetermined length in the second direction Y, which is the width direction of the fifth shield portion 15, so that the communication connector 1 equipped with the shield 10 can be set to a predetermined resistance force against the load in the second direction Y.

[0043] Therefore, the shield 10 can improve resistance to the shield 10 being removed from the board when a load is applied in the second direction Y. Furthermore, the communication connector 1 including the shield 10 can improve resistance to the communication connector 1 being removed from the board when a load is applied in the second direction Y caused by a fitting operation by a worker.

[0044] In order to improve the resistance of the lead portion 44 formed in the fourth shield portion 14 to loads in the second direction Y, it is necessary to increase the thickness of the fourth shield portion 14. However, increasing the thickness of the fourth shield portion 14 requires increasing the thickness of the metal plate of the shield 10 itself, which increases material costs.

[0045] On the other hand, because the lead portion 42 is set to a predetermined length in the second direction Y, which is the width direction of the fifth shield portion 15, there is no need to increase the thickness of the metal plate of the shield 10. In other words, the lead portion 42 can be set to a predetermined resistance force against the load in the second direction Y of the communication connector 1 without increasing material costs.

[0046] The height L1 of the third shield section 13 and the height L4 of the fifth shield section 15 are set to the same length, the width L2 of the third shield section 13 and the width L5 of the fifth shield section 15 are set to the same length, and the width L3 of the lead section 41 and the width L6 of the lead section 42 are set to the same length. The height L1 is greater than the length L2, and the height L4 is greater than the length L5. In this embodiment, the height L1 is twice the length L2. The height L4 is twice the length L5.

[0047] [Relationship between the third shielding portion 13, the fifth shielding portion 15, and the sixth shielding portion 16: see Figures 4 and 5] The first shield part 11 is adjacent to the sixth shield part 16 with the fifth bent part 25 interposed therebetween. That is, the sixth shield part 16 is continuous with the first shield part 11. The sixth shield part 16 is sandwiched between the housing 100 and the third and fifth shield parts 13 and 15. That is, the sixth shield part 16 is aligned with the third and fifth shield parts 13 and 15 in the third direction X. A first dimple part 51 as a first conductive path part and a second dimple part 52 as a second conductive path part are formed on a surface 16B of the sixth shield part 16 on the rear B side in the third direction X.

[0048] 5, the first dimple portion 51 presses against a surface 13F of the third shield portion 13 on the front F side in the third direction X, forming a conductive path that establishes electrical continuity between the sixth shield portion 16 and the third shield portion 13. The second dimple portion 52 presses against a surface 15F of the fifth shield portion 15 on the front F side in the third direction X, forming a conductive path that establishes electrical continuity between the sixth shield portion 16 and the fifth shield portion 15.

[0049] By forming a conductive path between the sixth shield section 16 adjacent to the first shield section 11 and the third shield section 13, a conductive path can be formed through which current flows from the first shield section 11 through the sixth shield section 16 and from the lead section 41 of the third shield section 13 to the substrate. Furthermore, by forming a conductive section between the sixth shield section 16 adjacent to the first shield section 11 and the fifth shield section 15, a conductive path can be formed through which current flows from the first shield section 11 through the sixth shield section 16 and from the lead section 42 of the fifth shield section 15 to the substrate.

[0050] In this way, by forming a conductive path from the first shield part 11 on the upper U side in the first direction Z to the third shield part 13 or the fifth shield part 15 on the rear B side in the third direction X, even in the case of a shield 10 formed by bending a metal plate so that the rear B of the housing 100 is covered by two shield parts, the third shield part 13 and the fifth shield part 15, it is possible to increase the number of conductive paths with short conduction distances for dissipating noise-causing current to parts that do not affect the communication signal, thereby reducing the generation of noise.

[0051] In this embodiment, the first dimple portion 51 and the second dimple portion 52 are formed in the sixth shield portion 16, but this is not limited to this. For example, the first dimple portion 51 may be formed in the third shield portion 13, and the first dimple portion 51 may press against the sixth shield portion 16 to establish electrical continuity between the sixth shield portion 16 and the third shield portion 13. Alternatively, the second dimple portion 52 may be formed in the fifth shield portion 15, and the second dimple portion 52 may press against the sixth shield portion 16 to establish electrical continuity between the sixth shield portion 16 and the fifth shield portion 15.

[0052] In addition, the first shield part 11 may be extended rearward B in the third direction X, and, for example, two dimple parts may be formed on the downward D side of the first shield part 11 in the first direction Z, thereby providing electrical conductivity between one dimple part and the upward U in the first direction Z of the third shield part 13, and between the other dimple part and the upward U in the first direction Z of the fifth shield part 15.

[0053] [Expansion diagram of shield 10 200: Figure 3] As shown in Figure 3, in the developed view 200 of the coil-shaped metal plate of the shield 10, which is formed by folding a metal plate as a metal plate in the developed view, a first shield section 11, a second shield section 12 adjacent to the first shield section 11 on one side of the width direction W with a first folded section 21 between them, and a fourth shield section 14 adjacent to the first shield section 11 on the other side of the width direction W with a second folded section 22 between them are lined up in the width direction W.

[0054] In addition, the sixth shield section 16 is adjacent to the first shield section 11 on the downstream DS side of the dispensing direction P, with the fifth bend section 25 sandwiched between them, the third shield section 13 is adjacent to the second shield section 12 on the downstream DS side of the dispensing direction P, with the third bend section 23 sandwiched between them, and the fifth shield section 15 is adjacent to the fourth shield section 14 on the downstream DS side of the dispensing direction P, with the fourth bend section 24 sandwiched between them, and are lined up in the width direction W.

[0055] In a T-shaped unfolded view, such as that of Patent Document 1, in which the rear B side of the third direction X is covered only by the sixth shield part 16 adjacent to the first shield part 11 and sandwiched between the fifth bend part 25, the length L10 in the dispensing direction P becomes longer and the dispensing pitch P1 becomes longer. In this embodiment, by replacing the sixth shield section 16 covering the rear B side in the third direction X with two shield sections, namely the third shield section 13 adjacent to the second shield section 12 across the third bend section 23, and the fifth shield section 15 adjacent to the fourth shield section 14 across the fourth bend section 24, the length L10 in the dispensing direction P of the unfolded view 200 of the shield 10 can be shortened, and the dispensing pitch P1 can be shortened.

[0056] Therefore, in progressive press working, the dispensing pitch P1 of the coiled metal plate that forms the shield 10 can be shortened, which makes it possible to shorten the process takt time and reduce material costs.

[0057] The height L1 of the third shield section 13 and the height L4 of the fifth shield section 15 are set to the same length, the width L2 of the third shield section 13 and the width L5 of the fifth shield section 15 are set to the same length, and the width L3 of the lead section 41 and the width L6 of the lead section 42 are set to the same length. The height L1 is greater than the length L2, and the height L4 is greater than the length L5. In this embodiment, the height L1 is twice the length L2. The height L4 is twice the length L5.

[0058] When height L1 is greater than length L2, length L10 of development 200 of shield 10 in dispensing direction P is shorter when third shield portion 13 and fifth shield portion 15 are used to cover rear B side of housing 100 in third direction X than when third shield portion 13 and fifth shield portion 15 are not provided and rear B side of housing 100 in third direction X is covered by sixth shield portion 16. The same applies when height L4 is greater than length L5. In such a case, the dispensing pitch P1 can be shortened.

[0059] Here, when height L1 is the same as length L2 or when height L1 is smaller than length L2, the length L10 in the dispensing direction P of the development view 200 of shield 10 will be the same or longer in the case where third shield portion 13 and fifth shield portion 15 are not provided and the rear B side of housing 100 in the third direction X is covered by sixth shield portion 16 and the case where the rear B side of housing 100 in the third direction X is covered by third shield portion 13 and fifth shield portion 15. The same applies when height L4 is the same as length L5 or when height L4 is smaller than length L5. In such a case, the dispensing pitch P1 cannot be shortened.

[0060] [Effects of this embodiment] [Effect 1] In the shield 10 formed by bending a metal plate, the second shield section 12 and the fourth shield section 14 face each other, the third shield section 13 is continuous with the second shield section 12, and the fifth shield section 15 is continuous with the fourth shield section 14. Such a shield 10 can ensure a shielding function for noise prevention, and can also shorten the process takt time and reduce material costs.

[0061] [Effect 2] In shield 10 formed by bending a metal plate, sixth shield portion 16 is adjacent to first shield portion 11 across fifth bend portion 25, and sixth shield portion 16 has a first dimple portion 51 as a first conductive path portion and a second dimple portion 52 as a second conductive path portion formed on surface 16B on the rear B side in third direction X. This increases the number of conductive paths with short conduction distances for dissipating noise-causing current to portions that do not affect communication signals, thereby reducing noise generation.

[0062] [Second embodiment: see Figures 6, 7, and 8] Whereas the shield 10 in the first embodiment is provided with a first dimple portion 51 and a second dimple portion 52 as conductive paths, the present embodiment differs in that tapered portions are provided at the ends of the plates of the third shield portion 13 and the fifth shield portion 15 in the second direction Y, and the tapered portions are pressed against each other to form conductive paths 53. Note that the same elements as in the first embodiment are given the same reference numerals, and their description will be omitted.

[0063] [Third shield part 13 and fifth shield part 15: see Figures 6, 7, and 8] 6, tapered portion 13A as the first tapered portion formed in third shield portion 13 and tapered portion 15A as the second tapered portion formed in fifth shield portion 15 are pressed together to form conductive path portion 53 as the third conductive path portion. The surface of tapered portion 13A is formed on the rear B side in the third direction X, and the surface of tapered portion 15A is formed on the front F side in the third direction X.

[0064] When the metal plate is bent to form the shield 10, it is kept tilted at a predetermined angle with respect to the second direction Y, as shown by the third shield part 13 indicated by the dashed line. In addition, as shown in Fig. 7, the fifth shield part 15 is formed by bending the metal plate at the fourth bend part 24 and then at the second bend part 22, thereby covering the rear B side of the housing 100 in the third direction X.

[0065] When bending at second bending portion 22 is completed, tapered portion 13A is pressed by tapered portion 15A, and third shield portion 13, which had remained in the position shown by the dashed line, elastically deforms to the position shown by the solid line. At this time, third shield portion 13 functions as a leaf spring, and a force acts such that tapered portion 13A pushes back tapered portion 15A.

[0066] The force pressing against the tapered portion 13A by the tapered portion 15A of the fifth shield portion 15 and the force pushing back against the tapered portion 15A by the tapered portion 13A of the third shield portion 13, which functions as a leaf spring, are generated in the conductive path portion 53, thereby stabilizing the electrical connection of the conductive path portion 53.

[0067] When the metal plate is bent at second bending portion 22, tip 15A1 of tapered portion 15A of fifth shield part 15 comes into contact with the surface of tapered portion 13A, and tip 15A1 scrapes the surface of tapered portion 13A. Therefore, a relief portion including sliding surface 13B1, sliding surface 13B2, and gap 13C is formed in tapered portion 13A.

[0068] Sliding surface 13B1 is formed on tapered portion 13A so as to extend obliquely downward D toward the front F in the third direction X. That is, sliding surface 13B1 extends from the outside toward the inside of shield 10, away from third shield part 13. Sliding surface 13B2 is formed so as to extend obliquely upward U toward the front F in the third direction X. That is, sliding surface 13B2 extends from the outside toward the inside of shield 10, away from third shield part 13. A gap 13C is formed between sliding surface 13B1 and sliding surface 13B2.

[0069] Specifically, when the metal plate is bent at the second bend 22, the tip 15A1 of the tapered portion 15A of the fifth shield part 15 enters the gap 13C. In other words, when the last bend of the metal plate is the second bend 22, the gap 13C is formed at the portion where a circle having a radius equal to the length L5 of the fifth shield part 15 in the second direction Y, centered at the second bend 22, intersects with the first tapered portion 13A.

[0070] Thereafter, the bending at second bending portion 22 progresses while tapered portion 15A slides on slide surface 13B1, and tapered portion 15A slides on slide surface 13B2. Finally, the metal plate is bent at second bending portion 22 to a position where tapered portion 15A is pressed against the entire surface of tapered portion 13A.

[0071] By forming a relief portion including sliding surface 13B1, sliding surface 13B2, and gap 13C on the surface of tapered portion 13A, it is possible to suppress the generation of metal chips caused by contact and strong rubbing between metal plates that occurs when bending the metal plates.

[0072] In addition to the above, the configurations given in the above embodiments can be selected or changed as appropriate to other configurations without departing from the spirit of the present invention. [Explanation of symbols]
