[0011] 1 and 2, the connector 100 according to the embodiment is a connector mounted on a circuit board BS, a so-called PCB (Printed Circuit Board) connector. The connector 100 has a shielding function for suppressing leakage of electromagnetic waves caused by signals transmitted via inner terminals 50 within the connector 100 and intrusion of electromagnetic waves from the outside.

[0012] As shown in FIGS. 2 and 3, the connector 100 includes an outer terminal 10, an outer housing 20, a shield shell 30, an inner housing (40), and an inner terminal (50).

[0013] The outer terminal 10 is a metal member and has a tubular portion 11 and a locking piece 12 that protrudes radially outward from one end 11bb of the tubular portion 11. As shown in Fig. 4, the tubular portion 11 of the embodiment is formed in a cylindrical shape that extends in one direction.

[0014] In the following description, the extension direction of the tubular portion 11 is referred to as the "first direction X." A direction intersecting the first direction X is referred to as the "second direction" Y, and a direction intersecting both the first direction X and the second direction Y is referred to as the "third direction Z." In the embodiment, the first direction X, the second direction Y, and the third direction Z are mutually orthogonal. In the embodiment, the first direction X corresponds to the direction along the mating direction of the connector 100 and a mating connector (not shown), the second direction Y corresponds to the width direction of the connector 100, and the third direction Z corresponds to the direction along the mounting direction of the connector 100 to a circuit board BS (described later). In the third direction Z, the side of the connector 100 facing the circuit board BS (described later) is referred to as the "lower side," and the side opposite the circuit board BS side is referred to as the "upper side."

[0015] The cylindrical portion 11 is composed of a large diameter portion 11a, a small diameter portion 11b having a diameter smaller than that of the large diameter portion 11a, and a connecting portion 11c located between the large diameter portion 11a and the small diameter portion 11b and having a diameter that gradually decreases from the large diameter portion 11a toward the small diameter portion 11b. The large diameter portion 11a, the connecting portion 11c, and the small diameter portion 11b are arranged side by side in this order along the first direction X. The locking piece 12 is formed at an end 11bb of the small diameter portion 11b on the opposite side from the connecting portion 11c.

[0016] The outer housing 20 is a member made of insulating resin. As shown in FIG. 5 , the outer housing 20 of this embodiment is formed in a rectangular tube shape extending along the first direction X. A first opposing wall portion 20a is provided at one end of the rectangular tube-shaped outer housing 20. The first opposing wall portion 20a is a wall portion that faces the shield shell 30 in the first direction X. A first through hole 21 that connects the inside and outside of the outer housing 20 is formed in the first opposing wall portion 20a. The first through hole 21 is formed in a shape corresponding to the small diameter portion 11b of the outer terminal 10, and in this embodiment, is formed as a circular through hole.

[0017] The shield shell 30 is made of a conductive material such as aluminum. The shield shell 30 is one of the components that provides the shielding function of the connector 100. As shown in FIGS. 2 and 3 , the shield shell 30 is U-shaped and opens downward. The shield shell 30 includes a side wall 30a extending along the first direction X and a second opposing wall 30b provided at one end of the side wall 30a in the extending direction. The second opposing wall 30b faces the first opposing wall 20a of the outer housing 20 in the first direction X. As shown in FIGS. 2 and 6 , the second opposing wall 30b is formed with a second through hole 31 that connects the inside of the shield shell 30 surrounded by the side wall 30a with the outside of the shield shell 30. Like the first through hole 21, the second through hole 31 is formed in a shape corresponding to the small-diameter portion 11b of the outer terminal 10. In this embodiment, the second through hole 31 is formed as a circular through hole.

[0018] 2, the outer housing 20 and the shield shell 30 are assembled with the outer surfaces of the first opposing wall portion 20a and the second opposing wall portion 30b in contact with each other. When the outer housing 20 and the shield shell 30 are assembled, the second through hole 31 of the shield shell 30 communicates with the first through hole 21 of the outer housing 20.

[0019] In the embodiment, the first opposing wall portion 20a of the outer housing 20 and the second opposing wall portion 30b of the shield shell 30 are formed in shapes that allow them to fit together. As shown in FIG. 5, the first opposing wall portion 20a of the outer housing 20 in the embodiment has a fitting recess 20aa that is recessed toward the inside of the outer housing 20. The fitting recess 20aa is formed on the periphery of the first through hole 21. In the embodiment, the fitting recess 20aa is formed as a ring-shaped recess surrounding the first through hole 21. Also, as shown in FIG. 6, the second opposing wall portion 30b of the shield shell 30 in the embodiment has a fitting protrusion 30bb that has a shape corresponding to the fitting recess 20aa of the outer housing 20. The fitting protrusion 30bb is a portion that protrudes toward the first opposing wall portion 20a of the outer housing 20. In the embodiment, the fitting protrusion 30bb is formed as a ring-shaped protrusion surrounding the second through hole 31.

[0020] 2 , with the cylindrical portion 11 (small diameter portion 11b) of the outer terminal 10 inserted into the first through hole 21 and the second through hole 31, the locking piece 12 is locked to the edge of the second through hole 31 on the side opposite to the outer housing 20 side in the shield shell 30. In the embodiment, the inner diameters of the first through hole 21 and the second through hole are substantially the same as the outer shape of the small diameter portion 11b of the cylindrical portion 11, and with the small diameter portion 11b of the cylindrical portion 11 inserted into the first through hole 21 and the second through hole 31, the locking piece 12 is locked to the edge of the second through hole 31 on the side opposite to the outer housing 20 side in the shield shell 30, and the connecting portion 11c abuts against the edge of the first through hole 21 on the side opposite to the shield shell 30 side in the outer housing 20, thereby assembling the outer terminal 10 to the outer housing 20 and the shield shell 30.

[0021] 4, a pair of slits ST extending from one end 11bb of the cylindrical portion 11 toward the other end 11aa thereof is formed in the cylindrical portion 11 of the outer terminal 10 at positions sandwiching the base ends of the locking pieces 12 in the circumferential direction of the cylindrical portion 11. In the embodiment, three locking pieces 12 are formed in the one end 11bb (i.e., the end on the small diameter portion 11b side) of the cylindrical portion 11, and a pair of slits ST is formed in each of the three locking pieces 12 so as to sandwich the base end of each locking piece 12 in the circumferential direction of the cylindrical portion 11. Of the three locking pieces 12, two locking pieces 12 protrude radially outward from both ends of the cylindrical portion 11 in the second direction Y, and the remaining locking piece 12 protrudes radially outward from one end (lower end) of both ends in the third direction Z.

[0022] 2, in the insertion direction (first direction X) of the outer terminal 10, the length L1 of each slit ST is set to be equal to or less than the length L2 of the second through hole 31 of the shield shell 30. When the outer terminal 10 is assembled to the outer housing 20 and the shield shell 30, the end portion on the other end 11aa side (i.e., the end side on the large diameter portion 11a side) of each slit ST faces the inner circumferential surface of the second through hole 31 of the shield shell 30. In other words, when the outer terminal 10 is assembled to the outer housing 20 and the shield shell 30, the slit ST is entirely covered by the shield shell 30.

[0023] Inner housing 40 is an insulating resin member. As shown in FIGS. 2 and 3 , inner housing 40 has a hanging portion 41 and a cylindrical main body portion 42 that protrudes from hanging portion 41 in first direction X. Hanging portion 41 hangs downward from the portion where main body portion 42 protrudes. When viewed from second direction Y, inner housing 40 is formed in an L-shape. A slit-shaped opening is formed in the wall of hanging portion 41 on the side opposite to main body portion 42, and this opening communicates with the space inside cylindrical main body portion 42. The slit-shaped opening of hanging portion 41 and the space inside main body portion 42 form a housing space that houses inner terminal 50.

[0024] The inner terminal 50 is a metal member. The inner terminal 50 includes a rod-shaped first portion 50a extending in the first direction X and a rod-shaped second portion 50b hanging down from an end of the first portion 50a and extending in the third direction Z. The first portion 50a is inserted inside the main body 42, and the second portion 50b is inserted inside a slit-shaped opening in the hanging portion 41. The inner terminal 50 is held in the inner housing 40 with the tip of the first portion 50a protruding from the tip of the main body 42 and the tip of the second portion 50b protruding from the lower end of the hanging portion 41.

[0025] The mating connector is inserted into the opening of the rectangular cylindrical outer housing 20 on the side opposite to the first opposing wall portion 20a, and is mated with the outer housing 20. The tip of the first portion 50a (the end opposite to the second portion 50b) is narrower in diameter than the other portions of the first portion 50a, and is configured to connect with the female terminals of the mating connector when the outer housing 20 of the connector 100 is mated with the mating connector. The tip (lower end) of the second portion 50b is narrower in diameter than the other portions of the second portion 50b, and is configured to be inserted into a through-hole TH1 of the circuit board BS when the connector 100 is mounted on the circuit board BS.

[0026] The inner housing 40, holding the inner terminal 50, is accommodated in the shield shell 30 from the side opposite the outer housing 20 side. The main body 42 of the inner housing 40 is inserted into the outer terminal 10 with the hanging portion 41 sandwiching the locking piece 12 between the shield shell 30 and the shield shell 30. With the locking piece 12 sandwiched between the hanging portion 41 and the shield shell 30, rotation (circumferential rotation) of the outer terminal 10 relative to the outer housing 20 and the shield shell 30 is suppressed.

[0027] The connector 100 is mounted on the circuit board BS by inserting the second portion 50b of the inner terminal 50 into a through hole TH1 formed in the circuit board BS. A conductive film, such as copper plating, is provided on the inner surface of the through hole TH1, and the conductive film is connected to the conductor pattern of the circuit board BS. The inner terminal 50 is electrically connected to the conductor pattern of the circuit board BS via the conductive film of the through hole TH1. In addition, in the connector 100, legs 33 that protrude downward are formed at each of the four corners of the lower end of the shield shell 30. The legs 33 are inserted into and soldered to through holes TH2 (see FIG. 14) that correspond to grounding parts formed on the circuit board BS. With this configuration, the connector 100 is fixed to the circuit board 3.

[0028] In the embodiment, a high-frequency signal transmitted by the inner terminal 50 of the connector 100 is transmitted to the conductive pattern of the circuit board BS. Furthermore, the shield shell 30 and the outer terminal 10 block (collect) electromagnetic waves, and thus a minute current generated in the shield shell 30 and the outer terminal 10 is grounded to the earth part (through hole TH2) of the circuit board BS.

[0029] Next, a method for manufacturing the connector 100 according to the embodiment will be described with reference to Figures 7 to 14. In the following description, explanations will be given based on the flowchart in Figure 7, with reference to other figures as appropriate. The method for manufacturing the connector 100 described below will be described as being performed manually by an operator using various devices, equipment, jigs, etc., but is not limited to this and may also be performed automatically by various manufacturing devices.

[0030] First, as shown in FIG. 7 , in the outer terminal insertion step S1, an operator inserts the outer terminal 10 from the locking piece 12 side into the first through hole 21 of the outer housing 20, and then inserts the outer terminal 10 from the outside of the shield shell 30 into the second through hole 31 of the shield shell. As shown in FIGS. 8 and 9 , the locking piece 12 of the outer terminal 10 is pre-bent so as to protrude radially outward from one end 11bb of the tubular portion 11. As shown in FIG. 2 , the locking piece 12 of the embodiment is pre-bent so that an intermediate portion between the connection end with the tubular portion 11 and the free end opposite the connection end protrudes toward the side opposite the large diameter portion 11a. That is, the locking piece 12 of the embodiment is pre-bent so that the intermediate portion is curved convexly toward the side opposite the large diameter portion 11a. This shape of the locking piece 12 makes it easier for the outer terminal 10 to be guided into the first through hole 21. In addition, such a shape of the locking piece 12 makes it easier for an operator to find the entrance of the first through hole 21 of the outer housing 20. In addition, as shown in Fig. 9, the outer terminal 10 of the embodiment has a slit ST formed therein, and therefore the portion of the tubular portion 11 connected to the locking piece 12 elastically deforms inward of the tubular portion 11, thereby reducing the insertion force required to insert the outer terminal 10 into the first through hole 21 and the second through hole 31.

[0031] As shown in Figure 10, when the locking piece 12 of the outer terminal 10 passes through the second through hole 31, the part of the tubular portion 11 that is connected to the locking piece 12 elastically recovers, and the locking piece 12 is locked to the edge of the second through hole 31 on the opposite side of the outer housing 20 in the shield shell 30.

[0032] At this time, in the insertion direction (first direction X) of the outer terminal 10, the length L1 (see FIG. 2) of the slit ST of the tubular portion 11 is set to be equal to or less than the length L2 (see FIG. 2) of the second through hole 31 of the shield shell 30. Therefore, in a state in which the outer terminal 10 is assembled to the outer housing 20 and the shield shell 30, the end portion on the other end 11aa side of the slit ST (i.e., the end side on the large diameter portion 11a side) faces the inner circumferential surface of the second through hole 31 of the shield shell 30. In other words, when the outer terminal 10 is assembled to the outer housing 20 and the shield shell 30, the entire slit ST is covered by the shield shell 30.

[0033] Next, in an inner terminal insertion step S2, the worker inserts the inner terminal 50 into the inner housing 40. As shown in FIG. 11 , the worker inserts the inner terminal 50 into the inner housing 40 through a slit-shaped opening formed on the side of the hanging portion 41 opposite to the main body portion 42. In the inner terminal insertion step S2 of the embodiment, the first portion 50a of the inner terminal 50 is press-fitted into the main body portion 42 of the inner housing 40. This press-fitting continues until the second portion 50b of the inner terminal 50 abuts against the hanging portion 41 in the first direction X. As a result of this press-fitting, the tip of the first portion 50a protrudes from the tip of the main body portion 42.

[0034] 12 and 13 , in an inner housing accommodating step S3, the worker inserts the main body portion 42 of the inner housing 40 into the tubular portion 11 from the locking piece 12 side of the outer terminal 10, and sandwiches the locking piece 12 between the hanging portion 41 and the edge of the second through hole 31. By sandwiching the pre-bent locking piece 12 between the hanging portion 41 and the edge of the second through hole 31, the pre-bent locking piece 12 is bent so as to follow the edge of the second through hole 31. By bending the pre-bent locking piece 12 so as to follow the edge of the second through hole 31, the outer terminal 10 is more firmly locked to the shield shell 30. In this embodiment, the main body portion 42 of the inner housing 40 is press-fitted into the small diameter portion 11b of the outer terminal 10 from the locking piece 12 side. This press-fitting continues until the inner housing 40 sandwiches the locking piece 12 and bends it along the edge of the second through hole 31. With this configuration, the worker can lock the outer terminal 10 to the shield shell 30 without using a dedicated jig for bending the locking piece 12.

[0035] The connector 100 according to the embodiment can be manufactured by the above-described manufacturing method. The connector 100 is mounted on, for example, a circuit board BS. As shown in FIG. 14 , an operator inserts the tip of the second portion 50b of the inner terminal 50 into the through-hole TH1 of the circuit board BS, and inserts the leg portion 33 of the shield shell 30 into the through-hole TH2 of the circuit board BS. This operation electrically connects the connector 100 to the circuit board BS. The operator then fixes the connector 100 to the circuit board BS by soldering the connection points between the connector 100 and the circuit board BS.

[0036] As described above, the connector 100 according to the embodiment includes the outer housing 20 having the first through hole 21, the shield shell 30 having the second through hole 31 and arranged so that the second through hole 31 communicates with the first through hole 21, the outer terminal 10 having the tubular portion 11 and the locking piece 12 protruding radially outward from one end 11bb of the tubular portion 11, and the locking piece 12 is locked to the edge of the second through hole 31 on the side of the shield shell 30 opposite to the outer housing 20 side when the tubular portion 11 is inserted into the first through hole 21 and the second through hole 31, and the outer terminal 10 having the hanging portion 41 and the locking piece 12 protruding from the hanging portion 41. The connector is provided with an inner housing 40 having a cylindrical main body 42, with the main body 42 inserted into the outer terminal 10 and the hanging portion 41 sandwiching the locking piece 12 between it and the shield shell 30, and an inner terminal 50 held in the inner housing 40 with a portion protruding from the tip of the main body 42, and the cylindrical portion 11 is formed with a pair of slits ST extending from one end 11bb of the cylindrical portion 11 toward the other end 11aa at a position that sandwiches the base end of the locking piece 12 in the circumferential direction of the cylindrical portion 11, and the ends of the pair of slits ST on the other end 11aa side face the inner surface of the second through hole 31.

[0037] In the connector 100 according to the embodiment, by forming a pair of slits ST in the tubular portion 11, the portion of the tubular portion 11 connected to the locking piece 12 can be made springy. This configuration reduces the insertion force required to insert the outer terminal 10 into the first through hole 21 and the second through hole. Furthermore, the pair of slits ST of the outer terminal 10 inserted into the shield shell 30 are blocked by the inner wall surface of the second through hole 31 of the shield shell 30. This configuration suppresses noise leakage from the connector 100 to the outside and electromagnetic waves from entering from the outside, thereby improving shielding performance. Furthermore, when inserting the outer terminal 10 into the outer housing 20, the locking piece 12 can also pick up the entrance of the first through hole 21 of the outer housing 20 and can also align the outer terminal 10 with the first through hole 21. Therefore, the connector 100 according to the embodiment can improve shielding performance while improving workability during manufacturing.

[0038] [Reference Example of Embodiment] Next, a connector according to a reference example of an embodiment will be described with reference to Fig. 15. The connector according to the reference example differs from the above embodiment in that the length L3 of the slit ST in the first direction X is set to be longer than the length L2 (see Fig. 2) of the second through hole 31 of the shield shell 30 in the first direction X. The other configurations are the same as those of the above embodiment. Furthermore, the connector according to the reference example of an embodiment can be manufactured by a manufacturing method similar to that of the connector according to the above embodiment.

[0039] By increasing the length L3 of the slit ST in the tubular portion 11, the portion of the tubular portion 11 connected to the locking piece 12 can be elastically deformed more greatly toward the inside of the tubular portion 11, and the insertion force required when inserting the outer terminal 10 into the first through hole 21 and the second through hole can be reduced more significantly. However, since the slit ST extends into the first through hole 21 of the outer housing 20, the shielding performance is reduced compared to the connector 100 of the above-mentioned embodiment.

[0040] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
