Next, an example of the present disclosure is described in accordance with the drawings. In the following description, terms (e.g., terms including "upper", "lower", "left", "right") indicating a specified direction or position are used as needed, but the use of the terms is for ease of understanding the present disclosure with reference to the drawings, and the technical scope of the present disclosure is not limited by the meaning of the terms. In addition, the following description is merely exemplary in nature and is not intended to limit the present disclosure, its application, or uses. The drawings are schematic, and the ratio of the dimensions and the like do not necessarily match the actual situation.
As shown in fig. 1, an inspection socket 1 of one embodiment of the present disclosure has a conductive first housing 10, and a conductive signal terminal 20 housed in the first housing 10. As shown in fig. 2, the inspection socket 1 includes an insulating portion 40 that insulates the signal terminal 20 from the first housing 10 in the first housing 10. In this embodiment, the inspection socket 1 has a plurality of signal terminals 20 as an example. The signal terminals 20 are plate-shaped by electroforming, and are arranged so that the plate thickness directions coincide with each other. In addition, in this embodiment, the first housing 10 is used as the Ground (GND).
As shown in fig. 1, the first housing 10 has a substantially rectangular parallelepiped shape, and as shown in fig. 2, has a plurality of first storage portions 11 therein. In each first housing portion 11, one signal terminal 20 is housed by an insulating portion 40 in an electrically independent state with respect to the first case 10, and a first contact portion 23 described later is exposed to the outside through an opening portion 13.
As shown in fig. 1 and 2, the first case 10 has a plurality of substantially circular openings 13 at substantially the center of both surfaces in the thickness direction. Each first housing portion 11 extends in the thickness direction of the first casing 10 (for example, the up-down direction in fig. 2, hereinafter referred to as a first direction X), and includes first portions 111 disposed at both ends in the first direction X, and second portions 112 disposed between the first portions 111. Each first portion 111 is connected to the opening 13. A gap is formed in the second direction Y between the inner surface of each first housing portion 11 constituting the first portion 111 and the signal terminal 20. The second direction Y is a direction intersecting the first direction X and the board thickness direction of the signal terminal 20. The second portions 112 are larger in size in the second direction Y intersecting the first direction X than the first portions 111, and accommodate the insulating portions 40. Each signal terminal 20 is held in the first housing portion 11 via the insulating portion 40.
Each of the signal terminals 20 is connected to a signal line provided in an inspection object or an inspection apparatus, not shown, for example, and can transmit a high-frequency signal. As shown in fig. 3, in this embodiment, each signal terminal 20 has: an elastic portion 21 that expands and contracts in the first direction X, and contact portions 22 that are provided at both ends of the elastic portion 21 in the first direction X, respectively. The elastic portion 21 and the contact portion 22 are integrally configured and arranged in series along the first direction X.
The elastic portion 21 has a curved shape as an example. Specifically, the elastic portion 21 includes: a plurality of linear portions 211 extending in the second direction Y and arranged at intervals in the first direction X, and a curved portion 212 connected to one end of each of the linear portions 211 adjacent to each of both ends.
Each contact portion 22 has a substantially rectangular plate-like main body portion 221 extending in the first direction X. An intermediate portion 222 having a width (in other words, a dimension in the second direction Y) larger than that of the main body portion 221 is provided at one end portion of each contact portion 22 in the first direction X, which is close to the elastic portion 21. A pair of shoulders 223 extending from the main body 221 in the second direction Y in mutually opposite directions are provided at the boundary portion between the main body 221 and the intermediate portion 222. Further, first contact portions 23 are provided at one end of each contact portion 22 in the first direction X away from the elastic portion 21 (in other words, at both ends of the signal terminal 20 in the first direction X). In this embodiment, each of the first contact portions 23 has a curved shape recessed toward the elastic portion 21 in the first direction X, and is configured to be contactable with a terminal of an inspection apparatus or an inspection object, not shown.
As shown in fig. 4, the insulating portion 40 is constituted by an insulating second case 41 as an example. As shown in fig. 2, the second housing 41 has a substantially cylindrical shape, and has inside thereof: the third housing 411 is capable of housing and holding the signal terminal 20, and the openings 412 and 413 provided at both ends in the first direction X and connected to the third housing 411, respectively. One of the openings 412 has a size capable of inserting the elastic portion 21 of the signal terminal 20. The other opening 413 is smaller than the one opening 412 and has a size capable of inserting the contact portion 22 of the signal terminal 20. The third housing 411 houses the elastic portion 21 of the signal terminal 20 and the intermediate portion 222 of each contact portion 22, and the shoulder 223 of one contact portion 22 contacts the inner surface of the second housing 41 constituting the third housing 411. Further, a part of the main body 221 of each contact 22 of the signal terminal 20 is exposed to the outside of the second housing 41 through the openings 412 and 413. In other words, the second housing 41 houses the signal terminals 20 therein in a state where the first contact portions 23 are exposed to the outside through the opening portions 13.
According to the inspection socket 1, the following effects can be exhibited.
The inspection socket 1 has: the signal terminal 20 is formed in a plate shape, the first housing 10 having a conductive portion 11 for accommodating the signal terminal 20 therein, and the insulating portion 40 for insulating the signal terminal 20 from the first housing 10. With the above configuration, the distance between the signal terminal 20 and the first housing 10 used as the ground can be ensured to be constant, so impedance integration can be easily performed. In addition, since the signal terminal 20 is housed inside the conductive first housing 10, noise can be suppressed by the shielding effect. As a result, the inspection socket 1 capable of reducing the transmission loss of the signal in the high frequency region can be realized.
The insulating portion 40 is constituted by an insulating second housing 41 that houses the signal terminal 20 therein in a state where the first contact portion 23 is exposed to the outside. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of signals in the high frequency region can be easily realized.
The inspection socket 1 may be configured as follows.
The inspection socket 1 is not limited to the case of having a plurality of signal terminals 20, as long as it has at least one signal terminal 20.
As shown in fig. 5 to 10, the inspection socket 1 may further have at least one ground terminal 30.
Fig. 5 to 10 show an inspection unit 2 having a plurality of inspection sockets 1. The inspection unit 2 has: the inspection socket 1, a base housing 3 that houses the inspection socket 1, and a swinging member 4 that is disposed inside the base housing 3 and is supported by the base housing 3 in a swingable state with respect to the inspection socket 1.
As shown in fig. 6, each inspection socket 1 includes: the first housing 10, and four signal terminals 20 and two ground terminals 30 housed in the first housing 10, respectively. In each inspection socket 1, the signal terminals 20 and the ground terminals 30 are disposed so as to face each other on the surface in the plate thickness direction and so as to be spaced apart from each other in the plate thickness direction, and four signal terminals 20 are located between two ground terminals 30.
As shown in fig. 6, the first casing 10 has a substantially rectangular parallelepiped box shape, and as shown in fig. 8, openings 13 having different sizes in the second direction Y are provided at both ends in the first direction X. One opening 13 (for example, the lower opening 13 in fig. 8) has a size that allows the elastic portions 21 and 31 of the signal terminal 20 and the ground terminal 30 to be inserted. The other opening 13 (for example, the upper opening 13 in fig. 8) has a size smaller than that of the one opening 13 and into which the contact portions 22 and 32 of the signal terminal 20 and the ground terminal 30 can be inserted. Each of the first housing portions 11 houses one signal terminal 20, and a portion 421 of the pair of insulating members 42, which is attached to the linear portion 211 of the elastic portion 21 located at one end in the first direction X, is in contact with the inner surface of the second housing 41 constituting the third housing portion 411. Although not shown, one ground terminal 30 is housed in each second housing 12, and a linear portion of the elastic portion 31 located at one end in the first direction X contacts the inner surface of the second housing 41. As shown in fig. 8, the first housing portion 11 and the second housing portion 12 have substantially the same dimensions in the second direction Y (only the first housing portion 11 is shown in fig. 8).
As shown in fig. 5, the swinging member 4 has insulation properties, and has a connection portion 5 that is exposed to the outside of the first housing 10 and is connectable to a contact object (for example, an inspection object or an inspection device). The connection portion 5 is provided with a through hole 6 penetrating the connection portion 5 in the swinging direction (for example, the first direction X). As shown in fig. 7, the first contact portion 23 of one of the signal terminals 20 and the second contact portion 33 of one of the ground terminals 30 are accommodated in the through hole 6. As shown in fig. 7, the swinging member 4 is biased from the inside of the first housing 10 to the outside in the first direction X by a plurality of coil springs 8 arranged in the inside of the first housing 10.
As shown in fig. 9, the elastic portion 21 of each signal terminal 20 is constituted by a plurality of elastic pieces 24 and 25 arranged with a gap 26 therebetween, and the intermediate portion 222 is not provided in each contact portion 22. In addition, the first contact portions 23 of the signal terminals 20 are different in shape.
As shown in fig. 10, each of the ground terminals 30 is formed in a plate shape by electroforming, as in the case of the signal terminals 20, and includes: the elastic portion 31 and the contact portion 32, which are composed of the plurality of elastic pieces 34 and 35 disposed with the gap 36 therebetween, have substantially the same shape as the signal terminal 20 except for the second contact portion 33.
In the inspection unit 2 of fig. 5 to 10, the signal terminal 20 and the ground terminal 30 each have a plate shape and are accommodated in the first accommodation portion 11 and the second accommodation portion 12 so that the plate thickness directions coincide with each other. With the above configuration, the inspection socket 1 can be realized which reliably reduces the transmission loss of signals in the high frequency region.
The signal terminal 20 and the ground terminal 30 are not limited to a plate shape, and may have any other shape. The signal terminal 20 and the ground terminal 30 are not limited to the case having the elastic portions 21 and 31 and the contact portions 22 and 32, and may have any other configuration having contact portions at both ends in the first direction X.
In the inspection unit 2 shown in fig. 5 to 10, the insulating portion 40 is constituted by a pair of insulating members 42 attached to both sides of the signal terminal 20 in the board thickness direction thereof. That is, the insulating portion 40 is not limited to the case constituted by the second housing 41.
As shown in fig. 8 and 9, the insulating members 42 are attached to both surfaces of the signal terminals 20 in the plate thickness direction. Each insulating member 42 has a thin film shape and has a shape along the contact portion 22 excluding the elastic portion 21 and the first contact portion 23. The insulating members 42 are configured such that the outer shape line of each of the insulating members is located at a position further outward than the outer shape line of each of the signal terminals 20 when viewed in the plate thickness direction of each of the signal terminals 20. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of signals in the high frequency region can be more easily realized. The insulating member 42 is not attached to the ground terminal 30.
As shown in fig. 11 to 13, the insulating portion 40 may be constituted by an insulating layer 43 provided over the entire inner surface of the first housing 10 constituting the first housing portion 11, for example. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of signals in the high frequency region can be more easily realized.
In the inspection socket 1 shown in fig. 11 to 13, the first housing 10 has openings 13 having different sizes in the second direction Y at both ends in the first direction X. One opening 13 (for example, the upper opening 13 in fig. 12 and 13) has a size that allows the elastic portion 21 of the signal terminal 20 to be inserted. The other opening 13 (for example, the opening 13 on the lower side in fig. 12 and 13) has a size smaller than that of the one opening 13 and into which the contact portion 22 of the signal terminal 20 can be inserted. In each first housing portion 11, one signal terminal 20 is housed in a state in which the shoulder 223 of one contact portion 22 is in contact with the insulating layer 43 and the shoulder 223 of the other contact portion 22 is located outside the first housing 10.
The insulating layer 43 may be provided only in a part of the first housing portion 11 instead of the entire first housing portion.
As shown in fig. 14 to 16, the insulating portion 40 may be constituted by a pair of third housings 44 covering portions other than the first contact portions 23 at both ends of the signal terminal 20 in the first direction X, for example.
In the inspection socket 1 shown in fig. 14 to 16, each third housing 44 includes: a first cylindrical portion 441, and a second cylindrical portion 442 connected to one end of the first cylindrical portion 441 in the first direction X. The first cylindrical portion 441 covers a portion of the main body portion 221 of each contact portion 22 of each signal terminal 20. The second cylindrical portion 442 covers a part or all of the intermediate portion 222 of each contact portion 22 of each signal terminal 20, and has a first direction X smaller in size than the first cylindrical portion 441 and a radial dimension with respect to the first direction X larger than the first cylindrical portion 441. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of signals in the high frequency region can be more easily realized.
