Detailed Description
An example of the present disclosure is explained below with reference to the drawings. In the following description, terms (for example, terms including "upper", "lower", "left", "right") indicating a designated direction or position are used as necessary, but the terms are used for easy understanding of the present disclosure with reference to the drawings, and the technical scope of the present disclosure is not limited by the meanings of the terms. The following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications, or uses. In addition, the drawings are schematic, and ratios of the respective dimensions and the like do not necessarily coincide with actual cases.
As shown in fig. 1, an inspection socket 1 according to an 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 for insulating the signal terminals 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 each formed by electroforming in a plate shape, and are arranged so as to be aligned with each other in the plate thickness direction. In addition, in this embodiment, the first housing 10 is used as the Ground (GND).
As shown in fig. 1, the first casing 10 has a substantially rectangular parallelepiped shape, and as shown in fig. 2, has a plurality of first housing portions 11 therein. In each first housing portion 11, one signal terminal 20 is housed in an electrically independent state from the first housing 10 by an insulating portion 40, 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 casing 10 has a plurality of substantially circular openings 13 at substantially central portions of both surfaces in the thickness direction. Each first housing section 11 extends in the thickness direction of the first housing 10 (for example, the vertical direction in fig. 2, hereinafter referred to as the first direction X), and has 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 thickness direction of the signal terminals 20. The second portion 112 has a dimension in the second direction Y intersecting the first direction X larger than that of each first portion 111, and houses the insulating portion 40. Each signal terminal 20 is held in the first housing portion 11 via an insulating portion 40.
Each signal terminal 20 is connected to a signal line provided in an inspection object or an inspection apparatus, not shown, for example, and is configured to transmit a high-frequency signal. As shown in fig. 3, in this embodiment, each signal terminal 20 includes: an elastic portion 21 that expands and contracts in the first direction X, and contact portions 22 provided at both ends of the elastic portion 21 in the first direction X. The elastic portion 21 and the contact portion 22 are integrally 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-shaped body portion 221 extending in the first direction X. An intermediate portion 222 having a larger width (in other words, a dimension in the second direction Y) than 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 body portion 221 in the second direction Y in mutually opposite directions are provided at the boundary portion between the body portion 221 and the intermediate portion 222. Further, the first contact portions 23 are provided at one end portions of the contact portions 22 in the first direction X, which end portions are distant from the elastic portion 21 (in other words, both end portions 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 in contact 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 in its interior: a third housing portion 411 capable of housing and holding the signal terminal 20, and openings 412 and 413 provided at both ends in the first direction X and connected to the third housing portion 411, respectively. One opening 412 has a size into which the elastic portion 21 of the signal terminal 20 can be inserted. The other opening 413 has a size smaller than the one opening 412 and into which the contact portion 22 of the signal terminal 20 can be inserted. The elastic portion 21 of the signal terminal 20 and the intermediate portion 222 of each contact portion 22 are housed in the third housing portion 411, and the shoulder portion 223 of one contact portion 22 is in contact with the inner surface of the second case 41 constituting the third housing portion 411. Further, a part of the body portion 221 of each contact portion 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 accommodates the signal terminal 20 therein in a state where the first contact portion 23 is exposed to the outside through the opening 13.
The inspection socket 1 can exhibit the following effects.
The inspection socket 1 has: the signal terminal includes a plate-shaped signal terminal 20, a conductive first housing 10 having a first housing portion 11 for housing the signal terminal 20 therein, and an 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 a ground can be kept constant, and therefore impedance matching can be easily performed. In addition, since the signal terminals 20 are 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 range can be realized.
The insulating portion 40 is constituted by an insulating second housing 41 which 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 the signal 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 includes a pair of inspection sockets 1, a base housing 3 that houses the pair of inspection sockets 1, and a swinging member 4 that is disposed inside the base housing 3 and is supported by the base housing 3 in a state of being swingable with respect to the pair of inspection sockets 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 arranged so that their surfaces in the plate thickness direction face each other with a space therebetween in the plate thickness direction, and the four signal terminals 20 are located between the two ground terminals 30.
As shown in fig. 6, the first casing 10 has a substantially rectangular box shape, and as shown in fig. 8, 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 opening 13 on the lower side in fig. 8) has a size into which the elastic portions 21 and 31 of the signal terminal 20 and the ground terminal 30 can be inserted. The other opening 13 (for example, the upper opening 13 in fig. 8) has a size smaller than 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. One signal terminal 20 is housed in each first housing portion 11, and a portion 421 of the pair of insulating members 42 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 portion 12, and the linear portion of the elastic portion 31 located at one end in the first direction X is in contact with 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 dimension in the second direction Y (only the first housing portion 11 is shown in fig. 8).
As shown in fig. 5, the swing member 4 has an insulating property, and has a connection portion 5 exposed to the outside of the first housing 10 and connectable to a contact object (e.g., an inspection object or an inspection device). The connecting portion 5 is provided with a through hole 6 penetrating the connecting portion 5 in the swinging direction (for example, the first direction X). As shown in fig. 7, the through-hole 6 accommodates one first contact portion 23 of each signal terminal 20 and one second contact portion 33 of each ground terminal 30. As shown in fig. 7, the swing member 4 is biased in the first direction X from the inside to the outside of the first casing 10 by a plurality of coil springs 8 disposed inside the first casing 10.
As shown in fig. 9, the elastic portion 21 of each signal terminal 20 is composed of 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. The first contact portions 23 of the signal terminals 20 are different in shape.
As shown in fig. 10, each ground terminal 30 is, for example, a plate-like member formed by electroforming in the same manner as the signal terminal 20, and includes: the elastic portion 31 and the contact portion 32, which are formed of the plurality of elastic pieces 34 and 35 arranged 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 terminals 20 and the ground terminals 30 each have a plate shape, and are housed in the first housing portion 11 and the second housing portion 12 so that the plate thickness directions thereof coincide with each other. With the above configuration, the inspection socket 1 capable of reliably reducing the transmission loss of the signal in the high frequency region can be realized.
The signal terminals 20 and the ground terminals 30 are not limited to plate-like shapes, and may have any other shapes. The signal terminals 20 and the ground terminals 30 are not limited to 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 formed of a pair of insulating members 42 attached to both sides of the signal terminal 20 in the plate thickness direction. That is, the insulating portion 40 is not limited to the case of being 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 is in the form of a film and has a shape along the contact portion 22 except for the elastic portion 21 and the first contact portion 23. Each of the insulating members 42 is configured such that its outline is positioned further outward than the outline of each of the signal terminals 20 when viewed in the thickness direction of each of the signal terminals 20. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of the signal in the high frequency region can be realized more easily. 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 formed of an insulating layer 43 provided over the entire inner surface of the first casing 10 forming the first housing portion 11, for example. With the above configuration, the inspection socket 1 capable of reducing the transmission loss of the signal in the high frequency region can be realized more easily.
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 into which the elastic portion 21 of the signal terminal 20 can 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 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 where the shoulder portion 223 of one contact portion 22 is in contact with the insulating layer 43 and the shoulder portion 223 of the other contact portion 22 is positioned outside the first housing 10.
The insulating layer 43 may be provided not on the entire first housing portion 11 but only on a part thereof.
As shown in fig. 14 to 16, the insulating portion 40 may be formed of a pair of third housings 44 that cover portions of both ends of the signal terminal 20 in the first direction X, except for the first contact portions 23, respectively.
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 body portion 221 of each contact portion 22 of each signal terminal 20. The second cylindrical portion 442 covers a part or the whole of the intermediate portion 222 of each contact portion 22 of each signal terminal 20, and has a dimension in the first direction X smaller than the first cylindrical portion 441 and a dimension in the radial direction 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 the signal in the high frequency region can be realized more easily.
