[PTL 3] US 5,651,696 A
In order to attain the object described above, according to one embodiment of the present invention, there is provided a terminal mounting base configurable to mount to two different connectors, a push-type connector and a screw-type connector, according to claim 1.
Further, according to one embodiment of the present invention, there is provided a terminal system, including:
a plurality of the above-mentioned terminal systems,
the plurality of the terminal systems being arranged in a line so that the cable insertion port of each of the resin covers of the two connectors is oriented in an upward direction.
FIG. 2 (A) is an external view of the push-type speaker terminal 100A according to an embodiment of the present invention, and FIG. 2(B) is a cross-sectional view of a mounting part of a push-type connector 2 for the speaker terminal 100A.
The speaker terminal according to this embodiment may be applied as any one of push-type and screw-type (binding post-type) speaker terminals 100A and 100Bby selectively mounting a push-type connector 2 and a screw-type connector 3. Specifically, the speaker terminals 100A and 100B according to this embodiment each include a mounting base 1 to which both the push-type and screw-type connectors 2 and 3 may be mounted. First, after describing the configuration of the mounting base 1, which is a common component of the push-type speaker terminal 100A and the screw-type speaker terminal 100B, the overall configuration of each of the push-type and screw-type speaker terminals 100A and 100B is described.
As illustrated in FIGS. 1, the mounting base 1 includes two terminal plates 12, three lugs (two terminal lugs and one earth lug) (not shown), and a housing 11 to which those metal members are fixed.
The terminal part 121 is arranged on an end surface of a connector fixing boss part 111 of the housing 11. A through hole 1211 connecting to a stepped through hole 1112 formed in the connector fixing boss part 111 of the housing 11 is formed in the terminal part 121 as an insertion hole 123 for a stud 21 (see FIGS. 2) of the push-type connector 2 or a screw part 312 (see FIGS. 3) of the screw-type connector 3.
The stepped through hole 1112 includes a large-diameter portion 11121, which has a larger diameter than the through hole 1211 of the terminal part 121, and a small-diameter portion 11122, which is positioned on the back surface side of the housing body 110 with respect to the large-diameter portion 11121. When the screw-type connector 3 is to be mounted to the mounting base 1, a nut 5 that moves a male screw part 312 of the connector 3 in an axial direction is received in the large-diameter portion 11121 before mounting the terminal plate 12 (see FIGS. 3). On an inner peripheral surface of the large-diameter portion 11121, for example, a flat surface facing at least one of six flat surfaces formed on the outer periphery of the nut 5 is formed. The nut 5 is prevented from rotating in the large-diameter portion 11121 due to this flat surface coming into surface contact with the flat surface of the outer periphery of the nut 5. On the other hand, a flat surface 11123 for stopping rotation is formed in the axial direction on an inner periphery of the small-diameter portion 11122. When mounting the push-type connector 2 to the mounting base 1, a fixing part 2112 of the connector 2 is press-fitted into the small-diameter portion 11122. As a result, a nut 4 is fastened onto a screw part 212 of the connector 2 protruding on the back surface side of the housing body 110. At this point, the flat surface 11123 on the inner periphery of the small-diameter portion 11122 is in surface contact with a flat surface 2115 formed on the outer periphery of the fixing part 2112 of the push-type connector 2, which prevents the push-type connector 2 from rotating with respect to the housing body 110 (see FIGS. 2) .
In one of the three lug fixing boss parts 114, a screw hole 1141 passing from the front surface of the housing body 110 to the end surface of the lug fixing boss part 114 is formed. Further, a lug insertion slot (not shown) intersecting the screw hole 1141 is formed in an end surface of the lug fixing boss part 114, and one end portion of the earth lug is fitted into the lug insertion slot. A screw 6 (see FIGS. 4) inserted in a through hole formed in the rear panel 7 of the audio device is fastened into the screw hole 1141. As a result, the housing body 110 is fixed to the back side of the rear panel 7 of the audio device, and the one end portion of the earth lug is grounded to the case of the audio device by being electrically connected to the tip of the screw in the screw hole 1141.
FIG. 2 (A) is an external view of the push-type speaker terminal 100A according to this embodiment, and FIG. 2(B) is a cross-sectional view of a mounting part of the push-type connector 2 for the speaker terminal 100A.
The male screw part 212 of the stud 21 is caused to protrude on the back surface side of the housing body 110 from the stepped through hole 1112 of the connector fixing boss part 111 by press-fitting the fixing part 2112 into the small-diameter portion 11122 of the stepped through hole 1112 of the connector fixing boss part 111. When the nut 4 is fastened onto the male screw part 212, the stud 21 is in secure close contact with the terminal part 121, and the push-type connector 2 is fixed to the housing body 110 in a posture in which both openings of the cable insertion hole 2114 of the cap holding part 2111 face the cable insertion ports 1121 of the cover part 112.
FIG. 3 (A) is an external view of the screw-type speaker terminal 100B according to this embodiment, and FIG. 3(B) is a cross-sectional view of a mounting part of the screw-type connector 3 for the speaker terminal 100B.
As illustrated in FIGS. 4, two through holes 72 are formed for each audio channel 73 on the rear panel 7 of the audio device. The through holes 72 are arranged in a line in a horizontal direction.
In this state, the screw 6 inserted into the through hole 71 formed for each audio channel in the rear panel 7 of the audio device is fastened into the screw hole 1141 of the mounting base 1 of the speaker terminal 100A or 100B. As a result, each speaker terminal 100A or 100B is fixed to the rear panel 7 of the audio device, and the earth lug is grounded to the case of the audio device.
