The width of support 74 is narrower than base end part 71, and integral elongated is extended towards the edge part 17E one side approximate right angle of circuit substrate 17 from the end of the opposite side with connecting pin 71a of base end part 71, be configured in the first slot part 65a leave oral area far away in portion.That is, the back side almost parallel of support 74 and circuit substrate 17, and with the direction of the edge part 17E approximate right angle of circuit substrate 17 on elongated.In addition, the length of support 74 is shorter than base end part 71.
The width of flexible portion 72 is identical with support 74, and integral elongated is the form of extending from elongated end (with the end of the base end part 71 opposite sides) approximate right angle (promptly with base end part 71 almost parallels) of support 74.The length of flexible portion 72 is sizes shorter slightly than base end part 71.This flexible portion 72 is housed in the first slot part 65a, can obtain strain to the form that acutangulates with support 74 or the direction at obtuse angle tilts.
The width of brace 73 is identical with flexible portion 72, and integral elongated is stenostomatous roughly U font.First 73a of portion that brace 73 is extended to the direction of leaving circuit substrate 17 by the mode of turning back with the elongated end from flexible portion 72 and constitute to second 73b of portion that circuit substrate 17 extends in the mode that the elongated end from first 73a of portion turns back.In this brace 73, the narrow part of the interval stenosis of two 73a of portion, 73b is the form that is positioned at chimeric recess 63.That is, first 73a of portion is along the medial surface configuration of the edge part 17E from circuit substrate 17 of chimeric recess 63 side far away, and a part is housed in the first slot part 65a.Second 73b of portion is along the medial surface configuration near edge part 17E one side of circuit substrate 17 of chimeric recess 63, and a part is accommodated in the 3rd slot part 65c (being configured between a pair of location division 64).
Above-mentioned power supply board 16 is with parallel direction nearly base 13 assemblings of one side joint from the back side of circuit substrate 17 and base 13.Board connector 18 with respect to the mounting direction of this Relay linker 14 and discharge tube 15 with respect to the mounting direction of Relay linker 14 antithesis, in other words, discharge tube 15 is a direction parallel to each other with respect to the mounting direction of Relay linker 14 and the chimeric direction of board connector 18.During assembling, the wall portion 27 of Relay linker 14 and connect the embedded hole 17H of circuit substrates 17 along the substrate of this wall portion 27 configurations with connecting portion 33, insert the chimeric recess 63 of board connector 18, as Fig. 9 and shown in Figure 11, enter in the mode of clamp-oning between first 73a of portion and second 73b of portion, wall portion 27 and first 73a of portion butt, and substrate connecting portion 33 and second 73b of portion butt, brace 73 is so that first 73a of portion and second mode strain that the 73b of portion separates.Like this, Relay linker 14 and board connector 18 are chimeric, but relaying terminal 30 and lead-out terminal 70 conductings ground is connected, power supply board 16 is connected by Relay linker 14 with discharge tube 15, can be with electric power from power supply board 16 supply discharge tubes 15.In addition, after board connector 18 and Relay linker 14 reach regular chimerism, power supply board 16 is fixed on the base 13 by screw-clamped.
[effect of execution mode and effect]
(1) owing on circuit substrate 17, be formed with the embedded hole 17H that connects form, can realize and to be configured in forms circuit substrate 17 and back sides base 13 opposite sides with the board connector 18 that the relaying terminal 30 of base 13 connects.On the other hand, because the not restriction that causes with the position relation of base 13, electronic unit 19 can be installed in the back side of the circuit substrate 17 identical with board connector 18.That is, according to present embodiment, can realize 16 of the power supply boards that will connect with the relaying terminal 30 of base 13 with the back side of base 13 opposite sides single face Setup Type as installed surface.
(2) because the integral body (removing connecting pin 71a) of lead-out terminal 70 is housed in the housing 60, can protect the interference that is not subjected to from the foreign matter of outside.
(3) be connected with lead-out terminal 70 owing to relaying terminal 30 enters in the chimeric recess 63, can prevent the interference of foreign matter the coupling part of relaying terminal 30 and lead-out terminal 70.
(4) because by lead-out terminal 70 being limited to be formed on the location division 64 of the medial surface of chimeric recess 63, therefore restriction lead-out terminal 70 need not improve Flexurally rigid for the offset that prevents lead-out terminal 70 to the above-below direction occurrence positions skew parallel with the edge part 17E of circuit substrate 17.Like this, if reduce the Flexurally rigid of lead-out terminal 70, because the friction impedance that lead-out terminal 70 produces when being connected with relaying terminal 30 reduces, so the operability raising can realize relaying terminal 30 is connected with lead-out terminal 70 time.
(5) by by the base end part 71 that is fixed in housing 60, from base end part 71 (by support 74) but the brace 73 of the flexible portion 72 of the elastic bending of extending and the roughly U font that can flexibly clamp relaying terminal 30 that extends from flexible portion 72 constitutes lead-out terminals 70, the substrate of relaying terminal 30 contacts with second 73b of portion of free end side opposite with flexible portion 72 among 33 of connecting portions and two 73a of sheet portion, the 73b constituting brace 73.
Like this, in chimeric recess 63, when the substrate of relaying terminal 30 uses connecting portion 33 under the situation of flexible portion 72 1 sides occurrence positions skew relatively, because pushing down flexible portion 72, the integral body (first 73a of portion and second 73b of portion) of brace 73 makes its elastic bending, and move to flexible portion 72 1 sides (base end part 71 1 sides) integratedly with connecting portion 33 with substrate, so substrate remains connection status with connecting portion 33 and second 73b of portion.
In contrast, substrate with connecting portion 33 under the situation of the free end side opposite occurrence positions skew relatively with flexible portion 72, because 72 elastic bendings of flexible portion are little, second 73b of portion of free end side pushed down mobile by relaying terminal 30, therefore in this case, substrate also remains connection status with connecting portion 33 and second 73b of portion.At this moment, first 73a of portion and wall portion 27 separate.
(6) under the situation of a plurality of board connectors 18 and a plurality of relaying terminal 30 and row arrangement, might cause on lead-out terminal 70 and relaying terminal 30 direction side by side to produce offset by as the circuit substrate 17 of the nonmetal system of the installation parent of board connector 18 and not equal as the thermal coefficient of expansion between the metal base 13 of the installation parent of relaying terminal 30.
Therefore, as shown in Figure 9, the brace 73 of lead-out terminal 70 made going up with the roughly rectangular direction of the direction side by side of board connector 18 (left and right directions of Fig. 9) be the form of elongated extension, the substrate of relaying terminal 30 is made the parallel tabular of direction side by side (above-below direction of Fig. 9) with board connector 18 with connecting portion 33, and make substrate with the width dimensions of connecting portion 33 (size of parallel with the direction side by side of board connector 18 direction) for the size bigger than brace 73, brace 73 is contacted with connecting portion 33 with substrate.
Adopt this structure, because substrate is big in the size of the direction side by side of board connector 18 with connecting portion 33, even relaying terminal 30 and lead-out terminal 70 in direction occurrence positions skew side by side, also can keep brace 73 and the substrate connection status with connecting portion 33.
(7) in view of the edge part 17E configuration of board connector 18 along circuit substrate 17, and on lead-out terminal 70, apply high voltage, therefore in the time of might work as electric conductor near the edge part 17E of circuit substrate 17, between this electric conductor and lead-out terminal 70, produce leakage.
Therefore, in the present embodiment, utilize plastic housing 60 to surround lead-out terminal 70, and clamp insulation division 62 and be housed in the terminal accommodating portion 61 that is positioned at the opposite side of edge part 17E of circuit substrate 17, only be configured in to skew the zone of an opposite side with edge part 17E of housing 60 thus.Like this, the part approaching with the edge part 17E of circuit substrate 17 (insulation division 62) of board connector 18 is low-voltage region, because the edge part 17E of circuit substrate 17 and the distance of lead-out terminal 70 are elongated, so even the edge part 17E of electric conductor and circuit substrate 17 is approaching, does not worry between this electric conductor and lead-out terminal 70, producing yet and reveal.
