Description
この発明は、導電性を備えた第一部材と導電性を備えた第二部材との間に介在して、この第一部材と第二部材とを電気的に接続させるために用いられるスペーサ装置に関する。
The present invention is a spacer device that is interposed between a first member having conductivity and a second member having conductivity, and is used to electrically connect the first member and the second member. About.
電子機器や電気機器を構成する回路基板とこれらのシャーシなど、両者を所定の間隔を開けて組み合わせたときにさらにアース取りなどの観点から両者を電気的にも接続させることが求められる場合がある。
There are cases where it is required to electrically connect both of the circuit boards constituting these electronic devices and electric devices and their chassis from the viewpoint of grounding when they are combined at a predetermined interval. .
図１０～図１２に示される検討例のように、このような接続が求められる第一部材１に形成された取付穴１ａに挿入係合される係合部１００を一方側に備えると共に、他方側に前記第一部材１に電気的に接続することが求められる第二部材２００に対する弾性接触部２００とを有するスペーサ装置を利用すれば、この装置を第一部材１に取り付けた状態から第二部材２００を配置することで、両部材を電気的に接続させることができる。図１０～図１２中、符号３００で示されるのは、導電部材であり、この導電部材３００は第二部材２００に対しては前記弾性接触部２００の接触端２０１と第二部材２００との間に介在して第二部材２００の前記配置に伴ってこの第二部材２００に電気的に接続される。ここで図１０～図１２に示される検討例では、第二部材２００の配置時にはかかる弾性接触部２００は弾性変形されると共に、その接触端２０１は前記係合部１００の前記挿入中心を通る仮想の直線ｘの側方に位置されるようになっている。（図１１）しかるに、第二部材２００の配置時に弾性接触部２００の接触端２０１がこのように位置されると、この弾性接触部２００の弾性復帰力は前記仮想の直線ｘに沿った方向に作用されないため、第一部材１の板厚などによっては図１２に示されるようにスペーサ装置に傾きを生じさせることが考えられる。スペーサ装置にこのような傾きが生じると導電部材３００と第一部材１との接触状態は不安定なものとなる。
As shown in the study examples shown in FIGS. 10 to 12, the engagement portion 100 inserted and engaged with the attachment hole 1 a formed in the first member 1 where such connection is required is provided on one side, and the other If a spacer device having an elastic contact portion 200 with respect to the second member 200 that is required to be electrically connected to the first member 1 on the side is used, the device is attached to the first member 1 from the second state. By disposing the member 200, both members can be electrically connected. 10 to 12, reference numeral 300 indicates a conductive member. The conductive member 300 is located between the contact end 201 of the elastic contact portion 200 and the second member 200 with respect to the second member 200. The second member 200 is electrically connected to the second member 200 in accordance with the arrangement of the second member 200. Here, in the examination example shown in FIGS. 10 to 12, the elastic contact portion 200 is elastically deformed when the second member 200 is disposed, and the contact end 201 is assumed to pass through the insertion center of the engagement portion 100. It is located to the side of the straight line x. (FIG. 11) However, when the contact end 201 of the elastic contact portion 200 is positioned in this way when the second member 200 is disposed, the elastic return force of the elastic contact portion 200 is in a direction along the virtual straight line x. Since it is not acted on, depending on the thickness of the first member 1, etc., it is conceivable that the spacer device is inclined as shown in FIG. When such a tilt occurs in the spacer device, the contact state between the conductive member 300 and the first member 1 becomes unstable.
この発明が解決しようとする主たる問題点は、導電性を備えた第一部材と導電性を備えた第二部材との間に介在して、この第一部材と第二部材とを電気的に接続させるスペーサ装置におけるかかる接続状態を安定化させる点にある。
The main problem to be solved by the present invention is that the first member and the second member are electrically connected between the first member having conductivity and the second member having conductivity. This is to stabilize the connection state in the spacer device to be connected.
前記課題を達成するために、この発明にあっては、スペーサ装置を、導電性を備えた第一部材に形成された取付穴に挿入係合される係合部と、導電性を備えると共にこの第一部材との間に所定の間隔を開けて配置される第二部材に対する弾性接触部とを有するスペーサ主体に、
前記係合部を利用した第一部材への取り付けに伴って第一部材に電気的に接続される第一部分と、前記弾性接触部の接触端と第二部材との間に介在して第二部材の前記配置に伴ってこの第二部材に電気的に接続される第二部分とを、一体に備えた導電部材を組み合わせてなり、
前記弾性接触部の接触端は前記係合部の前記挿入中心を通る仮想の直線の側方に位置されると共に、この弾性接触部及び前記第二部分は第二部材の前記配置に伴って弾性変形して前記接触端が前記仮想の直線上に略位置されるようになっているものとした。 In order to achieve the above object, according to the present invention, the spacer device includes an engaging portion that is inserted into and engaged with a mounting hole formed in the first member having conductivity, and has conductivity. In the spacer main body having an elastic contact portion with respect to the second member arranged with a predetermined interval between the first member,
A first part electrically connected to the first member with attachment to the first member using the engaging part, and a second part interposed between the contact end of the elastic contact part and the second member In combination with the conductive member integrally provided with the second part electrically connected to the second member in accordance with the arrangement of the members,
The contact end of the elastic contact portion is positioned on the side of an imaginary straight line passing through the insertion center of the engagement portion, and the elastic contact portion and the second portion are elastic with the arrangement of the second member. It is assumed that the contact end is substantially positioned on the virtual straight line by deformation.
前記係合部を利用した第一部材への取り付けに伴って第一部材に電気的に接続される第一部分と、前記弾性接触部の接触端と第二部材との間に介在して第二部材の前記配置に伴ってこの第二部材に電気的に接続される第二部分とを、一体に備えた導電部材を組み合わせてなり、
前記弾性接触部の接触端は前記係合部の前記挿入中心を通る仮想の直線の側方に位置されると共に、この弾性接触部及び前記第二部分は第二部材の前記配置に伴って弾性変形して前記接触端が前記仮想の直線上に略位置されるようになっているものとした。 In order to achieve the above object, according to the present invention, the spacer device includes an engaging portion that is inserted into and engaged with a mounting hole formed in the first member having conductivity, and has conductivity. In the spacer main body having an elastic contact portion with respect to the second member arranged with a predetermined interval between the first member,
A first part electrically connected to the first member with attachment to the first member using the engaging part, and a second part interposed between the contact end of the elastic contact part and the second member In combination with the conductive member integrally provided with the second part electrically connected to the second member in accordance with the arrangement of the members,
The contact end of the elastic contact portion is positioned on the side of an imaginary straight line passing through the insertion center of the engagement portion, and the elastic contact portion and the second portion are elastic with the arrangement of the second member. It is assumed that the contact end is substantially positioned on the virtual straight line by deformation.
第一部材の取付穴に係合部を挿入係合させてこの第一部材にスペーサ装置を取り付けた状態から、第二部材を前記のように配置すると、弾性接触部及び第二部分は共に弾性変形して、弾性接触部の接触端は前記仮想の直線上に略位置され、第二部分は第二部材に押しつけられ電気的に接触される。かかる接触端は前記仮想の直線上に略位置されることから、弾性接触部の弾性復帰力もこの仮想の直線に沿った方向に作用される。これにより、第二部材の前記配置により第一部材の取付穴に挿入係合された係合部を傾かせるような力が作用されることはなく、導電部材の第一部分は適切且つ安定的に第一部材に押しつけられ続ける。
When the second member is arranged as described above from the state in which the engaging portion is inserted and engaged in the mounting hole of the first member and the spacer device is attached to the first member, the elastic contact portion and the second portion are both elastic. By deforming, the contact end of the elastic contact portion is substantially positioned on the virtual straight line, and the second portion is pressed against the second member and electrically contacted. Since the contact end is substantially positioned on the virtual straight line, the elastic return force of the elastic contact portion is also applied in the direction along the virtual straight line. Thereby, the force which inclines the engaging part inserted and engaged with the mounting hole of the first member by the arrangement of the second member is not applied, and the first portion of the conductive member is appropriately and stably. It continues to be pressed against the first member.
前記弾性接触部を、スペーサ主体におけるこの弾性接触部と係合部との間に形成されたコア部に基端を一体に連接させて、このコア部から次第に離れるように斜めに突き出された腕状をなすものとすると共に、コア部と弾性接触部との間の内隅に形成されたアール状をなす窪みによって、両者の連接箇所を薄肉にするようにしておくこともある。このようにした場合、第二部材の前記配置により弾性接触部はかかる連接箇所の一部に応力を集中させてしまうことなくこの連接箇所をおおむね中心としてスムースに弾性変形される。
The elastic contact portion is an arm projecting obliquely so as to gradually move away from the core portion with a base end integrally connected to a core portion formed between the elastic contact portion and the engagement portion in the spacer main body. In addition, the connecting portion of the two may be made thin by a rounded recess formed in the inner corner between the core portion and the elastic contact portion. In such a case, the elastic contact portion is elastically deformed smoothly with the connection portion as a center, without concentrating stress on a part of the connection portion by the arrangement of the second member.
前記弾性接触部を独立して二以上備えさせると共に、導電部材に各弾性接触部に対応した第二部分を形成させるようにしておくこともある。このようにした場合、第二部材における第一部材に向けられた面のうち、導電部材の第二部分が接する箇所が前記仮想の直線に直交する仮想の平面上に位置されない場合であっても、この導電部材の各第二部分をそれぞれ第二部材に適切に電気的に接触させることができる。
In some cases, two or more elastic contact portions are provided independently, and a second portion corresponding to each elastic contact portion is formed on the conductive member. Even if it does in this way, even if it is a case where the part which the 2nd part of an electrically-conductive member contacts among the surfaces toward the 1st member in a 2nd member is not located on the virtual plane orthogonal to the said virtual straight line. Each of the second portions of the conductive member can be appropriately brought into electrical contact with the second member.
また、前記スペーサ主体及び導電部材のいずれか一方に、これらの他方に形成された被掛合部に両者の組み合わせによって掛合される掛合部を形成させておくこともある。このようにしておけば、スペーサ主体と導電部材との組み合わせ状態を安定的に維持することができる。
Also, in either one of the spacer main body and the conductive member, a hooking portion that is hooked by a combination of both may be formed on the hooking portion formed on the other of them. In this way, the combined state of the spacer main body and the conductive member can be stably maintained.
また、前記導電部材の第二部分を、スリットにより分割された複数の接点から構成させるようにしておくこともある。このようにした場合、第二部材に対する導電部材の第二部分の接触安定性をより向上させることができる。
In addition, the second portion of the conductive member may be configured from a plurality of contacts divided by slits. When it does in this way, the contact stability of the 2nd part of the electrically-conductive member with respect to a 2nd member can be improved more.
この発明によれば、スペーサ装置による第一部材と導電性を備えた第二部材との電気的接続状態を効果的に安定化させることができる。
According to this invention, the electrical connection state between the first member by the spacer device and the second member having conductivity can be effectively stabilized.
以下、図１～図９に基づいて、この発明の典型的な実施の形態について、説明する。この実施の形態にかかるスペーサ装置Ｓは、導電性を備えた第一部材１と導電性を備えた第二部材２との間に介在して、この第一部材１と第二部材２とを電気的に接続させるために用いられるものである。具体的には、かかるスペーサ装置Ｓは、スペーサ主体３と導電部材４とを組み合わせて構成されており、第一部材１に取り付けられた状態において導電部材４の第一部分４０をこの第一部材１に電気的に接続させ、この後にこの第一部材１との間に所定の間隔を開けて第二部材２を配置したときに導電部材４の第二部分４１を第二部材２に弾性的に押しつけてこの第二部材２に電気的に接続させ、これによりスペーサ装置Ｓを介して第一部材１と第二部材２とを電気的に接続させるようになっている。かかるスペーサ装置Ｓは、例えば、電子機器や電気機器を構成する第一部材１としての基板と、これらを構成する第二部材２としての金属シャーシとの間に介在されて、両者を電気的に接続するなどの用途に用いられる。（図４）

The engaging portion 30 includes a core portion 30a protruding in a direction perpendicular to the first surface portion 32a from a middle position in the length direction of the rib-shaped pedestal 32b, and the core portions 30a on the left and right sides of the core portion 30a. One end of the arm is integrally connected to the tip of the arm portion 30b, and an arm portion 30b projecting obliquely toward the base portion side of the core portion 30a so as to move away from the core portion 30a as the base portion is approached. The distance between the engagement portions 30c farthest from the core portion 30a at the other arm end of the left and right arm portions 30b, 30b is slightly larger than the diameter of the mounting hole 1a.
また、この実施の形態にあっては、係合部３０と第一面部３２ａとの間に、前記リブ状台座３２ｂを挟んだ左右においてそれぞれ、弾性板片３３が配されている。各弾性板片３３は、リブ状台座３２ｂの長さと略等しい板幅を有し、その一辺をリブ状台座３２ｂの側部に一体に連接させてこのリブ状台座３２ｂから側方に向けて突き出すように設けられている。弾性板片３３の突きだし先端３３ａは、係合部３０の腕部３０ｂの係合箇所３０ｃよりも第一面部３２ａ側に位置されるが、弾性板片３３はその突きだし先端３３ａに向かうに連れてこの第一面部３２ａから次第に離れるように前記リブ状台座３２ｂから斜めに突き出されている。そして、この弾性板片３３の突きだし先端３３ａと係合部３０の腕部３０ｂの係合箇所３０ｃとの間の間隔が、第一部材１の厚さよりやや小さくなるように構成されている。
In this embodiment, elastic plate pieces 33 are arranged between the engaging portion 30 and the first surface portion 32a on the left and right sides of the rib-like pedestal 32b. Each elastic plate piece 33 has a plate width substantially equal to the length of the rib-shaped pedestal 32b, and one side thereof is integrally connected to a side portion of the rib-shaped pedestal 32b and protrudes from the rib-shaped pedestal 32b toward the side. It is provided as follows. The protruding tip 33a of the elastic plate piece 33 is positioned closer to the first surface portion 32a than the engaging portion 30c of the arm 30b of the engaging portion 30, but the elastic plate piece 33 is moved toward the protruding tip 33a. The rib-like pedestal 32b protrudes obliquely so as to gradually move away from the first surface portion 32a. And the space | interval between the protrusion tip 33a of this elastic board piece 33 and the engagement location 30c of the arm part 30b of the engaging part 30 is comprised so that it may become a little smaller than the thickness of the 1st member 1.

And the terminal on the right side of the plate portion 40b that is branched and positioned on the right side of the notched portion 40a is folded toward the notched portion 40a, and the one surface of the plate portion 40b and the folded portion 40c A gap 40d is formed in which the protruding end of the elastic plate piece 33 is accommodated. The second portion 41 is formed by forming a bent portion 41b at the end of the belt-like plate portion 40b having a width substantially equal to that of the elastic contact portion 31. A connecting plate portion 42 is formed between the first portion 40 and the second portion 41.
そして、この実施の形態にあっては、導電部材４はスペーサ主体３に次のように組み合わされている。（１）第一部分４０の板部４０ｂが弾性板片３３における第一面部３２ａに向けられた面に添装されるように、この板部４０ｂと折り返し箇所４０ｃとの間に弾性板片３３が挟み込み状に入れ込まれる。（２）連接板部４２はコア部３２の肉抜き穴３２ｅが形成されている二箇所の側面部３２ｄ、３２ｄの一方に添装される。（３）第二部分４１は弾性接触部３１における第二面部３２ｃに向けられた側と反対の面部に添装され、かつ、屈曲部４１ｂがこの弾性接触部３１の接触端３１ａの前方に位置される。すなわち、導電部材４の第一部分４０の板部４０ｂと連接板部４２とは略直角に交わり、第二部分４１は連接板部４２との間の内隅を鈍角に形成させながらこの連接板部４２より斜めに延びだしている。
In this embodiment, the conductive member 4 is combined with the spacer main body 3 as follows. (1) The elastic plate piece 33 is provided between the plate portion 40b and the folded portion 40c so that the plate portion 40b of the first portion 40 is attached to the surface of the elastic plate piece 33 facing the first surface portion 32a. Is inserted in a sandwiched manner. (2) The connecting plate portion 42 is attached to one of the two side surface portions 32d and 32d in which the hole 32e of the core portion 32 is formed. (3) The second portion 41 is attached to the surface portion of the elastic contact portion 31 opposite to the side directed to the second surface portion 32c, and the bent portion 41b is positioned in front of the contact end 31a of the elastic contact portion 31. Is done. That is, the plate portion 40b of the first portion 40 of the conductive member 4 and the connecting plate portion 42 intersect at a substantially right angle, and the second portion 41 forms the inner corner between the connecting plate portion 42 at an obtuse angle. It extends obliquely from 42.
係合部３０をもってスペーサ装置Ｓを第一部材１に取り付けると、第一部分４０は弾性板片３３共々弾性変形しながら折り返し箇所４０ｃの外面をこの第一部材１に押しつける。これにより、第一部分４０は第一部材１に電気的に接続される。
When the spacer device S is attached to the first member 1 with the engaging portion 30, the first portion 40 presses the outer surface of the folded portion 40 c against the first member 1 while being elastically deformed together with the elastic plate piece 33. As a result, the first portion 40 is electrically connected to the first member 1.
このように第一部材１にスペーサ装置Ｓを取り付けた状態から、第二部材２を前記のように配置すると、弾性接触部３１及び第二部分４１は共に弾性変形して、弾性接触部３１の接触端３１ａは前記仮想の直線ｘ上に略位置され、第二部分４１は第二部材２に押しつけられ電気的に接触される。（図４）かかる接触端３１ａは前記仮想の直線ｘ上に略位置されることから、弾性接触部３１の弾性復帰力もこの仮想の直線ｘに沿った方向に作用される。これにより、第二部材２の前記配置により第一部材１の取付穴１ａに挿入係合された係合部３０を傾かせるような力が作用されることはなく、第一部分４０は適切且つ安定的に第一部材１に押しつけられ続ける。
When the second member 2 is arranged as described above from the state in which the spacer device S is attached to the first member 1 as described above, the elastic contact portion 31 and the second portion 41 are both elastically deformed, and the elastic contact portion 31 The contact end 31a is substantially positioned on the virtual straight line x, and the second portion 41 is pressed against and electrically contacted with the second member 2. (FIG. 4) Since the contact end 31a is substantially positioned on the virtual straight line x, the elastic return force of the elastic contact portion 31 is also applied in the direction along the virtual straight line x. Thereby, the force which inclines the engaging part 30 inserted and engaged with the mounting hole 1a of the 1st member 1 by the said arrangement | positioning of the 2nd member 2 does not act, and the 1st part 40 is appropriate and stable. Thus, it continues to be pressed against the first member 1.
また、この実施の形態にあっては、前記コア部３２と弾性接触部３１との間の内隅に形成されたアール状をなす窪み３４によって、両者の連接箇所を薄肉にしている。かかる窪み３４は前記コア部３２と弾性接触部３１との間の外隅に向けて窪み３４、かつ、窪み３４の底をアール状としている。これにより、この実施の形態にあっては、第二部材２の前記配置により弾性接触部３１はかかる連接箇所の一部に応力を集中させてしまうことなくこの連接箇所をおおむね中心としてスムースに弾性変形される。
Further, in this embodiment, the connecting portion between the core portion 32 and the elastic contact portion 31 is made thin by a rounded recess 34 formed in the inner corner. The recess 34 has a recess 34 facing the outer corner between the core portion 32 and the elastic contact portion 31, and the bottom of the recess 34 has a rounded shape. As a result, in this embodiment, the elastic contact portion 31 is smoothly elastic with the connecting portion as a center in general without concentrating stress on a part of the connecting portion due to the arrangement of the second member 2. Transformed.
また、この実施の形態にあっては、独立した弾性接触部３１を二以上備えると共に、導電部材４に各弾性接触部３１に対応した第二部分４１を形成させている。これにより、第二部材２における第一部材１に向けられた面のうち、導電部材４の第二部分４１が接する箇所が前記仮想の直線ｘに直交する仮想の平面上に位置されない場合であっても、この導電部材４の各第二部分４１をそれぞれ第二部材２に適切に電気的に接触させることができるようになっている。
In this embodiment, two or more independent elastic contact portions 31 are provided, and the conductive member 4 is formed with a second portion 41 corresponding to each elastic contact portion 31. As a result, the portion of the surface of the second member 2 facing the first member 1 where the second portion 41 of the conductive member 4 contacts is not located on a virtual plane orthogonal to the virtual straight line x. However, each second portion 41 of the conductive member 4 can be appropriately brought into electrical contact with the second member 2.
また、この実施の形態にあっては、前記スペーサ主体３及び導電部材４のいずれか一方に、これらの他方に形成された被掛合部に両者の組み合わせによって掛合される掛合部を形成させている。この実施の形態にあっては、前記導電部材４の第一部分４０の板部４０ｂがスペーサ主体３の弾性板片３３における第一面部３２ａに向けられた面に添装されるように、この板部４０ｂと折り返し箇所４０ｃとの間にこの弾性板片３３を差し込みきった位置において、弾性板片３３に設けた掛合部としての突起３３ｂが入り込み掛合される被掛合部としての穴４０ｅが導電部材４の第一部分４０の前記板部４０ｂに設けられている。これにより、この実施の形態にあっては、スペーサ主体３と導電部材４との組み合わせ状態を安定的に維持できるようになっている。図示の例では、導電部材４の第二部分４１の連接板部４２との連接箇所と屈曲部４１ｂとの間に弾性接触部３１に外側から接する立ち上がり４１ｄ片が形成されており、これによってもかかる組み合わせ状態の安定化が図られている。
In this embodiment, either one of the spacer main body 3 and the conductive member 4 is formed with a hooking portion that is hooked to the hooked portion formed on the other of them by a combination of both. . In this embodiment, the plate portion 40b of the first portion 40 of the conductive member 4 is attached to the surface of the elastic plate piece 33 of the spacer main body 3 facing the first surface portion 32a. At the position where the elastic plate piece 33 is fully inserted between the plate portion 40b and the folded portion 40c, the hole 40e as the engaged portion into which the protrusion 33b as the engaging portion provided in the elastic plate piece 33 is inserted and engaged is electrically conductive. The first portion 40 of the member 4 is provided on the plate portion 40b. Thereby, in this embodiment, the combined state of the spacer main body 3 and the conductive member 4 can be stably maintained. In the illustrated example, a rising 41d piece that is in contact with the elastic contact portion 31 from the outside is formed between the connection portion of the second portion 41 of the conductive member 4 with the connection plate portion 42 and the bent portion 41b. Such a combined state is stabilized.
図９に示されるように、導電部材４の第二部分４１を、スリット４１ｅにより分割された複数の接点４１ｆから構成させるようにしておいても良い。この例では、第二部分４１の屈曲部４１ｂの突きだし端４１ｃから第二部分４１の長さ方向に沿って二条のスリット４１ｅ、４１ｅが形成されており、これにより第二部分４１の屈曲部４１ｂ側が三つの接点４１ｆ…４１ｆに分割されている。このようにした場合、第二部材２に対する導電部材４の第二部分４１の接触安定性をより向上させることができる。
As shown in FIG. 9, the second portion 41 of the conductive member 4 may be composed of a plurality of contacts 41f divided by slits 41e. In this example, two slits 41e and 41e are formed along the length direction of the second portion 41 from the protruding end 41c of the bent portion 41b of the second portion 41, whereby the bent portion 41b of the second portion 41 is formed. The side is divided into three contact points 41f ... 41f. When it does in this way, the contact stability of the 2nd part 41 of the electrically-conductive member 4 with respect to the 2nd member 2 can be improved more.
