Description

本発明は、端子接続構造に関する。   The present invention relates to a terminal connection structure.

従来、板状をなす端子同士を重ね合わせて一対の挟持片の間に挿入し、両挟持片をねじ止めすることで互いに引き寄せて両端子を挟持する端子接続構造として、下記特許文献1に記載のものが知られている。このような端子接続構造によると、ねじ締結による倍力装置によって両挟持片を互いに引き寄せることができるため、両端子を強固に固定することができる。   Conventionally, as a terminal connection structure in which plate-shaped terminals are overlapped and inserted between a pair of sandwiching pieces and both the sandwiching pieces are screwed together to hold both terminals together, it is described in Patent Document 1 below. Things are known. According to such a terminal connection structure, since both clamping pieces can be pulled toward each other by a booster by screw fastening, both terminals can be firmly fixed.

特開平5−326041号公報JP-A-5-326041

しかしながら、上記の構成では、クリープと呼ばれる現象によって両挟持片が時間の経過とともに塑性変形し、両端子を挟み付ける力が低下する場合がある。この場合、端子に接続された電線が引っ張られるなどして両端子の接点部が外力を受けると、接点部が摺動して摩耗し、接点不良となってしまう。   However, in the above configuration, there is a case where both clamping pieces are plastically deformed with the lapse of time due to a phenomenon called creep, and the force for clamping both terminals may be reduced. In this case, if the contact part of both terminals receives external force by pulling the electric wire connected to the terminal, the contact part slides and wears, resulting in a contact failure.

本発明は上記のような事情に基づいて完成されたものであって、接点部の摩耗による接点不良を防ぐことを目的とする。   The present invention has been completed based on the above circumstances, and an object thereof is to prevent a contact failure due to wear of a contact portion.

本発明は、板状の第1本体部を有する第1端子と、板状の第2本体部を有する第2端子と、両本体部を合わせた状態で挟み付けることにより、両端子を接続状態に保持するばね部材と、を備えた端子接続構造であって、両端子の接点部は、第1本体部の合わせ面に形成された孔の周縁部と、第2本体部の合わせ面に膨出して形成された突起の外周側面とからなり、孔の周縁部は、突起が孔に嵌合した状態でばね部材のばね力を受けることによって突起の外周側面に対して弾性的に接触している構成としたところに特徴を有する。   In the present invention, a first terminal having a plate-like first main body part, a second terminal having a plate-like second main body part, and a state in which both the main body parts are put together are connected to each other. A contact member of both terminals, the contact portion of both terminals bulges on the peripheral edge of the hole formed in the mating surface of the first main body and the mating surface of the second main body. The outer peripheral side surface of the projection formed and the peripheral edge of the hole elastically contacts the outer peripheral side surface of the projection by receiving the spring force of the spring member with the projection fitted into the hole. It has the characteristics in the configuration.

このような構成によると、突起が孔に嵌合しているため、例えばいずれか一方の端子に接続された電線が引っ張られるなどした場合に、突起の外周側面が孔の周縁部に対して接触することになる。つまり、端子は一般に剛体とされており、容易に変形することはなく、外力に強い端子接続構造とすることができる。   According to such a configuration, since the protrusion is fitted in the hole, for example, when the electric wire connected to one of the terminals is pulled, the outer peripheral side surface of the protrusion contacts the peripheral edge of the hole. Will do. That is, the terminal is generally a rigid body, and is not easily deformed, and a terminal connection structure that is strong against external force can be obtained.

一方、ばね部材は、孔の周縁部と突起の外周側面とを弾性的に接触させることで、電線が引っ張られるなどした場合に、両端子の接点部に摩擦力を生じさせる機能を有している。この摩擦力によって接点部の摩耗が規制され、接点不良を防ぐことが可能となっている。また、クリープによって両端子が塑性変形した場合に、ばね部材によって両端子の歪みを吸収することができる。   On the other hand, the spring member has a function of generating a frictional force at the contact portions of both terminals when the electric wire is pulled by elastically contacting the peripheral edge portion of the hole and the outer peripheral side surface of the protrusion. Yes. This frictional force regulates the wear of the contact portion and can prevent contact failure. Further, when both terminals are plastically deformed by creep, the distortion of both terminals can be absorbed by the spring member.

本発明の実施の態様として、以下の構成が好ましい。
孔の周縁部が突起の外周側面に対して弾性的に接触した状態では、両本体部の合わせ面が互いに非接触とされている構成としてもよい。
このような構成によると、ばね部材のばね力を、両端子の接点部のみで受けるため、接点部に十分な接圧を付与することができる。
The following configuration is preferable as an embodiment of the present invention.
In a state where the peripheral portion of the hole is in elastic contact with the outer peripheral side surface of the protrusion, the mating surfaces of the two main body portions may be configured to be in non-contact with each other.
According to such a structure, since the spring force of a spring member is received only by the contact part of both terminals, sufficient contact pressure can be given to a contact part.

孔の周縁部に、突起の外周側面に対して面接触するテーパ面が周設されている構成としてもよい。
このような構成によると、両端子の接点部を面接触させることができるため、接点部を線接触させるよりも、接点部の摩耗を規制しやすくなる。
It is good also as a structure by which the taper surface which surface-contacts with respect to the outer peripheral side surface of a processus | protrusion is provided in the peripheral part of the hole.
According to such a configuration, since the contact portions of both terminals can be brought into surface contact, it is easier to regulate the wear of the contact portions than when the contact portions are brought into line contact.

突起は、筒状をなして貫通する形態とされている構成としてもよい。
このような構成によると、金属平板をプレス加工することによって突起を形成することができ、ダイキャストなどによって中実の突起を形成するよりも簡易に突起を形成することができる。
The protrusion may have a configuration that penetrates in a cylindrical shape.
According to such a configuration, the protrusion can be formed by pressing the metal flat plate, and the protrusion can be formed more easily than the solid protrusion formed by die casting or the like.

ばね部材は、接点部の両側に一対設けられており、両ばね部材が押圧部で連結されている構成としてもよい。
このような構成によると、接点部の両側で両本体部を挟み付けることができるため、接点部に対してバランス良く接圧を付与することができる。また、押圧部によって両ばね部材を押し込むことができるため、両ばね部材の取付作業が容易になる。
A pair of spring members may be provided on both sides of the contact portion, and both spring members may be connected by a pressing portion.
According to such a structure, since both main body parts can be clamped on both sides of the contact part, contact pressure can be applied to the contact part with a good balance. Moreover, since both spring members can be pushed in by a press part, the attachment operation | work of both spring members becomes easy.

本発明によれば、接点部の摩耗による接点不良を防ぐことができる。   According to the present invention, contact failure due to wear of the contact portion can be prevented.

<実施形態>
本発明の実施形態を図1ないし図9の図面を参照しながら説明する。本実施形態における端子接続構造は、図3に示すように、第1端子10と、第2端子20と、金属クリップ30とを備えて構成されている。
<Embodiment>
An embodiment of the present invention will be described with reference to the drawings of FIGS. As shown in FIG. 3, the terminal connection structure in the present embodiment includes a first terminal 10, a second terminal 20, and a metal clip 30.

第1端子10は、金属平板を打ち抜き加工、曲げ加工などを行うことによって形成されている。この第1端子10は、板状の第1本体部11と、第1本体部11の後方に形成されたバレル部12とを備えている。バレル部12は、一対のバレル片12Aを有しており、電線Wの端末部にて被覆W1を皮剥きすることで露出された芯線W2を両バレル片12Aによって圧着することにより第1端子10が電線Wに対して導通可能に接続されている。   The first terminal 10 is formed by punching or bending a metal flat plate. The first terminal 10 includes a plate-like first main body portion 11 and a barrel portion 12 formed behind the first main body portion 11. The barrel portion 12 has a pair of barrel pieces 12A, and the first terminal 10 is formed by crimping the core wire W2 exposed by peeling the coating W1 at the end portion of the electric wire W with both barrel pieces 12A. Is connected to the electric wire W so as to be conductive.

第1本体部11は前後方向に長い略方形とされており、その前側には、孔13が板厚方向に貫通して形成されている。孔13の両側には、第1本体部11の両側縁を折り曲げることによって形成された一対の側片14が形成されている。両側片14は対向状態をなすように略直角に折り曲げられており、第1本体部11の合わせ面(図3における下面)11Aからの突出高さがほぼ板厚一枚分となるように形成されている。   The 1st main-body part 11 is made into the substantially rectangular shape long in the front-back direction, The hole 13 is penetrated and formed in the plate | board thickness direction in the front side. A pair of side pieces 14 formed by bending both side edges of the first main body portion 11 are formed on both sides of the hole 13. Both side pieces 14 are bent at a substantially right angle so as to be opposed to each other, and formed so that the protruding height from the mating surface (lower surface in FIG. 3) 11A of the first main body 11 is about one sheet thickness. Has been.

両側片14の間には、平板状をなす雄タブ(図示せず)が前方から進入可能とされている。両側片14は、雄タブの上下寸法(雄タブの断面形状における板厚方向と直交する方向の寸法)よりもやや大きめの寸法だけ離れて配置されている。このため、雄タブを第1本体部11に対して前方から進入させると、上下一対の側片14によって雄タブを上下方向に位置決めすることができる。なお、雄タブを第1本体部11に対して下方から進入させる場合には、下側の側片14が不要となるため、上側の側片14のみによって雄タブを上下方向に位置決めすることができる。   A flat male tab (not shown) can enter between the side pieces 14 from the front. Both side pieces 14 are arranged apart by a dimension slightly larger than the vertical dimension of the male tab (the dimension in the direction perpendicular to the plate thickness direction in the cross-sectional shape of the male tab). For this reason, when the male tab is advanced from the front with respect to the first main body portion 11, the male tab can be positioned in the vertical direction by the pair of upper and lower side pieces 14. In addition, when making a male tab approach from the downward direction with respect to the 1st main-body part 11, since the lower side piece 14 becomes unnecessary, a male tab can be positioned to an up-down direction only by the upper side piece 14. FIG. it can.

第1本体部11において両側片14の後方には、第1本体部11の両側縁から側方に張り出す形態をなす一対の張り出し部15が形成されている。また、第1本体部11において両張り出し部15の間には、係止孔11Bが板厚方向に貫通して形成されている。   In the first body 11, a pair of projecting portions 15 are formed on the rear side of the both side pieces 14 so as to project laterally from both side edges of the first body 11. Further, in the first main body 11, a locking hole 11 </ b> B is formed between the projecting portions 15 so as to penetrate in the plate thickness direction.

このような第1端子10は、図1に示すように、合成樹脂製のハウジング40に横並びで複数が装着された状態とされている。このハウジング40は、機器側ケース(図示せず)の取付孔(図示せず)の内部に嵌合可能とされている。ハウジング40は、第1端子10を内部に収容可能な端子収容部41を有している。端子収容部41の前端開口42は、上下に長い略方形とされている。この前端開口42の左右両側には、一対のスリット43が開口縁から後方に向けて切り欠かれている。   As shown in FIG. 1, a plurality of such first terminals 10 are mounted side by side in a synthetic resin housing 40. The housing 40 can be fitted into an attachment hole (not shown) of a device side case (not shown). The housing 40 has a terminal accommodating portion 41 that can accommodate the first terminal 10 therein. The front end opening 42 of the terminal accommodating portion 41 has a substantially rectangular shape that is long in the vertical direction. On the left and right sides of the front end opening 42, a pair of slits 43 are cut away from the opening edge toward the rear.

前端開口42の外周面には、略門形をなすリテーナ50が側方から装着されている。このリテーナ50は、前端開口42の上下面に設けられた一対の係止突部44に対して係止可能な一対の係止片51を備えている。両係止片51が両係止突部44に係止した状態では、リテーナ50が側方に抜け止め状態に保持されるとともに、リテーナ50が前後方向に移動不能に保持される。   A retainer 50 having a substantially gate shape is attached to the outer peripheral surface of the front end opening 42 from the side. The retainer 50 includes a pair of locking pieces 51 that can be locked to a pair of locking protrusions 44 provided on the upper and lower surfaces of the front end opening 42. In a state where both the locking pieces 51 are locked to the both locking projections 44, the retainer 50 is held in a laterally prevented state and the retainer 50 is held immovably in the front-rear direction.

リテーナ50には、図2に示すように、両スリット43と第1本体部11の係止孔11Bとに差し込まれる差込片52が設けられている。差込片52が係止孔11Bに係止した状態では、第1端子10の前後方向における移動が規制されている。したがって、電線Wが後方に引っ張られるなどした場合に、第1端子10が端子収容部41の後方へ抜け出ることが規制される。ただし、係止孔11Bの内周面と差込片52の外周面との間には、成形に伴う寸法誤差を考慮して所定のクリアランスが設定されているため、このクリアランスの分だけ第1端子10の移動が許容されている。   As shown in FIG. 2, the retainer 50 is provided with an insertion piece 52 that is inserted into both the slits 43 and the locking hole 11 </ b> B of the first main body 11. In the state where the insertion piece 52 is locked in the locking hole 11B, the movement of the first terminal 10 in the front-rear direction is restricted. Accordingly, when the electric wire W is pulled backward, the first terminal 10 is restricted from coming out behind the terminal accommodating portion 41. However, since a predetermined clearance is set between the inner peripheral surface of the locking hole 11B and the outer peripheral surface of the insertion piece 52 in consideration of a dimensional error accompanying molding, the first clearance is set by the clearance. The terminal 10 is allowed to move.

第2端子20は、前後方向に長い略方形の第2本体部21を有している。この第2本体部21は、例えば機器側ケースの内部に配設された導電板の端末部として構成されている。第2本体部21の前側には、突起22が形成されている。この突起22は、第1本体部11との合わせ面(図3における上面)21Aから上方に膨出して形成されている。つまり、突起22は、先端が先細りとなる円錐台形状で、かつ、内部が中空の筒状をなしている。突起22の外周側面22Aは、合わせ面21Aに対して約45°の傾斜角度で立ち上がる傾斜面とされている。なお、突起22は、例えばバーリング加工や絞り加工などによって形成される。   The second terminal 20 has a substantially rectangular second main body 21 that is long in the front-rear direction. This 2nd main-body part 21 is comprised, for example as a terminal part of the electrically-conductive board arrange | positioned inside the apparatus side case. A protrusion 22 is formed on the front side of the second main body portion 21. The protrusion 22 is formed to bulge upward from a mating surface (upper surface in FIG. 3) 21A with the first main body 11. That is, the protrusion 22 has a truncated cone shape with a tapered tip and a hollow cylindrical shape inside. The outer peripheral side surface 22A of the protrusion 22 is an inclined surface that rises at an inclination angle of about 45 ° with respect to the mating surface 21A. The protrusion 22 is formed by, for example, burring or drawing.

金属クリップ30は、一対のばね部材31を押圧部32の両側に配置することで、全体として略門形をなしている。各ばね部材31は略U字状をなし、対向状態で配置された一対の弾性片を備えて構成されている。各ばね部材31は、両弾性片の基端部31Aを支点として自由端部31Bが互いに接近しまたは離れる方向に弾性的に撓み可能とされている。   The metal clip 30 has a substantially gate shape as a whole by arranging a pair of spring members 31 on both sides of the pressing portion 32. Each spring member 31 has a substantially U shape and is configured to include a pair of elastic pieces arranged in an opposing state. Each spring member 31 can be flexibly elastically bent in a direction in which the free end portions 31B approach or separate from each other with the base end portions 31A of both elastic pieces as fulcrums.

押圧部32は、基端部31Aよりも幅方向両側に突出している。押圧部32において基端部31Aよりも幅方向に張り出した部分は、複数の金属クリップ30を例えばカバー(図示せず)などに組み付けるための圧入部とされている。すなわち、複数の金属クリップ30を予めカバーに組み付けておき、このカバーをハウジング40に組み付けるようにすれば、複数の金属クリップ30を複数の端子金具対10、20に対して一度に組み付けることができる。   The pressing portion 32 protrudes on both sides in the width direction from the base end portion 31A. A portion of the pressing portion 32 that protrudes in the width direction from the base end portion 31A is a press-fit portion for assembling a plurality of metal clips 30 to, for example, a cover (not shown). That is, if a plurality of metal clips 30 are assembled to the cover in advance and the cover is assembled to the housing 40, the plurality of metal clips 30 can be assembled to the plurality of terminal fitting pairs 10 and 20 at once. .

さて、本実施形態の端子接続構造では、図4および図5に示すように、第1端子10の孔13に対して第2端子20の突起22を嵌合させて両本体部11,21の合わせ面11A,21Aを対面させた状態とし、この状態で金属クリップ30を用いて両本体部11,21を挟み付けることによって、両端子10,20が接続されている。すなわち、両端子10,20の接点部は、孔13の周縁部と、突起22の外周側面22Aとからなる。また、図6に示すように、ばね部材31の両弾性片は、両本体部11,21に対して弾性的に接触している。   Now, in the terminal connection structure of this embodiment, as shown in FIGS. 4 and 5, the projections 22 of the second terminal 20 are fitted into the holes 13 of the first terminal 10, so The terminals 10 and 20 are connected to each other by sandwiching both the main body portions 11 and 21 using the metal clip 30 in this state where the mating surfaces 11A and 21A face each other. That is, the contact portions of both terminals 10 and 20 are composed of the peripheral portion of the hole 13 and the outer peripheral side surface 22 </ b> A of the protrusion 22. Further, as shown in FIG. 6, both elastic pieces of the spring member 31 are in elastic contact with both the main body portions 11 and 21.

両端子10,20の接点部では、図7および図8に示すように、第1本体部11の孔13の周縁部と第2本体部21の突起22の外周側面22Aとが弾性的に接触している。より詳細には、図9に示すように、第1本体部11の孔13の周縁部における合わせ面11A側にテーパ面13Aが周設されており、このテーパ面13Aが突起22の外周側面22Aに対して弾性的に接触している。   As shown in FIGS. 7 and 8, at the contact portions of both terminals 10 and 20, the peripheral edge portion of the hole 13 of the first main body portion 11 and the outer peripheral side surface 22 </ b> A of the protrusion 22 of the second main body portion 21 are in elastic contact. is doing. More specifically, as shown in FIG. 9, a tapered surface 13 </ b> A is provided on the side of the mating surface 11 </ b> A in the peripheral portion of the hole 13 of the first main body portion 11, and this tapered surface 13 </ b> A is the outer peripheral side surface 22 </ b> A of the protrusion 22. Is elastically in contact with.

また、テーパ面13Aが突起22の外周側面22Aに対して弾性的に接触した状態では、両本体部11,21の合わせ面11A,21Aが互いに非接触とされている。このため、ばね部材31によるばね力は、両端子10,20の接点部のみで受けることになる。したがって、両端子10,20の接点部に対して十分な接圧を付与することができる。   Further, when the tapered surface 13A is in elastic contact with the outer peripheral side surface 22A of the protrusion 22, the mating surfaces 11A and 21A of the two main body portions 11 and 21 are not in contact with each other. For this reason, the spring force by the spring member 31 is received only at the contact portions of the terminals 10 and 20. Therefore, sufficient contact pressure can be applied to the contact portions of both terminals 10 and 20.

ここで、第2端子20は、機器側ケース内の導電板の端末部として移動不能に固定されているのに対して、第1端子10は、前記したように、係止孔11Bの内周面と差込片52の外周面との間のクリアランスにより、わずかではあるものの移動が許容されている。このため、電線Wが後方に引っ張られるなどした場合に、両端子10,20の接点部に負荷がかかることになる。   Here, the second terminal 20 is fixed so as not to move as a terminal portion of the conductive plate in the device-side case, whereas the first terminal 10 has the inner periphery of the locking hole 11B as described above. Due to the clearance between the surface and the outer peripheral surface of the insertion piece 52, a slight movement is allowed. For this reason, when the electric wire W is pulled backward, a load is applied to the contact portions of both terminals 10 and 20.

その点、両端子10,20の接点部は、孔13と突起22の嵌合部分における当たり合いによって構成されており、両端子10,20の母材となる金属平板は剛体とされているため、電線Wの引っ張りに対して変形することはない。また、両端子10,20の接点部には、両ばね部材31のばね力によって十分な接圧が付与されているため、接点部に大きな摩擦力を発生させることができる。この摩擦力によって孔13のテーパ面13Aが突起22の外周側面22Aに摺動しながら突起22から外れることを規制できる。これにより、電線Wの引っ張りによる両端子10,20の接点部の摩耗を規制して接点不良をなくすことができる。   In that respect, the contact portions of the terminals 10 and 20 are configured by contact at the fitting portions of the holes 13 and the protrusions 22, and the metal flat plate serving as the base material of the terminals 10 and 20 is a rigid body. The wire W is not deformed by the pulling of the electric wire W. Further, since a sufficient contact pressure is applied to the contact portions of both terminals 10 and 20 by the spring force of both spring members 31, a large frictional force can be generated at the contact portions. By this frictional force, the taper surface 13A of the hole 13 can be prevented from coming off the protrusion 22 while sliding on the outer peripheral side surface 22A of the protrusion 22. Thereby, abrasion of the contact part of both the terminals 10 and 20 by the tension | pulling of the electric wire W can be controlled, and a contact defect can be eliminated.

本実施形態は以上のような構成であって、続いてその作用を説明する。まず、両端子10,20の組み付け方法について図7および図8の図面を参照しながら簡単に説明する。最初に、第2本体部21を第1本体部11の両側片14の間に嵌め込んで突起22を孔13に嵌合させ、両本体部11,21の合わせ面11A,21Aを対面させた状態とする。   The present embodiment is configured as described above, and its operation will be described subsequently. First, a method of assembling both terminals 10 and 20 will be briefly described with reference to the drawings of FIGS. First, the second main body portion 21 was fitted between the both side pieces 14 of the first main body portion 11, the protrusions 22 were fitted into the holes 13, and the mating surfaces 11A and 21A of both the main body portions 11 and 21 faced each other. State.

次に、押圧部32を指で押し込むことにより、両本体部11,21の側方から金属クリップ30を装着する。これにより、両本体部11,21の合わせ面11A,21Aとは反対側の面がばね部材31の両弾性片によって挟み付けられる。この状態では、両端子10,20の接点部が、同接点部の前後両側に配置された両ばね部材31のばね力によってバランス良く接圧を受ける。こうして、両端子10,20が導通可能に接続される。   Next, the metal clip 30 is mounted from the side of both the main body parts 11 and 21 by pushing the pressing part 32 with a finger. Thereby, the surface on the opposite side to the mating surfaces 11 </ b> A and 21 </ b> A of both the main body portions 11 and 21 is sandwiched between both elastic pieces of the spring member 31. In this state, the contact portions of both terminals 10 and 20 receive contact pressure in a well-balanced manner by the spring force of both spring members 31 disposed on both front and rear sides of the contact portions. Thus, both terminals 10 and 20 are connected so as to be conductive.

第1端子10の後方には電線Wが接続されており、この電線Wが引っ張られるなどした場合、両端子10,20の接点部に負荷がかかる。しかし、両端子10,20の接点部は剛体によって構成され、電線Wの引っ張り方向(前後方向)に孔13のテーパ面13Aと突起22の外周側面22Aとが当たり合う構成とされているため、電線Wの引っ張りによって両端子10,20の接点部が変形するなどのおそれはない。   An electric wire W is connected behind the first terminal 10, and when the electric wire W is pulled, a load is applied to the contact portions of both the terminals 10 and 20. However, the contact portions of both terminals 10 and 20 are formed of a rigid body, and the tapered surface 13A of the hole 13 and the outer peripheral side surface 22A of the protrusion 22 are in contact with each other in the pulling direction (front-rear direction) of the wire W There is no fear that the contact portions of the terminals 10 and 20 are deformed by the pulling of the electric wire W.

要するに、ばね部材31は、両端子10,20の接点部の摩耗を規制するために両端子10,20を固定する固定部材ではなく、両端子10,20の接点部に摩擦力を発生させるための垂直抗力を付与するに過ぎない。このため、ばね部材31を剛体で構成する必要はない。すなわち、本実施形態の端子接続構造によると、電線Wの引っ張りなどの外力に対して、ばね部材31が両端子10,20の接点部に与える接圧によって抗するのではなく、剛体である両本体部11,21自身で受ける構造であるため、外力に強い端子接続構造とすることができる。   In short, the spring member 31 is not a fixing member that fixes both the terminals 10 and 20 in order to restrict the wear of the contact parts of the both terminals 10 and 20 but generates a frictional force at the contact parts of the both terminals 10 and 20. It only gives the normal drag of. For this reason, it is not necessary to comprise the spring member 31 with a rigid body. That is, according to the terminal connection structure of this embodiment, the spring member 31 does not resist the external force such as the pulling of the electric wire W by the contact pressure applied to the contact portions of the both terminals 10 and 20 but is both rigid bodies. Since it is a structure received by the main body parts 11 and 21 itself, a terminal connection structure that is resistant to external force can be obtained.

以上のように本実施形態では第1本体部11に孔13を設け、第2本体部21に突起22を設け、この突起22を孔13に嵌合させて接点部を構成したから、電線Wの引っ張りなどに対して両端子10,20の接点部を強固に保持できる。また、両ばね部材31のばね力を両端子10,20の接点部に付与することで、接点部に大きな摩擦力を発生させることができる。   As described above, in the present embodiment, the hole 13 is provided in the first main body 11, the protrusion 22 is provided in the second main body 21, and the contact 22 is configured by fitting the protrusion 22 into the hole 13. It is possible to firmly hold the contact portions of both terminals 10 and 20 against pulling of the wire. Further, by applying the spring force of both spring members 31 to the contact portions of both terminals 10 and 20, a large frictional force can be generated at the contact portions.

また、両端子10,20の接点部に接圧が付与された状態では、両本体部11,21の合わせ面11A,21Aが非接触となっているから、接点部に対してより大きな接圧を付与することができる。このとき、接点部の両側に一対のばね部材31を配置したから、接点部にバランス良く接圧を付与することができる。さらに、孔13の周縁部にテーパ面13Aを周設したから、両端子10,20の接点部にて線接触させることが可能となり、接点部の摩耗を規制することができる。なお、突起22を円筒状に形成したから、切削加工などによって突起22を容易に形成することができる。   Further, when contact pressure is applied to the contact portions of both terminals 10 and 20, the mating surfaces 11A and 21A of both main body portions 11 and 21 are not in contact with each other, so that a larger contact pressure is applied to the contact portions. Can be granted. At this time, since the pair of spring members 31 are arranged on both sides of the contact portion, the contact pressure can be applied to the contact portion with a good balance. Furthermore, since the tapered surface 13A is provided around the peripheral portion of the hole 13, it is possible to make line contact at the contact portions of both the terminals 10 and 20, and the wear of the contact portions can be regulated. Since the protrusion 22 is formed in a cylindrical shape, the protrusion 22 can be easily formed by cutting or the like.
