Description

本発明は、ピン端子、端子群及びコネクタに関する。   The present invention relates to a pin terminal, a terminal group, and a connector.
従来、基板用端子をコネクタハウジングの端子保持穴に圧入保持する場合の端子保持構造については、種々のものが知られている。例えば特許文献1に記載の基板用コネクタの端子保持構造は、図10の(a),(b)に示すように、端子保持壁501を備えたコネクタハウジング503と、端子保持壁501に貫通して設けられた端子保持穴505(端子挿入孔)に圧入され、端子保持穴505に係止部で保持される基板用端子507(ピン端子)と、を含んで構成される。この端子保持構造は、基板用端子507の幅方向両側に突設され、端子保持穴505の両側壁509に圧入されるように形成された一対の後部係止突起511と、後部係止突起511の端子圧入方向(図10の矢印a方向)の前方に端子保持穴505の両側壁509に圧入されるように形成された一対の前部係止突起513とを含んで形成される。そして、後部係止突起511と前部係止突起513とは、異なる形状とされる。   Conventionally, various types of terminal holding structures in the case of press-fitting and holding board terminals in terminal holding holes of a connector housing are known. For example, as shown in FIGS. 10A and 10B, a terminal holding structure for a board connector described in Patent Document 1 penetrates through a connector housing 503 having a terminal holding wall 501 and a terminal holding wall 501. And a board terminal 507 (pin terminal) that is press-fitted into the terminal holding hole 505 (terminal insertion hole) and is held in the terminal holding hole 505 by a locking portion. This terminal holding structure is provided with a pair of rear locking projections 511 that protrude from both sides of the board terminal 507 in the width direction and are press-fitted into both side walls 509 of the terminal holding holes 505, and a rear locking projection 511. And a pair of front locking projections 513 formed so as to be press-fitted into both side walls 509 of the terminal holding hole 505 in the front of the terminal press-fitting direction (direction of arrow a in FIG. 10). The rear locking protrusion 511 and the front locking protrusion 513 have different shapes.
また、特許文献2に記載の圧入端子は、図11に示すように、樹脂製のコネクタハウジングに形成されたピン保持孔(端子挿入孔)に圧入される圧入端子515(ピン端子)であって、4つの側面を有する断面が矩形状の角線材からなる。角線材からなる圧入端子515は、ピン保持孔に圧入される部分の4つの側面に突起517,519が設けられている。これら突起517,519は、いくつかが他の突起517,519に対して角線材の長手方向に変位して形成される。変位された各突起517,519は、側面から突出する突出量が異なって形成されている。   The press-fit terminal described in Patent Document 2 is a press-fit terminal 515 (pin terminal) that is press-fitted into a pin holding hole (terminal insertion hole) formed in a resin connector housing, as shown in FIG. A cross section having four side surfaces is made of a rectangular wire having a rectangular shape. The press-fit terminal 515 made of a rectangular wire is provided with projections 517 and 519 on the four side surfaces of the portion press-fitted into the pin holding hole. Some of these protrusions 517 and 519 are formed by being displaced in the longitudinal direction of the rectangular wire with respect to the other protrusions 517 and 519. The displaced protrusions 517 and 519 are formed with different protrusion amounts protruding from the side surfaces.

特許文献1に開示された基板用コネクタの端子保持構造では、角線材を使用して形成された基板用端子507に、圧入部である後部係止突起511と前部係止突起513とが2箇所設けられている。このような構造では、図12の(a),(b)に示すように、後部係止突起511の高さX2が前部係止突起513の高さX1よりも低くされ、後部係止突起511の幅Y2が前部係止突起513の幅Y1よりも広くされることで、端子保持効果が高められている。しかしながら、幅Y1よりも狭い幅Y3を有する端子保持穴505に1番目(挿入方向先)の前部係止突起513が挿入されると、両側壁509における2番目(挿入方向後)の後部係止突起511があたる部分が幅Y4ずつ削られるため、2番目の後部係止突起511の保持力が低下することを完全に抑制することはできず、目的とした保持力よりも低くなってしまう。
なお、端子保持力は前部係止突起513の幅Y1及び後部係止突起511の幅Y2を拡大することにより向上するが、これら前部係止突起513及び後部係止突起511は、角線材をプレスにて潰して作成するため、元の断面積以上の面積となる突起形状を作成することができず、幅方向に広げるのには限界がある。
In the terminal holding structure for a board connector disclosed in Patent Document 1, two rear latching protrusions 511 and two front latching protrusions 513 that are press-fitting portions are provided on a board terminal 507 formed using a square wire. There are places. In such a structure, as shown in FIGS. 12A and 12B, the height X2 of the rear locking projection 511 is made lower than the height X1 of the front locking projection 513, so that the rear locking projection. By making the width Y2 of 511 wider than the width Y1 of the front locking protrusion 513, the terminal holding effect is enhanced. However, when the first (insertion direction ahead) front locking protrusion 513 is inserted into the terminal holding hole 505 having a width Y3 that is narrower than the width Y1, the second (after insertion direction) rear portion engagement on both side walls 509. Since the portion corresponding to the stop protrusion 511 is scraped by the width Y4, it is impossible to completely suppress the decrease in the holding force of the second rear locking protrusion 511, and it becomes lower than the target holding force. .
The terminal holding force is improved by increasing the width Y1 of the front locking projection 513 and the width Y2 of the rear locking projection 511. The front locking projection 513 and the rear locking projection 511 are rectangular wires. Therefore, it is impossible to create a protrusion shape having an area larger than the original cross-sectional area, and there is a limit to expanding in the width direction.
また、特許文献2に開示された圧入端子515は、幅方向W及び高さ方向Hに突出する複数の突起517,519を備えている。このような構造では、角線材を用いて圧入部である複数の突起517,519を形成する場合、角線材送り方向に対して上側及び横側から押圧しなければならず、圧入部形成用の設備が大型化する。   The press-fit terminal 515 disclosed in Patent Document 2 includes a plurality of protrusions 517 and 519 that protrude in the width direction W and the height direction H. In such a structure, when forming a plurality of protrusions 517 and 519 that are press-fitting portions using a square wire, it is necessary to press from the upper side and the lateral side with respect to the square wire feed direction, Larger equipment.
本発明は上記状況に鑑みてなされたもので、その目的は、挿入方向前方の圧入部の圧入によって挿入方向後方の圧入部の保持力に影響を与えることがなく、高い保持力が得られるピン端子、端子群及びコネクタを提供することにある。   The present invention has been made in view of the above situation, and its purpose is to provide a high holding force without affecting the holding force of the press-fitting part at the rear of the insertion direction by the press-fitting of the press-fitting part at the front of the insertion direction. It is to provide a terminal, a terminal group, and a connector.
本発明に係る上記目的は、下記構成により達成される。
(1) コネクタハウジングの端子挿入孔に圧入保持されるピン端子であって、前記ピン端子の幅方向両側縁から突出した一対の圧入部が前記ピン端子の挿入方向に沿って間隔を隔てて複数対形成されており、複数対の前記圧入部は、それぞれの対が、前記ピン端子の幅方向に対して直交する高さ方向に沿って互いに異なる位置に設けられていることを特徴とするピン端子。
The above object of the present invention is achieved by the following configuration.
(1) A pin terminal press-fitted and held in a terminal insertion hole of the connector housing, wherein a plurality of a pair of press-fitting portions protruding from both side edges in the width direction of the pin terminal are spaced apart along the insertion direction of the pin terminal. A plurality of pairs of the press-fitting portions are formed in pairs, and the respective pairs are provided at different positions along the height direction orthogonal to the width direction of the pin terminals. Terminal.
上記(1)の構成のピン端子によれば、コネクタハウジングの端子挿入孔にピン端子が挿入される際には、先ず挿入方向前方の圧入部が先に圧入される。そして、挿入方向後方の圧入部が圧入される際には、挿入方向前方の圧入部と高さ方向に異なる位置で圧入される。このため、ピン端子は、挿入方向後方の圧入部が圧入される端子挿入孔の圧入部分(両側壁)を挿入方向前方の圧入部が削ることはない。そこで、本構成のピン端子は、挿入方向前方の圧入部の圧入によって挿入方向後方の圧入部の保持力に影響を与えることがなく、高い保持力が得られる。
なお、本構成のピン端子によれば、ピン端子の挿入方向前方の圧入部と挿入方向後方の圧入部とを同一のプレス型で(例えば上下側から)、プレスして形成できる。また、挿入方向前方の圧入部を形成するためのプレス型と、挿入方向後方の圧入部を形成するためのプレス型とが別体にされても、これらのプレス型を並列配置し、上下側から同時にプレスすればよい。
According to the pin terminal having the above configuration (1), when the pin terminal is inserted into the terminal insertion hole of the connector housing, first, the press-fitting portion forward in the insertion direction is first press-fitted. When the press-fitting part at the rear in the insertion direction is press-fitted, it is press-fitted at a position different from the press-fitting part at the front in the insertion direction in the height direction. For this reason, in the pin terminal, the press-fit portion in the insertion direction does not cut the press-fit portion (both side walls) of the terminal insertion hole into which the press-fit portion in the rear in the insertion direction is press-fit. Therefore, the pin terminal of this configuration can obtain a high holding force without affecting the holding force of the press-fitting portion at the rear of the insertion direction by the press-fitting of the press-fitting portion at the front of the insertion direction.
In addition, according to the pin terminal of this structure, the press-fit part ahead of the insertion direction of a pin terminal and the press-fit part of the insertion direction back can be pressed and formed by the same press die (for example, from the upper and lower sides). Moreover, even if the press die for forming the press-fitting portion in the front in the insertion direction and the press die for forming the press-in portion in the rear in the insertion direction are separated, these press dies are arranged in parallel, Press at the same time.
(2) 複数対の前記圧入部は、それぞれの対が、互いに異なる突出高さで形成されていることを特徴とする上記(1)の構成のピン端子。 (2) The plurality of pairs of press-fitting portions, wherein each pair is formed with different protruding heights.
上記(2)の構成のピン端子によれば、挿入方向に沿った任意の位置における複数対の圧入部の突出高さをそれぞれ変えることで、所望の一対の圧入部の保持力を任意に設定することが可能となる。また、ピン端子の圧入時の圧入抵抗と、その圧入によって得られる保持力とは一般的に比例するので、高い保持力を得ようとすれば、圧入抵抗が増大する。これを勘案し、例えば、複数対の圧入部は、ピン端子の挿入方向先端に近づくにしたがってそれぞれ突出高さが低くなるように形成することができる。この場合、複数対の圧入部は、端子挿入孔に挿入されるピン端子の挿入深さが深くなるにしたがって、端子挿入孔に対する圧接力が段階的に大きくなって端子挿入孔の内面を徐々に変形させながら圧入されるので、挿入性が向上する。   According to the pin terminal configured as described in (2) above, the holding force of the desired pair of press-fitting parts can be set arbitrarily by changing the protruding heights of the plurality of pairs of press-fitting parts at arbitrary positions along the insertion direction. It becomes possible to do. In addition, since the press-fitting resistance at the time of press-fitting the pin terminal is generally proportional to the holding force obtained by the press-fitting, if a high holding force is to be obtained, the press-fitting resistance increases. Taking this into consideration, for example, the plurality of pairs of press-fitting portions can be formed such that the protruding heights become lower as they approach the distal end of the pin terminal in the insertion direction. In this case, in the plurality of pairs of press-fitting portions, as the insertion depth of the pin terminal inserted into the terminal insertion hole increases, the pressure contact force with respect to the terminal insertion hole gradually increases, and the inner surface of the terminal insertion hole gradually increases. Since it is press-fitted while being deformed, insertability is improved.
(3) 上記(1)又は(2)に記載の複数の前記ピン端子が、長尺の金属線材を所定長で切断して形成され、前記コネクタハウジングの複数の端子挿入孔にそれぞれ圧入保持される端子群であって、全長が異なる前記ピン端子を含む前記複数のピン端子は、前記圧入部よりも挿入方向後端側の同じ位置に、前記ピン端子の幅方向両側縁から突出した一対の圧入支持部がそれぞれ形成されており、前記圧入支持部の挿入方向後端側面が前記端子挿入孔に対する圧入時の反力を支持することを特徴とする端子群。 (3) The plurality of pin terminals described in the above (1) or (2) are formed by cutting a long metal wire at a predetermined length, and are press-fitted and held in the plurality of terminal insertion holes of the connector housing, respectively. The plurality of pin terminals including the pin terminals having different overall lengths are a pair of terminals protruding from both side edges in the width direction of the pin terminals at the same position on the rear end side in the insertion direction than the press-fitting portion. A terminal group in which a press-fit support portion is formed, and a rear end side surface in the insertion direction of the press-fit support portion supports a reaction force during press-fitting with respect to the terminal insertion hole.
上記(3)の構成の端子群によれば、端子群の複数のピン端子がコネクタハウジングの複数の端子挿入孔にそれぞれ圧入される際には、複数のピン端子の異なる全長に係わらず挿入方向先端から同じ位置に形成された圧入支持部の挿入方向後端側面が挿入治具等に支持され、コネクタハウジングの端子挿入孔へ圧入されるピン端子の圧入反力を常に受けることができる。そこで、長さの異なるピン端子をコネクタハウジングの複数の端子挿入孔に同じストロークで連続挿入することができる。その結果、端子圧入装置を小型化でき、コネクタの製造コストを低減できる。また、本構成のピン端子によれば、ピン端子の挿入方向前方及び挿入方向後方の各圧入部と、圧入支持部とを同一のプレス型で(例えば上下側から)、プレスして形成できる。   According to the terminal group having the configuration of (3) above, when the plurality of pin terminals of the terminal group are press-fitted into the plurality of terminal insertion holes of the connector housing, the insertion direction regardless of the different total lengths of the plurality of pin terminals. The rear end side surface in the insertion direction of the press-fit support portion formed at the same position from the front end is supported by an insertion jig or the like, and can always receive the press-fit reaction force of the pin terminal press-fitted into the terminal insertion hole of the connector housing. Therefore, pin terminals having different lengths can be continuously inserted into the plurality of terminal insertion holes of the connector housing with the same stroke. As a result, the terminal press-fitting device can be reduced in size, and the manufacturing cost of the connector can be reduced. Further, according to the pin terminal of the present configuration, the press-fitting portions at the front and rear of the pin terminal in the insertion direction and the press-fitting support portion can be formed by pressing with the same press die (for example, from the upper and lower sides).
(4) 前記ピン端子は、予めメッキ処理が施された前記金属線材によって形成されることを特徴とする上記(3)に記載の端子群。 (4) The terminal group according to (3), wherein the pin terminal is formed of the metal wire that has been plated in advance.
上記(4)の構成の端子群によれば、ピン端子は、予めメッキ処理が施された長尺の導電性金属材料からなる金属線材を所定長さに切断することで形成されたものであるので、プレス加工で形成するピン端子を用いた場合と比較し、歩留りの向上を図ることができる。また、ピン端子の電気接触部にはメッキのない破断面が形成されないので、煩雑な後メッキ処理や面取りを行うことなく、良好な耐食性及び相手端子との良好な接続信頼性を確保することができ、高い品質を確保できる。
しかも、予めメッキした金属線材からなるピン端子は、ダレやバリがなく、しかも、全周にわたってメッキが均一に施されている。そこで、コネクタハウジングの端子挿入孔がシール材により封止されるような場合には、ピン端子の周囲におけるシール材との密着性を均一にすることができ、良好なシール性を確保できる。
According to the terminal group configured as described in (4) above, the pin terminal is formed by cutting a metal wire made of a long conductive metal material that has been previously plated to a predetermined length. Therefore, the yield can be improved as compared with the case of using a pin terminal formed by press working. In addition, since the fracture surface without plating is not formed in the electrical contact portion of the pin terminal, it is possible to ensure good corrosion resistance and good connection reliability with the counterpart terminal without performing complicated post-plating treatment or chamfering. And high quality can be secured.
Moreover, the pin terminal made of a pre-plated metal wire has no sagging or burrs, and is plated uniformly over the entire circumference. Therefore, when the terminal insertion hole of the connector housing is sealed with the sealing material, the adhesion with the sealing material around the pin terminal can be made uniform, and a good sealing property can be secured.
(5) 複数の端子挿入孔を有するコネクタハウジングと、前記複数の端子挿入孔にそれぞれ圧入保持される上記(1)又は(2)に記載の複数の前記ピン端子と、を備えたコネクタ。 (5) A connector comprising: a connector housing having a plurality of terminal insertion holes; and the plurality of pin terminals according to the above (1) or (2) that are press-fitted and held in the plurality of terminal insertion holes.
上記(5)の構成のコネクタによれば、ピン端子における挿入方向後方の圧入部がコネクタハウジングの端子挿入孔に圧入される際には、挿入方向前方の圧入部と高さ方向に異なる位置で圧入される。このため、コネクタハウジングは、挿入方向後方の圧入部が圧入される端子挿入孔の圧入部分が、挿入方向前方の圧入部により削られることがない。そこで、本構成のコネクタは、ピン端子の挿入方向前方の圧入部の圧入によって挿入方向後方の圧入部の保持力が影響を受けることがなく、ピン端子の保持力を向上させることができる。   According to the connector having the above configuration (5), when the press-fitting portion on the rear side in the insertion direction of the pin terminal is press-fitted into the terminal insertion hole of the connector housing, the press-fitting portion on the front side in the insertion direction is different in the height direction. Press fit. For this reason, in the connector housing, the press-fitting portion of the terminal insertion hole into which the press-fitting portion at the rear in the insertion direction is press-fitted is not scraped by the press-fitting portion at the front in the insertion direction. Therefore, the connector of this configuration can improve the holding force of the pin terminal without being affected by the holding force of the press-fitting portion at the rear of the insertion direction due to the press-fitting of the press-fitting portion at the front of the pin terminal in the insertion direction.
本発明に係るピン端子、端子群及びコネクタによれば、挿入方向前方の圧入部の圧入によって挿入方向後方の圧入部の保持力が影響を受けることがなく、ピン端子の保持力を向上させることができる。   According to the pin terminal, the terminal group, and the connector according to the present invention, the holding force of the press-fitting portion at the rear of the insertion direction is not affected by the press-fitting of the press-fitting portion at the front of the insertion direction, and the holding force of the pin terminal is improved. Can do.

When a plurality of terminal insertion holes 19 arranged in a row are arranged in six stages in the vertical direction as in the present embodiment, the terminal group 11 has six different types of pin terminals 15 (that is, shown in FIG. 5). Pin terminal 25, pin terminal 26, pin terminal 27, pin terminal 28, pin terminal 29, pin terminal 30).
全長が異なるピン端子25,26,27,28,29,30を含む複数のピン端子15は、挿入方向先端から同じ位置に、一対の圧入支持部31(図4参照)がそれぞれ形成される。一対の圧入支持部31は、ピン端子15の幅方向両側縁から突出される。圧入支持部31は、例えば、長さ方向(軸方向)の中間部分を長さ方向に直交する方向(軸直交方向)で鍛圧して側方に突出させることにより形成される。ここで、ピン端子15は、軸方向の一端側が挿入方向(図1の矢印a方向)とされる。圧入支持部31は、挿入方向後端側面33(図8参照)が端子挿入孔19に対する圧入時の反力を支持する。すなわち、圧入支持部31の挿入方向後端側面33は、端子圧入装置の挿入ヘッド39(図7参照)による押圧力F(図8参照)によって押される押圧面となる。本実施形態において、圧入支持部31は、平面視で矩形状に形成されるが、挿入方向後端側面33が圧入時の反力を支持できるものであればその形状に限定されない。   A plurality of pin terminals 15 including pin terminals 25, 26, 27, 28, 29, and 30 having different overall lengths are respectively formed with a pair of press-fit support portions 31 (see FIG. 4) at the same position from the distal end in the insertion direction. The pair of press-fit support portions 31 protrude from both side edges of the pin terminal 15 in the width direction. The press-fit support portion 31 is formed, for example, by forging an intermediate portion in the length direction (axial direction) in a direction (axial orthogonal direction) perpendicular to the length direction and projecting laterally. Here, as for the pin terminal 15, the one end side of an axial direction is made into the insertion direction (arrow a direction of FIG. 1). In the press-fit support portion 31, the rear end side surface 33 (see FIG. 8) in the insertion direction supports a reaction force during press-fitting with respect to the terminal insertion hole 19. That is, the rear end side surface 33 in the insertion direction of the press-fit support portion 31 becomes a pressing surface that is pressed by the pressing force F (see FIG. 8) by the insertion head 39 (see FIG. 7) of the terminal press-fitting device. In the present embodiment, the press-fit support portion 31 is formed in a rectangular shape in plan view, but is not limited to that shape as long as the rear end side surface 33 in the insertion direction can support a reaction force during press-fit.
また、各ピン端子15には、圧入支持部31よりも挿入方向先端側に、幅方向両側縁から突出した一対の圧入部35と圧入部37とがピン端子の挿入方向に沿って間隔を隔てて複数対(本実施形態では2対)形成されている。これら2対の圧入部35,37は、それぞれの対が、図3の(b)に示すように、ピン端子15の幅方向Wに対して直交する高さ方向Hに沿って互いに異なる位置に、上記同様の鍛圧等によって突出して形成されている。本実施形態では、圧入部35が圧入部37よりも低い位置に配設されている。ピン端子15は、これら圧入部35,37が端子挿入孔19に圧入保持される。本実施形態において、圧入部35,37は、平面視で矩形状に形成されるが、挿入性が良好で、且つ端子挿入孔19からの抜脱が規制されるものであれば、その形状に限定されない。図示は省略するが、圧入部35,37は、例えば挿入方向先端側に、徐々に低くなる傾斜面を有するものであってもよい。圧入部35,37は、このような楔形状とすることで、挿入性を高めながら、保持性を確保することができる。   Each pin terminal 15 has a pair of press-fit portions 35 and press-fit portions 37 that protrude from both side edges in the width direction on the front end side in the insertion direction from the press-fit support portion 31 and are spaced apart along the insertion direction of the pin terminals. A plurality of pairs (two pairs in this embodiment) are formed. These two pairs of press-fitting portions 35 and 37 are located at different positions along the height direction H perpendicular to the width direction W of the pin terminal 15 as shown in FIG. The protrusion is formed by the same forging pressure as described above. In the present embodiment, the press-fit portion 35 is disposed at a position lower than the press-fit portion 37. In the pin terminal 15, these press-fit portions 35 and 37 are press-fitted and held in the terminal insertion holes 19. In the present embodiment, the press-fit portions 35 and 37 are formed in a rectangular shape in plan view, but are limited to the shape as long as the insertability is good and the removal from the terminal insertion hole 19 is restricted. Not. Although illustration is omitted, the press-fit portions 35 and 37 may have, for example, an inclined surface that gradually decreases on the distal end side in the insertion direction. The press-fitting portions 35 and 37 have such a wedge shape, so that the retainability can be ensured while improving the insertability.
図3の(a)に示すように、ピン端子15は、2対の圧入部35,37が高さ方向Hの異なる位置に設けられることで、コネクタハウジング17の端子挿入孔19に挿入される際に、挿入方向前方の圧入部37が先に圧入される。そして、挿入方向後方の圧入部35が圧入される際には、挿入方向前方の圧入部37と高さ方向Hに異なる位置で圧入される。このため、ピン端子15は、挿入方向後方の圧入部35が圧入される端子挿入孔19の圧入部分(両側壁)を挿入方向前方の圧入部37が削ることはない。これにより、ピン端子15は、挿入方向前方の圧入部37の圧入によって挿入方向後方の圧入部35の保持力に影響を与えることがなく、高い保持力が得られる。   As shown in FIG. 3A, the pin terminal 15 is inserted into the terminal insertion hole 19 of the connector housing 17 by providing two pairs of press-fit portions 35 and 37 at different positions in the height direction H. At this time, the press-fitting portion 37 in the insertion direction is first press-fitted. When the press-fitting part 35 at the rear in the insertion direction is press-fitted, it is press-fitted at a position different from the press-fitting part 37 at the front in the insertion direction in the height direction H. For this reason, in the pin terminal 15, the press-fitting portion 37 on the front side in the insertion direction does not cut the press-fitted portion (both side walls) of the terminal insertion hole 19 into which the press-fitting portion 35 on the rear side in the insertion direction is press-fitted. Thereby, the pin terminal 15 does not affect the holding force of the press-fitting part 35 at the rear in the insertion direction by the press-fitting of the press-fitting part 37 at the front in the insertion direction, and a high holding force is obtained.
また、ピン端子15は、一対の圧入支持部31同士の間またはその間の一部領域と、一対の圧入部同士の間またはその間の一部領域とにおける少なくとも一方に、非塑性加工面63が残されていることが好ましい。非塑性加工面63は、ピン端子15の端子表面61を塑性加工しない面となる。図示例では、非塑性加工面63は、複数対(2対)の圧入部35,37の間と、一対の圧入支持部31の間とに設けられる。なお、「その間の一部領域」とは、圧入支持部31同士の間の全て、圧入部35,37同士の間の全てに非塑性加工面63が設けられなくともよい意味である。換言すれば、非塑性加工面63は、圧入支持部31同士の間、圧入部35,37同士の間の一部領域をプレスにより押圧しないものであってもよい。   Further, the pin terminal 15 has a non-plastic working surface 63 remaining in at least one of a partial region between or between the pair of press-fit support portions 31 and a partial region between or between the pair of press-fit portions 31. It is preferable that The non-plastic working surface 63 is a surface on which the terminal surface 61 of the pin terminal 15 is not plastically processed. In the illustrated example, the non-plastic working surface 63 is provided between a plurality of pairs (two pairs) of press-fit portions 35 and 37 and between a pair of press-fit support portions 31. The “partial region therebetween” means that the non-plastic working surface 63 may not be provided in all between the press-fit support portions 31 and between the press-fit portions 35 and 37. In other words, the non-plastic working surface 63 may not press a partial region between the press-fit support portions 31 and between the press-fit portions 35 and 37 by pressing.
非塑性加工面63を設けたピン端子15によれば、圧入部35,37の近傍に非塑性加工面63が設けられることにより、圧入部35,37が形成されることによる強度の低下が抑制される。これにより、ピン端子15を挿入する際の端子変形が防止される。また、ピン端子15は、圧入支持部31の近傍に非塑性加工面63が設けられることにより、圧入支持部31が形成されることによる強度の低下が抑制される。これにより、ピン端子15は、圧入時に圧入支持部31を押した際の変形や破損が防止される。   According to the pin terminal 15 provided with the non-plastic working surface 63, the non-plastic working surface 63 is provided in the vicinity of the press-fitting portions 35 and 37, thereby suppressing a decrease in strength due to the formation of the press-fitting portions 35 and 37. Is done. Thereby, the terminal deformation | transformation at the time of inserting the pin terminal 15 is prevented. Further, the pin terminal 15 is provided with the non-plastic working surface 63 in the vicinity of the press-fit support portion 31, thereby suppressing a decrease in strength due to the press-fit support portion 31 being formed. Thereby, the pin terminal 15 is prevented from being deformed or damaged when the press-fit support portion 31 is pressed during press-fit.
更に、ピン端子15において、2対の圧入部35,37は、それぞれの対が、互いに異なる突出高さで形成されることにより、幅方向Wに異なる突出先端幅W1,W2を有してもよい。本実施形態においては、2対の圧入部35,37は、ピン端子15の挿入方向先端に近づくにしたがってそれぞれ突出高さが低くなるように形成されている(W1>W2)。つまり、挿入方向前方の一対の圧入部37は、その後ろの一対の圧入部35よりも突出高さが低くなっている。なお、圧入部35,37の突出高さは、本実施形態とは逆に圧入部37が、その後ろの一対の圧入部35よりも突出高さが高くてもよい。また、圧入部35,37は、同一の突出高さであってもよい。   Further, in the pin terminal 15, the two pairs of press-fit portions 35, 37 may have different projecting tip widths W 1, W 2 in the width direction W because the respective pairs are formed with different projecting heights. Good. In the present embodiment, the two pairs of press-fitting portions 35 and 37 are formed such that the protruding height decreases as approaching the distal end in the insertion direction of the pin terminal 15 (W1> W2). In other words, the pair of press-fit portions 37 at the front in the insertion direction has a lower protrusion height than the pair of press-fit portions 35 at the back. The protruding height of the press-fit portions 35 and 37 may be higher than the pair of press-fit portions 35 behind the press-fit portion 37, contrary to the present embodiment. Further, the press-fit portions 35 and 37 may have the same protruding height.
更に、ピン端子15は、予めメッキ処理が施された長尺の導電性の金属線材を所定長で切断して形成されることが好ましい。なお、本発明に係るピン端子は、予めメッキされた角線材をプレスして形成する場合に限らず、金属板を打ち抜き加工して形成したプレス端子であってもよい。本実施形態においては、ピン端子15は、予めメッキ処理が施された金属線材によって形成される。   Furthermore, it is preferable that the pin terminal 15 is formed by cutting a long conductive metal wire that has been plated in advance into a predetermined length. The pin terminal according to the present invention is not limited to a case where a pre-plated square wire is pressed and may be a press terminal formed by punching a metal plate. In the present embodiment, the pin terminal 15 is formed of a metal wire that has been plated in advance.
この場合、ピン端子15は、予めメッキ処理が施された長尺の導電性金属材料からなる金属線材を所定長さに切断することで形成されたものであるので、プレス加工で形成するピン端子を用いた場合と比較し、歩留りの向上を図ることができる。また、ピン端子15の電気接触部23にはメッキのない破断面が形成されないので、煩雑な後メッキ処理や面取りを行うことなく、良好な耐食性及び相手端子との良好な接続信頼性を確保することができ、高い品質を確保できる。
しかも、予めメッキした金属線材からなるピン端子15は、ダレやバリがなく、しかも、全周にわたってメッキが均一に施されている。そこで、コネクタハウジング17の端子挿入孔19がシール材により封止されるような場合には、ピン端子15の周囲におけるシール材との密着性を均一にすることができ、良好なシール性を確保できる。
In this case, the pin terminal 15 is formed by cutting a predetermined length of a metal wire made of a long conductive metal material that has been plated in advance. Yield can be improved as compared with the case of using. In addition, since an unplated fracture surface is not formed on the electrical contact portion 23 of the pin terminal 15, good corrosion resistance and good connection reliability with the counterpart terminal are ensured without performing complicated post-plating treatment or chamfering. Can ensure high quality.
Moreover, the pin terminal 15 made of a pre-plated metal wire is free from sagging and burrs, and is plated uniformly over the entire circumference. Therefore, when the terminal insertion hole 19 of the connector housing 17 is sealed with a sealing material, the adhesion with the sealing material around the pin terminal 15 can be made uniform, and a good sealing property is ensured. it can.
図4は同一位置(挿入方向先端から同じ位置)に圧入支持部31及び圧入部35,37が形成された長さの異なるピン端子15からなる端子群11の端子挿入位置を表す説明図である。
異なる長さのピン端子25,26,27,28,29,30は、ピン端子25の全長がL1、ピン端子26の全長がL2、ピン端子27の全長がL3、ピン端子28の全長がL4、ピン端子29の全長がL5、ピン端子30の全長がL6となる(L1<L2<L3<L4<L5<L6)。異なる長さのピン端子25,26,27,28,29,30は、端子挿入位置(端子先端)を揃えると、端子後端がずれる。この端子後端側は、プリント回路基板に対する上記の基板接続部21となる。また、端子先端側は、上記の電気接触部23となる。
FIG. 4 is an explanatory diagram showing the terminal insertion position of the terminal group 11 including the pin terminals 15 having different lengths in which the press-fit support portion 31 and the press-fit portions 35 and 37 are formed at the same position (the same position from the tip in the insertion direction). .
The pin terminals 25, 26, 27, 28, 29, and 30 having different lengths have a total length L1 of the pin terminal 25, a total length L2 of the pin terminal 26, a total length L3 of the pin terminal 27, and a total length L4 of the pin terminal 28. The total length of the pin terminal 29 is L5, and the total length of the pin terminal 30 is L6 (L1 <L2 <L3 <L4 <L5 <L6). The pin terminals 25, 26, 27, 28, 29, and 30 having different lengths are displaced from each other when the terminal insertion positions (terminal tips) are aligned. This terminal rear end side is the above-described board connecting portion 21 for the printed circuit board. Further, the terminal tip side is the electrical contact portion 23 described above.
ところで、端子後端を押してピン端子を端子保持穴に挿入する場合、ピン端子の長さが異なると、そのピン端子に合わせた挿入ストロークが必要となる。このため、挿入ヘッドが複数必要となる。   By the way, when the pin terminal is inserted into the terminal holding hole by pushing the rear end of the terminal, if the length of the pin terminal is different, an insertion stroke corresponding to the pin terminal is required. For this reason, a plurality of insertion heads are required.
一方、本実施形態に係る端子群11における長さの異なるピン端子25,26,27,28,29,30は、圧入部35,37及び圧入支持部31が、端子先端から同じ位置に形成されている。そこで、圧入支持部31の挿入方向後端側面33を押してコネクタハウジング17の端子挿入孔19に挿入する場合、長さが違うピン端子25,26,27,28,29,30であっても、全て同じ挿入ストロークSで挿入が可能となる。その結果、端子群11における複数のピン端子15は、一種類の挿入ヘッド39によって挿入が可能となる。   On the other hand, in the pin terminals 25, 26, 27, 28, 29, and 30 having different lengths in the terminal group 11 according to the present embodiment, the press-fit portions 35 and 37 and the press-fit support portion 31 are formed at the same position from the terminal tip. ing. Therefore, when the rear end side surface 33 in the insertion direction of the press-fit support portion 31 is pushed and inserted into the terminal insertion hole 19 of the connector housing 17, even if the pin terminals 25, 26, 27, 28, 29, and 30 have different lengths, All can be inserted with the same insertion stroke S. As a result, the plurality of pin terminals 15 in the terminal group 11 can be inserted by one type of insertion head 39.
また、ピン端子15の圧入部35,37は、圧入支持部31よりも挿入方向先端側に同一距離離れるように設定されている。そこで、異なる長さのピン端子25,26,27,28,29,305であっても、圧入支持部31を形成するためのプレス型と、圧入部35,37を形成するためのプレス型を同一位置に配置できる(勿論、1つのプレス型で圧入支持部31と圧入部35,37を同時に形成してもよい)。そこで、圧入支持部31及び圧入部35,37を形成する端子加工工程では、各種ピン端子15の長さに応じた供給ストロークで金属線材を圧入支持部31及び圧入部35,37のプレス型へ供給すればよく、端子加工工程へ供給する金属線材の供給量の制御が容易となる。   Further, the press-fit portions 35 and 37 of the pin terminal 15 are set so as to be separated from the press-fit support portion 31 by the same distance toward the distal end side in the insertion direction. Therefore, even for the pin terminals 25, 26, 27, 28, 29, and 305 having different lengths, a press die for forming the press-fit support portion 31 and a press die for forming the press-fit portions 35 and 37 are provided. They can be arranged at the same position (of course, the press-fit support portion 31 and the press-fit portions 35 and 37 may be formed simultaneously with one press die). Therefore, in the terminal processing step for forming the press-fit support portion 31 and the press-fit portions 35 and 37, the metal wire is transferred to the press die of the press-fit support portion 31 and the press-fit portions 35 and 37 with a supply stroke corresponding to the length of each pin terminal 15. What is necessary is just to supply, and control of the supply amount of the metal wire supplied to a terminal processing process becomes easy.
本実施形態に係る基板用コネクタ13は、図5に示すように、複数の端子挿入孔19を有するコネクタハウジング17と、上記の複数のピン端子15からなる端子群11とを備える。コネクタハウジング17は、絶縁性の合成樹脂材料からなり、所定の形状(例えば略直方体形状)に成形される。コネクタハウジング17には、ピン端子15を収容する複数の端子挿入孔19が横方向に一列に並んで形成されるとともに、これらの端子挿入孔19が上下に多段状に並ぶことで、多数の端子挿入孔19が縦横に配設される(図6参照)。本実施形態では、例えば複数列のピン端子15が6段に並ぶ例を図示するがこれに限定されない。   As shown in FIG. 5, the board connector 13 according to the present embodiment includes a connector housing 17 having a plurality of terminal insertion holes 19 and a terminal group 11 including the plurality of pin terminals 15. The connector housing 17 is made of an insulating synthetic resin material and is formed into a predetermined shape (for example, a substantially rectangular parallelepiped shape). In the connector housing 17, a plurality of terminal insertion holes 19 for receiving the pin terminals 15 are formed side by side in a row in the horizontal direction, and these terminal insertion holes 19 are arranged in multiple stages in the vertical direction so that a large number of terminals can be obtained. The insertion holes 19 are arranged vertically and horizontally (see FIG. 6). In the present embodiment, for example, an example in which a plurality of pin terminals 15 are arranged in six stages is illustrated, but the present invention is not limited to this.
次に、基板用コネクタ13の端子圧入方法を説明する。
図7の(a)は挿入ヘッド39によって保持される前のピン端子15の斜視図、(b)は挿入ヘッド39によって保持されたピン端子15の斜視図である。
ピン端子15をコネクタハウジング17に組み付けるには、先ず、図7に示すように、挿入ヘッド39(端子支持部41及び挟持部43)によってピン端子15が保持される。
Next, a terminal press-fitting method for the board connector 13 will be described.
7A is a perspective view of the pin terminal 15 before being held by the insertion head 39, and FIG. 7B is a perspective view of the pin terminal 15 held by the insertion head 39. FIG.
In order to assemble the pin terminal 15 to the connector housing 17, first, as shown in FIG. 7, the pin terminal 15 is held by the insertion head 39 (terminal support part 41 and clamping part 43).
端子支持部41と対向する挟持部43の下面には、端子支持部41との間に挟持したピン端子15に係合する係合溝45と、ピン端子15の圧入支持部31の挿入方向後端側面33を係止して後方移動を規制する一対の係止突部47とが、設けられている。これにより、挿入ヘッド39は、ピン端子15を保持し、端子切断装置(図示略)で所定長に切断されたピン端子15の挿入方向先端を、コネクタハウジング17の端子挿入孔19に対向させる。端子支持部41及び挟持部43は、圧入支持部31の挿入方向後端側面33を係止して、後方移動を規制した状態でピン端子15を保持する。   On the lower surface of the sandwiching portion 43 facing the terminal support portion 41, there is an engagement groove 45 that engages with the pin terminal 15 sandwiched between the terminal support portion 41 and the insertion direction of the press-fit support portion 31 of the pin terminal 15. A pair of locking projections 47 that lock the end side surface 33 and restrict rearward movement are provided. As a result, the insertion head 39 holds the pin terminal 15, and causes the distal end of the pin terminal 15 inserted in a predetermined length by a terminal cutting device (not shown) to face the terminal insertion hole 19 of the connector housing 17. The terminal support part 41 and the clamping part 43 hold | maintain the pin terminal 15 in the state which latched the insertion direction rear-end side surface 33 of the press-fit support part 31, and controlled back movement.
次いで、端子圧入装置におけるハウジング移動機構が、挿入ヘッド39に保持されたピン端子15が対応する端子挿入孔19にそれぞれ圧入されるように、コネクタハウジング17を挿入ストロークSの距離だけ移動する。   Next, the housing moving mechanism in the terminal press-fitting device moves the connector housing 17 by the distance of the insertion stroke S so that the pin terminals 15 held by the insertion head 39 are respectively press-fitted into the corresponding terminal insertion holes 19.
この際、挿入ヘッド39は、ピン端子15の異なる全長に係わらず挿入方向先端から同じ位置に形成された圧入支持部31を係止することができる。これにより、挿入ヘッド39は、コネクタハウジング17の端子挿入孔19へ挿入されるピン端子15の挿入反力を常に受けることができる。そのため、挿入ヘッド39とハウジング移動機構とは、異なる長さのピン端子25,26,27,28,29,30をコネクタハウジング17の複数の端子挿入孔19にそれぞれ、同一の挿入ストロークSによって連続挿入することができる。勿論、コネクタハウジング17に対して挿入ヘッド39を同一の挿入ストロークS前進させることで、異なる長さのピン端子25,26,27,28,29,30を複数の端子挿入孔19にそれぞれ挿入することもできる。   At this time, the insertion head 39 can lock the press-fit support portion 31 formed at the same position from the distal end in the insertion direction regardless of the different total lengths of the pin terminals 15. Thereby, the insertion head 39 can always receive the insertion reaction force of the pin terminal 15 inserted into the terminal insertion hole 19 of the connector housing 17. Therefore, the insertion head 39 and the housing moving mechanism are configured such that the pin terminals 25, 26, 27, 28, 29, and 30 having different lengths are continuously connected to the plurality of terminal insertion holes 19 of the connector housing 17 by the same insertion stroke S. Can be inserted. Of course, by moving the insertion head 39 forward with respect to the connector housing 17 by the same insertion stroke S, pin terminals 25, 26, 27, 28, 29, and 30 having different lengths are inserted into the plurality of terminal insertion holes 19, respectively. You can also.
また、これらピン端子15を形成するために所定長で切断される長尺の金属線材として、予めメッキ処理された長尺の金属線材を用いた場合、ピン端子15は圧入支持部31が挿入ヘッド39に係止されてコネクタハウジング17の端子挿入孔19へ挿入されるので、挿入ヘッド39がピン端子15の基板接続部21に接触することはなく、基板接続部21のメッキ剥がれが防止される。そこで、ピン端子15の基板接続部21がプリント回路基板の導電路に半田付けされる際のメッキ剥がれに伴う半田付け不良を防止できる。   When a long metal wire that has been plated in advance is used as a long metal wire that is cut at a predetermined length to form the pin terminals 15, the press-fit support portion 31 is inserted into the insertion head of the pin terminal 15. Since it is latched by 39 and inserted into the terminal insertion hole 19 of the connector housing 17, the insertion head 39 does not come into contact with the board connection portion 21 of the pin terminal 15, and the peeling of the plating of the board connection portion 21 is prevented. . Therefore, it is possible to prevent a soldering failure caused by peeling of the plating when the board connection portion 21 of the pin terminal 15 is soldered to the conductive path of the printed circuit board.
図8は端子挿入孔19にピン端子15が圧入された後のコネクタハウジング17の要部断面図である。
端子挿入孔19に挿入が完了したピン端子15は、圧入支持部31が端子挿入孔19の外側に配置される。つまり、ハウジング後端面49と圧入支持部31との間には、間隙が設けられる。この間隙は、干渉回避間隙51となる。圧入支持部31は、挿入ヘッド39で押圧された際、変形しても機能的には問題がない。そこで、基板用コネクタ13は、コネクタハウジング17と圧入支持部31との間に干渉回避間隙51を設けることにより、変形した圧入支持部31がコネクタハウジング17に当たることによる干渉が回避されるようになされている。即ち、端子挿入孔19に対するピン端子15の挿入位置は、圧入支持部31をコネクタハウジング17に当接させるのではなく、ハウジング移動機構による同一の挿入ストロークSによって正確に位置決めされる。そこで、圧入支持部31が当接したハウジング後端面49の変形などにより、ピン端子15の挿入位置がばらつくことはない。
FIG. 8 is a cross-sectional view of the main part of the connector housing 17 after the pin terminal 15 is press-fitted into the terminal insertion hole 19.
The pin terminal 15 that has been inserted into the terminal insertion hole 19 has a press-fit support portion 31 disposed outside the terminal insertion hole 19. That is, a gap is provided between the housing rear end surface 49 and the press-fit support portion 31. This gap becomes the interference avoidance gap 51. Even if the press-fit support portion 31 is deformed when pressed by the insertion head 39, there is no functional problem. Therefore, the board connector 13 is provided with an interference avoidance gap 51 between the connector housing 17 and the press-fit support portion 31 so that interference caused by the deformed press-fit support portion 31 hitting the connector housing 17 is avoided. ing. That is, the insertion position of the pin terminal 15 with respect to the terminal insertion hole 19 is accurately positioned by the same insertion stroke S by the housing moving mechanism, instead of bringing the press-fit support portion 31 into contact with the connector housing 17. Therefore, the insertion position of the pin terminal 15 does not vary due to deformation of the housing rear end surface 49 with which the press-fit support portion 31 abuts.
図9に示すように、ハウジング後端面49からは、異なる長さのピン端子25,26,27・・・が導出される。ピン端子25,26,27・・・は、長いものが外側(図9中、右側)となるように、それぞれの基板接続部21が、電気接触部23に対して直角に折り曲げられている。折り曲げられた基板接続部21は、図示しないプリント回路基板に対して垂直に配置される。この際、基板用コネクタ13は、端子挿入孔19から導出された直後の部分に、圧入支持部31が露出する。露出した圧入支持部31とハウジング後端面49との間には、上記の干渉回避間隙51が確保されている。   As shown in FIG. 9, pin terminals 25, 26, 27... Having different lengths are led out from the housing rear end surface 49. The pin terminals 25, 26, 27... Are each bent at a right angle with respect to the electrical contact portion 23 so that the long one is on the outside (right side in FIG. 9). The bent board connecting portion 21 is arranged perpendicular to a printed circuit board (not shown). At this time, in the board connector 13, the press-fit support portion 31 is exposed at a portion immediately after being led out from the terminal insertion hole 19. The interference avoidance gap 51 is secured between the exposed press-fit support portion 31 and the housing rear end surface 49.
次に、上記した構成の作用を説明する。
本実施形態に係るピン端子15では、コネクタハウジング17の端子挿入孔19にピン端子15が挿入される際には、先ず挿入方向前方の圧入部37が先に圧入される。そして、挿入方向後方の圧入部35が圧入される際には、挿入方向前方の圧入部37と高さ方向Hに異なる位置で圧入される。このため、ピン端子15は、挿入方向後方の圧入部35が圧入される端子挿入孔19の圧入部分(両側壁)を挿入方向前方の圧入部37が削ることはない。そこで、本実施形態のピン端子15は、挿入方向前方の圧入部37の圧入によって挿入方向後方の圧入部35の保持力に影響を与えることがなく、高い保持力が得られる。
Next, the operation of the above configuration will be described.
In the pin terminal 15 according to the present embodiment, when the pin terminal 15 is inserted into the terminal insertion hole 19 of the connector housing 17, first, the press-fit portion 37 at the front in the insertion direction is first press-fitted. When the press-fitting part 35 at the rear in the insertion direction is press-fitted, it is press-fitted at a position different from the press-fitting part 37 at the front in the insertion direction in the height direction H. For this reason, in the pin terminal 15, the press-fitting portion 37 on the front side in the insertion direction does not cut the press-fitted portion (both side walls) of the terminal insertion hole 19 into which the press-fitting portion 35 on the rear side in the insertion direction is press-fitted. Therefore, the pin terminal 15 of the present embodiment can obtain a high holding force without affecting the holding force of the press-fitting portion 35 at the rear of the insertion direction by the press-fitting of the press-fitting portion 37 at the front of the insertion direction.
また、図11に示した従来の圧入端子515は、幅方向W及び高さ方向Hに突出する複数の突起517,519を備えているため、突起517,519を形成する場合、角線材送り方向に対して上側及び横側から押圧しなければならず、圧入部形成用の設備が大型化する。これに対し、本実施形態のピン端子15では、ピン端子15の挿入方向前方の圧入部37と挿入方向後方の圧入部35とを同一のプレス型で(例えば上下側から)、プレスして形成できる。また、挿入方向前方の圧入部37を形成するためのプレス型と、挿入方向後方の圧入部35を形成するためのプレス型とが別体にされても、これらのプレス型を並列配置し、上下側から同時にプレスすればよい。   Further, since the conventional press-fit terminal 515 shown in FIG. 11 includes a plurality of protrusions 517 and 519 that protrude in the width direction W and the height direction H, when forming the protrusions 517 and 519, the square wire material feed direction On the other hand, it must be pressed from the upper side and the lateral side, and the equipment for forming the press-fit portion is enlarged. On the other hand, in the pin terminal 15 of the present embodiment, the press-fitting portion 37 in the insertion direction of the pin terminal 15 and the press-fitting portion 35 in the rear of the insertion direction are pressed by the same press die (for example, from the upper and lower sides). it can. Moreover, even if the press die for forming the press-fit portion 37 in the front in the insertion direction and the press die for forming the press-fit portion 35 in the rear in the insertion direction are separated, these press dies are arranged in parallel. What is necessary is just to press simultaneously from the upper and lower sides.
また、本実施形態のピン端子15では、挿入方向に沿った任意の位置における複数対の圧入部35,37の突出高さをそれぞれ変えることで、所望の一対の圧入部(圧入部35または圧入部37)の保持力を任意に設定することが可能となる。また、ピン端子15の圧入時の圧入抵抗と、その圧入によって得られる保持力とは一般的に比例するので、高い保持力を得ようとすれば、圧入抵抗が増大する。これを勘案し、例えば、2対の圧入部35,37は、ピン端子15の挿入方向先端に近づくにしたがってそれぞれ突出高さが低くなるように形成することができる。この場合、2対の圧入部35,37は、端子挿入孔19に挿入されるピン端子15の挿入深さが深くなるにしたがって、端子挿入孔19に対する圧接力が段階的に大きくなって端子挿入孔19の内面を徐々に変形させながら圧入されるので、挿入性が向上する。   Further, in the pin terminal 15 of the present embodiment, a desired pair of press-fitting parts (press-fitting part 35 or press-fitting part) can be obtained by changing the protruding heights of the plurality of pairs of press-fitting parts 35 and 37 at arbitrary positions along the insertion direction. It is possible to arbitrarily set the holding force of the portion 37). In addition, since the press-fitting resistance at the time of press-fitting the pin terminal 15 is generally proportional to the holding force obtained by the press-fitting, the press-fitting resistance increases if an attempt is made to obtain a high holding force. Taking this into consideration, for example, the two pairs of press-fitting portions 35 and 37 can be formed such that the protruding heights become lower as they approach the front end of the pin terminal 15 in the insertion direction. In this case, in the two pairs of press-fitting portions 35 and 37, as the insertion depth of the pin terminal 15 inserted into the terminal insertion hole 19 increases, the pressure contact force with respect to the terminal insertion hole 19 increases stepwise. Since the inner surface of the hole 19 is press-fitted while gradually deforming, the insertability is improved.
また、本実施形態に係る端子群11では、端子群11の複数のピン端子15がコネクタハウジング17の複数の端子挿入孔19にそれぞれ圧入される際には、複数のピン端子15の異なる全長に係わらず挿入方向先端から同じ位置に形成された圧入支持部31の挿入方向後端側面が挿入治具等に支持され、コネクタハウジング17の端子挿入孔19へ圧入されるピン端子15の圧入反力を常に受けることができる。そこで、長さの異なるピン端子15をコネクタハウジング17の複数の端子挿入孔19に同じ挿入ストロークSで連続挿入することができる。その結果、端子圧入装置を小型化でき、コネクタの製造コストを低減できる。また、本実施形態のピン端子15によれば、ピン端子15の挿入方向前方及び挿入方向後方の各圧入部37,35と、圧入支持部31とを同一のプレス型で(例えば上下側から)、プレスして形成できる。   Further, in the terminal group 11 according to this embodiment, when the plurality of pin terminals 15 of the terminal group 11 are respectively press-fitted into the plurality of terminal insertion holes 19 of the connector housing 17, the plurality of pin terminals 15 have different total lengths. Regardless, the insertion side rear end side surface of the press-fit support portion 31 formed at the same position from the front end of the insertion direction is supported by an insertion jig or the like, and the press-fit reaction force of the pin terminal 15 that is press-fitted into the terminal insertion hole 19 of the connector housing 17. Can always receive. Therefore, the pin terminals 15 having different lengths can be continuously inserted into the plurality of terminal insertion holes 19 of the connector housing 17 with the same insertion stroke S. As a result, the terminal press-fitting device can be reduced in size, and the manufacturing cost of the connector can be reduced. Further, according to the pin terminal 15 of the present embodiment, the press-fitting portions 37 and 35 in the insertion direction front and rear of the pin terminal 15 and the press-fitting support portion 31 are the same press die (for example, from the upper and lower sides). It can be formed by pressing.
更に、本実施形態の端子群11では、ピン端子15は、予めメッキ処理が施された長尺の導電性金属材料からなる金属線材を所定長さに切断することで形成されたものであるので、プレス加工で形成するピン端子を用いた場合と比較し、歩留りの向上を図ることができる。また、ピン端子15の電気接触部23にはメッキのない破断面が形成されないので、煩雑な後メッキ処理や面取りを行うことなく、良好な耐食性及び相手端子との良好な接続信頼性を確保することができ、高い品質を確保できる。
しかも、予めメッキした金属線材からなるピン端子15は、ダレやバリがなく、しかも、全周にわたってメッキが均一に施されている。そこで、コネクタハウジング17の端子挿入孔19がシール材により封止されるような場合には、ピン端子15の周囲におけるシール材との密着性を均一にすることができ、良好なシール性を確保できる。
Furthermore, in the terminal group 11 of this embodiment, the pin terminal 15 is formed by cutting a metal wire made of a long conductive metal material that has been plated in advance into a predetermined length. Compared with the case of using a pin terminal formed by press working, the yield can be improved. In addition, since an unplated fracture surface is not formed on the electrical contact portion 23 of the pin terminal 15, good corrosion resistance and good connection reliability with the counterpart terminal are ensured without performing complicated post-plating treatment or chamfering. Can ensure high quality.
Moreover, the pin terminal 15 made of a pre-plated metal wire is free from sagging and burrs, and is plated uniformly over the entire circumference. Therefore, when the terminal insertion hole 19 of the connector housing 17 is sealed with a sealing material, the adhesion with the sealing material around the pin terminal 15 can be made uniform, and a good sealing property is ensured. it can.
そして、本実施形態に係る基板用コネクタ13では、ピン端子15における挿入方向後方の圧入部35がコネクタハウジング17の端子挿入孔19に圧入される際には、後の圧入部35が、先の圧入部37と高さ方向の異なる位置で圧入される。このため、ピン端子15は、後の圧入部35の圧入される端子挿入孔19の圧入部分(両側壁)が削られることがない。   In the board connector 13 according to the present embodiment, when the press-fit portion 35 at the rear of the pin terminal 15 in the insertion direction is press-fitted into the terminal insertion hole 19 of the connector housing 17, the subsequent press-fit portion 35 is It press-fits at a position different from the press-fit portion 37 in the height direction. For this reason, in the pin terminal 15, the press-fitted portion (both side walls) of the terminal insertion hole 19 into which the subsequent press-fitting portion 35 is press-fitted is not cut.
そこで、本実施形態の基板用コネクタ13は、ピン端子15の挿入方向前方の圧入部37の圧入によって挿入方向後方の圧入部35の保持力が影響を受けることがなく、ピン端子15の保持力を向上させることができる。   Therefore, the board connector 13 of the present embodiment is not affected by the holding force of the press-fitting portion 35 at the rear of the insertion direction by the press-fitting of the press-fitting portion 37 at the front of the pin terminal 15 in the insertion direction. Can be improved.
したがって、本実施形態に係るピン端子15、端子群11及び基板用コネクタ13によれば、挿入方向前方の圧入部37の圧入によって挿入方向後方の圧入部35の保持力に影響を与えることがなく、ピン端子15の保持力を向上させることができる。   Therefore, according to the pin terminal 15, the terminal group 11, and the board connector 13 according to the present embodiment, the pressing force of the press-fit portion 37 on the front side in the insertion direction does not affect the holding force of the press-fit portion 35 on the rear side in the insertion direction. The holding force of the pin terminal 15 can be improved.
