Description

本発明は、自動車等に搭載される各種機器の電気接続に使用される端子構造に係り、特に、コネクタハウジングの端子保持壁に圧入保持される角線材を使用した基板用コネクタの端子保持構造に関する。   The present invention relates to a terminal structure used for electrical connection of various devices mounted on an automobile or the like, and more particularly, to a terminal holding structure for a board connector using a square wire that is press-fitted and held on a terminal holding wall of a connector housing. .

従来、角線材を使用した基板用の端子をコネクタハウジングの端子保持壁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に記載のものは、コネクタハウジングの端子保持壁に貫通して設けられた複数の端子保持穴に圧入保持され、角線材から成形される基板用の端子構造において、前記端子保持穴に保持される基板用端子の係止部の横方向に前記端子保持穴の両側壁に圧入されるように形成された一対の第１の係止突起を設けるとともに、前記端子保持穴に保持される前記基板用端子の前記係止部の縦方向に前記端子保持穴の少なくとも天壁または底壁に圧入されるように形成された第２の係止突起を設けたものである。   2. Description of the Related Art Conventionally, various types of terminal holding structures in the case of press-fitting and holding board terminals using square wires on terminal holding walls of a connector housing are known. For example, the one described in Patent Document 1 is a terminal structure for a board that is press-fitted and held in a plurality of terminal holding holes provided so as to penetrate through a terminal holding wall of a connector housing and is molded from a rectangular wire. A pair of first locking projections formed so as to be press-fitted into both side walls of the terminal holding hole are provided in the lateral direction of the locking portion of the board terminal held by the terminal, and are held in the terminal holding hole.

特開２０００−２４３４９５号公報（「０００７、０００８」、図４）JP 2000-243495 A (“0007, 0008”, FIG. 4)

上記特許文献１に記載の角線材を使用した基板用コネクタにおいて、端子のハウジングへの保持は、コネクタハウジングの端子保持壁に形成された端子保持穴への端子の圧入と端子の第１、第２の係止突起（ダボ）により保たれている。圧入量が大きく、保持が確実になるが、一方、圧入量が大きいために端子をハウジングに挿入する際の負荷が大きく、端子挿入スピードが低下するのが避けられない。また、端子の形状が複雑となり、正確な成形が困難である。端子挿入スピード低下の対策として端子保持穴を広げることが有効であるが、端子保持穴を広げた分、端子保持力が低下する。   In the board connector using the square wire described in Patent Document 1, the terminal is held in the housing by press-fitting the terminal into the terminal holding hole formed in the terminal holding wall of the connector housing and the first and second terminals. It is held by two locking projections (doughs). The press-fitting amount is large and the holding is ensured. On the other hand, since the press-fitting amount is large, a load when inserting the terminal into the housing is large, and it is inevitable that the terminal insertion speed decreases. Further, the shape of the terminal is complicated, and accurate molding is difficult. Although it is effective to widen the terminal holding hole as a countermeasure against a decrease in the terminal insertion speed, the terminal holding force is reduced as the terminal holding hole is widened.

本発明の課題は、端子保持力を低下させることなく、簡易な構造で端子を確実に保持することができる基板用コネクタの端子保持構造を提供することである。   The subject of this invention is providing the terminal holding structure of the connector for board | substrates which can hold | maintain a terminal reliably with a simple structure, without reducing a terminal holding force.

上記課題は、端子保持壁を備えたコネクタハウジングと、前記端子保持壁に貫通して設けられた端子保持穴に圧入され、前記端子保持穴に係止部で保持される基板用端子と、を含んでなる基板用コネクタの端子保持構造であって、前記基板用端子の係止部を、前記基板用端子１の横方向に前記端子保持穴の両側壁に圧入されるように形成された一対の後部係止突起と、前記後部係止突起の端子圧入方向後方に前記端子保持穴の両側壁に圧入されるように形成された一対の前部係止突起とを含んで構成し、前記後部係止突起と前部係止突起を異なる形状に形成した基板用コネクタの端子保持構造により、達成される。   The above-described problem includes a connector housing having a terminal holding wall, and a board terminal that is press-fitted into a terminal holding hole provided through the terminal holding wall and held in the terminal holding hole by a locking portion. The board connector terminal holding structure includes a pair of board terminal locking portions that are press-fitted into both side walls of the terminal holding hole in the lateral direction of the board terminal 1. A rear locking projection and a pair of front locking projections formed so as to be press-fitted into both side walls of the terminal holding hole at the rear of the rear locking projection in the terminal press-fitting direction. This is achieved by the terminal holding structure of the board connector in which the locking protrusion and the front locking protrusion are formed in different shapes.

上記構成において、前部係止突起を側壁高さ方向に測った寸法Ｘは後部係止突起を側壁高さ方向に測った寸法Ｘ’よりも小さく、前部係止突起を端子保持穴底壁幅方向に測った寸法Ｙは後部係止突起を端子保持穴底壁幅方向に測った寸法Ｙ’よりも大きくした形状とするのが望ましい。   In the above configuration, the dimension X of the front locking projection measured in the side wall height direction is smaller than the dimension X ′ of the rear locking projection measured in the side wall height direction. The dimension Y measured in the width direction is desirably a shape in which the rear locking projection is larger than the dimension Y ′ measured in the terminal holding hole bottom wall width direction.

また、前記後部係止突起と前部係止突起の形状は、基板用端子圧入時に端子保持穴の側壁に対向する面に、谷底線が基板用端子の長手方向軸線と平行な、断面Ｖ形の溝を備えたものであることが望ましい。   Further, the shape of the rear locking projection and the front locking projection is such that the valley line is parallel to the longitudinal axis of the board terminal, and has a V-shaped cross section on the surface facing the side wall of the terminal holding hole when the board terminal is pressed. It is desirable to have a groove.

本発明によれば、簡易な形状で成形加工が容易になるとともに、前部と後部の係止突起の形状が異なるため、それぞれの係止突起が効果的に端子保持壁に食い込み、ハウジングに対し高い端子保持効果が得られる。また、上下左右方向に対する端子の振れも抑制される。   According to the present invention, the molding process is easy with a simple shape, and the shapes of the front and rear locking protrusions are different, so that each locking protrusion effectively bites into the terminal holding wall and against the housing. A high terminal holding effect is obtained. Moreover, the terminal shake with respect to the vertical and horizontal directions is also suppressed.

以下、本発明の基板用コネクタの端子保持構造に係る実施の形態を、図面を参照して説明する。本発明の実施の形態に係る、基板用コネクタの端子保持構造における角線材を使用した基板用端子１は、図６に示したコネクタハウジング２の端子保持壁３に設けられた複数の端子保持穴４に圧入保持される。図１に示すように、本実施の形態の基板用端子１は、前部（端子圧入方向後方になる部分）に前部電気接触部１ａが形成されて相手コネクタの電気接触部と電気的に接続される。また後部（端子圧入方向前方になる部分）に後部電気接続部１ｂが形成されていて、コネクタハウジング２の背面に装着された基板８の回路パターン側に貫通してはんだ付けされる。端子保持穴４は側壁５、天壁６、底壁７で囲まれた矩形断面をなしており、角線材を使用して形成された基板用端子１が圧入されるようになっている。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the terminal holding structure for a board connector of the present invention will be described below with reference to the drawings. The board terminal 1 using the rectangular wire in the board connector terminal holding structure according to the embodiment of the present invention has a plurality of terminal holding holes provided in the terminal holding wall 3 of the connector housing 2 shown in FIG. 4 is press-fitted and held. As shown in FIG. 1, the board terminal 1 according to the present embodiment has a front electrical contact portion 1a formed in a front portion (a portion that is rearward in the terminal press-fitting direction) and is electrically connected to the electrical contact portion of the mating connector. Connected. Further, a rear electrical connection portion 1b is formed at the rear portion (portion that is forward in the terminal press-fitting direction), and is penetrated and soldered to the circuit pattern side of the substrate 8 mounted on the back surface of the connector housing 2. The terminal holding hole 4 has a rectangular cross section surrounded by the side wall 5, the top wall 6 and the bottom wall 7, and the board terminal 1 formed using a square wire is press-fitted therein.

基板用端子１の前記前部電気接触部１ａと後部電気接続部１ｂの中間部には、端子保持穴４に保持される係止部が設けられ、この係止部は、前記後部電気接続部１ｂ側に配置された後部係止突起１ｄと、前記前部電気接触部１ａ側、すなわち後部係止突起１ｄの基板用端子１の圧入方向後方側に配置された前部係止突起１ｃと、で構成されている。前部係止突起１ｃは、図１のＡ−Ａ’断面である図２に示されているように、基板用端子１の横方向の両側部に互いに対称な形状で方形に突出した突出部をなし、その外方の端部には、谷底線が基板用端子１の長手方向軸線と平行な断面Ｖ形の溝が形成されている。後部係止突起１ｄも、図１のＢ−Ｂ’断面である図３に示されているように、基板用端子１の横方向の両側部に互いに対称な形状で方形に突出した突出部をなし、その外方の端部には、谷底線が基板用端子１の長手方向軸線と平行な断面Ｖ形の溝が形成されている。   At the intermediate portion of the front electrical contact portion 1a and the rear electrical connection portion 1b of the board terminal 1, there is provided a latching portion held in the terminal holding hole 4, and this latching portion is the rear electrical connection portion. A rear locking projection 1d disposed on the 1b side, a front locking projection 1c disposed on the front electrical contact portion 1a side, that is, on the rear side in the press-fitting direction of the board terminal 1 of the rear locking projection 1d, It consists of As shown in FIG. 2, which is a cross section taken along the line AA ′ of FIG. 1, the front portion locking protrusion 1 c is a protrusion that protrudes in a square shape in a symmetrical manner on both sides in the lateral direction of the board terminal 1 A groove having a V-shaped cross section in which the valley bottom line is parallel to the longitudinal axis of the board terminal 1 is formed at the outer end. As shown in FIG. 3 which is a BB ′ cross section of FIG. 1, the rear locking protrusion 1d is also provided with protrusions protruding in a square shape with symmetrical shapes on both lateral sides of the board terminal 1. None, a groove having a V-shaped cross section is formed at the outer end thereof, with the valley line parallel to the longitudinal axis of the board terminal 1.

前部係止突起１ｃと後部係止突起１ｄは、その突出部の図２、図３における図上、上下方向の寸法（基板用端子１が端子保持穴４に圧入されたとき、側壁５に食い込む部分を側壁高さ方向に測った寸法）をそれぞれＸ，Ｘ’としたとき、Ｘ＜Ｘ’であり、その突出部の図２、図３における図上、横方向の寸法（一方の突出部の外側端から他方の突出部の外側端までの寸法）をそれぞれＹ，Ｙ’としたとき、Ｙ＞Ｙ’である点が異なっている。   The front locking projection 1c and the rear locking projection 1d are vertically dimensioned in FIG. 2 and FIG. 3 of the protruding portion (when the board terminal 1 is press-fitted into the terminal holding hole 4, the side wall 5 When X and X ′ are the dimensions measured in the side wall height direction of the biting portion, respectively, X <X ′, and the horizontal dimension (one protrusion) of the protrusions in FIGS. Y> Y ′, where Y and Y ′ are the dimensions from the outer end of the portion to the outer end of the other protruding portion, respectively.

また、端子保持穴４の側壁高さをＸ０とすると、Ｘ０＞Ｘ’であることはいうまでもなく、端子保持穴４の底壁幅（天壁幅）をＹ０とすると、Ｙ０＜Ｙ’であって、基板用端子１が端子保持穴４に圧入されたとき、前部係止突起１ｃと後部係止突起１ｄは、いずれも、外方側先端部が端子保持穴４の側壁５に食い込んで基板用端子１を端子保持壁３に保持する。 If the side wall height of the terminal holding hole 4 is X 0 , it goes without saying that X 0 > X ′, and if the bottom wall width (top wall width) of the terminal holding hole 4 is Y 0 , When 0 <Y ′ and the board terminal 1 is press-fitted into the terminal holding hole 4, both the front locking projection 1 c and the rear locking projection 1 d have the outer tip at the terminal holding hole 4. The board terminal 1 is held on the terminal holding wall 3 by biting into the side wall 5.

図４に、基板用端子１の係止部の斜視図を示す。また、図５は、コネクタハウジング２の端子保持壁３に形成された端子保持穴４の部分破砕斜視図である。基板用端子１は端子保持穴４に圧入されると、先に述べたように、Ｙ０＜Ｙ’＜Ｙであることから、その後部係止突起１ｄが側壁５の表面に近い位置で広い範囲に食い込むとともに、その前部係止突起１ｃが範囲は狭いが側壁５の表面から深い位置まで端子保持壁３に食い込み、それぞれが効果的に締まり嵌めになって基板用端子１をコネクタハウジング２に保持する。 FIG. 4 is a perspective view of the locking portion of the board terminal 1. FIG. 5 is a partially broken perspective view of the terminal holding hole 4 formed in the terminal holding wall 3 of the connector housing 2. When the board terminal 1 is press-fitted into the terminal holding hole 4, as described above, since Y 0 <Y ′ <Y, the rear locking projection 1 d is wide at a position close to the surface of the side wall 5. The front locking protrusion 1c bites into the range, but the range is narrow, but bites into the terminal holding wall 3 from the surface of the side wall 5 to a deep position. Hold on.

なお、上記実施の形態において、前部係止突起１ｃと後部係止突起１ｄの形状を互いに入れ替えても、同様の効果が得られる。圧入方向の同一線上に２箇所の係止突起が配置された基板用端子が端子保持穴４の側壁５に圧入されるとき、２箇所の係止突起が側壁に対して同じ位置に同じ断面形状で形成されていると、先行する後部係止突起１ｄにより端子保持穴４の側壁５が塑性変形され、この塑性変形された側壁面に後続する前部係止突起が圧入されるため、前部係止突起による側壁への係止力が不足する恐れがある。しかし、上記実施の形態では、前部係止突起１ｃと後部係止突起１ｄの形状が異なるため、上述の恐れが解消される。   In the above embodiment, the same effect can be obtained even if the shapes of the front locking projection 1c and the rear locking projection 1d are interchanged. When a board terminal having two locking projections arranged on the same line in the press-fitting direction is press-fitted into the side wall 5 of the terminal holding hole 4, the two locking projections have the same cross-sectional shape at the same position with respect to the side wall. In this case, the side wall 5 of the terminal holding hole 4 is plastically deformed by the preceding rear locking protrusion 1d, and the front locking protrusion subsequent to the plastically deformed side wall surface is press-fitted. There is a possibility that the locking force to the side wall by the locking protrusion is insufficient. However, in the said embodiment, since the shape of the front part latching protrusion 1c and the rear part latching protrusion 1d differs, the above-mentioned fear is eliminated.

本実施の形態によれば、係止部が簡易な形状なので基板用端子の成形加工が容易になる。また、前部係止突起１ｃと後部係止突起１ｄは、異なる形状、大きさで突起しているので、端子圧入の際に前部係止突起１ｃと後部係止突起１ｄは、互いに異なる部位の端子保持壁３に食い込み保持するから、コネクタハウジングに対し高い端子保持効果が得られるとともに、端子の上下左右方向に対する端子の振れも抑制する効果がある。   According to the present embodiment, since the locking portion has a simple shape, it is easy to mold the board terminal. Further, since the front locking protrusion 1c and the rear locking protrusion 1d protrude in different shapes and sizes, the front locking protrusion 1c and the rear locking protrusion 1d are different from each other when the terminals are press-fitted. The terminal holding wall 3 is bitten and held, so that a high terminal holding effect is obtained with respect to the connector housing, and there is an effect that the terminal is prevented from swinging in the vertical and horizontal directions.
