Description

本発明は、電線に接続する電気コネクタ及び電気コネクタの製造方法に関する。   The present invention relates to an electrical connector connected to an electric wire and a method for manufacturing the electrical connector.

従来、高周波信号を伝送するために高周波対応の電線に接続される電気コネクタが知られている。このような電気コネクタは、電線の特性インピーダンスと整合されていない場合には高周波信号の反射による伝送効率の低下及びノイズの発生等の不具合を生じるので、このような不具合を抑制するために、特性インピーダンスの整合（マッチング）を図る必要がある。   2. Description of the Related Art Conventionally, an electrical connector connected to a high-frequency compatible electric wire for transmitting a high-frequency signal is known. When such an electrical connector is not matched with the characteristic impedance of the electric wire, it causes problems such as a decrease in transmission efficiency due to reflection of high-frequency signals and generation of noise. It is necessary to match the impedance (matching).

特許文献１は、高周波対応の電線の信号線が端子の圧着部に圧着されて接続する電気コネクタを開示している。このような従来の電気コネクタの信号線を圧着後の圧着部は、信号線との電気的な接続信頼性を優先するために信号線に強固に圧着されることに伴って、端子の圧着部以外の部分よりも小径になる。このような圧着部の特性インピーダンスは、電線の特性インピーダンスに比べて高くなって電線の特性インピーダンスと不整合となる。これにより、高周波信号の反射による伝送効率の低下及びノイズの発生等の不具合を生じる。   Patent Document 1 discloses an electrical connector in which a signal line of a high-frequency compatible electric wire is crimped and connected to a crimping portion of a terminal. The crimping part after crimping the signal line of such a conventional electrical connector is firmly crimped to the signal line in order to give priority to the reliability of electrical connection with the signal line. Smaller than other parts. The characteristic impedance of such a crimping part becomes higher than the characteristic impedance of the electric wire and becomes inconsistent with the characteristic impedance of the electric wire. As a result, problems such as a decrease in transmission efficiency due to reflection of high-frequency signals and generation of noise occur.

これに対して、従来の電気コネクタは、筒状の金属製スリーブを更に圧着部の上から圧着して圧着部側を大径にすることにより、特性インピーダンスの不整合を解消している。   On the other hand, the conventional electrical connector eliminates the mismatch of characteristic impedance by further crimping the cylindrical metal sleeve from above the crimping part to increase the diameter of the crimping part side.

特開２００３−１６３０５８号公報JP 2003-163058 A

しかしながら、従来の電気コネクタにおいては、筒状の金属製スリーブを更に圧着部の上から圧着する場合に、金属製スリーブと圧着部との電気的な接続信頼性を得られるように、金属製スリーブと圧着部とを強固に圧着する必要があるため、端子の圧着部を塑性変形させてしまう可能性がある。これにより、電線と端子との接続信頼性が低下し、極端な場合には電線が端子の圧着部から脱落してしまうという課題を有する。   However, in the conventional electrical connector, when the cylindrical metal sleeve is further crimped from above the crimping portion, the metal sleeve is provided so that the electrical connection reliability between the metal sleeve and the crimping portion can be obtained. Therefore, there is a possibility that the crimping portion of the terminal is plastically deformed. Thereby, the connection reliability of an electric wire and a terminal falls, and it has the subject that an electric wire will fall from the crimping | compression-bonding part of a terminal in an extreme case.

本発明の目的は、良好な電気的特性を得ることができると共に、端子部材と信号線との接続部に悪影響を与える負荷を取り除くことにより端子部材と信号線との安定した接触を実現することができる電気コネクタを提供することである。   An object of the present invention is to achieve good electrical characteristics and realize stable contact between a terminal member and a signal line by removing a load that adversely affects the connection portion between the terminal member and the signal line.

A conductive terminal member accommodated in the housing, and provided around the outer peripheral surface of the rear connection portion, and is locked to the housing by an elastic force and elastic to the rear connection portion. And a connecting member having conductivity that comes into contact.

本発明に係る電気コネクタの製造方法は、電線に接続する電気コネクタの製造方法であって、接続相手と接続する前方接続部と後方接続部とを備える導電性を有する端子部材の前記後方接続部に前記電線の信号線を接続する工程と、前記後方接続部に前記信号線を接続した前記端子部材を、絶縁性を有するハウジングに収容する工程と、弾性変形可能な導電性を有する接続部材を、前記ハウジングに収容された前記端子部材の前記後方接続部に弾性接触させると共に前記ハウジングに係止させて、前記前方接続部よりも小径の前記後方接続部の外周面の周囲に前記接続部材を設ける工程と、を有する。   A method for manufacturing an electrical connector according to the present invention is a method for manufacturing an electrical connector connected to an electric wire, wherein the rear connection portion of a terminal member having conductivity includes a front connection portion and a rear connection portion connected to a connection partner. A step of connecting the signal line of the electric wire, a step of housing the terminal member having the signal line connected to the rear connection portion in an insulating housing, and an electrically conductive connecting member capable of elastic deformation. The connection member is elastically brought into contact with the rear connection portion of the terminal member accommodated in the housing and locked to the housing, and the connection member is disposed around the outer peripheral surface of the rear connection portion having a smaller diameter than the front connection portion. Providing.

後方接続部に信号線を接続した際における後方接続部と後方接続部に接続する接続部材とにより構成される部分の径を、後方接続部の径よりも大径にして、特性インピーダンスの整合を図ると共に、接続部材が後方接続部の外周面に弾性接触することにより、後方接続部に対して信号線との接続に悪影響を及ぼす負荷が加わらない。   Match the characteristic impedance by making the diameter of the part composed of the rear connection part and the connection member connected to the rear connection part when the signal line is connected to the rear connection part larger than the diameter of the rear connection part. In addition, since the connecting member elastically contacts the outer peripheral surface of the rear connection portion, a load that adversely affects the connection with the signal line is not applied to the rear connection portion.

本発明によれば、良好な電気的特性を得ることができると共に、端子部材と信号線との接続部に悪影響を与える負荷を取り除くことにより端子部材と信号線との安定した接触を実現することができる。   According to the present invention, good electrical characteristics can be obtained, and stable contact between the terminal member and the signal line can be realized by removing a load that adversely affects the connection portion between the terminal member and the signal line. Can do.

＜電気コネクタの製造方法＞
本発明の実施形態に係る電気コネクタ１の製造方法につき、以下に詳細に説明する。 <Manufacturing method of electrical connector>
The manufacturing method of the electrical connector 1 according to the embodiment of the present invention will be described in detail below.

まず、端子部材５０の後方接続部５２の貫通孔５２１に対して電線１００の各芯線１０２の中心導体１０２ａを挿通した状態で、後方接続部５２を圧着することにより後方接続部５２に中心導体１０２ａを固定して中心導体１０２ａと端子部材５０とを接続する。   First, in a state where the central conductor 102a of each core wire 102 of the electric wire 100 is inserted into the through hole 521 of the rear connection portion 52 of the terminal member 50, the rear connection portion 52 is crimped to the central conductor 102a to the rear connection portion 52. And the center conductor 102a and the terminal member 50 are connected.

次に、中心導体１０２ａを接続した端子部材５０を端子ガイド部材４０のガイド溝４１に収容して、係止部５４を前方幅広部４１１の段差部４１３に係止すると共に係止部５５を前方幅広部４１１の段差部４１４に係止し、更に後方接続部５２を後方幅広部４１２に収容して図５に示す状態にする。   Next, the terminal member 50 connected to the central conductor 102a is accommodated in the guide groove 41 of the terminal guide member 40, and the locking portion 54 is locked to the stepped portion 413 of the front wide portion 411 and the locking portion 55 is moved to the front. 5 is engaged with the stepped portion 414 of the wide portion 411, and the rear connecting portion 52 is accommodated in the rear wide portion 412 so that the state shown in FIG.

次に、後方幅広部４１２とクリップ部材６０とを位置合わせした後に、クリップ部材６０の押圧部６１４の突出方向の先端部を図示しない冶具等で突出方向と反対方向（図４において下方）に押圧することにより、クリップ部材６０を後方幅広部４１２内に収容していく。この際に、クリップ部材６０の突出部６１２等の押圧部６１４以外を押圧せずに押圧部６１４を押圧することにより、クリップ部材６０の変形を防ぐことができるため電気コネクタ１の電気的性能の低下を防ぐことができる。また、後方から見て中心導体１０２ａの中心を通るｙ−ｚ平面と平行な仮想線に対して、左右対称となるように一対設けられた突出部６１２を、この仮想線に沿って押圧するため、後方幅広部４１２に対してクリップ部材６０が斜めに収容されないようにすることができる。   Next, after aligning the rear wide portion 412 and the clip member 60, the tip end portion of the pressing portion 614 of the clip member 60 is pressed in a direction opposite to the protruding direction (downward in FIG. 4) with a jig or the like (not shown). By doing so, the clip member 60 is accommodated in the rear wide portion 412. At this time, since the deformation of the clip member 60 can be prevented by pressing the pressing portion 614 without pressing other than the pressing portion 614 such as the protruding portion 612 of the clip member 60, the electrical performance of the electrical connector 1 can be prevented. Decline can be prevented. Further, in order to press the protrusions 612 provided in a pair so as to be symmetric with respect to a virtual line parallel to the yz plane passing through the center of the central conductor 102a when viewed from the rear, along the virtual line. The clip member 60 can be prevented from being accommodated obliquely with respect to the rear wide portion 412.

次に、当接接続部６１３が後方接続部５２に当接するまで後方幅広部４１２に対するクリップ部材６０の収容を継続して、挟持片６１の内部に後方接続部５２を収容することにより、クリップ部材６０の挟持片６１が後方接続部５２に押圧されて左右に拡径すると共に、挟持片６１の弾性復帰力により挟持片６１が後方接続部５２に弾性接触する。また、係止片６２の係止部６２３が後方幅広部４１２の内壁により押圧されて延設部６２１及び延設部６２２が内方に弾性変形すると共に、係止片６２の係止部６２３が後方幅広部４１２の内壁に係止されることにより、端子部材５０及びクリップ部材６０を端子ガイド部材４０に仮固定した図３に示す状態になる。   Next, the clip member 60 is continuously accommodated in the rear wide portion 412 until the abutting connection portion 613 abuts on the rear connection portion 52, and the rear connection portion 52 is accommodated inside the holding piece 61, thereby the clip member. The clamping piece 61 of 60 is pressed by the rear connection portion 52 to increase the diameter to the left and right, and the clamping piece 61 is brought into elastic contact with the rear connection portion 52 by the elastic restoring force of the clamping piece 61. Further, the locking portion 623 of the locking piece 62 is pressed by the inner wall of the rear wide portion 412 so that the extending portion 621 and the extending portion 622 are elastically deformed inward, and the locking portion 623 of the locking piece 62 is By being locked to the inner wall of the rear wide portion 412, the terminal member 50 and the clip member 60 are temporarily fixed to the terminal guide member 40 as shown in FIG. 3.

これにより、クリップ部材６０を後方接続部５２に圧着して接続させることなく弾性接続させることにより、中心導体１０２ａと後方接続部５２との安定した接続を得ることができると共に接続性能や圧着強度を劣化させないようにすることができ、加工設備を簡単にすることができるため製造コストを低減することができる。また、クリップ部材６０に後方接続部５２を収容する際のストッパ部と、クリップ部材６０と後方接続部５２とを電気的に接続する接続部と、を当接接続部６１３で兼用することにより、クリップ部材６０を簡易な構成にすることができ、製品コスト又は製造コストを低減することができる。   As a result, the clip member 60 is elastically connected to the rear connection portion 52 without being crimped and connected, so that a stable connection between the central conductor 102a and the rear connection portion 52 can be obtained, and connection performance and pressure strength can be improved. It can be prevented from deteriorating and the manufacturing cost can be reduced because the processing equipment can be simplified. Further, by combining the stopper portion when the rear connection portion 52 is accommodated in the clip member 60 and the connection portion that electrically connects the clip member 60 and the rear connection portion 52 with the contact connection portion 613, The clip member 60 can have a simple configuration, and the product cost or manufacturing cost can be reduced.

また、図３に示す仮固定した状態において、図４に示すように、後方接続部５２の全体を挟持片６１の内部に収容することにより、弾性接続部６１１と先端６１ａとの距離を長くすることができるため、クリップ部材６０が浮き上がって後方幅広部４１２から脱落してしまうことを確実に防ぐことができる。また、挟持片６１を後方接続部５２の全体を内部に収容できる長さにすることにより、先端６１ａから係止部６２３までの長さを長くすることができることにより、後方幅広部４１２内に係止部６２３を係止させる際の弾性力を大きくすることができるため、係止部６２３を後方幅広部４１２内に確実に係止させることができる。   Further, in the temporarily fixed state shown in FIG. 3, as shown in FIG. 4, the distance between the elastic connecting portion 611 and the distal end 61 a is increased by accommodating the entire rear connecting portion 52 inside the clamping piece 61. Therefore, it is possible to reliably prevent the clip member 60 from floating and dropping off from the rear wide portion 412. Further, by making the holding piece 61 long enough to accommodate the entirety of the rear connection portion 52, the length from the tip 61a to the locking portion 623 can be increased, so that the inside of the rear wide portion 412 is engaged. Since the elastic force at the time of locking the locking portion 623 can be increased, the locking portion 623 can be reliably locked in the rear wide portion 412.

次に、端子部材５０及びクリップ部材６０を仮固定した端子ガイド部材４０を内部絶縁部材３０に挿入すると共に、端子ガイド部材４０の係合突起４２を内部絶縁部材３０の図示しない係合孔に係合することにより、端子ガイド部材４０を内部絶縁部材３０に固定する。これにより、内部絶縁部材３０に仮固定された端子部材５０及びクリップ部材６０は、ガイド溝４１が内部絶縁部材３０の内壁によって塞がれることにより、内部絶縁部材３０から脱落することなく内部絶縁部材３０に収容される。   Next, the terminal guide member 40 temporarily fixed with the terminal member 50 and the clip member 60 is inserted into the internal insulating member 30, and the engaging protrusion 42 of the terminal guide member 40 is engaged with the engaging hole (not shown) of the internal insulating member 30. By joining, the terminal guide member 40 is fixed to the internal insulating member 30. As a result, the terminal member 50 and the clip member 60 temporarily fixed to the internal insulating member 30 are prevented from dropping from the internal insulating member 30 when the guide groove 41 is blocked by the inner wall of the internal insulating member 30. 30.

次に、端子ガイド部材４０を固定した内部絶縁部材３０を、外部絶縁部材２０に挿入して図示しない固定機構によって外部絶縁部材２０に固定する。   Next, the internal insulating member 30 to which the terminal guide member 40 is fixed is inserted into the external insulating member 20 and fixed to the external insulating member 20 by a fixing mechanism (not shown).

次に、外部絶縁部材２０の外表面を覆うようにシールドケース１０を取り付けることにより、電気コネクタ１の製造及び組み立てを終了する。   Next, the shield case 10 is attached so as to cover the outer surface of the external insulating member 20, thereby completing the manufacture and assembly of the electrical connector 1.
