本発明は、フラットケーブル（ＦＣ）を端子に接続する接続構造に関する。
The present invention relates to a connection structure for connecting a flat cable (FC) to a terminal.
フラットケーブルの接続構造が、特許文献１に提案されている。
A flat cable connection structure is proposed in Patent Document 1.
図１において、車室照明灯１１０にフラットケーブル１００の接続構造が適用されている。つまり、車室照明灯１１０内に、圧接端子部（図示せず）が設けられている。フラットケーブル１００は、間隔を置いて平行に配置された複数の導体１０１と、これらの導体１０１を被覆する絶縁性の被覆部１０２とを備える。導体１０１間の被覆部１０２の箇所には、スリット１０３がそれぞれ形成されている。このスリット１０３が形成された領域の導体１０１の箇所を圧接端子部に突き刺すことで、圧接端子部が導体１０１に圧接されている。

Slits 103 are respectively formed at portions of the covering portion 102 between the conductors 101. By piercing the location of the conductor 101 in the region where the slit 103 is formed into the pressure contact terminal portion, the pressure contact terminal portion is pressed against the conductor 101.
フラットケーブル１００の導体１０１間にスリット１０３が形成されているため、導体１０１間と圧接端子部間とのピッチずれを吸収することができ、フラットケーブル１００の接続信頼性を確保することができる。
Since the slit 103 is formed between the conductors 101 of the flat cable 100, it is possible to absorb a pitch shift between the conductors 101 and between the press contact terminals, and to ensure the connection reliability of the flat cable 100.
ところで、フラットケーブル１００にスリット１０３を形成する工程を、車室照明灯１１０への組み付け工程前に別工程として行う必要があるため、手間が掛かる。又、スリット形成は、専用の高価な加工設備が必要である。
By the way, since it is necessary to perform the process of forming the slit 103 in the flat cable 100 as a separate process before the assembly process to the vehicle interior illumination lamp 110, it takes time and effort. In addition, the slit formation requires dedicated and expensive processing equipment.
本発明は、フラットケーブルにスリットを設けるための前工程及び専用の高価なスリット加工設備を要せずに、フラットケーブルにスリット加工を施すことができるフラットケーブルの接続構造を提供することを目的とする。

また、前記スリットは、前記圧接端子部が前記複数の導体の対応する導体に圧接する領域を含む範囲に形成されていてもよい。
Further, the slit may be formed in a range including a region where the pressure contact terminal portion is in pressure contact with a corresponding conductor of the plurality of conductors.
また、前記切断刃は、前記ホルダにインサート成形により形成されてもよい。
The cutting blade may be formed on the holder by insert molding.
上記構成によれば、ホルダのフラットケーブル挿入室にフラットケーブルを挿入すると、フラットケーブル挿入室に突出する切断刃によりフラットケーブルが切り込まれるので、フラットケーブルにスリットが形成される。従って、フラットケーブルにスリットを設けるための前工程及び専用の高価なスリット加工設備を要せずに、フラットケーブルにスリット加工を施すことができ、費用の低減を図ることができる。また、フラットケーブルの挿入前には、フラットケーブルの端末が切り込まれておらず、バラけていないため、フラットケーブルのホルダへの組付けを容易に行うことができる。
According to the above configuration, when the flat cable is inserted into the flat cable insertion chamber of the holder, the flat cable is cut by the cutting blade protruding into the flat cable insertion chamber, so that a slit is formed in the flat cable. Therefore, slitting can be performed on the flat cable without requiring a pre-process for providing a slit in the flat cable and a dedicated expensive slit processing facility, thereby reducing costs. Further, before the flat cable is inserted, the end of the flat cable is not cut and is not loosened, so that the flat cable can be easily assembled to the holder.

Since the second holder 9 has the same configuration as the first holder 5, description thereof is omitted.
次に、コネクタ１の組み立作業を説明する。まず、図１１に示すように、第１ホルダ５に後方からフラットケーブル挿入室５１に第１フラットケーブル４を挿入する。この挿入過程で、第１ホルダ５のフラットケーブル挿入室５１に突出する切断刃５２により第１フラットケーブル４が切り込まれるので、第１フラットケーブル４の端末にスリット４３が形成される（図１０参照）。
Next, the assembly work of the connector 1 will be described. First, as shown in FIG. 11, the first flat cable 4 is inserted into the flat cable insertion chamber 51 from the rear in the first holder 5. In this insertion process, since the first flat cable 4 is cut by the cutting blade 52 protruding into the flat cable insertion chamber 51 of the first holder 5, a slit 43 is formed at the end of the first flat cable 4 (FIG. 10). reference).
次いで、図１２に示すように、第１ホルダ５をロアハウジング２上に装着する。すると、図１３に示すように、第１ホルダ５で保持される第１フラットケーブル４を備えたロアハウジング２となる。この装着過程で、第１ホルダ５により、第１フラットケーブル４が複数の第１端子３に対して圧接されるので、各圧接端子部３３は、被覆部４２を貫通して導体４１に食い込むことにより電気的に接触する。
Next, as shown in FIG. 12, the first holder 5 is mounted on the lower housing 2. Then, as shown in FIG. 13, the lower housing 2 including the first flat cable 4 held by the first holder 5 is obtained. In this mounting process, the first flat cable 4 is pressed against the plurality of first terminals 3 by the first holder 5, so that each press contact terminal portion 33 penetrates the covering portion 42 and bites into the conductor 41. To make electrical contact.
次いで、図１４に示すように、ロアハウジング２上にアッパハウジング６を装着する。すると、図１５に示すように、一体化したロアハウジング２及びアッパハウジング６となる。その後、図１６に示すように、アッパハウジング６上に第２フラットケーブル８付きの第２ホルダ９を装着する。この装着過程で、第２フラットケーブル８の第２ホルダ９への挿入により、フラットケーブル挿入室９１に突出する切断刃（図示せず）で第２フラットケーブル８が切り込まれるので、第２フラットケーブル８の端末にスリット８３が形成される（図１０参照）。また、第２ホルダ９のアッパハウジング６への装着により、第２フラットケーブル８が複数の第２端子７に対して圧接されるので、圧接端子部７３は、被覆部８２を貫通して導体８１に食い込むことにより電気的に接触する。
Next, as shown in FIG. 14, the upper housing 6 is mounted on the lower housing 2. Then, as shown in FIG. 15, an integrated lower housing 2 and upper housing 6 are obtained.

上記組立過程にあって、圧接端子部３３，７３に第１及び第２フラットケーブル４，８が圧接される際に、各導体４１，８１がスリット４４，８４によって幅方向に独立して変移できる。このため、第１及び第２端子３，７の圧接端子部３３，７３間と第１及び第２フラットケーブル４，８の導体４１，８１間とのピッチずれを吸収でき、適正な電気的接続状態を得ることができる。
In the above assembly process, when the first and second flat cables 4 and 8 are pressed against the press contact terminals 33 and 73, the conductors 41 and 81 can be independently shifted in the width direction by the slits 44 and 84. . For this reason, it is possible to absorb a pitch shift between the press contact terminal portions 33 and 73 of the first and second terminals 3 and 7 and between the conductors 41 and 81 of the first and second flat cables 4 and 8, and to make an appropriate electrical connection. The state can be obtained.

As described above, the first and second holders 5 and 9 protrude into the flat cable insertion chambers 51 and 91 and the flat cable insertion chambers 51 and 91 into which the first and second flat cables 4 and 8 are inserted. A cutting blade 52 is provided, and the cutting blade 52 forms slits 43 and 83 in the first and second flat cables 4 and 8 inserted into the flat cable insertion chambers 51 and 91. Therefore, the first and second flat cables 4 and 8 can be inserted without requiring a pre-process for providing the slits 43 and 83 in the first and second flat cables 4 and 8 and a dedicated expensive slit processing facility. Slit processing can be performed in the process, and cost can be reduced. Further, before the first and second flat cables 4 and 8 are inserted, the terminals of the first and second flat cables 4 and 8 are not cut and are not separated. For this reason, the first and second flat cables 4 and 8 can be easily assembled to the first and second holders 5 and 9.
被覆部４２の切り込み（スリット４３）は、第１端子３の圧接端子部３３が導体４１に圧接する領域を含む範囲に形成されている。従って、圧接端子部３３間のピッチと導体４１間のピッチとのずれを確実に吸収でき、圧接端子部３３に導体４１を確実に圧接して適正な電気的接続ができる。同様に、被覆部８２の切り込み（スリット８３）は、第２端子７の圧接端子部７３が導体８１に圧接する領域を含む範囲に形成されている。従って、第２端子７の圧接端子部７３間のピッチと導体８１間のピッチとのずれを確実に吸収でき、圧接端子部７３に導体８１を確実に圧接して適正な電気的接続ができる。
The notch (slit 43) of the covering portion 42 is formed in a range including a region where the pressure contact terminal portion 33 of the first terminal 3 is in pressure contact with the conductor 41. Accordingly, the deviation between the pitch between the press contact terminal portions 33 and the pitch between the conductors 41 can be reliably absorbed, and the conductor 41 can be reliably pressed into contact with the press contact terminal portion 33 so that proper electrical connection can be made. Similarly, the notch (slit 83) of the covering portion 82 is formed in a range including a region where the pressure contact terminal portion 73 of the second terminal 7 is in pressure contact with the conductor 81. Therefore, the deviation between the pitch between the press contact terminal portions 73 of the second terminal 7 and the pitch between the conductors 81 can be reliably absorbed, and the conductor 81 can be reliably pressed into contact with the press contact terminal portion 73 to achieve an appropriate electrical connection.
切断刃５２が第１ホルダ５のフラットケーブル挿入室５１内にインサート成形されるので、比較的安価に切断刃５２を設けることができる。同様に、切断刃が第２ホルダ９のフラットケーブル挿入室９１内にインサート成形されるので、比較的安価に切断刃を設けることができる。
Since the cutting blade 52 is insert-molded in the flat cable insertion chamber 51 of the first holder 5, the cutting blade 52 can be provided relatively inexpensively. Similarly, since the cutting blade is insert-molded in the flat cable insertion chamber 91 of the second holder 9, the cutting blade can be provided relatively inexpensively.
また、本実施形態では、第１及び第２フラットケーブル４、８の接続構造がコネクタ１に適用されているが、これに限定されるものではない。例えば、フラットケーブル４、８を車載搭載機器（車室照明機器等）に接続する接続構造に適用しても良い。
In the present embodiment, the connection structure of the first and second flat cables 4 and 8 is applied to the connector 1, but the present invention is not limited to this. For example, you may apply to the connection structure which connects the flat cables 4 and 8 to vehicle equipment (vehicle interior lighting apparatus etc.).
このように、本発明は、ここでは記載していない様々な実施の形態などを含むことは勿論である。したがって、本発明の技術的範囲は、上述の説明から妥当な請求の範囲に係る発明特定事項によってのみ定められる。
Thus, it goes without saying that the present invention includes various embodiments that are not described herein. Therefore, the technical scope of the present invention is determined only by the invention specifying matters according to the scope of claims reasonable from the above description.
