Description

GEBIET DER ERFINDUNGFIELD OF THE INVENTION

Die vorliegende Erfindung betrifft eine Verbindungsstruktur zur Verbindung mehrerer Verbinder und einen mittels der Verbindungsstruktur mit einem anderen Verbinder verbundenen Verbinder.The present invention relates to a connection structure for connecting a plurality of connectors and a connector connected to another connector by means of the connection structure.

TECHNISCHER HINTERGRUNDTECHNICAL BACKGROUND

Eine große Anzahl von Signalkabeln ist mit verschiedenen Arten von sich bewegenden Körpern, einschließlich Kraftfahrzeugen, verdrahtet. Verbindungsstrukturen zum Zusammenfügen der Signalkabel untereinander und/oder zum Zusammenfügen eines Signalkabels und einer Leiterplatte sind in der Technik bekannt. JP 2015-93650 A beschreibt eine Verbindungsstruktur für einen in einem Fahrzeug verwendeten Verbinder.A large number of signal cables are wired to various types of moving bodies including automobiles. Connection structures for joining the signal cables together and / or for joining a signal cable and a circuit board are known in the art. JP 2015-93650 A describes a connection structure for a connector used in a vehicle.

Eine Verbindungsstruktur, in der ein erstes und zweites Steckverbinder-Gehäuse über eine sogenannte Primärrastverbindung miteinander verbunden sind, geht jeweils der US 2017/0040741 A1 , der US 5,910,027 A und der EP 2 637 260 A1 hervor. Die Primärrastverbindung setzt sich jeweils aus einem elastischen Arretierungsbügel, der an einem Steckverbinder-Gehäuse ausgebildet ist, und einer am anderen Steckverbinder-Gehäuse ausgebildeten Öffnung zusammen, in die der Arretierungsbügel eingreift. In jeder dieser drei Druckschriften wir die Primärrastverbindung zwischen den beiden Steckverbinder-Gehäusen jeweils über ein Verriegelungsglied gesichert.A connection structure in which a first and second connector housing are connected to one another via what is known as a primary latching connection is provided by the US 2017/0040741 A1 , the U.S. 5,910,027 A and the EP 2 637 260 A1 emerged. The primary latching connection is composed in each case of an elastic locking clip, which is formed on one connector housing, and an opening formed on the other connector housing, into which the locking clip engages. In each of these three publications, the primary locking connection between the two connector housings is secured by a locking member.

Zum Lösen einer Primärrastverbindung zwischen zwei Steckverbinder-Gehäusen offenbaren die DE 198 58 467 A1 und die US 5,672,071 A jeweils einen EingriffsfreigabeAbschnitt, der separat zum Arretierungsbügel am Steckverbinder-Gehäuse ausgebildet ist und den Arretierungsbügel aus der Öffnung am anderen Steckverbinder-Gehäuse löst.To release a primary snap connection between two connector housings, the disclose DE 198 58 467 A1 and the U.S. 5,672,071 A an engagement release section, which is separate from the locking bracket on the Connector housing is formed and releases the locking bracket from the opening on the other connector housing.

KURZFASSUNG DER ERFINDUNGSUMMARY OF THE INVENTION [Durch die Erfindung zu lösendes Problem][Problem to be Solved by the Invention]

Ein in einem sich bewegenden Körper verwendeter Verbinder muss sehr zuverlässig sein. Bei einer herkömmlichen Verbindungsstruktur werden ein Verbinderstecker und eine Verbinderbuchse jedoch einfach zusammengefügt, so dass, wenn die beiden Verbinder bei der Herstellung nicht ordnungsgemäß zusammengefügt werden oder ein Verbindergehäuse beschädigt ist, insofern ein Problem entsteht, als die Gefahr besteht, dass sich die Verbinder aufgrund von der Bewegung des sich bewegenden Körpers begleitenden Erschütterungen lösen können. Ferner besteht die Gefahr hinsichtlich des gleichen Problems, das bei Verbindern entsteht, die in anderen Vorrichtungen als sich bewegenden Körpern verwendet werden, wenn die Verbinder während der Herstellung nicht ordnungsgemäß zusammengefügt werden.A connector used in a moving body must be very reliable. In a conventional connection structure, however, a connector plug and a connector socket are simply mated, so that if the two connectors are not mated properly during manufacture or a connector housing is damaged, a problem arises that the connectors are likely to become disconnected due to solve the vibrations accompanying the movement of the moving body. There is also a danger of the same problem that arises with connectors used in devices other than moving bodies if the connectors are not properly mated during manufacture.

Deshalb ist die vorliegende Erfindung angesichts der obigen Aspekte konzipiert worden, und ihr Ziel besteht darin, einen Zustand, in dem mehrere Verbinder sicher zusammengefügt sind, leicht aufrechtzuerhalten.Therefore, the present invention has been made in view of the above aspects, and its aim is to easily maintain a state in which a plurality of connectors are securely fitted together.

[Mittel zum Lösen des Problems][Means to solve the problem]

Eine Verbindungsstruktur gemäß der vorliegenden Erfindung ist eine Struktur gemäß Anspruch 1.A connection structure according to the present invention is a structure according to claim 1.

Das Verriegelungsglied kann sich in einem Zustand, in dem der erste Verbindungsanschluss und der zweite Verbindungsanschluss zusammengefügt sind, bis zu der vorbestimmten Position auf der Seite des ersten Verbinders bewegen und kann sich in einem Zustand, in dem der erste Verbindungsanschluss und der zweite Verbindungsanschluss nicht zusammengefügt sind, nicht zu der vorbestimmten Position bewegen.The locking member can move to the predetermined position on the first connector side in a state in which the first connection terminal and the second connection terminal are mated, and can move in a state in which the first connection terminal and the second connection terminal are not mated do not move to the predetermined position.

Bei Anlegen der äußeren Kraft an den Eingriffsfreigabeabschnitt in einem Zustand, in dem das Verriegelungsglied nicht zu der Seite des ersten Verbinders eingeschoben ist, kann sich der Eingriffsfreigabeabschnitt dahingehend verformen, die Belastung anzulegen, die dazu erforderlich ist, den Eingriffsabschnitt zu einem Zustand zu verformen, in dem er aus der Öffnung ausgerückt werden kann, und bei Anlegen der äußeren Kraft an den Eingriffsfreigabeabschnitt in einem Zustand, in dem das Verriegelungsglied zu der Seite des ersten Verbinders eingeschoben ist, kann sich der Eingriffsfreigabeabschnitt dahingehend verformen, eine geringere Belastung als die Belastung, die dazu erforderlich ist, dass sich der Eingriffsabschnitt zu einem Zustand verformt, in dem er aus der Öffnung ausgerückt werden kann, anzulegen.When the external force is applied to the engagement release portion in a state in which the locking member is not pushed in to the side of the first connector, the engagement release portion may deform to apply the load necessary to deform the engagement portion to a state in which it can be disengaged from the opening, and when the external force is applied to the engagement release portion in a state in which the locking member is pushed in to the side of the first connector, the engagement release portion may deform to the effect that a load less than the load which is required for the engaging portion to deform to a state in which it can be disengaged from the opening to apply.

Der erste Verbinder 1 umfasst einen ersten Verbindungsanschluss 10, ein erstes Gehäuse 11, eine Öffnung 12 und eine Kabelverbindung 13. Der erste Verbindungsanschluss 10 ist ein Anschlussstecker, der zum Beispiel mit einer Anschlussbuchse (unten als zweiter Verbindungsanschluss 20 bezeichnet) des zweiten Verbinders 2 verbunden ist. Der erste Verbindungsanschluss 10 umfasst mehrere (in Figur 2(b) vier) Verbindungsstifte.The first connector 1 comprises a first connection terminal 10, a first housing 11, an opening 12 and a cable connection 13. The first connection terminal 10 is a connector plug which is connected to a connection socket (hereinafter referred to as second connection terminal 20) of the second connector 2, for example is. The first Connection port 10 comprises several (in Figure 2 (b) four) connecting pins.

Das erste Gehäuse 11 ist ein um den ersten Verbindungsanschluss 10 herum vorgesehenes Harzglied. Wie in Figur 2(b) gezeigt wird, sind eine Öffnung 111L und eine Öffnung 111R in dem ersten Gehäuse 11 ausgebildet.The first housing 11 is a resin member provided around the first connection terminal 10. As in Figure 2 (b) As shown, an opening 111L and an opening 111R are formed in the first housing 11.

Ferner ist eine Öffnung 112 zwischen der Öffnung 111L und der Öffnung 111R in dem ersten Gehäuse 11 ausgebildet, und mindestens eine Öffnung 12 ist über der Öffnung 112 ausgebildet. Die Öffnung 12 ist ein Bereich, in den ein Eingriffsabschnitt 22 des später zu beschreibenden zweiten Verbinders 2 eingeführt wird. Die Öffnung 12 ist an einer Außenumfangsfläche eines zylindrischen Bereichs des ersten Gehäuses 11, die mit mindestens einem Teil des zweiten Verbinders 2 in Berührung kommt, ausgebildet. In dem in Figur 2(a) gezeigten Beispiel ist die Öffnung 12 an einer Seitenfläche auf einer Oberseite des ersten Gehäuses 11 ausgebildet.Further, an opening 112 is formed between the opening 111L and the opening 111R in the first housing 11, and at least one opening 12 is formed over the opening 112. The opening 12 is a region into which an engaging portion 22 of the second connector 2 to be described later is inserted. The opening 12 is formed on an outer peripheral surface of a cylindrical portion of the first housing 11 that comes into contact with at least a part of the second connector 2. In the in Figure 2 (a) In the example shown, the opening 12 is formed on a side surface on an upper side of the first housing 11.

Die Kabelverbindung 13 umfasst eine Öffnung, die das Einführen eines Kabels in den ersten Verbinder 1 ermöglicht, und einen Verbinder zur Verbindung des Kabels.The cable connection 13 comprises an opening which enables a cable to be inserted into the first connector 1, and a connector for connecting the cable.

Der zweite Verbinder 2 umfasst einen zweiten Verbindungsanschluss 20, ein zweites Gehäuse 21, einen Eingriffsabschnitt 22, einen Eingriffsfreigabeabschnitt 23, ein Verriegelungsglied 24 und eine Kabelverbindung 25. Der zweite Verbindungsanschluss 20 ist eine Anschlussbuchse, die zum Beispiel mit einem Anschlussstecker (einem ersten Verbindungsanschluss 10) des ersten Verbinders 1 verbunden ist. Der zweite Verbindungsanschluss 20 umfasst mehrere (in Figur 3(b) vier) Verbindungsstifte.The second connector 2 includes a second connection terminal 20, a second housing 21, an engagement portion 22, an engagement release portion 23, a locking member 24 and a cable connection 25. The second connection terminal 20 is a female connector connected to, for example, a connector plug (a first connection terminal 10 ) of the first connector 1 is connected. The second connection terminal 20 comprises several (in Figure 3 (b) four) connecting pins.

Das zweite Gehäuse 21 ist ein um den zweiten Verbindungsanschluss 20 herum vorgesehenes Harzglied. Der Eingriffsabschnitt 22 und der Eingriffsfreigabeabschnitt 23 sind zum Beispiel am zweiten Gehäuse 1 vorgesehen. Der Eingriffsabschnitt 22 und der Eingriffsfreigabeabschnitt 23 können integral mit dem zweiten Gehäuse 1 geformt sein, oder sie können getrennt von dem zweiten Gehäuse 21 geformt und dann an dem zweiten Gehäuse 21 befestigt sein.The second housing 21 is a resin member provided around the second connection terminal 20. The engagement portion 22 and the engagement release portion 23 are provided on the second housing 1, for example. The engaging portion 22 and the engaging release portion 23 may be molded integrally with the second housing 1, or they may be molded separately from the second housing 21 and then fixed to the second housing 21.

Der Eingriffsabschnitt 22 ist ein Teil, das in einem Zustand, in dem der erste Verbindungsanschluss 10 und der zweite Verbindungsanschluss 20 zusammengefügt sind und das zweite Gehäuse 21 mit dem ersten Gehäuse 11 zusammengefügt ist, mit der in dem ersten Gehäuse 11 ausgebildeten Öffnung 12 in Eingriff steht. Der Eingriffsabschnitt 22 ist an einer Fläche nahe einem Endabschnitt des zweiten Gehäuses 21 auf einer Seite, die mit dem ersten Verbinder 1 zusammengefügt wird, fixiert. Der Eingriffsabschnitt 22 ist ein langes Teil, das an einer Außenumfangsfläche eines den zweiten Verbindungsanschluss 20 umgebenden zylindrischen Bereichs des zweiten Gehäuses 21 befestigt ist, und erstreckt sich von dem Endabschnitt des zweiten Gehäuses 21 weg. Der Eingriffsabschnitt 22 ist mit einer solchen Dicke ausgebildet, dass er sich infolge einer daran angelegten äußeren Kraft in einer Vertikalrichtung biegen kann und verformt, um nach Einführen in die Öffnung 12 einen Zustand einzunehmen, in dem er mit der Öffnung 12 in Eingriff steht, und einen Zustand einzunehmen, der die Freigabe des Eingriffs mit der Öffnung 12 ermöglicht.The engaging portion 22 is a part that engages with the opening 12 formed in the first housing 11 in a state where the first connection terminal 10 and the second connection terminal 20 are fitted together and the second housing 21 is fitted with the first housing 11 stands. The engaging portion 22 is fixed to a surface near an end portion of the second housing 21 on a side that is mated with the first connector 1. The engaging portion 22 is a long piece attached to an outer peripheral surface of a cylindrical portion of the second housing 21 surrounding the second connection terminal 20, and extends away from the end portion of the second housing 21. The engaging portion 22 is formed with such a thickness that it can bend and deform in a vertical direction due to an external force applied thereto to be in a state of being engaged with the opening 12 after being inserted into the opening 12, and assume a state that enables the release of engagement with the opening 12.

Wie in Figur 3 und Figur 4 gezeigt wird, umfasst der Eingriffsabschnitt 22 eine Auskragung 221, eine Aussparung 222, einen herunterzudrückenden Abschnitt 223 und einen offenen Abschnitt 224. Die Auskragung 221 wird in die Öffnung 12 eingeführt und gelangt mit einer Innenfläche der Öffnung 12 in Eingriff. Die Auskragung 221 umfasst eine schräge Fläche, die mit zunehmender Entfernung von dem Endabschnitt des zweiten Verbinders 2 auf der Seite des ersten Verbinders 1 höher wird, und eine senkrechte Endfläche, die von der höchsten Stelle der schrägen Fläche ausgeht. Die Endfläche bildet einen Absatz D, und wenn ein Benutzer den zweiten Verbinder 2 in Richtung des ersten Verbinders 1 einschiebt, verformt sich der Eingriffsabschnitt 22 mit höher werdender Position der schrägen Fläche der mit dem Endabschnitt des ersten Gehäuses 11 in Berührung stehenden Auskragung 221 nach unten, und der Eingriffsabschnitt 22 verschiebt sich zu dem Zeitpunkt, zu dem der Absatz D in die Öffnung 12 eintritt, nach oben. In diesem Zustand nimmt der Absatz D die Innenfläche der Öffnung 12 in Eingriff, wodurch der zweite Verbinder 2 einen mit dem ersten Verbinder 1 zusammengefügten Zustand einnimmt.As in Figure 3 and Figure 4 As shown, the engaging portion 22 includes a protrusion 221, a recess 222, a depressing portion 223, and an open portion 224. The protrusion 221 is inserted into the opening 12 and engages an inner surface of the opening 12. The cantilever 221 includes an inclined surface that becomes higher as the distance from the end portion of the second connector 2 increases on the first connector 1 side, and a vertical end surface that extends from the highest point of the inclined surface. The end surface forms a shoulder D, and when a user pushes the second connector 2 toward the first connector 1, the engaging portion 22 deforms downward as the position of the inclined surface of the projection 221 in contact with the end portion of the first housing 11 becomes higher , and the engaging portion 22 slides upward at the time the step D enters the opening 12. In this state, the shoulder D engages the inner surface of the opening 12, whereby the second connector 2 assumes a state of being fitted with the first connector 1.

Die Aussparung 222 ist ein Teil, in dem ein Spitzenende des Verriegelungsglieds 24 in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, eingeführt ist. Die Aussparung 222 ist bezüglich der Seite, auf der die Auskragung 221 ausgebildet ist, auf der gegenüberliegenden Seite des Eingriffsabschnitts 22 ausgebildet. Die Aussparung 222 ist zum Beispiel ein Raum zwischen einem langen Harzglied, an dem die Auskragung 221 ausgebildet ist, und der Außenumfangsfläche des den zweiten Verbindungsanschluss 20 umgebenden zylindrischen Bereichs des zweiten Gehäuses 21. Die Aussparung 222 kann durch das Harzglied, an dem die Auskragung 221 ausgebildet ist, gebildet werden.The recess 222 is a part in which a tip end of the locking member 24 is inserted in a state where the locking member 24 is pushed to the first connector 1 side. The recess 222 is formed on the opposite side of the engaging portion 22 with respect to the side on which the projection 221 is formed. The recess 222 is, for example, a space between a long resin member on which the projection 221 is formed and the outer peripheral surface of the cylindrical portion of the second housing 21 surrounding the second connection terminal 20. The recess 222 can pass through the resin member on which the projection 221 is formed, are formed.

Der herunterzudrückende Abschnitt 223 ist ein plattenförmiges Teil, an das von dem Eingriffsfreigabeabschnitt 23 eine äußere Abwärtskraft angelegt wird, wenn ein Benutzer den Eingriffsfreigabeabschnitt 23 nach unten drückt, und erstreckt sich zu dem hinteren Ende des Absatzes D. Der herunterzudrückende Abschnitt 223 kann breiter als die Auskragung 221 sein, und die Auskragung 221 kann an dem herunterzudrückenden Abschnitt 223 ausgebildet sein. An den herunterzudrückenden Abschnitt 223 wird infolgedessen, dass der Eingriffsfreigabeabschnitt 23 nach unten geschoben wird, eine Abwärtsbelastung angelegt, so dass sich das die Auskragung 221 enthaltende lange Harzglied biegt und sich die Auskragung 221 nach unten bewegt. In diesem Zustand legt ein Benutzer eine Kraft in eine Richtung zum Zurückziehen des zweiten Verbinders 2 aus dem ersten Verbinder 1 an, wodurch die Zusammenfügung des ersten Verbinders 1 und des zweiten Verbinders 2 gelöst wird.The depressing portion 223 is a plate-shaped member to which an external downward force is applied from the engaging release portion 23 when a user pushes the engaging release portion 23 downward, and extends to the rear end of the step D. The Depressing portion 223 may be wider than the protrusion 221, and the protrusion 221 may be formed on the depressing portion 223. A downward load is applied to the depressing portion 223 as a result of the engaging release portion 23 being pushed down, so that the long resin member including the projection 221 bends and the projection 221 moves downward. In this state, a user applies a force in a direction to withdraw the second connector 2 from the first connector 1, thereby disconnecting the first connector 1 and the second connector 2.

Wie in Figur 4(b) gezeigt wird, ist der offene Abschnitt 224 ein nahe der Mitte des herunterzudrückenden Abschnitts 223 ausgebildetes Langloch. Ein einen Spitzenendabschnitt des Verriegelungsglieds 24 enthaltender Teilbereich wird in den offenen Abschnitt 224 eingeführt, wenn ein Benutzer den Eingriffsfreigabeabschnitt 23 nach unten drückt. Der detaillierte Vorgang, der bewirkt wird, wenn der Benutzer den Eingriffsfreigabeabschnitt 23 nach unten drückt, wird später beschrieben.As in Figure 4 (b) As shown, the open portion 224 is an elongated hole formed near the center of the depressed portion 223. A portion including a tip end portion of the locking member 24 is inserted into the open portion 224 when a user pushes the engagement release portion 23 downward. The detailed operation effected when the user pushes down the engagement release portion 23 will be described later.

Der Eingriffsfreigabeabschnitt 23 ist zum Beispiel ein Teil, an das von einem Benutzer eine äußere Kraft angelegt wird, wodurch an den Eingriffsabschnitt 22 eine Belastung angelegt wird, derart, dass sich der Eingriffsabschnitt 22 zu einem Zustand verformt, in dem er aus der Öffnung ausgerückt werden kann. Wie in Figur 3(b) und Figur 4(a) gezeigt wird, umfasst der Querschnitt des Eingriffsfreigabeabschnitt 23 in einer orthogonal zur Längsrichtung der Verbindungsstruktur S verlaufenden Richtung einen rechteckigen Bereich, der an einer Seite dahingehend offen ist, einen später zu beschreibenden stangenförmigen Abschnitt 241 des Verriegelungsglieds 24 zu umschließen. Ein Plattenabschnitt 231 zum Anlegen einer Belastung an den herunterzudrückenden Abschnitt 223, wenn eine äußere Kraft den Eingriffsfreigabeabschnitt 23 nach unten drückt, ist auf der linken Seite und der rechten Seite des offenen Bereichs ausgebildet.The engagement release portion 23 is, for example, a part to which an external force is applied by a user, whereby a load is applied to the engagement portion 22 such that the engagement portion 22 deforms to a state of being disengaged from the opening can. As in Figure 3 (b) and Figure 4 (a) As shown, the cross section of the engagement release portion 23 in a direction orthogonal to the longitudinal direction of the connecting structure S comprises a rectangular area which is open on one side to enclose a rod-shaped portion 241 of the locking member 24 to be described later. A plate section 231 to lay on a load on the portion to be depressed 223 when an external force pushes the engagement release portion 23 is formed on the left side and the right side of the open area.

Das Verriegelungsglied 24 kann sich in der Längsrichtung der Verbindungsstruktur S bewegen und verhindert eine Verschiebung des Eingriffsabschnitts 22 in eine Richtung des Ausrückens aus der Öffnung in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist. Das Verriegelungsglied 24 umfasst das stangenförmige Glied 241, eine Auskragung 242, einen Spitzenendabschnitt 243, einen Zurückziehverhinderungsabschnitt 245, einen Betätigungsabschnitt 246, einen ersten Positionierabschnitt 247 und einen zweiten Positionierabschnitt 248.The locking member 24 can move in the longitudinal direction of the connection structure S and prevents the engaging portion 22 from being displaced in a direction of disengagement from the opening in a state in which the locking member 24 is pushed in toward the first connector 1 side. The locking member 24 includes the rod-shaped member 241, a projection 242, a tip end portion 243, a retraction preventing portion 245, an operating portion 246, a first positioning portion 247, and a second positioning portion 248.

Der stangenförmige Abschnitt 241 ist ein langes Teil, das sich von vorne nach hinten erstreckt, und die Auskragung 242 und der Spitzenendabschnitt 243 sind nahe einem Spitzenende des stangenförmigen Abschnitts 241 ausgebildet. Wenn das Verriegelungsglied 24 zu dem ersten Verbinder 1 eingeschoben wird, biegt sich der stangenförmige Abschnitt 241 infolgedessen, dass sich die Auskragung 242 entlang der schrägen Fläche des Eingriffsabschnitts 22 auf der bezüglich der Auskragung 221 gegenüberliegenden Seite nach vorne bewegt, nach unten.The rod-shaped portion 241 is a long piece that extends from the front to the rear, and the projection 242 and the tip end portion 243 are formed near a tip end of the rod-shaped portion 241. When the locking member 24 is inserted toward the first connector 1, the rod-shaped portion 241 bends downward as a result of the projection 242 moving forward along the inclined surface of the engaging portion 22 on the opposite side from the projection 221.

Wie in Figur 5(b) gezeigt wird, trifft die Auskragung 242 in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 nicht zusammengefügt sind und das Verriegelungsglied 24 nicht zu dem ersten Verbinder 1 eingeschoben ist, auf den Absatz D. Infolgedessen, dass die Auskragung 242 auf Absatz D trifft, wird das Verriegelungsglied 24 in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 nicht zusammengefügt sind, in einer vorbestimmten Position gehalten, ohne sich vorwärts zu bewegen.As in Figure 5 (b) is shown, meets the projection 242 in a state in which the first connector 1 and the second connector 2 are not mated and the locking member 24 is not inserted to the first connector 1, on the step D. As a result, the projection 242 on Paragraph D hits, the locking member 24 is in a state in which the first Connector 1 and the second connector 2 are not mated together, held in a predetermined position without moving forward.

Das heißt, das Verriegelungsglied 24 kann sich in einem Zustand, in dem der erste Verbindungsanschluss 10 und der zweite Verbindungsanschluss 20 zusammengefügt sind, auf der Seite des ersten Verbinders 1 bis zu einer vorbestimmten Position bewegen und bewegt sich in einem Zustand, in dem der erste Verbindungsanschluss 10 und der zweite Verbindungsanschluss 20 nicht zusammengefügt sind, nicht bis zu der vorbestimmten Position. Dadurch, dass der zweite Verbinder 2 eine solche Konfiguration aufweist, kann ein Benutzer aufgrund dessen, dass sich das Verriegelungsglied 24 nicht vorwärtsbewegen lässt, sicherstellen, dass der erste Verbinder 1 und der zweite Verbinder 1 nicht zusammengefügt sind. Deshalb ist es möglich, einen Versand des Produkts in einem Zustand, in dem der erste Verbinder und der zweite Verbinder 2 nicht zusammengefügt sind, zu verhindern.That is, the locking member 24 can move in a state in which the first connection terminal 10 and the second connection terminal 20 are fitted together on the first connector 1 side up to a predetermined position, and moves in a state in which the first Connection terminal 10 and the second connection terminal 20 are not joined together, not up to the predetermined position. By having the second connector 2 having such a configuration, a user can ensure that the first connector 1 and the second connector 1 are not mated together because the locking member 24 cannot be advanced. Therefore, it is possible to prevent the product from being shipped in a state where the first connector and the second connector 2 are not mated.

Der Spitzenendabschnitt 243 kommt in einem Zustand, in dem der erste Verbinder und der zweite Verbinder nicht zusammengefügt sind und das Verriegelungsglied 24 nicht zu dem ersten Verbinder 1 eingeschoben ist, auf der gegenüberliegenden Seite des Eingriffsabschnitts 22 mit einer Fläche des langen Harzglieds, an der die Auskragung 221 ausgebildet ist, in Berührung. Wenn sich der zweite Verbinder 2 zu der Seite des ersten Verbinders 1 bewegt, bewegt sich die Auskragung 221 nach unten, und infolgedessen bewegt sich auch der Spitzenendabschnitt 243 nach unten.The tip end portion 243 comes in a state in which the first connector and the second connector are not mated and the locking member 24 is not inserted to the first connector 1, on the opposite side of the engaging portion 22 with a surface of the long resin member on which the Projection 221 is formed in contact. When the second connector 2 moves to the first connector 1 side, the projection 221 moves downward, and as a result, the tip end portion 243 also moves downward.

Ein Zurückziehverhinderungsabschnitt 244R und ein Zurückziehverhinderungsabschnitt 244R sind Absätze zur Verhinderung eines Zurückziehens des Verriegelungsglieds 24 aus dem zweiten Gehäuse 21. Der Zurückziehverhinderungsabschnitt 244R und der Zurückziehverhinderungsabschnitt 244L treffen auf an dem zweiten Gehäuse 21 ausgebildete Vorsprünge (nicht gezeigt), so dass ein nachhinten Ziehen des Verriegelungsglieds 24 unwahrscheinlich ist.A retraction preventing portion 244R and a retraction preventing portion 244R are shoulders for preventing retraction of the locking member 24 from the second housing 21. The retraction preventing portion 244R and FIG Withdrawal prevention portions 244L meet projections (not shown) formed on the second housing 21, so that rearward pulling of the locking member 24 is unlikely.

Der Verformungsverhinderungsabschnitt 245 ist eine sich in einer Vertikalrichtung erstreckende Rippe, die in einem Zustand, in dem das Verriegelungsglied 24 nicht zu der Seite des ersten Verbinders 1 eingeschoben ist, mit dem Eingriffsfreigabeabschnitt 23 nicht in Berührung kommt und in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, eine nach unten verlaufende Verformung des Eingriffsfreigabeabschnitts 23 verhindert. Infolgedessen wird in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, der Eingriffsabschnitt 22 nicht von der Öffnung 12 getrennt, selbst wenn eine äußere Kraft an den Eingriffsfreigabeabschnitt 23 angelegt wird.The deformation preventing portion 245 is a rib extending in a vertical direction that does not come into contact with the engagement release portion 23 in a state where the locking member 24 is not pushed in to the first connector 1 side and in a state where the locking member 24 is inserted to the side of the first connector 1, the engaging release portion 23 is prevented from being deformed downward. As a result, in a state where the locking member 24 is pushed in to the first connector 1 side, the engaging portion 22 is not separated from the opening 12 even if an external force is applied to the engaging releasing portion 23.

Der Betätigungsabschnitt 246 ist ein Teil, das der Benutzer einsetzt, um das Verriegelungsglied 24 in Längsrichtung zu bewegen, und umfasst einen Absatz, auf dem ein Benutzer einen Nagel ergreifen kann. Die laterale Breite des Betätigungsabschnitts 246 ist größer als die laterale Breite eines offenen Abschnitts am hinteren Ende des zweiten Gehäuses 21.The operating portion 246 is a part that the user uses to move the locking member 24 in the longitudinal direction, and includes a shoulder on which a user can grasp a nail. The lateral width of the operating portion 246 is larger than the lateral width of an open portion at the rear end of the second housing 21.

Ein erster Positionierabschnitt 247R und ein erster Positionierabschnitt 247L und ein zweiter Positionierabschnitt 248R und ein zweiter Positionierabschnitt 248L sind Aussparungen zur Bestimmung der Position des Verriegelungsglieds 24 in der von vorne nach hinten verlaufenden Richtung. Der erste Positionierabschnitt 247R und der erste Positionierabschnitt 247L nehmen einen Vorsprung 211R bzw. einen Vorsprung 211L, die am zweiten Gehäuse 21 ausgebildet sind, in Eingriff, wodurch es möglich wird, zu verhindern, dass sich das Verriegelungsglied 24 in einem Zustand, in dem das Verriegelungsglied 24 nicht zu der Seite des ersten Verbinders 1 eingeschoben ist, ohne irgendeine Benutzerbetätigung bewegt. Der zweite Positionierabschnitt 248R und der zweite Positionierabschnitt 248L nehmen den Vorsprung 211R bzw. den Vorsprung 211L in Eingriff, wodurch es möglich wird, zu verhindern, dass sich das Verriegelungsglied 24 in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, bewegt.A first positioning portion 247R and a first positioning portion 247L and a second positioning portion 248R and a second positioning portion 248L are recesses for determining the position of the locking member 24 in the front-rear direction. The first positioning portion 247R and the first positioning portion 247L engage a projection 211R and a projection 211L, respectively, formed on the second housing 21, thereby making it possible to to prevent the locking member 24 from moving in a state in which the locking member 24 is not pushed in to the side of the first connector 1 without any user operation. The second positioning portion 248R and the second positioning portion 248L engage the protrusion 211R and the protrusion 211L, respectively, thereby making it possible to prevent the locking member 24 from moving in a state where the locking member 24 to the first connector 1 side is inserted, moves.

Figur 6 ist eine schematische Darstellung zur Veranschaulichung der Funktion des Verriegelungsglieds 24. Figur 6(a) ist eine Schrägansicht der Oberseite des ersten Verbinders 1 und des zweiten Verbinders 2. Figur 6(b) ist eine Querschnittsansicht entlang der Linie A-A in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 nicht zusammengefügt sind. Figur 6(c) ist eine Querschnittsansicht entlang der Linie A-A in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 zusammengefügt sind und das Verriegelungsglied 24 nicht zu der Seite des ersten Verbinders 1 eingeschoben ist. Figur 6(d) ist eine Querschnittsansicht entlang der Linie A-A in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 zusammengefügt sind und das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist. Figure 6 is a schematic representation to illustrate the function of the locking member 24. Figure 6 (a) FIG. 12 is an oblique view of the top of the first connector 1 and the second connector 2. Figure 6 (b) Fig. 14 is a cross-sectional view taken along the line AA in a state where the first connector 1 and the second connector 2 are not joined together. Figure 6 (c) 13 is a cross-sectional view taken along the line AA in a state where the first connector 1 and the second connector 2 are fitted together and the locking member 24 is not pushed in to the first connector 1 side. Figure 6 (d) 13 is a cross-sectional view taken along the line AA in a state where the first connector 1 and the second connector 2 are fitted together and the locking member 24 is pushed to the first connector 1 side.

Wie in Figur 6(c) gezeigt wird, ist die Auskragung 242 in einem Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 zusammengefügt sind, in dem offenen Teil 224 eingeführt und nimmt einen Zustand der Berührung mit der Innenfläche des ersten Gehäuses 11 am hinteren Ende (auf der Seite des zweiten Verbinders 2) der Öffnung 12 ein. In diesem Zustand ist der stangenförmige Abschnitt des Verriegelungsglieds 24 nach unten gebogen.As in Figure 6 (c) As shown, the projection 242 in a state in which the first connector 1 and the second connector 2 are mated is inserted into the open part 224 and takes a state of contact with the inner surface of the first housing 11 at the rear end (on the Side of the second connector 2) of the opening 12 a. In this state, the rod-shaped portion of the locking member 24 is bent downward.

Wenn der Benutzer den Betätigungsabschnitt 246 in dem in Figur 6(i) gezeigten Zustand nach vorne schiebt, biegt sich der stangenförmige Abschnitt 241 weiter durch, und der Spitzenendabschnitt 243 wird vorne in die Aussparung 222 eingeführt und trifft auf eine untere Fläche der Aussparung 222. In diesem Zustand ist der Verformungsverhinderungsabschnitt 245 unter dem Eingriffsfreigabeabschnitt 23 positioniert, während der Spitzenendabschnitt 243 auch auf die untere Fläche der Aussparung 222 trifft, so dass im Wesentlichen keine Verformung des stangenförmigen Abschnitts 241 erfolgt, selbst wenn eine den Eingriffsfreigabeabschnitt 23 nach unten drückende äußere Kraft angelegt wird. Das Ausmaß der Verschiebung der Auskragung 221 in eine Richtung des Ausrückens aus der Öffnung 12 in einem Zustand, in dem das Verriegelungsglied 24 in der Aussparung 222 eingeführt ist, ist deshalb kleiner als das Ausmaß der Verschiebung der Auskragung 221 in der Richtung des Ausrückens aus der Öffnung 12 in einem Zustand, in dem das Verriegelungsglied 24 nicht in der Aussparung 222 eingeführt ist.When the user pushes the operating portion 246 forward in the state shown in Figure 6 (i), the rod-shaped portion 241 bends further, and the tip end portion 243 is inserted forwardly into the recess 222 and meets a lower surface of the recess 222. In this state, the deformation preventing portion 245 is positioned below the engagement release portion 23 while the tip end portion 243 also hits the lower surface of the recess 222, so that there is substantially no deformation of the rod-shaped portion 241 even when an external force pushes the engagement release portion 23 downward is created. The amount of displacement of the projection 221 in a direction of disengagement from the opening 12 in a state in which the locking member 24 is inserted into the recess 222 is therefore smaller than the amount of displacement of the projection 221 in the direction of disengagement Opening 12 in a state in which the locking member 24 is not inserted into the recess 222.

Infolgedessen ist die Verbindungsstruktur S derart, dass sich der Eingriffsfreigabeabschnitt 23 bei Anlegen einer äußeren Kraft an den Eingriffsfreigabeabschnitt 23 in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, dahingehend verformt, eine kleinere Belastung als die Belastung anzulegen, die erforderlich ist, damit sich der Eingriffsabschnitt 22 zu einem Zustand verformt, in dem er aus der Öffnung 12 ausgerückt werden kann. Demgemäß wird der Eingriffsabschnitt 22 nicht aus der Öffnung 12 ausgerückt, und ein Zustand, in dem der Eingriffsabschnitt 22 in der Öffnung 12 eingeführt ist, wird aufrechterhalten.As a result, the connection structure S is such that when an external force is applied to the engagement release portion 23 in a state in which the locking member 24 is pushed to the first connector 1 side, the engagement release portion 23 deforms to apply a smaller load than the load , which is necessary for the engaging portion 22 to deform to a state in which it can be disengaged from the opening 12. Accordingly, the engaging portion 22 is not disengaged from the opening 12, and a state in which the engaging portion 22 is inserted into the opening 12 is maintained.

Wenn unterdessen in einem Zustand, in dem das Verriegelungsglied 24 nicht zu der Seite des ersten Verwenders 1 eingeschoben ist, eine äußere Kraft an den Eingriffsfreigabeabschnitt 23 angelegt wird, verformt sich der Eingriffsfreigabeabschnitt 23 dahingehend, die Belastung anzulegen, die dazu erforderlich ist, den Eingriffsabschnitt 22 zu einem Zustand zu verformen, in dem er aus der Öffnung ausgerückt werden kann. Wenn der Benutzer in diesem Zustand eine den ersten Verbinder 1 und den zweiten Verbinder 2 trennende Kraft anlegt, kann der Verbinder 2 von dem ersten Verbinder 1 entfernt werden.Meanwhile, when in a state where the locking member 24 does not turn to the side of the first User 1 is inserted, an external force is applied to the engagement release portion 23, the engagement release portion 23 is deformed to apply the load necessary to deform the engagement portion 22 to a state in which it can be disengaged from the opening. In this state, if the user applies a force separating the first connector 1 and the second connector 2, the connector 2 can be removed from the first connector 1.

[Durch die Verbindungsstruktur S gebotener Vorteil][Advantage offered by the connection structure S]

Wie oben beschrieben wird, umfasst der zweite Verbinder 2 der Verbindungsstruktur S gemäß dieser Ausführungsform das zweite Gehäuse 21, das um den zweiten Verbindungsanschluss 20 herum vorgesehen ist und den Eingriffsabschnitt 22 aufweist, der in einem Zustand, in dem der erste Verbindungsanschluss 10 des ersten Verbinders 1 und der zweite Verbindungsanschluss 20 des zweiten Verbinders 2 zusammengefügt sind und das zweite Gehäuse 21 mit dem ersten Gehäuse 11 zusammengefügt ist, in die in dem ersten Gehäuse 11 ausgebildeten Öffnung 12 eingreift, und das Verriegelungsglied 24, das sich in die Längsrichtung der Verbindungsstruktur S bewegen kann und eine Verschiebung des Eingriffsabschnitts 22 in eine Richtung des Ausrückens aus der Öffnung 12 in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, verhindert. Dadurch, dass der zweite Verbinder 2 diese Konfiguration aufweist, wird der Eingriffsabschnitt 22 in einem Zustand, in dem das Verriegelungsglied 24 zu der Seite des ersten Verbinders 1 eingeschoben ist, nicht aus Öffnung 12 ausgerückt, so dass ein Zustand, in dem der erste Verbinder 1 und der zweite Verbinder 2 sicher zusammengefügt sind, leicht aufrechterhalten wird.As described above, the second connector 2 of the connection structure S according to this embodiment includes the second housing 21 provided around the second connection terminal 20 and having the engaging portion 22 that is in a state where the first connection terminal 10 of the first connector 1 and the second connection terminal 20 of the second connector 2 are fitted together, and the second housing 21 is fitted together with the first housing 11, engaging the opening 12 formed in the first housing 11, and the locking member 24 extending in the longitudinal direction of the connection structure S. can move and prevent displacement of the engaging portion 22 in a direction of disengagement from the opening 12 in a state in which the locking member 24 is pushed in to the first connector 1 side. With the second connector 2 having this configuration, the engaging portion 22 is not disengaged from the opening 12 in a state in which the locking member 24 is inserted to the side of the first connector 1, so that a state in which the first connector 1 and the second connector 2 are securely fitted together, is easily maintained.

Ferner kann sich das Verriegelungsglied 24 in einem Zustand, in dem der erste Verbindungsanschluss 10 und der zweite Verbindungsanschluss 20 zusammengefügt sind, bis zu einer vorbestimmten Position auf der Seite des ersten Verbinders 1 bewegen und bewegt sich in einem Zustand, in dem der erste Verbindungsanschluss 10 und der zweite Verbindungsanschluss 20 nicht zusammengefügt sind, nicht bis zu der vorbestimmten Position. Dadurch, dass der zweite Verbinder 2 eine solche Konfiguration aufweist, kann der Benutzer aufgrund dessen, dass sich das Verriegelungsglied 24 nicht vorwärtsbewegen lässt, sicherstellen, dass der erste Verbinder 1 und der zweite Verbinder 2 nicht zusammengefügt sind, so dass der erste Verbinder und der zweite Verbinder 2 sicher zusammengefügt werden können.Further, the locking member 24 can move to a predetermined position on the first connector 1 side in a state in which the first connection terminal 10 and the second connection terminal 20 are mated, and moves in a state in which the first connection terminal 10 and the second connection terminal 20 are not mated together, not up to the predetermined position. By having the second connector 2 having such a configuration, the user can ensure that the first connector 1 and the second connector 2 are not mated together due to the locking member 24 not moving forward, so that the first connector and the second connector 2 can be safely joined together.
