Description

The invention relates to a device for inserting a contact blade in a socket of a connector according to the preamble of claim 1 and a method for inserting a contact blade in a socket of a connector.

Electrical connectors conventionally have a plug receptacle (so-called female part) into which a plug (so-called male part) is to be inserted. An electrical contact is in this case made via one or more sockets of the connector receptacle into which one or more contact pins of the plug are to be inserted, so that in the plugged state, the sockets and the contact pins are electrically contacted.

At one of the DE 10 2011 050 938 A1 Known connector of this type is a cable plug with electrical contacts in sockets of an associated device plug to insert. The cable connector is provided for establishing an electrical connection between an electric vehicle and a charging device for charging a vehicle battery associated with the electric vehicle.

Another connector of this kind is for example from the WO 2012/159950 A1 known.

Electrical connectors that serve to connect an electric vehicle to a charging device for charging a battery of the electric vehicle, must be for transmitting large currents, such as currents greater than 50 A up to z. B. 400 A, be designed. A charge current for an electric vehicle may be, for example, in the range between 200 and 250 A. Accordingly, a socket must be dimensioned and designed in cooperation with an associated electrical contact pin to provide a low-resistance electrical contact.

In addition, electrical connectors on charging devices and electric vehicles are often operated several times a day and to electrical contact pins of a plug are plugged into associated sockets of a connector receptacle. Such connectors must therefore be resistant and wear-resistant, so that even after a large number of operations, a reliable electrical contact for a low-resistance electrical connection can still be produced.

In order to produce an advantageous electrical contact between a socket and an associated pin in the high current range for currents greater than 50 A, a contact blade is provided on the socket, which is inserted into the socket and is seated in a contact of the socket. The contact blade is at least partially resilient and serves to engage with an inserted contact pin to make electrical contact between the socket and the contact pin.

Since in particular such contact blades can be subject to wear, there is a need to be able to replace the contact blades. In conventional connectors, which has come to a wear on one or more contact blades of one or more sockets, it has often been necessary to replace a connector receptacle arranged thereon sockets in total, which can be associated with a lot of effort, especially if the plug receptacle is disposed in an engine compartment or other space within a vehicle in a manner not readily accessible. If a contact blade is traditionally exchanged without removing a plug receptacle, the contact blade may optionally be removed from a socket, for example, with pliers. However, the insertion of another contact blade in the socket must then be done by hand and / or using a tool, such as a pair of pliers. The use of a tool such. B. a pair of pliers always carries the risk of damaging the new contact blade when inserted into the connector receptacle. In the worst case, even the plug receptacle itself can be damaged. Is the contact blade provided with a sensitive coating, which z. B, good contact with good sliding properties causes, then it should not be touched by hand.

From the US 4,164,065 For example, a crimping machine is known in which, after crimping a terminal having a lead wire, the lead wire together with the terminal is inserted into a receptacle of a connector housing.

From the DE-AS 15 90 124 a socket for electrical contact devices is known. The electrical contact socket contains within a rigid tube part a plurality of rectilinear wires, which can be geometrically diverged by rotation about the axis of the part and are inclined relative to this axis.

From the DE 10 2011 078 350 A1 For example, a spindle-shaped plug-in tool is known in which a spindle is configured to position a member in an open end of a port.

Object of the present invention is to provide an insertion device and a method for inserting a contact blade in a socket of an electrical connector, which allow a simple, reliable insertion of a (new) contact blade in a socket of a connector.

This object is achieved by an article having the features of claim 1.

• – ein Ansetzstück, in dem die Kontaktlamelle in einem Ausgangszustand aufgenommen ist und das an eine Buchse, in die die Kontaktlamelle einzusetzen ist, ansetzbar ist, und
• – ein relativ zu dem Ansetzstück verstellbares Verstellelement, das in dem Ausgangszustand eine erste Stellung relativ zum Ansetzstück einnimmt, wobei die Kontaktlamelle bei an die Buchse angesetztem Ansetzstück durch Verstellen des Verstellelements aus der ersten Stellung in die Buchse einsetzbar ist.

Accordingly, the insertion device comprises

• - An Ansetzstück in which the contact blade is received in an initial state and which is attachable to a socket into which the contact blade is to be inserted, and
• - An adjustable relative to the Ansetzstück adjustment, which occupies a first position relative to the Ansetzstück in the initial state, wherein the contact blade is inserted in attached to the female Ansetzstück by adjusting the adjustment of the first position in the socket.

The present invention is based on the idea to provide a special tool that allows a simple, reliable way inserting a contact blade into a socket of a connector. For this purpose, the insertion device on an attachment piece, in which the contact blade is received before insertion into the socket. The Ansetzstück can be attached to the socket and carries a relative to the Ansetzstück adjustable adjustment that occupies a first position relative to the Ansetzstück before inserting the contact blade into the socket and can be adjusted for insertion of the contact blade in the socket from the first position to introduce in this way the contact blade of the attachment piece in the socket.

By means of the insertion device, a tool is provided, with which a contact blade can be inserted in a simple manner into a socket of a connector, without the contact blade having to be touched by a user or handled with unsuitable tools for this purpose.

For this purpose, the adjustment element is preferably displaceably guided along an insertion direction in a receiving chamber of the attachment piece. In the initial state, the contact blade is received in the receiving chamber of the attachment piece and can be pushed out of its first position in the insertion direction out of the receiving chamber and into the socket by moving the adjustment. By pressing the adjusting element, the contact blade is inserted into the socket, for which purpose the adjusting acts in the manner of a punch on the contact blade and the contact blade from the example cylindrically shaped receiving chamber of the attachment piece pushes out.

The approximately annular contact blade is preferably received in the initial state by clamping in the receiving chamber by biasing against a (cylindrical) inner wall of the receiving chamber and is added thereto under bias on the inner wall. In an advantageous embodiment, the adjusting element has an adjusting shaft, which in the initial state reaches through the contact blade when the contact blade is received in the attachment piece. By adjusting the adjustment for inserting the contact blade in the socket of the adjustment shaft is at least partially off from the attachment piece and retracted into the socket and takes on his adjustment with the contact blade, so that the contact blade is inserted into the socket.

The Verstellschaft, for example, have an end surface which is approximated at an adjustment of the adjusting a bottom of the bushing and comes into engagement with the retracted into the socket Verstellschaft with the bottom of the bush, so that the Verstellschaft in cooperation with the sleeve has a defined end position, in which it is ensured that the contact blade is properly inserted into the socket.

The adjustment element preferably has a stop section on its adjusting shaft, which is designed to act upon adjustment of the adjusting element for insertion of the contact blade into the bushing on the contact blade. The stopper portion realizes a driver, which carries the contact blade when adjusting the adjustment relative to the attachment piece and thus transferred from the receiving chamber of the attachment piece in the socket. By way of the abutment section, the adjustment element may, for example, also be guided on a (cylindrical) inner wall of the attachment piece, so that the adjustment element can be moved in a defined, guided manner relative to the attachment piece.

The attachment piece has, for example, an intermediate wall which limits the receiving chamber of the attachment piece against the insertion direction. The stop portion of the adjusting element is in the first position (before inserting the contact blade in the socket) on the intermediate wall, so that the first position of the adjusting element is defined by the abutment of the stopper portion on the intermediate wall. To insert the contact blade into the socket, the adjusting element is adjusted and thereby moved out of its first position, whereby the stopper portion of the Removed intermediate wall and moved in the receiving chamber of the socket and thereby entrains the contact blade and introduces into the socket.

To the abutment portion of the adjustment advantageously includes on a side facing away from the adjustment shaft on an actuating shaft, which passes through the intermediate wall and carries an actuating head for actuating the adjusting element. About the operating shaft, the adjusting element can be actuated by a user in a simple manner, for example, by the user presses on the actuating head and thereby pushes the operating shaft into the attachment piece, whereby the stopper portion moves in the receiving chamber of the attachment piece and the adjustment shaft is moved out of the receiving chamber.

The attachment piece and the adjusting element are, for example, substantially cylindrically shaped and thus at least approximately rotationally symmetrical with respect to the insertion direction. In particular, while the receiving chamber of Ansetzstücks is formed circular cylindrical, so that the at least approximately annular contact blade can be held in the receiving chamber. To insert the contact blade in the socket, the contact blade can then be moved by adjusting the adjustment along the cylindrical inner wall of the receiving chamber and introduced into the likewise cylindrically shaped contact receiving the socket.

In a further embodiment, the attachment piece has a recess to be brought into engagement with the bushing at an end section to be attached to the bushing, which allows a defined attachment of the attachment piece to the bushing. The recess may for example be shaped according to a head of the socket into which the contact blade is to be inserted, so that the head of the socket can be accurately inserted into the recess of the attachment piece and the attachment piece thus, when it is attached to the socket, a has defined position relative to the socket.

The insertion device has a spring element which biases the adjusting element relative to the attachment piece in the direction of the first position. The spring element in this case serves, on the one hand, to hold the adjusting element in its first position, so that the adjusting element can not be readily displaced out of the first position, in particular in the case of delivery with a contact blade held on the attachment piece. Thus, the contact blade is taken up safely and protected in the insertion until the moment of insertion. Secondly, after the adjusting element has been adjusted, the spring element effects a return of the adjusting element in the direction of its first position out of the socket.

The spring element may, for example, designed in the manner of a compression spring and arranged on the actuating shaft between the actuating head and the intermediate wall of the attachment piece, so that the spring element biasing acts between the actuating head and the intermediate wall of the attachment piece and thus biases the adjustment relative to the attachment piece.

• – wird eine Einsetzeinrichtung mit einem Ansetzstück, in dem die Kontaktlamelle in einem Ausgangszustand aufgenommen ist, an eine Buchse, in die die Kontaktlamelle einzusetzen ist, angesetzt,
• – nimmt ein relativ zu dem Ansetzstück verstellbares Verstellelement der Einsetzeinrichtung in dem Ausgangszustand eine erste Stellung relativ zum Ansetzstück ein und
• – wird durch Verstellen des Verstellelements aus der ersten Stellung die Kontaktlamelle in die Buchse eingesetzt.

The object is also achieved by a method for inserting a contact blade into a socket of a connector. In the process

• An insertion device with an attachment piece, in which the contact blade is received in an initial state, is attached to a socket into which the contact blade is to be inserted,
• - Takes a relative to the attachment piece adjustable adjustment of the insertion in the initial state, a first position relative to the attachment piece and
• - Is used by adjusting the adjustment of the first position, the contact blade in the socket.

The advantages and advantageous embodiments described above for the insertion device are also applied analogously to the method, so that reference should be made to what has been stated above.

By adjusting the adjusting element relative to the attachment piece, the contact blade is pushed out of a receiving chamber of the attachment piece and inserted into a contact receptacle of the socket. In the initial state, the contact blade is in this case clampingly received on an inner wall of the receiving chamber by being rolled in a biasing manner in the circumferential direction, so that sets with the bias of a smaller radius and the contact blade thereby biased against a cylindrical inner wall of the receiving chamber. By adjusting the adjustment element, the contact blade is moved out of the receiving chamber into the contact receptacle of the bush and enters the region of a lamellar seat of the bush, which may have a larger diameter compared to the cylindrical inner wall of the other contact, so that the contact blade in the disk seat at least slightly radially expand and thereby radially removed from the adjustment of the adjustment.

After insertion of the contact blades in the slats seat of the sockets, therefore, the adjusting element thus readily back from the Socket be pulled out, wherein the contact blade remains in the slat seat of the socket. After removal of the inserting device from the socket, the socket with inserted, new contact blade is ready for use and can be brought into engagement with an associated contact pin.

An in 1 illustrated plug receptacle 1 a connector has a housing 10 on, on the plug contacts 11 each with a socket 110 for establishing an electrical connection with an associated, in 1 not shown plug are arranged. On the case 10 are guide sleeves 13 for introducing associated spikes of a plug for mechanical guidance in the manufacture of the connection of the plug receptacle 1 arranged with the plug. A connector 12 used to make a connection for other lines such. B. control lines.

The plug receptacle 1 is the counterpart to the plug, which is attached to the accumulator and is available both on the charging device as well as in the vehicle to connect the accumulator. Accordingly, the accumulator can be charged to or in the charging device and deliver its charge to the vehicle in the vehicle. About the plug contacts 11 For example, a three-wire connection is made for supplying or discharging a current. In particular, when charging a charging current of the order of z. B. 200 to 250 A via the plug contacts 11 ,

To be in such a connector receptacle 1 at the plug contacts 11 providing a reliable, low-impedance connection is on each jack 110 , as in 2A and 2 B represented, a metallic contact blade 2 arranged in a separate representation in 3 is shown. The contact lamella 2 sits in a lamella seat 113 in the interior of a running in the manner of a blind hole contact 112 a head 111 the socket 110 , The contact lamella 2 has a substantially annular shape and is formed by two ring sections 21 . 22 formed, which has axially extending webs 20 connected to each other. The ring sections 21 are in the area of an opening 23 circumferentially open, leaving the contact blade 2 is interrupted in the circumferential direction. The contact lamella 2 sits in the lamella seat 113 , the opposite of the cylindrical contact 112 the socket 110 is radially widened and correspondingly at least a slightly larger diameter than the contact 112 having.

To establish an electrical contact, an associated contact pin is used to make contact 112 the socket 110 inserted and thus comes into contact with the contact blade 2 , Because of the webs 20 the contact blade 2 at least partially elastically resilient, the contact blade sets 2 under spring tension to the in the contact 112 inserted contact pin, so that an electrical contact in particular between the contact blade 2 and the contact pin is made. An electric current can then be transmitted to your head 111 the socket 110 adjoining shaft 114 be derived.

A plug receptacle 1 A charging device or a vehicle must be designed for multiple insertion of an associated connector. In particular, it must be ensured even with repeated, multiple use that over the sockets 110 In a reliable way, a low-resistance electrical contact with inserted pins of a plug can be made.

By multiple insertion of pins in the sockets 110 the plug receptacle 101 It can be especially useful in the jacks 110 arranged contact blades 2 come to wear, requiring an exchange of the contact blades 2 may require. While removing contact blades 2 by means of a suitable tool, for example by means of a pair of pliers, is readily possible, the insertion of new contact blades 2 in the jacks 110 complicated and complicated in its handling. So can the contact blades 2 be coated, for example, on the one hand to allow a good contact with a contact pin and on the other hand, a simple insertion of the contact pin. Such coated contact blades 2 After being coated, they must not be touched by a user (more), so that a manual insertion of new contact lamellae is possible 2 in the contact socket 110 is associated with special requirements.

Therefore, an insertion device 3 provided in an embodiment in 4 to 8th is shown.

The insertion device 3 has a fitting piece 30 and one along an insertion direction I adjustable on the attachment piece 30 guided adjustment 31 on. The attachment piece 30 can have a recess 301 at one end portion 300 (see eg 5B ) of a socket 110 a plug receptacle 1 be prepared and contained in a receiving chamber 302 a contact lamella 2 , which in an initial state in the substantially cylindrically shaped receiving chamber 302 is included.

In the reception room 302 is over a stop section 312 also the adjusting element 31 guided. The adjusting element 31 has an understanding 313 on, in a first position, which is the adjusting element 31 in the initial state of the insertion device 3 occupies substantially within the receiving chamber 302 extends. To the Verstellschaft 313 closes the stop section 312 in the first position at a receiving chamber 302 against the insertion direction I delimiting curtain wall 303 of the attachment piece 30 is applied and thus a defined position relative to the attachment piece 30 occupies.

From the stopper section 312 extends an operating shaft 311 through the partition 303 through and out of the attachment piece 30 against the insertion direction I out. The operating shaft 311 carries on his from the stop section 312 opposite end of an actuator head 310 , the one on the operating shaft 311 held spring element 32 in the form of a compression spring against the partition 303 of the attachment piece 30 is biased.

The spring element 32 serves on the one hand, the adjustment 31 in the initial state of the insertion device 3 to hold in its first position, to prevent unintentional adjustment of the adjustment 31 relative to the attachment piece 30 to prevent. For this purpose, the spring element extends 32 between the partition 303 and the actuator head 310 from a recess 304 of the attachment piece 30 out and clamps the adjustment 31 so opposite the attachment piece 30 before that the adjusting element 31 with its stop section 312 under tension on the partition wall 303 is applied.

In the initial state, shown in 4 . 5A and 5B , the insertion device can 3 along with the in the receiving chamber 302 the attachment piece 30 used contact blade 2 Supplied by a supplier, so at the place of the plug receptacle 1 a new contact blade 2 in a socket 110 the plug receptacle 1 can be used. To protect in the attachment piece 30 held contact blade 2 is here on the end section 300 of the attachment piece 30 a protective cap 33 put on the receiving chamber 302 closes to the outside and thus prevents moisture or dirt from entering the receiving chamber 302 can penetrate.

To replace a contact blade 2 on a socket 110 a plug receptacle 1 the procedure is as follows.

First, an exchanged, possibly worn contact blade 2 by means of a suitable tool, for example by means of pliers, from the socket 110 removed by simply leaving her slat seat 113 from the socket 110 is pulled out.

Then, as in 6 represented, the insertion device 3 with her attachment piece 30 to the socket 110 scheduled, leaving the socket 110 with her head 111 into the recess 301 at the socket 110 facing end portion 300 of the attachment piece 30 intervenes. Before applying the insertion device 3 to the socket 110 becomes the protective cap 33 from the end portion 300 taken. By attaching the attachment piece 30 with the recess 301 to the head 111 the socket 110 becomes the receiving chamber 302 of the attachment piece 30 as well as the Verstellschaft 313 of the adjusting element 31 relative to the socket 110 centered so that the cylindrical inner wall of the receiving chamber 302 at least approximately without offset in the cylindrical inner wall of the contact 112 the socket 110 passes over and the shaft 313 in a centered way in the contact 112 faces inwardly.

Now, as in 8th is shown by pressing on the actuator head 310 the adjusting element 31 (against the spring bias of the spring element 32 ) in the insertion direction I relative to the attachment piece 30 be moved so that the adjustment 313 in the contact 112 is retracted until it with its front end surface 314 in plant with a soil 115 the contact 112 arrives. By adjusting the adjusting element 31 gets over the stopper section 312 , the pretension 313 radially projecting and in sliding contact with the cylindrical inner wall of the receiving chamber 302 of the attachment piece 30 that's in the receiving chamber 302 held contact lamella 2 taken and thereby out of the receiving chamber 302 out in the contact 112 the socket 110 pushed it into the area of the slat seat 113 in contact 112 arrives.

The contact lamella 2 is in the initial state under tension in the receiving chamber 302 of the attachment piece 30 taken by (at least slightly rolled in the circumferential direction (compared to a relaxed state). The contact lamella 2 is thereby in the initial state under bias on the inside of the cylindrical inner wall of the receiving chamber 302 at. Will the contact blade 2 by actuation of the adjusting element 31 from the receiving chamber 302 pushed out and enters it in the area of the slat seat 113 the contact 112 the socket 110 so the contact blade can 2 itself - because of compared to the contact 112 and also to the receiving chamber 302 larger diameter of the slat seat 113 - At least slightly roll, so radially wide, so that the contact blade 2 on the one hand radially in relation to the other Wandungsabschnitten the contact 112 recessed lamella seat 113 engages and secondly at least slightly from the Verstellschaft 313 removed radially. The Verstellschaft 313 can thus by retracting the adjustment 31 , possibly due to the restoring force of the spring element 32 , from the socket 110 be extended, with the contact blade 2 in the slat seat 113 and thus inside the socket 110 remains.

After resetting the adjusting element 31 can the insertion device 3 without further ado from the socket 110 be removed. The insertion process of the contact blade 2 is finished.

The insertion device 3 may for example be made as a disposable plastic, for example, POM (polyoxymethylene) or PEEK (polyetheretherketone). After delivery of the inserter 3 with attached contact blade 2 and after inserting the contact blade 2 in a socket 110 can the insertion device 3 be disposed of.

It is also conceivable, the insertion 3 as a reusable part for repeated use. In this case, the insertion device 3 after successful insertion of a contact blade 2 in a socket 110 again with a contact blade 2 be fitted, then this contact lamella 2 in another socket 110 use.

The idea underlying the invention is not limited to the above-described embodiments, but can also be implemented in a completely different manner in other embodiments.

With the provided insertion means a dedicated tool is provided, which allows in a lighter, easy-to-use manner, a replacement of a wear part in the form of a contact blade in an associated socket of a connector receptacle. The insertion is reduced in this case to a simple operation of an adjustment, without having to directly access the contact blade or other measures for the exact placement of the contact blade would have to be undertaken in the socket.

An insertion device of the type described here is not limited to use on plug receptacles for batteries on vehicles and / or charging devices, but can basically be used anywhere where contact blades are to be used for power contacts in sockets. Such power contacts are used in particular in the high-current range at currents above 50 A.
