Field of the Invention

The present invention refers to a electrical plug connector. The electrical plug connector comprises a contact area for the housing of one end driver. The contact area is used to establish a electrical contact with the conductive end housed. A clamping device for fixing by tightening the end driver in the contact area.

State of the art

Electrical plugs protected against water, single pole, particularly for applications within the photovoltaic industry, they are usually provided with an electric conductor, when the conductor is crimped to a contact element. Crimping requires a special tool to produce the union by crimp. In addition, after being effected, a crimp joint can no longer be separated.

By application DE 196 13 557 a known connection terminal with a bending spring. Connecting spring It is shaped relatively complex and, in all case, a high force must be used to close the terminal of Connection. On the other hand, the loading arm is relatively long and the connection terminal relatively large and difficult to handle. To its instead, there is the disadvantage that the conductive end only It can be entered when the contact terminal is open. Likewise, in the tensile load, a component of force, which acts in the opening direction on the arm of load, which requires a high preload or may damage to contact security. In addition, the connection terminal for insert the plug is on a busbar and is not suitable to establish a separate contact.

Usually the plug connectors Electrical are made up of individual components. After application and fastening of one of the ends of the cable in one of the components, the individual parts must to be united to each other for the formation of a unit, the which electrically insulates the driver outwards and protect from moisture.

General Description of the Invention

Therefore, the object of the present invention is the simplify the connection of electrical conduits, for example, in plug connectors and enable a manual connection, in particular without the use of a special tool.

The present invention refers to a electrical plug connector with a first and a second subgroup of pieces. The first subgroup comprises a contact area for the accommodation of a conductive end and for the establishment of a electrical contact with the conductive end housed. Also, the first subgroup comprises a clamping device for fixing by tightening the conductive end 40 in the contact area. He second subgroup of parts comprises a recessed body with a recessed space for housing contact area. The first and the second subgroup of pieces are one piece and, it they find shaped so that, when they are open, can unlock the clamping device for manual adjustment by tightening the conductive end and, when closed, they can electrically isolate the contact area and even the clamping device

The advantage of the plug connector according to The invention resides in its one-piece conformation. Without However, this does not mean that the subgroups of parts should be made of an individual piece, that is, of a piece Individual preformed. Rather, both subgroups of pieces, the which, for example, can be made up of pieces preformed molded separately, may also, upon meeting open the plug connector, be fixed to each other, of so that the subgroups of plug connector parts are Find together. In this way, the subgroups of parts are They are always available. At the same time, both subgroups of parts are shaped so that the connector of Plug can be displaced in two positions. An open position Unlocks the clamping device. In this position, the end conductor can be inserted and fixed in the plug connector. The closed position allows an electrical isolation of the area of contact and protection against moisture or dirt. An object joined separately with two positions simplifies the use of the plug connector for the user.

Preferably, the contact area and even the clamping device is shaped movable within the recessed space of the recessed body. To be placed the plug connector in the closed position, the body recessed forms a mechanical protection against moisture and dirt. Simultaneously, the hollowed body can deal with the electrical insulation of the contact area with respect to the medium ambient. Preferably, the hollowed body is shaped so that, when closed, it can clog hermetically the contact area and even the device squeeze in. The humidity is particularly severe, since it can lead to short circuit or conductor corrosion. For this, in particular, can be provided with a pressure crown, which, when the plug connector is sealed, compress a wrap elastomeric compact, so that the closure is airtight.

According to a preferred form of execution of the present invention, the first subgroup of parts comprises a seal ring for sealing the contact area with the end hosted driver The hollowed body preferably has a External thread for screwing with retaining ring. The body recessed screwed with the retaining ring isolates the area of Contact.

Likewise, a device of interlocking for the first and second disconnectable lock subgroup of pieces when they are open and / or closed. Blocking In open position it has several advantages. This way it simplifies the insertion of the conductive end in a formation firmly locked from the first and second subgroup of pieces. He access to the clamping device is also stable, so that its drive can be carried out quickly and free of disturbances Also in a closed position a lock is advantageous disconnectable Thus, both positions, open and closed, They are uniquely defined with respect to mechanics.

According to a preferred form of execution of the present invention, the plug connector comprises a linear address for the address of the first and second subgroups, relatively from one to the other, along a path linear. As linear direction is understood an element of a machinery, which allows a translation, as far as possible without friction, of the mobile subgroups and, at the same time, guarantees the observation of the direction of movement - one way linear.

Preferably, the linear direction It comprises two directional elements, which, so telescopic, can move inside each other. The first subgroup can present the first directional element and the second Subgroup comprises the second directional element. At the same time, the directional element can serve as a contact pin for the plug connector For this, for example, the first element directional can be electrically attached to the first subgroup with the contact area.

The following describes the example of Execution of the present invention by reference to the drawings. Figure 1 represents in perspective a first subgroup of electrical plug connector parts of the present invention. The subgroup of parts 10 comprises the contact area 30, in the which contact can be established with respect to one end driver. The conductive end is fitted in the contact area 30 through an opening in a retaining ring 80. The direction of the fit is preferably as in the example shown, at along the direction, along which they can move both subgroups of pieces 10, 20, relatively one with respect to the other. The conductive end is fixed by tightening the contact to through the clamping device 50. The clamping device 50 It is shaped like a spring, which can be operated manually. Finally, a first element is represented directional of the first subgroup. This first directional element it serves, first, for the mechanical directionality of the first subgroup 10 with respect to the second subgroup 20; Secondly It transmits the electrical current from the conductive end.

Figure 2 shows a perspective view of the first and second subgroup of plug connector parts electrical of the exemplary embodiment. In this representation, the first and second subgroup of pieces 10 and 20 are They are represented in an open position. In this way, so In general, the plug connection is provided. First, the user must direct a conductive end to the contact area 30 to through an opening (which is not represented) in the retaining ring 80. The conductive end is fixed by tightening the contact area 30 through the clamping device 50. At its once, an outer thread 90 is provided in the second subgroup of parts 20. The first and second subgroups of parts are thus inserted into each other and seal ring 80 is screwed With the outer thread. The advantage of this form of execution resides in that the subgroups of pieces 10 and 20 are made up of one piece. This means that the user always It has both necessary subgroups available. Not required, by therefore, a difficult fit of the subgroups of pieces one inside of the other. The displacement of the subgroups of parts takes place by a linear address (which is not represented in detail) between both subgroups of pieces. Reference 120 call the female part of the plug connector again. This piece simultaneously forms part of a linear direction of the electrical plug connector. This second directional element 120 is pushed by a corresponding piece of the opposite plug, to establish an electrical contact. For mechanical anchoring of Inserted electrical plug connector two springs of the plug 120, which fit into a corresponding cavity of the opposite plug to establish a continuous mechanical connection.

Figure 3 shows a side top view of the electrical plug connector of the execution example Preferred in open position. In figure 4 a sectioned image of the electrical plug connector. In this representation is presented, for the first time, the lateral opening 150 for the accommodation of the conductive end. The driving end can be inserted up to the contact area in the connector Plug. With the contact area 30, a frame of interlock 50, with which the end can be contacted driver. The clamping device 50 comprises a clamping side 52, which is rotatably mounted on the frame of interlocking and which can be balanced in a reciprocating motion between an open rotating position and a rotating position closed.

The tightening side 52, in a rotating position closed, press the conductive end against the contact area 30 when the conductive end is placed in the contact position desired to establish electrical contact between the end conductor and contact section 30. Rotating side 52 is rotatably displaced by the contact segment 30 in the open position The conductive end, on the one hand, can be introduced in the open rotating position and, on the other hand, is Unlocked for extraction. The tightening side 52 extends in the rotating position closed obliquely with respect to the contact section and is mobile shaped on springs Thus, the leading end in the position swivel closed, can be introduced in the contact position desired by elastic recovery of the tightening side 52. To improve the insertion of the conductive end and the tightening of the conductive end with respect to a tensile load engaged in the driver, the tightening side is shaped inclined towards the direction of insertion, so that an angle is formed sharp between the conductor and the surface, which is in contact with the driver, as well as with the surface indicated by the driver on the tightening side 52.

The tightening spring 50 is shaped Like an angular lever Between a drive side 54 and a tightening side 52 an angled segment is arranged folded in V 56. On the drive side 54, the layered segment 56 and clamping side 52 is essentially a V shape. When the drive side 54 is pressed down, the side of press 52 is pressed against the conductive end, as well as over the contact area The tightening side 52 pressed down can be blocked, so that the conductive end and the area of Contact can be tightly tightened.

Figure 4 also shows a linear address for the address of the first and second subgroups 10, 20, relatively one relative to the other, along one linear track The linear direction comprises two elements directional 110 and 120, which can be inserted inside of the other as a telescope. The first subgroup 10 comprises the first directional element 110 and the second subgroup 20 comprises The second directional element. The second directional element 120 it comprises a hollowed space, which, in its cross section corresponds to the cross section of the first directional element. From In this way, the first directional element can be inserted into The second directional element. Rotary movement is excluded of the first and second directional element towards the direction of insertion through the geometry of the first and second elements directional. Both the recessed space of the second element directional as the external form of the first directional element is they are preferably formed in a cylindrical shape. The first directional element 110 of the first subgroup 10 is is electrically connected to the contact area 30; the second directional element 120 of the second subgroup 20, in position closed, isolates the first directional element 110.

Figure 5 shows an enlarged section of the electrical plug connector according to the preferred embodiment example. In particular, the transfer between the first and second subgroups 10, 20 in the open position is represented. For this, an interlocking device 100 is provided, which is composed of an interlocking boss 102 and an interlocking slot 104. In the locked position, the interlocking boss 102 engages in the interlocking slot 104, so that the Subgroups of pieces 10 and 20 can no longer be moved inside each other in the longitudinal direction. Preferably, a plurality of interlocking grooves 104 are provided in the second subgroup of parts 20, which, preferably, are distributed over the circumference of the second subgroup of parts 20. If the interlocking grooves 104 engage in the projections of corresponding interlocking 102, then, at the same time, a translation of the subgroup of pieces along a longitudinal axis 106 and a rotation along the longitudinal axis 106, relatively from one to the other, is prevented. As soon as the locking of the locking device 102 is activated, both subgroups of parts can be pushed into or out of the other along the longitudinal axis. However, the plug connector consists of a single piece component. The subgroups of pieces cannot, without more, be separated from the
other.

A top side view on the second subgroup of parts 20 is shown again in Fig. 20. An elastomeric compact envelope (which is not shown) is used in a pressure crown 160 at the insertion end of the second subgroup of parts 20 During screwing, the pressure crown is pressed together and compacted with the elastomeric ring against the conductor lining (which is not shown). Finally, in figure 7 the plug connector 5 is shown in closed position.
gives.

Figure 8 shows again the connector of electric plug in open position. The indicated arrows using the reference signs 1S, 2S, 3S and 4S indicate what mode the electrical plug connector is attached to a conductive end 40. In a first step, the conductive end 0 is conducted through opening 150 (which is not found here represented) by the first subgroup of pieces to the area of Contact. As soon as the conductive end reaches the area of contact, the clamping side 52 of the clamping spring 50 rotated by the angled section. The pressure spring is located in this position, slightly prestressed, so that the conductive end 40 It can't even be definitely locked. To achieve fixation spring-loaded from conductive end 40 to the section of contact, then drive segment 54 of the tightening spring 50 is pressed down until it enclave, see reference sign 2S. In this way, it has now established an electrical contact between the conductive end and the contact area Consecutively, both subgroups of parts 10 and 20 are inserted from each other, until retaining ring 80 collides with the outer thread 90 of the second subgroup of parts. In one last step, the thread is screwed into the nut, until the contact area 30 is sealed tightly and electrically insulated out. Preferably, within the first subgroup of parts is expected at least one projection of additional interlocking 106, so that slot 104, in position closed, also engage in the said projection. In this way, in additionally with respect to the threaded closure, a blocking of both subgroups of pieces 10 and 20.

Figure 9 shows a representation in perspective of two electrical plug connectors 5 and 6 connected the each other. An unlocking element 140 is provided for connection of the plug connector, which can be unlocked. Preferably, the unlocking element 140 is a component integral of a plug connector, here the plug connector 6, so that the plug 5 is fully butt on the edge 7 of the unlocking element 140, which is shown in Figure 9. Al same time, figure 9 illustrates how a plug connector Closed electric can be opened to remove the end of a cable or to insert it again. To do this, first, The retaining ring must be unscrewed. The reference sign 1Ö shows in which direction the seal ring 80 must be rotated to be disassembled from the outer thread 90. Next, the projection of interlocking 106 inside the first subgroup of parts 10 must be removed from the interlocking slot 104. To do this, preferably, a wedge or screwdriver is pushed between the first and second component 10 and 20 in the groove area of interlocking 104. Thus, the interlocking slot is removal of the locking projection 196, until the projection 106 no longer engage the interlocking groove 104. Shaped consecutively, both subgroups 10 and 20 are relatively displaced towards each other; see reference sign 3Ö.

Figure 10 shows a plug connector electric in open position after they were carried out steps 1Ö, 2Ö and 3Ö for opening. The reference sign 4Ö shows here how the electrical contact between the conductive end 40 and contact area 30. To this end, the side of drive 54 of the clamping spring is raised in the direction of the 4Ö arrow. Finally, the conductive end 40 may be removed from the electrical plug connector.

Finally, Figure 11 shows two connectors of electrical plug 5, 6 according to the invention, which are They find each other together. The mechanical fixing of the housing of the electrical plug connectors 5, 6 takes place through the plug spring 130, whose projections engage and engage in the cavities 141 covered by the unlocking element 140.

The unlocking element serves, among others things, to avoid involuntary actuation of the spring of the plug, and with it, an involuntary loosening of the connector Plug. To this end, the unlocking element 140 has two respectively opposite barriers 142, which overcover the cavities 141.

To detach the plug connector electric, the springs of the plug 130 are pressed out from the groove of the connecting element, for example, by means of a screwdriver. Then the electrical plug connectors 5, 6 can be extracted from each other in the direction of the arrow. In this way, the unlocking element is fixed in movable shape on plug connector 6 transversely with with respect to the direction of arrow 2. Also, within the Unlocking element is provided drive elements, the which move like springs radially inwards, which act on the ends of the plug springs 130. By placing the screwdriver, the element of drive is moved radially inward by dragging to the springs of the plug, so that they move in shape radial inwards from the cavity. Simultaneously, the element of unlocking 140, by placing the screwdriver in the opening is moved between the cover and the cavity in the opposite direction and thus acts on the element of drive located opposite, which, likewise, is moved radially inward, so that the other also plug spring bends radially inward and moves out of the cavity 141 its locking projection. Both of them plug connectors 5, 6 can be removed from each other and, from This way, be separated.

It is obvious to the expert that the form of Execution described above should be understood as an example and that the present invention is not restricted thereto, but which can be modified in various ways, without departing from it of the invention. It is also evident to the expert that the characteristics are independent with respect to whether are disclosed in the description, the claims, the figures or otherwise, since they also define components individual fundamentals of the invention and can be considered separately for the protection area restriction, including also when they are described jointly with others features.
