Description

Connection socket of an electrical connector like this as an electrical connector equipped with said socket.

The present invention relates to a socket of connection of an electrical plug connector, according to the preamble of claim 1 (DE-AS 1 042 137).

In addition, other connection sockets are known. In known connection sockets generally exist elements of contact made in the form of sheets that extend in shape of Arc. When a plug is plugged into the connection socket, it comes into contact with the transition point of the element of arc-shaped contact The dimensions are chosen so that the plug, acting against an elastic antagonistic force, warps the sheet flattening its curvature. Therefore, the sheet is pushed with said elastic antagonistic force in direction radial against the push connector. In case the plug is move inside the plug connector transversely with respect to the insertion direction, there is always at least one sheet on which a minor deformation force acts, so The clamping force is also reduced. When the displacement of the plug inside the socket is large, it may even happen that the sheet detach from connector sleeve. Therefore, the DE-AS 1 042 137 provides that the sheet is housed floatingly, that is, so that it can be moved in radial direction.

The object of the present invention is perfect the connection socket that makes the document known DE-AS 1 042 137 so that a force is maintained of sufficient contact also when the plug is displaced transversely in the connection socket.

According to the invention, said objective is achieved. with a connection socket according to claim 1. The advantageous configurations of the concept of the invention are subject of the dependent claims.

Thanks to the clamping device provided according to the invention ensures the electrical contact of the elements of contact with a possible wiring of the connection socket, but it maintains the floating housing of the sheets or elements of contact, advantageous for contact with the plug. Thanks to that, in case of transverse displacement, the element of contact can follow the plug keeping at least the as much as possible, the antagonistic force necessary for the contact, so that sufficient contact is always ensured. In particular, the plug connection is charged in a Great symmetric measure.

Preferably, the contact element according to The invention is in the form of "V".

It is expressly stated that said "V" does not must necessarily be very sharp, and that both arms of the "V" also do not need to be straight but instead can have a curved shape, similar to that of the letter "C".

According to the invention, the first final section it can be formed on a first arm of the "V" and the second final section as well as the contact area may be in a second arm of the "V".

According to an embodiment especially preferred of the invention, the second arm of the "V" can be turn towards the first arm against an antagonistic force elastic

In other words, the insertion of the plug in the connection socket it causes the second arm of the "V" towards the first arm. When the material and dimensions are suitable, that turn is exclusively in the region of elastic deformation, and no plastic deformation occurs.

Additionally or alternatively, you can also provide that the first arm of the "V" can be turned against a antagonistic force radially outward around the First final section.

In this case the explained applies previously, that is, when the material and dimensions are suitable, also this turn is exclusively in the region of elastic deformation

You can ensure there will be a contact sufficient electrical, also when the plug is very displaced with respect to the connection socket, especially if the turn is used of the two arms towards each other as well as the rotation of the first arm around the first final section to generate the force antagonist that produces contact.

According to another preferred embodiment of the invention, it can be provided that the contact area is configured in the area that joins the two arms of the "V".

Preferably, the two arms are turned one towards the other, against an elastic antagonistic force. That is to say, that the "V" is under previous tension in the direction of the opening angle reduction. This previous tensile force is useful to configure even more securely the electrical contact of the contact elements with a possible wiring of the socket Connection.

According to an embodiment especially preferred of the invention, the junction zone of the "V" can be move radially outward against an antagonistic force elastic

With this configuration, this force elastic antagonist serves to make contact when Insert a plug into the connection socket.

Preferably, according to the invention, in this case is especially simple, from a mechanical point of view, that the clamping device exert an antagonistic force elastic contrary to the first and / or second final sections being detach from the contact surface.

According to the invention, it is also preferred that This clamping device comprises a spring.

It is also preferred according to the invention that the clamping device rests, on the one hand, on the first final section or on the second final section and, on the other hand, About a counterport

With this configuration you can use the clamping device for the conduction of electricity, in special when the device is conductive and the back support is a track for the current to be transported.

Preferably, the connection socket It comprises at least two contact elements, surrounded radially by an outer elastic ring.

It is expressly stated that this ring does not It must necessarily be circular. Instead, you can have other different geometric shapes, for example, an oval shape or elliptical

However, the elastic ring serves in all the cases to generate the aforementioned antagonistic force when the contact zone moves radially outward.

Since with this configuration a closed contour, that is said elastic ring, no need for no additional counter support for antagonistic force elastic, so it is no longer necessary to fix the elements of contact in the socket. Instead, contact elements can be housed "floating" in the socket, at least in Regarding your ability to move radially. Thank you to this, the force available to make contact between the contact elements and the plug is totally independent of any radial displacement of the plug inside the socket of Connection.

Preferably, the contact element according to The invention is a sheet.

In addition to the connection socket, the invention it also creates a plug connector consisting of a plug and a connection socket, as described before in detail.

Finally, it is preferred according to the invention that an introduction opening of the connection socket is dimensioned so that the plug is inserted loosely radial.

In this way the plug can be moved radially with respect to the connection socket, which is very advantageous For many applications.

The following is explained in more detail additional the invention, based on an exemplary embodiment and with reference to the attached drawing. The figures show:

- Figure 1 is a schematic section of a first plug connection not configured according to the invention;

- Figure 2 is a schematic section of a second plug connection not configured according to the invention;

- Figure 3 is a schematic section of a exemplary embodiment of the invention;

- Figure 4 is a top view of the example of embodiment of figure 3, but without the plug; Y

- Figure 5 is the same as Figure 3, but in Other operating status.

The plug connection shown in Figure 1 It comprises a plug (10) and a connection socket (12). The socket connection (12) has a bearing element (14) and a bushing (16). Other components of the connection socket are numerous sheets, of which only two are shown as an example in the figure 1. One of them is designated with the numeral (18). Each sheet it has a first final section (20) on a first arm (22) and a second final section (24) in a second arm (26). Both arms (22) and (26) are linked together by a junction zone (28). Next to the second final section (24) has been configured in the second arm (26) a contact zone (30), which enters Contact with the plug.

On the left side of figure 1 is shown the plug (10) inserted into the connection socket (12) in a centered position with respect to the insertion opening (32).

On the right side of figure 1 a operating state in which the plug (10) is displaced to the left with respect to the insertion opening (32). Correspondingly, the two sheets are also displaced (18) and (34). In particular, the second final section (24) of the sheet (34) left is shifted to the left. The same applies to the sheet (18) on the right side.

The left sheet (34), as a result of pin displacement (10), is rotated inside the opening insertion (32), counterclockwise, around its first final section (20). In addition, both arms (22) and (26) have approached each other.

In the sheet (18) shown on the side right, there has been a reciprocal deformation. The blade (18) still in contact with the outer jacket of the plug (10) With enough strength. Since the second final section (36) of the sheet (18) can be moved radially, the entire sheet (18) you can follow the movement of the plug (10), towards the left in figure 1, and ensure an electrical contact enough with the plug (10).

In the configuration according to figure 2, the zones of contact (38) and (40) of the sheets (42) and (44) are not close to the corresponding final sections, but rather in the area of union between the two arms (46), (48) or (50), (52). He bearing element (14) and bushing (16) push towards each other the two sheets (42) and (44) in axial direction against a force elastic antagonist, which leads to reliable contact for transmission of electrical signals of the sheets (42) and (44) with the bearing element (14) and the bushing (16). On the other hand, both sheets (42) and (44) and, especially, their final sections (54), (56), (58), (60), can be moved radially relative to the bearing element (14) and the bushing (16). An elastic ring (62), which expands against its elastic antagonistic force when Insert the plug (10), it serves to press the blades (42) and (44) on the plug (10). Thanks to that, the contact force it is totally independent of a transverse displacement of the plug (10) inside the insertion opening (32). How I know it follows from the joint observation of the two sides of the figure 2, the relative position of the plug (10) with respect to the blades (42) and (44) when the plug moves transversely with respect to the insertion opening (32), nor modifies the state of the two sheets (42) and (44), apart from their transverse displacement

The configuration shown in Figure 3 is very similar to the one in figure 2, so then only They will indicate the differences.

The contact areas (64) and (66) of the sheets (68) and (70), although they are not close to the corresponding ones final sections (72), (74), (76) and (78) of the arms (80), (82), (84) and (86) of the sheets (68) and (70), are not in position either symmetric In contrast, the arms (80) and (84) are shorter than the arms (82) and (86). However, the "V" shape materializes because the contact areas (64) and (66) are located in the corresponding points of the "V". Especially the arms (82) and (86) are not straight but curved in an arc.

However, as indicated above, it "V" means a configuration comprising a contact area located radially as far as possible with respect to to the blade.

Another difference between the configuration according to the figure 3 with respect to that of figure 2 is that a spring (88) that rests, on the one hand, on the final sections (74) and (78) of the sheets (68) and (70) and, on the other hand, on a inner surface (90) of the bushing (16) that serves as counter support Since the spring (88) is a pressure spring, the final sections (74) and (78) of the sheets (68) and (70) are reliably press against an inner surface (92) of the bearing element (14) serving as a contact surface, with It ensures a reliable electrical contact. To this contact electric contributes the fact that also the spring (88) is of a conductive material (for example, steel), so that it can also pass current through the spring and the bushing (16).

Same as antagonistic force based on own elasticity of the sheets (42) and (44) of Figure 2, also the spring (88) according to figure 3 allows the movement cross section of the plug in the connection socket while maintaining the electrical contact.

In the operating state that shows the Figure 5, the plug (10) is shifted to the left with respect to the operating state according to figure 3.

Also in the configuration according to figure 1, can provide a ring corresponding to the ring (62), specifically, for example, on the outer side of the area of contact (30).

As a summary it is pointed out that the connection socket according to the invention, as well as the plug connection according to the invention, allow transverse displacement of the plug with respect to the connection socket, without damaging the contact electric.
