Description

The present invention relates to a connector socket, and a board-to-connector connector and a board-to-board connector.

When a printed circuit board is connected to a plug or to another printed circuit board, forces can be produced on the soldered connections of the printed circuit board during a relative movement of the printed circuit board relative to the plug or the further printed circuit board. If these forces are great, the solder joints may break. So far, this problem has been solved by means of multi-part decoupling configurations, which reduce the forces acting on the solder joints in the relative movement. However, such multipart decoupling configurations are expensive and expensive to manufacture and assemble.

The present invention has for its object to provide an easily manufactured and assembled connector socket that connects two boards or a board with a connector such that damage to the board due to relative movement of the board relative to the connected board or against the plug are avoided. It is another object of the present invention to provide a corresponding board-to-plug connector and a corresponding board-to-board connector.

According to one aspect of the present invention, there is provided a connector receptacle having a connector main body and a plurality of contact members, wherein a plurality of male contact receiving portions are formed in the connector main body, the plurality of contact members each having a terminal portion and a contact portion, the terminal portion being to electrical connection with an associated board contact of a board, and wherein the contact section is arranged in an associated plug contact receiving area of the connector socket for electrical contacting with a complementary plug contact, and wherein the terminal sections and the contact sections of the contact elements are each elastically displaceable against each other, so that in the connected state of the terminal portions with the board contacts of the connector main body with respect to the board is elastically displaced.

Advantageously, the configuration according to the invention is suitable for installation in devices whose individual components have frequent or steady relative movements to each other, for example due to vibrations and / or shocks and / or other forces, such as occur during operation of a motor vehicle. The configuration according to the invention avoids damage to a circuit board in a simple manner, which during operation performs relative movements with respect to a connected circuit board or with respect to a connected connector, without it being necessary to provide a complicated multipart decoupling configuration.

The connector main body of the connector socket has a plurality of male contact receiving areas, wherein the male contact receiving areas may be arranged one, two or more rows next to each other. By way of example, the connector main body of the connector socket 16 may have male contact-receiving portions arranged in two rows, whereby this connector main body thus has 8 male contact receiving portions in the length and 2 male contact receiving portions in the width. The connector main body may be formed of an electrically non-conductive material such as plastic.

The male contact receiving areas of the connector main body may each be assigned to a contact portion of the plurality of contact elements, i. In each plug contact receiving area, in each case a contact section of a contact element arranged on the corresponding plug contact receiving area can be arranged. The male contact receiving areas may each be formed with an axial and a radial extent and be formed as in the axial direction by the connector main body extending cavity. The male contact receiving areas may have a substantially square, rectangular, circular or oval cross-section transverse to the axial direction. However, the male contact receiving areas may also have a different shape.

For a better spatial understanding, the spatial arrangement of the connector socket, in particular of the connector main body and the plurality of contact elements, will be described below, partly in relation to an assignable board, with the board contacts of which the connection sections of the contact elements are to be connected.

The male contact receiving areas may be arranged in the above-described axial direction orthogonal to a board plane in which the associated board is arranged, whereby the male contact receiving areas each have a side facing away from the board and a side facing the board. In other words, the extension axis of the plug contact receiving areas may be substantially perpendicular to the board plane formed by a width and a length of the board. The connector socket and the connector main body, respectively define a longitudinal, a width and a height direction, wherein the height direction may be aligned orthogonal to the board plane and may correspond to the extension axis of the plug contact receiving areas. The cavities of the plug contact receiving areas may each be designed to receive and connect an associated complementary plug contact of a plug.

In order to receive the complementary plug contact, two openings can be formed by means of the cavities in the plug contact receiving areas, namely an opening on the upper side of the plug contact receiving areas facing away from the printed circuit board and an opening on the lower side of the plug contact receiving areas facing the printed circuit board. The inclusion of the complementary plug contact is then carried out by inserting the plug contact into the cavity of the respective plug contact receiving area through the opening on the side facing away from the board of the plug contact receiving area. The opening may be congruent in radial extent with the radial extent of the cavity, i. the opening and the cavity may have the same diameter. Alternatively, the opening may also be larger than the cavity and extend from a surface of the connector main body approximately conically tapered toward the interior of the plug contact receiving area until the radial extent of the cavity is reached. As a result, a funnel-like shape can be formed, which guides the insertion of the plug contact into the cavity of the plug contact receiving region through the opening along the funnel in the direction of the cavity.

The complementary plug contact of the plug can be formed such that it fills the cavity of the plug contact receiving area accurately, so that the complementary plug contact is held after insertion into the cavity of the plug contact receiving area. The complementary plug contact may be formed on a plug which is electrically connected to a wiring harness of a motor vehicle. The plug can have so many plug contacts that each plug contact receiving area of the connector socket exactly one complementary plug contact can be assigned. The plug contact can be dimensioned in its length exactly so that a contact to a contact portion within the cavity can be produced.

The connection or the production of an electrically conductive contact can be effected by contacting the complementary plug contact with the contact section of a contact element. For this purpose, a contact element belonging to the plug contact receiving area can be arranged on the plug contact receiving area such that the contact section of the associated contact element protrudes from the side of the plug contact receiving area facing the board into the cavity of the plug contact receiving area, whereby in the inserted state of the plug contact receiving area complementary plug contact a physical or electrically conductive contact can be produced.

By the contact portion of a contact element may be meant the portion of a contact element which is formed for electrical contacting with an associated complementary plug contact of a plug. By the terminal portion of a contact element may be meant the portion of a contact element which is formed for electrical connection to an associated board contact of a board. The contact portion and the terminal portion may each be formed at an end portion of the contact member.

The contact sections and the connection sections of the contact elements can each be formed as a widened region of the contact element. The connection section can be formed, for example, as a broad base, which can be connected to a board contact of a board with a solder connection, whereby a sufficiently large soldering area can be ensured. The terminal portion may also have other shapes. For improved solderability of the stand may have recesses can emerge through the solder melt during soldering of the connection portion with a board contact, whereby an improved fixation of the contact element is achieved.

The contact portion may be formed as a widened area corresponding to the diameter or dimension of the cavity or opening of an associated male contact receiving area, whereby a sufficiently sized physical or electrically conductive contact between the contact portion and a complementary male contact of a plug can be produced , Alternatively, the contact portion may be formed in another shape, such as an extending in the direction orthogonal to the board plane in the plug contact receiving area extending portion, which is bent back by means of a bending portion such that approximately a V-shape or hook shape within the plug contact receiving area is formed, wherein a V-leg is not orthogonal to the board plane. The V-shape can extend over the entire diameter of the cavity or only over a partial area. The bending section can be formed at one end of the contact section and form a resilient contact point.

Starting from a widened region of the contact elements, for example the connection section, a substantially wave-shaped section can extend towards the contact section. The contact portion may extend from or be formed as part of this end from the other end of the wave-shaped portion, the contact portion extending into an associated male contact-receiving area of the connector main body. The substantially undulating portion may have, similar to a hairpin, two long, straight portions which are connected by a bending portion such that the two long straight portions are substantially parallel to one another. The straight areas may extend essentially in the height direction of the connector main body, that is to say substantially orthogonal to the board plane. The wave-shaped portion may include one, two or more of these hairpin-like portions connected to bending portions, respectively. The bending sections may be formed approximately U-shaped. Alternatively, the wave-shaped portion may also have a substantially V-shaped configuration, with two long, straight portions, which are connected by means of a bending portion such that the two long, straight portions extend substantially V-shaped side by side, and not parallel. The bending sections can be formed approximately V-shaped, or as a U-shape with diverging U-legs.

The contact elements can be flat, that is to say in each case lying in one plane (that is to say lying in a contact element plane). This contact element plane of a contact element may be orthogonal to the board plane. The contact elements can be punched directly from a sheet. It is also possible to punch strip-shaped parts from a sheet and then to bend them about a width axis of the parts to form a contact element. The contact portion and the terminal portion may also be formed by bending. Along the extension direction of the contact element, the contact element, for example, the region between the connection portion and contact portion, a slot may be formed. This can advantageously increase the mobility of the contact element sideways or increase the elasticity of the contact elements when a sideways directed force occurs. By "sideways" is meant a direction which is parallel to the board plane and in particular corresponds to the longitudinal direction of the connector socket. Each contact element may have two or more of these slots, which may be formed parallel to each other.

In a connected or soldered state of a connection section of one of the plurality of contact elements with an associated board contact of the board, the contact element may at least partially extend at right angles to the board. A plurality of board contacts can be arranged on the board such that, in the connected state of the plurality of contact elements with the board contacts of the board, the contact elements are arranged at least in sections approximately at right angles or orthogonal to the board, the respective contact element planes being parallel to one another can. At the connector main body, the contact portions of the contact elements may be aligned in parallel with each other and extend into an associated male contact-receiving area, respectively. If the plug contact receiving areas of the connector main body are arranged in two rows parallel to each other, then two contact elements may be spaced apart from one another and located opposite one another in a common contact element plane. The contact portions of the two contact members may face each other and extend into respective one of a corresponding male contact-receiving area of the double-rowed connector main body. The two plug contact receiving areas can be arranged on the contact element level between the two contact elements, wherein in each plug contact receiving area in each case a contact portion of the contact elements extends. These embodiments may be applicable with appropriate changes for the other alternatives described above.

In other words, the contact elements may each be arranged in pairs, opposing to the connector main body, wherein the contact portions of the two contact elements each extend into an associated plug contact receiving area, and wherein the plug contact receiving area of a common plane of the two contact elements are located. The common plane of the two contact elements may be arranged orthogonal to the board plane of an associated board.

A plurality of pairs of contact elements arranged in this way can be arranged on the circuit board, the pairs of contact elements being arranged approximately parallel to one another and each of the contact sections of the contact elements extending into an associated plug contact receiving area. The connector main body may be disposed between the paired contact elements such that the connector main body is supported by the board "floating" from the contact elements, in particular, only "suspended" over the board by the contact elements.

The board contacts can be arranged on the board such that each board contact can be electrically conductively connected to an associated terminal section of a contact element of the plurality of contact elements. The number of board contacts can correspond to the number of contact elements. The board contacts may be connected to tracks on the board, wherein the board may be connected to a component of a motor vehicle. The board contacts may be solderable areas that are formed for mechanical attachment and electrical connection of the contact portions of the contact elements.

The plurality of contact members of the connector socket may correspond to the number of the plug contact receptacles of the connector main body for disposing a contact portion of a contact member of the connector socket in each male contact receiving portions, the male contact receiving portions being formed to make electrical contact with a complementary male contact. For this purpose, the contact elements can each be arranged in a region on that plug contact receiving area in which the contact portion of the contact element can be arranged.

In the connector main body described above by way of example with 8 male contact receiving areas in length and 2 male contact receiving areas in width, the contact elements may also be arranged in two rows of 8 contact elements each, one contact element in one area on the male contact receiving area.

The plurality of contact elements may be formed of an elastic, conductive material, for example of a conductive spring steel, and may act as spring elements. The contact elements may be positively or positively connected to the connector main body by means of insertion portions arranged on the connector main body, in each of which a contact element is inserted or inserted. When the terminal portions of the contact members are connected to the board contacts of a board, and a force acts on the connector main body or a portion of the contact members, the connector main body of the connector socket may be elastically displaceable against the board.

The connector main body may be displaced in all directions, that is, sideways (ie, longitudinally and / or widthwise) and / or vertically from a rest position in which the connector main body is free from a force, and may be displaced after the decay of the displacing Force due to the elasticity of the contact elements return to its rest position. By "sideward" and "height direction" is meant the directions in which the board or connector main body also extends in length, width and height in space. That a movement along the length of the board (the longest dimension of the board) or along the width of the board (the second longest dimension of the board) is "sideways". A movement along an orthogonal axis to the plane formed by the width and length of the board (the board plane), ie the height of the board (the shortest dimension of the board) is a movement in the height direction. In other words, the connector main body, which is connected to the board by means of the plurality of contact elements, can have at least three translational degrees of freedom relative to the board. Also, 1, 2 or 3 rotational degrees of freedom can be provided. The mobility of the connector main body relative to the board may be limited to a predetermined range of movement by stops on the connector main body. The mobility of the connector main body to the board or the contact portion to the terminal portion may also be referred to as "game".

The elasticity of the plurality of contact elements is set such that upon elastic displacement of the connector main body against the board, the connection of the terminal portions of the contact elements with the board contacts of the board, for example a solder joint, is not damaged and no plastic deformation of the contact elements occurs. In addition, during or after the displacement, the electrical conductivity of the connection of the terminal sections of the contact elements with the board contacts of the board remain unaffected.

Preferably, the contact elements each have a substantially wave-shaped section between the connection section and the contact section.

Advantageously, an increase in the total length of the contact element can be achieved by means of the wave-shaped formation without substantially increasing the space requirement. With an increased overall length, the elasticity of the contact elements can be adjusted or increased.

Preferably, the undulating portion comprises a plurality of turns, wherein the dimension of a turn in the height direction is greater than the dimension of the turn in the width direction.

Advantageously, a greater overall length of the individual contact elements can be achieved by a plurality of turns in a relatively small space. With a larger one Overall length of a contact element is a greater spring distance for an elastic deformation available, whereby the amount of deflection increases by which a displacement can be elastic without exceeding the elastic limit of the material used. Spring steels can be used as material. By winding may be meant the aforesaid hairpin-shaped portion of a contact element having two long, straight portions connected by a bent portion.

Preferably, the dimension of a turn in the height direction is between 10 mm and 40 mm, preferably between 20 mm and 35 mm, and wherein the dimension in the width direction is between 5 mm and 15 mm, preferably between 8 mm and 12 mm.

Preferably results in the connected state of the terminal portions with the board contacts by the elastic displacement game for the connector socket, which in the range of +/- 1 mm to +/- 3 mm, preferably in the range of +/- 1.5 mm to +/- 2 mm.

The resulting clearance refers to the amount by which, in the connected state of the terminal portions, with the board contacts of the connector main body, it can elastically shift with respect to the board. That is, starting from the rest position of the connector main body, it can be displaced in one direction or the other by the amount of play without damaging the connections and without causing plastic deformation of the contact elements.

Preferably, at least one stopper is formed on the connector main body to limit a displacement of the connector main body with respect to the board in the connected state of the terminal portions with the board contacts.

The stopper may extend from the connector main body to the board and allow as much room for a displacement of the connector main body toward the board that the plurality of contact elements are protected from contact with the board by the stop. Alternatively or additionally, the stopper may also be configured to limit movement of the connector main body in the longitudinal direction and / or in the width direction of the connector main body.

Advantageously, the stopper in the manufacturing process may be manufactured together with the connector main body of the connector socket by means of an injection molding method. In addition, the plurality of contact elements can be connected to the connector main body by means of an in-mold method, whereby the production of the connector socket is extremely simple and inexpensive to carry out. Other manufacturing methods are also possible.

Thus, an electrical conductive connection between the board and the plug is provided in which the connector main body is elastically displaceable with respect to the board, whereby any pressure or shear forces acting on the board-plug connector, are cushioned. The plug can be electrically connected to the wiring harness of a motor vehicle. Likewise, the board may be part of a component in a motor vehicle.

The guide pins may further be formed so that they themselves each fulfill a plug-in function and engage in complementary guide portions, which are arranged for example on the connector socket, whereby during assembly of the board-board connector, the connection of the plug contacts of the plug unit with the plug contact receiving area the connector socket is feasible.

Preferably, the plug unit has a plurality of contact element recesses in which the contact elements of the connector socket can be received at least in some areas in order to prevent the contact elements from contacting one another.

The contact elements of the connector socket can get into vibration during relative movements of a component connected by means of a printed circuit board or a plug, whereby the danger exists that the contact elements come into physical and / or electrical contact with each other. This contact is avoided by means of Kontaktelementausnehmungen, whereby the contact elements can be arranged close to each other despite high elasticity. Preferably, a region of the contact element between the connection section and the contact section, which projects the most during vibrations, can be accommodated in the contact element recess.
