Description

Plug connector

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a plug connector, and more particularly to a plug connector that is in direct contact with a circuit board. In addition, the present invention is particularly directed to a plug connector that can be plugged in with less force, which is higher in the plugged state. Keep the strength.

Plug connectors are often used, such as connecting two wires to each other in a reproducible manner, or connecting a wire to an electronic device. In the latter case, for example, the plug connector can be a case. The body member, or housing, has a suitable opening or recess to receive the side of the plug connector toward the wire.

The contact elements of the plug connector must be able to contact each other with certainty. The joint transition position is mostly achieved by the two metal faces leaning against each other, for example, a conductive contact spring rests on a conductive contact surface.

Therefore, in such a plug connector, the quality of the plug (ie, the contact condition of the two contact elements) is at least affected by the contact force. For example, in the case of a spring contact element resting on a metal surface, the quality of the plug is from the normal force acting on the contact surface by the spring point element. Thus, the use of a suitable normal force prevents the plug contacts or conductive contacts from providing a poor connection, particularly a poor conductive connection.

A special kind of plug connector is a so-called "circuit board direct plug connection" Here, a contact component of the plug connector is directly composed of an electrical component (for example, a conventional electronic circuit board or a printed circuit board (PCB)), and contact with a component provided on the circuit board is available. Caused by a conventional conductive path on the surface of the board component or inside. The contact surface of a plug connector can be directly formed as an area on the surface area of the board that can be probed.

In a conventional circuit board, a connector is directly plugged, for example, an external contact element (for example, a spring contact) is provided on the conductive contact surface or the so-called "land", and a leaning force is used there. Or the normal force to keep the contact elements in conductive contact. For example, in a plug-in process, a contact component is raised first, and then moved to a "board directly plugged connection component" and then lowered or leaned onto a circuit board or a "land". Generally, in addition to a leaning force, a normal force can refer to the compressive force or contact force between two contact elements.

Due to the physical size of a circuit board component, on the one hand, when a contact component is plugged through the edge of the circuit board, the contact point of the contact component to be inserted is damaged. In addition, however, it is desirable for the contact elements to have a frictional motion on the "land" of the board to remove possible foreign objects or to penetrate the oxide layer that may form.

In the conventional joint, the force required for the insertion, and the force acting at the final position (normal force) are caused by the fitting of the mutually fitting members (for example, by the slope of a slider), so it is difficult to use a measurement. The tolerance field (Toleranzfeld, English: tolerance field) is indicated.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a plug connector, particularly a circuit board direct plug connector, which utilizes a smaller plug strength for more reliable contact.

The scope of the patent application of the present invention is a plug connector, a control device for a car, and a car (particularly a car). Further features are found in the application Scope of the subsidiary.

According to the invention, the required plugging force can be applied irrespective of the normal force during the insertion process.

Therefore, the plug strength is mainly caused by the geometrical properties of the contact element or the spring contact element and the circuit board directly plugging the connection element, with appropriate geometry, for example, the contact element rests on the other contact element The power can be reduced during the docking process. Subsequently, the extension to the final position, by means of appropriate means to apply a general or additional force, after the insertion process, overlap or add to the existing existing leaning force, so that the contact force between the two contact elements or The power of the law is increased.

In other words, the plugging process of the plug connector can first cause the relieving force to be uncertain throughout the operating state to ensure a true contact. Therefore, the leaning force F _A can be regarded as the force that is adjusted between the contact elements after the contact. In order to ensure that the contact elements are indeed in contact, another element can be placed in the plug connector, thus creating an additional force F _Z and overlapping or adding to the leaning force F _A such that the docking state relies on the force F _A . Therefore, in the final plug-in state, the total dependence force F _ges =F _A +F _Z .

Accordingly, in accordance with the present invention, a means for reducing the labor involved in plugging is provided, wherein the contact force can be increased with appropriate components after the docking process. Thus, for example, after the engagement of the contact elements of the plug-in element, that is to say after sliding with a force (which is produced by the slider of the plug connector), for example, with an operation, A component or a lever (which is used to make the insertion easier) relatively moves a force element and an opposing force element, so that the contact element has a greater compressive force acting on the other contact element.

The force element and the opposing force element can be designed as a pair of ramps, for example. In this case, the paired ramps can increase or decrease the total height of the two ramp elements in the other direction (for example, perpendicular to the moving direction) by moving the two ramp elements, so that the leaning force can be used during the plugging process. It is adjusted independently of the normal force acting in the docking state. Thus, for example, the contact surface of a contact member or its "land" may be prevented from being damaged by too much friction without affecting the actual electrical contact action at the time of use. Conversely, the reclining force or normal force is generated at the end of the docking process by the relative movement of the ramp or similar guide. The resulting contact force is caused by the resulting compression. For example, this force may also utilize the force element and appropriate design constraints on the steepness of the separate elements of the main force element.

A sealing element (e.g., a sealing mesh) can additionally seal a housing opening. Here, the force element or the opposing force element can also be actuated by the sealing element (for example a sealing net). The force element and the opposing force element can, for example, be rounded in a round or similar element and designed to move through the sealing net. It is also conceivable to effect the movement of the insertion and the action of the force element and the opposing force element via other action elements (for example the rod) with a lever itself in the plug connector.

Therefore, a plugging motion is finally caused, and the contact elements are appropriately positioned relative to each other with a small leaning force, and in the continued insertion movement, the force element and the opposing force element are relatively displaced substantially, and a larger leaning is provided. power.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic top view showing an exemplary design of a plug connector according to the present invention; and Fig. 2 is an illustration of a plug connector insertion process according to the present invention.

Figure 1 shows a schematic cross section through a plug connector (2) of the invention. At least one first contact (4) (in the example of Fig. 1, two first contact elements (4a) (4b)) are disposed around a second contact element (6) (designed as a circuit board).

The second contact element (6) has a contact surface (6a) or "land" which is electrically connected to the first contact element (4a) (4b). The contact surface (6a) can be connected to the electronic components within the housing on the surface or inside of the board in a suitable manner. At the first contact element (4a) (4b). For example, a wire connector or the like is connected for electrical contact conduction. The plug connector (2) may also have a plurality of first and second contact elements, for example, which extend at a distance from the plane perpendicular to the drawing.

On the side of the first contact element (4a) (4b) opposite the second contact element (6), for example, a force element (8) and an opposite force element (10) are provided (10a) ). In the example of Figure 1, the opposing force element (10) consists of a housing (10) having an element (10a) that is inserted or integrally formed. If this is not the case, the housing (10) can be directly in the shape of this ramp of the component (10a).

The force element (8a) (8b) is designed in the form of a triangular ramp coming from the open side of the plug connector (2). Put it inside the plug connector. Since the force member (8a) (8b) and the opposite force member (10a) (10b) are inclined at the side, when the force member (8a) (8b) is pushed in (the movement to the right in Fig. 1 (12a)] The total height of the force element (8a) (8b) and the opposing force element (10a) (10b) is increased. Due to the increase in height, a resultant force acts from the force element (8a) (8b) to the two first contact elements (4a) (4b). Therefore, it is pushed in properly by the force element (8a) (8b). The two first contact elements (4a) (4b) act on the second contact element (6) or its contact surface (6a) with a large rest or contact or normal force.

In other words, an added force (12a) is converted to the direction of force action (12b) in the case of using the force element (8a) (8b). For example, force (12a) (12b) acts perpendicular to each other.

For example, a sealing element (14) is provided to open the plug connector (12) The mouth seal is provided with contact elements in the plug connector, which are not fixed.

In addition, please refer to Figures 2a-2c, which show the plugging process of the plug connector of the present invention.

In Fig. 2a, the first contact element (4a) is located on the second contact element (6) or its land (6a) during a plugging process. In this case, the deformation force of the point element (4a) is applied by means of the second contact element (6) or its contact surface (6a). The contact element (4a) rests on the contact surface (6a) of the second contact element (6) with the resting force F _A . A force element (8a) is provided between the first contact element (4a) of the plug connector (2) and the housing (10) (10a), but is still not pushed in the direction of the opposing force element (10a).

2b, the force element (8) at this time is a position in contact with the opposing forces while the element (10a) and a first contact member (4), without applying an additional force F _Z. For example, the small movement of the force element (8) is caused by the first contact element (4a) to the second element (6) after the positioning is completed, or the contact element (4a) and the force element ( 8a) may be designed such that the contact between the two sides is from the opposite force element (10a) and the first contact element (4a) by the force element (8a) at the end position of the first contact element (4a) to be occupied The two contact elements (6) are achieved.

In Fig. 2c, another motion acts on the force element (8) in the direction (12a), thus moving relative to each other due to the ramp configuration of the force element (8a) and the opposing force element (10a), thus an additional force _FZ Acting on the first contact element (4a) and the second contact element (6). Therefore, the _total force F = F _A + F _Z increases the initial contact force or the leaning force (increased additional force F _Z ). Therefore, relative movement in the direction (12a) by the force member (8a) and the opposing force member (10a) causes the initial leaning force F _A to increase in the docked state.
