Description

Power plug connector system
Technical Field
The utility model relates to a power plug connector system, wherein the contact surfaces of the contact elements can be brought into contact with elastic sheet elements in order to produce and break electrical connections under load.
The power plug connector system comprises: a contact element having at least one contact surface and at least one recess; and
a contact element having at least one elastic sheet element, wherein the contact element can be at least partially contacted with the elastic sheet element in a pushing direction, wherein a section which extends at least partially in the pushing direction and protrudes is arranged on a side of the elastic sheet element facing the contact surface, and a contact region is arranged behind the protruding section in the pushing direction.
Background
A power plug connector system in the form of a circuit board connector is described, for example, in DE 10 2012 021 615 A1. The described circuit board connector has a connecting element with a protruding section which engages in a contact state in a recess of the corresponding contact element.
EP 2 926 A1 also describes a power plug connector system having a contact element with a resilient sheet element on which a retaining device is arranged by means of a material impression.
In documents CN 203250889U, CN 107134693, CN 206640005U and US
Further examples of power plug connector systems are described in 10,581,196B2.
However, the solutions known from the prior art have the disadvantage that when the circuit is closed or opened, the generation and disconnection of the plug connection under load many times can increasingly damage the power plug connector system due to the occurrence of a power outage or spark, and thus reduce the product life.
Disclosure of Invention
The object of the present utility model is to provide a power plug connector system which enables an increased plug cycle under load and thus an increased product life.
This object is achieved by the power plug connector system according to the utility model.
The protruding section thus has a tear-off region (abrissbeerich) and a sliding region located behind the tear-off region in the push-in direction, wherein the tear-off region first contacts the contact surface in the push-in direction and the last contacts the contact surface in the pull-out direction, the sliding region contacts the contact surface during sliding in the push-in direction and the pull-out direction, and the protruding section is arranged at least partially in the recess in the push-in state and the contact region contacts the contact surface.
The power plug connector system may be arranged, for example, on a circuit board and/or on a wire and is suitable for closing an electrical circuit by plugging together contact elements and contact elements.
The contact element has at least one contact surface for this purpose. The contact element may also be referred to as a "contact blade" and has a connecting element, for example a connecting pin, with which the contact element can be electrically connected, for example, to a conductor track on a circuit board. For this purpose, the contact elements are generally composed of an electrically conductive material.
Furthermore, the power plug connector system has a contact element with at least one elastic sheet element. The contact element may also be referred to as a "contact tulip", is usually also constructed from an electrically conductive material and usually also has a connecting element, for example a connecting pin. The elastic sheet element may also be referred to merely as a "sheet" or "contact spring" and may be arranged on the contact element such that when the contact element is pushed in, it presses against the contact surface in order to contact at least one region of said contact surface. Thus, the "pushed-in state" herein may also be referred to as a "contacted state". The term "contacting" is understood here to mean electrical as well as mechanical contact.
On the side of the elastic sheet element facing the contact surface, a section is provided which extends at least in some areas in the pushing-in direction and protrudes, and a contact region is arranged behind the protruding section in the pushing-in direction.
The protruding section may be elongate and extend, for example, in the middle of the sheet element along the axis of the pushing-in direction. In examples, the protruding sections may be introduced into the material of the elastic sheet element by means of a stamp or manufactured by coating the material onto the material of the elastic sheet element. The protruding section may also be referred to as a "sacrificial area" because it is subjected to the strongest power outage or spark when making and breaking electrical connections under load.
The contact region is arranged behind the protruding section in the insertion direction, and in the inserted state, it is in contact with the contact surface.
The protruding section has a tear-off region and a sliding region located behind the tear-off region in the insertion direction, wherein the tear-off region first contacts the contact surface in the insertion direction and last contacts the contact surface in the removal direction. Thus, during the production and disconnection of the plug connection under load, the tear-off region is subjected to the strongest load and thus to the strongest wear. The removal direction may extend opposite to the pushing direction.
In one example, the tear-away region first contacts the contact surface in the push-in direction and last contacts the contact surface in the pull-out direction. At the rest of the time, at least no direct contact of the tear-off region with the contact surface is present during insertion and removal and in the pushed-in state. During movement in the pushing-in direction and/or the removal direction, only the sliding region can contact the contact surface.
In the pushed-in state, the protruding section is arranged at least partially in the recess, and the contact region contacts the contact surface.
As a result of the sequential arrangement of the tear-off region, the sliding region and the contact region on the elastic sheet element, a low-wear generation and disconnection of the electrical connection under load can be achieved and thus the product life of the power plug connector system configured in this way is advantageously increased.
In one example, the protruding section has a semi-cylindrical cross-section and the recess has a corresponding semi-cylindrical recess.
The term "semi-cylindrical" is also understood as "truncated spherical". Advantageously, contact can thereby be established over a larger surface area and wear can thereby be reduced.
In an example, the protruding sections may also be designed in other ways, for example in a dot-like or rectangular manner.
In one example, the recess is designed as a stamp.
Advantageously, the recesses can be introduced into the material of the elastic sheet element quickly and simply during the manufacturing process by means of a corresponding embossing tool.
In one example, the protruding section is configured as two-piece or multi-piece.
For example, the tear-away region and the sliding region may be separately configured in the material of the sheet element and may also have different geometries. For example, a two-part design can be selected, so that the requirements of the individual application areas can be better met.
In one example, the contact elements, in particular the contact surfaces and/or the contact elements, in particular the protruding sections and the contact areas, are coated with an electrically conductive material.
For example, the protruding sections, in particular the tear-off regions, may be coated with a mechanically resistant material and/or a material having a higher electrical conductivity than the material of the elastic sheet element. For example, the material may be selected from the group consisting of: copper (Cu), silver (Ag), gold (Au), platinum (Pt) or palladium (Pd).
In one example, the contact surface has a structured surface region, in particular a groove, at least in regions.
Advantageously, the contact can be improved by a structured surface region.
In one example, the elastic sheet member has a curved portion formed in the pushing-in direction. The curvature can be formed, for example, in an arcuate manner and advantageously enables a defined abutment of the elastic sheet element on the contact surface.
In one example, the contact element comprises a further contact surface with at least one further recess, the further contact surface being opposite to the contact surface, and
the switching element has a further elastic sheet element with protruding sections, which is opposite the elastic sheet element, wherein the contact element can be at least partially introduced between the elastic sheet elements.
For example, the switching element can thus have two elastic sheet elements of identical design. The two elastic sheet elements can be arranged mirror-image to each other on the connecting element and contact the contact surfaces on the opposite faces of the contact elements. When the contact elements are introduced between the elastic sheet elements, these sheet elements can first be moved away from each other by the material of the contact elements and then pressed against the contact elements with a defined force.
In one example, each of the two opposing contact surfaces has at least two recesses arranged side by side, and the switching element comprises two pairs of corresponding elastic sheet elements arranged side by side with protruding sections and contact areas.
Advantageously, product life may be increased by this configuration.
In one example, the end region of the contact element is at least partially divided into two surface sections in the insertion direction, and one of the two surface sections is configured in a shortened manner.
The term "partially divided into two parts" is to be understood as meaning recesses or elongated incisions in the material of the contact element, which divide the contact surface into two surface sections at least in the end regions.
Advantageously, one of the surface sections can be designed to be shortened relative to the other surface section in order to ensure that, during contact separation, i.e. when the contact element and the switching element are moved away from each other in the removal direction, the arc always ignites on the same surface section, while the other shorter surface section remains untouched.
