Modular toy construction system connectors

A modular toy construction system comprising a first construction element and a second construction element, the first construction element comprising a first connector and the second construction element comprising a second connector, the first and second connectors being configured for connecting the first and second construction elements to each other in a coupling direction,

• wherein the first connector comprises at least two pairs of connector surfaces, where the two connector surfaces of each pair of connector surfaces are formed in parallel to each other,
• wherein the connector surfaces of one of the two pairs of connector surfaces on the first connector are formed at an angle relative to the connector surfaces of the other of the two pairs of connector surfaces on the first connector,
• wherein the second connector comprises a receiving part having a cross-sectional shape relative to the coupling direction, mating with a cross-sectional shape of the first connector, and configured for receiving and connecting to the first connector in a pressure fit with the connector surfaces of the first connector,
• wherein the receiving part of the second connector comprises a set of carrier surfaces each carrier surface being configured to be adjacent to and facing a specific one of the connector surfaces on the first connector, when the first connector and the second connector are connected to each other,
• wherein a set of functional surfaces is formed on at least one of the carrier surfaces of the receiving part of the second connector,
• wherein each functional surface is formed as a top surface of an island and elevated above the carrier surface, and
• wherein at least one of the functional surfaces is a pressure surface, the pressure surface configured to provide a deformation of a connector surface of the first connector.

A modular toy construction system comprising:

• a first construction element including a first connector having one or more connector surfaces;
• and
• a second construction element including a second connector having a receiving part;
• wherein the receiving part includes at least one elevated island having a pressure surface, the pressure surface being configured to engage and deform at least one of the connector surfaces of the first connector when the first and second connectors are coupled in a pressure fit.
