Description

Visual signal MDR connector Technical Field The invention relates to the technical field of electrical equipment connectors, in particular to a visual signal MDR connector. Background The MDR (MINI DELTA rib) connector, which is a high-density and miniaturized Ribbon cable connector, is widely applied to the fields of industrial cameras, medical imaging equipment, machine vision systems, high-speed data acquisition and the like due to its excellent signal transmission performance and compact structural design, and particularly, in the occasion of transmitting high-speed visual signals, has raised higher requirements on the signal integrity and anti-interference capability of the connector. The MDR connector in the prior art generally adopts a conventional plug-in contact structure, that is, after the male head is inserted into the female head, electrical connection is achieved through elastic contact between the pins on the terminal block and the contact pads. This structure has the following problems in practical application: The contact stability is insufficient, namely, the pins and the contact plates generate contact pressure only by virtue of self elastic deformation, so that poor contact or instant disconnection easily occurs when the device is subjected to vibration or impact during long-term plugging and unplugging, a certain contact pressure is required to be maintained between the pins and the contact plates to ensure the contact reliability, the plugging resistance is increased due to overlarge contact pressure, the contact surfaces are easily worn, the service life of the connector is shortened, and the stability of signals is difficult to ensure due to overlarge contact pressure. The locking mechanism is separate from the contact mechanism-conventional MDR connectors typically provide a separate locking mechanism (e.g., a snap, screw, etc.) for securing the male-female connection, while the maintenance of contact pressure is entirely dependent on the elasticity of the terminals themselves. The separated design causes that a user cannot intuitively sense whether the contact is in place, and misjudgment of 'locked but not fully contacted' or 'good contact but unlocked' easily occurs, so that the reliability of connection is reduced. Therefore, there is a need to provide a novel MDR connector with reasonable structural design, reliable contact, stable locking, and convenient assembly and maintenance, so as to meet the severe requirements of high-speed visual signal transmission on the performance of the connector.
