Description

Technical Field

[0001] This utility model relates to a connector, and more particularly to a D-type connector. Background Technology

[0002] D-type connectors are characterized by their metal shielding shell, which resembles the letter "D." Thanks to the foolproof positioning and mechanical strength of the shell, they have long been used in industrial control, instrumentation, communication equipment, computer peripherals, and aerospace. These connectors typically consist of a pressed or cast metal shell, an insulating body, several pin (hole) terminals, and a locking mechanism. Common terminal materials are phosphor bronze or brass, and surface plating options include gold plating, tin / nickel plating, etc., to balance conductivity, corrosion resistance, and cost.

[0003] The aforementioned existing technical solutions have the following drawbacks: traditional D-type connectors are difficult to operate stably for a long time in outdoor, dusty, high-humidity, or salt spray environments; even with the addition of a back shell or sheath, there may still be a problem of discontinuous sealing chains. Utility Model Content

[0004] The purpose of this invention is to provide a D-type connector to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A D-type connector includes a base, an insulating plate fixedly mounted on the top of the base, and first through holes symmetrically arranged at the left and right ends of the top of the insulating plate, with the axis of the first through holes being vertically aligned. A solid nut is riveted to the top of the insulating plate, the axis of the solid nut being collinear with the axis of the first through holes, and the bottom surface of the solid nut fitting against the top surface of the insulating plate. An integrally formed first rectangular ring protrusion is provided on the top of the insulating plate, with the axis of the first rectangular ring protrusion being collinear with the axis of the insulating plate. An integrally formed second rectangular ring protrusion is provided on the bottom of the base, with the axis of the second rectangular ring protrusion being collinear with the axis of the base. An integrally formed first rectangular plate is provided at the bottom of the second rectangular ring protrusion, with the axis of the first rectangular plate being collinear with the axis of the second rectangular ring protrusion.

[0007] By adopting the above technical solution, the axis of the solid nut is collinear with the axis of the first through hole, which can effectively avoid problems such as installation difficulties and thread damage caused by the deviation between the hole position and the nut center during the installation process. This significantly improves the convenience of assembly and the reliability of connection, and ensures the structural stability of the connector after installation.

[0008] In a further embodiment, the top of the insulating plate is uniformly provided with a plurality of first circular holes, the axis of the first circular holes is vertically arranged, the first circular holes are all located inside the first rectangular ring protrusion, and a terminal is fixedly installed in each of the first circular holes, the axis of the terminal is collinear with the axis of the first circular hole.

[0009] By adopting the above technical solution, when the terminal axis is collinear with the first circular hole axis, it can provide a clear and unique reference for the installation of the terminal in the first circular hole, ensuring that the terminal is accurately fixed in the preset position, effectively avoiding problems such as terminal tilting and offset caused by installation deviation, improving the convenience and accuracy of installation, reducing the installation difficulty and time cost, and the collinear axis allows the contact surface of the terminal to make uniform and sufficient contact when connected to external wires or other electrical components.

[0010] In a further embodiment, the front end face of the first rectangular ring protrusion is uniformly provided with a plurality of rectangular holes, the axes of the rectangular holes are all arranged front and back, and an integrally formed second rectangular plate is provided on the inner top of each rectangular hole. The bottom end of the second rectangular plate is offset into the rectangular hole, and there is a gap between the bottom end of the second rectangular plate and the bottom end of the rectangular hole.

[0011] By adopting the above technical solution, the existence of the gap forms an air circulation channel through the rectangular hole, which helps to dissipate the heat generated by the component during operation through convection, and avoids heat accumulation that affects the performance of the component. In addition, if foreign objects such as dust or liquid enter the rectangular hole in the equipment operating environment, the gap can serve as a discharge channel to prevent jamming or corrosion caused by the accumulation of foreign objects.

[0012] In a further embodiment, the rear end face of the first rectangular ring protrusion is uniformly provided with a plurality of rectangular holes, the axes of the rectangular holes are all arranged front and back, and the inner top of each rectangular hole is provided with an integrally formed second rectangular plate, the bottom end of the second rectangular plate is offset into the rectangular hole, and there is a gap between the bottom end of the second rectangular plate and the bottom end of the rectangular hole.

[0013] By adopting the above technical solution, the existence of the gap forms an air circulation channel through the rectangular hole, which helps to dissipate the heat generated by the component during operation through convection, and avoids heat accumulation that affects the performance of the component. In addition, if foreign objects such as dust or liquid enter the rectangular hole in the equipment operating environment, the gap can serve as a discharge channel to prevent jamming or corrosion caused by the accumulation of foreign objects.

[0014] In a further embodiment, a plurality of second circular holes are uniformly provided at the bottom of the first rectangular plate. The axis of the second circular holes is vertically arranged, and a terminal is fixedly installed in each of the second circular holes. The axis of the terminal is collinear with the axis of the second circular hole.

[0015] By adopting the above technical solution, the terminal can be accurately and stably positioned in the second circular hole, without any installation tilt or positional deviation caused by axis deviation. This facilitates smooth docking of the terminal with external connectors or other components. When a terminal malfunctions and needs repair or replacement, the collinear axis design allows maintenance personnel to accurately locate the terminal's position and installation direction, quickly complete the disassembly operation, and easily achieve precise positioning when installing a new terminal. This reduces the operational difficulty and time cost during maintenance, improves the efficiency of maintenance work, and reduces the impact of equipment downtime for maintenance on production or use.

[0016] In a further embodiment, the bottom of the base is provided with first annular protrusions symmetrically at the left and right ends, and the axis of the first annular protrusions is collinear with the axis of the corresponding first through hole.

[0017] By adopting the above technical solution, the fit between the first annular protrusion and the first through hole has a guiding function, and collinearity of the axes is a prerequisite for ensuring good guiding performance. It ensures that the moving parts move smoothly along a predetermined straight trajectory, avoiding jamming, deviation, or stuckness, thereby ensuring the smooth operation of the relevant mechanisms.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The protrusion of the first rectangular ring can protect the terminals and block dust.

[0020] 2. The use of solid nuts for riveting enables quick connection and increases structural strength;

[0021] 3. The design of the second rectangular plate and rectangular hole enables the heat generated inside the terminal to be conducted to the outside through the gap. Attached Figure Description
