Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a 16P connector structure. Background Technology

[0002] Pin headers are devices consisting of insulated metal pins arranged at specific intervals with various plastic frames, used for signal and power transmission between boards or different modules. These connectors are widely used in PCBs (Printed Circuit Boards) in electronics, electrical appliances, and instrumentation. Their function is to act as a bridge between blocked or isolated circuits, facilitating current or signal transmission. They are typically used with female headers to form board-to-board connections; or with electronic wire harness terminals to form board-to-wire connections; or they can be used independently for board-to-board connections.

[0003] Pin headers are a type of connector terminal used to achieve electrical connections. As electrical connection accessories, connector terminals generate heat during prolonged use. If the heat is not dissipated in time, it can easily cause electrical circuit breakage or even electrical fire. To address this, some connector assemblies have heat dissipation structures, but these structures usually consist of a heat-dissipating coating on the outer surface of the plastic base. This method of heat dissipation through a single heat-dissipating coating is ineffective, as the heat cannot be dissipated in time.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a 16P connector structure. By recessing a first heat dissipation groove and a second heat dissipation groove on the upper and lower surfaces of the plastic base, the upper and lower surfaces of the plastic base are hollowed out, increasing the contact area between the plastic base and the air, making it easier for heat to be transferred from the inside to the surface of the hollow groove. Secondly, the heat dissipation holes that run through the upper and lower surfaces provide a channel for airflow, thereby carrying away the heat generated by the terminal block and connector during operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A 16P connector structure includes a plastic base and a terminal group; the terminal group is inserted and fixed in a terminal hole, the terminal group has a plurality of terminals, and each terminal includes an integrally formed contact portion, a connecting portion and a soldering portion; the terminals extend into the plastic base, and the contact portion and the soldering portion are respectively exposed outside the plastic base;

[0008] The plastic base has an upper end face, a lower end face, a front end face, and a rear end face; the upper end face is provided with a plurality of first heat dissipation grooves and a plurality of first heat dissipation through holes at intervals, the first heat dissipation through holes passing through the plastic base vertically and located beside the terminal; the lower end face is provided with a plurality of second heat dissipation grooves at intervals, wherein the plurality of second heat dissipation grooves are arranged vertically opposite to the plurality of first heat dissipation grooves; the rear end face is provided with a second heat dissipation through hole, the second heat dissipation through hole being connected to the first heat dissipation through hole.

[0009] As a preferred embodiment, the plurality of first heat dissipation grooves are recessed downward from the upper end surface of the plastic base; the plurality of second heat dissipation grooves are recessed upward from the lower end surface of the plastic base, wherein there is a gap between the first heat dissipation grooves and the second heat dissipation grooves.

[0010] As a preferred embodiment, dustproof nets are provided at the openings of the plurality of first heat dissipation slots and the plurality of second heat dissipation slots.

[0011] As a preferred embodiment, the connecting part is provided with a limiting protrusion to prevent the terminal from becoming loose when it is inserted into the plastic base. Correspondingly, the plastic base is provided with a groove that matches the limiting protrusion. When the terminal is inserted into the plastic base, the limiting protrusion is located in the groove.

[0012] As a preferred embodiment, the upper and lower ends of the limiting protrusion are respectively provided with a first guide slope and a second guide slope for guiding the insertion of the terminal.

[0013] As a preferred embodiment, the first heat dissipation through hole extends downward from the upper end face of the plastic base and the second heat dissipation hole extends forward from the rear end face of the plastic base, such that the second heat dissipation hole is connected to at least a portion of the first heat dissipation hole.

[0014] As a preferred embodiment, the diameter of the first heat sink is larger than the diameter of the second heat sink arm.

[0015] As a preferred embodiment, the rear end face of the plastic base is provided with a positioning part for subsequent plug-in connection and positioning with external products, and the positioning part extends beyond the lower end of each welding part.

[0016] As a preferred embodiment, the positioning part is further recessed with a docking groove, which is used to cooperate with the docking part of an external product.

[0017] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves recessing a first heat dissipation groove and a second heat dissipation groove on the upper and lower surfaces of the plastic base, respectively. In this way, the upper and lower surfaces of the plastic base are hollowed out, increasing the contact area between the plastic base and the air. This makes the plastic of the terminal connection part thinner, and the heat is more easily conducted to the upper surface of the plastic, reducing the thermal resistance and making it easier for heat to be transferred from the inside to the surface of the hollow groove.

[0018] Secondly, the through-hole ventilation holes provide a channel for airflow. When there is a temperature difference, hot air will rise and cold air will come in, forming natural convection and continuous circulation, thereby carrying away the heat generated by the terminal block and connector during operation.

[0019] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description
