Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to an electronic connector for heat dissipation. Background Technology

[0002] An electrical connector is an electronic component that enables circuit connection and disconnection through a mechanical structure. Its core function is to establish a reliable electrical signal transmission channel between devices, components, or systems, while allowing physical separation and repeated plugging and unplugging operations. Some electrical connectors, after being soldered to telecommunications connection equipment, suffer from limitations in the overall structure and space of the telecommunications equipment, making the external plug and connector mating inaccurate and inconvenient. Furthermore, after mating, the connector is prone to shifting or displacement under external force, affecting signal transmission. In addition, the heat generated by the connector during signal transmission cannot be dissipated quickly, resulting in low heat dissipation efficiency. This utility model aims to solve the above problems. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an electronic connector.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: It includes an insulating base and a terminal module assembled and connected to the insulating base. The insulating base includes a front end face, a rear end face parallel to the front end face, and a bottom side face perpendicular to both the front and rear end faces. The front end face has a mating hole, and the rear end face has an assembly hole. The terminal module is assembled into the insulating base through the assembly hole and extends into the mating hole. The terminal module contains a bent terminal, which extends towards and out of the bottom side face. The front end face has a positioning hole one and a positioning hole two communicating with the mating hole. Two positioning holes one are provided and arranged side-by-side on the upper side of the mating hole. The cross-sectional shape of each positioning hole one is T-shaped and the depth is the same as that of the mating hole. The positioning hole two is located on the lower side of the mating hole, and the depth of the positioning hole two is less than the depth of the mating hole.

[0005] Preferably, the cross-sectional shape of the second positioning hole is quadrilateral, and the upper side of the second positioning hole is connected to the mating hole. The entrances of the mating hole, the first positioning hole, and the second positioning hole are all provided with guide angles.

[0006] Preferably, the bottom side surface is provided with a clearance groove extending toward the front end surface, the assembly hole communicates with the clearance groove, and the end of the clearance groove facing the outside is provided with a ventilation opening.

[0007] Preferably, the width of the second positioning hole is set to be greater than 1 / 4 of the width of the mating hole and less than 1 / 3 of the width of the mating hole.

[0008] Preferably, the mating hole has a mating bottom side surface, and the distance between the bottom side surface and the mating bottom side surface of the mating hole is set to 3.45+0.20 / -0.20MM.

[0009] The beneficial effects of this utility model are that it provides an electronic connector. When applied, an external plug is inserted into the connector through a mating hole. Positioning holes one and two constrain the external plug from different angles. The depth of positioning hole two is less than the depth of the mating hole, while the depth of positioning holes one is the same as the mating hole. The cross-sectional shape of positioning holes one is T-shaped, thus creating a stop at different depths between the external plug and the connector, ensuring no displacement or offset during insertion and guaranteeing stable signal transmission. The width of positioning hole two does not affect the strength of the mating hole and also facilitates insertion of the external plug into the connector. The clearance groove and ventilation notch form a heat dissipation channel connecting the bent terminal to the outside, improving heat dissipation efficiency. The increased distance between the bottom and bottom sides of the mating hole increases the distance between the mating opening and the bottom side, facilitating insertion of the external plug into the mating hole.

[0015] Reference Figures 1 to 3 This utility model is implemented as follows: An electronic connector includes an insulating base 1 and a terminal module 2 assembled and connected to the insulating base 1. The insulating base 1 includes a front end face 11, a rear end face 12 parallel to the front end face 11, and a bottom side face 13 perpendicular to both the front end face 11 and the rear end face 12. The front end face 11 is provided with a mating hole 14, and the rear end face 12 is provided with a mounting hole 15. The terminal module 2 is assembled into the insulating base 1 through the mounting hole 15 and extends into the mating hole 14. The terminal module 2 has a fold inside. The bent terminal 21 extends toward the bottom side surface 13 and extends beyond the bottom side surface 13. The front end surface 11 is provided with a positioning hole 111 and a positioning hole 112 communicating with the insertion hole 14. Two positioning holes 111 are provided and are arranged side by side on the upper side of the insertion hole 14. The cross-sectional shape of the positioning holes 111 is T-shaped and the depth is the same as that of the insertion hole 14. The positioning hole 112 is located on the lower side of the insertion hole 14 and the depth of the positioning hole 112 is less than the depth of the insertion hole 14.

[0016] In application of this utility model, the external plug is inserted into the utility model through the mating hole 14. When the external plug enters the mating hole 14, it simultaneously enters positioning hole one 111 and positioning hole two 112, ensuring a more precise and stable mating between the external plug and the utility model. Positioning hole one 111 and positioning hole two constrain the external plug from different directions. The depth of positioning hole two 112 is less than the depth of mating hole 14. Positioning hole one 111 has the same depth as mating hole 14. The cross-sectional shape of positioning hole one 111 is T-shaped, thereby forming a stop at different depths between the external plug and the utility model, ensuring that the external plug and the utility model will not be displaced or offset during mating, and ensuring stable signal transmission.

[0017] Based on the above embodiments, as a further preferred embodiment, the cross-sectional shape of the second positioning hole 112 is set to quadrilateral, and the upper side of the second positioning hole 112 communicates with the mating hole 14, thereby constraining the external plug from different directions to ensure stable signal transmission. The entrances of the mating hole 14, the first positioning hole 111, and the second positioning hole 112 are all provided with guide angles 115 to facilitate the smooth mating of the external plug with the present invention. The width of the second positioning hole 112 is set to be greater than 1 / 4 and less than 1 / 3 of the width of the mating hole 14. The width setting of the second positioning hole 112 does not affect the strength of the mating hole 14, and at the same time facilitates the mating of the external plug with the mating hole 14 of the present invention.

[0018] Based on the above embodiments, as a further preferred embodiment, the bottom side surface 13 is provided with a clearance groove 131 extending towards the front end surface 11, the mounting hole 15 communicates with the clearance groove 131, and the end of the clearance groove 131 facing the outside is provided with a ventilation opening 132. The clearance groove 131 and the ventilation opening 132 allow the bent terminal 21 to communicate with the outside after welding, forming a heat dissipation channel between the bent terminal 21 and the outside, thus improving heat dissipation efficiency.

[0019] Based on the above embodiments, as a further preferred embodiment, the mating hole 14 is provided with a mating bottom side, and the distance between the bottom side side 13 and the mating bottom side side 13 of the mating hole 14 is set to 3.45 + 0.20 / - 0.20 mm. Without significantly increasing the overall external dimensions of this utility model, increasing the distance between the mating bottom side and the bottom side side 13 of the mating hole 14 increases the distance between the mating hole and the bottom side side 13, facilitating the mating of external connectors with the mating hole 14.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
