Description

Electric connector

Technical Field

The invention relates to a connecting terminal device for realizing plug-in type electric connection between electrical equipment, in particular to an electric connector with an efficient heat dissipation structure.

Background

Transceivers are commonly used to connect network equipment (e.g., switches, wiring boxes, computer input/output ports, etc.) to optical fibers or UTP cables. In order to increase port density, transceiver miniaturization is often desirable. A Small Form Pluggable (SFP) transceiver is a transceiver with a Small size and low power consumption, which is used for optical communication applications in telecommunication or data communication. In addition, another transceiver that uses the SFP + standard shifts the signal modulation functions, serializer/deserializer, clock and data recovery, and electronic dispersion compensation functions from the transceiver to the circuit board and is therefore smaller in size.

The existing hot plug connector generally comprises a shell, an insulating body accommodated in the shell, a clamping piece installed on the insulating body and a supporting piece supporting the clamping piece. The structures are combined tightly, so that high heat dissipation requirements are met in the long-term operation process, and when the types of equipment are more multiple, namely when the equipment is combined by a plurality of plug-in clamping structures, the heat dissipation requirements are more prominent, and higher requirements are inevitably provided for the heat dissipation performance of the equipment.

Detailed Description

The present invention will be further explained with reference to the following embodiments, which are intended to illustrate the present invention only and not to limit the scope of the present invention, and directional terms such as front, back, left, right, up, down, etc. in the following description are only used for the convenience of the reader's understanding in conjunction with the accompanying drawings.

As shown in fig. 1 and 2, the electrical connector disclosed in the present invention includes a housing and a heat dissipation structure formed outside the housing, and the rest is the prior art in the field to form a complete technical solution of the present invention, and the heat dissipation structure is mainly used for implementing the heat dissipation function of the present invention, and the heat dissipation structure includes a heat dissipation plate i and a heat dissipation plate ii, so that the heat dissipation plate combination structure provides a larger heat dissipation area on one hand, thereby facilitating heat dissipation; on the other hand, a space channel is formed between two adjacent radiating fins, so that the circulating flow of cold/hot air is facilitated, and a better radiating effect is obtained;

at the moment, the radiating fins I are positioned in the array I, the array I is formed by arranging a plurality of radiating fins I in parallel, and the structure of the array I and the arrangement number of the radiating fins I are designed according to the specific size of a connector product and the size of the radiating fins I and by matching with radiating requirements and the like;

the radiating fins II are positioned in the array II, and the array II is formed by parallelly arranging a plurality of radiating fins II; the radiating fins I have heights I, the radiating fins II have heights II, and the structure of the array II and the arrangement number of the radiating fins II are designed according to the specific size of the connector product and the size of the radiating fins II and the radiating requirements and the like.

In the above solution, the heat sink i and the heat sink ii have respective thicknesses d1 and d2, which may be the same or different. As a further improvement, d1 is here equal to or greater than d 2. The heat dissipation performance of the product is improved by adjusting the heat dissipation surface areas of different areas by adopting the heat dissipation fins with different thicknesses, and the improvement can further play a role in adjusting the surface thermodynamic air circulation when being matched with gaps among the heat dissipation fins so as to further enhance the corresponding heat dissipation effect.

In the above solution, the fin i and the fin ii have respective heights h1 and h2, which may be the same or different. As a further improvement, h1 is greater than or equal to h 2. The different arrays adopt the radiating fins with different heights, and air masses with different temperatures in different height areas can be formed on the surface of the radiating structure, so that the formation of thermodynamic circulating airflow on the surface of the radiating structure is promoted, and the radiating effect is enhanced.

In the above-mentioned scheme, as a specific embodiment shown in fig. 1 and fig. 2, in the scheme, a plurality of radiating fins i in an array i are arranged in parallel, and gaps i are formed among the radiating fins i. The radiating fins II in the array II are arranged in parallel, and gaps II are formed among the radiating fins II. The gaps increase the heat dissipation surface area provided by the heat dissipation array on one hand, and the gaps formed between the gaps further form thermodynamic circulating air flow, so that the thermodynamic flow of air on the surface of the array is enhanced, and the connector has no doubt more efficient heat dissipation means and heat dissipation efficiency.

More preferably, in the array I, a gap I is formed between two adjacent radiating fins I, and the gap I has a width w 1. In addition, in the array II, a gap II is formed between two adjacent radiating fins II, and the gap II has a width w 2. And w1 is not less than d 2; w2 is d1 or higher. The matching of the gap and the radiating fins in the aspects of thickness and width effectively improves the flow of thermodynamic air flow on the surface of the radiating structure, particularly the radiating fins, and promotes the exchange of circulating air flow so as to enhance the radiating effect.

Furthermore, w1 is greater than or equal to w2, and heat dissipation is effectively achieved by adopting gaps with different widths in different arrays and matching with heat dissipation fins with different widths and heights to directly form heat dissipation airflow in array gaps, heat dissipation fin gaps and the like.

In the above embodiment, on the premise that the arrangement direction of the heat dissipation fins i in the array i is the same as that of the heat dissipation fins ii in the array ii, the heat dissipation fins i in the array i may be opposite to the heat dissipation fins ii in the array ii, or may be opposite to the gaps ii in the array ii; similarly, the heat sink fins II in array II can also be opposite to the gaps I in array I.

The fixing structure 6 comprises a fixing part and a pressing part, wherein the pressing part is connected to the fixing part, the pressing part connecting plate has a locking function, the fixing structure 6 is locked on the shell of the connector through the fixing part, and the pressing part further locks and limits the connecting plate so as to be tightly attached to the shell. For example, as shown in fig. 1 and 2, the fixed part is in the vertical direction, while the pressing part is mainly in the horizontal direction or the nearly horizontal direction, and the two parts are integrally in a fold line type or a nearly fold line type. The fixing part may have a plate-shaped structure, and the fixing hole may be provided thereon, and the housing corresponding to the fixing hole connector may further be provided with a connecting hole, so as to lock or protrude the connecting hole and the fixing hole by using a technique such as a screw, a rivet, or welding, and the engaging member may be a protrusion, and may be engaged with the fixing hole to lock the fixing part to the housing, such as a side edge in the figure.
