BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector structure, and more particularly, to an electrical connector structure having a heat dissipating component and a restraining component with simple structure, easy assembly, and an enhanced holding effect.
2. Description of the Prior Art
With rapid development of electronic industries and communication equipment, there are more and more standards for electrical connectors released. The current trend is towards to high frequency transmission and lightweight design. However, in order to satisfy requirements of the high frequency transmission and the lightweight design, contacts and wires per unit area inside the electrical connector become more and more concentrated, which increases the generated heat sharply and raises an operational temperature inside of the electrical connector when the electrical connector is in operation. It affects operational function of the electrical connector when the operational temperature is over a normal range of a design temperature, which impacts on performance of the electrical connector.
To ensure the electrical connector to be operated within the normal range of the design temperature, a heat dissipating device is usually adapted to the electrical connector for increasing heat dissipating efficiency. For example, a heat sink with thermal fins is one of the most common heat dissipating devices. A base of the heat sink is fixed on a housing of the electrical connector and attached on a surface of a plug module inserting into the electrical connector, so that the generated heat can be transferred to the base and thermal fins of the heat sink quickly when the electrical connector is in operation, which improves the heat dissipating efficiency.
A conventional heat sink is usually fixed on two sides of the housing of the electrical connector by clamping members or fixing members. However, movement of the conventional heat sink relative to the housing cannot be restrained due to manufacturing tolerances of components of the electrical connector and the conventional heat sink, so that the base of the conventional heat sink cannot be closely attached on the plug module adapted for the electrical connector all the times, which reduces thermal conductivity between the heat sink and the plug module and reduces the heat dissipating efficiency.

The first restraining segment 310 can be a flat plate extending along the lateral direction 190. The at least one extending element 340 includes a connecting portion 341 and a stopping portion 342. The at least one extending element 340 extends from at least one lateral side of the first restraining segment 310 and toward a rear side of the housing 100.

It depends on practical demands.
Please refer to FIG. 8 and FIG. 9. FIG. 8 is a lateral view of the electrical connector structure 10 according to the embodiment of the present invention. FIG. 9 is an enlarged sectional diagram of an A portion of the electrical connector structure 10 shown in FIG. 8 according to the embodiment of the present invention. Operational principle of the electrical connector structure 10 of the present invention is introduced as follows. For coupling the heat dissipating component 200 and the housing 100 by the restraining component 300, the restraining component 300 is to be assembled from the rear side of the housing 100. The two extending elements 340 located at two lateral sides of the first restraining segment 310 are connected to the two restraining slots 141, 142, respectively. At this time, the first restraining segment 310 contacts with the top wall 111. Parts of the two connecting portions 341 contact with the top wall 111. The two stopping portions 342 contact against an inner surface of the rear wall 113. The two restraining segments 320 drive the two pressing portions 321 to contact with the heat dissipating component 200. Therefore, movements of the heat dissipating component 200 along the vertical direction 191 and the longitudinal direction 192 are restrained accordingly.
Furthermore, the two first restraining arms 161 and the two pressing portions 321 contact with the heat dissipating component 200 cooperatively for providing the enhanced holding effect downwardly to fix the heat dissipating component 200 at the position corresponding to the top opening 150, so that the engagement surface 210 can be closely attached on the plug module, which improves the holding effect.
Besides, when the heat dissipating component 200 is fixed on the housing 100 by the restraining component 300, the second restraining arm 162 is located between the heat dissipating component 200 and the housing 100 for providing a buffering effect upwardly against the downward holding effect provided by the two pressing portions 321, which prevents a front end of the heat dissipating component 200 from being pried relative to the housing 100 by the two pressing portions 321. Therefore, it solves a problem of poor heat dissipating efficiency caused by incomplete attachment of the heat dissipating component and the plug module.
Moreover, when the heat dissipating component 200 is fixed on the housing 100 by the restraining component 300, the two first restraining arms 161, the second restraining arm 162 and the two pressing portions 321 are coupled to the heat dissipating component 200 for cooperatively fixing the heat dissipating component 200 at the position corresponding to the top opening 150, so as to restrain the movements of the heat dissipating component 200 along the vertical direction 191 and the longitudinal direction 192, so that the engagement surface 210 can be attached on the plug module closely at all times, which enhances thermal conductivity between the plug module and the heat dissipating component 200 and improves the heat dissipating efficiency.
In contrast to the prior art, the electrical connector structure of the present invention utilizes the restraining component mechanically coupled between the heat dissipating component and the housing for solving a problem of the poor heat dissipating efficiency caused by incomplete attachment of a conventional heat sink and a plug module. Furthermore, the restraining component of the electrical connector structure of the present invention has advantages of simple structure and easy assembly. Besides, a position of the heat dissipating component 200 relative to the top opening 150 is fixed at all times and is not affected by insertion and pulling out of the plug module, which improves a positioning effect and the holding effect.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
