Problems solved by technology

[0008] When circuit board connectors are used to connect power modules or components, especially for interconnections involving relatively large currents, a problem arises: the dissipation of heat generated by the current in the connector
In the existing connectors described above, there is no special modification to improve the heat dissipation of the connector

Embodiment Construction

[0039] With reference to the drawings, it should be understood that the present invention can be implemented in different shapes and ways. The description of the specific embodiments disclosed in the present invention given below is only exemplary.

[0040] Figure 1 shows a jumper mounting board edge connector for mounting on the edge portion of a printed circuit board. The connector includes an insulating housing 1 in which separate conductive terminals 2, 3 are installed. In a typical application, the connector is used as a jumper mounting board edge connector to mount or connect a voltage regulation module (VRM) to the peripheral edge of a printed circuit board (PCB), which will be described in more detail below.

[0041] The terminals 2, 3 are flat, parallel to each other, spaced apart from each other, and aligned in a row in the connector housing 1 together. These terminals are preferably made of metal by stamping and forming from sheet metal or metal tape. The shapes of the ...

Abstract

An electrically conductive terminal 2, 3 for a circuit board connector has a heat sink fin 16 which is thermally coupled to two connection portions 12, 14 for dissipation of heat generated in the connection portions. The heat sink fin and one of the connection portions 12 extend from a central body portion 10 in the same direction. The heat sink fin is preferably located outside one of the connection portions 12 to protect the latter from physical damage. A lock portion 18 , with a barb 26 for retaining the terminal in the connector housing 1 , may extend from the central body portion in a direction opposite to the heat sink fin 16 . The terminal 2, 3 , and particularly the lock portion 18 , can be inserted into a cavity 28 in the connector housing 1 by pushing on the distal end 24 of the heat sink fin. The terminal may be stamped from a sheet metal material. Also claimed is a connector having a row of such terminals mounted with a common alignment and with the heat sink fins located outside the connector housing.

Description

Technical field [0001] The present invention relates to electrical connectors, in particular to electrical connectors for printed circuit boards, as well as printed circuit board edge connectors that can be applied to high current applications, such as voltage regulators or other power modules. Background technique [0002] The invention can be applied to a module, that is, an electrical interconnection between an assembly of electronic components and a printed circuit board. It is known to use a dedicated connector in which one or more rows of terminals are mounted on a slender housing. Each terminal has a connection tail and a socket part, the connection tail being used to connect to a corresponding conductive rail on the circuit board, for example, by soldering, and the socket part is used to releasably connect to the module. The module can be a circuit board that is supported by a connector and connected to another printed circuit board. In this case, the module and the other...
