ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pair of connectors clamping a printed circuit board, particularly to a pair of connectors located back to back at opposite sides of the printed circuit board.
2. The Prior Art
Electrical connectors are used popularly for interconnection between two electrical devices which may be mother boards, hard disk drivers or the like. The interconnection configurations of the connectors and the electrical devices may be different according to respective structural requirements of electrical systems. One of the configurations is to provide a single connector having opposite mating surfaces for connection with electrical devices on opposite sides of a printed circuit board which has a hole for location of the opposite-mating-surface connector. However, the manufacturing of this kind of connector is difficult and high cost. Therefore, some manufacturers just make this connector separated into two connectors. For compensating the soldering strength of the pins in opposite sides of the printed circuit board, each connector is installed with a pair of board locks in distal ends thereof preventing the soldering circuit from being damaged during frequent insertion/withdrawal of the external electrical devices. However, this will make complicated on the printed circuit board because there are altogether four holes are needed for securing the board locks. U.S. Pat. Nos. 5,080,611, 5,254,016 and 5,921,812 disclose arrangements of two connectors mounted on two opposite sides of a single circuit board. Nevertheless, it is requisite to provide a new structure on the two connectors which need less board locks yet still maintain the securing function thereof.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide a pair of connectors fixed on opposite sides of a printed circuit board while using a common board lock secured to each other thereby clamping the printed circuit board.
One aspect of the present invention is to provide a pair of first connector and second connector clamping a printed circuit board therebetween. The first connector comprises a first body portion having a reception space defined from a bottom to a top thereof. The printed circuit board defines a hole registering with the reception space. The second connector comprises a second body portion defining a recess for receiving a board lock which has a fixed section engaged within the recess and a pair of spring prongs connected to the fixed section and retained in the reception space of the first connector, therefore the first connector and the second clamp the printed circuit board.
Another aspect of the present invention is to provide a connector assembly having a printed circuit board having a hole defined therein, a first connector having a first recess, and a second connector having a board lock extending therefrom for engagement with the first connector in the first recess thereof. The board lock of the second connector passes through the hole of the printed circuit board and the first connector and the second connector together clamp the printed circuit board.
Further another aspect of the present invention is to provide back-to-back connector assembly comprising a first connector and a second connector back-to-back installed on two opposite sides of a printed circuit board. The first connector comprises a first housing having a first mating face for engagement with an external electrical device and a first body portion in which a reception space is defined. The second connector comprises a second housing having a second mating face for engagement with another external electrical device and a second body portion from which a board lock extends. A printed circuit board has a hole through which the board lock of the second connector extends and engages within the reception space of the first connector. The first mating face of the first connector and the second mating face of the second connector are oriented in opposite directions.
