Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

The first embodiment of the printed board assembly comprises a printed board and a board-to-board connector fixedly mounted on the printed board. The structure of the board-to-board connector is shown in fig. 1-2, and comprises an insulating block 1, wherein the insulating block 1 is approximately rectangular, a plurality of vertical spacers 11 are arranged on the upper side surface of the insulating block 1 at intervals along the length direction, an installation groove is formed between the two vertical spacers 11, and two contact pieces are symmetrically arranged in the installation groove in the width direction.

Taking a contact element in the width direction as an example, the contact element comprises a horizontal supporting section 21 extending along the bottom of the mounting groove, one end of the horizontal supporting section 21 extending out of the lateral notch of the mounting groove is provided with a vertical transition section 20 vertically extending along the outer side surface of the insulating block 1, the lower end of the vertical transition section 20 is provided with a pin 24, and the contact element is connected with the printed board in a welding mode through the pin 24. The other end of horizontal support section 21 has the elasticity overhanging section 22 that the inflection upwards extended and stretched out from the upside notch of mounting groove, and the tip that elasticity overhanging section 22 exposes notch on the mounting groove still is connected with inflection downwardly extending's elastic support section 23, and wherein, elastic support section 23 is roughly parallel with elasticity overhanging section 22. The contact part 29 is formed at the topmost part of the folding connection part of the elastic overhanging section 22 and the elastic supporting section 23, and when the other printed board is pressed downwards along the direction vertical to the board surface, the contact part on the other printed board can be elastically abutted with the contact part 29, so that the conductive connection between the two parallel printed boards is realized. In addition, when another printed board is pressed downwards along the direction perpendicular to the board surface, the elastic overhanging section 22 is elastically deformed and pressed downwards, the lower end of the elastic supporting section 23 can abut against the horizontal supporting section 21 and provides elastic supporting force for the elastic overhanging section 22, and the reliability of contact between the contact element and the upper printed board is ensured.

Of course, when the elastic overhanging section 22 and the elastic supporting section 23 are deformed under pressure, lateral sliding may occur at the abutting portions of the elastic supporting section 23 and the horizontal supporting section 21, and for facilitating the lateral sliding, the lower end of the elastic supporting section 23 is provided with a curved portion to abut against the horizontal supporting section 21 through the outer curved surface of the curved portion.

A stop block 12 for laterally stopping the contact element is further arranged in the mounting groove at the folding position of the horizontal supporting section 21 and the elastic overhanging section 22. The stopper 12 can support the contact member in cooperation with the bottom of the mounting groove when the elastic overhanging section 22 is pressed by the upper printed board. Preferably, the stopper 12 is spaced apart from the bottom of the mounting groove to form a channel therebetween, which facilitates the airflow passing through the mounting groove and facilitates the heat dissipation of the contact.

The contact member passes through horizontal support section 21 and mounting groove fixed connection, specifically, can adopt sticky, or set up the card that extends towards the opposite side cell wall respectively on the both sides cell wall of mounting groove, the contact member passes through the card chucking on the tank bottom surface of mounting groove. Because the contact area of the horizontal supporting section 21 and the mounting groove is large, reliable fixed connection is convenient to realize.

In addition, in order to guarantee that the elastic overhanging section 22 is located in the elastic deformation limit range and prolong the service life of the connector, the upper groove edge of the mounting groove, namely the upper end face of the vertical spacer can limit the printed board on the upper side when the contact element is pressed down on the printed board on the upper side.

Of course, the printed board assembly of the present invention is not limited to the above-described embodiments, and particularly, the board-to-board connector included in the printed board assembly is not limited to the board-to-board connector in the above-described embodiments.

Fig. 3-4 show a connector that differs from the board-to-board connector of the above-described embodiment. The board-to-board connector in this embodiment is different from the board-to-board connector in the above embodiments in that only one contact element is installed in each installation groove, and the upper end of the elastic overhanging section 22 of the contact element is not connected with an elastic supporting section for elastically supporting the contact element, but is provided with a bending section 26, and the bending section 26 and an upper convex outer arc surface formed by bending the elastic overhanging section 22 form a contact portion 29 for abutting against an upper printed board.

The horizontal supporting section 21 is provided with a clamping part 28 which protrudes and extends in the width direction of the sheet body, the bottoms of the two side groove walls of the mounting groove are respectively provided with a slot, when the contact element is mounted in the mounting groove, the contact element is inserted into the mounting groove from a left side notch (as shown in the figure), and the clamping part 28 is correspondingly inserted into the slots at the bottoms of the two side groove walls, so that the fixation of the contact element in the mounting groove is realized.

In other embodiments, the extending direction of the elastic supporting section may be opposite to the extending direction of the elastic overhanging section, that is, the two and the horizontal supporting section form a triangular structure; the contact piece can also be fixedly connected with the insulating block through the vertical transition section; or, set up spacing lug at the upside of vertical spacer, it is spacing with upside printed board butt through the top of spacing lug.

When the printed board assembly is used, only the other parallel printed board hole is required to be close to the printed board in the direction vertical to the board surface, and the contact on the printed board hole can be elastically abutted with the contact element of the board-to-board connector, so that the printed board assembly and the printed board connector are in conductive connection, two connectors connected with the two printed boards do not need to be respectively plugged, and the connecting space is greatly saved. In the board-to-board connector in the printed board assembly, most of the contact elements are exposed outside the insulating block, and dead angles wrapped by the insulating block are avoided, so that the printed board assembly is good in heat dissipation effect and very suitable for occasions with high density.

An embodiment of the board-to-board connector of the present invention: the specific structure is the same as the board-to-board connector structure in the above-mentioned various embodiments of the printed board assembly, and the detailed description is omitted here.
