Description

The connector of flexible circuit board

Technical field

The utility model relates to a kind of Soft Circuit Board Union, especially refer to make the lid displacement that on insulating base frame, reciprocatingly slides by Sliding Structures, and lid is closely pressed on the flexible circuit board, make itself and conducting terminal form the scraping of sliding, and then reach the excellent electrical property contact.

Background technology

Computer and electronics technology fast development now, and palmtop computer, notepad or notebook computer have been prevalent in each corner in the society all, its computer, it is also strong towards calculation function that gesture is driven in the development of electronic product, speed reaches the little direction of volume soon and strides forward, its inner connector volume also must significantly dwindle thereupon, light to adapt to present product, thin, short, gesture is driven in little development, right present employed Soft Circuit Board Union, see also Fig. 8,9, shown in 10, for TW announces " flexible base portion electrical cnnector " novel patent case the 23338 No. two, it is characterized by, the contact shoe A2 that has the majority of arranging elastic contact part at this peristome A1 of the shell A of opening upward, has the B1 of support sector of rotation at shell A or maintaining part B in the position that the member of this shell A faces above-mentioned peristome A1, the pressing element C of lid shape is rotating near the release position A21 of above-mentioned contact shoe A2 with from supporting freely according to the above-mentioned rotation B1 of support sector between the release position A21 that this allocation leaves, this pressing element C has the flexible base portion D that will be configured on the above-mentioned contact shoe A2 pressurization teat C1 to contact shoe A2 pressurization when above-mentioned institute allocation, this pressing element C when the release position than the line of the contact site A22 of center of rotation of link rotating the B1 of support sector and contact shoe A2 more to foreign side, when pressing element C turns to institute's allocation, will locate above above-mentioned line.

Above-mentioned existing flexible base portion electrical cnnector, still there are many defectives in its constructional device, for example:

(1) the contact shoe A2 of shell A inside, configuration is special to be had contact site A22 and rotates the A23 of support sector, so that the volume of shell A is big, can take bigger locus on circuit board.

(2) the pressing element C on the shell A, utilize pressurization teat C1 to support flexible base portion D and be positioned shell A, but pressing element C is not subjected to any location, touches, clashes into if be subjected to external force, even pressing element C breaks away from shell A, and causes flexible base portion D to separate with contact shoe A2.

(3) flexible base portion D is in the open space A21 of contact shoe A2, be subjected to the pressurization teat C1 of pressing element C extruding, hold, pass, and make flexible base portion D bear bigger torsional deformation, shorten the useful life of flexible base portion D easily, and flexible base portion D is detached shell A easily, causes electrically contacting the situation instability.

(4) the pressurization teat C1 of pressing element C has recessed axial region C11, articulate with the A23 of rotation support sector with shell A, so will take the inner space of shell A, cause the thickness of pressing element C to increase, and the thickness of shell A also increases, the material of making also increases, and improves manufacturing expense, is not inconsistent economic benefit.

So above-mentioned existing Soft Circuit Board Union is many defectives that produces when using, and then will how to solve its shortcomings and deficiencies, be the design people and the target and the direction place of being engaged in this journey improvement that the dealer desires most ardently.
