Description

Soft Circuit Board Union

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of Soft Circuit Board Union especially.

[background technology]

Seeing also Fig. 1 and Fig. 2, is to be a kind of known Soft Circuit Board Union, and it includes terminal 15, a packing assembly 20 of a pedestal 10, majority; Wherein this pedestal 10 is to be separated into most a terminal groove 12 and a link slot 13 by shim 11; This terminal 15 is to be provided with a pin portion 16, two side arms 17, an and elastic arm 18, and this pin portion 16 stretches out outside the pedestal 10, this two side arms 17 and terminal groove 12 packings, and this elastic arm 18 is provided with a contact 19 that is protruding to link slot 13; This chases after tight assembly 20 is that both sides are connected on the pedestal 10, and it is provided with a packing sheet 21 that protrudes, and this packing sheet 21 is the link slots 13 that can fill in this pedestal 10.

See also Fig. 3, known Soft Circuit Board Union is packing assembly 20 is pulled out and to face upward in use, flexible circuit board 25 0 intercalations are gone in the link slot 13, as shown in Figure 4, when again the packing sheet 21 of packing assembly 20 being filled in link slot 13, can be electrically connected with the contact 19 of terminal 15 by packing flexible circuit board 25.

Known design has following shortcoming:

1. come packing flexible circuit board 25 to be electrically connected by this packing assembly 20, so necessary clamping packing assembly 20 in the both sides of its pedestal 10, yet the Soft Circuit Board Union volume is just very little originally, more hour then pedestal 10 can be littler for few or spacing when number of terminals, so to design two very widgets (pedestal 10 and packing assembly 20) mutually clamping slide and make packing sheet 21 fill in the link slot 13 of this pedestal 10, very difficult, precision is very high, because the product of assembling has cumulative limit, assemble at two very little objects, very high precision need be arranged, otherwise cause assembly failure because of both cumulative limit.

2. owing to flexible circuit board 25 is that zero intercalation is gone in the link slot 13 of pedestal, there is not friction to strike off the effect of oxide layer of the contact 19 of terminal, and the contact 19 of terminal is because of being exposed in the air by coating, the stability of shadow when being electrically connected so then can produce oxide layer when a period of time does not use.

Conventional designs also has the design of a kind of cover-lifting type, and its packing assembly is to adopt the flip mode to reach packing or loosen flexible circuit board, makes up so it equally also is the pivot joint of two of pedestal and packing assemblies, so also have above-mentioned shortcoming.

[utility model content]

The purpose of this utility model is to provide a kind of Soft Circuit Board Union, flexible circuit board zero intercalation is gone into after packing location again, have and make simple and easyly, can reduce production costs, have the effect that the contact that prevents terminal produces oxide layer simultaneously.

In order to achieve the above object, the utility model provides a kind of Soft Circuit Board Union, it is characterized in that: include:

One pedestal is provided with most shims of equidistantly arranging in this pedestal, this majority shim defines most a terminal groove and a link slot in this pedestal, and this link slot is provided with an open end, and these pedestal both sides respectively are provided with a socket part;

Most terminals, this each terminal is to be located at respectively in the terminal groove of this pedestal, this terminal is provided with a pin portion, a location division, reaches one first elastic arm, this pin portion stretches out outside this pedestal, the terminal groove fit of this location division and this pedestal, this first elastic arm is provided with the contact of the link slot that is protruding to this pedestal, and this contact is electrically connected with the flexible circuit board that inserts this pedestal;

One fastening piece, this fastening piece are to be assembled in this pedestal and an end exposes outside this pedestal, this fastening piece and the combination of this pedestal, and terminal that should majority compresses and is positioned in this pedestal;

Two fixation kits are that the socket part that is sleeved on these pedestal both sides becomes to be slidingly matched, and this fixation kit is to be fixed on the circuit board.

Described Soft Circuit Board Union is characterized in that: this terminal is provided with second elastic arm, and this second elastic arm presses on this above link slot.

Described Soft Circuit Board Union is characterized in that: this terminal is provided with a stop section in the rear of this contact, and this stop section block is in the insertion end of this flexible circuit board.

Described Soft Circuit Board Union is characterized in that: the socket part of this pedestal is provided with a platform, and the central authorities of this platform are provided with one first projection, and the leading portion of this platform is provided with one second projection, and the back segment of this platform is provided with a concave surface; The cross section of this fixation kit is the Contraband shape, be provided with top board and base plate, the central authorities of this top board are provided with perforate and a back segment inner face long than this first projection and are provided with one the 3rd projection, the perforate that first projection of this socket part engages this top board becomes to be slidingly matched, this second projection is butted on the top board of this fixation kit, and the 3rd projection then is butted on the platform of this socket part.

Described Soft Circuit Board Union is characterized in that: first projection of the socket part of this pedestal is provided with the guide face of inclination laterally.
