Abstract
The utility model discloses an electric connector for plugging with a flexibility circuit board, comprising an insulated body, a conductive terminal contained in the insulated body, a gland which is movably assembled with the insulated body, and locking devices which are fixed on the two opposite terminals of the insulated body. The insulated body is provided with a plugging interface which is plugged with the flexibility circuit board, and the gland moves between an opened position and a closed position. The gland is provided with a brake mechanism which is matched with the locking devices for realizing that the gland moves between the opened position and the closed position. When the gland moves from the opened position to the closed position, the brake mechanism and the locking devices are matched to press the flexibility circuit board for achieving the electrical connection between the flexibility circuit board and the conductive terminal; additionally, the match between the brake mechanism and the locking devices generates self-lock, and thus the quitting process of the gland is easily realized while the flexibility circuit board is pressed.
Description
[technical field]
The utility model is about a kind of electric connector, especially a kind of electric connector of the flexible PCB that is used to peg graft.
[background technology]
The existing electric connector that is used to connect flexible PCB generally comprises insulating body, is contained in conducting terminal and the removable gland that is connected to insulating body in the insulating body.Gland can move between enable possition and make position, when gland is in the enable possition, flexible PCB can freely insert in the insulating body, and when gland was in the close position, gland compresses flexible PCB made the conducting terminal that is placed in the insulating body electrically contact with flexible PCB.
Yet when gland was in the close position, gland was subjected to very easily opening from the bounce of conducting terminal.In addition, along with modern electronic product towards trend light, thin, short and small development, reduce the electric connector height and also become an urgent demand, therefore, also corresponding requirements gland slimming.
In order to realize the low dwarfing of electric connector, if with the gland reduced thickness, then gland very easily produces deflection being under the closure state, and correspondingly, the pressure potential that gland compresses flexible PCB must weaken, and may cause the phenomenon of poor flow thus.
So, attempted when gland is in closure state, cooperate with sticking department on being located at insulating body by the auxiliary section that is located on the gland, preventing also can to prevent the gland deflection when gland from throwing.
As shown in Figure 1, the Taiwan patent announcement disclosed for No. 532583 a kind of electric connector 1 of the flexible PCB (not shown) that is used to peg graft ', it comprise insulating body 2 ', be housed in insulating body 2 ' interior in order to the conducting terminal 16 that electrically connects flexible PCB and printed circuit board (PCB) (not shown) ' and removable be connected to insulating body 2 ' gland 3 '.Wherein, insulating body 2 ' be provided with in order to accommodate conducting terminal 16 ' groove 14 ', the accepting groove 18 that inserts of ccontaining flexible PCB ' and be positioned at the buckle slot 13 at two ends '.Gland 3 ' be provided with in order to the tongue 32 that compresses flexible PCB ' and the brake mechanism 24 at two ends, position '.This brake mechanism 24 ' have button gripping arm 26 ' and be positioned at button gripping arm 26 ' on first, second button hold piece 243 ', 244 '.When gland 3 ' when being in closure state, gland 3 ' tongue 32 ' be contained in insulating body 2 ' accepting groove 18 ' in, simultaneously, gland 3 ' button gripping arm 26 ' the enter corresponding buckle slot 13 in insulating body 2 ' two ends ' in.Gland 3 ' button gripping arm 26 ' on first, second button hold piece 243 ', 344 ' with projection (not shown) buckle of insulating body 2 ' buckle slot 13 ' interior relative set, thereby with gland 3 ' be fastened in make position, so prevent gland 3 ' because of be subjected to from conducting terminal 16 ' bounce get loose.
Yet, though this kind mode of holding can more firmly be fastened in gland in the insulating body when gland is in closure state, but, make gland get back to the enable possition when braking gland, then very easily cause the destroyed even fracture of projection on the gland button gripping arm, and then shorten the useful life of gland.
Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of existing electric connector.
[utility model content]
The purpose of this utility model provides a kind of gland and can compress flexible PCB and realize the electric connector that gland withdraws from from make position easily in make position.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, in order to the grafting flexible PCB, it comprises insulating body, is housed in conducting terminal, the removable locked instrument that is connected to the gland of insulating body and is retained on the insulating body opposite end in the insulating body.Insulating body is provided with the interface of grafting flexible PCB; Gland can move between unlatching and make position.Gland is provided with brake mechanism, brake mechanism cooperates with locked instrument realizes that gland moves between unlatching and make position, when gland when the enable possition moves to make position, brake mechanism cooperates with locked instrument and compresses flexible PCB, make flexible PCB and conducting terminal reach electric connection, and utilize cooperating of brake mechanism and locked instrument to produce self-locking, thereby when compressing flexible PCB and can easily realize the process that withdraws from of gland.
Compared to prior art, the utility model electric connector is by when gland is in the close position, brake mechanism cooperates the generation self-locking and makes gland compress flexible PCB with locked instrument, make flexible PCB and conducting terminal reach electric connection, if gland will be withdrawed from from make position, only need that gland is applied one and enter the opposite power of the force direction of make position and destroy its self-locking and can conveniently withdraw from, thereby avoid damaging gland with pushing gland, and then the useful life of prolongation gland.
