Please continue to refer to shown in Fig. 3 to Fig. 6, the rack body 10 is formed by plastic material injection molding, Huo Zhesuo The plastic body that rack body 10 includes other assemblies and injection molding is stated, offers terminal on the plastic body of the rack body 10 Slot 11, the connection terminal 30 are shaped in the terminal groove 11.The terminal groove 11 is in the vertical rack body 10 Side extends upward through the rack body 10, and laterally two inner walls of the terminal groove 11 protrude above to form supporting block 12,13 and from institute State the precompressed wall 14 that the top surface of rack body 10 is extended to form towards the terminal groove 11.The supporting block includes being distributed in terminal First, second supporting block 12,13 of 11 front and rear sides of slot, the precompressed wall 14 be located at first, second supporting block 12,13 it Between.14 bottom surface of precompressed wall towards opening direction be equipped with inclined guide surface 15, the inclined guide surface 15 along open at one end by Gradually thicken.

The connection terminal 30 includes taking shape in plate-like base 31 in the rack body 10, from the plate-like base 31 Tearing hole 32 that contact arm 33 made of upper tearing, tear place below the contact arm 33 are formed, from the tearing hole 32 What rear end both lateral sides were stamped and formed out upwards anti-insert protrusion 35 excessively, is stamped and formed out upwards from the 32 front end both lateral sides of tearing hole Hook 34, be opened in the plate-like base 31 32 both lateral sides of tearing hole through hole 36 and be opened in the plate-like base Several location holes 37 on 31.The anti-excessively slotting protrusion 35 is opposite with the tearing direction of the hook 34.

The contact arm 33 include from the plate-like base 31 tearing extend obliquely upward the first elastic arm 331 to be formed, from The second elastic arm 332 that first elastic arm, 331 top extends to form obliquely is rolled over from 332 end of the second elastic arm Curving upwardly extends the contact portion 333 for upwarping portion 334 and being formed in 332 end of the second elastic arm to be formed.The contact Arm 33 is located at 32 top of tearing hole.

After the connection terminal 30 takes shape in the rack body 10, the plate-like base 31 is located at the tearing hole 32 both lateral sides are supported on first, second supporting block 11,12.The tearing hole 32 lateral two of the plate-like base 31 The through hole 36 of side is located at 14 lower section of precompressed wall and corresponds to each other.

Please continue to refer to shown in Fig. 7, Fig. 8, the FPC connecting line 20 includes transmission line 21 and is set on the transmission line 21 Plug-assembly 22.

The plug-assembly 22 includes substrate 221, the transmission line 21 being fixed on the substrate 221 and is covered on the base Drawstring 224 on plate 221.The substrate 221 is hard material, such as pcb board, the surface of 221 middle section of substrate are set There is slot structure 2211.The transmission line 21 is equipped with golden finger 223, and the transmission line 21 equipped with golden finger 223 is fixed on the base In the slot structure 2211 of plate 221, and the golden finger 223 is exposed to 221 surface of substrate.The drawstring 224 includes corresponding to Cutout unit 2241 at 223 position of golden finger, positioned at the sticking part 2242 of 2241 both lateral sides of cutout unit and from institute State the knob portion 2243 that 2242 rear end of sticking part extends rear-suspending.

The sticking part 2242 pastes 221 surface of substrate for being fixed on the golden finger two sides, the substrate 221 and described Fixation hole 2244 is additionally provided on sticking part 2242 so that the sticking part 2242 and the substrate 221 to be preferably fixed together.

In one embodiment, the sticking part 2242 of the drawstring 224 be also possible to be held on the transmission line 21 with it is described Between substrate 221, i.e., the middle section of the described transmission line 21 is golden finger 223, and 223 two sides of golden finger are without golden finger 21 entity of transmission line.

Institute is plugged in please continue to refer to the plug-assembly 20 that shown in Fig. 9, Figure 10, will be described in detail the FPC connecting line 20 State the principle in connection terminal 30.

The plug-assembly 22 inclination insertion connection terminal 30 is first upwarped into 224 lower section of portion, at this point, the plug The bottom surface of the substrate 221 of component 22 is contacted with the plate-like base 31 of the connection terminal 30, and the upper surface of the substrate 221 is limited It is formed on 14 lower section of precompressed wall of the rack body 10, continues to promote the plug-assembly 22 and gradually reduces the plug-assembly The inclined guide surface 15 of 22 gradient, 14 bottom surface of precompressed wall can gradually reduce the gradient of the plug-assembly 22, directly When parallel with the plate-like base 31 to the plug-assembly 22, the plug-assembly 22 is fully inserted into, at this point, the substrate 221 are limited in the anti-of the plate-like base 31 inserts between protrusion 35 and the hook 34 excessively, and the hook 34 can prevent described Plug-assembly 22 exits, and anti-35 protrusions of inserting excessively can prevent the plug-assembly 22 to be excessively inserting and damage contact arm 33.Institute State contact arm 33 contact portion 333 be crimped on downwards it is on the golden finger 223 on 221 surface of substrate and in electrical contact.

When needing to pull out the plug-assembly 22, the knob portion 2243 of the drawstring 224 is lifted up described in making Substrate 221 tilts, until the rear end of the substrate 221 exits from the limitation of the hook 34, can pull back the drawing Band 224.

Another embodiment for please referring to the connection terminal 30 of the application shown in Figure 11, the difference with aforementioned connection terminal 30 exist In: the connection terminal 30 further includes being located at the upward bending of 33 both lateral sides of contact arm from the plate-like base 31 to extend shape At shield and sustain wall 38, the top for shielding and sustain wall 38 extends to form limit component 381 with respect to bending, and the limit component 381 replaces For aforementioned precompressed wall 14, in this embodiment, the top surface of the terminal groove 10 of the rack body 10 no longer needs the precompressed wall 14。

The application connection terminal 30 is shaped in the rack body 10, and the connection terminal 30 is arranged to insert The structure of first 22 plug, maintenance easy to disassemble.

The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal Replacement, improvement etc., should be included within the scope of the claims of this application.
