A fixing structure of a connector female seat and a circuit board, provided by the present invention, comprises a base body, a circuit board and a clamping member, the circuit board is provided with a first clamping plate, the base body is provided with a first positioning groove, the first positioning groove is also internally provided with a second clamping plate and a first limiting plate which are fixedly connected with the base body, and a gap exists between the second clamping plate and the base body. The first clamping plate is partially inserted into the first positioning groove and clamped with the second clamping plate, one end of the circuit board abuts against the first limiting plate, the other end of the circuit board abuts against the bottom wall of the first positioning groove, a second limiting plate is arranged on the clamping piece, the clamping piece is clamped with the base body, and the second limiting plate is contained in the gap. One end of the second limiting plate abuts against the second clamping plate, and the other end of the second limiting plate abuts against the side wall of the first positioning groove. The circuit board and the base body are firmly connected through clamping, deformation of the second clamping plate is limited through the second limiting plate, and the clamping strength between the circuit board and the base body is increased, so firm connection between the circuit board and the base body is kept.

The invention relates to a closed zipper tooth and a closed shielding zipper. The closed zipper tooth comprises first teeth, second teeth and a cloth seam, the first teeth and the second teeth are fixedly arranged in a staggered mode, and a meshing cloth seam groove is formed in the front end, in the thickness direction, of a first tooth meshing head and the front end, in the thickness direction,of a second tooth meshing head after fixation; the closed shielding zipper comprises a puller, a left cloth tape, a right cloth tape, left zipper teeth, right zipper teeth and a locking piece, the left zipper teeth and the right zipper teeth are the staggered closed zipper teeth, the left zipper teeth are clamped on the left cloth belt, and the right zipper teeth are clamped on the right cloth belt; the left zipper tooth meshing convex parts of the left zipper teeth are mutually clamped with the right zipper tooth meshing grooves of the right zipper teeth, and the right zipper tooth meshing convex parts of the right zipper teeth are mutually clamped with the left zipper tooth meshing grooves of the left zipper teeth. According to the zipper teeth and the zipper composed of the zipper teeth, the space between the zipper teeth, the space between the zipper teeth and the cloth belt and the space between the zipper teeth and the zipper puller are all completely sealed, and the full-sealingfunction of the zipper is effectively achieved; the zipper is high in connection strength and rich in aesthetic feeling.

An operation lever includes a lever main body A having a tapered insertion portion (1) which has locking portions (11) and in which the size in the up-down direction decreases gradually and an operation knob B having a tapered insertion hole (3)in which a size in the up-down direction decreases gradually from an opening (3a) toward a deep end wall surface (3b). The insertion hole (3)includes tapered reference surface (31)facing each other in the up-down direction. Grooves (33)are formed from the opening and along the deep end wall surface (3b) so as to protrude outward from the respective tapered reference surfaces (31) and the inner side surfaces in the insertion hole of the operation knob. The insertion portion (1) is inserted into the insertion hole (3)and the locking portions (11) bite in outward through the respective tapered reference surfaces(31).

A zipper tape is in an elongated shape and includes, in a cross-sectional shape, a pair of base strips and engagement portions projecting from surfaces facing each other of the pair of respective base strips, the engagement portions being engageable with each other. At least the engagement portions are each formed of a first biodegradable resin composition having a yield strain of 3.4% or more during a tensile test.

The invention relates to a recliner for a motor vehicle having a wedge capable of controlling the inclination of the vehicle seat backrest. In particular, the invention relates to a recliner for a motor vehicle having a wedge which improves the play and strength of the recliner.

The present invention proposes a fixing structure between a connector base and a circuit board, including a base body, a circuit board, and an engaging member. The circuit board is provided with a first engaging plate, and the base body is provided with a first positioning groove. There is also a second engaging plate and a first limiting plate fixedly connected to the base body, there is a gap between the second engaging plate and the base body, the first engaging plate is partially inserted into the first positioning groove and engaged with the second engaging plate, One end of the circuit board abuts against the first limiting plate, the other end of the circuit board abuts against the bottom wall of the first positioning groove, a second limiting plate is provided on the engaging part, the engaging part engages with the base body and the second limiting plate The positioning plate is accommodated in the gap, one end of the second limiting plate abuts against the second engaging plate, and the other end of the second limiting plate abuts against the side wall of the first positioning slot; The connection is to limit the deformation of the second engaging plate through the second limiting plate to increase the engaging strength between the circuit board and the base body, thereby maintaining a firm connection between the circuit board and the base body.

The invention discloses a lock wire contact piece for preventing screw from coming out, which includes a contact piece, a pin, a square nut and a screw. In the cavity of the square nut, when the screw is loosened, the flange prevents the screw from coming out of the threaded hole of the square nut. When the screw is locked, the contact piece inserted into the square nut blocks the through hole on the square nut, and the screw Also can't escape from the through hole; the present invention adopts the thickening layer arranged on the square nut, and the threaded hole is arranged on the thickening layer, ensures the effective number of turns of the screw thread on the threaded hole, thereby strengthens the engagement of the screw and the threaded hole Strength, improving the connection reliability of the lock wire contact.
