A primary connector (10, 20) includes a primary housing (11, 31) and a number of terminal groups. The primary housing includes a periphery wall (111, 311) and a side wall (112, 312) disposed at opposite sides of the primary housing and extending along a longitudinal direction, a slot (113, 313) defined between the periphery wall and the side wall, and a number of passageways (114, 314) extending along a transverse direction for receiving the number of terminal groups. Each terminal group includes a predetermined terminal (22, 42) having a contact section (221, 421) exposed to the slot and a pair of soldering portions (222, 422) respectively extending from opposite sides of the contact section and inserted outwardly from the periphery wall and the side wall.

In a composite material part having a ceramic matrix and including a fibrous reinforcement which is densified by a matrix consisting of a plurality of ceramic layers having a crack-diverting matrix interphase positioned between two adjacent ceramic matrix layers, the interphase (10) includes: a first phase (12) made of a material conducive to the diversion of a crack reaching the interphase according to a first propagation mode in the transverse direction through one of the two ceramic matrix layers adjacent to the interphase, such that the propagation of the crack continues according to a second propagation mode along the interphase; and a second phase consisting of discrete contact pads (14) that are distributed within the interphase and conducive to the diversion of the crack that propagates along the interphase according to the second propagation mode, such that the propagation of the crack is diverted and continues according to the first propagation mode through the other ceramic matrix layer that is adjacent to the interphase.

The invention relates to an aramid-spandex sheath-core composite fiber and a preparation method thereof. The method is characterized in that a sheath layer spinning solution and a core layer spinning solution are simultaneously extruded in a sheath-core structure and subjected to dry spinning through a spinneret plate assembly of which a spinneret orifice is in a concentric circle form. A sheath layer of the aramid-spandex sheath core composite fiber is made of an aramid 1313 and a core layer is made of spandex; the section of the fiber is of a concentric circle solid structure; the sheath layer accounts for 5-20% of total weight of the fiber; the prepared aramid-spandex sheath core composite fiber has high resilience and also has high temperature resistance, chemical resistance and wear resistance; and meanwhile, the problems that the sheath layer aramid 1313 fiber is not easy to dye, the sheath-core composite fiber is difficult to spin and mold and the contact interface of the sheath layer and the core is easy to peel off are solved.

The present invention provides an array substrate, the peripheral circuit area of ​​which includes a peripheral region substrate, a peripheral region TFT layer, a peripheral region passivation layer, a color resist layer, a peripheral region PFA layer, and a connecting line layer arranged in sequence from bottom to top. The resistance layer is provided with a first via hole, and the PFA layer in the peripheral area is correspondingly provided with a second via hole in the first via hole, and the hole wall of the second via hole belongs to the PFA layer in the peripheral area, and the peripheral area The passivation layer is correspondingly provided with a third via hole connected to the second via hole under the second via hole, and the corresponding second via hole and the third via hole together form a transfer via hole, and the connecting line The layer is in contact with the TFT layer in the peripheral area through the transfer via hole, and the color resistance layer is set between the passivation layer in the peripheral area and the PFA layer in the peripheral area, and the via hole for transfer in the PFA layer in the peripheral area is set in the color In the barrier layer, the adhesion of the PFA layer in the peripheral area can be improved, and the risk of peeling off of the PFA layer in the peripheral area can be reduced, thereby improving the yield of PFA products.

The invention discloses a miniature acoustic generator and relates to the technical field of an electroacoustic product. The miniature acoustic generator comprises a shell and a front cover which are combined together. A vibration system and a magnetic circuit system are contained in a space enclosed by the shell and the front cover. The vibration system comprises vibration diaphragm of which edge part is fixed between the front cover and the shell. The front cover is equipped with a side wall. The edge part comprises a fixing part located at an inner side and a turnup which is located at the outer side of the fixing part and bends upwards. The turnup is fixed on the outer surface of the side wall. According to the miniature acoustic generator, the technical problem that in the prior art, the waterproof performance of the miniature acoustic generator is poor is solved. The miniature acoustic generator is good in waterproof performance, high in waterproof stability and reliability, good in acoustic performance and long in service life.
