Jae Taiwan Ltd. and Japan Aviation Electronics Ind. Ltd. | Date: 2013-01-24

A connector is fixable to an object such as a printed circuit board. The connector comprises a shell having a body portion and two fixed portions for fixing the body portion to the object. The body portion has two side portions and an upper portion coupling the side portions with each other in a lateral direction. The side portions are connected to the respective fixed portions. The fixed portion has a base portion and a strengthener. The base portion is located outward of the side portion in the lateral direction. The strengthener extends inward in the lateral direction from the base portion beyond the side portion.

A USB connector comprises a special USB plug and a USB receptacle mateable with the special USB plug. The special USB plug has a plug ground contact and a plug contact portion as a part of the plug ground contact. The USB receptacle has a plurality of contacts including a ground contact, a detector and a holding member. Each of the contacts has a contact point. Especially the ground contacts has the contact point configured to be brought into contact with the plug ground contact while the detector has a detecting portion configured to be brought into contact with the plug contact portion. The holding member has a plate portion formed with a principal surface. The holding member holds the contacts so that the contact points project from the principal surface of the plate portion while holding the detector so that the detecting portion projects from the principal surface of the plate portion. A distance between the detecting portion and the contact point of the ground contact is smaller than a distance between the detecting portion and the contact point of the contact other than the ground contact.

A connector comprises a receiving portion, a housing and an actuator. The housing has a lock portion protruding upward and a recess formed with a bottom portion. The actuator has a pressing portion. The actuator is supported by the housing so as to be pivotable between an open position and a close position. When the actuator is located at the open position, a plate-like or sheet-like object comprising an interposed portion and a locked portion, for example, a Flexible Printed Circuit (FPC), is inserted and received in the receiving portion. When the object is received in the receiving portion, the interposed portion is located above the recess, and the locked portion is located rearward of the lock portion. The pressing portion and the bottom portion interpose the interposed portion of the object when the actuator pivots from the open position to the close position.

A reliability of a new film-type connection is investigated and compared to a conventional anisotropic conducting adhesive technology, e.g., an anisotropic conductive film (ACF) joint by measuring the contact resistance through environmental tests and flexibility tests. A film-type connector which thickness less than 0.1 mm is composed of a base material such as polyimide, an adhesive layer which deforms elastically against pressure, and electrodes arranged on the adhesive layer. Results of the test show that the film-type connection has some advantages compared to the ACF joint in mildness of the connecting condition and the contact resistance stability. Source

With the escalating demands for downsizing and functionalizing mobile electronics, flexible electronics have become an important aspect of future technologies. To address limitations concerning junction deformation, we developed a new connection method using a film-type connector that is less than 0.1 mm thick. The film-type connector is composed of an organic film substrate, a UV-curable adhesive that deforms elastically under pressure, and electrodes that are arranged on the adhesive. The film-type connection relies on a plate-to-plate contact, which ensures a sufficient contact area. The electrical reliability of the film-type connection was investigated based on changes in the resistance during bending at curvature radii of 70, 50, 25, 10, 5, and 2.5 mm. The connection was bent 1000 times to investigate the reproducibility of the connector’s bending properties. The tests showed that no disconnections occurred due to bending in the vertical direction of the electrode, but disconnections were observed due to bending in the parallel direction at curvature radii of 10, 5, and 2.5 mm. In addition, the maximum average change in resistance was less than 70 milliohms unless a disconnection was generated. These results support the application of the new film-type connection in future flexible devices. © 2015 by the authors; licensee MDPI, Basel, Switzerland. Source
