摘要： A connector includes a joint including a hollow plug with a first electrode formed on an internal surface and a second electrode formed on an external surface. The joint is connected with a transformer. A first housing defines a first hole, a second hole and a third hole for receiving the hollow plug of the joint. A first plug with a first electrode and a second electrode is insertable through the first hole defined in the first housing. A second plug with a first electrode and a second electrode is insertable through the second hole defined in the first housing. A metal pin is connected with the first electrodes of the first and second plugs. A first J-shaped metal strip includes a first end portion connected with the second electrode of the first plug and a second end portion engageable with the second electrode of the plug of the joint. A second J-shaped metal strip includes a first end portion connected with the second electrode of the second plug and a second end portion engageable with the second electrode of the plug of the joint. A second housing defines a first hole, a second hole, a third hole and a fourth hole. The first housing is slidably receivable in the second housing. Either the first plug is insertable through the first hole defined in the second housing or the second plug is insertable through the second hole defined in the second housing. The hole defined in the first housing is in communication with either the third hole or the fourth hole defined in the second housing.

摘要： A connector jack including a molded retainer, a conducting pin centrally located within the molded retainer, and a resilient clamping element. The molded retainer is a cylindrical body having a central recess at its front end for receiving an annular prong of a plug, two slots at its rear end thereof for receiving the resilient element, and a central stepped recess at its rear end and a perforation for receiving the conducting pin. The resilient clamping element has a conducting leg, a fixing leg and a T-shaped stem which connects the two legs. The two legs are insertable into the slots respectively. The conducting leg further includes a semicircular-shaped conducting end at its inner side which projects over the slot into the central recess.

摘要： A safety cover for sockets includes a cover body having a recess in a first side thereof and two spaced blades extending outward from the recess and being perpendicular to the cover body. The blades are adapted to engage with two slits of a socket. A clip extends from the cover body and pivotable at an end thereof adjacent to the cover body. The clip includes a pair of substantially L-shaped members each with a flexible distal end extending toward each other to define a passage having width slightly less than that of a wire of the plug, such that the safety cover clips on the wire of the plug when not in use. The distance between the L-shaped members is less than that between the blades. The cover body includes two cutouts to allow a pivotal movement of the L-shaped members into the recess. The recess has two spaced protrusions extending outward from a periphery thereof which is opposite to the cutouts to retain the L-shaped members when the clip is stored in the recess.
摘要翻译：用于插座的安全盖包括在其第一侧具有凹部的盖体和从凹部向外延伸并垂直于盖体的两个间隔开的叶片。叶片适于与插座的两个狭缝接合。夹子从盖体延伸并且在与盖体相邻的端部可枢转。夹具包括一对基本上L形的构件，每个构件具有朝向彼此延伸的柔性远端，以限定具有略小于插头线的宽度的通道，使得安全盖夹在插头的线上不用时。 L形构件之间的距离小于叶片之间的距离。盖体包括两个切口，以允许L形构件枢转运动到凹部中。所述凹部具有两个间隔开的突出部，其从与所述切口相对的周边向外延伸，以在所述夹子存储在所述凹部中时保持所述L形部件。

摘要： An optical fiber connector has a tubular housing which has a slot formed through a corresponding upper periphery and lower periphery thereof. A securing plate is allowed to be positioned inside the slot with two distal ends thereof substantially protruding slightly out of the slot. A substantially elliptical hole is formed at the center of the plate with the longer axis thereof in substantially horizontal direction allowing to be penetrated by a fiber.
