The invention relates to an electrical contact, in particular an electrical socket contact (1), having a catch spring (112) projecting therefrom for latching the electrical contact (1) in a housing, wherein over substantially its entire extent in the direction of a longitudinal axis (L) of the electrical contact (1), the catch spring (112) is assembled with regard to its cross-section (Q) from at least two areas (113, 115), which are arranged bent relative to one another by means of a transitional area (114) or are connected together in such a manner that they merge continuously.

An image forming apparatus includes a turning unit that turns the recording medium fed from a fixing unit, which fixes toner transferred to a recording medium and has a heating roller for heating toner, by approximately 90° with respect to a feeding direction of the recording medium, and a discharge roller that discharges the recording medium turned by the turning unit. A circumferential speed of the discharge roller is smaller than a circumferential speed of the heating roller.

The invention provides a lead-core rubber support component with a friction pair, comprising a lead-core rubber support body, an upper external connecting steel plate and a lower external connecting steel plate which are respectively arranged on the upper end surface and the lower end surface of the lead-core rubber support body, and one-two friction pairs; the upper end surface and the lower endsurface of the support body are respectively connected with the upper external connecting steel plate and the lower external connecting steel plate by a screw and a shearing bond; and one auxiliary surface of each friction pair is respectively arranged on the external upper surface of the upper external connecting steel plate or the lower external surface of the lower external connecting steel plate or arranged at the external upper surface of the upper external connecting steel plate and the lower external surface of the lower external connecting steel plate simultaneously. The installation and use method of the component comprises the steps as follows: the component is arranged between a bridge beam body and a bridge pier; the other auxiliary surface of each friction pair is respectively arranged on the lower surface of the bridge beam and the bridge pier or arranged on the lower surface of the bridge beam and the bridge pier simultaneously; and after creep and shrink of the bridge beam are basically completed, the lead-core rubber support component is fixedly connected with the bridge beam and the bridge pier, thus eliminating the initial deformation of the support caused by the creepage and shrink of the concrete of the bridge beam.

Embodiments of the present invention provide a support structure for supporting a flexible display and a flexible display device, which relate to the field of display technology. When the flexible display device is curled, while ensuring the uniform distribution of the stress of the flexible display, it not only prevents the support layer from breaking, Also improve the flatness of the flexible display. The support structure includes a flexible support layer, the flexible support layer includes a first support layer and a second support layer; the first support layer includes a first surface and a second surface oppositely arranged, and the first surface is the first surface of the first support layer facing the flexible display screen. The surface; the second support layer is located on one side of the second surface of the first support layer, the second support layer includes a plurality of support portions arranged at intervals, the support portion includes a first support portion and a second support portion, and the first support portion The direction pointing to the second supporting part is the rolling direction of the flexible display; in the direction perpendicular to the plane where the first supporting layer is located, the film thickness of the first supporting part is greater than that of the second supporting part.

The invention discloses a manufacturing method of a steel wire with an alloy plated layer, the steel wire and a steel wire rope, and relates to the technical field of manufacturing and production of steel wires. The manufacturing method of the steel wire comprises the following steps that 1, a steel wire matrix is obtained; 2, the obtained steel wire matrix passes through a zinc pot with molten zinc liquid to obtain a steel wire matrix plated with a zinc layer, the steel wire matrix plated with the zinc layer is subjected to mechanical wiping treatment, and the steel wire matrix with an iron-zinc alloy layer on the surface or the steel wire matrix with the iron-zinc alloy layer and a pure zinc layer on the surface is obtained; 3, the obtained steel wire matrix with the iron-zinc alloy layer on the surface is pickled to remove the pure zinc layer on the surface of the steel wire matrix, and the steel wire matrix with the iron-zinc alloy layer on the surface is obtained; and 4, the obtained steel wire matrix with the iron-zinc alloy on the surface is drawn to obtain the steel wire with the required size. The steel wire produced by the method is beneficial to improving drawing and twisting speed and improving production efficiency.

PROBLEM TO BE SOLVED: To provide a memory card connector capable of reliably preventing, with a simple structure, the insertion of a memory card in an improper posture, without carrying out any work on a case.SOLUTION: A leaf spring piece supported in a cantilevered manner is formed integrally with a cover. An erroneous insertion prevention plate on at least a free-end side of the leaf spring piece is inclined downward with respect to the cover such that a rear lateral surface of the erroneous insertion prevention plate faces the inner side of a card housing part in a manner perpendicular to an inserting direction of a memory card and crosses a movement track of an inclined surface of the memory card inserted in the card housing part. If the memory card is inserted in a regular posture, the inclined surface abuts on a lower portion of the rear lateral surface and pushes up the erroneous insertion prevention plate, but if the memory card is inserted in an improper posture, a flat surface abuts on the rear lateral surface, thus causing the erroneous insertion prevention plate to restrict the insertion of the memory card.
