Abstract
Description
Technical Field
[0001] This application relates to the technical field of wire connectors, and particularly relates to a connector that can prevent condensation. Background Art
[0002] TPA. In a connector, TPA is the abbreviation of Terminal Position Assurance. In the field of connectors, TPA is mainly used to fix the terminal position, ensure that the terminals are reliably fixed inside the connector, and thus improve the overall performance and reliability of the connector.
[0003] FFC, whose full name is Flexible Flat Cable, is also known as Flexible Printed Circuit or Flexible Cable Assembly. It is a cable product with high flexibility, high reliability and foldable and bendable performance. It is usually made of insulating substrate and conductive copper foil or gold-plated copper foil. Through the lamination process, the copper foil is tightly bonded to the substrate, and the required circuit pattern is etched on the copper foil.
[0004] Generally, a connector includes a board end, a wire end and FFC wire. Among them, the terminals at the board end are used for electrical connection with the FFC wire. Since the connector needs to perform plugging and unplugging operations with the FFC wire, the terminals are exposed to the atmosphere. When the surrounding environment has a high humidity, if the surface temperature of the contact conductive area of the terminal is lower than the dew point temperature of the surrounding air, water vapor will condense into water droplets on the surface of the connector, forming condensation. Long-term accumulation of condensation will cause the corrosion of the contact conductive area of the connector to intensify and the performance to decline.
[0005] Therefore, finding a suitable connector structure is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model
[0006] Based on this, it is necessary to propose a connector that can prevent condensation to solve the problem that the contact conductive area of the terminal in the prior art is prone to form condensation.

[0011] In one implementation, the TPA includes a long support part adapted to the width of the FFC wire, a first limiting end and a second limiting end for limiting the FFC wire from moving left and right.

The first rib and the second rib are arranged on the same straight line, and there is a clearance for avoiding the block of the second housing part between the first rib and the second rib.
[0012] In one implementation, the first rib is the same as the second rib.
[0013] In one implementation, the first rib and the second rib are integrally formed with the TPA.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.
[0028] Generally, a connector includes a board end, a wire end, and an FFC wire. The terminals at the board end are used for electrical connection with the FFC wire. Since the connector needs to be plugged and unplugged with the FFC wire, the terminals are exposed to the atmosphere. When the surrounding environment has a high humidity, if the surface temperature of the contact conductive area of the terminal is lower than the dew point temperature of the surrounding air, water vapor will condense into water droplets on the surface of the connector, forming condensation. Long-term accumulation of condensation will cause the corrosion of the contact conductive area of the connector to intensify and the performance to decline.
