In a tin-plated product wherein a surface of a substrateof copper or a copper alloy is plated with tin, an underlying layerof at least one of nickel and a copper-nickel alloy is formed on the surface of the substrate, and an outermost layer formed on the surface of the underlying layeris composed of a copper-tin alloy layerand tin layers, the copper-tin alloybeing formed of a large number of crystal grains of a copper-tin alloy, each of the tin layersbeing arranged in a corresponding one of recessed portions, each of which is formed between adjacent crystal grains of the large number of crystal grains of the copper-tin alloy, the adjacent crystal grains being adjacent to each other on the outermost surface of the outer most layer, the area ratio occupied by the tin layerson the outermost surface being 20 to 80%, and the maximum thickness of the tin layersbeing smaller than the average particle diameter of the crystal grains of the copper-tin alloy.

Tin-plated product and method for producing same

A waterproof packing includes: a core member including an electric wire passing part inside and a contacting part for fitting to a mounting side outside; and thermoplastic adhesive adhering to at least the electric wire passing part and the contacting part, wherein the waterproof packing adheres to an electric wire with the thermoplastic adhesive of the electric wire passing part and the waterproof packing adheres to the mounting side with the thermoplastic adhesive of the contacting part by heating. A waterproof connector includes: the waterproof packing; a connector housing for inserting an electric wire having a terminal therein; and a packing receiving part of the connector housing, wherein the waterproof packing is inserted in the packing receiving part as the mounting side.

Waterproof packing, waterproof connector using the same and process for producing waterproof connector

A connector comprises a housing main body , a stopper having a flexibility, and a spacer . The housing main body is provided with a deflection restricting means which with said spacer in contact with said stopper , restricts said stopper from being deflected in the installation direction of said spacer onto said housing main body

Connector

A connector of this invention has a plurality of openings at its rear wall for the insertion of terminals, terminal housing chambers communicating with these openings. Each terminal housing chamber has a pair of flexible arms supported by both the circumferential wall and the front wall of the connector housing, and an engagement member supported at both sides by the flexible arms. The terminal, upon insertion through the openings, engages with the engagement member, being prevented from being pulled out. The terminal housing chambers communicate with connection holes provided at the front wall of the connector. Mating terminals are inserted through the connection holes to be connected to the terminals.

An introduction portion of a resin molded product for introducing a covered conductor is waterproofed in a following method. First, an annular waterproofing member which can be fused with the introduction portion and has a compatibility with its covering portion is attached to an outside periphery of the covered conductor corresponding to the introduction portion. Second, by heating the introduction portion, the waterproofing portion and covering portion are melted together and the waterproofing member and introduction portion are fused together with each other. This method ensures a cheap cost and a high waterproofing performance, and is applicable for various types and sizes of wires.

Waterproofing method for an introduction portion of a covered conductor

A covered wire connection structure is formed by the steps of: pinching a covered wire with a pair of resin chips; pressing and exciting a cover portion of the wire by ultrasonic vibration so as to conductively connect conductive portions of both the covered wires at the connection portion; and melting a pair of the resin chips so as to seal the connection portion. The resin chip comprises main melting portions for pinching the connection portion which are melted to a mating resin chip so as to seal the connection portion, and auxiliary melting portions which are formed of material compatible with the cover portion of the covered wire introduced from the main melting portions and pinch the cover portion such that they are melted to the mating resin chip. The auxiliary melting portions and cover portion of the covered wire are melted together and integrated so as to seal an introductive portion of the covered wire from the resin chips. As a result, a reliability in connecting the covered wires by ultrasonic vibration is maintained and waterproofness in the connection portion is improved.

Connection structure of a covered wire with resin encapsulation

A waterproof structure for a wire leading part of a housing is provided. The structure includes two cover bodies and two waterproof members carried by the cover bodies. The waterproof members are made of elastic materials which are soluble in each other and fusible in insulating covers of wires by ultrasonic oscillation under pressure. At the mutual welding of the cover bodies by the ultrasonic oscillation, the waterproof members are fused in each other, the waterproof members are fused in the insulating covers and the cover bodies are welded to the housing.

Waterproof structure for conductor leading part

A cylindrical waterproof rubber plug to be inserted into a hole formed in a housing is provided. The center of the waterproof rubber plug, has a through-hole into which a wire of outer diameter A is inserted. The plug consists of a main body part and a crimping part of inner diameter B formed integral with the main body part. The dimensions A and B are related by the equation (A-B)/B=0.1.about.0.8. Thus, even when the wire engaged in the plug is obliquely bent, sufficient sealability can be ensured.

Waterproof rubber plug

Copper alloy for use in electrical and electronic parts

A waterproof connector includes a housing having a cavity formed therein, and a male terminal inserted in the housing, the male terminal being connected to a covered wire. A front end portion of a covering of the covered wire of a small diameter is placed on a surface of a base plate, and is clamped. The male terminal, connected to the small-diameter covered wire with a rubber plug, is inserted into the housing, and the rubber plug is fitted in the cavity formed in a rear end portion of the housing. The cavity is formed in the housing in such a manner that a centerline of the cavity is offset from a centerline of the rubber plug in a direction X away from the base plate surface.

Waterproof connector

Disclosure is to provide a terminal for a connector including an engagement mechanism which assures that the terminal can reliably be held in an electrical insulative housing in the engaged state while generating excellent terminal holding force and exhibiting high reliability. The terminal is made of a sheet of metallic material having electrical conductivity and includes an cable connecting portion, a rectangular column-shaped electrical contact portion, engagement pieces formed by cutting and bending a part of one wall of the electrical contact portion in the upward direction, and shock absorbing portions formed by inwardly folding rear edge portions of the engagement pieces. Engagement projections projecting from an insert pin of the connector including an engagement mechanism are brought into contact with the engagement pieces of the terminal with an increased contact area.
