Abstract

An electrically connected coupling or socket structure includes a lower housing embedded under an upper housing; at least a pair of pin holes is arranged on the upper portion of an inner chamber of the upper housing; the lower portion of the upper housing is provided with an installing chamber with respect to the pin hole; the pin hole is communicated with the installing chamber; the installing chamber is equipped with a contact sheet; bending shrapnel tongues are arranged on one end of the contact sheet on left and right sides; a closed end of the shrapnel tongue is connected with the contact sheet; an opening end of the shrapnel tongue keeps a certain distance from the contact sheet; in the natural state, the distance between two shrapnel tongues on the contact sheet is smaller than the thickness of the pin; when the pin is sleeved with the contact sheet, the opening ends of two shrapnel tongues arranged on the contact sheet perform an elastic deformation under the pressure of the pin, thus making the pin and the shrapnel tongue abut together and ensuring a good contact between the pin of the socket and contact sheet. The utility model has characteristic of simple and reasonable structure, long service life and high safe coefficient.

Description

The coupling or the socket that are electrically connected

Technical field

The utility model relates to a kind of coupling or socket of electrical connection, is particularly useful on the household electrical appliance such as soy bean milk making machine.

Background technology

At present, electric contact piece on the market on being seen coupling or socket, the plate, mainly be that copper sheet with an integral body is made, strain is little, because be rigid distortion, the distance of leading the left and right sides on the electric contact piece strengthens after attaching plug is plugged, and makes attaching plug and electric contact piece loosening, through repeatedly making poor electric contact after the attaching plug plug, cause outage or seriously can cause fire.Chinese patent literature CN101299489A discloses a kind of wire connector on November 5th, 2008, it is characterized in that wire connector includes connector body, fixedly assistor, insertion assistor combine; Connector body is made up of header body, jack body and shell bonnet; Fixedly assistor is made up of locking member, waterproof part and tightening device; Inserting assistor is made up of insertion sheet, dividing plate, base.It is said that it makes electric wire simply easy with docking of wire connector by being provided with connector body, the fixedly design of assistor, insertion assistor, saves time, high efficiency can significantly reduce the electric wire outage, and the working site keeps clean.But its complex structure, manufacturing cost are high and assemble cumbersomely, therefore, are necessary to be further improved and perfect.

The utility model content

The purpose of this utility model be intended to provide a kind of simple and reasonable, contact is reliable and the coupling or the socket structure of the electrical connection of long service life, to overcome weak point of the prior art.

Press the coupling or the socket of a kind of electrical connection of this purpose design, comprise the lower casing that embeds the upper casing below, its architectural feature is that the top of upper casing inner chamber offers at least one pair of pin holes, the bottom of upper casing is provided with and the corresponding installation cavity of pin holes, pin holes and installation cavity connect, and are equiped with the contact chip of shell fragment tongue in the installation cavity.

One end of described contact chip is provided with bending edges, and at least one side bending edges is provided with the shell fragment tongue of bending, and the blind end of shell fragment tongue links to each other with contact chip, and the open end and the contact chip of shell fragment tongue are provided with spacing.

One end of described contact chip is provided with bending edges, is respectively equipped with the shell fragment tongue of bending on the bending edges of the left and right sides, and the blind end of shell fragment tongue links to each other with contact chip, and both sides shell fragment tongue is similar Y shape or X-shaped or positive and negative C shape; Shell fragment tongue stage casing, both sides contacts or spacing is arranged.

The other end of described contact chip is provided with the tail end that is used to connect lead-in wire, and tail end is a sealing wire, perhaps is terminal, and perhaps the terminal with other electric elements plugs.

Described contact chip is made with the thin plate section bar of beryllium copper or the thin plate section bar of phosphor-copper; The shell fragment tongue is for to be stamped to form on bending edges.

The top of described upper casing is provided with pin, and pin and contact chip socket-connect.The quantity of pin and contact chip respectively is six, and two rows are uniform up and down.

The utility model since under nature the distance between two shell fragment tongues on the contact chip less than the thickness of pin, when pin and contact chip socket-connect, under the pressure of pin, the open end that is arranged at two shell fragment tongues on the contact chip can be fulcrum with the blind end, carry out strain, pin is close together tightly mutually with the shell fragment tongue, thereby the pin that guarantees socket contact well, improves useful life and coefficient of safety with contact chip.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 1-9, coupling of this electrical connection or socket, comprise the lower casing 3 that embeds upper casing 2 belows, the top of upper casing 2 is provided with pin 4, the top of upper casing 2 inner chambers offers three pairs of pin holes 2.1, the bottom of upper casing 2 is provided with and pin holes 2.1 corresponding installation cavitys 2.2, and pin holes 2.1 connects with installation cavity, is equiped with contact chip 1 in the installation cavity 2.2.

The described contact chip 1 one end left and right sides are respectively equipped with the shell fragment tongue 11 of bending, and the blind end 113 of shell fragment tongue links to each other with contact chip 1, and the open end 112 of shell fragment tongue 11 keeps certain distance with contact chip 1.Because the distance between two shell fragment tongues 11 on the contact chip 1 is less than the thickness of pin 4 under nature, when pin 4 and contact chip 1 socket-connect, under the pressure of pin 4, the open end 112 of shell fragment tongue 11 can be a fulcrum with blind end 113, carry out strain, pin 4 is close together tightly mutually with shell fragment tongue 11, thereby guarantees that contact is good.
