Abstract

The utility model provides an electrical connector, which comprises a seat body, a first shell and a second shell. A terminal set is inserted into a jointing part of the seat body. A splicing trough is formed around the jointing part. Cable accommodation troughs are formed on the rear side of the seat body, and are electrically connected with preset flexible flat cables. The terminal set can be extended out of the cable accommodation troughs. The first shell is covered and positioned outside the seat body. A hollowed part for exposing the jointing part is formed on the surface of the first shell, and the periphery of the hollowed part is enclosed. In addition, the second shell is covered and positioned outside the seat body and the first shell. The first shell is integrally formed by a metal sheet, so that the electrical connector has relatively stronger structural strength. The thickness of the first shell is not required to be decreased for a crimping procedure, so that excessive extrusion deformation caused by punching and continuous bending processes of a crimping way or assembly positioning inaccuracy caused by insufficient riveting can be prevented.

Description

Electric connector

Technical field

The utility model relates to a kind of electric connector; Especially the docking section that refers to pedestal is equipped with terminal group; And present external cover is covered with integrated housing and has better structural strength, can prevent that the crimping mode from causing assembling to locate untrue situation to send out the survivor because of producing distortion or riveted quantity not sufficient in punching press, the bending process.

Background technology

Electronics technology is fast-developing now, and electronic products such as computer, notebook computer or mobile phone all have been prevalent in society and have gone up each corner; And at present design of electronic products all trend towards gently, thin, short, little, and in order to make various electronic product volume-diminished, so; The structure of the electronics spare part on the electronic product internal circuit board; Then need more microminiaturization and precision, overall construction intensity also needs to strengthen, with in response to electronic product development trend at present.

Moreover; Because the height that working transmission is very huge and frequency is suitable between electronic product and the panel; General Low Voltage Differential Signal (the Low Volt Age Differential Signal that all can adopt characteristics such as having ultrahigh speed, low-power consumption reaches low electromagenetic wave radiation; LVDS) connector is reached with the panel (Panel) more than 17 inches such as notebook computer, LCD TV, LCD screen and is formed electric connection, and the panel below 15 inches is mainly used flexible circuit board (Flexible Printed Circuit, FPC) connector; Along with the connector volume requirement is more and more small, just develop the connector that various different types.

See also shown in Figure 5; It is the stereo appearance figure of existing electric connector; Find out by knowing among the figure, wherein be equipped with complex conduction terminal B on the docking section A1 of this plastic cement body A institute tool, and the A1 perimeter is formed with an inserting groove A2 in the docking section; Can the plural buckle C1 of interior iron-clad C institute tool be gone up corresponding snap groove A3 with plastic cement body A fastens each other; And the side plate C2 of iron-clad C side edge is embedded in the buckle groove A4 in making, and the protruding button A5 at button hole C3 on the side plate C2 and buckle groove A4 internal face place fastens each other, and the plural shell fragment C4 of interior iron-clad C perimeter then is inserted into respectively in the inserting groove A2.

When the plate terminal adapter is done timing; Just can rely on plural shell fragment C4 to be held on the plate terminal adapter; And then the fixing strength of increase plate terminal adapter, the difficult situation of becoming flexible or deviating from that produces takes place, the direct and plastic cement body A crimping moulding of iron-clad C general using machining machine and tool in thought is somebody's turn to do; Go up position limiting structure even can form a backstop after the originally upright inside punching press of metal sheet, the continuous bending in plastic cement body A as anticreep; So interior iron-clad C thickness must be given attenuation, just can be beneficial to machining machine and tool and carry out crimping, riveted, and also must be suitable in the crimping process in side plate C2 is embedded in buckle groove A4 downwards precisely; Otherwise be easy to generate excessive crimp; Or take place because of the riveted quantity not sufficient causes the protruding button A5 at button hole C3 and buckle groove A4 internal face place on the side plate C2 can't fasten, assemble the untrue situation in location, and the whole structural strength of iron-clad C in reducing designs again and solves and remain to be engaged in this journey dealer.

So; Utility model designer is because problem and the disappearance that existing electric connector uses; Be to collect related data via assessing in many ways and consider, and utilize the research and development experience for many years of engaging in the industry constantly to study and revise, the beginning is designed the novel birth of this kind electric connector.

Summary of the invention

Deficiency to prior art; The purpose of the utility model is: a kind of electric connector is provided; Solve the excessive crimp of recurrent generation that prior art exists, or can't fasten, assemble the untrue problem of locating because of the riveted quantity not sufficient causes button hole and the protruding button at buckle groove internal face place on the side plate.
