Abstract

The utility model relates to a terminal module and an electric connector using the same. For the terminal module, terminals are formed by stamping, and the terminals are fixed by injection molding. The terminal module includes multiple terminals and at least one fixing member. Each terminal is formed into one body by stamping, and is provided with a fixing part, an elastic arm which extends from one side of the fixing part, and a welding part which extends from the other side of the fixing part. The elastic arm extends forward to form a contact part. The longitudinal depth of the contact part is bigger than the transverse width of the contact part. The fixing part is circularly arranged on the fixing part of each terminal in an injection molding way, and the terminals are fixed into two rows by the fixing member. After the terminals are directly formed by stamping, the terminals are fixed in an injection molding way, and the terminals can have the excellent structural strength. Besides, the terminals are connected and fixed in an injection molding way, so the electric connector assembling time is greatly shortened, and the high speed signal transmission can be carried out.

Description

Terminal module and use the electric connector of this terminal module

Technical field

The utility model is relevant for a kind of terminal module that is applied on electric connector, refers to especially a kind of terminal module that utilizes the terminal after punch forming to utilize injection molding method to be fixed.

Background technology

Electric connector is a kind of transmission medium of the signal of telecommunication, is mainly to utilize terminal as the transmission between the signal of telecommunication.In general, electric connector mainly is arranged on circuit board, as the expansion of ancillary equipment, as memory module etc.

Existing being used for is connected in electric connector on circuit board with memory module, is commonly called as DDR, and roughly distinguishing has two kinds of kenels, and a kind of is vertical DDR, and a kind of is horizontal DDR.So-called vertical DDR after inserting electric connector exactly, forms stand-type meaning and namely is formed with an angle with circuit board.And after horizontal DDR inserts electric connector exactly, be parallel to each other with circuit board.In vertical DDR use, easily cause the waste in space, therefore on the electronic product in less space, with rare, mostly replaced by horizontal DDR.

Present common horizontal DDR electric connector, the general differentiation has two classes again, is mainly to be distinguished by the molding mode of metal terminal, and a kind of is plug-in type, and another kind is bendable.

As shown in Figure 1, be a kind of schematic diagram of plug in terminals.As shown in the figure, described plug in terminals A, mainly one-body molded by impact style, this kind plug in terminals A forms an inserting part B on plug in terminals A, and the upper lower edge at inserting part B has protruded out a hangnail C at least, after seeing through inserting part B insertion insulation shell (expression in diagram), utilize hangnail C to thrust in plastic casing, and then reach fixing effect.

But, this kind plug in terminals A is when carrying out the signal transmission, when signal transmits by terminal, can cause signal to branch in inserting part B, thereby in the process that signal is transmitting, can't directly pass through fast plug in terminals A, and be delivered on circuit board, therefore this kind plug in terminals only can provide the electric connector of general transmission speed to use, and can't use in the electric connector of high-speed transfer.

See also shown in Figure 2ly, be a kind of schematic diagram of bendable terminal.As shown in the figure, described bendable terminal D is mainly after utilizing the impact style moulding, then in the pressing and bending mode, after bending went out required form, the mode of recycling ejection formation was linked described bendable terminal D.

But, this kind bendable terminal D, the mode that need to see through bending can reach the effect of moulding.But, because metal itself has certain stress,, easily produce stress and the phenomenon such as concentrate in Forging Process when terminal; Moreover, because metal itself has certain ductility, during greater than the ductility of metal material itself, easily cause the phenomenon of resilience when the strength of exerting pressure in Forging Process, cause the evenness of described injection-molded terminal relatively poor, and the phenomenon of distortion is also easily arranged.Especially in assembling process, easier because assembling accidentally cause collision, and cause the distortion of terminal.

This kind mode easily causes bad on processing procedure, has not only affected process rate, causes the raising of fraction defective, more can cause the increase on manufacturing cost.
