Abstract

The utility model provides an electric connector and a terminal set thereof. A base of an insulating seat is provided with multiple accommodating channels in a recessed manner. A butt-joint part at one side of the base is provided with multiple terminal grooves, communicated with the accommodating channels, in a recessed manner. The terminal set has a base part that is positioned in the accommodating channels. A side part of the base part is upwardly bent to form a first bending sheet. A second bending sheet is formed by bending downwardly from the first bending sheet and is extended forwardly in the same direction to form an elastic arm which is extended into the terminal grooves. The other side part of the base part opposite to the first bending sheet is upwardly bent to form a third bending sheet. In this way, the expansion width of the terminal set before molding is equal to the width after continuous stamping bending molding, so that the terminal set and a material strap under the connection state are directly assembled into the insulating seat by one step, thereby improving the efficiency of the integral assembling operation.

Description

Electric connector and terminal group thereof

Technical field

The utility model provides a kind of electric connector and terminal group thereof, espespecially the width size behind the width of the front flattening of terminal group moulding and the continous way punching press bending forming is constant, terminal group and strip one-time-reach-place can be assembled in the insulating base frame, to promote the efficient of overall package operation.

Background technology

Electronics technology is fast-developing now, make the electronic installations such as computer, notebook computer, liquid crystal display all be prevalent in upper each corner of society, and because at present electronic installation design all trends towards light, thin, short, little, so, a plurality of cables of electronic installation inside are connected the assembling space that can utilize and also just more and more are tending towards narrow with circuit board, and the general practice all can by wire pair board connector reach and circuit board between electric connection, along with the connector volume requirement is more and more small, just develop the connector of various different types.

See also Fig. 8, Fig. 9, shown in Figure 10, it is the stereo appearance figure for existing conducting terminal, front view before the moulding and the front view after the moulding, find out by knowing among the figure, should existing conducting terminal A be by metal lamellar body punching press institute bending forming wherein, and has a terminal body A1, and terminal body A1 two side places are provided with the side arm A2 of relative extension, its two side arm A2 respectively bending downwards is extended with contact arm A21, and be provided with the connecting portion A3 of tool crimp groove A31 in terminal body A1 and side arm A2 junction, and also be provided with the connecting portion A4 of tool crimp groove A41 with respect to the in addition side place of connecting portion A3.

Only should on using, reality still have many shortcomings by existing conducting terminal A, because wider part was to reach the extended contact arm A21 again by side arm A2 by the extended side arm A2 of the joint portion A3 of the U-shaped crimp groove A31 of tool after conducting terminal A flattened, and conducting terminal A is that the metal lamellar body is via continous way punching press institute bending forming, each conducting terminal A all need to be connected by a strip A0, but wider width when flattening because of conducting terminal A, and the spacing d2 of the spacing d1 that each conducting terminal A is adjacent behind the punching press bending forming can't shorten, when conducting terminal A is assembled in plastic body inside, if the width spacing between the adjacent slotted eye (not shown) of each on the plastic body is less than a plurality of conducting terminal A spacing d2 sizes, then will cause under the conducting terminal A of continous way punching press bending forming and the strip A0 connection status and can't once be inserted in plastic body inside, must single conducting terminal A assembling or branched conducting terminal A carry out the interval assembling institute assembling pressing number of times of deriving and become many, the assembling operation efficient also problem such as relatively poor occurs.

Moreover, the contact arm A21 of conducting terminal A extends relative side arm A2 for the bending of terminal body A1 two side places, bend and extend into type by side arm A2 multistage again, the contact arm A21 of this kind continous way punching press bending forming will improve Design of Dies, degree of difficulty in the manufacturing, and the spacing d2 between each conducting terminal A behind the punching press bending forming broadens relatively, also will produce too much waste material area and cause the waste of material and cost, spacing in the middle of the two contact arm A21 of conducting terminal A institute punching press bending forming is difficult for keeping stable in addition, and after the crimp groove A31 on the connecting portion A3 is pressed into wire rod, also easily produce variation because of the connecting portion A3 related spacing of its two contact arm A21 that causes that is squeezed, just can cause the quantitative change of integral, flexible chucking power little, and then affect structural stability and electrical contact effect, redesign effectively and solved and remain to be engaged in this journey dealer.

The utility model content

So, the creator is because problem and the shortcoming that existing electric connector uses, be to collect related data via in many ways assessment and consideration, and utilize for many years research and development experience of engaging in the industry constantly to study and revise, begin to design the novel birth of this kind electric connector and terminal group thereof.
