Abstract
The utility model relates to an electric connector which comprises an insulting body and a plurality of conductive terminals, wherein both sides of the insulating body are arranged juxtaposedly and provided with two groups of terminal slots in which the conductive terminals are fixed; each conductive terminal comprises a first conductive part, a fixing part, an elastic part and a second conductive part which are connected in sequence, and the second conductive part of the conductive terminal is formed by being bent from the tail end of the elastic part towards the direction away from the fixing part firstly and then towards the direction close to the elastic part. The tail ends of the second conductive parts of the conductive terminals are bent towards the elastic parts which can be set to be longer when the volume of the electric connector is not increased, therefore, the conductive terminals have better elasticity and do not deform even being pressed for many times, and the electric connector can have stabler performance.
Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of electric connector that electrically connects first circuit board to second circuit board especially, and wherein, this electric connector is to be electrically conducted with face contact mode and second circuit board.
[background technology]
Electric connector is used very extensive at electronic applications, utilization is all arranged between assembly in electronic equipment and assembly, assembly and system, system and the system, is electrically connected and the signal transmission, is to constitute a necessary infrastructure component of holonomic system institute.
Existing a kind of electric connector that electrically connects first circuit board to second circuit board, the plurality of conductive terminals that it comprises insulating body and is contained in insulating body.After electric connector is welded in first circuit board, the welding foot of conducting terminal is welded on the first circuit board, when second circuit board and electric connector connect, second circuit board will be pushed conducting terminal, as the elastic portion elasticity of conducting terminal when not good, conducting terminal is subjected to second circuit board for a long time, be easy to generate distortion after the pushing repeatedly, thereby has influence on the performance of electric connector.
Based on described prior art, necessary existing electric connector is improved.
[utility model content]
Technical problem to be solved in the utility model: a kind of electric connector is provided, and the good springiness of its elastic portion is not easy to produce distortion, stable performance after being subjected to the compressing repeatedly, for a long time of circuit board.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of electric connector, it comprises insulating body and plurality of conductive terminals, the insulating body both sides are set side by side with two groups of terminal grooves, each conducting terminal is immobilizated in the terminal groove respectively, described conducting terminal comprises first junction, holding parts, elastic portion and second junction that links to each other successively, second junction of described conducting terminal is terminal earlier to the direction bending away from holding parts from elastic portion, is bent to form to the direction near elastic portion again.
Compared with prior art, second junction of conducting terminal is terminal earlier to the direction bending away from holding parts from elastic portion, be bent to form to direction again near elastic portion, under the situation that need not increase the electric connector volume, then elastic portion can be provided with longlyer, thereby can make conducting terminal have elasticity preferably, can not produce distortion even be subjected to repeatedly pushing also, like this, electric connector can have more stable performance.

[embodiment]
See also Fig. 1 to Fig. 3, electric connector 100, it can be used for electrically connecting first circuit board 4 to second circuit board 5, this electric connector 100 comprises insulating body 2 and plurality of conductive terminals 3, insulating body 2 has the installed surface 24 that matches with first circuit board 4, and the end face 23 relative with installed surface 24, these insulating body 2 both sides are set side by side with two groups of terminal grooves 21, and each conducting terminal 3 is immobilizated in respectively in the terminal groove 21 of insulating body 2.
See also Fig. 4 and Fig. 5, conducting terminal 3 comprises first junction 31, the holding parts 32 that link to each other successively, second junction 34 that is contained in the elastic portion 33 of terminal groove 21 and is used for being electrically connected with second circuit board 5 realizations, first junction 31 comprises and is in conplane weld zone 311 with installed surface 24 and is connected weld zone 311 and first bonding pad 312 of holding parts 32 that weld zone 311 is used to be soldered to first circuit board 4.Second junction 34 comprises contact zone 341 that protrudes in end face 23 and second bonding pad 342 that connects contact zone 341 and elastic portion 33, and second circuit board 5 can face contact district 341.Described holding parts 32 has the hangnail 321 of interfering fixing with insulating body 2.Described elastic portion 33 comprises the first continuous elastic arm 331 and second elastic arm 332, described first elastic arm 331 is arcuation, it links to each other with holding parts 32, described second elastic arm 332 is horizontal, it links to each other with second bonding pad 342, second bonding pad 342 and second elastic arm 332 are perpendicular, simple in structure, are easy to make.Second junction 34 of conducting terminal 3 is terminal earlier to the direction bending away from holding parts 32 from elastic portion 33, again to crooked and form near the direction of elastic portion 33, like this, under the situation that need not increase the electric connector volume, second elastic arm 332 of level can stretch out than a long segment distance, thereby can have preferable elasticity, though the conducting terminal 3 with this structure through second circuit boards 5 for a long time, pushing and also be difficult for producing distortion repeatedly.
The terminal groove 21 of insulating body 2 both sides is and is symmetrical arranged, and insulating body 2 both sides also can be provided with and each terminal groove 21 corresponding draw-in grooves 22, first bonding pad 312 of each conducting terminal 3 is fastened in respectively in the draw-in groove 22, can play the effect of better fixing conducting terminal 3.
