For achieving the above object, novel electric connector described in the utility model, it comprises insulating body, shell and is contained in the interior terminal of insulating body, insulating body is the structure that lies low, front end is provided with interface and can inserts and electrically connect with terminal plug-in unit for outside, the holding tank of two outside indents about insulating body, holding tank extends setting backwards by the front end of insulating body, and goes out a draw-in groove in the interior concave end of holding tank; Shell is constructed by sheet metal forming, be " door " font, shell is placed in the place ahead of insulating body, construct one thus for the outside passage that connects that plug-in unit is inserted, linking arm is drawn towards the insulating body direction respectively in the left and right sides of shell, the corresponding respectively holding tank that is contained on the insulating body of two linking arms, and in the external part of linking arm to convexing with the elasticity stop portion, stop portion snaps in the draw-in groove; But the compressing tablet of a pressure holding outside to plug-in unit stretched out towards the insulating body direction in the upper end at shell.
The middle part of two lower hems is configured with the elastic clip of roof pressure inwardly respectively about described shell.
The position that described linking arm is connected with shell is configured with the oblique portion of invagination.
The lower bottom part of described insulating body is provided with several guide pillars, wherein has at least a guide pillar to have the face that scabbles of directivity.
Described stop portion is directly constructed in the linking arm punching press.
Be compared with the prior art, the utility model links together insulating body and shell by resulting structure, promptly is contained in the holding tank of insulating body by the linking arm on the outer casing back, and is snapped in by stop portion in the draw-in groove of insulating body, thereby shell and insulating body are connected to an integral body, realize location between the two, be installed on the circuit board accurate positioning together, spacing control is proper, the quality height of assembling, the use of pegging graft is smooth and easy, and practicality is good.
Another advantage of the utility model is that the shell upper end is configured with compressing tablet and the left and right sides is configured with elastic clip, realizes multi-faceted clamping outside thus to plug-in unit, strengthens the steadiness that electrically connects, and guarantees signal of telecommunication transmission, and practicality is good.
The utility model advantage again is that the lower bottom part of insulating body is provided with several guide pillars, is easily installed on the circuit board, and has at least a guide pillar to have the face that scabbles of directivity, prevents misloading, improves the speed and the efficient of installing.
Description of drawings:
Accompanying drawing 1 is a perspective view of the present utility model;
Accompanying drawing 2 is a schematic side view of the present utility model;
Accompanying drawing 3 is an insulating body structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See shown in the accompanying drawing 1～3, novel electric connector described in the utility model, mainly comprise insulating body 1, shell 2 and be contained in terminal 3 in the insulating body 1, insulating body 1 is the structure that lies low, front end is provided with interface and can inserts and electrically connect with terminal 3 plug-in unit for outside, the holding tank 11 of two outside indents about insulating body 1, and holding tank 11 extends setting backwards by the front end of insulating body 1, be L shaped, go out a draw-in groove 12 at the interior concave end of holding tank 11.Shell 2 is constructed by sheet metal forming, be " door " font, shell 2 is placed in the place ahead of insulating body 1, construct one thus for the outside passage that connects that plug-in unit is inserted, the corresponding respectively holding tank 11 that is contained on the insulating body 1 of linking arm 21, two linking arms 21 is drawn towards insulating body 1 direction respectively in the left and right sides of shell 2, and in the external part of linking arm 21 to convexing with elasticity stop portion 22, stop portion 22 snaps in the draw-in groove 12, and limit shell 2 withdraws from.Holding tank 11 is L shaped, and the shape of linking arm 21, big or small corresponding with holding tank 11, and 211 invaginations of the lower hem on the linking arm 21, increase bonding strength, make connection more firm.But the compressing tablet 23 of a pressure holding outside to plug-in unit stretched out towards insulating body 1 direction in the upper end at shell 2, insert for outside corresponding portion to plug-in unit just in gap on compressing tablet 23 and the insulating body 1 between the end face, and pressing plate 23 has the pressure that presses down to act in the corresponding portion to plug-in unit, the firm connection.The middle part of two lower hems is configured with the elastic clip 24 of roof pressure inwardly respectively about shell 2, the relative clampings of left and right sides elastic clip 24 insert to plug-in unit, limit left and right displacement thus to plug-in unit, realize that multi-faceted clamping limits plug-in unit, strengthen the steadiness that electrically connects, guarantee signal of telecommunication transmission, practicality is good.
