As shown in Figure 1, electrical connection device 1 provided by the utility model comprises insulating body 2, several terminals 3 and shell 4.Next, we explain being constructed as follows of electric connector 1 with reference to Fig. 2.

Insulating body 2 is single plastic cement molded components, comprises front surface 21, rear surface 22, left-hand face 23, right lateral surface 24, upper surface 25 and lower surface 26 haply.Upper surface 25 is provided with holding parts 251, and holding parts 251 is provided with several parallel slots 2510, the end face that parallel slot 2510 runs through holding parts 251 form hole 2510 '.The and arranged on left and right sides of lower surface 26 then is respectively equipped with flange 261, and its periphery is provided with several hemispherical 263, as shown in Figure 6.Vertical zone line of front surface 21 and rear surface 22 is respectively equipped with guidance part 215,225 from top to bottom and (is mutually symmetrical, 225 are not shown among the figure) and retainer 217,227, the former is the depression of inclination, and the latter then is smooth depression, between the two every one section suitable distance.In addition, forward and backward, left side and right lateral surface are common forms a space 20 that holds terminal 3.

Each conductive metal terminals 3 all comprises contact-segment 31, interferes section 33 and inserting section 35.Interference section 33 1 ends of terminal 3 connect contact-segment 31, and the other end then connects inserting section 35.Fig. 4,5 at length shows the structure of terminal interference section 33, wherein interferes end both sides that are connected with inserting section 35 of section 33 to be respectively equipped with arc notch 330.We will illustrate the feature and benefit of breach subsequently.

Shell 4 coats work insulating body 2, comprises front surface 41, rear surface 42, left-hand face 43 and right lateral surface 44 haply.The front surface 41 of shell and rear surface 42 are respectively equipped with one first installation component 40a, and electric connector 1 can be installed in the perforation on the circuit board P thus.In the present embodiment, the first installation component 40a is for generally haveing the knack of the plate lock known to this operator.Yet for avoiding mispluging, these two installation component 40a are configured on the same straight line.In other words, these two elements form " fool proof " (a fool proof) measure.In addition, be installed in stability on the circuit board P for increasing electric connector, we can set up one second installation component 40b at front surface 41 or rear surface 42.This one second installation component can be so-called plate lock, also can be a simple U-shaped element, as shown in Figure 1.But, rear surface 42 is shell 4 fourth of the twelve Earthly Branches He Chu, and available space is very limited, so preferably the second above-mentioned installation component 40b is configured on the front surface 41.For making this electric connector 1 connect securely and fit over waiting to connect the pin connector (not shown) of joining, the front surface 41 of shell is provided with the second folder pincers member 413 of two first inverted U-shaped folder pincers members 411 and a U-shaped.The first and second folder pincers members 411,413 are all direct spring leaf in shell 4 drawings.In addition, the appropriate location of front surface 41 and rear surface 42 is respectively equipped with the depression 415,425 (being mutually symmetrical) corresponding to the inclination of the guidance part 215,225 of above-mentioned insulating body.
