Description

Electric connector

The utility model is relevant a kind of electric connector, refers to a kind of socket connector that the conducting terminal on the needle-like terminal that even positive force acts on the banjo connector can be provided that has especially.

As shown in Figure 4, United States Patent (USP) the 5th, 437 has disclosed a kind of electric connector with several terminals 80 No. 567.Each terminal 80 comprises a pair of the first side wall 84 and a pair of second sidewall 84 ', and each sidewall 84,84 ' is provided with inwardly outstanding projection 86.Different with second sidewall 84 ', the first side wall 84 is provided with one and links to each other with its end section one and to relative second sidewall, 84 ' the vertically extending bottom 88.The free end 88a of this bottom 88 cooperates with second sidewall 84 ' and is formed with transverse opening 87, and this transverse opening 87 is roughly near second sidewall 84 '.Because two sidewalls 84,84 ' structure difference, therefore, two sidewalls 84,84 ' will produce unequal contact force on butt joint terminal 90 when butt joint terminal 90 inserts these terminals 80.

In view of this, need a kind of electric connector of design, to overcome the shortcoming of prior art with the conducting terminal on the opposite flank that the butt joint terminal that even positive force acts on insertion can be provided.

The purpose of this utility model is to provide a kind of electric connector that can produce the conducting terminal of even positive force on the opposite flank of inserting the butt joint terminal that has.

For achieving the above object, the utility model adopts following technical scheme: electric connector comprises that one has the insulating body of several accepting grooves and is housed in the interior terminal of corresponding accepting groove.Each terminal comprises holding parts, afterbody that is fixed in the accepting groove and the docking section that is positioned at the holding parts front end.The docking section comprises the elastic portion that the head that is positioned at its free terminal, a pair of and head and holding parts are separated by first and second slit that is parallel to each other respectively again and makes head, elastic portion be connected to base plate on the holding parts, has first cannelure on this base plate, two elastic portion is separated from each other by second cannelure relative with first cannelure and that be connected with aforementioned first and second slit, and first and second cannelure is positioned on the plane of symmetry of terminal center.So these elastic portion are to be with respect to the center plane of symmetry to be symmetrical arranged.

Electric connector with above-mentioned feature, wherein the medial surface of each elastic portion is provided with a pair of projection that is balanced configuration corresponding to the center plane of symmetry.When the butt joint terminal was plugged on it, symmetrically arranged elastic portion produced the distortion that equates, thereby can produce uniform positive force on the butt joint terminal that is inserted.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Fig. 2 is the stereogram of looking at the bottom of the electric connector terminal shown in Figure 1.

Fig. 3 is that Fig. 2 group is gone into to dock behind the terminal cutaway view along A-A line direction.

Fig. 4 is the cutaway view of existing bonder terminal.

See also Fig. 1, the utility model electric connector 1 comprises the insulating body 10 that is provided with several accepting grooves 12 and is contained in several terminals 20 in the corresponding accepting groove 12.

Insulating body 10 comprises front surface 101 and rear surface on the other side 103, the terminal containing slot 12 that is row's distribution up and down extends to rear surface 103 for the usefulness of inserting terminal 20 by front surface 101, between upper and lower row's terminal containing slot 12, be extended with microscler spacer body 125 and be separated from each other to guarantee terminal 20, along the lengthwise of each accepting groove 12 to being extended with a pair of projection 121 (only indicating among the figure).A pair of raceway groove 122 is arranged on the side of isolation part 13 respect to one another, and is connected with corresponding accepting groove 12.Each raceway groove 122 extends on the inner surface 123 respect to one another of projection 121 rear ends from rear surface 103.Further be provided with a pair of on the side of each isolation part 13 and the adjoining end difference 15 in its bottom surface.

Again please be simultaneously with reference to Fig. 2, each terminal 20 has included holding parts 21, afterbody 23 and docking section 24, and wherein docking section 24 and holding parts 21 are formed with accepting hole 201 for holding butt joint terminal 50 (as shown in Figure 3).Holding parts 21 is provided with a microscler main board portion 211, from the extended a pair of arm 213 of main board portion 211 lateral margins, is provided with rectangle neck 217 and is provided with alar part 219 in nearly main board portion 211 rear end at main board portion 211 front ends.Extend a pair of solid hammerlock 215 in the outside backward from neck 217 side back edge.

The docking section 24 of each terminal 20 is positioned at the front end of the neck 217 of holding parts 21, and separates with neck 217 by first slit 266 of " U " shape.The elastic portion 26, one that docking section 24 is provided with a pair of " L " shape is positioned at the rectangle head 25 of elastic portion 26 front ends and is parallel to the base plate 29 of the main board portion 211 of holding parts 21.In the middle of this base plate 29, be provided with first cannelure 291 that passes base plate 29.

Elastic portion 26 is separated by second slit 262 of one " U " shape with head 25, and this second slit 262 is parallel to first slit 266.First and second slit 266,262 all extends towards the cross-sectional direction of main board portion 211, and is interconnected by second cannelure 264, and this second cannelure 264 is positioned on the centre position of two elastic portion 26, and aligns in vertical direction with first cannelure 291.These elastic portion 26 are symmetrically distributed in relative both sides that comprise the plane of symmetry of the one the second cannelures 291,264.Each elastic portion 26 is equipped with several inwardly outstanding projectioies 261, thereby and gold-platedly on these projectioies 261 contact with butt joint terminal 50 reliably, these projectioies 261 are with respect to the plane of symmetry and are symmetrical arranged.

Afterbody 23 according to 21 groups of indivedual holding parts put on accepting groove 12 row or down ranking put and extend up or down from alar part 219.This afterbody 23 comprises a pars intermedia 231 that is provided with from alar part 219 bending of holding parts 21, fixed part 233 that is provided with from pars intermedia 231 continuities and the weld part 237 that is positioned at tail end.Also be provided with pair of ribs 235 on the fixed part 233 to strengthen afterbody 23.

During installation, terminal 20 is gone in the corresponding accepting groove 12 for 103 groups from the rear surface of the body 10 that insulate.After 20 groups of terminals are gone into, Gu hammerlock 215 is connected to projection 121 front ends, 213 on arm is fastened on projection 121 inboards, and alar part 219 is retained in the raceway groove 122 and connects with the inner surface 123 of corresponding insulating body 10, and the fixed part 233 of afterbody 23 is clamped between the end difference 15.

When 50 groups of butt joint terminals were gone into the projection 261 of aforementioned terminal 20, this projection 261 closely was connected to the side of butt joint terminal 50 and bears the contact force that the butt joint terminal applies.Under above-mentioned contact force effect, elastic portion 26 outwards produces certain distortion.Because elastic portion 26 symmetric arrangement and distortion equate, the contact force that 26 pairs of insertions of this elastic portion butt joint terminal 50 is wherein produced also equates.So butt joint terminal 50 can stably be organized and put in the accepting hole 201 of terminal 20 and guarantee that aforementioned protruding 261 coating is not damaged.The head 25 of elastic portion 26, docking section 24 and the neck 217 of holding parts 21 are separated by first slit 266, second slit 262 respectively, when when docking terminal 50 butt joint, outwards skew is upspring and is partly only limited to elastic portion 26, but not head 25 or neck 217, thereby the elasticity of raising elastic portion 26.
