Description

Socket connector

The relevant a kind of socket connector of the utility model, refer to especially a kind of be used in personal digital assistant (Personal Digital Assistant, PDA) in, can insert in it to realize the socket connector of voice signal transmission for the voice plug.

In recent years, high speed development along with various miniature electronic products such as technology such as PDA(Personal Digital Assistant), mobile phone and hand-held computer, the socket connector especially application of voice socket connector on these miniature electronic devices day by day increases, the voice socket connector is arranged on the circuit board, is used for and docks the voice plug and be connected to form voice pathway.Relevant existing design please refer to United States Patent (USP) the 5th, 022, No. 872 cases, existing structure as shown in Figure 7, socket connector is provided with insulating body 5, the first terminal 6, second terminal 7 and the 3rd terminal 8, wherein the first terminal 6 is provided with a square shape frame portion 64, extend by frame portion 64 1 sides and to use the contact arm 65 that engages with the voice plug, opposite side then extends inserting foot 66, the structure of second terminal 7 is identical with the first terminal 6, and the 3rd terminal 8 is provided with two parallel retaining sheets 87, extend two slightly parallel contact chips 88 to a side in the middle of the retaining sheet 87, this contact chip 88 provides the effect of the elasticity arm of force, forms a clamp area 89 therebetween to be used in clamping butt joint voice plug, and above-mentioned square shape frame portion 64 and retaining sheet 87 all be used in insulating body 100 on groove 109,109 ' match, with the aforementioned terminal of fixing.

But, the 3rd terminal 8 is because the elasticity arm of force of contact chip 88 is shorter, fairness limit seldom, thereby when butt joint voice plug inserts, can not provide enough forward clamping contact forces, and in the frequent process of pegging graft of butt joint voice plug, because of the elasticity of the terminal elasticity arm of force relatively poor, might be urged and plastic deformation takes place, can't be returned to the state before butt joint voice plug does not insert, and transmission bring adverse influence to voice signal.

The utility model purpose is to provide a kind of socket connector, it is provided with can provide enough elastic arms of flexible degree, thus can overcome elastic arm elasticity in the prior art not good, easily plastic deformation takes place and the defective of state can't be returned to banjo and do not insert the time in use.

The utility model purpose is achieved in that socket connector comprises insulating body and plurality of conductive terminals at least, and wherein insulating body is provided with at least one spliced eye for corresponding plug insertion, is provided with several terminal containing slots in its two sides; Plurality of conductive terminals is located in the aforementioned terminal containing slot, it comprises a flexible terminal at least, this flexible terminal comprises main part, elastic arm and contact site at least, wherein autonomous body one lateral buckling of flexible terminal has a junction, from connecting portion to away from main part one skew back to bending and circuitous extended to form one with the not coplanar elastic arm of connecting portion, the elastic arm end is extended with a contact site to the side near main part, electrically to contact with other terminal.

Corresponding above-mentioned terminal structure, in the time of in docking voice plug insertion socket connector, the contact site of flexible terminal is docked voice plug thrusting action, because elastic arm can provide enough flexible degree, plastic deformation can not take place when plug inserts.

Compared with prior art, advantage of the present utility model is: the elastic arm of socket connector flexible terminal is longer, fairness limit is bigger, enough amount of deflection and deflections can be provided, can guarantee that elastic arm plastic deformation can not take place, thus the phenomenon of the state when avoiding occurring to be returned to butt joint voice plug and not inserting.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 5 is the vertical view of socket connector shown in Figure 1.

Fig. 6 is the right side view of socket connector shown in Figure 1.

Fig. 7 is the three-dimensional exploded view of existing socket connector.

Please refer to shown in Fig. 1,2, the utility model socket connector comprises insulating body 1, fixed terminal 2 and flexible terminal 3.Wherein insulating body 1 is a lengthwise square body, on its front surface 10, convex with cylindrical shape docking section 100, and in this docking section 100, be provided with the spliced eye 102 that is through to insulating body 1 inside and insert wherein for a voice plug (not icon), and realize the purpose of signal transmission.Be respectively equipped with several terminal containing slots that slightly is T-shape 120,140 on the relative two sides 12,14 of insulating body 1, be used for accommodating respectively fixed terminal 2 and flexible terminal 3.Surperficial thereon 11 both sides of insulating body 1 are provided with several bearings 16, and this bearing 16 is pressed against on the circuit board (not icon), thereby socket connector is fixed on the circuit board.

Please refer to shown in Figure 3, fixed terminal 2 is that integrated punching forms, its autonomous body 20 tops form a contact site 21 to a lateral buckling, to connect with flexible terminal 3, there is a horizontal welding foot 22 autonomous position, body 20 upper middle to the opposite side punching out, and with the surface adhering technology (Surface MountedTechnology SMT) is welded on the circuit board.Wherein the position of this contact site 21 is higher than the height of leg portion 22, and leg portion 22 is on the different planes with the contact site 21 of fixed terminal 2.

Please refer to shown in Figure 4, flexible terminal 3 also is that integrated punching forms, it is provided with main part 30 and leg portion 32 with fixed terminal 2 same structures, autonomous body 30 is extended with a junction 34 a little more than leg portion 32 positions to horizontal direction at leg portion 32 opposite sides relatively, connecting portion 34 to away from a skew back of main part 30 to bending and the circuitous elastic arm 35 that extended to form, elastic arm 35 ends are to having a contact site 36 near a side horizontal-extending of main part 30, are used for contacting with the contact site 21 of fixed terminal 2 and realize electrically connecting.This elastic arm 35 and contact site 36 be through repeatedly oblique extension setting, finally form one with the not coplanar square shape of connecting portion 34.When butt joint voice plug does not insert in the socket connector, the contact site 36 of flexible terminal 3 is resisted against the contact site 21 of fixed terminal 2, when butt joint voice plug inserts in it, the contact site 36 of flexible terminal 3 is subjected to docking the thrusting action of voice plug and is separated with the contact site 21 of fixed terminal 2, because this elastic arm 35 can provide enough amount of deflection and deflections, can guarantee that elastic arm 35 plastic deformation can not take place, and the phenomenon of the state butt joint voice plug can not occur being returned to and do not insert the time.

Please in conjunction with shown in reference Fig. 5,6, the main part 20 of fixed terminal 2 is plugged in the terminal containing slot 120 of socket connector insulating body 1, and the main part 30 of flexible terminal 3 is plugged in the terminal containing slot 140 of insulating body 1, and guarantee fixed terminal 2 leg portion 22, flexible terminal 3 leg portion 32 places at grade, thereby constitute the complete structure of socket connector.
