Embodiment

Describe the preferred forms of the utility model electric connector in detail below with reference to diagram.

As shown in Figure 2, the utility model electric connector comprises housing 5, main body 6 and contact flat spring group 7, and contact flat spring group 7 is assembled in the main body 6, and housing 5 is sleeved on the outside of main body 6.

Shown in Fig. 2,3, main body 6 has surrounded a receiving space accommodating camera model 8 jointly by base plate and main body wall 64, and main body 6 is made by insulating material.Main body wall 64 is provided with the storage tank 67 of strip in the bottom, the opening of storage tank 67 is towards the inside of main body 6 accommodation space, and the strip through hole 66 that is provided with at interval on storage tank 67 and main body 6 base plates is communicated with the accepting groove that contact flat spring 71 is accommodated in formation.Main body wall 64 is made up of main body front, rear, left and right sidewall 641,642,643,644, the forward and backward sidewall of main body 641,642 both sides all are provided with shell fragment groove 61 respectively, this shell fragment groove 61 is empty from sidewall middle part to top side wall, and it is recessed that the following shell fragment groove 61 in middle part is shaped as concordant inboard, the outside, shell fragment 51 on housing 5 provides to enterolithic spatial accommodation, not only can reduce the required stress of shell fragment 51 distortion and can also make gap greatly needn't be arranged between camera model 8 and the main body 6.And for example shown in Figure 2, the left and right sidewall 643,644 of main body is provided with fixed gap 62 in the both sides of its bottom respectively, after the main body fixation spring tab 52 that is provided with housing 5 is fastened on the upper limb of this fixed gap 62, housing 5 just can not be more relatively main body 6 move up.Also be provided with guide slot 65 on the main body left side wall 643 simultaneously, cooperate directed portion 85 on the camera model 8 can guarantee that camera model 8 can the wrong plug direction, this guide slot 65 is preferably in the top and is set to outside inclined-plane, its degree of depth should be at least greater than half of the height of main body wall, can make assembling more smooth and easy like this, easier alignment when assembling is inserted.In addition, also being provided with two on the main body right side wall 644 misplaces in the location notch 63 of guide slot 65, the degree of depth of location notch 63 guide slot 65 only need be arranged half just can, with this 83 engagings of cooperation location division are set, and can guarantee just that with

guide slot

65,85 actings in conjunction of directed portion camera model is more stable under user mode.

Shown in Fig. 2-5, the utility model electric connector housing 5 is to strike out reservation shape earlier by sheet metal to form through bending for several times again, as shown in Figure 4, utilize plane convex-concave fastening structure to connect housing sidewall 54 two ends, housing sidewall 54 is divided into housing front, rear, left and right sidewall 541,542,543,544 again, and housing 5 comprises structures such as housing sidewall 54, latch part 53, shell fragment 51.Corresponding main body 6, housing 5 is before housing, rear wall 541,542 both sides are formed with several bar shaped shell fragments 51, the shell fragment side view bends inwards and forms reverse U shape, 51 at least two on this shell fragment is one group and is arranged on the sidewall, the both sides of each shell fragment 51 are the initial gap that all is provided with at housing 5 sidewall height and positions middle part, to guarantee that shell fragment 51 is not hindered, and the junction of shell fragment 51 and housing 5 is positioned at the top of housing sidewall 54, both junctions are fillet, shell fragment is towards main body accommodation space bottom, under the relaxed state, the angle of this shell fragment 51 and main body wall 54 is between 20 °-40 °, and these shell fragment 51 terminal bendings are for parallel with main body wall 54.Shell fragment 51 on the same group preferably is set to differing heights as shown in Figure 5, even the overall dimension of camera model 8 and lack of standardization can not influence itself and the engaging of the utility model electric connector yet, and can effectively prevent the rotation of camera model 8.

Shown in Fig. 2-5, housing 5 corresponding main bodys 6 inwardly have been stamped to form the main body fixation spring tab 52 that makes progress on the left and right sidewall 543,544 of housing, latch part 53 actings in conjunction that itself and housing sidewall 54 tops bend inwards just can interfix housing and main body, the main body fixation spring tab is inwardly to be stamped to form by housing sidewall, its opening direction upwards, that is: it is the acute angle opening with sidewall and makes progress.

As shown in Figure 2, the selected contact flat spring group 7 of the utility model electric connector, utilize the tie point and the circuit board welding at 711 rear portions, fastening end to realize the signal transmission, contact jaw 712 with deformation space by the contact chip of camera model 8 conflict bend after, produce the contact chip that recovery stress compresses camera model 8, thereby, make to the utlity model has more stable signal transmission effect.Because this shell fragment concrete structure is this area common structure, so do not repeat them here.

Shown in Fig. 2-5, during the utility model assembling, earlier each contact flat spring 71 with contact flat spring group 7 is assembled in the accepting groove of main body 6 correspondences, and the fastening end 711 of contact flat spring 71 snaps in the storage tank 67, and contact jaw 712 just passes in the accommodation space that through hole 66 has been fixed on main body 6.And housing 5 entangles main body 6 from top to bottom, and when the upper limb of the main body fixation spring tab 52 chucking fixed gap 62 of housing 5, after the top side wall of main body 6 was close to the latch part 53 of housing 5 simultaneously, housing 5 just had been fixed on main body 6.Then, shown in Fig. 3,4, camera model 8 from top to bottom inserts in the accommodation space of main body 6, because the alignment direction that directed portion 85 and guide slot 65 make camera model can deviation, four direction housing shell fragment 51 is fastened on the lower edge of holding section 81, location division 83 is fastened in the location notch 63, camera model 8 is combined in that fastening state and this electric connector are firm, the contact chip of camera model bottom each contact jaw 712 of being convenient to contact flat spring group 7 is firmly conflicted like this, thereby realizes that the camera model 8 and the signal of circuit transmit.

Electric connector of the present utility model can prevent effectively that camera model from rotating in using, and in addition, can also reduce the tolerance in electric connector and the camera model manufacture process in the main body accommodation space.

Though more than with most preferred embodiment the utility model has been described; but therefore do not limit scope of the present utility model; only otherwise break away from main idea of the present utility model, various distortion or change that those skilled in the art carry out all should belong to the utility model rights protection scope.
