Embodiment
Please refer to shown in Fig. 1 to Fig. 5, the concrete structure that it has demonstrated the preferred embodiment of the utility model, includes plastic cement main body 10 and is plugged in the terminal group 20 in plastic cement main body 10.
Wherein, as shown in Figure 1, 2, this plastic cement main body 10 is rectangular structure, and the through two rows terminal groove 11,12 that is provided with in front and back in plastic cement main body 10, in being inserted into for terminal group 20.
As shown in Figure 2, described terminal group 20 has two rows, and the obverse and reverse of upper and lower row's terminal 21,22 is reverse each other.Wherein, upper row's terminal 21 has 15 conducting terminals, and lower row's terminal 22 also has 15 conducting terminals, and two rows terminal 21,22 is plugged in respectively in each self- corresponding terminal groove 11,12.
As in Figure 3-5, each conducting terminal of this upper and lower row's terminal 21,22 includes holding parts 23, contact site 24, the SMT pin 25 of one-body molded connection.
This holding parts 23 be by upper retaining sheet 231, lower retaining sheet 232 and one be connected between upper and lower retaining sheet 231,232 in retaining sheet 233 form, by upper retaining sheet 231, in retaining sheet 233 and lower retaining sheet 232 threes surround grafting chamber 234.Wherein, the rear end of this lower retaining sheet 232 and middle retaining sheet 233 all has extension bit 235, make retaining sheet 231 compare middle retaining sheet 233 and lower retaining sheet 232 short.On this, the outside of retaining sheet 231 has the first stuck point 236 of a plurality of overhead kick shapes, the outside of described lower retaining sheet 232 is individual the second stuck point 237 that has a plurality of overhead kick shapes also, this first stuck point 236 is identical with the second stuck point 237 structures, and be in alignment with each other symmetrically up and down, when this design can prevent that conventional conductive terminal from inserting, each stuck point position is different and cause the problem of SMT pin 25 off normals.Also have, in this, the upside of retaining sheet 233 rear end extension bit 235 is provided with the 3rd stuck point 238 of overhead kick shape, and this structure can keep the line balancing of conducting terminal.Moreover on this, the rear end one of retaining sheet 231 is extended grounding elastic part 26, can push against in the top of terminal groove 11 or 12, conducting terminal is plugged in after terminal groove, can cannot not push against looseningly.In addition, the extension design of these upper and lower retaining sheet 231,232 one end near contact site 24 faces 239 directly to form to extend to cushion, when this design can prevent that conducting terminal is pressed into plastic cement main body 10, buffering is faced directly and is caused not the problems such as SMT pin 25 coplane degrees are inadequate and linear bad.
This contact site 24 is comprised of the upper clip 241 arranging in opposite directions and lower clamping piece 242, this upper and lower intermediate plate the 241, the 242nd, faces 239 directly by the prolongation buffering of upper and lower retaining sheet 231,232 front ends and extends to form forward, the front end of this upper and lower intermediate plate 231,242 is to be hung in terminal groove 11,12, and there is bending 243 to form arc, thereby upper and lower intermediate plate 231,242 encloses the terminal interface 244 that formation can elasticity be magnified and dwindled together.
Described SMT pin 25 one are connected in the rear end of retaining sheet 232 under holding parts 23.Wherein, the SMT pin of upper row's terminal 21 and the link position between holding parts 23 are provided with bending position 251, the SMT pin of lower row's terminal 22 and the link position between holding parts 23 do not arrange bending position 251, the SMT pin 25 of upper and lower row's terminal 21,22 is all arranged in a row at grade, is convenient to carry out SMT welding.
Holding, as shown in Fig. 6-10, in the production process of described terminal group 20, is first to produce terminal material belt 30.During moulding, be on same a slice sheet metal once punch forming go out terminal material belt 31-34.In the present embodiment, because the volume of plastic cement main body 10 is little, the every row of terminal groove 11 or 12 has 15 more than, make the spacing between each conducting terminal small and dense, in same row's terminal material belt, be difficult to disposable 15 conducting terminals that stamp out, therefore the present embodiment is by being plugged in for twice in the same row's terminal groove 11 with the first terminal material strip 31 of 13 conducting terminals with the second terminal material belt 32 of 12 conducting terminals respectively, to complete plug-in mounting process.The installation of lower row's terminal groove 12 is also so, by the 3rd terminal material belt 33 and the 4th terminal material belt 34 twice plug-in mounting, is formed.
As shown in Fig. 9,10, the conducting terminal of every terminal material belt 30 is the one-body molded material strip 35 that is connected in all, between this material strip 35 and conducting terminal, be to be connected by a connecting piece 36, this brace 36 is specifically connected in the rear end of middle retaining sheet 233, link position at the two is carved with easily broken position 37, facilitates this brace 36 to be connected to the clear really rate of removing material strip 35 in order to improve.Also have, in brace 36, near one end of conducting terminal, be provided with the concave point 38 of stepping down, this design can prevent from when conducting terminal from inserting interfering with the catch 13 of plastic cement main body 10 rear ends, makes the terminal can disposable being pressed into place, and minimizing terminal assembly process, enhances productivity.In addition, in material strip 35, be provided with protection pin 39, avoid producing, packing rewinding and cause while electroplating rewinding SMT pin drag askew, miscue and flatten.
In sum, design focal point of the present utility model is, the first stuck point 236 on the holding parts of conducting terminal 23 and the second stuck point 237 are designed to laterally zygomorphic alignment structures, stress balance while making to install, prevent that when conducting terminal is pressed into plastic cement main body 10, buffering is faced directly inadequate and makes in the inadequate and linear bad problem of SMT pin flatness, the SMT pin of guaranteeing each conducting terminal is positioned at same level, guarantees the quality after SMT scolding tin.
In addition, the holding parts 23 of conducting terminal adds to grow and extends buffering and faces 239 directly, and when this design can prevent that conducting terminal is pressed into plastic cement main body 10, buffering is faced directly and caused not SMT pin flatness not and the problem such as linear bad.
Also have, terminal material belt 30 places are designed with and step down, when this design can prevent that conducting terminal from inserting with catch 13 interference of main body plastics, the conducting terminal of traditional handicraft need be done to be pressed into for twice just and can be pressed onto position, only need to press now once just can be pressed onto position, reduce the assembly process of conducting terminal, enhance productivity.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
