The assembling process that present embodiment is described in detail in detail is as follows:
As Fig. 2 and shown in Figure 6, this first row terminal 20, second row's terminal 30 need corresponding in advance produced by insert molding in first pedestal 11 and second pedestal 12, the Plug Division 211 of this first row terminal 20 is flush-mounted in the lower end pilot trench 102, the weld part 212 of first row's terminal 20 is divided into outside two groups of left and right sides faces that extend laterally first pedestal 11 respectively, stretch out forward outside the front end face of second pedestal 12 Plug Division 311 of this second row terminal 30, and the weld part 312 of this second row terminal 30 stretches out outside the rear end face of second pedestal 12 backward.The assembling of present embodiment is very simple, roughly can finish in two steps:
The first step, as Fig. 2 and shown in Figure 6, use second pedestal 12 to insert from the open rearward end of the accommodation space 103 of first pedestal 11, in the process that second pedestal 12 inserts, first guide block 121 of this second pedestal 12 inserts along first guide groove 112 of first pedestal 11, and the effect of guiding has been played in the insertion of 112 pairs second pedestals 12 of this first guide groove.When 121 insertions of first guide block put in place, the front end face of this second pedestal 12 is butted on the end face of locating piece 111 of first pedestal 11, and fixed block 122 spiral-locks of this second pedestal 12 are in the holddown groove 113 of first pedestal 11, can prevent effectively that second pedestal, 12 relative first pedestals 11 from overturning forward, realized the strong bonded of first pedestal 11 and second pedestal 12, formed insulating body 10, the weld part 212 of this first row terminal 20 and the weld part 312 of second row's terminal 30 are around the protruding distribution in edge of insulating body 10.Simultaneously, Plug Division 311 correspondences of this second row terminal 30 are flush-mounted in the pilot trench 101 of upper end.As shown in Figure 3 and Figure 4, first pedestal 11 and second pedestal 12 for assembling.
In second step, as shown in Figure 3 and Figure 4, first pedestal 11 and second pedestal 12 that assembles inserted from the open rearward end of screening can 40 in the lump.In the process of inserting, second guide block 114 of this first pedestal 11 inserts along second guide groove 42 of screening can 40, when 114 insertions of second guide block put in place, the front end face of this first pedestal 11 is butted on the bending part 43 of screening can 40, simultaneously, cramp 41 spiral-locks of this screening can 40 are in the location notch 123 of second pedestal 12, by this, this screening can 40 firmly envelopes insulating body 10 and hyoplastron 13, assembles finish (as Fig. 1 and shown in Figure 5).
During use, as shown in Figure 8, only needing weld part 312 with the weld part 212 of first row's terminal 20 and second row's terminal 30 to be welded on the external circuit board gets final product, because the weld part 212 of this first row terminal 20 and the weld part 312 of second row's terminal 30 all expose outside the insulating body 10, can easily the weld part 212 of first row's terminal 20 and the weld part 312 of second row's terminal 30 be welded on the circuit board 50, and make repair welding and sealing-off all easy in the extreme.
Design focal point of the present utility model is:
One, be divided into two groups of left and right sides faces that also extend laterally insulating body respectively by weld part with this first row terminal, the weld part of second row's terminal is stretched out the rear end face of insulating body, make each terminal weld part distribute around the periphery of insulating body, compare with the distribution mode of weld part of each terminal of tradition, the distribution mode of the terminal weld part of the utility model is more reasonable, all weld parts all are revealed in outside the insulating body, can be easily the weld part of each terminal be carried out repair welding or sealing-off, thereby help improving the quality and the efficient of product welded and installed, reduce the product fraction defective, thereby also reduced production cost.
Two, by arranging the terminal produced by insert molding in first pedestal with first, arrange the terminal produced by insert molding in second pedestal with second, that has removed tradition from is plugged in each terminal trouble in the insulating body one by one, makes that the assembling of product is easier, helps improving the packaging efficiency of product.
Three, by utilizing first guide block to cooperate plug-in mounting with first guide groove, and utilize fixed block to cooperate spiral-lock with holddown groove, make the pedestal of winning be installed in the accommodation space of second pedestal and can not overturn forward, improved the steadiness that first pedestal and second pedestal are assembled greatly.
Four, the cramp spiral-lock by utilizing screening can makes screening can firm with combining of insulating body, simple in structure in the location notch of second pedestal, and the assembling of screening can is also very convenient.
The above, it only is preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
