Language concrete meaning in this utility model.
As long as additionally, technical characteristic involved in this utility model difference embodiment disclosed below is each other
The conflict of not constituting just can be combined with each other.
Embodiment 1
The present embodiment provides a kind of backstep welding connecting connector, and with reference to Fig. 1, it mainly includes needle stand 1 and Pin pin 2, Pin pin 2
Can be fixedly installed by means of needle stand 1, after Pin pin 2 is installed on needle stand 1, then assemblies that both are constituted are installed to
On Pcb plate.The stitch 21 of Pcb plate correspondence needle stand 1 and Pin pin 2 is respectively arranged with installing port 42 and stitch hole 41, finally to pin
Circuit on foot 21 and Pcb welds, thus completes installation and the welding process of adapter.Pin pin 2 can be from Pcb plate
Obtain electric current or the signal of telecommunication, then pass through the female end 12 with needle stand 1 phase clamping.In existing adapter product, due to
Female 12 is typically and needle stand 1 carries out snap-fit engagement in the same side of Pcb plate, that is to say that the leg of female 12 and stitch 21 is positioned at
The both sides of Pcb plate, for the ease of the connection of female 12, then must be by needle stand 1 side of Pcb plate towards the opening one of casing for electric appliances
Side is arranged, and thus causes in maintenance process, if desired checks the problems such as leg is the most firm, it is necessary to after being removed by Pcb plate,
Leg can be seen.In the present embodiment, needle stand 1 is provided with the mounting groove 13 for connecting female end 12 at installing port 42,
Female end 12 is connected with mounting groove 13, so that stitch 21 and female end 12 are positioned at the same side of Pcb plate through installing port 42.Also
I.e., when mounted, needle stand 1 side can be arranged back to the opening side of casing for electric appliances, therefore maintenance process need not again
Pcb plate is removed, i.e. it can be seen that leg is the most firm, effectively solves existing product maintenance, technological deficiency difficult in maintenance.
The Second Problem that existing adapter exists is being: during welding, generally blocks needle stand 1 interface and described peace being used for
Fill mouth 42 is the protector of the not reproducible utilizations such as tinfoil, result in substantial amounts of wastage of material and adds production cost.
For solving this technical problem, with reference to Fig. 6-9, the protector in the present embodiment is protective cover 5, and described protective cover 5 can be with described
Pin pin 2 on needle stand 1 or described needle stand 1 forms location structure, so that described protective cover 5 can block described installing port 42 also
Keep fixing.As one preferred embodiment, protective cover 5 includes the base plate 51 for blocking described installing port 42, and sets
Put vertical section 201 interference engagement of a pair location division on described base plate 51, described location division and described Pin pin 2, thus
Described protective cover 5 and Pcb plate is made to keep being relatively fixed.Obviously the structure that can form interference engagement has a lot, in the present embodiment
Preferably, described location division includes two vertical plates 521 of opposing parallel setting, and the top of two vertical plates 521 forms phase
The most close projection；Corresponding described projection, the vertical section 201 of described Pin pin 2 forms recessed portion, when
After described protective cover 5 inserts described installing port 42, described projection snaps in the female part, thus forms interference engagement.
As it is shown in fig. 7, after Pin pin 2 and needle stand 1 are installed and fixed, the assembly that both combine formation is installed to Pcb
On plate, now protective cover 5 can be loaded by mounting groove 13, by location division and the Pin of the convex form on vertical plate 52
Groove on pin 2 forms interference engagement, thus keeps fixing.So in the welding process to stitch 21, the material such as soldering paste is not
Can enter in needle stand 1.And after stitch welding terminates, with reference to Fig. 8, staff only needs to exert a force down and presses described protective cover
5, described interference structure is destroyed, protective cover 5 can depart from Pcb plate and needle stand 1 automatically, very convenient to use.
It should be noted that protective cover 5 obviously can also be by means of the preformed hole etc. offered on needle stand 1 or Pcb plate
Needle stand 1 is protected by mode, but owing to the vertical section in Pin pin 2 is originally i.e. for connecting female end 12, therefore practical
For it is as the connection end of protective cover 5, it is not necessary to the link position on Pcb plate or needle stand 1 is separately provided, therefore has
Help reduce procedure of processing, cost-effective.
The set-up mode of needle stand 1 and Pin pin 2 in the present embodiment is described in detail below in conjunction with Fig. 1-Fig. 6:
With reference first to the schematic diagram of the adapter under the welding completion status shown in Fig. 1, Fig. 2 and Fig. 3, and Fig. 2 also shows
Going out, female end 12 is connected on needle stand 1.In order to make needle stand 1 to facilitate, and firm being connected on Pcb plate, in the present embodiment
Preferably offering the installing port 42 of rectangle on Pcb plate, two limits of corresponding installing port 42, the both sides, lower end of needle stand 1 form
First elastic back-off 111, described first elastic back-off 111 limit corresponding with installing port 42 shape after stretching into described installing port 42
Become back-off structure.
Structural representation with reference to the Pin pin 2 shown in Figure 10:
Pin pin 2 mainly includes three parts, the vertical section of the vertical spacing groove for being vertically inserted in needle stand 1
202, it is laterally embedded into the lateral part 201 in the cross spacing groove on needle stand 1, and can be through the stitch limit on needle stand 1
Position groove 101 stitch 21 through the stitch hole 41 on Pcb plate.
Referring again to the structural representation under the installment state of the Pin pin 2 shown in Fig. 4 and Fig. 5 and needle stand 1, the horizontal stroke of Pin pin 2
To part 201, vertical section 202 and stitch 21 respectively by the cross spacing groove on needle stand 1, vertical spacing groove and close
The stitch stopper slot 101 of described stitch 21 is limited, thus ensure that the firm and stable of Pin pin 2, does not allows after installation puts in place
Easily occur changing, to ensure that stitch 21 can be inserted in stitch hole 41 accurately, in order to follow-up welding job on position
Carry out.
In order to make vertical section 202 can further limit Pin pin vertical on degree of freedom, as shown in Figure 10, described
The end of the vertical section 201 of Pin pin 2 forms barb structure, and described vertical section 201 extend into described vertical spacing groove
After, described barb structure can form interference fit with described vertical spacing groove, so vertical after Pin pin 2 inserts and puts in place on
Just it is less likely to occur to loosen.
Additionally, with reference to Fig. 3, in order to make female end 12 and the connection of needle stand 1 stable and convenient, in the both sides molding of described female end 12
Having the second elastic back-off 121, the position of the corresponding described second elastic back-off 121 of the mounting groove 13 of described needle stand 1 forms and matches
The protuberance 131 closed, after described female end 12 stretches into described needle stand 1 through described installing port 42, the described second elastic back-off 121 with
Described protuberance 131 forms back-off structure.
And, preferably Pin pin 2 is copper particularly pyrite stamping parts.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.
For those of ordinary skill in the field, the change of other multi-form can also be made on the basis of the above description
Or variation.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out
Or among the protection domain that variation is still in this utility model creation.
