Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of patching terminal, is used for improving paster efficient and paster quality.
Below by specific embodiment the technical solution of the utility model is described in detail, sees also Fig. 1 to Fig. 4:
A kind of patching terminal comprises: head 1 and terminal axle 2, and head 1 and terminal axle 2 are fixed together, wherein, patching terminal cooperates with terminal hole on the pcb board by terminal axle 2, and the root of terminal axle 2 is provided with the avoiding hollow groove 21 of dodging burr, wherein, head 1 is flat.
It should be noted that, the concrete shape of the patching terminal in the present embodiment is not done restriction.For convenience, present embodiment is described as the rivet-like patching terminal as example take this patching terminal, sees also Fig. 1, Fig. 1 be this rivet-like terminal partly cut open front view.
Wherein, see also Fig. 1, head 1 and the terminal axle 2 of this patching terminal are fixed together, and wherein, head 1 and terminal axle 2 can be connected as a single entity, and can be rivet-like.
Wherein, the patching terminal in the present embodiment can mount it on assigned address of circuit substrate (PCB, Printed Circuit Board) by patch device.Concrete, in use, the lower plane of head 1 forms soldering with pad on the pcb board and is connected, simultaneously the terminal hole employing plug-in type shaft hole matching on terminal axle 2 and the pcb board.
Preferably, can cooperate smoothly with terminal hole on the pcb board in order to make terminal axle 2, and cooperate firmly, can be provided with the avoiding hollow groove 21 of dodging burr at terminal axle 2, specifically can consult Fig. 1.Because the terminal hole surface of pcb board may have some burrs to clear up fully, establishes avoiding hollow groove 21 at terminal axle 2, avoiding hollow groove 21 can be dodged the burr on the terminal hole, improves the paster quality.
It should be noted that, specifically the cross sectional shape of the avoiding hollow groove 21 of terminal axle 2 roots do not limited.For example, this avoiding hollow groove 21 can for the trapezoidal groove around terminal axle 2 roots one circle, also can be arc groove.
Preferably, when for the suction nozzle that makes patch device this patching terminal being picked up, can form vacuum with patching terminal fast, and patching terminal firmly is transported on the terminal hole of pcb board, head 1 can be made as flat.
Preferably, can establish lines 221 in the bottom 22 of terminal axle 2, the bottom that also is used for simultaneously improving this patching terminal is when mounting and the adhesive force of tin cream.
It should be noted that, the concrete shape of the lines 221 of the bottom 22 of terminal axle 2 is not limited.Optionally, as shown in Figure 3, Fig. 3 is the upward view of patching terminal in the present embodiment, the schematic diagram of the bottom 22 of terminal axle 2 namely, and lines 221 can be radial shallow line.For example, this lines 221 also can be the shape such as latticed.
Optionally, can be provided with on the surface of terminal axle 2 guiding gutter 23 for conducting tin material, guiding gutter 23 can make the part tin cream melt the bottom that flows to patching terminal when the mistake Reflow Soldering, forms tin welding spot in the bottom 22 of patching terminal, can make things convenient for the operations such as later welding lead.
