Charging needs to adopt charging terminal, not comprising shell fragment in traditional charging terminal, only is that working of plastics is fixed on the pcb board, and shell fragment is fixed on pcb board as another parts, fixing respectively, bother very much at assembling process like this, because the quantity of metal clips is very many, increased labour intensity to operating personnel simultaneously, the assembling of multiple operation, mistake occurs easily, reduced simultaneously operating efficiency, improved production cost.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of fixing locating terminal of multi-point welding that adopts is provided, this locating terminal simple in structure, charging terminal adopts the integral type design, and the metal clips position is accurate; Can directly weld by SMT, avoided artificial welding error; Adopt direct SMT welding, reduced follow-up artificial welding sequence, reduced workman's labour intensity; The SMT welding guarantees product yield and production efficiency, utilizes the contact groove, so that the position of shell fragment is more accurate, so that the efficient of welding increases.
Purpose of the present invention is achieved through the following technical solutions: adopt the fixing locating terminal of multi-point welding, comprise charging terminal and pcb board, described charging terminal is fixed on the pcb board, is provided with several contact grooves on the described pcb board.
Described charging terminal comprises shell fragment and working of plastics, and described shell fragment is arranged on the working of plastics, and described shell fragment and working of plastics all are fixed on the pcb board.
It is inner that described shell fragment is welded on corresponding contact groove.Shell fragment welds, and has increased the firmness of shell fragment and pcb board.
Be provided with boss on the described working of plastics, be provided with groove on the described pcb board, the top of described boss contacts with the bottom of groove.
The size of described boss and the size of groove are complementary.Adopt the size of coupling, so that the installation of working of plastics and pcb board is more stable, in use can not come off.
The quantity of described boss and groove is four, and described boss is symmetricly set on the both sides of shell fragment.The groove of both sides cooperates with boss, can be so that locating terminal is more stable.
In sum, the invention has the beneficial effects as follows: this locating terminal simple in structure, charging terminal adopt the integral type design, and the metal clips position is accurate; Can directly weld by SMT, avoided artificial welding error; Adopt direct SMT welding, reduced follow-up artificial welding sequence, reduced workman's labour intensity; The SMT welding guarantees product yield and production efficiency, utilizes the contact groove, so that the position of shell fragment is more accurate, so that the efficient of welding increases.
