Description
Technical field:
The utility model relates to the network filter technical field, relates in particular to the network filter sheet that is provided with resin sealing bar.
Background technology:
Along with the development of computer technology and mechanics of communication, network filter has been widely used in Internet, and general lattice network device is provided with network filter.
At present, the production procedure of network filter is generally, network filter sheet is carried out welding lead after, gluing is packaged into the semi-finished product network filter, double finished product network filter done product test again.Welding between the inner pin of lead-in wire and end pin is to adopt the welding procedure of Reflow Soldering to realize, this welding procedure is allocated scolder on the pad in advance by refuse, realize between end pin and the pad machinery be electrically connected.The scolder that Reflow Soldering is used is a solder containing lead, therefore in welding process, solder containing lead is back to the outer end pin of end pin easily, and the outer end pin has adhered to lead as harmful matter and contaminated, make the network filter product can not satisfy unleaded environmental requirement, improved the fraction defective of product.In addition, because existing network filter sheet, its tablet framework and end pin are integrated, product test must just can be carried out half-finished the time producing, if test can't be passed through, semi-finished product just become defective item, thereby become the waste product material, not only reduce operating efficiency, also increased production cost.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, a kind of network filter sheet that is provided with resin sealing bar is provided, and this network filter sheet can effectively avoid the outer end pin contaminated, improves yield of products, and can also increase work efficiency, reduce production costs.
For achieving the above object, the utility model is by the following technical solutions:
Be provided with the network filter sheet of resin sealing bar, it comprises the tablet framework, left and right sides punch forming in the tablet framework has the end pin, the two ends of end pin are respectively inner pin and outer end pin, described in the tablet framework between the inner pin of end pin in left side and the outer end pin injection mo(u)lding resin sealing bar in left side is arranged, injection mo(u)lding has right side resin sealing bar between the inner pin of the end pin on right side and the outer end pin in the tablet framework.
The outer end pin and the tablet framework of described end pin are connected as a single entity, and the inner pin of end pin is a curved end.
The quantity of described end pin is 16, and the end pin quantity that is positioned at the tablet framework left and right sides is 8.
The punch forming of described tablet framework has fabrication hole.
This network filter sheet is arranged side by side by a plurality of tablet frameworks and is one.
The utility model beneficial effect is:
The network filter sheet that is provided with resin sealing bar described in the utility model, injection mo(u)lding has left side resin sealing bar between the inner pin of its end pin in left side in the tablet framework and the outer end pin, and injection mo(u)lding has right side resin sealing bar between the inner pin of the end pin on right side and the outer end pin in the tablet framework; Adopt the network filter sheet of said structure, left side resin sealing bar and right side resin sealing bar have formed the separate seat between inner pin and the outer end pin, in welding process, solder containing lead is by left side resin sealing bar and the obstruct of right side resin sealing bar and can not be back to the outer end pin, therefore can effectively avoid the outer end pin contaminated, improve yield of products; In addition, because left side resin sealing bar and right side resin sealing bar have formed the separate seat between inner pin and the outer end pin, before producing the network filter semi-finished product, network filter sheet is carried out can carrying out product test behind the welding lead, after the test passes, gluing is packaged into the network filter semi-finished product again, avoids the waste of material effectively, both increased work efficiency, reduced production costs again.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment one, as shown in Figure 1, be provided with the network filter sheet of resin sealing bar, it comprises tablet framework 1, left and right sides punch forming in the tablet framework 1 has end pin 2, the two ends of end pin 2 are respectively inner pin 22 and outer end pin 21, described resin sealing bar 3 on the left of between the inner pin 22 of end pin 2 in left side and the outer end pin 21 there be injection mo(u)lding tablet framework 1 in, and injection mo(u)lding has right side resin sealing bar 4 between the inner pin 22 of the end pin 2 on right side and the outer end pin 21 in tablet framework 1.In the present embodiment one, network filter sheet is made up of single tablet framework 1, wherein, the outer end pin 21 and the tablet framework 1 of described end pin 2 are connected as a single entity, the inner pin 22 of end pin 2 is a curved end, and inner pin 22 is used for and wire bonds, and outer end pin 21 is then as the pin of network filter finished product.
Adopt the network filter sheet of said structure, the separate seat that left side resin sealing bar 3 and right side resin sealing bar 4 have formed between inner pin 22 and the outer end pin 21, in welding process, solder containing lead is by left side resin sealing bar 3 and 4 obstructs of right side resin sealing bar and can not be back to outer end pin 21, therefore can effectively avoid outer end pin 21 contaminated, improve yield of products; In addition, because the separate seat that left side resin sealing bar 3 and right side resin sealing bar 4 have formed between inner pin 22 and the outer end pin 21, before producing the network filter semi-finished product, network filter sheet is carried out can carrying out product test behind the welding lead, after the test passes, gluing is packaged into the network filter semi-finished product again, avoids the waste of material effectively, both improved operating efficiency, reduced production costs again.
