Description

Patch with welding pin connector

Technical Field

The utility model relates to a connector especially relates to paster area welding pin connector.

Background

With the continuous and high-speed development of internet information technology, hardware equipment adapted to the internet is also continuously updated and iterated. Many electronic products are being improved, so that the products are lighter, thinner and smaller, and the assembly is more convenient.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, a patch ribbon bonding pin connector which is thinner than the traditional connector in the whole thickness is specially manufactured.

In order to achieve the above object, the present invention provides the following solutions: paster area welding pin connector, including base main part, inner core and terminal, base main part bottom is equipped with the opening, and the opening both sides are equipped with the slot, and the inner core cooperation of pegging graft is at the opening part of base main part bottom, and inner core formula injection moulding as an organic whole, terminal include kink and paster portion, and paster portion fixes in the inner core through the mode of moulding plastics.

Furthermore, the upper surface of the inner core is provided with a front long hole for positioning the terminal by an injection mold in the injection molding process, and the lower surface of the inner core is provided with a back positioning hole for positioning the terminal by the injection mold in the injection molding process.

Further, the bottom of the base main body is also provided with a patch welding leg used for being connected with the PCB.

Further, the base main body is of an all-plastic structure.

Furthermore, the bottom of the base main body is provided with two slotted holes for mounting the patch welding feet.

The utility model discloses an useful part lies in:

1. the utility model discloses the structure is fixed some terminals at terminal bending part and paster position in the plastic inner core through the mode of moulding plastics molding, and it is bad to have avoided terminal stress to produce the roughness that deformation leads to terminal paster position like this, and processing procedure simple process has improved the yield of product greatly, low in manufacturing cost.

2. The plastic inner core is provided with a plurality of reverse side positioning holes on the front and the reverse sides, and the injection mold compresses the terminal by means of the front side long hole and the reverse side positioning hole in the injection molding process, so that the deformation stress of the terminal generated under the pressure action in the injection molding process is avoided.

3. Adopt the mode of leg, respectively set up a paster leg in base both sides bottom, fix the product through leg and customer PCB welded mode, shielding shell part has been cancelled to this structure, has solved the fixed firm problem of product simultaneously.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Patch area welding pin connector, including base main part 1, inner core 3 and terminal 2, base main part bottom is equipped with the opening, and the opening both sides are equipped with the slot, and the inner core cooperation of pegging graft is at the opening part of base main part bottom, and inner core formula injection moulding as an organic whole, terminal include kink 22 and paster portion 21, and paster portion fixes in the inner core through the mode of moulding plastics. The inner core upper surface is equipped with the positive slot hole that the injection mould advances line location to the terminal at the in-process of moulding plastics, and the inner core lower surface is equipped with the reverse side locating hole that the injection mould advances line location to the terminal at the in-process of moulding plastics.

The traditional SMT paster RJ network connector has the advantages that the requirements on flatness are difficult to say due to the stress problem of terminal bending forming usually, the processing procedure reject ratio is high, and the manufacturing cost is high no matter a PIN inserting structure or an injection molding structure. The terminal bending part and a part of the terminal of the patch part are fixed in the plastic inner core in an injection molding mode, so that the poor flatness of the patch part of the terminal caused by the deformation of the terminal stress can be avoided.

In order to fix the terminal in the plastic inner core in an injection molding mode, the terminal can be accurately positioned in the mold, therefore, the front long hole 32 is formed in the upper surface of the plastic inner core, the back positioning hole 31 is formed in the back surface of the plastic inner core, and the terminal is pressed by the upper mold workpiece and the lower mold workpiece, so that the terminal is prevented from generating deformation stress under the action of pressure in the injection molding process.

The bottom of the base main body is also provided with a patch welding leg 4 used for being connected with a PCB. The base main body is of an all-plastic structure. The bottom of the base main body is provided with two slotted holes 11 for mounting patch welding feet. Traditional paster product is for guaranteeing with customer PCB welding fastness, adopts shielding shell iron foot and PCB paster welded fastening mode to fix the product usually, and this kind of mode needs to increase a shielding shell, does not need in ordinary low-speed network, and a more shielding shell product cost is very high. Adopt the leg mode, respectively set up a paster leg in base body both sides bottom, fix the product through leg and customer PCB welding mode, shielding case part has been cancelled to this structure, has solved the fixed firm problem of paster product simultaneously, and the product quality obtains the guarantee, realizes low in manufacturing cost simultaneously, has fine market competition.

It is obvious to a person skilled in the art that the invention is not limited to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention, and that the embodiments are therefore to be considered in all respects as exemplary and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
