no. 1 example

[0029] The first embodiment is a waterproof wired component, which includes two leads and a chip welded between the two leads, and the leads and the chip are packaged and packaged by the same plastic part.

[0030] Among them, the plastic parts are made of PVC, XLPVC, XLPE, PE, PU, ​​TPE, PP, PO, silica gel, rubber and or polytetrafluoroethylene. The chip is an LED light-emitting tube chip, a photoresistor or a thermistor. In this embodiment, the chip is a thermistor. Thermistors are single-ended glass-sealed thermistors, bead-shaped glass-sealed thermistors, diode-type thermistors, bare chip-type thermistors or chip-type thermistors. The lead wire is a metal lead wire formed by stretching, and the diameter of the metal lead wire is not more than 5 cm. The surface of the plastic part is electroplated with a metal layer or covered with a metal sleeve, or pasted with a metal sticker.

no. 2 example

[0031] Second embodiment, such as figure 1 with figure 2 As shown, a production equipment for manufacturing waterproof wire components includes a first guide wheel 2, a punching die 4 located downstream of the first guide wheel 2 for punching the lead wire 1, and a punching die 4 located downstream of the punching die 4. In the guide groove 3 for conveying the punched lead wire 1, the second guide wheel 5 that guides the punched lead wire 1 in the guide groove 3, the injection molding device 6 that is positioned at the downstream of the guide groove 3 for injection molding the punched lead wire 1 and is located at the downstream of the injection device 6 for The water tank 7 where the lead wire 1 is cooled after injection molding; several NTC resistors 8 are welded at intervals between two parallel lead wires 1 to form a group of copper wires, and enter the punching die 4 through the first guide wheel 2, and the lead wires of the die 4 are punched out 1 punching, the punched...

no. 3 example

[0033] The third embodiment, a kind of production method of manufacturing waterproof strip line component, comprises:

[0034] Step 1, making lead groups, each lead group consists of two parallel lead wires and chips welded between the two parallel lead wires at intervals as required;

[0035] Step 2, debug the output speed of the lead wire and plastic;

[0036] Step 3, making unit modules, punching the leads of each lead group at the chip welding place to form several unit modules; the guide wheels and guide grooves send the punched leads to the injection molding device;

[0037] Step 4, the lead wire after injection is cooled in the water tank, and the wire is wound;

[0038] Step 5, cut off the plastic at the front of the chip at intervals, strip the leads and punch terminals and sockets.

[0039] The following takes the fabrication of a temperature sensor as an example for illustration. Specifically, the lead wire may be a copper wire, and the chip may be a thermistor. ...

Abstract

A waterproof wired component, and a device and a method for the production thereof are disclosed. The waterproof wired component comprises two lead wires (11) and a chip (12) soldered between the two lead wires, the lead wires and the chip both being enveloped and encapsulated by a same plastic element (13). The advantages of the invention are: uniform external appearance of the waterproof wired component; uniform chip positioning within the waterproof wired component; strong waterproofing capability; high degree of device automation; few human operators; low production cost; and, suitable for mass production.

Description

technical field [0001] The invention relates to a waterproof type wired component and its production equipment and method. Background technique [0002] Now in many electronic fields, it is necessary to solder the chip to the lead wire of the wire, then waterproof and insulate the chip, and punch the terminal jack seat on the lead wire to form an electronic component for use. [0003] Let's take the temperature sensor as an example to illustrate: [0004] Cut the lead wire according to the required size, weld the NTC thermistor on one end, seal it with epoxy resin, or pour it into the metal shell, and put the terminal hole seat or peeling on the other end; this method has some shortcomings: NTC temperature The inconsistency of the shape of the sensor leads to inconsistent reflection speed; low automation, many operators, low production efficiency and high cost. Contents of the invention [0005] The object of the present invention is to solve the deficiencies of the prio...
