Preventing Device for Disconnecting the Wire of a Connector for Test Equipment

The present invention relates to a device for preventing wire breakage of a connector for test equipment, and more specifically, to various equipment such as a production site and to test various electrical and electronic products produced in mass production or prototype in a development room, etc. Extrusion of molded parts made of flexible materials to the terminal terminal of the connector used for inspection and the wire connection area prevents disconnection or disconnection of the wire itself or the welding area between the wire and the terminal terminal during frequent disassembly of the connector. It is designed to improve the test performance and reliability of mass production or prototype.

In general, when various electrical and electronic products are produced, specific test equipments are connected to each other to test whether they have the desired performance, and performance tests are performed through a predetermined program.

At this time, the test equipment and various electrical and electronic products made of mass production or prototypes are electrically interconnected through male and female connectors having a structure that is very easy to disassemble and perform inspection.

However, the connector for test equipment used in the related art has several terminal terminals 2 in the terminal installation grooves 11 of the body mold 1 injection-molded to have a predetermined width, length and volume as shown in FIG. It is inserted and installed, and the one end of these terminal terminals 2 has the structure which fixedly installed the cable 3 wire 31 isolate | separated into several strands by soldering, welding, etc., respectively.

Thus, some of the wires 31 of the cable 3 when welded or welded to the several terminal terminals 2 inserted into the body mold 1 are always exposed to the outside and thus connected to the test equipment. When connecting or dismantling a connector (e.g. male connector) to a connector (e.g. female connector) installed in a mass production or prototype to be tested, some of the externally exposed wires are intensively pulled or bent. Due to the frequent disassembly of the wires, some of the wires may be stretched or disconnected, and in some cases, soldering or welding parts that respectively fix the wires to the terminal terminals may fall.

In this way, if a part of the wire of the test equipment connector is disconnected or separated from the terminal terminal, the inspector does not recognize the test and proceeds to test the product. As a result, the yield is reduced, as well as unnecessary maintenance and maintenance costs in the future, and in particular, there is a problem in that the reliability itself is lowered according to the test.

The present invention has been devised to solve such a conventional problem, transparent molding made of a flexible material so as to ensure flexibility in the area where the terminal terminal and wire of the connector for test equipment of various electrical and electronic products are connected By extruding the parts, it is possible to prevent the disconnection or disconnection of the wire itself or the welding part between the wire and the terminal terminal during frequent disassembly and coupling of the connector, thereby improving test performance and reliability of mass production or prototype, as well as production yield. The purpose of the present invention is to provide a device for preventing wire breakage of a connector for test equipment, which can increase the power supply and greatly reduce the maintenance cost.

An object of the present invention described above, a plurality of terminal terminals are inserted into the terminal installation groove of the injection molded body mold to have a predetermined width, length and volume, respectively, one end of these terminal terminals, each separated by several strands of cable In a connector for test equipment in which wires are soldered or welded, this can be achieved by integrally extruding a molding with a flexible material between a portion of the body mold and a portion of the cable sheath.

Therefore, it is possible to prevent the wire from being bent or pulled by the molding part during frequent disassembly of the connector, thereby preventing the wire itself or the welding part between the wire and the terminal terminal from being disconnected or disconnected. Not only can the test performance and reliability of electronic products be greatly improved, but also the production yield of the products can be increased, and the unnecessary maintenance costs that can be determined due to defective connectors can be prevented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows a front view of the connector is implemented device, the present invention, Figure 3 shows a side cross-sectional view of the connector is implemented device.

According to this, several terminal terminals 2 are inserted into the terminal installation grooves 11 of the body mold 1 injection-molded to have a predetermined width, length, and volume, and one end of these terminal terminals 2 is installed. In the connector for test equipment, in which each of the cables (3) wires (31) separated by several strands is soldered or welded,

Including the part of the body mold (1) and a part of the cable (3) sheath 32, the molded part (4) integrally extrusion molded so as to surround the outer peripheral surface of the wire 31 having a form exposed between them It features.

At this time, the molding part 4 heat-melts the PVC 50-60% native color material in order to visually grasp the state inside thereof while maintaining the flexibility of the wire, and then presses a predetermined pressure on a mold having a predetermined shape. Injection molding is carried out by injection molding, or a polydimethylsiloxane substituted at the end of the vinyl group and an organohydrogenpolysiloxane in which a hydrogen element is directly bonded to a silicon element are mixed with a platinum curing agent and injected into a mold having a predetermined shape, and then heated to a room temperature or a heat vulcanization. It is characterized in that the molded by the transparent liquid silicone rubber without the occurrence of by-products during curing by pressure molding.

In addition, in the horizontal direction of the molding part 4, a plurality of rectangular through holes 41 are formed so as to penetrate the front and rear surfaces so that the wire 31 and the molding part 4 can be flexibly bent while being molded or in use. It is an additional feature to be able to check the state of the wires through these through holes (41).

At this time, the size or number of the through-holes 41 may be determined in consideration of the size and thickness of the connector itself and the molding part 4, but is preferably formed about 2-3.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, the main technical configuration of the present invention is a part of the wire 31 and the terminal terminal (2) of the connector and the upper part of the body mold (1) and the cable (3) that are installed in the test equipment that is often forced to perform disassembly coupling The molding portion 4 is formed over a part of the outer shell 32.

That is, a cable which is soldered or welded to a part of the upper end of the body mold 1 having the terminal mounting groove 11 into which several terminal terminals 2 are inserted, and to one end of these terminal terminals 2, respectively. The molding part 3 is integrally extruded so as to surround a part of the outer shell 32 of the cable 3 including a part of the wire 31 of the three parts, and thus the outer shell 32 of the cable 3 and the body mold 1. The outer circumferential surface of the wire 31 having a form exposed between the upper ends of the c) is wrapped by the molding part 4.

In this case, the molding part 4 is molded by using 50-60% PVC primary color material or transparent liquid silicone rubber so as to visually check the state while maintaining the flexibility of the wire 31 itself to some extent. .

By the way, in the case of forming the molding part 4 by using the PVC 50-60% natural primary material, a part of the connector itself is inserted into a mold of a predetermined shape, and the PVC 50- is heated and melted at about 150-170 ° C. A method of injecting and molding 60% natural primary materials into the mold at a predetermined pressure was adopted.

In addition, when molding the molded part with a transparent liquid silicone rubber, a platinum mold is mixed with a polydimethylsiloxane substituted at the end of the vinyl group and an organohydrogenpolysiloxane in which a hydrogen element is directly bonded to a silicon element. Adopted the method of molding at room temperature or heat vulcanization by injecting into. In this case, unlike liquid silicone foam, there is no side effect when curing, so the transparent liquid silicone rubber is maintained as it is.

In the case of forming the liquid silicone rubber molding part 4 which maintains the shape of the rubber after curing using the liquid silicone, the curing time is short because the liquid silicone itself is cured within a few seconds during the room temperature or heat vulcanization pressure molding. It is possible to shorten the manufacturing process time for forming the molding part 4 in the mold, and because it is a liquid at first, it can penetrate into a complicated shape to form a molding part of an ocean shape. Therefore, it does not generate toxic gas during combustion, and has excellent heat resistance, cold resistance, non-toxicity, oil resistance, and its function is maintained even in a wide temperature range (that is, where the temperature difference is large).

Meanwhile, the molding part 4 itself includes a part of the body mold 1 and a part of the outer shell 32 of the cable 3 so that the outer circumferential surface of the wire 31 having an exposed shape therebetween surrounds the whole. When molding, the flexibility of the wire 31 itself may be lowered.

Therefore, in the present invention, the wire 31 and the molding part 4 are formed by forming approximately 2-3 rectangular through holes 41 so that the front and rear surfaces penetrate the transverse direction of the molding part 4. It is possible to visually check through these through holes 41 whether the wires are bent flexibly by 41 and any part of several wires during molding or use.

On the other hand, using the connector formed integrally with the molding unit 4 as described above, in order to inspect the state of various electrical and electronic products in the aspect or prototype state, when connecting the test equipment to the corresponding product or after separating the connectors from each other Holding the molded part (4) is to combine and disassemble the connector.

In this case, the molding part 4 includes a part of the body mold 1 and a part of the outer shell 32 of the cable 3 to maintain the outer circumferential surface of the wire 31 having an exposed shape therebetween. Therefore, since the wire 31 itself increases when the connector is coupled or separated, disconnection may be prevented, and soldering or welding with the terminal terminal 2 may be prevented from being separated from each other.

As described above, according to the present invention, the molded part is integrally extruded by a flexible material between a part of the body mold of the test equipment connector and a part of the cable jacket, so that the wire is formed by the molding part during frequent disassembly of the connector. It can prevent bending or pulling, which can prevent disconnection or disconnection of the wire itself or the welding part between the wire and the terminal terminal, thereby greatly improving the test performance and reliability of various electrical and electronic products. In addition, it is a very useful design such that it is possible to increase the production yield of the product, and also to prevent the occurrence of unnecessary maintenance costs, which can be determined as a defective product due to a poor connector.
