Description

  The present invention relates to a connector that can also be used in construction sites, work sites, industrial equipment, electronic equipment, audio / video equipment, aviation, and communication.

  Various connectors are used frequently at construction sites and work sites. Many connectors are also used in industrial equipment, electronic equipment, audio / video equipment, aviation, and communications. To use either connector, it must be connected to a cable. Conventionally, the connector and the cable are connected by first cutting a predetermined amount of the cable sheath from the end portion to expose each covered electric wire in the cable. Next, an insulating cap is inserted into each covered electric wire, and a predetermined amount of the insulator of each covered electric wire is shaved from the end portion to expose each conductive wire. Next, when using a crimp terminal, the crimp terminal is crimped to the conductive wire, and the crimp portion is covered with an insulating cap, and then the crimp terminal is connected to each terminal portion of the connector. In the case of the crimping method, the exposed conductive wires and dedicated terminal pins are crimped with a tool and inserted into the connector terminal holes respectively, or the exposed conductive wires and the connector terminal portions are integrated. , Both are crimped with a tool. When using solder, each exposed conductive wire and each terminal portion of the connector are connected by soldering.

  However, there is a problem that mass production is difficult because the above-described cable connection work is performed manually. Also, the cable connected to the connector often has a plurality of covered electric wires, and there is a problem that it takes a considerable time to expose the conductive wire from the cable. For example, the type 1 and type 2 cables have a structure in which the conductive wire can be exposed if the sheath and the insulation of the covered electric wire are removed, but it still takes time. On the other hand, the three types of cables are provided with a high-strength reinforcing canvas in the sheath for impact resistance, wear resistance, and trauma resistance, and it takes more time than the type 1 and type 2 cables. Has the problem. In addition, a cable having a two-digit or three-digit coated electric wire has an excessive amount of the covered electric wire, and the conductive wire is very difficult to be exposed. In addition, such a cable often uses a string, paper, or the like that binds a large amount of covered electric wires inside, and it is very troublesome to remove them. In addition, there are cables using a high hardness material such as vinyl, natural rubber or ethylene propylene as the sheath material, and in addition to the work of connecting the cable and the connector, the work of stripping the conductive wire was very difficult.

  In addition, it is inevitable to use a blade for scraping the sheath or for stripping the conductive wire. When the sheath or the insulator is cut with a blade, there is a problem that a fine laceration is easily formed on the surface of the conductive wire. This laceration spreads when force is applied, causing a break in the conductive wire. Although the dedicated tool can reduce the possibility of creating a laceration, it is difficult to expose the conductive wire without creating a laceration as long as the blade is used. Moreover, the method of crimping and connecting the conductive wires has a problem that it is very easy to disconnect because a great force is applied to the conductive wires at the time of crimping.

  Moreover, since the sheath and the insulator are scraped off, there has been a problem that a large amount of debris is generated at the work site. Large amounts of debris such as conductive wires, sheaths, insulators, and the like are generated, but in addition, cloth for reinforcing canvas, paper waste of cable binding paper, and the like are also generated. These fine debris and the like may enter the wiring and circuits, etc., which may cause malfunctions and accidents of equipment. For this reason, it is necessary to always clean the debris during cable connection work, and there is a problem that work efficiency is very poor. In addition, since a large amount of dust is generated, there is a problem that the cost of processing the dust is increased.

  In addition, various tools such as crimp terminals, insulation terminal caps, crimpers, solder, solder tools, insulation tubes, drivers, and insulation tapes were required to connect the cable and connector. It took a long time to master each tool, and there was a problem that everyone could not easily connect.

  In recent years, although use has been avoided, there are many cases where solder is used for cable connection. When soldering, if other solder wires are tangled and soldered, it may cause a failure or an accident, so it is necessary to work with great care. However, if it is a two-core or three-core wire, it will not be a difficult task, but there are cables with two-digit and three-digit cores for industrial machinery and communication cables. It will be hard work. In addition, in order to accurately connect such special cables, considerable technology is required, which makes it difficult to manufacture and causes an increase in cost.

  From the above, it is very easy to connect connectors and cables, and even those without skilled skills can connect them accurately and reliably, greatly reducing work time and keeping the work site clean. Therefore, the development of a connector that can greatly reduce the disconnection rate of the cable has been desired.

When the adjustment member is provided, the connector 2 and the cable 56 can be connected without using the cable fixing auxiliary tool 34, but the cable fixing auxiliary tool 34 may be used.

  The connector 2 according to the present invention preferably has a structure in which the cable fixing auxiliary tool 34 or the insertion auxiliary tool 38 contacts a part of the inner peripheral surface of the cover main body 26 when the connector main body 6 and the cover portion 24 are screwed together. Since the connector 2 according to the present invention has a structure in which the conductive wire of the cable 56 is inserted and connected to the connection pin 14, a force for inserting the conductive wire into the connection pin 14 is required. The cable 56 may be manually inserted into the connection pin 14, but if the insertion direction of the cable 56 and the protruding direction of the connection pin 14 are deviated, the connection pin 14 may be broken or the connection pin 14 may break through the covered electric wire 58. Moreover, since a considerable force is required to insert the cable 56, the work efficiency may be deteriorated. On the other hand, since the connector body 6 and the cover portion 24 have a screwed structure, the track of the cover body 26 is always in a certain direction. Therefore, when the connector main body 6 and the cover portion 24 are screwed together, the cable fixing auxiliary tool 34 or the insertion auxiliary tool 38 is in contact with a part of the inner peripheral surface of the cover main body 26, and the cable fixing auxiliary tool 34 or the insertion auxiliary tool. The track 38 is made to coincide with the cover main body 26 so that the connection pin 14 is inserted into the conductive wire accurately and reliably. As a method of bringing the cable fixing auxiliary tool 34 or the insertion auxiliary tool 38 into contact with the inner peripheral surface of the cover main body 26, as shown in FIG. 4, the inner peripheral surface of the cover main body 26 is formed in a curved shape, and FIG. As shown, the end of the holding member 54 may be rounded. Other structures and configurations may be used, and it is even better if the cover body 26 does not hinder the screwing rotation. Further, when the connector main body 6 and the cover portion 24 are completely screwed together, the cable fixing auxiliary tool 34 and the exterior body 4 are formed so that the bottom plate 44 of the insertion auxiliary tool 38 and the connector main body 6 at the base of the connection pin 14 are in contact with each other. It is even better if it is done.

  The above is the description of the connector 2 according to the present invention, but various conditions and settings can be changed without departing from the object of the present invention.

  Next, a method for connecting the connector 2 and the cable 56 according to the present invention will be described. First, the end of the cable 56 to be connected is cut. At this time, it is preferable to cut the cut surface of the cable 56 and the cut surface of the covered electric wire 58 to be the same surface. Then, as shown in FIG. 11, the cable 56 is passed from the outside of the cover body 26 of the cable through hole 30.

  When using the auxiliary fixture 48 shown in FIG. 7, the holding member 54, the waterproof member 52, and the fastening member 50 are passed through the cable 56 in this order. When the auxiliary attachment 48 is passed through the cable 56, it may be integrated or may be separated and passed separately, but after passing through the cable 56, the auxiliary attachment 48 is integrated, 11, the fastening member 50 is arranged so as to be flush with the cut surface of the cable 56.

  Next, the insertion assisting tool 38 is inserted into the cut surface of the cable 56. As shown in FIG. 12, when the insertion assisting tool 38 is inserted until the cut surface of the cable 56 and the bottom plate 44 are in contact with each other, the guide portion 16 of the auxiliary mounting tool 48 and the convex portion 36 of the insertion assisting tool 38 coincide with each other. Installation of the cable fixing auxiliary tool 34 is completed.

  Next, as shown in FIG. 13, the guide portion 16 of the cable fixing auxiliary tool 34 and the guide portion 16 of the connector main body 6 are matched. Then, the cable fixing auxiliary tool 34 is slightly pushed into the connector main body 6, and the cover main body 26 and the connector main body 6 are screwed together. When the connector body 6 and the cover body 26 are screwed together, the space between the connector body 6 and the cover body 26 is narrowed, and the cable fixing auxiliary tool 34 is pushed in by the cover body 26. At this time, the cable fixing auxiliary tool 34 is moved in a certain direction by the guide portion 16, and the insertion auxiliary tool 38 comes close to the distal end portion of the connection pin 14. Further, when the connector body 6 and the cover body 26 are screwed together, the connection pin 14 passes through the connection pin through hole 46 and is inserted into the conductive wire. When the connector body 6 and the cover body 26 are completely screwed together, the connection between the connector body 6 and the cable 56 is completed.

  As described above, the connector 2 and the cable 56 according to the present invention can be connected simply by screwing the connector main body 6 and the cover main body 26 after attaching a predetermined member to the cable 56, so that the connecting operation is very easy. Thus, no skill is required and the connection can be performed accurately.

  In the above description, the male and female connector plugs and connector bodies have been mainly described. However, the connector according to the present invention is also applied to cables used in industrial equipment, electronic equipment, audio / video equipment, aviation, and communication.
