じて通電時間が変えられていた。2. Description of the Related Art Electrofusion joints have been recently developed as joints for plastic pipes used for water and sewer pipes and gas pipes. There are various types of joints such as pipe joints, T joints, saddle joints, cap joints, etc. Each electrofusion joint is made of a molded product with a heating wire embedded in the contact surface with the pipe. Fusion is performed by inserting the pipe end into the joint or by heating the contact surface by energizing it with a constant voltage for a certain period of time with the joint pressed against the outer peripheral surface from the side of the pipe. However, the energizing time was changed according to the type and size of the joint.

法（特開昭61-175022号）なども提案されている。Conventionally, the setting of the energization time has been performed by the judgment of the operator at the site, that is, by the judgment of the appearance of the joint at the time of fusion, but recently, it is given in advance according to the size and type of the joint. A method has been started to be adopted in which an energization time is set, and an operator determines the type of energization time by identifying the type of the joint from the appearance. Regarding pipe fittings recently, energization is performed by embedding a resistor with different resistance depending on the type of fitting separately from the heating wire and detecting its resistance value or by detecting the resistance value of the heating wire itself. A method of determining the time, a method of reading the pattern of a coding tab provided integrally with the joint to obtain the energization time (Japanese Patent Laid-Open No. 61-175022), and the like have been proposed.

十分なデータが得られなくなったり、データの一部が重
複したりする。According to the method of detecting the resistance value of the resistor embedded in the joint or the heating wire, the type of joint can be identified only by inserting the connector connected to the controller into the joint insertion port. It is possible to energize for a predetermined time based on this. Also, when reading the pattern of the coding tab provided integrally with the joint, you can obtain data on the energization time simply by inserting the connector into the coding tab, but in either case you can insert the connector into the insertion port or When inserting into the tab, if the insertion is bad due to the inclination of the connector, adjustment of the insertion amount, etc., necessary and sufficient data will not be obtained from the joint, or part of the data will be duplicated.

てなるものである。For this reason, the present invention provides a joint with data means relating to energization time and insertion detection means. That is, the present invention provides a joint with data means for obtaining data on the energization time required for fusion bonding, and means for detecting whether or not the connector is inserted into the insertion port or tab, while the connector is provided. Further, a sensor for obtaining data on the energization time from the data means and a sensor for detecting the detecting means when the insertion of the connector is completed are provided.

Among them, those by holes, grooves, irregularities are preferable, and further, such It is more desirable to provide data means at the outlet. This is because it is economical because it can be integrally formed with the insertion port at the time of molding the joint, so that it is not necessary to newly provide a part for data means and a post-process is not necessary.

検出用手段は、上記データ手段のなかに組込まれるの

る。The connector 4 shown in FIG.
Are placed side by side in four rows. On the other hand, outlet 2
Has a semi-circular shape on one side and a semi-square shape on the other side. On the side surface of the half-square shape, as shown in Fig. 6, four zones are divided into front and back, excluding the frontmost zone corresponding to the micro switch 5D. In the other zone, a vertical groove 17 for data function is formed at the same level as the flat groove 18 which extends from the upper end to the middle. In the zone where the vertical groove is not formed, there is a guide portion 19 that is inclined so that the insertion from the introduction portion 18 can be performed smoothly. In the former embodiment in which the groove 6 is formed vertically, when the connector 4 is inserted, the micro switch 5 may be caught in the step and the insertion 4 may not work smoothly, whereas in the latter embodiment, it may be caught. There is an advantage that it can be inserted smoothly.

みが完了し、未完了のときは後述のCRTに表示される。In either case, when the connector 4 is inserted into the insertion port 2, the microswitches 5A, 5B, 5C detect the presence or absence of the groove 6 or the vertical groove 17 in each zone. If not, the output of 1 is transmitted to the controller 3. Therefore, depending on the presence or absence of a groove or a vertical groove in each zone, one type of insertion port 2 can obtain 8 types of combinations, and both types of insertion types can obtain 64 types of combinations. 4th
The figure shows an example of energization time set corresponding to each combination.
In any of these combinations, no groove is formed in the uppermost stage or the frontmost zone in FIG. Therefore, when the connector 4 is inserted into the insertion port 2, the micro switch 5D always outputs 1 output. In other words, the insertion is completed when the microswitch 5D outputs the output of 1, and when it is not completed, it is displayed on the CRT described later.

る。The ROM 8 stores a fusion program, and the RAM 9 stores various data such as energizing time corresponding to the type of joint, a normal value of the connector, and a complete insertion value of the connector 4. That is, before the insertion, when all the output signals from the respective microswitches 5A to 5D become 0, it is normal, otherwise it is abnormal, and when there is an abnormality, it is displayed on the CRT 8.

タイマー11は、CPU7からの出力信号により計時を開始
