[Prior Art]

 FIG. 3 shows an example of the configuration of a conventional coupler-integrated sensor 90 of this type. A deep cylindrical resin case 91 is formed, and a pair of a pair of resin boards 92 and the like are set at a predetermined pitch. A terminal 93 and a temperature sensor 94 such as a thermistor connected to the terminal 93 are housed in the resin case 91 so that the terminal 93 is on the side of the opening 91a, and in this state, an appropriate amount of epoxy resin molding material 95 Is injected from the opening portion 91a and cured to form.

[Problems to be solved by the device]

 However, in the above-described conventional coupler-integrated sensor 90, the molding material 95 is injected through the opening 91a, and therefore the molding material 95 is attached to the terminal 93 on the opening 91a side at the time of injection. Accidents that result in poor contact are easily caused, and the work to prevent adhesion becomes extremely complicated, and inspection for that is also required, which causes the problem of reducing the production efficiency of the coupler-integrated sensor 90. , The solution of this point was supposed to be an issue.

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned conventional problems, the present invention is a male coupler in which a terminal is disposed near the opening of a deep cylindrical resin case, and a resin member is molded near the bottom. In the coupler-integrated sensor in which the embedded sensor is embedded, a molding material injection port that opens to the opening side is provided protruding on the side surface of the resin case, and the molding material injection port is By providing a coupler-integrated sensor characterized by having a gauge that indicates an appropriate amount of injection of the molding material, it is assumed that the molding material does not adhere to the terminals during the assembly process. This is to solve the conventional problems.

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 is a coupler-integrated sensor according to the present invention. The coupler-integrated sensor 1 is a deep cylindrical resin case 2 near the bottom surface of which the sensor 3 is made of, for example, epoxy resin. Similar to the conventional example, a pair of terminals 5 embedded in the molding material 4 and connected to the sensor 3 are arranged near the opening of the resin case 2 to form a male coupler.

However, according to the present invention, the resin case 2 is divided into, for example, a case upper half 21 and a case lower half 22, and at this time, a part of the opening of the case lower half 22 is laterally opened. The molding material injection port 23 is formed at the joint between the case upper half portion 21 and the case lower half portion 22 by molding so as to project to the above. At this time, the molding material injection port 23 is The opening is in the same direction as the opening of the resin case 2.

Further, in the molding material injection port 23, a gauge 24 is integrally provided, for example, as a boss when the case lower half portion 22 is formed, and a tip 24 a of the gauge 24 has a tip 24 a. The height H from the bottom surface of the tip 24a is set so that it can be easily viewed from the opening of the inlet 23, and the molding material 4 in the resin case 2 assembled with the case upper half 21 is filled. It is said to indicate the limit of quantity.

When the resin case 2 is divided into the case upper half portion 21 and the case lower half portion 22 as described above, the case upper half portion 21 and the case lower half portion 22 have a hook structure 25 or the like. If the terminal 5 and the sensor 3 can be attached to the upper half 21 of the case, the assembling work becomes easy, which is preferable.

When assembling the coupler-integrated sensor 1 having the above-described configuration, first, the terminal 5 and the sensor 3 are attached to the case upper half 21, and in this state, the case upper half 21 and the case lower half 22 are connected. Is hooked with the hook structure 25. When assembled in this way, the resin case having the molding material injection port 23 that projects laterally is formed at the joint between the case upper half 21 and the case lower half 22 due to the configuration of the present invention. 2 is obtained, the resin case 2 is held with the mold material injection port 23 facing upward, and the mold material 4 is injected from this mold material injection port 23 until the tip 24a of the gauge 24 is reached. This completes the assembly.

Next, the operation and effect of the coupler-integrated sensor 1 of the present invention having the above-described structure will be described. By providing the molding material injection port 23, the molding material injection port 23 Since the molding material 4 can be injected, the molding material 4 is completely prevented from adhering to the external wiring of the terminal 5 to cause insulation failure.

Further, since the gauge 24 is provided in the mold material injection port 23, even when the mold material 4 is injected from the side of the resin case 2, it is extremely easy to determine an appropriate injection amount. It will be possible to know, and stable quality will be maintained without causing excess or deficiency of the injection amount.

In the above description, the resin case 2 is divided into the case upper half 21 and the case lower half 22, and the present invention is not limited to this. As shown in FIG. 2, a mold material injection port 7 and a gauge 8 may be integrally provided in the resin case 6 by using a slide mold or the like at the time of shaping. The point is that the molding material injection port (7 or The gist of the present invention resides in that by providing 23), the injection can be performed without attaching the molding material to the terminal.

[0013]

[Effect of the device]

 As described above, according to the present invention, the molding material injection port opening to the opening side is provided on the side surface of the resin case, and an appropriate amount of the molding material injection amount is provided in the molding material injection port. By using a coupler-integrated sensor that is equipped with a gauge that displays, it is possible to eliminate the problems such as contact failure in the subsequent mounting on the vehicle due to the molding material adhering to the terminals during the molding material injection process. At the same time, the process is simplified, and excellent effects are obtained in quality improvement and productivity improvement.
