The pair of injection holes 511 and 521 are located on one short side 413 side (the left side in FIGS. 4B and 4C) of the cross section of the cover member 41.

  In the following description, the “cross section including the injection holes 511 and 521 and orthogonal to the extending direction of the cable 3” is simply referred to as “cross section”.

  In the present embodiment, the pair of injection holes 511 and 521 are directed to corners 411 c and 412 c located at both ends of one short side 413 in the cross section of the cover member 41, respectively.

Are directed to the corners 412c of the cover member 41 on the second member 412 side, respectively.

  In the molding process, the molten resin 420 is injected toward the corners 411c and 412c of the cover member 41. As shown in FIG. 4B, the molten resin 420 injected into the mold 5 mainly has two directions. Branches into and flows.

  As shown in FIG. 4 (c), one molten resin 420 mainly injected from the injection hole 511 of the upper mold 51 is formed between the cover member 41 and the inner surface 51 a of the upper mold 51. It flows along one long side 415 in the cross section. The other molten resin 420 injected mainly from the injection hole 521 of the lower mold 52 is between the cover member 41 and the inner surface 52a of the lower mold 52 along the other long side 416 in the cross section of the cover member 41.

Therefore, when making a product, the pair of protrusions is removed. . The pair of injection hole marks 421a shown in FIGS. 1 and 2C are marks formed when the pair of protrusions are removed.

(Comparative example)
Next, a comparative example of the sensor module 1 according to the embodiment of the present invention will be described with reference to FIG.

  FIG. 5 is a comparative example of the sensor module 1 according to the embodiment of the present invention, and is a cross-sectional view showing how molten resin flows in the mold 6.

  The mold 6 according to this comparative example is configured by combining an upper mold 61 and a lower mold 62 in the same manner as the mold 5 according to the embodiment. However, it differs from the mold 5 in the embodiment in that the pair of injection holes 611 and 612 is provided only on the upper mold 51 side. More specifically, the pair of injection holes 611 and 612 are located on one long side 415 side (upper side in FIG. 5) in the cross section of the cover member 41.

  Also in the molding process according to this comparative example, the molten resin 420 injected into the mold 6 flows mainly in two directions. One molten resin 420 mainly injected from the injection hole 611 flows between the cover member 41 and the inner surfaces 61 a and 62 a of the mold 6 along one short side 413 in the cross section of the cover member 41. The other molten resin 420 injected mainly from the injection hole 612 flows between the cover member 41 and the inner surfaces 61 a and 62 a of the mold 6 along the other short side 414 in the cross section of the cover member 41.

  The molten resin 420 that flows along one short side 413 in the cross section of the cover member 41 and the molten resin 420 that flows along the other short side 414 in the cross section of the cover member 41 are cross sections of the cover member 41. At the other long side 416 side. At this time, the cover member 41 is pressed toward the pair of injection holes 611 and 612 by the collision pressure when the molten resin 420 joins.

  In the embodiment, the molten resin 420 injected into the mold 5 flows along a pair of long sides 415 and 416 in the cross section of the cover member 41, and the other short side 414 (a pair of injection holes 511 and 521). In the present modification, the molten resin 420 injected into the mold 6 is a pair of short portions in the cross section of the cover member 41. It flows along the sides 413 and 414 and merges on the other long side 416 (long side opposite to the long side 415 facing the pair of injection holes 611 and 612).

  Therefore, the cover member 41 according to this comparative example receives the pressing force due to the collision pressure when the molten resin 420 merges on the long side 416 side having a lower rigidity than the short sides 413 and 414. The heat of the molten resin 420 is easily transmitted to the sensor 2.

(Operation and effect of the embodiment)
According to the embodiment described above, the following operations and effects can be obtained.

(1) In the molding process of the sensor module 1, the molten resin 420 injected from the one short side 413 side in the cross section of the cover member 41 covers the space between the cover member 41 and the inner surfaces 51 a and 52 a of the mold 5. Since the fluid flows along the pair of long sides 415 and 416 in the cross section of the member 41 and merges on the other short side 414 side, the cover member 41 applies the pressing force due to the collision pressure when the molten resin 420 merges to the long side It can be received on the short side 414 side having higher rigidity than 415 and 416, deformation due to the pressing force is suppressed, heat of the molten resin 420 is hardly transmitted to the sensor 2, and damage to the sensor 2 can be avoided. .

(2) Since the mold 5 is provided with a pair of injection holes 511, 521 on one short side 413 side in the cross section of the cover member 41, it is between the cover member 41 and the inner surface 51 a of the upper mold 51. And the flow rate of the molten resin 420 flowing through the flow path between the cover member 41 and the inner surface 52a of the lower mold 52 can be equalized.

(3) The pair of injection holes 511 and 521 are directed to the corners 411c and 412c in the cross section of the cover member 41, and in the molding process, the molten resin 420 is injected toward the corners 411c and 412c. Can receive the injection pressure of the molten resin 420 at the corner portions 411c and 412c having high rigidity, and can suppress deformation due to the injection pressure of the molten resin 420.

(4) Since the cover member 41 has a gap 410 between the sensor 2 housed in the housing space 410c and the cover member 41 is deformed by receiving a pressing force from the molten resin 420 in the molding process. Even so, the pressing force applied to the sensor 2 can be suppressed, and the heat of the molten resin 420 is hardly transmitted.
