Description

  The present invention relates to a molding die, a method for producing a resin molded product using the same, and a resin molded product.

  Some conventional resin molded products have a body and a terminal. The body has a base, an annular side wall provided on the base, and a partition provided on the base. The partition part divides the internal space of the side wall into first and second spaces. The terminal includes first, second, third, and fourth segment portions and a frame that connects the first, second, third, and fourth segment portions. The distal end portion of the first section is embedded in the partition portion such that the end surface is exposed to the first space. The distal end portion of the second section is embedded in the partition portion so that the end surface is exposed to the second space. The third section is embedded in the side wall so that the end surface is exposed to the first space. The fourth section is embedded in the side wall so that the end surface is exposed to the second space.

  The resin molded product is manufactured as follows. The base end of the first section is between the inner surface of the first protrusion of the first mold and the protrusion of the second mold, and the base end of the second section is the second protrusion of the first mold. And sandwiching between the inner surface of the first portion and the convex portion of the second mold, and arranging the tip portions of the first and second section portions and the third and fourth section portions in the cavities of the first and second molds. Let Thereafter, an insulating resin is injected into the cavity and cured. The insulating resin becomes the body, and the first and second convex portions of the first mold form the first and second spaces of the body. The distal end portions of the first and second segment portions of the terminal are embedded in the partition portion of the body, and the third and fourth segment portions of the terminal are embedded in the side wall of the body. Thereafter, the first, second, third, and fourth section portions are separated from the frame.

Japanese Patent Application Laid-Open No. 07-099016

  The third and fourth sections are positioned and held in the cavity by the proximal ends of the first and second sections being sandwiched between the first and second molds. That is, since the first and second section portions for positioning and holding the third and fourth section portions in the cavity are indispensable, the terminals are increased in size. Therefore, it has been difficult to downsize the resin molded product.

  The present invention was devised in view of the above circumstances, and an object of the present invention is to easily position and hold the terminal section of the terminal in the cavities of the first and second molds and to form a resin. An object of the present invention is to provide a molding die capable of downsizing a molded product, a method for producing a resin molded product using the mold, and a resin molded product.

  In order to solve the above-described problems, the molding die of the present invention includes first and second dies having cavities that can accommodate at least the terminal sections of the terminals. The first mold includes a convex portion that can contact the first surface of the section portion, and a protrusion that is provided at an interval from the convex portion. The protrusion is a first edge that is a base-side edge of the protrusion and is capable of coming into contact with a second surface opposite to the first surface of the section, and a second edge that is an edge on the tip side of the protrusion. An edge, and an inclined surface or a curved surface that is inclined so as to be separated from the convex portion from the first edge to the second edge.

  In the case of such a molding die, the first surface of the terminal section of the terminal is in contact with the convex portion of the first mold, and the second surface of the section is in contact with the first edge of the projection of the first mold. Make contact. As a result, since the segment is sandwiched between the convex portion of the first mold and the first edge of the projection, the segment of the terminal can be easily positioned and held in the cavity by the first and second molds. . Further, since the section is sandwiched between the convex portion of the first mold and the first edge of the protrusion, it is possible to suppress the terminal from being moved or deformed by the injection pressure when the resin is injected into the cavity. Further, it is not necessary to separately provide a portion for positioning the section portion in the cavities of the first and second molds in the terminal. For this reason, since the terminal does not increase in size, the resin molded product can be reduced in size. In addition, since the section is guided between the convex portion of the first mold and the first edge of the projection by the inclined surface or the curved surface, the section portion is guided by the convex portion of the first mold and the first edge of the projection. Can be easily inserted between. Furthermore, the inclined surface of the protrusion is inclined so as to be separated from the section. Alternatively, the curved surface of the protrusion is curved so as to be separated from the section. That is, since a space that forms a part of the cavity is formed between the second surface of the section and the inclined surface or curved surface of the protrusion, the resin can flow into the space. Therefore, the second surface can be embedded in the resin even though the second surface of the section is brought into contact with the protrusion.

  The first and second molds are configured such that the terminal main body of the terminal and the section portion connected to the terminal main body and bent with respect to the terminal main body can be accommodated in the cavity. Is possible.

  In the case of such a molding die, the section is bent at a substantially right angle with respect to the terminal main body, so that it is easily affected by the injection pressure when the insulating resin is injected into the cavity. However, since the intercept portion is sandwiched between the convex portion and the first edge of the protrusion, it is possible to suppress the intercept portion of the terminal from being moved or deformed by the injection pressure.

  The first and second molds can be configured such that the terminal body is accommodated in the cavity and can be partially sandwiched.

  In the case of such a molding die, the first and second molds sandwich the terminal body in the cavity, so that the terminal can be moved or deformed by the injection pressure when the resin is injected into the cavity. Further suppression can be achieved.

  The method for producing a resin molded product according to the present invention is a method for producing a resin molded product using the molding die. In this method, a segment portion of a terminal is inserted between the convex portion and the projection of the first mold, the first surface of the segment portion is the convex portion, and the second surface is the projection. By contacting the first edge, the section is sandwiched between the convex portion and the first edge. In this state, the first and second molds are clamped, and at least the section of the terminal is disposed in the cavities of the first and second molds. Insulating resin is injected into the cavity and cured, and the section is embedded in the insulating resin.

  In the case of the manufacturing method of this aspect, only by inserting the segment part of the terminal between the convex part of the first mold and the projection, the segment part is formed by the convex part of the first mold and the first edge of the projection. It is pinched. Accordingly, the terminal section can be easily positioned and held in the cavity by the first and second molds. Further, since the section is sandwiched between the convex portion of the first mold and the first edge of the protrusion, it is possible to suppress the terminal from being moved or deformed by the injection pressure when the resin is injected into the cavity. In addition, it is not necessary to provide a portion for positioning the section in the first and second mold cavities in the terminal. For this reason, since the terminal does not increase in size, the resin molded product can be reduced in size. Furthermore, the insulating resin injected into the cavity does not flow into the space between the second surface of the section and the inclined surface or curved surface of the protrusion. For this reason, the second surface can be embedded in the resin even though the second surface of the section is brought into contact with the protrusion.

  When the section of the terminal is disposed in the cavities of the first and second molds, the terminal body of the terminal, the section connected to the terminal body and bent with respect to the terminal body, Can be placed in the cavity.

  In the case of the manufacturing method of this aspect, since the section is bent at a substantially right angle with respect to the terminal body, it is easily affected by the injection pressure when the insulating resin is injected into the cavity. However, since the intercept portion is sandwiched between the convex portion and the first edge of the protrusion, it is possible to suppress the intercept portion of the terminal from being moved or deformed by the injection pressure.

  The first and second molds can accommodate the terminal body in the cavity and can be partially sandwiched.

  In the case of the manufacturing method of this aspect, since the terminal body is sandwiched between the first and second molds in the cavity, the terminal is further moved or deformed by the injection pressure when the resin is injected into the cavity. Can be suppressed.

  The resin molded product of the present invention includes a terminal and a body. The terminal has a section. The section has a first surface and a second surface opposite to the first surface. The body includes a base, a side wall standing on the base and having a wall surface, and a recess provided in the side wall. The section is embedded in the side wall so that the first surface is exposed from the wall surface of the side wall. The concave portion is an opening-side edge of the concave portion and is in contact with the second surface of the section portion, a second edge that is a bottom-side edge of the concave portion, and the first edge to the first edge. It has an inclined surface or a curved surface that is inclined so as to be separated from the section portion over two edges.

  In the case of such a resin molded product, the first surface of the terminal section of the terminal is exposed from the wall surface of the side wall of the body. The second surface of the section is in contact with the first edge of the recess of the body. Therefore, the convex portion of the first mold is brought into contact with the first surface of the section portion, while the first edge of the projection of the first mold for forming the concave portion is brought into contact with the second surface of the section portion. be able to. That is, since the section can be sandwiched between the convex portion of the first mold and the first edge of the projection, the terminal section of the terminal is easily positioned in the cavity in the first and second molds. Can be retained. Further, since the section portion can be sandwiched between the convex portion of the first mold and the first edge of the projection, the terminal is prevented from being moved or deformed by the injection pressure when the resin is injected into the cavity. be able to. In this way, since the section is sandwiched between the convex portion of the first mold and the first edge of the projection, a portion for positioning and holding the section within the cavities of the first and second molds is a terminal. There is no need to provide it. For this reason, since the terminal does not increase in size, the resin molded product can be reduced in size. Further, the inclined surface of the concave portion of the body is inclined so as to be separated from the intercept portion from the first edge to the second edge. Alternatively, the curved surface of the concave portion of the body is curved so as to be separated from the section from the first edge to the second edge. Therefore, the second surface can be embedded in the body even though the second surface of the section is brought into contact with the protrusion of the first mold.

  The terminal may further include a terminal body embedded in the base. The section may be connected to the terminal body and bent with respect to the terminal body.

  The body may further include a receiving space defined by the side wall. The wall surface may be a wall surface on the housing space side.

The first edge 13c1 is an edge on the base side of the protrusion 13c of the inclined surface 13c3. The distance between the first edge 13c1 and the convex portion 11 is substantially the same as the distance from the first surface 241a to the second surface 242a of the intercept portion 240a (that is, the thickness dimension of the intercept portion 240a). The second edge 13c2 is an edge on the tip side of the protrusion 13c of the inclined surface 13c3.

  The second mold 20 has a recess 21 and a protrusion 22. The recess 21 has a shape corresponding to the outer shape of the base 110 of the body 100. The protrusion 22 is provided on the bottom surface of the recess 21. The protrusion 22 has a center portion 22a and a plurality of branch portions 22b.

Partition C1. The cavity C1 has a shape corresponding to the outer shape of the body 100 and the connecting portions 250a, 260a, 220b, and 220c protruding from the body 100.

  The third mold 30 has substantially the same shape as the first mold 10 except that the third mold 30 is different from the first mold 10 in that the sprue 14 is not provided. The fourth mold 40 has substantially the same shape as the second mold 20 except that the fourth mold 40 is different from the second mold 20 in that it does not have the protrusions 22 and has the sprue 42. In a state where the third and fourth molds 30 and 40 are combined with each other, the convex portion 31, the concave portion 32, the projections 33 a, 33 b and 33 c, and the concave portion 41 define the cavity C 2 of the third and fourth molds 30 and 40. Partition. The cavity C2 has a shape corresponding to the outer shape of the resin molded product.

  Hereinafter, a method of manufacturing the resin molded product using the first and second molds 10 and 20 and the third and fourth molds 30 and 40 will be described with reference to FIGS. 6A to 6C. First, the intercept portion 220a of the terminal 200a is inserted between the convex portion 11 and the projection 13a, the intercept portion 230a of the terminal 200a is inserted between the convex portion 11 and the projection 13b, and the intercept portion 240a of the terminal 200a is convex. It inserts between the part 11 and the protrusion 13c. Then, the first surface 221a of the intercept portion 220a partially abuts on the convex portion 11, and the second surface 222a of the intercept portion 220a abuts on the first edge 13a1 of the protrusion 13a. That is, the section 220a is sandwiched between the convex portion 11 and the first edge 13a1 of the projection 13a (see FIG. 6A). At this time, the second edge 13a2 and the inclined surface 13a3 of the protrusion 13a do not contact the second surface 222a of the section 220a. The first surface 231a of the section 230a partially abuts on the convex portion 11, and the second surface 232a of the section 230a abuts on the first edge 13b1 of the protrusion 13b. That is, the section 230a is sandwiched between the convex portion 11 and the first edge 13b1 of the projection 13b (see FIG. 6C). At this time, the second edge 13b2 and the inclined surface 13b3 of the protrusion 13b do not contact the second surface 232a of the section 230a. The first surface 241a of the intercept portion 240a partially abuts on the convex portion 11, and the second surface 242a of the intercept portion 240a abuts on the first edge 13c1 of the protrusion 13c. That is, the segment 240a is sandwiched between the convex portion 11 and the first edge 13c1 of the projection 13c (see FIG. 6C). At this time, the second edge 13c2 and the inclined surface 13c3 of the protrusion 13c do not contact the second surface 242a of the section 240a.

  Thereafter, the first and second molds 10 and 20 are clamped. Then, the terminals 200a, 200b, and 200c are accommodated in the cavities C1 of the first and second molds 10 and 20, and the terminal bodies 210a, 210b, and 210c of the terminals 200a, 200b, and 200c are the convex portions of the first mold 10. 11 and the protrusion 22 of the second mold 20. Specifically, the terminal main body 210 a is sandwiched between the convex portion 11 and a part of the branch portions 22 b of the protrusion 22. The terminal main body 210a and the terminal main body 210b are sandwiched between the convex portion 11 and another branch portion 22b of the branch portions 22b of the protrusion 22. The terminal main body 210 a and the terminal main body 210 c are sandwiched between the convex portion 11 and the remaining branch portion 22 b of the branch portions 22 b of the protrusion 22.

  Thereafter, the first insulating resin R1 is injected from the sprue 14 into the cavities C1 of the first and second molds 10 and 20, and filled in the cavities C1. Thereafter, the first insulating resin R1 is cured. In this way, the first insulating resin R1 is molded as the body 100. A recess 140 corresponding to the shape of the protrusion 22 is formed on the second surface 222a of the body 100, and recesses 130a, 130b, and 130c corresponding to the shape of the protrusions 13a, 13b, and 13c are formed on the side wall 120 of the body 100. In this way, the terminals 200a, 200b, and 200c are insert-molded into the body 100 (first insulating resin R1).

  Specifically, the terminal bodies 210 a, 210 b, and 210 c are embedded in the base 110 of the body 100. Accordingly, the first surfaces 211a, 211b, and 211c of the terminal bodies 210a, 210b, and 210c are partially exposed from the first surface 111 of the body 100. The second surface 212a of the terminal body 210a is partially exposed from a part of the branch portion 142 of the recess 140 of the body 100. The second surfaces 212a and 212b of the terminal bodies 210a and 210b are partially exposed from another branch 142 of the recess 140 of the body 100. The second surfaces 212a and 212c of the terminal bodies 210a and 210c are partially exposed from the remaining branches 142 of the recess 140 of the body 100. Portions other than the tip portions of the connection portions 250a, 260a, 220b, and 220c are embedded in the base 110 of the body 100, and the tip portions protrude outside the body 100. The sections 220a, 230a, and 240a are embedded in the side wall 120 of the body 100. As a result, the first surfaces 221 a, 231 a, and 241 a of the sections 220 a, 230 a, and 240 a are exposed from the wall surface 121 of the sidewall 120. The second surfaces 222a, 232a, 242a of the sections 220a, 230a, 240a are in contact with the first edges 131a, 131b, 131c of the recesses 130a, 130b, 130c, and the inclined surfaces 133a, 133b, 133c of the recesses 130a, 130b, 130c. Covered with resin inside. Thereafter, the first and second molds 10 and 20 are released, and the body 100 and the terminals 200a, 200b, and 200c are taken out.

  Thereafter, the body 100 and the terminals 200a, 200b, and 200c are accommodated in the cavity C2 of the third and fourth molds 30 and 40, and the recess 140 of the body 100 is closed with the fourth mold 40. Thereby, a space is defined by the fourth mold 40 and the concave portion 140 of the body 100. Thereafter, the second insulating resin R2 is injected from the sprue 14 into the space to fill the space (concave portion 140). Thereafter, the second insulating resin R2 is cured. In this way, the second insulating resin R2 is molded as the seal portion 300. Thereby, the seal part 300 is fixed to the body 100 and the terminals 200a, 200b, and 200c. Thereafter, the third and fourth molds 30 and 40 are released, and the body 100, the terminals 200a, 200b, and 200c, and the seal portion 300 are taken out. A resin molded product is manufactured as described above.

  In the case of the resin molded product, the section 220a is sandwiched between the convex portion 11 of the first mold 10 and the first edge 13a1 of the projection 13a when the body 100 is molded. The section 230a is sandwiched between the convex portion 11 of the first mold 10 and the first edge 13b1 of the projection 13b. The section 240a is sandwiched between the convex portion 11 of the first mold 10 and the first edge 13c1 of the projection 13c. In addition, the terminal bodies 210 a, 210 b, and 210 c are sandwiched between the convex portion 11 of the first mold 10 and the protrusion 22 of the second mold 20. Therefore, since the terminal 200a can be easily positioned and held in the cavity C1, the terminal 200a can be reduced in size and the resin molded product can be reduced in size compared to the case where a separate positioning holding portion is provided in the terminal 200a. Can be achieved. In addition, since the sections 220a, 230a, and 240a are bent at a substantially right angle with respect to the terminal body 210a, they are easily affected by the injection pressure when the first insulating resin R1 is injected into the cavity C1. However, since the intercept portions 220a, 230a, and 240a are sandwiched between the convex portion 11 and the first edge of the projection as described above, the intercept portions 220a, 220b, and 200c of the terminals 200a, 200b, and 200c are caused by the injection pressure. Can be prevented from moving or deforming. In addition, since the section 220a is guided between the convex portion 11 and the first edge 13a1 of the projection 13a by the inclined surface 13a3 of the first mold 10, the section 220a is guided between the convex portion 11 and the first edge 13a1. Can be easily inserted between. The same applies to the intercepting portions 230a and 240a.

  Further, the inclined surfaces 13 a 3, 13 b 3, 13 c 3 of the protrusions 13 a, 13 b, 13 c of the first mold 10 are inclined so as to be separated from the convex portion 11. When the sections 220a, 230a, 240a are sandwiched between the convex portion 11 and the first edges 13a1, 13b1, 13c1 of the projections 13a, 13b, 13c, the inclined surfaces 13a3, 13b3, 13c3 and the sections 220a, 230a , 240a, a space forming a part of the cavity C1 is formed between the second surfaces 222a, 232a, and 242a. Since the first insulating resin R1 can be introduced into the space, the second surfaces 222a, 232a, and 242a of the sections 220a, 230a, and 240a are connected to the first edges 13a1, 13b1, and 13c1 of the protrusions 13a, 13b, and 13c. Despite the contact, the second surfaces 222a, 232a, 242a can be embedded in the resin.

  Further, when the body 100 is molded, the terminals 200 a, 200 b, and 200 c are sandwiched between the convex portion 11 of the first mold 10 and the protrusion 22 of the second mold 20. Therefore, a recess 140 corresponding to the outer shape of the protrusion 22 is formed on the second surface 112 of the body 100. Since the concave portion 140 is filled with the seal portion 300, the insulating property, waterproof property, and dustproof property of the resin molded product can be improved without increasing the thickness dimension of the resin molded product. In addition, since the seal portion 300 is filled in the recess 140 and is fixed to the body 100 and the terminals 200a, 200b, and 200c, it is difficult to peel off.

  The concave portion 140 has a shape having a central portion 141 and a plurality of branch portions 142 extending radially from the central portion 141. The branch part 142 has an elongated shape as described above. For this reason, when the sealing part 300 is molded, the second insulating resin R2 flows into the branch part 142 from the central part 141 by injecting the second insulating resin R2 into the central part 141. That is, since the fluidity of the second insulating resin R2 is improved, the second insulating resin R2 (seal part 300) can be easily filled into the recess 140.

  In addition, the resin molded product, the molding die, and the method for manufacturing the resin molded product described above are not limited to the above-described embodiments, and can be arbitrarily changed in design within the scope of the claims. . Details will be described below.

A first edge that is in contact with the second surface of the section, a second edge that is a bottom edge of the recess, and an inclined surface that is inclined away from the section from the first edge to the second edge Alternatively, the design can be arbitrarily changed as long as it has a curved surface. There may be at least one recess. The length dimension of the recess can be substantially the same as the dimension in the length direction of the recess of the section. Moreover, the length dimension of a recessed part can be made longer than the dimension of the length direction of the said recessed part of an intercept part, and can also be shortened. Also. The first edge can be an edge on the opening side (one side in the third direction Z) of the concave portion of the curved surface. The second edge can be an edge on the bottom side of the concave portion of the curved surface (the other side in the third direction Z). The recess 140 can be omitted.

  In the above embodiment, the side wall 120 has an annular shape standing on the peripheral edge of the base 110. However, the side wall can be arbitrarily changed in design as long as it is erected on the base and has a wall surface. For example, the design of the side wall can be changed to a shape such as a substantially rectangular shape in plan view, a substantially arc shape in plan view, or a substantially U shape in plan view. Also in this case, the space can be partitioned by the side wall and the base. The space is an arbitrary space. The accommodation space S can also be used as an arbitrary space.

  In the above embodiment, the terminal 200a has the terminal body 210a, the sections 220a, 230a, and 240a, and the connection parts 250a and 260a.

  In the above embodiment, the section 220 a is embedded in the side wall 120 so that the first surface 221 a is partially exposed from the wall surface 121 of the side wall 120. However, the section has a first surface and a second surface opposite to the first surface, the first surface is exposed from the wall surface of the side wall, and the second surface is in contact with the first edge of the recess of the side wall. The design can be arbitrarily changed as long as it is embedded in the side wall. For example, the section may be configured to be embedded in the side wall so that the entire area of the first surface is exposed from the wall surface of the side wall. In this regard, the design of the intercept sections 230a and 240a can be changed in the same manner. The terminals 200b and 200c can be omitted.

  In the above-described embodiment, the tip portions of the connection portions 250a and 260a of the terminal 200a protrude from the outer surface of the base 110. However, the connecting portion can be configured to protrude from the second surface of the body. Further, in the case where connecting means such as a pin or a cable is connected to the terminal connecting portion within the body, the terminal connecting portion can be configured not to protrude from the body. The design of the terminals 200b and 200c can be similarly changed.

  The seal part 300 can be omitted. In the above embodiment, the seal portion 300 has the center portion 310 filled in the center portion 141 of the recess 140 and the plurality of branch portions 320 filled in the branch portions 142 of the recess 140. However, the design of the seal portion can be arbitrarily changed as long as it is filled in the concave portion of the second surface of the body and is fixed to the portion exposed from the concave portion of the body and the terminal. That is, the design of the seal portion can be arbitrarily changed in accordance with the shape of the recess on the second surface of the body.

  In the said Example, the 1st metal mold | die 10 assumed that it had the convex part 11, the recessed part 12, protrusion 13a, 13b, 13c, and the sprue 14. FIG. However, the first mold has a convex portion that can abut on the first surface of the terminal section of the terminal, and a projection that is provided at an interval from the convex portion, and the projection is a base of the projection. A first edge that is a side edge and is capable of contacting a second surface opposite to the first surface of the section, a second edge that is a leading edge of the protrusion, and the first edge The design can be arbitrarily changed as long as it has an inclined surface or a curved surface that is inclined so as to be separated from the convex portion toward the second edge. For example, the first mold may be configured to have a recess, a protrusion provided in the recess, and a protrusion provided in the recess and spaced from the protrusion. It is. The first edge can be an edge on the opening side (one side in the third direction Z) of the protrusion on the curved surface. The second edge can be an edge on the bottom side of the projection on the curved surface (the other side in the third direction Z).

  In the above embodiment, the protrusions 13a, 13b, and 13c are pulsations, but the present invention is not limited to this. That is, the projection of the first mold in the present specification is a concept including both a convex portion and a long ridge. The length dimension of the projection can be made substantially the same as the dimension of the section portion in the length direction of the projection. Further, the length dimension of the projection can be made longer or shorter than the dimension of the section portion in the length direction of the projection. Note that at least one protrusion may be provided.

  In the above embodiment, the second mold 20 has the recess 21 and the protrusion 22. However, the design of the second mold can be arbitrarily changed as long as it can form a cavity capable of accommodating at least the terminal section of the terminal together with the first mold when combined with the first mold. .

  In the method of manufacturing a resin molded product described above, the segment part of at least one terminal is inserted between the convex part and the protrusion of the first mold, the first surface of the segment part is the convex part, and the second surface is By contacting the first edge of the protrusion, the section is sandwiched between the convex portion and the first edge, and in this state, the first and second molds are clamped, and at least the section of the terminal Can be arbitrarily changed as long as it is placed in the cavities of the first and second molds, an insulating resin is injected into the cavities, cured, and the section is embedded in the insulating resin.

It is assumed that the first mold 10 is sandwiched between the protrusion 11 and the second mold 20 protrusion 22. However, when the first and second molds are clamped, the design can be arbitrarily changed as long as at least the terminal sections of the terminals are arranged in the cavities of the first and second molds. Further, the terminal section of the terminal is sandwiched between the convex portion of the first mold and the first edge of the projection, while the terminal body of the terminal is partially or entirely sandwiched between the first and second molds. It is possible to make it. Further, the terminal body of the terminal is hollowly disposed in the cavities of the first and second molds by sandwiching the section of the terminal between the convex part of the first mold and the first edge of the protrusion.

In the case of such a molding die, since the terminal section is bent with respect to the terminal body , it is easily affected by the injection pressure when the insulating resin is injected into the cavity. However, since the intercept portion is sandwiched between the convex portion and the first edge of the protrusion, it is possible to suppress the intercept portion from being moved or deformed by the injection pressure.

In the case of the manufacturing method of such an aspect, the terminal section is bent with respect to the terminal main body , and thus is easily affected by the injection pressure when the insulating resin is injected into the cavity. However, since the intercept portion is sandwiched between the convex portion and the first edge of the protrusion, it is possible to suppress the intercept portion from being moved or deformed by the injection pressure.

Thereafter, the body 100 and the terminals 200a, 200b, and 200c are accommodated in the cavity C2 of the third and fourth molds 30 and 40, and the recess 140 of the body 100 is closed with the fourth mold 40. Thereby, a space is defined by the fourth mold 40 and the concave portion 140 of the body 100. Thereafter, the second insulating resin R2 is injected from the sprue 42 into the space to fill the space (concave portion 140). Thereafter, the second insulating resin R2 is cured. In this way, the second insulating resin R2 is molded as the seal portion 300. Thereby, the seal part 300 is fixed to the body 100 and the terminals 200a, 200b, and 200c. Thereafter, the third and fourth molds 30 and 40 are released, and the body 100, the terminals 200a, 200b, and 200c, and the seal portion 300 are taken out. A resin molded product is manufactured as described above.

In the above embodiment, the body 100 has the base 110, the side wall 120, the concave portions 130a, 130b, and 130c, the concave portion 140, and the convex portion 150. However, the body has a base, a side wall standing on the base and having a wall surface, and a concave portion provided on the side wall, and the concave portion is an edge on the opening side of the concave portion. A first edge that is in contact with the second surface of the section, a second edge that is a bottom edge of the recess, and an inclined surface that is inclined away from the section from the first edge to the second edge Alternatively, the design can be arbitrarily changed as long as it has a curved surface. There may be at least one recess. The length dimension of the concave portion can be substantially the same as the dimension in the length direction of the section portion . Further, the length of the concave portion can be made longer or shorter than the length of the section in the length direction. Also. The first edge can be an edge on the opening side (one side in the third direction Z) of the concave portion of the curved surface. The second edge can be an edge on the bottom side of the concave portion of the curved surface (the other side in the third direction Z). The recess 140 can be omitted.

In the above embodiment, the protrusions 13a, 13b, and 13c are pulsations, but the present invention is not limited to this. That is, the projection of the first mold in the present specification is a concept including both a convex portion and a long ridge. The length dimension of the projection can be made substantially the same as the dimension of the section portion in the length direction of the projection. Further, the length dimension of the protrusion can be made longer than the dimension in the length direction of the section , and can be made shorter. Note that at least one protrusion may be provided.
