[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, when the electronic component unit of the above type is actually mounted on a vehicle or the like, depending on the possibility of water immersion, there are cases where an electronic component unit having a structure with a reliable waterproof treatment and an electronic component unit having a structure with a simple waterproof structure are used in distinction with the place where the electronic component unit is mounted. It is required to manufacture such electronic component units corresponding to a plurality of specifications without impairing the original performance as an electronic component unit while reducing the production cost as much as possible.

[0008] An object of the present application is to provide a manufacturing method of an electronic component unit and an electronic component unit capable of manufacturing electronic component units corresponding to a plurality of specifications at a low cost.

[0009] TECHNICAL SOLUTION FOR SOLVING THE PROBLEMS

[0010] In order to achieve the above object, the manufacturing method of an electronic component unit and the electronic component unit of the present application are characterized by the following.

[0011] A manufacturing method of an electronic component unit built with an electronic component, wherein

[0012] The electronic component unit has:

[0013] a base member having the electronic component, a pair of terminals connected to the electronic component and extending in a prescribed direction, and a housing body internally embedding to accommodate the electronic component and externally having engaging portions protruding or recessed in a direction intersecting the prescribed direction to respectively expose the pair of terminals to the outside;

[0014] a housing assembled to the base member to accommodate the pair of terminals to be isolated from each other,

[0015] The manufacturing method includes:

[0016] a first step of manufacturing the base member;

[0017] a second step of selecting one of a connector-type housing having a connector shape and a case-type housing having a case shape as the housing, the connector-type housing being integrally additionally formed to the base member and having a fitting opening exposing one end of the pair of terminals, the case-type housing being assembled to the base member in a manner of being engaged with the base member and having a pair of accommodation chambers accommodating the pair of terminals so as to be isolated from each other, and assembling the selected housing to the base member.

[0018] In the second step,

[0019] in a case where the connector-type housing is selected, the connector-type housing is integrally additionally formed to the base member in a manner of burying the engagement portion of the accommodation body of the base member and exposing the one end to the fitting opening,

[0020] in a case where the case-type housing is selected, after connecting a pair of electric wires to the pair of terminals, the case-type housing is assembled to the base member in a manner of being engaged with the engagement portion of the accommodation body of the base member, and accommodating the pair of terminals in the pair of accommodation chambers and inserting the pair of electric wires through the inside and outside of each of the pair of accommodation chambers.

[0021] An electronic component unit includes:

[0022] a base member having an electronic component, a pair of terminals connected to the electronic component and extending in a prescribed direction, and an accommodation body burying the electronic component inside and having an engagement portion exposing the pair of terminals to the outside and protruding or recessing in a direction intersecting the prescribed direction on an outer surface;

[0023] a housing integrally formed to the base member, burying the engagement portion of the accommodation body of the base member, and having a fitting opening exposing one end of the pair of terminals.

[0024] Effects of the Invention

[0025] According to the manufacturing method of the electronic component unit of the present application, the base member part can be used as a general-purpose part regardless of whether the connector-type housing or the case-type housing is selected. In the case where the connector-type housing is selected, by integrally adding the connector-type housing to the base member part by burying the engaging portion of the housing of the base member part, the pair of terminals of the base member part can be properly insulated, and the connector-type housing and the base member part can be firmly integrated. Thus, for example, even in the case where an external force such as rotation of one of the base member part and the connector-type housing acts on the connector-type housing, the connector-type housing and the base member part can be prevented from being separated. On the other hand, in the case where the case-type housing is selected, by assembling the case-type housing to the base member part by engaging the engaging portion of the base member part with the housing of the base member part, and by housing the pair of terminals in the pair of housing chambers, the pair of terminals of the base member part can be properly insulated, and the base member part can hold the case-type housing with sufficient strength. Thus, for example, as in the above, the case-type housing and the base member part can be prevented from being separated. Therefore, according to the manufacturing method of the electronic component unit of the present application, by using the base member part as a general-purpose part, the electronic component units corresponding to a plurality of specifications can be manufactured at low cost by changing the housing according to the specification.

[0026] In addition, according to the electronic component unit of the present application (the electronic component unit using the connector-type housing), by integrally forming the housing to the base member part by burying the engaging portion of the housing of the base member part, the pair of terminals of the base member part can be properly insulated, and the housing and the base member part can be firmly integrated. Thus, for example, even in the case where an external force such as rotation of one of the base member part and the housing acts on the housing, the housing and the base member part can be prevented from being separated. Therefore, the electronic component unit of the present application is excellent in durability.

[0027] The present application has been described above with a certain degree of generalization. In addition, the details of the present application will be further clarified by reading the following description of the mode for carrying out the application with reference to the accompanying drawings.

[0040] <EMBODIMENT>

[0041] Hereinafter, an electronic component unit 1 of an embodiment of the present application, and a manufacturing method of the electronic component unit 1 will be described with reference to the drawings. The electronic component unit 1 of the embodiment of the present application (refer to FIG. 1) is an electronic component unit in which a base member 10 is provided with a pair of terminals 20, 20, and a groove portion 30 is formed between the pair of terminals 20, 20. Figure 5 or Figure 10 ​​​​​For example, it can be used as a temperature sensor when the base component 2, described later, is inserted and fixed into the mounting hole (not shown) of the mounting object. The mounting object is, for example, the wall of a container storing vehicle transmission oil or engine oil, in which case the electronic component unit 1 installed on the mounting object functions to measure the temperature of the oil in the container.

[0042] like Figure 5 or Figure 10 As shown, the electronic component unit 1 consists of a base component 2 and a housing 3 assembled on the base component 2. As the housing 3, a... Figure 5 The connector type housing 3A shown, and Figure 10 Any one of the shell-type housings 3B shown is assembled onto the base component 2. That is, whether the connector-type housing 3A or the shell-type housing 3B is selected, the base component 2 is used as a general-purpose part to form the electronic component unit 1.

[0043] For ease of explanation, the following is as follows: Figure 1 "Front," "rear," "left," "right," "up," and "down" are defined as shown. The "front-rear direction," "left-right direction," and "up-down direction" are orthogonal to each other. The up-down direction corresponds to the "prescribed direction" of this invention. The front-rear direction, left-right direction, and up-down direction do not necessarily need to be consistent with the front-rear direction, left-right direction, and up-down direction of the vehicle, etc., equipped with the electronic component unit 1.

[0044] First, the structure of base component 2, which is used as a general-purpose part, will be explained. For example... Figures 1-3 As shown, the base component 2 has electronic components 10 (see reference). Figure 3 The device includes a housing 20 that houses the electronic component 10 and a pair of terminals 30 that are connected to the electronic component 10 and exposed to the outside of the housing 20. Specifically, the electronic component 10 is a thermistor element. The electronic component 10 and the pair of terminals 30 are integrated with the resin housing 20 by means of transfer molding or the like, in a manner that allows them to be stored (embedded) inside the housing 20.

[0045] like Figure 1 and Figure 2 As shown, the resin molded body 20 integrally comprises a cylindrical main body 21 extending vertically, a protrusion 22 protruding downward from the lower surface of the main body 21, and a protrusion 23 protruding upward from the upper surface of the main body 21. An annular groove 24 is formed on the outer peripheral surface of the main body 21, and a rubber O-ring 40 is fitted into the annular groove 24. The O-ring 40 fitted into the annular groove 24 seals tightly against the inner peripheral wall of the mounting hole of the object to be mounted, thus providing a waterproof function. For example, from... Figure 3It is understood that the protrusion 22 has an elongated, hole-like shape that is longer in the left-right direction, protruding downwards from the main body 21, and the electronic component 10 is embedded in the protrusion 22. For example... Figure 1 and Figure 2 As shown, the protrusion 23 has a first portion 25 that protrudes upward from the upper surface of the main body 21 and extends in the left-right direction, and a pair of second portions 26 that protrude from the entire left-right region of the upper end of the first portion 25 toward both sides in the front-rear direction, having a generally T-shaped shape when viewed from the left-right direction. A groove 27 that extends through in the front-rear direction is formed at the center of the upper surface of the protrusion 23 in the left-right direction. Here, the protrusion 23 corresponds to the "engaging portion" of the present invention, and the groove 27 corresponds to the "recess" of the present invention.

[0046] As from Figure 1 , Figure 2 and Figure 6 As can be understood, a pair of terminals 30 each have a shape extending in a generally straight line in the vertical direction, and are arranged at intervals in the horizontal direction. The portion extending in the vertical direction below the exposed portion 31, which is the upper region, is embedded throughout the protrusion 23, the main body 21, and the projection 22 of the housing 20. The lower ends of the pair of terminals 30 located in the projection 22 are connected to the electronic component 10 (see reference). Figure 3 and Figure 6 The exposed portions 31 of a pair of terminals 30 protrude in a straight line upward from the left and right sides of the groove 27 on the upper end face of the protrusion 23, and are exposed to the outside of the receiver 20. The structure of the base component 2, which is used as a general-purpose part, has been described above.

[0047] Next, select connector type housing 3A (refer to...) Figure 5 The manufacturing sequence of the electronic component unit 1, which is assembled into the housing 3 of the base component 2 used as a general-purpose component, will be described.

[0048] First, prepare and manufacture parts for use as general-purpose components. Figure 1 The base component 2 is shown. Next, in order to prepare for the assembly of the connector-type housing 3A, as shown... Figure 4 As shown, for Figure 1 The base component 2 shown is subjected to a process in which the exposed portions 31 of each of a pair of terminals 30 are bent into an L-shape. Through this process, the exposed portions 31 of the pair of terminals 30, which are spaced apart in the left-right direction, are respectively composed of a first portion 32 extending linearly upward from the housing 20, and a second portion 33 extending linearly rearward from the upper end of the first portion 32. Hereinafter, for ease of explanation, Figure 4 The base component 2 shown is referred to as "base component 2A".

[0049] Next, as shown in Figure 5 and Figure 6 a resin-made connector-type housing 3A is integrally added and formed to the base member 2A. Specifically, the base member 2A is integrated with the connector-type housing 3A by insert molding or the like. The connector-type housing 3A integrally added and formed to the base member 2A integrally includes a main body 80 integrated with the base member 2A and having a shape extending upward from the base member 2A, and a cap-shaped connector portion 90 having a substantially rectangular box shape and extending in a manner of protruding rearward from an upper portion of the main body 80. A rear end of the connector portion 90 is open, constituting a fitting opening 91.

[0050] As shown in Figure 6 , the first portions 32 of the pair of terminals 30 of the base member 2A are embedded in the entirety of the main body 80. The second portions 33 of the pair of terminals 30 protrude toward the rear from a depth wall (front end wall) of the hollow portion of the cap-shaped connector portion 90. The second portions 33 of the pair of terminals 30 located in the hollow portion of the connector portion 90 are exposed to the outside via the fitting opening 91 of the connector portion 90.

[0051] As shown in Figure 6 , the main body 80 integrated with the base member 2A is shaped so as to fill in the concave-convex structure constituted by the outer shape of the entirety of the protruding portion 23 of the base member 2A. Specifically, a portion 81 of the main body 80 enters the inside of the front and rear pair of groove portions 28 (recessed portions recessed inward in the front and rear directions and extending in the left and right directions) constituting the left and right sides adjacent to the lower sides of the front and rear pair of second portions 26 of the protruding portion 23 without a gap. Thereby, the main body 80 (i.e., the connector-type housing 3A) and the base member 2A can be firmly integrated. For example, even in a case where a stress in a rotational direction of the pair of terminals 30 extending in the up and down directions is applied to the connector-type housing 3A after the base member 2A is fixed, the connector-type housing 3A can be inhibited from separating from the base member 2A. In addition, the main body 80 (i.e., the connector-type housing 3A) can be prevented from falling upward from the base member 2A.

[0052] As shown in Figure 7 , the main body 80 integrated with the base member 2A is shaped so as to fill in the groove portion 27 of the base member 2A (protruding portion 23) located between the pair of terminals 30. Specifically, a portion 82 of the main body 80 enters the inside of the groove portion 27 of the protruding portion 23 without a gap. Thereby, the pair of terminals 30 of the base member 2A can be appropriately insulated between the pair of terminals 30, and the along-surface distance between the pair of terminals 30 can be lengthened, insulating the pair of terminals 30 more reliably. As above, the assembly of the electronic component unit 1 is completed, obtaining the electronic component unit 1 shown in Figure 5 .

[0053] In Figure 5The connector section 90 of the electronic component unit 1 shown engages with a counterpart connector (not shown) via a mating port 91. This counterpart connector is located at the end of a wire extending from the temperature sensing device (not shown). By connecting the connector section 90 to the counterpart connector, an electrical signal (indicating the temperature around the thermistor element) output from the electronic component 10 (thermometer element) is input to the temperature sensing device, enabling the detection of the temperature around the thermistor element. The manufacturing sequence of the electronic component unit 1 when selecting the connector-type housing 3A has been explained above.

[0054] Next, select the shell type 3B (refer to...) Figure 10 The manufacturing sequence of the electronic component unit 1 when it is assembled into the housing 3 of the base component 2, which is used as a general component, will be described.

[0055] First, prepare and manufacture parts for use as general-purpose components. Figure 1 The base component 2 is shown. Next, in order to prepare for the assembly of the shell-type outer casing 3B, as follows... Figure 8 As shown, for Figure 1 The base component 2 shown is subjected to a process in which the upper part of the exposed portion 31 of each of the pair of terminals 30 is cut off and one end of the lead 6 is connected to the remaining exposed portion 31. Specifically, one end of each of the pair of leads 6 is connected to the exposed portion 31 of each of the pair of terminals 30 by welding. The pair of leads 6 extend upward from the exposed portion 31 of the pair of terminals 30. Each of the pair of leads 6 has flexibility that allows it to be bent arbitrarily. Hereinafter, for ease of explanation, Figure 8 The base component 2 shown is referred to as "base component 2B".

[0056] Next, prepare and manufacture the shell 4 and cover 5 that constitute the shell-type outer casing 3B (see reference). Figure 9 It should be noted that the housing 4 and the cover 5 can also be manufactured and prepared before the above-described "process of connecting the lead 6 to the exposed portion 31 of the terminal 30". The housing 4 and the cover 5 are manufactured by resin molding. The housing 4 is a component assembled to the base component 2B, and the cover 5 is a component assembled to the housing 4, wherein the housing 4 is in the state of being assembled to the base component 2B. The structure of the housing 4 and the cover 5 will be described in turn below.

[0057] First, the structure of shell 4 will be explained. For example... Figures 9-11 As shown, the housing 4 integrally comprises a generally rectangular box-shaped main body 51 with an opening at the top, an elongated portion 52 that protrudes downward from the center of the bottom wall of the main body 51 in the front-rear direction and extends in the left-right direction, and a cylindrical portion 53 that is continuous with the lower part of the elongated portion 52 and extends in the vertical direction. The outer diameter of the cylindrical portion 53 is approximately the same as the outer diameter of the main body 21 of the base component 2B (see reference). Figure 10 andFigure 11 ).

[0058] On the housing 4, in the front-rear direction central portion of the elongated portion 52 and the cylindrical portion 53, a slit portion 54 extending in the left-right direction from the right end of the elongated portion 52 and the cylindrical portion 53 to the vicinity of the left end is formed throughout the entire region in the up-down direction (refer to Figure 9 and Figure 11 ). The slit portion 54 opens to the right at the right end of the elongated portion 52 and the cylindrical portion 53, opens to the upper side at the upper surface of the elongated portion 52 (i.e., the bottom surface of the main body portion 51), and opens to the lower side at the lower surface of the cylindrical portion 53. In addition, on the housing 4, in the front-rear direction central portion of the right side wall of the substantially rectangular flat plate shape of the main body portion 51 and the right end portion of the elongated portion 52, a slit portion 55 extending throughout the main body portion 51 and the elongated portion 52 in the up-down direction is formed (refer to Figure 9 and Figure 10 ). The slit portion 55 opens at each of the upper surface of the right side wall of the main body portion 51 and the lower surface of the elongated portion 52, and each of the inner and outer surfaces (left and right end surfaces) of the right side wall of the main body portion 51. The lower end portion of the slit portion 55 overlaps with the right end portion of the slit portion 54. By the slit portion 54 and the slit portion 55 being formed on the housing 4, the housing 4 has a shape that is easily deformed in such a manner that the slit portion 54 and the slit portion 55 widen. When the housing 4 is assembled to the base member 2B, the first portion 25 of the protrusion portion 23 and the exposed portions 31 of the pair of terminals 30 of the base member 2B are accommodated in the slit portion 54 (refer to Figure 11 ), and the exposed portions 31 of the pair of terminals 30 and the pair of lead wires 6 pass through the slit portion 55 (refer to Figure 11 ). When the cover 5 is assembled to the housing 4, the protruding portions 72 described later on the rear surface of the cover 5 are accommodated in the slit portion 55 (refer to Figure 10 ).

[0059] On the inner walls on both sides in the front-rear direction of the slit portion 54 of the cylindrical portion 53, a pair of groove portions 56 recessed to the outside in the front-rear direction and extending in the left-right direction are formed in correspondence with a pair of second portions 26 of the protrusion portion 23 of the base member 2B on both sides in the front-rear direction (refer to Figure 9 and Figure 11 ). When the housing 4 is assembled to the base member 2B, the pair of second portions 26 of the protrusion portion 23 of the base member 2B are accommodated in the pair of groove portions 56.

[0060] On the inner walls on both sides in the front-rear direction of the slit portion 55 of the right side wall of the main body portion 51, a pair of groove portions 61 recessed to the outside in the front-rear direction and extending in the up-down direction from the upper end of the right side wall to the midway position in the up-down direction are formed (refer to Figure 9 ). When the cover 5 is assembled to the housing 4, the pair of protruding portions 73 described later on the rear surface of the cover 5 are accommodated in the pair of groove portions 61.

[0061] On the upper edge portion of the rear side wall of the substantially rectangular flat plate shape of the main body portion 51 extending in the left-right direction, a recessed portion 62 recessed downward in the left-right direction pair is formed corresponding to the left-right pair of lead wires 6 extending from the exposed portions 31 of the left-right pair of terminals 30. When the case 4 is assembled to the base member 2B, the left-right pair of lead wires 6 are inserted through the left-right pair of recessed portions 62 (refer to Figure 10 and Figure 11 ). The width (interval in the left-right direction) of each of the left-right pair of recessed portions 62 is slightly smaller than the outer diameter of the lead wire 6. That is, the lead wire 6 is pressed into the recessed portion 62.

[0062] On the upper edge portion of each of the front side wall and the rear side wall of the substantially rectangular flat plate shape of the main body portion 51, an inclined surface (plane) 63 inclined toward the outside in the front-rear direction is formed (refer to Figure 9 and Figure 11 ). When the cover 5 is assembled to the case 4, the front-rear pair of inclined surfaces 77 on the rear face of the cover 5 come into surface contact with the front-rear pair of inclined surfaces 63 (refer to Figure 9 and Figure 11 ). On the outer face of the left side wall of the substantially rectangular flat plate shape of the main body portion 51, a locking protrusion (omitted from the drawing) is formed. When the cover 5 is assembled to the case 4, the edge of the locking hole of the locking frame portion 76 (refer to Figure 9 ) on the rear face of the cover comes into engagement with the locking protrusion.

[0063] Next, the structure of the cover 5 will be described. As shown in Figures 9-11 , the cover 5 is provided with a top plate portion 71 having a rectangular flat plate shape corresponding to the shape of the opening at the upper end of the case 4 (the main body portion 51). On the front-rear direction central portion of the right end edge portion of the top plate portion 71 extending in the front-rear direction, a substantially elongated flat plate-shaped protruding portion 72 is provided corresponding to the slit portion 55 of the case 4, the protruding portion 72 being provided so as to extend downward. On the front-rear side faces of the protruding portion 72, a front-rear pair of protruding portions 73 projecting toward the outside in the front-rear direction and extending in the up-down direction are provided. On the left-right direction central portion and the front-rear direction central portion of the top plate portion 71, a substantially elongated flat plate-shaped protruding portion 74 is provided, the protruding portion 74 being provided so as to extend downward. When the cover 5 is assembled to the case 4, the front end (lower end) 74a of the protruding portion 74 enters the groove portion 27 of the protruding portion 23 of the base member 2B and comes into abutment with the bottom wall of the groove portion 27 (refer to Figure 12 ). Here, the protruding portion 74 corresponds to the "partition wall" of the present application.

[0064] On the rear end edge portion of the top plate portion 71 extending in the left-right direction, a left-right pair of protruding portions 75 is formed corresponding to the left-right pair of recessed portions 62 of the case 4, the left-right pair of protruding portions 75 being formed so as to project downward (refer to Figure 11). On the left end edge portion of the top plate portion 71, a locking frame portion 76 having a locking hole is provided corresponding to the above-mentioned locking protrusion of the case 4, and the locking frame portion 76 is provided so as to extend downward (refer to Figure 9 ). On the lower surface of the top plate portion 71, inclined surfaces (flat surfaces) 77 inclined toward the inside in the front-rear direction are respectively formed on the front end edge portion and the rear end edge portion extending in the left-right direction, corresponding to the front-rear pair of inclined surfaces 63 of the case 4 (refer to Figure 9 and Figure 11 ). The structure of the case 4 and the cover 5 has been described above.

[0065] Next, the case 4 is assembled to the base member 2B from the left side. Specifically, the case 4 is assembled to the base member 2B from a state in which the case 4 is disposed on the left side of the base member 2B (refer to Figure 9 ) so that the exposed portions 31 of the pair of terminals 30 and the pair of lead wires 6 pass through the slit portions 55, and the first portions 25 of the protrusion portions 23 and the exposed portions 31 of the pair of terminals 30 are accommodated in the slit portions 54, and the front-rear pair of second portions 26 of the protrusion portions 23 are accommodated in the front-rear pair of groove portions 56 (refer to Figure 11 ).

[0066] In a state in which the assembly of the case 4 to the base member 2B is completed, the front-rear pair of second portions 26 of the protrusion portions 23 of the base member 2B are engaged with the front-rear pair of groove portions 56 of the case 4. That is, the front-rear pair of groove portions 56 of the case 4 are engaged with the concave-convex structure constituted by the outer shape of the protrusion portions 23 of the base member 2B as a whole. Thereby, the case 4 (i.e., the case-type housing 3B) and the base member 2B can be firmly integrated. For example, even in a case in which the base member 2B is fixed, and a stress in a rotational direction of the up-down direction in which the pair of terminals 30 extends is applied to the case 4 (i.e., the case-type housing 3B), the case 4 (i.e., the case-type housing 3B) and the base member 2B can be inhibited from being separated. Further, the case 4 (i.e., the case-type housing 3B) is prevented from falling upward from the base member 2B. The slit portions 54 of the case 4 are plugged by the first portions 25 of the protrusion portions 23 accommodated in the slit portions 54 (refer to Figure 11 ). The exposed portions 31 of the pair of terminals 30 of the base member 2B are surrounded by the side wall portions of the main body portion 51 of the case 4 (refer to Figure 11 ). The pair of lead wires 6 extending upward from the exposed portions 31 of the pair of terminals 30 are bent toward the rear at the root portions. A portion of the extension direction of the pair of lead wires 6 extending toward the rear along the front-rear direction from the bent portions is respectively pressed into the pair of recesses 62 of the case 4 (refer to Figure 10 and Figure 11 ).

[0067] Next, the cover 5 is assembled to the case 4 from the upper side. Specifically, the cover 5 is assembled to the case 4 from a state in which the cover 5 is disposed on the upper side of the case 4 (refer to Figure 9) to the housing 4 so that the top plate portion 71 blocks the upper end opening of the main body portion 51, and the protruding portion 72 is accommodated in the slit portion 55 (refer to Figure 10 ), and the front and rear pair of protruding portions 73 are accommodated in the front and rear pair of groove portions 61, and the protruding portion 74 enters between the exposed portions 31 of the left and right pair of terminals 30 to isolate the left and right pair of exposed portions 31 in the left and right directions (refer to Figure 12 ), and the front end (lower end) 74a of the protruding portion 74 enters the groove portion 27 of the protruding portion 23 of the base member 2 and abuts against the bottom wall of the groove portion 27 (refer to Figure 12 ), and the rim of the locking hole of the locking frame portion 76 engages with the locking protrusion.

[0068] In the assembled state of the cover 5 to the housing 4, the top plate portion 71 blocks the upper end opening of the main body portion 51. By the engagement of the rim of the locking hole of the locking frame portion 76 with the locking protrusion, the cover 5 is prevented from falling upward from the housing 4. The front end portion of the protruding portion 72 contacts (engages with) the right end surface 23a (refer to Figure 9 ) of the protruding portion 23 of the base member 2B. Further, the front and rear pair of protruding portions 73 are accommodated in the front and rear pair of groove portions 61. Thereby, the cover 5 is prevented from falling leftward from the housing 4. The slit portion 55 of the housing 4 is blocked by the protruding portion 72 accommodated in the slit portion 55. Since the protruding portion 74 divides the hollow portion of the main body portion 51 in half in the left and right directions, a left and right pair of accommodation chambers 78 (refer to Figure 11 and Figure 12 ) are formed inside the main body portion 51. The exposed portions 31 of the pair of terminals 30 are accommodated in each of the pair of accommodation chambers 78, respectively. Thereby, the exposed portions 31 of the pair of terminals 30 are accommodated isolated from each other. The front end (lower end) 74a of the protruding portion 74 is pressed flat by the bottom wall of the groove portion 27 of the protruding portion 23 of the base member 2B (refer to Figure 12 ). Thereby, the pair of terminals 30 of the base member 2B can be properly insulated therebetween, and the face distance between the pair of terminals 30 is lengthened to more reliably insulate the pair of terminals 30 from each other. The pair of lead wires 6 extending from the exposed portions 31 of the pair of terminals 30 extend from each of the pair of accommodation chambers 78 toward the rear and outward of the electronic component unit 1 via the recessed portions 62. The left and right pair of protruding portions 75 of the cover 5 press the lead wires 6 accommodated in the left and right pair of recessed portions 62 of the housing 4 from the upper side (refer to Figure 11 ). Thereby, even if an external force acts on the lead wires 6 extending outward from the electronic component unit 1, the external force can be suppressed from acting on the junctions of the lead wires 6 and the terminals 30 (exposed portions 31). The front and rear pair of inclined surfaces 77 of the cover 5 contact the front and rear pair of inclined surfaces 63 of the housing 4, respectively. Thereby, by the engagement of the inclined surfaces 77 and 63, the housing 4 is suppressed from deforming in a manner that the slit portions 54 and 55 widen. As described above, the assembly of the electronic component unit 1 is completed, and Figure 10The electronic component unit 1 shown.

[0069] From Figure 10 The pair of lead wires 6 extending from the electronic component unit 1 shown (refer to Figure 1 ) are electrically connected to electric wires extending from a temperature detecting device (omitted from the drawing). Thereby, an electric signal (a signal indicating the temperature of the periphery of the thermistor element) output from the electronic component 10 (the thermistor element) is input to the temperature detecting device, and the temperature of the periphery of the thermistor element can be detected. The above describes the manufacturing sequence of the electronic component unit 1 in the case of selecting the housing type case 3B.

[0070] <Effects>

[0071] The above, according to the manufacturing method of the electronic component unit 1 of the present embodiment, whether in the case of selecting the connector type case 3A, or in the case of selecting the housing type case 3B, the base member 2 can be used as a general-purpose part. In the case of selecting the connector type case 3A, by integrally adding forming the connector type case 3A to the base member 2 in a manner of filling the engaging portion (the protruding portion 23) possessed by the accommodating body 20 of the base member 2, the pair of terminals 30 of the base member 2 can be appropriately insulated, and the connector type case 3A and the base member 2 can be firmly integrated. For example, even in the case where a stress in a rotational direction with the pair of terminals 30 extending as a rotational axis is applied to the connector type case 3A while the base member 2 is fixed, the connector type case 3A and the base member 2 can be inhibited from separating. In the case of selecting the housing type case 3B, by assembling the housing type case 3B to the base member 2 in a manner of engaging with the engaging portion 23 possessed by the accommodating body 20 of the base member 2, and accommodating the pair of terminals 30 in the pair of accommodating chambers 78, the pair of terminals 30 of the base member 2 can be appropriately insulated, and the housing type case 3B and the base member 2 can be firmly integrated. For example, as above, even in the case where a stress in a rotational direction is applied to the housing type case 3B, the housing type case 3B and the base member 2 can be inhibited from separating. Therefore, according to the manufacturing method of the electronic component unit 1 of the present embodiment, the electronic component unit 1 can be manufactured using a general-purpose part that can correspond to a plurality of specifications.

[0072] Further, according to the manufacturing method of the electronic component unit 1 of the present embodiment, by filling the recessed portion (the groove portion 27) possessed by the accommodating body 20 of the base member 2 with the connector type case 3A, or by inserting the partition wall (the extending portion 74) of the housing type case 3B to the recessed portion 27, the face distance between the pair of terminals 30 can be lengthened, and the pair of terminals 30 can be more reliably insulated.

[0073] Further, according to the electronic component unit 1 of the present embodiment (refer to Figure 5), the housing 3 (connector-type housing 3A) is integrally formed to the base member 2 in a manner that the receiving body 20 of the base member 2 has the engaging portion 23, the pair of terminals 30 of the base member 2 can be properly insulated, and the housing 3 and the base member 2 can be firmly integrated. For example, even in a case where a stress in a rotational direction of the base member 2 with the pair of terminals 30 extending in a prescribed direction as a rotational axis is applied to the housing 3, the housing 3 and the base member 2 can be prevented from being separated. Thus, according to the electronic component unit 1 of the present embodiment (refer to Figure 5 ), a general-purpose component that can correspond to a plurality of specifications can be used to manufacture the electronic component unit 1.

[0074] Further, according to the electronic component unit 1 of the present embodiment (refer to Figure 5 ), by filling the recessed portion 27 of the receiving body 20 of the base member 2 with the housing 3 (connector-type housing 3A), the face distance between the pair of terminals 30 can be extended, and the pair of terminals 30 can be more reliably insulated.

[0075] <Other Modes>

[0076] Note that the present application is not limited to the above-described embodiments, and various modifications can be made within the scope of the present application. For example, the present application is not limited to the above-described embodiments, and can be appropriately modified, improved, or the like. In addition, the material, shape, size, number, arrangement position, and the like of each component in the above-described embodiments are arbitrary as long as the present application can be achieved, and are not limited.

[0077] For example, in the electronic component unit 1 (refer to Figure 10 ) of the above-described embodiment in which the housing-type housing 3B is assembled, the contact of the terminal 30 extending from the base member 2 and the lead 6, and the lead 6 extending from the terminal 30 are not buried in the sealing body such as the potting resin inside the housing 4 (main body portion 51) (refer to Figure 11 ). In contrast, a hole (through-hole) can be formed in the top plate portion 71 of the cover 5. By forming the hole, the potting material can flow into the inside of the housing 4 (main body portion 51) and be cured through the hole. Thus, inside the housing 4 (main body portion 51), by burying the contact of the terminal 30 extending from the base member 2B and the lead 6, and the lead 6 extending from the terminal 30 in the sealing body such as the potting resin, further insulation between the terminals and the contacts can be achieved.

[0078] Here, the features of the above-described manufacturing method of the electronic component unit 1 of the present application and the embodiments of the electronic component unit 1 are simply summarized and listed in the following [1] to [4], respectively.

[0079] [1] A manufacturing method of an electronic component unit (1) in which an electronic component (10) is built in, wherein

[0080] The electronic component unit (1) has:

[0081] a base member (2) having the electronic component (10), a pair of terminals (30) connected to the electronic component (10) and extending in a prescribed direction, and a housing body (20) that internally houses the electronic component (10) and has, on an outer surface, engaging portions (23) that respectively expose the pair of terminals (30) to the outside and protrude or are recessed in a direction intersecting the prescribed direction;

[0082] a housing (3) that is assembled to the base member (2) and houses the pair of terminals (30) so as to be isolated from each other,

[0083] The manufacturing method has:

[0084] a first step of manufacturing the base member (2); and

[0085] a second step of selecting one of a connector-type housing (3A) having a connector shape and a casing-type housing (3B) having a casing shape as the housing (3), and assembling the selected housing (3) to the base member (2), the connector-type housing (3A) being integrally overmolded to the base member (2) and having fitting openings (91) that expose one end of the pair of terminals (30) to the outside, the casing-type housing (3B) being assembled in a manner that engages with the base member (2) and having a pair of housing chambers (78) that house the pair of terminals (30) so as to be isolated from each other,

[0086] In the second step,

[0087] in a case where the connector-type housing (3A) is selected, the connector-type housing (3A) is integrally overmolded to the base member (2) in a manner that fills the engaging portions (23) of the housing body (20) of the base member (2) and exposes the one end to the fitting openings (91),

[0088] in a case where the casing-type housing (3B) is selected, after a pair of electric wires (6) are connected to the pair of terminals (30), the casing-type housing (3B) is assembled to the base member (2) in a manner that engages with the engaging portions (23) of the housing body (20) of the base member (2), houses the pair of terminals (30) in the pair of housing chambers (78), and allows the pair of electric wires (6) to pass through the inside and outside of each of the pair of housing chambers (78).

[0089] According to the electronic component unit manufacturing method described in [1] above, the base member can be used as a general-purpose component regardless of whether a connector-type housing or a case-type housing is selected. In the case of selecting the connector-type housing, by integrally adding the connector-type housing to the base member by overmolding the engagement portion of the receiving body of the base member, the pair of terminals of the base member can be properly insulated, and the connector-type housing and the base member can be firmly integrated. Thus, for example, even in the case where an external force such as rotation is applied to the connector-type housing while one of the base member and the connector-type housing is fixed, the connector-type housing and the base member can be prevented from separating. On the other hand, in the case of selecting the case-type housing, by assembling the case-type housing to the base member so as to engage with the engagement portion of the receiving body of the base member, and by receiving the pair of terminals in the pair of receiving chambers, the pair of terminals of the base member can be properly insulated, and the base member can hold the case-type housing with sufficient strength. Thus, for example, as described above, the case-type housing and the base member can be prevented from separating. Therefore, according to the electronic component unit manufacturing method of the present structure, by using the base member as a general-purpose component, the electronic component unit corresponding to a plurality of specifications can be manufactured at low cost by changing the housing according to the specifications.

[0090] [2] The manufacturing method described in [1] above, wherein an electronic component unit (1) is manufactured, wherein

[0091] the base member (2) has a recess (27) on an outer surface between the pair of terminals (30),

[0092] the connector-type housing (3A) is shaped so as to fill the recess (27),

[0093] the case-type housing (3B) has a partition wall (74) that is inserted into the recess (27) and separates the pair of receiving chambers (78).

[0094] According to the electronic component unit manufacturing method described in [2] above, by filling the recess of the receiving body of the base member with the connector-type housing, or by inserting the partition wall of the case-type housing into the recess, the face distance between the pair of terminals can be extended, and the pair of terminals can be more reliably insulated.

[0095] [3] An electronic component unit (1) comprising:

[0096] The base member (2) has an electronic component (10), a pair of terminals (30) connected to the electronic component (10) and extending in a prescribed direction, and a housing (20) that internally houses the electronic component (10) and has a fitting portion (23) on an outer surface that externally exposes the pair of terminals (30) and protrudes or is recessed in a direction intersecting the prescribed direction;

[0097] The housing (3A) is integrally formed with the base member (2), fills the fitting portion (23) of the housing (20) of the base member (2), and has a fitting hole (91) that exposes one end of the pair of terminals (30).

[0098] The electronic component unit according to the above [3], by integrally forming the housing in a manner that fills the fitting portion of the housing of the base member, can appropriately insulate the pair of terminals of the base member, and firmly integrate the housing and the base member. Thus, for example, even in the case where an external force that fixes one of the base member and the housing and rotates the other acts on the housing, the housing and the base member can be prevented from separating. Therefore, the electronic component unit of the present application is excellent in durability.

[0099] [4] The electronic component unit (1) according to the above [3], wherein

[0100] The base member (2) has a recessed portion (27) on an outer surface between the pair of terminals (30),

[0101] The housing (3A) is formed in a manner that fills the recessed portion (27).

[0102] The electronic component unit according to the above [4], by filling the recessed portion of the housing of the base member, can lengthen the surface distance between the pair of terminals, and more reliably insulate the pair of terminals.
