Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a terminal connection structure for connecting a terminal to a conductive wire disposed on a surface of a plate member such as a plate glass. In particular, in a vehicle such as an automobile, the present invention relates to a terminal connection structure for energizing a heat ray printed on a window glass to prevent fogging.
[0002]
[Prior art]
  A hot wire for preventing fogging is printed on a window glass of a vehicle, for example, a rear window of an automobile. As a terminal connection structure for energizing such a heat ray, conventionally, JP-A-7-329724 (published on December 19, 1995), JP-A-9-76748 (published on March 25, 1997). ), And those using connection terminals disclosed in Japanese Patent Laid-Open No. 9-226522 (published on Sep. 2, 1997) have been proposed.
[0003]
  The connection terminals disclosed in the above three publications are all soldered and connected to the hot wire. For example, in the connection terminal disclosed in Japanese Patent Laid-Open No. 7-329724, solder 200 is applied to one end of the connection terminal 100 and the other end is inserted into the connector 300 as shown in FIG. It is the composition to do. That is, the configuration is such that the current applied to the connector 300 from the vehicle side is supplied to the heat wire of the rear window via the connection terminal 100 and the solder 200.
[0004]
  Further, a connection terminal as shown in FIG. 13 has been proposed as a conventional connection terminal. That is, the tongue piece 500 provided on the disk-shaped connection terminal 400 is pressure-bonded to the disk-shaped head 700 provided on the guide rod 600. On the other hand, the connection terminal 400 is provided with a male crimp terminal 900 for crimping a female crimp terminal 800 to which a current is applied from the vehicle side.
[0005]
  Further, the guide rod 600 is fitted into the spring 1000, and the connection terminal 400 is urged by the spring 1000 to a heat wire (not shown) of the rear window. Thereby, the connection terminal 400 and the heat wire of the rear window are electrically connected to prevent fogging.
[0006]
[Problems to be solved by the invention]
  However, the conventional connection terminals have the following problems.
[0007]
  That is, in the connection terminal configured to be electrically connected to the heat wire using solder, a step of soldering the heat wire and the connection terminal is required when the rear window is mounted on the vehicle. Due to this soldering process, there is a problem that the vehicle assembly work becomes complicated and the cost of the vehicle is increased.
[0008]
  Further, the connection terminal 100 shown in FIG. 12 has the following problems. That is, as shown in FIG. 14, the connection terminal 100 is soldered together with the connector 300 to the heat wire 1200 printed on the rear window 1100 outside the space surrounded by the outer panel 1300 and the inner panel 1400. Further, a ceramic paint 1500 or the like is applied to the surface of the rear window 1100 on the connection terminal 100 side to prevent the connection terminal 100 from being seen through from the outside of the vehicle.
[0009]
  However, the harness 1700 connected to the inside of the vehicle from the connection terminal 100 is passed between the outer panel 1300 and the inner panel 1400 or a hole formed in the side wall of the inner panel 1400 as shown in FIG. Passed through.
[0010]
  That is, when a current is applied to the heat wire 1200 using the conventional connection terminal 100, the connection terminal 100 and the connector 300 are exposed to the inside of the vehicle, and there is a problem that the appearance of the vehicle interior deteriorates.
[0011]
  On the other hand, the connection terminal 400 shown in FIG. 13 has the following problems. That is, as shown in FIG. 15, the guide rod 600 provided with the spring 1000 is provided so that it can slide in the support base 1600 provided on the inner panel 1400. Thereby, the connection terminal 400 is urged by the heat wire 1200 of the rear window 1100. Further, a ceramic paint 1500 or the like is applied to the surface of the rear window 1100 on the connection terminal 400 side to prevent the connection terminal 400 from being seen through from the outside of the vehicle.
[0012]
  However, for example, it is assumed that a manufacturing process in which the inner panel 1400 is assembled from the upper side while the rear window 1100 is placed on the lower side is performed. Then, when the inner panel 1400 is transferred, a configuration for preventing the guide bar 600 from falling off the support base 1600 is required. Providing such a configuration not only complicates the manufacturing process but also increases the cost of the vehicle.
[0013]
  The present invention has been made in view of the above-described conventional problems, and its purpose is to incorporate a terminal through a simplified process and to reduce the cost of the product. It is an object of the present invention to provide a terminal connection structure that can prevent a contact portion from affecting the appearance of a product.
[0014]
[Means for Solving the Problems]
  In order to solve the above problems, the terminal connection structure of the present invention includes a plate member having a conductive wire, and a panel member that supports the plate member so that a cavity is formed between the plate member, In the terminal connection structure for applying a current by bringing a terminal portion into contact with the conductive wire, a biasing means for biasing and contacting the terminal portion with the conductive wire, a cavity formed by the plate member and the panel member And a first support means for supporting the terminal portion and the biasing means. The first support means includes the terminal portion as described above. A stopper is provided that stops at a contact position with the conductive wire, and a passage is formed through which the terminal portion passes from the outside of the first support means to the contact position with the conductive wire. Said first support means Withdrawal of the terminal section of al, or are characterized in that to allow the assembly of the terminal section with respect to the first support means.
[0015]
  In other words, the terminal connection structure of the present invention applies current by bringing the terminal portion into contact with the conductive wire printed on the surface of the plate member supported by the panel member.
[0016]
  By the way, in the conventional terminal connection structure, since the terminal portion is brought into contact with the conductive wire by soldering or the like, the process of assembling the terminal portion may be complicated and the cost of the product may be increased.
[0017]
  Moreover, if a terminal part is provided in the cavity formed between the plate member and the panel member, a space necessary for soldering cannot be ensured. Therefore, the conventional terminal connection structure using soldering affects the appearance of the product by exposing the contact portion between the conductive wire and the terminal portion outside the cavity formed between the plate member and the panel member. There is also a problem.
[0018]
  In addition, although a configuration in which the terminal portion is brought into contact with the conductive wire by a spring has been proposed in the past, the configuration for dropping the spring and the terminal portion from the panel member in the process of incorporating the terminal portion is separated from the terminal connection structure. It is necessary to provide it. That is, this configuration has problems from the viewpoint of simplifying the process of incorporating the terminal portion and reducing the cost of the product. In addition, the support structure of the terminal portion becomes large, and there is a problem that the thickness of the product becomes thick.
[0019]
  Therefore, the terminal connection structure according to the present invention particularly opposes the conductive wire in the cavity formed by the urging means for urging and contacting the terminal portion with the conductive wire, and the plate member and the panel member. And a first support means for supporting the terminal portion and the urging means, wherein the first support means places the terminal portion in a contact position with the conductive wire. A stopper is provided for stopping, and a passage is formed through which the terminal portion passes from the outside of the first support means to a contact position with the conductive wire, and the passage extends from the first support means. The terminal portion can be extracted or the terminal portion can be assembled to the first support means.
[0020]
  That is, in the terminal connection structure of the present invention, the conductive wire and the terminal portion are brought into contact with each other by the biasing means without using solder. Therefore, the terminal connection structure of the present invention can simplify the manufacturing process and reduce the cost of the product.
[0021]
  Further, the terminal portion and the biasing means in the present invention are supported by the first support means in the cavity surrounded by the panel member and the plate member. Therefore, the contact portion between the terminal portion and the conductive wire is accommodated in a cavity surrounded by the panel member and the plate member. Thereby, the terminal connection structure of this invention can prevent the contact part of a conductive wire and a terminal part from exposing and affecting the appearance of a product.
[0022]
  Furthermore, the terminal portion is stopped by a stopper provided in the first support means at the contact position with the conductive wire. Therefore, the terminal portion is prevented from falling off from the first support means. As a result, the terminal connection structure itself can prevent the terminal portion from dropping off in the terminal portion assembling step, so that the assembling step can be simplified and the cost of the product can be reduced.
[0023]
  Moreover, according to the said structure, it becomes possible to pass through the said channel | path and to extract a terminal part from a 1st support means, or to assemble | attach a terminal part to a 1st support means. Therefore, it is possible to easily replace the terminal portion when the contact failure occurs between the terminal portion and the conductive wire.
[0024]
  In the terminal connection structure of the present invention, the first support means includes a first wall surface, a second wall surface, and a third wall surface that are connected to each other, has a U-shape, and the stopper includes It is preferable that the U-shaped portion formed by these three wall surfaces is formed so as to cover a part and an opening for projecting the terminal portion is formed..
[0025]
DETAILED DESCRIPTION OF THE INVENTION
    [Embodiment 1]
  An embodiment of the present invention will be described with reference to FIGS. 1 to 5 as follows.
[0026]
  As shown in FIG. 1, the terminal connection structure 1 in the present embodiment includes a pedestal (first support means) 3 provided on an inner panel (panel member) 2 of a vehicle, a connection terminal (terminal portion) 4, and the like. And a spring (biasing means, elastic body) 5.
[0027]
  As shown in FIG. 2, the pedestal 3 is provided at the side end of the opening 6 in the inner panel 2 mounted on the hatchback portion of the automobile. The opening 6 is formed in the inner panel 2 in order to fit a rear window (plate member).
[0028]
  FIG. 3 shows the pedestal 3 and its surroundings in an enlarged manner. The pedestal 3 includes a first wall surface 7, a second wall surface 8, and a third wall surface 9 that extend in a direction facing the rear window (not shown) from the inner panel 2. The rear window is fitted on the front side of the paper with respect to the inner panel 2. That is, the direction facing the rear window refers to the direction toward the front side of the page in FIG.
[0029]
  The first wall surface 7, the second wall surface 8, and the third wall surface 9 are connected to each other and have a U-shape when viewed from the rear window side. Moreover, the 4th wall surface 10 is formed in the upper part of these three wall surfaces so that a part in U shape formed by these three wall surfaces may be covered.
[0030]
  The fourth wall surface (stopper) 10 is formed with an opening 11 for projecting the connection terminal 4. The connection terminal 4 is disposed so as to protrude from the opening 11 through the opening formed by the first wall surface 7, the second wall surface 8, and the fourth wall surface 10.
[0031]
  Next, the structure of the connection terminal 4 will be described with reference to FIG. As shown in FIG. 4, the connection terminal 4 has a connection projection 13 formed on the surface of the cross-shaped flat plate 12 on the rear window side. Further, from the end of the flat plate 12, first tongue pieces 14 a, 14 b, 14 c, and 14 d extend substantially perpendicular to the direction of the inner panel.
[0032]
  The spring 5 is received in a space formed by the four first tongue pieces 14 a, 14 b, 14 c, and 14 d and the flat plate 12. Of the four first tongue pieces, the two first tongue pieces 14 a and 14 b include second tongue pieces 15 a and 15 b that extend substantially perpendicularly from the end portions of the respective tongue pieces toward the outside of the connection terminal 4. ing. Further, a crimp terminal 16 is provided at the tip of the second tongue piece 15a.
[0033]
  According to the above configuration, the crimp terminal 16 can be crimped to the harness 17 to which an electric current is applied from the vehicle body side, and the connecting convex portion 13 is connected to the rear window heat ray (conductive wire) using the biasing force of the spring 5. Can be pressed against. Thereby, an electric current can be given to the heat wire of the rear window through the connection convex portion 13 of the connection terminal 4.
[0034]
  That is, as shown in FIG. 5, the connection terminal 4 protrudes from the opening 11 in the fourth wall surface 10 of the base 3, while holding the spring 5 between the inner panel 2. That is, the connection terminal 4 is urged by the spring 5 toward the heat wire (conductive wire) 19 printed on the rear window 18. The surface of the rear window 18 on the connection terminal 4 side is coated with a ceramic paint 18a and the like to prevent the connection terminal 4 from being seen through from the outside of the vehicle.
[0035]
  As described above, the terminal connection structure 1 according to the present embodiment includes the inner panel 2 and the outer panel that support the rear window 18 so that a cavity is formed between the rear window 18 having the heat wire 19 and the rear window 18 ( Panel member) 20, and the connection terminal 4 is brought into contact with the heat wire 19 to apply a current.
[0036]
  Furthermore, the terminal connection structure 1 is provided at a position facing the heat wire 19 in a cavity formed by the spring 5 that urges and contacts the connection terminal 4 to the heat wire 19, and the rear window 18, the inner panel 2, and the outer panel 20. And a pedestal 3 that supports the connection terminal 4 and the spring 5. In particular, the pedestal 3 includes a fourth wall surface 10 that stops the connection terminal 4 at the position of contact with the heat wire 19.
[0037]
  That is, the terminal connection structure 1 of the present embodiment applies a current to the heat wire 19 by bringing the connection terminal 4 and the heat wire 19 into contact with each other using the biasing force of the spring 5. That is, since it is not necessary to perform soldering or the like in order to apply a current to the hot wire 19, it is possible to simplify the manufacturing process and reduce the cost.
[0038]
  Further, the connection terminal 4 and the spring 5 in the present embodiment are supported by the pedestal 3 in a cavity surrounded by the inner panel 2, the outer panel 20 and the rear window 18. Therefore, the contact portion between the connection terminal 4 and the heat wire 19 is accommodated in the cavity. Thereby, the terminal connection structure 1 of this Embodiment can prevent that the contact part of the connection terminal 4 and the heat ray 19 exposes, and influences a vehicle interior.
[0039]
  Further, the case where the rear window 18 is supported only by the inner panel 2 as shown in FIG. 6 instead of the configuration in which the rear window 18 is arranged outside the outer panel 20 (see FIG. 5) will be described. The surface of the rear window 18 on the connection terminal 4 side is coated with a ceramic paint 18a and the like to prevent the connection terminal 4 from being seen through from the outside of the vehicle.
[0040]
  As shown in FIG. 6, even when the rear window 18 is supported only by the inner panel 2, the connection terminal 4 and the spring 5 are supported in a cavity surrounded by the inner panel 2 and the rear window 18. The pedestal 3 can be arranged to do so. Therefore, by using the terminal connection structure 1 of the present embodiment, it is possible to prevent the contact portion between the connection terminal 4 and the heat wire 19 from being exposed and affecting the appearance of the product.
[0041]
  Further, when the second tongue pieces 15 a and 15 b of the connection terminal 4 and the fourth wall surface 10 of the pedestal 3 come into contact with each other by the biasing force of the spring 5, the connection terminal 4 does not advance in the direction of the rear window 18. That is, the connection terminal 4 is prevented from jumping out of the base 3.
[0042]
  Therefore, even when the rear window 18 is placed on the lower side and the inner panel 2 is assembled from the upper side, the connection terminal 4 is prevented from jumping out of the base 3. Therefore, the manufacturing equipment can be arranged in a more free layout, and the rear window 18 can be assembled, and the cost of the vehicle can be reduced. Further, the connection terminal 4 can be prevented from popping out with a simple configuration, and the thickness of the product can be reduced.
[0043]
  By the way, the terminal connection structure 1 of this Embodiment has an advantage compared with the conventional connection terminal structure in the following points. In other words, in the conventional terminal connection structure (see FIGS. 13 and 15), the connection terminal 400 and the heat wire 1200 are in poor contact, and the rear window 1100 can be removed when the connection terminal 400 or the spring 1000 is replaced. Necessary. Due to the time required to remove the rear window, the repair work becomes complicated.
[0044]
  On the other hand, in the terminal connection structure 1 according to the present embodiment, the connection terminal 4 and the spring 5 can be exchanged in the following steps. That is, as shown in FIG. 5 or FIG. 6, the spring 5 can be extracted by making a hole in a portion of the inner panel 2 where the spring 5 is in contact.
[0045]
  Furthermore, in the terminal connection structure 1 of the present embodiment, in the pedestal 3, the passage through which the connection terminal 4 passes from the outside of the pedestal 3 to the contact position with the heat ray 19 includes the first wall surface 7, the second wall surface 8, and the first wall surface. 4 wall surfaces 10 are formed (see FIG. 3). In the terminal connection structure 1 of the present embodiment, the connection terminal 4 can be extracted from the passage formed in this way.
[0046]
  Therefore, the connection terminal 4 and the spring 5 can be extracted and replaced without removing the rear window 18. Therefore, the contact failure between the heat wire 19 and the connection terminal 4 can be repaired by a simplified process.
[0047]
  In addition, the terminal connection structure 1 of this Embodiment described the case where the shape of the flat plate 12 was a cross shape. However, the shape of the flat plate 12 is not limited to a cross shape. That is, the flat plate 12 may be formed in a disc shape having a diameter slightly larger than the diameter of the spring 5. The spring 5 can be replaced by an elastic body such as sponge or rubber.
[0048]
    [Reference Example 1]
  Of the present inventionReference exampleThis will be described with reference to FIG. 7 and FIG. For convenience of explanation, members having the same functions as those shown in the drawings of the first embodiment are given the same reference numerals, and descriptions thereof are omitted.
[0049]
  BookReference exampleAs shown in FIG. 7, a pedestal (first support means) 30 used in the terminal connection structure of the first wall surface 7, the second wall surface 8, the third wall surface 9, and a fourth wall surface having an opening 11 is provided. 10. That is, the pedestal 30 has the same configuration as the configuration of the pedestal 3 in the first embodiment in that it includes four wall surfaces.
[0050]
  Also bookReference exampleThe pedestal 30 is provided with a fifth wall surface (second support means) 31 between the inner panel 2 and the fourth wall surface 10 so as to be parallel to the fourth wall surface 10.
[0051]
  The advantage of providing the fifth wall surface 31 will be described with reference to FIG. 8 shows a configuration in which the rear window 18 is sandwiched between the inner panel 2 and the outer panel 20, unlike the configuration examples shown in FIG. 5 and FIG. Also bookReference exampleThe terminal connection structure 1 'uses the connection terminal 4 having the configuration described in the first embodiment.
[0052]
  Even if the rear window 18 is arranged as shown in FIG.Reference exampleThe terminal connection structure 1 ′ is provided at a position facing the heat wire 19 in a cavity formed by the spring 5 that biases and contacts the connection terminal 4 to the heat wire 19, and the rear window 18, the inner panel 2, and the outer panel 20. And a pedestal 3 that supports the connection terminal 4 and the spring 5. In particular, the pedestal 3 includes a fourth wall surface 10 that stops the connection terminal 4 at the position of contact with the heat wire 19. That is, the same effects as those of the terminal connection structure 1 in [Embodiment 1] described above are obtained.Reference exampleThe terminal connection structure 1 ′ can also be obtained.
[0053]
  In particular, the bookReference exampleIn the terminal connection structure 1 ′, since the fifth wall surface 31 is provided, a spring 5 having a length from the connection terminal 4 to the fifth wall surface 31 may be used. That is, bookReference exampleThe terminal connection structure 1 ′ has an advantage that it is not necessary to use a spring 5 having a length from the connection terminal 4 to the inner panel 2.
[0054]
  Therefore, the spring 5 can be selected according to the length from the connection terminal 4 to the fifth wall surface 31 regardless of the depth of the inner panel 2 viewed from the rear window 18. That is, the length of the spring 5 can be adjusted by the position of the fifth wall surface 31. Thereby, since springs having various lengths can be used as the spring 5, the degree of freedom in design is increased.
[0055]
    [Reference Example 2]
  Of the present inventionotherA reference example will be described below with reference to FIG. For convenience of explanation, the first embodiment described above is used.Reference example 1The members having the same functions as those shown in the drawings are denoted by the same reference numerals, and the description thereof is omitted.
[0056]
  As shown in FIG. 9A, the connection terminal (terminal portion) 21 used in the terminal connection structure of the present reference example includes a rectangular flat plate 12, a connecting projection 13, and first tongue pieces 14a and 14b. And second tongue pieces 15a and 15b. That is, the connection terminal 21 of the present reference example has a configuration in which the flat plate 12 is formed in a rectangular shape instead of a cross shape with respect to the connection terminal 4 in Embodiment 1, and the first tongue pieces 14c and 14d are omitted. Can do.
[0057]
  Moreover, the part which contacts the heat ray 19 in the connection terminal 21 in this reference example is cut and raised toward the heat ray 19 so that it protrudes from other parts in the flat plate 12.
[0058]
  That is, as shown in FIG. 9B, the portion surrounding the connecting convex portion 13 in the flat plate 12 is configured as a cantilever. Therefore, the connection when the same force is applied from the rear window side to the inner panel side with respect to the connection convex portion 13 of the connection terminal 4 (Embodiment 1) and the connection convex portion 13 of the connection terminal 21. Comparing the movement amount of the convex portion for connection, the movement amount of the convex portion for connection 13 in this reference example is larger.
[0059]
  That is, in the present reference example, when the connecting convex portion 13 and the heat ray are in contact, the connecting convex portion 13 is pushed down to the inner panel side. Therefore, the connecting convex portion 13 is in contact with the heat ray by the restoring force to return the portion surrounding the connecting convex portion 13 in the flat plate 12 to the state where it is not pushed down and the urging force of the spring 5. Can do.
[0060]
  On the other hand, when the connecting convex portion 13 and the heat ray are in contact with each other in the first embodiment, even if the connecting convex portion 13 is pushed down to the inner panel side, the pushed distance is small.
[0061]
  That is, when the restoring force that tries to return to the state where the portion surrounding the connecting convex portion 13 in the flat plate 12 is not pushed down is compared between the first embodiment and the present reference example, the restoring force in the first embodiment is It is considerably smaller than this reference example. Therefore, in the first embodiment, it can be said that the connecting convex portion 13 is substantially in contact with the heat ray only by the urging force of the spring 5.
[0062]
  Therefore, the connection terminal 21 in the present reference example can contact the connection projection 13 and the heat ray with a larger force than the connection terminal 4 in the first embodiment. Thereby, the contact failure of the connection terminal 21 and the convex part 13 for a connection can be prevented more reliably.
[0063]
    [Reference Example 3]
  Still another reference example of the present invention will be described below with reference to FIGS. For convenience of explanation, the aboveEmbodiment 1, Reference Example 1 and 2The members having the same functions as those shown in the drawings are denoted by the same reference numerals, and the description thereof is omitted.
[0064]
  As shown in FIG. 10, the connection terminal (terminal portion, biasing means) 40 used in this reference example includes a rectangular flat plate 12, a connecting convex portion 13, first tongue pieces 14 a and 14 b, Two tongue pieces 15a and 15b are provided.
[0065]
  The connection terminal 40 of this reference example is particularly characterized in that the flat plate 12 and the first tongue piece 14a, and the first tongue piece 14a and the second tongue piece 15a are connected so as to form an acute angle, respectively. is there. Further, the flat plate 12 and the first tongue piece 14b, and the first tongue piece 14b and the second tongue piece 15b are respectively connected to form an acute angle.
[0066]
  Thus, the connection terminal 40 of this reference example is configured such that the flat plate 12, the first tongue piece 14a (14b), and the second tongue piece 15a (15b) form a Z-shaped leaf spring. ing. Thereby, the connection terminal 40 itself can be provided with a function as an urging means for urging the connecting convex portion 13 toward the heat wire 19.
[0067]
  Therefore, as shown in FIG. 11, the connecting convex portion 13 can be brought into contact with the heat wire 19 by the restoring force of the connecting terminal 40 as a leaf spring. That is, it is possible to electrically connect the heat wire 19 and the connection terminal 40 without providing the spring 5. Thereby, a number of parts can be reduced more.
[0068]
  In addition, in FIG. 11, as a base of a terminal connection structure,Reference example 1Although the case where the base 30 which has the 5th wall surface 31 demonstrated in 1 is used is shown, it is not necessarily limited to this. That is, the pedestal 3 described in the first embodiment may be used in combination with the connection terminal 40 according to this reference example.
[0069]
  The terminal connection structure of the present invention is a connection structure of a terminal connected to a heat wire formed on a vehicle window glass, and is a back surface of an inner panel assembled to the window glass from the indoor side. A pedestal is provided on the side, and the terminal may have a convex portion and may be configured such that the heat ray and the terminal are connected by being assembled to the pedestal.
[0070]
  According to the terminal connection structure having the above-described configuration, since the terminal connection portion is hidden in the inner panel, the appearance is improved.
[0071]
  Further, the terminal connection structure of the present invention may be configured such that the terminal is fitted to the pedestal with an elastic body.
[0072]
  According to the terminal connection structure having the above-described configuration, the terminal can be incorporated into the pedestal, and the terminal can be crimped to the heat ray by the elastic body, and the contact between the terminal and the heat ray can be stabilized.
[0073]
  Further, the terminal connection structure of the present invention may be configured such that the pedestal includes an opening for inserting the terminal and an opening for protruding the terminal on the upper surface.
[0074]

[0075]
  Moreover, the terminal connection structure of this invention may be the structure in which the said base is equipped with the support part which supports an elastic body between a panel back surface and a base upper surface part.
[0076]

[0077]
  Moreover, the terminal connection structure of this invention WHEREIN: The structure by which the site | part which contacts the said conductive wire in the said terminal part is cut and raised toward the said conductive wire may be sufficient as the said structure.
[0078]
  According to the said structure, the site | part which contacts the conductive wire in a terminal part is cut and raised toward the conductive wire. Therefore, when a force is applied from the conductive wire to the terminal portion, a restoring force is generated in the terminal portion to restore the conductive wire. On the other hand, since the terminal portion is urged to the conductive wire by the urging means, it can be said that a force is applied from the conductive wire to the terminal portion.
[0079]
  That is, in the terminal connection structure of the present invention, the terminal portion and the conductive wire can be brought into contact with each other by the restoring force in addition to the urging force by the urging means. Therefore, the contact between the terminal portion and the conductive wire can be made more reliable, and the contact failure can be reduced.
[0080]
  Moreover, the terminal connection structure of this invention WHEREIN: The said terminal part may be formed as a leaf | plate spring in the said structure.
