Technical Field
[0001] The present disclosure relates to a connection structure between a terminal and an electric wire. Background Art
[0002] As a connection structure for connecting a covered wire formed by surrounding a conductor with an insulating sheath, a connection device described in Japanese Patent Publication No. 2020-187997 (hereinafter referred to as Patent Document 1) is known. The connection device includes a pressing member, a movable side conducting member, and a fixed side conducting member. The pressing member is made of an electrically insulating rubber material and can be elastically deformed.
[0003] The movable side conducting member is composed of a metal plate such as copper or aluminum, and is formed into a shape long in the front-to-back direction as a whole. The movable side conducting member is fixed to the pressing member in a state of being fitted in a receiving recess on the upper surface of the pressing member. The movable side conducting member is a single component having a first contact portion, a second contact portion, and a connecting portion connecting the first contact portion and the second contact portion.
[0004] The fixed-side conducting member is made of a metal plate such as copper or aluminum, and is a single component formed integrally by arranging the mounting portion, the first contact portion, the mounting portion, the second contact portion, and the mounting portion in sequence. The fixed-side conducting member is fixedly mounted on the top surface of the connecting portion formed by the housing made of synthetic resin material. On the other hand, the pressing member is arranged in a state of being placed on the bottom surface of the connecting portion.
[0005] The fixed-side conductive member is located above the pressing member and the movable-side conductive member, and is opposed to the movable-side conductive member in the vertical direction with a predetermined interval therebetween. The first contact portion and the second contact portion protrude toward the movable-side conductive member. The vertical interval between the lower ends of the first contact portion and the second contact portion and the upper surface of the movable-side conductive member in a state where the pressing member is not elastically deformed is set to a size smaller than the outer diameter of the conductor.
[0006] The connection between the conductor and the first contact portion and the first contact portion is performed by inserting the connection end of the conductor into the connection portion and clamping it between the first contact portion and the first contact portion in an inserted manner. When the pressing member is not elastically deformed, the interval between the first contact portion and the first contact portion is smaller than the outer diameter of the connection end, so the connection end displaces the first contact portion downward and causes the pressing member to elastically deform in a manner of squeezing it upward and downward. Under the action of the elastic restoring force of the pressing member, the conductor and the first contact portion are connected at a specified contact pressure so as to be conductive, and the conductor and the first contact portion are connected at a specified contact pressure so as to be conductive. The connection between the conductor and the second contact portion and the second contact portion is performed in the same manner. Thus, a pair of conductors are connected via the connecting device so as to be conductive. Prior art literature Patent Literature

[0012] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described below. (1) The connection structure of the terminal and the electric wire disclosed in the present invention comprises a first electric wire, a second electric wire, and a terminal connecting the first electric wire and the second electric wire, wherein the first electric wire has a first core wire and a first insulating coating surrounding the first core wire, and the second electric wire has a second core wire and a second insulating coating surrounding the second core wire, and the terminal has a first connecting portion connected to the first core wire, a second connecting portion connected to the second core wire, and a connecting portion connecting the first connecting portion and the second connecting portion, wherein the first connecting portion is a single component integrally formed with a first receiving portion and a first contact pressure imparting portion, wherein the first receiving portion is used to receive the first core wire, and the first contact pressure imparting portion imparts a specified contact pressure to the first core wire by pressing the first core wire between the first receiving portion and the first receiving portion.
[0013] According to the above connection structure, since the first receiving portion and the first contact pressure imparting portion constituting the first connection portion are integrally formed as a single component, the spacing (the dimension between the first receiving portion and the first contact pressure imparting portion) can be easily managed. The first core wire of the first electric wire is pressed by being inserted between the first receiving portion and the first contact pressure imparting portion, thereby receiving a predetermined contact pressure, so that the first core wire is connected to the first connection portion so as to be conductive.
[0014] (2) Preferably, the first connecting portion, the linking portion and the second connecting portion are arranged along the front-to-back direction, the first receiving portion is in the shape of a flat plate and is formed to be long in the front-to-back direction, and a pair of the first contact pressure applying portions are provided in the form of standing up from the left and right side edges of the first receiving portion, and the pair of the first contact pressure applying portions are provided in a left-right symmetrical manner with respect to an axis extending along the up-down direction from the center of the left-right direction of the first receiving portion, and the first connecting portion is formed to be cylindrical in shape when viewed from the front-to-back direction through the first receiving portion and the pair of the first contact pressure applying portions. Since the first connection portion is formed in a cylindrical shape, it is easy to measure the distance from the front-back direction, and the distance management can be performed more easily.
[0015] (3) Preferably, the first receiving portion has a reinforcing rib protruding toward the first core line and extending along the front-rear direction, and the first contact pressure imparting portion has a reinforcing rib protruding toward the first core line and extending along the front-rear direction. Since the first receiving portion contacts the first core wire via the reinforcing ribs and the first contact pressure imparting portion contacts the first core wire via the reinforcing ribs, high contact pressure can be imparted to the first core wire without providing elastic members such as elastic contact pieces in the first connecting portion.
[0016] (4) Preferably, the first connection portion and the second connection portion are a single component having the same shape, and the first connection portion, the coupling portion, and the second connection portion are integrally formed. In this way, the spacing of the second connecting portion (the dimension between the second receiving portion and the second contact pressure imparting portion) can also be easily managed. The second core wire of the second electric wire is pressed by being inserted between the second receiving portion and the second contact pressure imparting portion, thereby receiving a predetermined contact pressure, so that the second core wire is connected to the second connecting portion so as to be conductive. Since the first connecting portion, the connecting portion and the second connecting portion are formed integrally, the first electric wire and the second electric wire are connected via the terminal so as to be conductive.
[0017] [Details of the embodiments of the present disclosure] Hereinafter, specific examples of the connection structure between the terminal and the electric wire of the present disclosure will be described with reference to the drawings. In addition, the present disclosure is not limited to these examples, but is indicated by the claims, and is intended to include all changes within the meaning and scope of the claims and their equivalents.
[0018] <Implementation method 1> Reference Figure 1 to Figure 5 In the following description, the embodiment 1 of the present disclosure will be described. Figure 3 Set the up and down directions in the diagram shown in the figure to the up and down directions. Figure 3 Set the left-right direction as shown in the figure, Figure 1 and Figure 2 The terminal 20 is described with its longitudinal direction being the front-rear direction and the first and second electric wires 11 and 12 being inserted into the terminal 20 being the front direction. In addition, for a plurality of identical components, only some of the components are denoted by reference numerals, and reference numerals for other components may be omitted.
[0019] like Figure 1As shown, the terminal and wire connection structure 10 of this embodiment includes a first wire 11, a second wire 12, and a terminal 20. The first wire 11 is a well-known wire formed by surrounding a first core wire 11A composed of a conductive single core wire or a metal thin wire with a first insulating sheath 11B. Similarly, the second wire 12 is a well-known wire formed by surrounding a second core wire 12A composed of a conductive single core wire or a metal thin wire with a second insulating sheath 12B.
[0020] The terminal 20 is made of metal and is a female terminal in a cylindrical shape. The terminal 20 is formed into a predetermined shape by a known method such as stamping, cutting, and casting. The metal constituting the terminal 20 can be appropriately selected from any metal such as copper, copper alloy, aluminum, aluminum alloy, stainless steel, etc. as needed. A plating layer can also be formed on the surface of the terminal 20. The metal constituting the plating layer can be appropriately selected from any metal such as tin, nickel, silver, etc. as needed.
[0021] The terminal 20 includes a first connection portion 21 connected to the first core wire 11A, a second connection portion 22 connected to the second core wire 12A, and a connection portion 23 connecting the first connection portion 21 and the second connection portion 22. The first connection portion 21, the connection portion 23, and the second connection portion 22 are arranged in sequence along the front-to-back direction. Hereinafter, the side of the connection portion 23 when viewed from the first connection portion 21 is set as the front side, and the side of the connection portion 23 when viewed from the second connection portion 22 is set as the front side.
[0022] The first connection part 21 and the second connection part 22 are a single component of the same shape, and the first connection part 21, the connecting part 23 and the second connection part 22 are formed integrally. In the following, only the structure of the first connection part 21 is described, and the description of the structure of the second connection part 22 is omitted. For the same structure as the first connection part 21, the same letters as the first connection part 21 are used in the letter part of the figure mark.
[0023] like Figure 3 As shown, the first connecting portion 21 includes a first receiving portion 21A receiving the first core wire 11A and a pair of first contact pressure imparting portions 21B rising from the left and right side edges of the first receiving portion 21A. The first receiving portion 21A and the pair of first contact pressure imparting portions 21B are formed integrally. That is, the first connecting portion 21 is a single component integrally formed with the first receiving portion 21A and the pair of first contact pressure imparting portions 21B.
[0024] like Figure 1 and Figure 2As shown, the first receiving portion 21A is flat and formed in a long shape in the front-to-back direction. The first receiving portion 21A, the bottom wall of the connecting portion 23 and the second receiving portion 22A are flat and formed in the same plane. A locking structure for locking a housing (not shown) for accommodating the terminal 20, a rubber plug, etc. can also be provided on any one of the first receiving portion 21A, the bottom wall of the connecting portion 23 and the second receiving portion 22A. A pair of first contact pressure imparting portions 21B are arranged symmetrically with respect to an axis L extending along the vertical direction from the center of the left-right direction of the first receiving portion 21A.
[0025] The first receiving portion 21A has a reinforcing rib 21C that protrudes upward and extends in the front-rear direction. Figure 3 In the figure, the first contact pressure imparting portion 21B on the left side (hereinafter referred to as "the first contact pressure imparting portion 21B on the left side") has a reinforcing rib 21D protruding to the lower right and extending in the front-to-back direction. Similarly, the first contact pressure imparting portion 21B on the right side (hereinafter referred to as "the first contact pressure imparting portion 21B on the right side") has a reinforcing rib 21D protruding to the lower left and extending in the front-to-back direction.
[0026] The first contact pressure imparting portion 21B on the left side is configured to extend in an arc shape in the clockwise direction in front of the reinforcing rib 21D after protruding upward from the left edge of the first receiving portion 21A. The first contact pressure imparting portion 21B on the right side is configured to extend in an arc shape in the counterclockwise direction in front of the reinforcing rib 21D after protruding upward from the right edge of the first receiving portion 21A. The first connecting portion 21 is formed in a cylindrical shape by the first receiving portion 21A and a pair of first joint imparting portions 21B when viewed from the front-back direction.
[0027] The front end of the first contact pressure imparting portion 21B on the left side and the front end of the first contact pressure imparting portion 21B on the right side are arranged opposite to each other in the left-right direction with a gap S therebetween. The gap S before the first core wire 11A is inserted into the first connecting portion 21 is set to be smaller than the gap S after the first core wire 11A is inserted into the first connecting portion 21. Therefore, when the first core wire 11A is inserted into the first connecting portion 21, the pair of contact pressure imparting portions 21B are elastically expanded and deformed in a manner of being separated in the left-right direction, and the gap S becomes larger.
[0028] The first core wire 11A is given a predetermined contact pressure by the elasticity of the pair of first contact pressure imparting portions 21B in an expanded and deformed state. The first receiving portion 21A presses the first core wire 11A upward via the reinforcing rib 21C, the first contact pressure imparting portion 21B on the left side presses the first core wire 11A to the lower right via the reinforcing rib 21D, and the first contact pressure imparting portion 21B on the right side presses the first core wire 11A to the lower left via the reinforcing rib 21D. That is, since the three reinforcing ribs 21C and 21D are configured to protrude toward the first core wire 11A in a configuration that surrounds the first core wire 11A, the first core wire 11A receives a predetermined contact pressure from the three reinforcing ribs 21C and 21D.
[0029] When the first core wire 11A of the first electric wire 11 is inserted from the rear to the first connecting portion 21, the first core wire 11A receives a predetermined contact pressure due to the reinforcing ribs 21C of the first receiving portion 21A and the pair of reinforcing ribs 21D of the pair of first contact pressure imparting portions 21B, thereby connecting the first core wire 11A to the first connecting portion 21 so as to be conductive. Similarly, when the second core wire 12A of the second electric wire 12 is inserted from the rear to the second connecting portion 22, the second core wire 12A receives a predetermined contact pressure due to the reinforcing ribs 22C of the second receiving portion 22A and the pair of reinforcing ribs 22D of the pair of second contact pressure imparting portions 22B, thereby connecting the second core wire 12A to the second connecting portion 22 so as to be conductive. Thus, the first electric wire 11 and the second electric wire 12 are connected via the terminal 20 so as to be conductive.
[0030] like Figure 4 As shown, the terminal 20 can also be received in the receiving hole 31 of the first rubber stopper 30. In addition to the contact pressure generated by the elasticity of the pair of first contact pressure imparting portions 21B, the contact pressure generated by the elasticity of the first rubber stopper 30 is also imparted to the first core wire 11A, so that a higher contact pressure can be imparted to the first core wire 11A.
[0031] exist Figure 4 In the case of the terminal 20 being inserted into the receiving hole 31 of the first rubber stopper 30, there is a possibility that the first rubber stopper 30 may be damaged by the corner of the terminal 20, causing the fragments of the first rubber stopper 30 to enter the terminal 20. As a countermeasure, Figure 5As shown, consider using a second rubber stopper 40 formed with a cutout 41. The second rubber stopper 40 has a plurality of receiving holes 42 arranged in the left-right direction on the upper and lower layers. For the receiving holes 42 on the upper layer side, a cutout 41 is provided at the upper portion of the second rubber stopper 40, and for the receiving holes 42 on the lower layer side, a cutout 41 is provided at the lower portion of the second rubber stopper 40. The plurality of terminals 20 are configured as interlocking terminals connected by a carrier 13. When the terminals 20 are inserted from the top into the second rubber stopper 40 at the same time, the terminals 20 are received in the receiving holes 42 while pressing open the cutouts 41. In this way, the second rubber stopper 40 will not be damaged by the corners of the terminals 20.
[0032] [Effects of Embodiment 1] The terminal and wire connection structure 10 disclosed in the present invention comprises a first wire 11, a second wire 12 and a terminal 20 connecting the first wire 11 and the second wire 12, wherein the first wire 11 has a first core wire 11A and a first insulating sheath 11B surrounding the first core wire 11A, and the second wire 12 has a second core wire 12A and a second insulating sheath 12B surrounding the second core wire 12A, and the terminal 20 has a first connecting portion 21 connected to the first core wire 11A, a second connecting portion 22 connected to the second core wire 12A, and a connecting portion 23 connecting the first connecting portion 21 and the second connecting portion 22, the first connecting portion 21 is a single component integrally formed with a first receiving portion 21A and a first contact pressure imparting portion 21B, wherein the first receiving portion 21A is used to receive the first core wire 11A, and the first contact pressure imparting portion 21B imparts a specified contact pressure to the first core wire 11A by pressing the first core wire 11A between the first receiving portion 21A.
[0033] According to the connection structure 10, since the first receiving portion 21A and the first contact pressure imparting portion 21B constituting the first connection portion 21 are integrally formed as a single component, it is possible to easily manage the spacing (the dimension between the first receiving portion 21A and the first contact pressure imparting portion 21B). The first core wire 11A of the first electric wire 11 is inserted between the first receiving portion 21A and the first contact pressure imparting portion 21B and is pressed, thereby receiving a predetermined contact pressure, so that the first core wire 11A and the first connection portion 21 are connected to be conductive.
[0034] Preferably, the first connection portion 21, the connecting portion 23 and the second connection portion 22 are arranged in the front-to-back direction, the first receiving portion 21A is in the shape of a flat plate and is formed to be long in the front-to-back direction, and a pair of first contact pressure applying portions 21B are provided in the form of standing up from the left and right side edges of the first receiving portion 21A, and the pair of first contact pressure applying portions 21B are provided in a left-right symmetrical manner with respect to an axis L extending along the up-down direction from the center of the left-right direction of the first receiving portion 21A, and the first connection portion 21 is formed in a cylindrical shape by the first receiving portion 21A and the pair of first contact pressure applying portions 21B when viewed from the front-to-back direction. Since the first connection portion 21 is formed in a cylindrical shape, it is easy to measure the distance from the front-back direction, and the distance management can be performed more easily.
[0035] Preferably, the first receiving portion 21A has a reinforcing rib 21C protruding toward the first core wire 11A and extending in the front-rear direction, and the first contact pressure imparting portion 21B has a reinforcing rib 21D protruding toward the first core wire 11A and extending in the front-rear direction. The first receiving portion 21A contacts the first core wire 11A via the reinforcing rib 21C, and the first contact pressure imparting portion 21B contacts the first core wire 11A via the reinforcing rib 21D. Therefore, high contact pressure can be imparted to the first core wire 11A without providing elastic parts such as elastic contact pieces in the first connecting portion 21 .
[0036] Preferably, the first connection portion 21 and the second connection portion 22 are a single component having the same shape, and the first connection portion 21 , the connecting portion 23 , and the second connection portion 22 are integrally formed. In this way, the spacing of the second connecting portion 22 (the dimension between the second receiving portion 22A and the second contact pressure imparting portion 22B) can be easily managed. The second core wire 12A of the second electric wire 12 is inserted between the second receiving portion 22A and the second contact pressure imparting portion 22B and pressed, thereby receiving a predetermined contact pressure, so that the second electric wire 12 and the second connecting portion 22 are connected to be conductive. Since the first connecting portion 21, the connecting portion 23, and the second connecting portion 22 are formed integrally, the first electric wire 11 and the second electric wire 12 are connected to be conductive via the terminal 20.
[0037] <Implementation method 2> Reference Figure 6 to Figure 8 Embodiment 2 of the present disclosure is described. The connection structure 110 between the terminal and the wire of Embodiment 2 is formed by adding an introduction shape to the terminal 20 of Embodiment 1. In the structure of the terminal 50 of Embodiment 2, for the same structure as the terminal 20 of Embodiment 1, the figure mark in which the tens digit is changed from 2 to 5 is marked, and their description is sometimes omitted.
[0038] The terminal 50 has a first connection portion 51, a second connection portion 52, a connecting portion 53, a first guide portion 54 extending backward from the rear end of the first connection portion 51, and a second guide portion 55 extending backward from the rear end of the second connection portion 52. The first guide portion 54 and the second guide portion 55 have an introduction shape formed in a manner that expands toward the rear. Since the first guide portion 54 and the second guide portion 55 are of the same shape, the first guide portion 54 is used as a representative for explanation below, and for the same structure as the first guide portion 54, the reference numeral in which the digit of the unit digit is changed from 4 to 5 is marked.
[0039] like Figure 6 and Figure 7 As shown, the first guide portion 54 is connected to the rear end of the first connection portion 51 and is integrally formed with the first connection portion 51. The first guide portion 54 is a single component integrally formed with a first bottom wall 54A and a pair of first side walls 54B rising upward from both side edges of the first bottom wall 54A.
[0040] The first bottom wall 54A is in the shape of a flat plate and is connected to the rear end of the first receiving portion 51A. Figure 8 As shown, the first bottom wall 54A is formed so that the dimension thereof increases downward and in the left-right direction as it goes toward the rear.
[0041] The first side wall 54B on the left is connected to the rear end of the first contact pressure imparting portion 51B on the left. The first side wall 54B on the left is configured to extend in an arc shape in a clockwise direction in front of a portion corresponding to the reinforcing rib 51D when viewed from the front-back direction after protruding upward from the left edge of the first bottom wall 54A.
[0042] The first side wall 54B on the right side is connected to the rear end of the first contact pressure imparting portion 51B on the right side. The first side wall 54B on the right side is configured to extend in an arc shape in the counterclockwise direction in front of the portion corresponding to the reinforcing rib 51D when viewed from the front-back direction after protruding upward from the right edge of the first bottom wall 54A.
[0043] The pair of first side walls 54B are formed such that the height dimension measured from the first bottom wall 54A increases toward the rear and the separation dimension in the left-right direction increases.
[0044] When the first core wire 11A of the first electric wire 11 is inserted from the rear to the first connection part 51, the first core wire 11A is guided by the first guide part 54 and enters the first connection part 51, and the first core wire 11A receives a predetermined contact pressure due to the reinforcing ribs 51C of the first receiving part 51A and the pair of reinforcing ribs 51D of the pair of first contact pressure applying parts 51B, thereby the first core wire 11A is connected to the first connection part 51 so as to be conductive. Similarly, when the second core wire 12A of the second electric wire 12 is inserted from the rear to the second connection part 52, the second core wire 12A is guided by the second guide part 55 and enters the second connection part 52, and the second core wire 12A receives a predetermined contact pressure due to the reinforcing ribs 52C of the second receiving part 52A and the pair of reinforcing ribs 52D of the pair of second contact pressure applying parts 52B, thereby the second core wire 12A is connected to the second connection part 52 so as to be conductive. Thus, the first electric wire 11 and the second electric wire 12 are connected to be conductive via the terminal 50.
