Problems to be solved by the invention
In the terminal of patent document 1, the pressing portion is bent using a jig such as an anvil or a crimper, and the tip end of the pressing portion is abutted against the upper surface of the interposing portion to apply a pressing force to the flat cable. The flat cable has a conductor and a covering portion made of an insulating resin, but the insulating resin may be degraded by hydrolysis. The rate of degradation due to hydrolysis may vary depending on the pressure applied to the insulating resin and the ambient temperature. Therefore, since the pressing portion continues to apply the pressing force to the flat cable, the flat cable may be broken when exposed to, for example, a high-temperature and high-humidity environment for a long time.
The present invention has been made under the above circumstances, and an object thereof is to provide a terminal capable of suppressing damage to a connection object.

a base portion that sandwiches the connection object between the base portion and the contact portion with the contact portion;
a pressing portion that presses a distal end of the elastic plate located on a further side in the insertion direction toward the base portion; and
a restricting portion that restricts movement of the distal end in a pressing direction so as to hold the distal end in a non-contact state with respect to the base portion at a position corresponding to the distal end of the elastic plate pressed by the pressing portion.
The restricting portion may be a 1 st projecting portion projecting from the base portion toward the distal end of the elastic plate.
The projecting amount of the 1 st projecting portion may be larger than the length of the connection object in the pressing direction.
The terminal may include a folded portion that is provided at a base end of the elastic plate located on a front side in the insertion direction and is folded back toward the opening,
the elastic plate is connected to the main body portion via the folded-back portion.
The folded-back portion may be formed as an arch portion with rounded corners.
The contact portion may be formed in a cantilever shape by forming a slit in the elastic plate.
The pressing portion may be provided at a position not overlapping with a formation position of the slit in the insertion direction.
The elastic plate may have 2 nd protrusions formed at both ends in the width direction thereof corresponding to the width direction of the connection object, and the 2 nd protrusions may protrude toward the connection object inserted into the body.
The base portion may be formed with a locking portion that is locked to the object to be connected and that defines a position of the object to be connected in the insertion direction with respect to the base portion.

Detailed Description
Hereinafter, a terminal 1 according to an embodiment of the present invention will be described with reference to the drawings. For easy understanding, XYZ coordinates orthogonal to each other are set and appropriately referred to. As shown in fig. 1, the + Y direction in the Y-axis direction of the XYZ coordinates is the same direction as the insertion direction D1 in which the connection object 90 is inserted into the body portion 10 of the terminal 1. The X-axis direction is the same direction as the width direction D3 of the terminal 1 or the object 90 to be connected thereto. The Z-axis direction is a direction orthogonal to the X-axis direction and the Y-axis direction.
The terminal 1 is used as an electronic circuit component mounted on an automobile component, for example, and is used for connecting an object 90 to be connected to a cable 80 as shown in fig. 1. The terminal 1 is formed by bending a single plate-shaped member formed of a conductive material. The plate-like member is formed of a conductive material such as copper or a copper alloy. However, the terminal 1 is not limited to this, and may be formed by combining a plurality of plate-like members.
In the present embodiment, the connection object 90 is, for example, a flat cable formed in a flat shape. The connection object 90 has a film-shaped base portion 90a formed of a resin material, and a paste portion 91 in which a conductive material is printed on the surface of the base portion 90a on the + Z side. The base 90a is formed of, for example, a polycarbonate material. The paste portion 91 is made of, for example, silver. The paste portion 91 is not printed near the side end portions on both sides in the width direction D3 (the end portion on the + X side and the end portion on the-X side) on the surface on the + Z side of the base portion 90 a. In this portion, the surface of the base 90a is exposed to the + Z direction. Thus, a paste portion 91 on which the conductive material is printed and a non-printed portion 92 on which the conductive material is not printed are formed on the surface of the base portion 90a on the + Z side. The base 90a and the paste 91 are made of any material. The base portion 90a may be formed of a material other than polycarbonate, and the paste portion 91 may be formed of a material other than silver. In the present embodiment, the connection object 90 is configured as a flat cable. However, it is not limited thereto. The connection object 90 may be made of a material other than a flat cable. For example, the connection object 90 may be a flexible printed circuit board or another common cable.
As shown in fig. 1 and 2, the terminal 1 includes a main body portion 10, an elastic plate 20, a base portion 30, a pressing portion 40, a 1 st protruding portion 50 (restricting portion), and a folded-back portion 60.
An opening 10a into which the connection object 90 is inserted is formed in the main body 10 so as to open in the-Y direction. The main body 10 is formed in a cylindrical shape in which the connection object 90 can be inserted from the opening 10a in the insertion direction D1 (+ Y direction), and the main body 10 extends in the insertion direction D1 or the Y axis direction. In the present embodiment, the main body 10 is formed in a quadrangular cylindrical shape having a rectangular XZ cross section with the width direction D3 as the longitudinal direction. As shown in fig. 3A and 3B, the body 10 is formed with a bottom wall 11 on which the connection object 90 is disposed.
As shown in fig. 3A, 3B, and 4, at least a part of the elastic plate 20 is disposed inside the main body 10 and extends in the insertion direction D1 or the Y-axis direction. Specifically, the tip end 20a and the base end 20b of the elastic plate 20 are exposed from the main body portion 10 and the elastic plate 20 is disposed inside the main body portion 10. Therefore, the distal end 20a of the elastic plate 20 is disposed on the depth side in the insertion direction D1 with respect to the inside of the main body 10, and the proximal end 20b of the elastic plate 20 is disposed on the front side in the insertion direction D1 with respect to the inside of the main body 10. The elastic plate 20 has a contact portion 21 that contacts the connection object 90. The connection object 90 is disposed between the elastic plate 20 and the bottom wall 11 so as to be pressed in the-Z direction by the contact portion 21.
As shown in fig. 4 and 5, the elastic plate 20 is provided with a slit 22 to form a contact portion 21. For example, a slit for forming the slit 22 is formed in the elastic plate 20. Then, the cut-out elastic plate 20 is partially expanded in the bending direction D5, so that the contact portion 21 is formed in a cantilever shape having an end portion on the + Y side as a free end. The contact portion 21 has an arch shape protruding in the-Z direction. The apex of the arch portion of the contact portion 21 is configured as a contact point which electrically contacts the connection object 90 when the connection object 90 is inserted into the body 10. In the present embodiment, as shown in fig. 4, two contact portions 21 are provided in the elastic plate 20. However, the number of the contact portions 21 of the elastic plate 20 is not limited to this, and may be changed as appropriate according to the application of the terminal 1 and the shape of the main body portion 10. For example, the elastic plate 20 may be provided with 1 contact portion 21, or may be provided with 3 or more contact portions 21.
As shown in fig. 6 and 7, the elastic plate 20 is formed with the 2 nd projecting portions 23R and 23L and the linear projecting portion 24.
The 2 nd protrusions 23R and 23L are formed at both ends (end on the + X side and end on the-X side) in the width direction D3 of the elastic plate 20 corresponding to the width direction D3 of the connection object 90. The 2 nd projecting portions 23R and 23L project from both ends of the elastic plate 20 in the width direction D3 and then are bent around the Y axis as the center axis, so as to project toward the connection object 90 inserted into the body 10. Specifically, the 2 nd projecting portions 23R and 23L are provided to project toward the non-printed portion 92 of the connection object 90 inserted into the main body portion 10. Further, the 2 nd protrusions 23R, 23L are provided extending in the Y axis direction along both ends in the width direction D3 of the elastic plate 20.
The linear protrusion 24 is formed to increase the rigidity of the elastic plate 20 formed to be relatively long in the width direction D3. The linear protrusion 24 protrudes in the + Z direction on the surface of the elastic plate 20 on the + Z side, and extends in the Y axis direction at the center of the elastic plate 20 in the width direction D3. The linear protrusion 24 is formed between the pair of contact portions 21.
As shown in fig. 3A, 3B, and 4, the base portion 30 is a portion between the contact portion 21 and the base portion 30, and the object to be connected 90 is sandwiched between the contact portion 21 and the base portion 30. In the present embodiment, the bottom wall portion 11 of the main body 10 is formed as a part of the base portion 30. However, it is not limited thereto. The bottom wall portion 11 of the main body 10 may be independent of the base 30. As shown in fig. 2 and 4, the base portion 30 is formed in a tapered shape in which the dimension in the width direction D3 gradually decreases in the + Y direction. A conductor crimping portion 32 and a cover fixing portion 33 are formed at the end portion of the base portion 30 on the + Y side. The conductor crimping portion 32 is crimped to and electrically connected to the conductive core wire of the cable 80. The cover fixing portion 33 presses the end of the insulating cover of the cable 80 by crimping, thereby protecting the connection between the conductor crimping portion 32 and the core wire from the pulling force.
In addition, the base portion 30 is formed with a conductor crimping portion 32 and a cover fixing portion 33, and also with a locking portion 31 as shown in fig. 8A and 8B.
The engagement portion 31 is provided to limit the position of the connection object 90 in the insertion direction D1 or the Y-axis direction with respect to the base portion 30, and to engage with the connection object 90. The locking portion 31 is formed by, for example, cutting a slit corresponding to the shape of the locking portion 31 in the base portion 30, and is formed in a cantilever shape by pulling up the cut portion from the slit. In the present embodiment, the locking portion 31 is locked to the edge of a locked hole 93 formed in the object to be connected 90 and penetrating in the Z-axis direction. Since the position of the object to be connected 90 relative to the base 30 can be limited by locking the locking portion 31 to the edge of the locked hole 93, the efficiency of the operation of connecting the object to be connected 90 to the terminal 1 can be improved.
As shown in fig. 1, 3A and 3B, the pressing portion 40 is bent by a jig or the like to press the distal end 20a of the elastic plate 20 in the direction of the base portion 30. As a result, push unit 40 bends elastic plate 20 with base end 20b as a base point, and as a result, contact portion 21 of elastic plate 20 is brought into contact with object 90 to be connected, thereby electrically connecting elastic plate 20 and object 90 to be connected. In the present embodiment, the pressing portions 40 are provided at 1 each of both ends (end portion on the + X side and end portion on the-X side) of the base portion 30 in the width direction D3, and the total number is two. However, it is not limited thereto. The number of the pressing portions 40 may be only 1, or 3 or more. However, in the present embodiment, the object 90 to be connected is a flat cable, and from the viewpoint of stably fixing the object 90 to the base 30, it is preferable that 1 pressing portion 40 is provided at each of both end portions (end portion on the + X side and end portion on the-X side) in the width direction D3 of the base 30. The pressing portion 40 is provided at a position not overlapping with the formation position of the slit 22 in the insertion direction D1. Specifically, the pressing portion 40 is provided on the depth side (on the + Y side) in the insertion direction D1 with respect to the formation position of the slit 22 in the elastic plate 20.
The 1 st protruding portion 50 is for holding the distal end 20a of the elastic plate 20 pressed by the pressing portion 40 in a non-contact state with respect to the base portion 30 at a position corresponding to the distal end 20a. Thus, the 1 st projecting portion 50 functions as a restricting portion that restricts the movement of the distal end 20a in the pressing direction D2. In the present embodiment, the 1 st protruding portion 50 is formed by cutting a slit 50a corresponding to the shape of the 1 st protruding portion 50 in the base portion 30. Then, the 1 st projecting portion 50 is formed to project in the + Z direction by bending the cut-out portion from the slit 50a substantially at right angles to the bending direction D4 in fig. 9A and 9B. However, it is not limited thereto. The 1 st protruding portion 50 may be formed separately from the base portion 30 and fixed to the base portion 30 by bonding or the like, for example. However, from the viewpoint of suppressing the manufacturing cost in the manufacturing process of the terminal 1, the 1 st protruding portion 50 is preferably formed by partially cutting and raising the base portion 30. As shown in fig. 9A and 9B, the 1 st projecting portion 50 is formed so that the length in the Z axis direction, that is, the projecting amount is larger than the length in the pressing direction D2 of the connection object 90, that is, the thickness.
As shown in fig. 1, 3A, and 3B, the folded portion 60 is provided at a base end 20B of the elastic plate 20 located on the front side (on the-Y side) in the insertion direction D1, and is folded back toward the opening 10 a. The folded-back portion 60 is a portion connecting the main body portion 10 and the elastic plate 20. Thereby, the elastic sheet 20 is connected to the main body 10 via the folded-back portion 60. In the present embodiment, the folded-back portion 60 has a dome portion with rounded corners. However, it is not limited thereto. The folded-back portion 60 may not have a rounded shape. Further, a gap 61 is partially formed in the folded-back portion 60, and the gap 61 is used to facilitate bending for forming the folded-back portion 60.
As described above, in the terminal 1 of the present embodiment, as shown in fig. 1, 3A and 3B, the 1 st projecting portion 50 holds the distal end 20a of the elastic plate 20 pressed by the pressing portion 40 in a non-contact state with respect to the base portion 30 at a position corresponding to the distal end 20a. The 1 st projecting portion 50 functions as a restricting portion that restricts movement of the distal end 20a in the pressing direction D2 by a predetermined degree or more. Therefore, the 1 st projecting portion 50 can suppress the pressing force from being applied from the pressing portion 40 to the object to be connected 90 sandwiched between the base portion 30 and the contact portion 21 via the distal end 20a of the elastic plate 20. Thus, the terminal 1 of the present embodiment can suppress degradation of the base portion 90a due to hydrolysis, as compared with a case where a pressing force is applied to the connection object 90. Further, the terminal 1 of the present embodiment can suppress breakage of the base portion 90a caused by continuous application of a pressing force to the connection object 90. As described above, the terminal 1 of the present embodiment can suppress damage to the connection object 90.
In the present embodiment, as shown in fig. 3A, 3B, 9A, and 9B, the 1 st projecting portion 50 is formed so that the length in the Z axis direction, that is, the projecting amount is larger than the length in the pressing direction D2 of the object to be connected 90, that is, the thickness. Therefore, the 1 st projecting portion 50 can reliably restrict the pressing of the pressing portion 40 against the distal end 20a of the elastic plate 20. Further, the 1 st projecting portion 50 can suppress the pressing force from being applied from the pressing portion 40 to the connection object 90 sandwiched between the base portion 30 and the contact portion 21 via the distal end 20a of the elastic plate 20. Thus, the terminal 1 of the present embodiment can suppress damage to the connection object 90.
As shown in fig. 1, 3A and 3B, the terminal 1 of the present embodiment includes a folded-back portion 60, and the folded-back portion 60 has an arch portion with rounded corners. Therefore, for example, when a force is applied from the outside and the connection object 90 is rolled up from the base 30, it is possible to suppress a situation in which the rolled-up portion interferes with the terminal 1. Specifically, in the case of a terminal having no folded portion 60, there is a possibility that a portion folded up from the base 30 interferes with the top wall portion 12 of the body 10 of the terminal 1. When the portion rolled up from the base 30 interferes with the top wall portion 12, the paste portion 91 of the object 90 may be peeled or abraded by the corner portion of the top wall portion 12, and as a result, the object 90 may be damaged. In contrast, the terminal 1 includes a folded-back portion 60 having an arch portion. Thus, even when the connection object 90 is rolled up from the base 30, the terminal 1 can suppress the connection object 90 from being damaged such as peeling or abrasion of the paste portion 91 of the connection object 90 by the round shape of the arch portion.
In the terminal 1 of the present embodiment, as shown in fig. 3A and 3B, the pressing portion 40 is provided at a position not overlapping with the formation position of the slit 22 in the insertion direction D1. Therefore, the pressing portion 40 can reliably press the distal end 20a of the elastic plate 20, which is a portion where the slit 22 is not formed. This enables the 1 st projecting portion 50 to reliably restrict the pressing of the pressing portion 40 against the distal end 20a of the elastic plate 20. Further, the 1 st projecting portion 50 can suppress the pressing force from the pressing portion 40 to the object 90 to be connected sandwiched between the base portion 30 and the contact portion 21 via the distal end 20a of the elastic plate 20. As a result, the terminal 1 of the present embodiment can suppress the breakage of the connection object 90.
In the terminal 1 of the present embodiment, as shown in fig. 6 and 7, the 2 nd projecting portions 23R and 23L are formed at both ends in the width direction D3 of the elastic plate 20 corresponding to the width direction D3 of the connection object 90, and the 2 nd projecting portions 23R and 23L project toward the non-printed portion 92 of the connection object 90 inserted into the body portion 10. Therefore, the object 90 to be connected can be prevented from rolling up from the base 30. Even when the connection object 90 is rolled up from the base 30, the 2 nd projecting portions 23R and 23L do not interfere with the paste portion 91 but interfere with the non-printed portion 92 of the connection object 90, and therefore, damage to the connection object 90 can be suppressed.
The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments.
For example, in the embodiment of the present invention, as shown in fig. 3A and 3B, the 1 st protruding portion 50 functioning as the restricting portion protrudes from the base portion 30 toward the distal end 20a of the elastic plate 20. However, it is not limited thereto. The 1 st projecting portion 50 may have a shape other than the projecting shape as long as it can hold the distal end 20a of the elastic plate 20 in a non-contact state with respect to the base 30.
In the embodiment of the present invention, as shown in fig. 3A, 3B, 9A, and 9B, the projecting amount of the 1 st projecting portion 50 is larger than the length of the object to be connected 90 in the pressing direction D2. However, it is not limited thereto. For example, the projecting amount of the 1 st projecting portion 50 may be equal to the length of the object to be connected 90 in the pressing direction D2. In this case, the 1 st projecting portion 50 can suppress the pressing force from being applied from the pressing portion 40 to the connection object 90 sandwiched between the base portion 30 and the contact portion 21. Thus, the terminal 1 of the present embodiment can suppress damage to the connection object 90. However, from the viewpoint of reliably suppressing the pressing force from the pressing portion 40 from being applied to the object to be connected 90, it is preferable that the protruding amount of the 1 st protruding portion 50 is larger than the length of the object to be connected 90 in the pressing direction D2 as in the embodiment of the present invention.
As shown in fig. 1, 3A and 3B, the terminal 1 according to the embodiment of the present invention includes a folded portion 60, and the elastic plate 20 is connected to the main body 10 via the folded portion 60. Thereby, the elastic plate 20 is integrally formed with the main body 10. However, it is not limited thereto. For example, the folded-back portion 60 may not be provided and the elastic plate 20 may be formed separately from the main body 10.
In the embodiment of the present invention, as shown in fig. 3A, 3B, and 4, the slit 22 is cut in the elastic plate 20, and the cut portion is pulled up from the slit 22, whereby the contact portion 21 is formed in a cantilever shape. However, it is not limited thereto. The contact portion 21 may be formed in a simple beam shape. However, from the viewpoint of ease of manufacture, the contact portion 21 is preferably formed in a cantilever shape. In addition, the contact portion 21 is also preferably formed in a cantilever shape from the viewpoint of ensuring the elastic force and the flexibility of the contact portion 21 and the electrical connection capability to the connection object 90.
In the embodiment of the present invention, as shown in fig. 1, non-printed portions 92 on which the conductive material is not printed are formed in the vicinity of the side end portions on both sides in the width direction D3 of the connection object 90 to which the terminal 1 is connected, and a paste portion 91 is formed between the non-printed portions 92. However, the object to be connected to the terminal 1 is not limited to the shape and the specification of the object to be connected 90. For example, like the connection object 90-2 shown in fig. 10, a flat cable may be used in which the non-printed portion 94 is formed between the two paste portions 91 and is longer than the connection object 90 in the width direction D3. The object 90-2 to be connected is connected to two terminals 1.
The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the invention. The above embodiments are illustrative of the present invention and do not limit the scope of the present invention.
