Description

The present invention relates to a chain terminal in which a plurality of terminals to which electric wires are connected are connected.

As the terminal to which the electric wire is connected, there is one disclosed in Patent Document 1 below. This terminal has an electric wire connecting portion for connecting an electric wire on one side in the longitudinal direction, and has a terminal connecting portion for connecting another terminal on the other side. Of these, the electric wire connecting portion has a square tubular shape with one end open, and an electric wire pressing piece is formed on a part of the upper surface that becomes an upper surface when mounted on the housing. The electric wire pressing piece has elasticity, and the free end side portion is bent into a substantially triangular shape in the side view. Further, the electric wire pressing piece projects outward from the upper surface of the electric wire connecting portion.

In the electric wire connecting portion having such a configuration, the electric wires are connected as follows. First, the tip of the electric wire with the exposed core wire is inserted through the opening at one end. After that, the electric wire pressing piece is pressed from above and deformed. The free end portion of the deformed electric wire pressing piece presses the electric wire from above to electrically connect the electric wire and mechanically fix the electric wire.

JP-A-2019-61743

The electric wire pressing piece protruding outward is formed on the upper surface of the electric wire connecting portion as described above. For this reason, even in the chain terminal in which a plurality of terminals are arranged side by side on the side portion of the band-shaped carrier, the surface having the electric wire pressing piece naturally faces the upper surface, that is, the direction perpendicular to the surface of the carrier. In other words, the vertical direction of the terminal is considered based on the posture of being mounted on the housing. It is technically normal that the vertical direction of the housing and the vertical direction of the terminal are set to be the same, and even in the terminal of the chain terminal, the vertical direction of the terminal is the direction perpendicular to the surface of the carrier.

However, as described above, if the electric wire pressing piece is oriented in the direction perpendicular to the surface of the carrier, there is a high possibility that the electric wire pressing piece will be deformed.

For example, chain terminals are handled by being wound on a reel after manufacturing. In the chain terminals wound on the reel, the terminals facing upward are layered in the radial direction of the reel. Interlayer paper is stacked on the chain terminals, and there is an interlayer paper between the terminals that overlap in the radial direction. However, especially in the terminal where the electric wire pressing piece protrudes outward, the electric wire pressing piece is loaded from above.

If the load continues to be applied, the wire pressing piece may be deformed even though it has elasticity. If the electric wire pressing piece is deformed, the electric wire insertion work may not be smooth or impossible, and the electric wire connection may be hindered.

In addition, the wire pressing piece has a risk of deformation even before it is wound on a reel. For example, the chain terminals are manufactured in a press and then transported along the longitudinal direction of the carrier. Peripheral parts such as guide materials for guiding chain terminals are present in the transport path. Therefore, the electric wire pressing piece facing the direction perpendicular to the surface of the carrier is more likely to come into contact with the peripheral member.

Even if the terminal does not project outward, if the terminal is displaced relative to the carrier, the deformable wire pressing piece is likely to be loaded, and the wire pressing piece may be deformed.

Therefore, it is a main object of the present invention to prevent deformation of the electric wire pressing piece so that the electric wire and the terminal can be connected as desired.

The means for this is a chain terminal having a band-shaped carrier and terminals having one end continuous in the longitudinal direction on the side portion of the carrier, and a plurality of the terminals arranged side by side at a constant pitch along the longitudinal direction of the carrier. A wire pressing piece is formed on the outer surface around the axis of the terminal to press and connect the inserted electric wire by deformation, and the deformation direction of the wire pressing piece is on the surface of the carrier. A chain terminal that is oriented horizontally with respect to the vertical direction.

In this configuration, the wire pressing piece of the terminal is formed in a direction perpendicular to the surface of the carrier, that is, a surface in a direction of lying down with respect to the vertical direction. When handling such as when the chain terminal is wound on a reel, even if the terminals having the electric wire pressing pieces facing sideways overlap each other in the vertical direction, it is possible to prevent the electric wire pressing piece from receiving an external force. Further, since the terminals are separately arranged along the longitudinal direction of the carrier, there is a space at the tip of the wire pressing piece facing sideways. Therefore, it is possible to prevent the electric wire pressing piece from coming into contact with other terminals in the lateral direction and receiving an external force. In this way, deformation of the wire pressing piece is prevented.

As an aspect of the present invention, the electric wire pressing piece may be formed on a surface of the terminal facing upward when the terminal is mounted on the housing.

In this configuration, not only the wire pressing piece, but the upper surface of the entire terminal faces sideways. Since the upper surface or the lower surface of the terminal may require a structure such as a convex portion such as locking or positioning used for locking to the housing, such a structure can also be protected from a load due to an external force. Therefore, the terminal can be securely attached to the housing, and the electric wire can be connected as desired by the electric wire pressing piece in combination with the prevention of unexpected deformation of the electric wire pressing piece.

As an aspect of the present invention, the terminal has an electric wire connecting portion for connecting an electric wire and a terminal connecting portion for connecting to another terminal in this order from the carrier side, and the electric wire pressing piece is the electric wire connecting portion. It may be a structure formed in.

In this configuration, the wire pressing piece is formed at the wire connection portion located on the carrier side. Therefore, the amount of displacement in which the portion having the electric wire pressing piece swings in the longitudinal direction of the carrier is smaller than that in the case of being formed in the terminal connection portion away from the carrier, and the possibility that the electric wire pressing piece receives an unnecessary external force can be reduced. .. This also prevents unexpected deformation of the electric wire pressing piece, so that the electric wire can be connected as desired by the electric wire pressing piece.

As an aspect of the present invention, the electric wire pressing piece may project outward, and the protruding height of the electric wire pressing piece may be lower than the pitch at which the terminals are arranged side by side.

In this configuration, even if the wire pressing piece projects laterally, the protrusion height is lower than the parallel pitch of the terminals, so that the wire pressing piece is prevented from strongly hitting the adjacent terminal. By more reliably preventing unexpected deformation of the electric wire pressing piece, it is possible to secure the desired electric wire connection.

As an aspect of the present invention, the width of the electric wire pressing piece may be shorter than the width of the terminal of the portion having the electric wire pressing piece.

In this configuration, even if the terminals overlap in the vertical direction during handling such as when the chain terminals are wound on a reel, it is possible to prevent the electric wire pressing pieces from hitting each other in the vertical direction at the terminals arranged vertically. By more reliably preventing unexpected deformation of the electric wire pressing piece, it is possible to secure the desired electric wire connection.

As an aspect of the present invention, the terminal may have a protrusion protruding in a direction perpendicular to the surface of the carrier.

According to this configuration, the protrusion, whether it is a part for engaging with a housing or other member, or simply a protruding structure, is present when the chain terminal is wound on a reel. Keep the distance between the terminals that are lined up and down when handling such as. By more reliably preventing unexpected deformation of the electric wire pressing piece, it is possible to secure the desired electric wire connection.

Another means for solving the problem is a reel-wound chain terminal in which the carrier of the above-mentioned chain terminal is wound on a reel with the deformation direction of the electric wire pressing piece directed in the circumferential direction.

The reel-wound chain terminal having this configuration prevents unexpected deformation of the wire pressing pieces of the terminals overlapping in the vertical direction as described above. Therefore, even if the chain terminal wound on the reel is packed or transported violently, the electric wire pressing piece can exert the desired function when connecting the electric wire.

Another means for solving the problem is to have a housing to which the terminal of the chain terminal described above is mounted, and the surface direction of the cut end portion formed when the terminal is separated from the carrier is the upper and lower sides of the housing. It is a connector along the direction.

In the connector having this configuration, the surface direction of the cut end portion of the terminal and the deformation direction of the electric wire pressing piece that is deformed due to the electric wire connection at the terminal are the same. Since the cut end portion increases the strength of the shape of the portion where the electric wire pressing piece is formed in the surface direction, the electric wire pressing piece can be deformed as desired. Therefore, when the electric wire is connected by the electric wire pressing piece which prevents unexpected deformation as described above, the terminal can exhibit the desired function.

As described above, according to the present invention, since the electric wire pressing piece is not subjected to an external force, the electric wire pressing piece can be prevented from being deformed before use, and the electric wire and the terminal can be connected as desired.

An embodiment for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of the chain terminal 11. The chain terminal 11 is formed by connecting a plurality of terminals 13 via a carrier 15 and is composed of one conductive metal plate. As shown in FIG. 2, such a chain terminal 11 is wound around a reel 17 and is handled for packing, transportation, and the like. In FIG. 2, reference numeral 19 denotes an interlayer paper, which is arranged along the longitudinal direction of the carrier 15 of the chain terminal 11 and is inserted between different layers of the chain terminals 11 stacked in a roll shape.

The carrier 15 that connects the plurality of terminals 13 is a long strip having a predetermined width. The carrier 15 is formed with a through hole 51 necessary for transportation and the like.

As shown in FIG. 3, the terminal 13 is formed in a rod shape as a whole, and has an electric wire connecting portion 31 for connecting the electric wire 21 (see FIG. 8) and a terminal connecting portion 32 for connecting to other terminals. ing. That is, the electric wire connecting portion 31 is provided on one end side in the longitudinal direction, and the terminal connecting portion 32 is provided on the other end side. The illustrated terminal 13 is an example, and may have a configuration in which a portion having another function exists between the electric wire connecting portion 31 and the terminal connecting portion 32.

The terminal 13 shown in FIG. 1 is a female terminal 13a among male and female terminals, and the terminal connection portion 32 of the female terminal 13a is electrically inserted with the terminal connection portion 32 of the male terminal 13b shown in FIG. This is the part to be connected. The shapes of the terminal connection portions 32 of the female terminal 13a and the male terminal 13b are different, but the structure of the electric wire connection portion 31 is the same.

One end of the terminal 13 is continuous with one side of the carrier 15 in the longitudinal direction, and a plurality of terminals 13 are arranged side by side at a constant pitch along the longitudinal direction of the carrier 15. Of the electric wire connecting portion 31 and the terminal connecting portion 32, the electric wire connecting portion 31 is connected to the carrier 15. The electric wire connecting portion 31 is connected via a narrow connecting portion 52 protruding from the side portion of the carrier 15. That is, the terminal 13 has an electric wire connecting portion 31 for connecting the electric wire 21 and a terminal connecting portion 32 for connecting to other terminals in this order from the carrier 15 side.

The structure of the electric wire connecting portion 31 at the terminal 13 will be described below by taking the female terminal 13a as an example.

The electric wire connecting portion 31 is formed in a hollow shape into which the electric wire 21 can be inserted. The electric wire connecting portion 31 in the illustrated example has a square tubular shape. The female terminal 13a has a substantially square tubular shape as a whole including a portion other than the electric wire connecting portion 31. The electric wire connecting portion 31 may have a square cylinder shape, or may have another shape such as a cylindrical shape or a polygonal tubular shape.

The electric wire connecting portion 31 of the terminal 13 has an electric wire pressing piece 33 that presses and connects the electric wire 21 inserted by being deformed to the outer surface around the shaft. The electric wire pressing piece 33 is formed by cutting up on the upper surface 34a and the lower surface 34b, which are the outer surfaces around the shaft, and the upper surface 34a of the left and right side surfaces 34c. The electric wire pressing piece 33 projects outward and is elastically deformable.

The above-mentioned "upper surface 34a" is an upper surface for the terminal 13, and is different from the upper surface of the chain terminal 11 having the carrier 15 (vertically above the surface of the carrier 15). The "upper surface 34a" is a surface facing upward or downward of the housing when mounted on the housing. The "lower surface 34b" is a surface opposite to the upper surface 34a, and like the upper surface 34a, faces upward or downward of the housing when mounted on the housing. The "side surface 34c" is a surface connecting the upper surface 34a and the lower surface 34b, and when mounted on the housing, faces in the left-right direction of the housing. Further, the expressions such as the upper surface 34a indicate the direction for explanation, and are not related to the direction when the product is mounted.

Since the electric wire pressing piece 33 is formed in the electric wire connecting portion 31, it is formed in a portion of the terminal 13 on the side closer to the carrier 15.

The electric wire pressing piece 33 has a front inclined surface 33a, a rear inclined surface 33b, and a rear end curved portion 33c. The front inclined surface 33a is inclined rearward and diagonally upward from the end side of the electric wire connecting portion 31, which is also the end of the terminal 13. The rear inclined surface 33b extends downward from the upper end of the front inclined surface 33a. The rear end curved portion 33c is a bent portion at the lower end of the rear inclined surface 33b, and the tip of the rear end curved portion 33c faces diagonally upward forward, which is the lower surface side of the front inclined surface 33a. The width from the front inclined surface 33a to the rear end curved portion 33c is the same.

In addition to such an electric wire pressing piece 33, a locking projection 35 for fixing to the housing and a positioning portion 36 are formed on the upper surface 34a of the terminal 13.

The locking projection 35 is elastically deformable and projects in a triangular shape in a side view on the upper surface of the intermediate portion in the longitudinal direction of the terminal 13. The protruding height of the locking projection 35 is lower than the protruding height H of the electric wire pressing piece 33. The width of the locking projection 35 is the same throughout the longitudinal direction.

The positioning portion 36 is formed by bending a portion having an appropriate length from the end portion of the terminal connecting portion 32 so as to project upward in a region substantially half of the width direction of the upper surface. The height of the positioning portion 36 is higher than the height of the locking projection 35, but is a height that fits within the wall thickness of the corresponding portion of the housing.

Such a female terminal 13a constitutes the female connector 22 shown in FIG. The female connector 22 has a female outer member 23, a female inner member 24 as the housing described above fitted to the female outer member 23, and a female terminal 13a. The female terminal 13a is connected to the electric wire 21 inside the female inner member 24.

The functions of the electric wire pressing piece 33, the locking projection 35, and the positioning portion 36 of the female terminal 13a described above will be described below while showing the connection mode of the electric wire 21.

FIG. 6 is a perspective view showing the female inner member 24, the electric wire 21, and the female terminal 13a, and FIG. 7 is a cross-sectional view showing a portion of the female inner member 24 into which the electric wire 21 and the female terminal 13a are inserted.

The portion of the female inner member 24 into which the electric wire 21 is inserted (hereinafter, referred to as “electric wire insertion portion 25”) is composed of a hole having an appropriate length and a circular cross section. The tip portion of the hole portion has a reduced diameter portion 25a whose diameter becomes smaller toward the tip side and a small diameter portion 25b through which the core wire 21a of the electric wire 21 passes.

The portion of the female inner member 24 into which the female terminal 13a is inserted (hereinafter referred to as "terminal insertion portion 26") is continuously formed at the tip of the small diameter portion 25b of the electric wire insertion portion 25, and has a cross-sectional shape of the female terminal. It is a substantially quadrangular cross section into which 13a can be inserted. The length of the terminal insertion portion 26 corresponds to the length of the female terminal 13a.

The electric wire insertion portion 25 and the terminal insertion portion 26 of the female inner member 24 are formed in two upper and lower stages in the thickness direction except for a part of the female inner member 24. The upper and lower wire insertion portions 25 and terminal insertion portions 26 have a shape in which the terminals 13 are inserted upside down, respectively. That is, the upper terminal insertion portion 26 has a surface corresponding to the upper surface 24a of the female inner member 24, which is a surface facing upward of the housing, as the upper surface. Further, the lower terminal insertion portion 26 has a surface corresponding to the lower surface 24b of the female inner member 24, which is a surface facing downward of the housing, as the upper surface.

The representations of the upper surface and the lower surface of the housing (female inner member 24) also indicate directions for explanation, and are not related to the directions when the housing (female inner member 24) is mounted in the product.

When the female terminal 13a inserted into the terminal insertion portion 26 is mounted on the female inner member 24 which is a housing, an electric wire pressing piece 33 is formed on a surface facing upward or downward of the female inner member 24. Will be there.

On the upper surface of the upper and lower terminal insertion portions 26, that is, the upper surface 24a and the lower surface 24b of the female inner member 24, a pressing piece through hole 27 into which the electric wire pressing piece 33 of the female terminal 13a is fitted and a locking projection 35 are fitted. A protrusion through hole 28 and a notch 29 in which the positioning portion 36 is accommodated are formed.

The pressing piece through hole 27 is formed at a position where the female terminal 13a is fitted when the female terminal 13a is halfway inserted into the terminal insertion portion 26. Specifically, the pressing piece through hole 27 is formed at a position corresponding to the electric wire pressing piece 33 with the positioning portion 36 protruding from the terminal inserting portion 26.

A front-stage locking hole 28a as one of the above-mentioned locking projection through holes 28 is formed at a position corresponding to the locking projection 35 in a state where the electric wire pressing piece 33 is fitted in the pressing piece through hole 27. ..

Between the front-stage locking hole 28a and the pressing piece through hole 27, when the female terminal 13a is pushed all the way into the terminal insertion portion 26, the position corresponding to the locking projection 35 is the above-mentioned locking projection penetration. A rear locking hole 28b is formed as one of the holes 28.

The notch portion 29 is formed over a length range corresponding to the positioning portion 36 from the rear end of the terminal insertion portion 26. The upper surface of the portion in front of the cutout portion 29 has an inclined surface 24c that is lowered toward the rear end.

The electric wire 21 is connected to the female terminal 13a by inserting the electric wire 21 and the terminal 13 from opposite directions of the female inner member 24 as shown in FIG. First, the female terminal 13a inserted earlier is held in front of the female terminal 13a without being inserted all the way (see (a) in FIG. 8). That is, the electric wire pressing piece 33 is fitted into the pressing piece through hole 27. Next, the core wire 21a of the electric wire 21 inserted into the electric wire insertion portion 25 is inserted into the axial center portion of the electric wire insertion portion 25 of the female terminal 13a (see (b) of FIG. 8). After that, when the female terminal 13a is pushed all the way into the terminal insertion portion 26, the electric wire pressing piece 33 is deformed to press the electric wire 21, electrically connect the electric wire 21, and mechanically fix the electric wire 21. ..

The female terminal 13a having the electric wire pressing piece 33, the locking projection 35, and the positioning portion 36 that fulfills such a function is formed so as to have the following relationship with the carrier 15. That is, as shown in FIG. 1, the deformation direction D1 of the electric wire pressing piece 33 is lateral to the direction D2 perpendicular to the surface of the carrier 15. In other words, the upper surface 34a of the terminal 13 is turned sideways. The sideways angle does not matter.

The dimensions of the electric wire pressing piece 33 will be described as shown in FIG. That is, the electric wire pressing piece 33 projects outward as described above, and the protruding height H of the electric wire pressing piece 33 is lower than the pitch P in which the terminals 13 are arranged side by side. Furthermore, the protruding height H of the electric wire pressing piece 33 is shorter than the distance L between the adjacent terminals 13. Further, the width W1 of the electric wire pressing piece 33 is shorter than the width W2 of the terminal 13 of the portion having the electric wire pressing piece 33.

The chain terminal 11 having the male terminal 13b is shown in FIG. 10 which is a plan view for reference. As shown in this figure, the electric wire connecting portion 31 of the male terminal 13b has the same configuration as the electric wire connecting portion 31 of the female terminal 13a.

The chain terminal 11 having the above configuration is manufactured by a press machine (not shown) and then conveyed, and as shown in FIG. 2, the carrier 15 directs the deformation direction D1 of the electric wire pressing piece 33 in the circumferential direction. It is wound on a reel 17. The chain terminal 11 wound around the reel 17 is packed, transported, and handled for use as a reel-wound chain terminal.

The female terminal 13a of the chain terminal 11 is separated from the carrier 15 and mounted in the female inner member 24 while being connected to the electric wire 21 as shown in FIGS. 6 and 8 as described above.

When the female terminal 13a is separated from the carrier 15, as shown in FIG. 3, a cut end portion 37 in which a part of the cut connecting portion 52 remains is formed at the end of the female terminal 13a. Since the female terminal 13a is connected in a rollover posture with respect to the direction D2 perpendicular to the surface of the carrier 15, when the female terminal 13a is attached to the female inner member 24, the surface direction of the cut end portion 37 is the housing, that is, the female. It follows the vertical direction of the inner member 24. A female inner member 24 in which the cut end portion 37 extends in the vertical direction, and thus a female connector 22 is obtained. When the terminal 13 is a male terminal 13b, a male connector (not shown) is obtained.

As described above, the terminal 13 directs the deformation direction D1 of the electric wire pressing piece 33 laterally with respect to the direction D2 perpendicular to the surface of the carrier 15. Therefore, for example, it is possible to avoid contact with peripheral parts of the transport path during transport of the chain terminal 11. Further, even if the terminals 13 overlap each other in the vertical direction during handling such as when the reel-wound chain terminals are used, it is possible to prevent the electric wire pressing piece 33 from receiving an external force as shown in FIG. 11A.

On the other hand, as seen in FIG. 12 showing the chain terminal 110 of the comparative example, when the deformation direction of the electric wire pressing piece 330 is directed to the direction perpendicular to the plane of the carrier 150, FIG. 11B As shown by the virtual line, the electric wire pressing piece 330 is deformed downward by receiving an external force. In this case, the electric wire pressing piece 330 hinders the insertion of the electric wire at the time of connecting the electric wire, so that the electric wire cannot be connected as desired.

The fact that the load from the vertical direction can be avoided as described above is ensured by the width of the electric wire pressing piece 33 being shorter than the width of the terminal 13 of the portion having the electric wire pressing piece 33.

Further, the deformation direction D1 of the electric wire pressing piece 33 is directed toward the adjacent terminals 13, and the electric wire pressing piece 33 is protruding, but between the terminals 13 separated along the longitudinal direction of the carrier 15. Has space. Therefore, it is possible to prevent the electric wire pressing piece 33 from coming into contact with the other terminals 13 in the lateral direction and receiving an external force.

The fact that the load from the lateral direction can be avoided in this way is ensured by the fact that the protruding height of the wire pressing piece 33 is lower than the pitch P in which the terminals 13 are arranged side by side. In particular, since the protruding height H of the electric wire pressing piece 33 is shorter than the distance L between the adjacent terminals 13, even if the electric wire pressing piece 33 protrudes outward, it is more reliably avoided to receive the load from the lateral direction. it can.

In this way, the deformation of the electric wire pressing piece 33 is prevented. As a result, the electric wire pressing piece 33 can be prevented from being deformed, the terminal 13 can exhibit the desired function, and the electric wire 21 and the terminal 13 can be connected as desired. In particular, the terminal 13 has an electric wire pressing piece 33, and the electric wire pressing piece 33 can connect the electric wire 21 only by inserting the electric wire 21 and then deforming the terminal 13. For this connection, the accuracy of the shape of the electric wire pressing piece 33 is required, but since the electric wire pressing piece 33 is prevented from being unexpectedly deformed, it greatly contributes to the improvement of workability and the accuracy.

Since the electric wire pressing piece 33 is laterally oriented with respect to the carrier 15, and in particular, the entire terminal 13 is laterally oriented, the locking projection 35 and the positioning portion 36 other than the electric wire pressing piece 33 are also laterally oriented. Therefore, even if the electric wire pressing piece 33 or the like protrudes outward, the height in the state of being wound around the reel 17 can be lowered (see FIG. 11). As a result, the state of being wound around the reel 17 can be made compact, and the efficiency in handling can be improved.

Further, the electric wire pressing piece 33 is formed on the surface of the terminal 13 facing upward or downward of the housing when mounted on the housing. That is, the upper surface 34a for the entire terminal 13 faces sideways. Therefore, the parts such as the locking projection 35 and the positioning portion 36 are also prevented from receiving the load due to the vertical overlap of the chain terminals 11. As a result, the terminal 13 can be securely attached to the female inner member 24 as desired. That is, the connection of the electric wire 21 by the electric wire pressing piece 33 can be performed as desired, coupled with the prevention of unexpected deformation of the electric wire pressing piece 33.

The terminal 13 has the electric wire connecting portion 31 and the terminal connecting portion 32 in this order from the carrier 15 side, and since the electric wire pressing piece 33 is formed in the electric wire connecting portion 31, the portion having the electric wire pressing piece 33 is the carrier 15. The amount of displacement that swings in the longitudinal direction is small. That is, the distance between the adjacent terminals 13 can be secured, and the possibility that the electric wire pressing piece 33 receives an unnecessary external force can be reduced. This also prevents the electric wire pressing piece 33 from being unexpectedly deformed, and the electric wire 21 can be connected by the electric wire pressing piece 33 as desired.

In addition, in the connector to which the terminal 13 is mounted, that is, the female connector 22, the surface direction of the cut end portion 37 of the terminal 13 and the deformation direction D1 of the electric wire pressing piece 33 that is deformed due to the electric wire connection at the terminal 13 are It is the same. Since the cut end portion 37 increases the strength of the shape of the portion where the electric wire pressing piece 33 is formed in the plane direction thereof, the electric wire pressing piece 33 can be deformed as desired. Therefore, when the electric wire is connected by the electric wire pressing piece 33 which prevents unexpected deformation as described above, the terminal 13 can exhibit the desired function.

Other examples will be described below. In this description, the same parts as those described above are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 13 is a front view of the chain terminal 11 according to another example. This figure is a front view of the surface of the terminal 13 on which the electric wire pressing piece 33 is formed. As shown in this figure, protrusions 38 protruding in the direction D2 perpendicular to the surface of the carrier 15 are formed on the left and right side surfaces 34c of the terminal 13, that is, on both the upper and lower surfaces in the drawing. These protrusions 38 may be formed by bulging independently, in addition to projecting a part of the piece to be bent inward to the outside.

The protrusions 38 maintain an interval at the terminals 13 arranged vertically during handling such as when the chain terminals 11 are wound around the reel 17. Since unexpected deformation of the electric wire pressing piece 33 is more reliably prevented, the desired connection of the electric wire 21 can be ensured.

The above is one form of the configuration for carrying out the present invention, and the present invention is not limited to the above-mentioned configuration, and other configurations can be adopted.

For example, the electric wire pressing piece 33 does not have to protrude outward, and may be plastically deformed without having elasticity. Further, the above-mentioned deformation mode of the electric wire pressing piece 33 is an example, and may be configured to be deformed by another method.

The shape of the terminal 13 including the electric wire connecting portion 31 and the terminal connecting portion 32 is an example, and can be appropriately designed. The terminal 13 may be configured by combining a plurality of members.

The chain terminal 11 may have terminals 13 on both sides of the carrier 15.
