  1, 2, 3, 4, 5, 6, 7, and 8, a chain terminal 1 includes a plurality of terminals 2 that are applied to a connector 100 (see FIG. 11, etc.) and a terminal holder. By arranging and holding them in a chain by 3, the handling of each terminal 2 at the time of manufacturing the connector 100 or the like is facilitated and workability is improved.

  First, the connector 100 to which the terminal 2 of the chain terminal 1 is applied will be described with reference to FIGS. 11 and 12. The connector 100 includes a connector housing 101 and terminals 2 and constitutes a so-called wire-to-wire connection mechanism, wire-to-board connection mechanism, and the like. The connector 100 is a male connector that holds the terminal 2 in the connector housing 101 when the male terminal 2 is press-fitted into a plurality of press-fitting holes 102 formed in the connector housing (male housing) 101.

  The connector housing 101 is entirely made of an insulating synthetic resin material or the like. The connector housing 101 includes a hood portion 103 and a partition wall portion 104. The hood part 103 is formed in a substantially rectangular tube shape. The hood portion 103 has a hollow interior and is open at both ends in the cylindrical axial direction. The partition wall portion 104 is formed as a partition wall that closes the hollow interior of the hood portion 103 at an intermediate portion in the axial direction of the hood portion 103 (see also FIG. 5 and the like). The partition wall 104 partitions the space inside the hood 103 into a contact-side space 105 and a connection-side space 106 (see also FIG. 5 and the like). The contact side space portion 105 is a space portion that communicates with one opening of the hood portion 103, and a mating connector (female connector) that holds a mating terminal (female terminal) that is electrically connected to the terminal 2. It is a space part which the connector housing (female housing) 107 of this fits. The connection side space portion 106 is a space portion that communicates with the other opening of the hood portion 103, and is a space portion on the side where an electric wire, a substrate, or the like connected to the terminal 2 is located. The opening on the connection side space portion 106 side is covered together with each terminal 2 by a cover member or the like in a state where an electric wire, a board, or the like is connected to the terminal 2. In the connector housing 101, the partition wall 104 is provided close to the opening side of the connection side space 106 (see also FIG. 5 and the like). Accordingly, in the connector housing 101, the distance (depth) from the opening in the contact-side space 105 to the partition 104 is relatively longer (deep), and the distance from the opening in the connection-side space 106 to the partition 104 (Depth) is formed to be relatively short (shallow). In the connector housing 101, a plurality of press-fitting holes 102 are formed in the partition wall portion 104. The press-fitting hole 102 may be referred to as a cavity that holds the terminal 2. Each press-fitting hole 102 penetrates the partition wall 104 and communicates the contact-side space 105 and the connection-side space 106 (see also FIG. 5 and the like). Here, each press-fitting hole 102 is formed as a rectangular through hole. The press-fitting holes 102 are formed with a predetermined pitch and a predetermined number according to specifications, usage conditions, and the like required for a device to which the connector 100 is applied. Here, a total of 44 press-fitting holes 102 are formed in four stages, with 11 in a row (see FIG. 12 and the like).

  The terminal 2 is entirely composed of a conductive metal material or the like, and the surface thereof is subjected to conductive plating or the like. The terminal 2 is a wire rod terminal made of a rectangular wire rod formed in a rod shape. A plurality of terminals 2 are provided corresponding to the number of the plurality of press-fitting holes 102. Each terminal 2 is formed in a rectangular column shape corresponding to the shape of each press-fitting hole 102. That is, each terminal 2 has a rectangular cross-sectional shape in a direction orthogonal to the extending direction of the terminal 2 (hereinafter, also referred to as “terminal extending direction”). Each terminal 2 includes a contact portion 21, a connection portion 22, and a press-fit locking portion 23 as shown in FIG. 1 and the like. Each terminal 2 constitutes a contact portion 21 having one end portion in contact with a counterpart terminal, and the other end portion constitutes a connection portion 22 that is connected to and connected to an electric wire, a substrate, or the like. Each terminal 2 is formed with a press-fit locking portion 23 that is press-fitted into the press-fit hole 102 and locked between the contact portion 21 and the connection portion 22. The press-fit locking portion 23 is configured by, for example, a plurality of concave portions formed on the outer surface of each terminal 2. Each terminal 2 is inserted into each press-fitting hole 102, and the press-fitting locking portion 23 is press-fitted and locked in each press-fitting hole 102, whereby the terminal 2 is held by the connector housing 101. In each terminal 2, the contact portion 21 is exposed in the contact-side space portion 105 in a state where the press-fit locking portion 23 is press-fitted and locked in each press-fitting hole 102, and the connection portion 22 is connected to the connection-side space portion 106. Projects outward. In addition, each terminal 2 protruded from the connection side space part 106, when the connector 100 is a PCB connector applied to a wire-to-board connection mechanism, for example, a printed circuit board (PCB). The connecting portion 22 side is bent in a predetermined direction and connected to the substrate.

  The chain terminal 1 shown in FIGS. 1, 2, 3, 4, 5, 6, 7, and 8 is applied when manufacturing the connector 100 as described above. Specifically, the chain terminal 1 includes the plurality of terminals 2 and the terminal holder 3 described above.

  The terminal holder 3 is formed in a strip shape and holds the plurality of terminals 2 so as to be detachable in parallel along a chain direction as an intersecting direction intersecting the terminal extending direction. The terminal holder 3 is sometimes called a carrier that holds the terminal 2. The terminal holder 3 is entirely formed in a strip shape from a conductive metal material or an insulating synthetic resin material. Here, the terminal extending direction is a direction in which the terminals 2 formed in a rod shape extend, and the chaining direction is an arrangement direction of the plurality of terminals 2. Typically, the terminal extension direction and the chain direction are orthogonal to each other. In the chain terminal 1, the center axis of each terminal 2 is along the width direction of the terminal holder 3 with respect to the band-shaped terminal holder 3, and the plurality of terminals 2 are spaced apart from each other by a predetermined distance in the length direction of the terminal holder 3. Held in parallel.

  Specifically, the terminal holder 3 has a holding part 31, and each terminal 2 is held by the holding part 31. The holding part 31 holds the terminal 2 that has been plated. The holding part 31 of this embodiment holds the plurality of terminals 2 at a pitch equivalent to the press-fitting hole pitch P1 (see FIG. 12 and the like) of the plurality of press-fitting holes 102 of the connector housing 101 into which the plurality of terminals 2 are press-fitted. Although various types of structures can be applied to the holding unit 31, here, as shown in FIG. 1 and the like, each terminal 2 is held by a pair of holding claws 32 and 33 facing each other in the chain direction. It is configured to do. The holding claws 32 and 33 are formed so as to protrude in the terminal extending direction and the direction orthogonal to the chain direction. Two pairs of holding claws 32 and 33 are provided for each terminal 2, and are provided on both side edges of the terminal holder 3 along the chain direction.

  Here, as described above, the press-fitting holes 102 are formed at a predetermined pitch and a predetermined number according to specifications, usage conditions, and the like required for a device to which the connector 100 is applied. The press-fit hole pitch P1 corresponds to the distance between the centers of the adjacent press-fit holes 102 as shown in FIG. More specifically, as will be described later, the press-fitting hole pitch P1 is an arrangement direction of the press-fitting holes 102 adjacent to each other along the arrangement direction of the press-fitting holes 102 in a row in which the plurality of terminals 2 are collectively inserted into the press-fitting holes 102. It corresponds to the distance between the centers along. In the following description, the case where a plurality of terminals 2 are inserted into each press-fitting hole 102 in a lump with the left-right direction as a line toward FIG. 12 will be described. That is, in the example of FIG. 12, the horizontal direction is the column direction toward FIG. 12, and the vertical direction is the step direction toward FIG. In this case, the press-fitting hole pitch P1 corresponds to the center-to-center distance along the left-right direction of the press-fitting holes 102 adjacent in the left-right direction (column direction) toward FIG. Here, the press-fitting hole pitch P1 is substantially equal in each stage of each row.

  On the other hand, the terminal pitch P2, which is the pitch of the plurality of terminals 2 held by the terminal holder 3, corresponds to the distance between the centers of the adjacent terminals 2 as shown in FIGS. More specifically, the terminal pitch P2 is determined between the centers along the chain direction of adjacent terminals 2 along the chain direction orthogonal to the terminal extension direction in a state where each terminal 2 is held by the holding unit 31. Corresponds to distance. Each holding portion 31 holds each terminal 2 so that the terminal pitch P2 is equal to the press-fitting hole pitch P1. Here, the terminal pitch P <b> 2 is substantially the same between the adjacent terminals 2. Each holding portion 31 holds each terminal 2 so that each terminal 2 is substantially parallel to the direction orthogonal to the chaining direction, and accordingly, the chaining direction and the terminal extending direction are substantially orthogonal to each other. .

  In addition, the terminal holder 3 holds a group of terminals 2 in the same number as the number of rows of the plurality of press-fitting holes 102 formed in the connector housing 101. In other words, the plurality of holding portions 31 hold the number of terminals 2 equivalent to the number of one row of the plurality of press-fitting holes 102 as one group (hereinafter also referred to as “terminal group”). Furthermore, the plurality of holding portions 31 have a pitch equivalent to the press-fitting hole pitch P1 of the plurality of press-fitting holes 102 of the connector housing 101 into which the plurality of terminals 2 are press-fitted, and for one row of the plurality of press-fitting holes 102. The number of terminals 2 equal to the number (here, 11) is held as one terminal group. Here, the terminal holder 3 is illustrated as holding the terminals 2 on the contact portion 21 side with the press-fit locking portion 23 interposed therebetween, but is opposite to the contact portion 21 with the press-fit locking portion 23 interposed therebetween. Each terminal 2 may be held on the side connecting portion 22 side.

  The terminal holder 3 according to the present embodiment further includes a gripping portion 34, and improves the workability when the terminal holder 3 is detached from the plurality of terminals 2 by the gripping portion 34. The grip portion 34 is a portion that is gripped when the terminal holder 3 is removed from the terminal 2. The grip part 34 of this embodiment is formed in a rectangular plate shape. The holding part 34 extends on the side opposite to the terminal 2 side held by the holding part 31 with the holding part 31 as a reference.

  More specifically, the grip portion 34 extends along the extending direction of the terminal 2. The holding part 34 has a plurality of holding parts 31 arranged at one end in the extending direction along the crossing direction, and the terminal 2 in a state where the other end in the extending direction is held by the holding part 31. Furthermore, it protrudes on the opposite side to the holding part 31. The grip portion 34 has a length along the terminal extending direction, and the grip portion 34 protrudes outward from the hood portion 103 in a state where the terminal 2 held in the holding portion 31 is inserted into the press-fit hole 102. (See FIG. 4 and the like).

  The terminal holder 3 is integrally formed as a whole including the holding portion 31, the gripping portion 34 and the like. For example, after the holding claws 32 and 33 constituting the holding portion 31 are formed by pressing / cutting or the like, the terminal holder 3 is bent, and the other end portion in the terminal extending direction is bent. The folded portion 35 is formed. The folding | returning part 35 functions also as a site | part which adjusts the position of the terminal extension direction of the terminal 2 hold | maintained at each holding | maintenance part 31, and the direction orthogonal to a chain direction to an appropriate position. That is, in the terminal holder 3, the folded portion 35 formed at one end in the terminal extending direction is interposed between each terminal 2 held by each holding portion 31 and the main body portion of the holding portion 34. Each terminal 2 can be held at a position that is lifted from the main body portion of the gripping portion 34 by the amount of the folded portion 35. Thereby, the terminal holder 3 can suppress that the contact part 21 side of each terminal 2 contacts with the main-body part of the holding part 34, and is damaged.

  Next, a connector manufacturing method using the chain terminal 1 will be described with reference to FIGS. 3, 4, 5, 6, 7, and 8. The connector manufacturing method described below will be described as being performed manually by an operator.

  First, as shown in FIG. 3, as a temporary insertion process, the worker collectively puts the plurality of terminals 2 held by the terminal holder 3 into the plurality of press-fitting holes 102 of the connector housing 101 along the terminal press-fitting direction. Insert temporarily. In this case, the worker temporarily inserts the connection portions 22 side of the plurality of terminals 2 held by the terminal holder 3 into the press-fitting holes 102 for one row at a time from the contact-side space portion 105 side of the connector housing 101. . 4 and 5 illustrate a state in which the connection portions 22 of the plurality of terminals 2 held by the terminal holder 3 are temporarily inserted into the press-fitting holes 102 for one row at a time.

  Next, as a removal process, the worker temporarily removes the terminal holder 3 from the state in which the plurality of terminals 2 held by the terminal holder 3 are temporarily inserted into the press-fitting holes 102, as shown in FIG. The terminal holder 3 is removed from the plurality of terminals 2 while being pulled out along the terminal counter-pressing direction in the opposite direction. In this case, the worker grasps the grip portion 34 of the terminal holder 3 from the contact-side space portion 105 side and removes each terminal 2 while pulling out the terminal holder 3 along with the grip portion 34 along the terminal counter-pressing direction. Thus, the terminal holder 3 can be easily detached from the terminal 2. 7 and 8 show a state in which the terminal holder 3 is removed from the plurality of terminals 2.

  Thereafter, as a press-fitting process, the worker uses various press-fitting jigs to press the terminal 2 temporarily inserted into the press-fitting hole 102 along the terminal press-fitting direction from the contact portion 21 side. The press-fit locking portion 23 is press-fitted into each press-fit hole 102 and is pressed until it is locked in each press-fit hole 102. The operator removes the press-fitting jig when the press-fitting locking portion 23 of each terminal 2 is press-fitted into each press-fitting hole 102. The worker repeats the above process for all the stages of the plurality of press-fitting holes 102 and finally completes the connector 100. FIG. 11 shows an example of a connector 100 manufactured by the connector manufacturing method.

  Note that the press-fitting process may be performed in a batch for all stages after the temporary insertion of the terminals 2 of all stages is completed. Further, when the connector 100 is a PCB connector, the worker completes the PCB connector by bending the connection portion 22 side of each terminal 2 protruding from the connection-side space portion 106 in a predetermined direction.

  According to the chain terminal 1 described above, a plurality of terminals 2 formed in a rod shape and a plurality of terminals 2 formed in a strip shape can be attached and detached in parallel along the crossing direction intersecting the extending direction of the terminals 2. And a plurality of terminal holders 3 for holding the plurality of terminals 2 at a pitch equivalent to the press-fit hole pitch P1 of the plurality of press-fit holes 102 of the connector housing 101 into which the plurality of terminals 2 are press-fitted. Holding part 31 and a holding part 34 to be held when the terminal holder 3 is detached from the terminal 2.

  Accordingly, since the terminal holder 3 that holds the plurality of terminals 2 by the plurality of holding portions 31 has the gripping portion 34, the chain terminal 1 holds the gripping portion 34 when removing the terminal holder 3 from the terminal 2. The terminal holder 3 can be removed. That is, an operator or the like can easily remove the terminal holder 3 from the terminal 2 by holding the holding portion 34 of the terminal holder 3 and removing each terminal 2 while pulling out the terminal holder 3 together with the holding portion 34. . As a result, this chain terminal 1 can improve workability when the terminal holder 3 is detached from the plurality of terminals 2.

  Furthermore, according to the chain terminal 1 demonstrated above, the holding part 34 is extended on the opposite side to the terminal 2 side of the state hold | maintained at the said holding part 31 on the basis of the holding part 31. FIG. Therefore, the chain terminal 1 can reliably handle the terminal holder 3 by gripping the gripping portion 34 when the terminal 2 is press-fitted into the press-fitting hole 102 or when the terminal holder 3 is removed from each terminal 2. The property can be further improved.

  Furthermore, according to the chain terminal 1 demonstrated above, the holding part 34 is extended along the extension direction of the terminal 2, and the some holding | maintenance part 31 is crossed in one edge part of the said extension direction. The other end portion in the extending direction protrudes from the terminal 2 in a state of being held by the holding portion 31 to the side opposite to the holding portion 31. Therefore, the chain terminal 1 can suppress interference between the end portion of each terminal 2 held by the holding portion 31 and the grip portion 34, and reliably when the terminal holder 3 is removed from each terminal 2. Since the terminal holder 3 can be pulled out by gripping the grip portion 34, workability when removing the terminal holder 3 from the plurality of terminals 2 can be further improved.

  Further, according to the chain terminal 1 described above, the press-fitting hole 102 is formed inside the hood portion 103 of the connector housing 101, and the holding portion 34 has a length along the extending direction of the terminal 2. In a state where the terminal 2 held by the portion 31 is inserted into the press-fitting hole 102, the grip portion 34 is formed to have a length protruding outward from the hood portion 103. Therefore, the chain terminal 1 is exposed to the outside of the hood portion 103 of the connector housing 101 in a state where the terminal 2 held by the holding portion 31 is inserted into the press-fitting hole 102. Even when the terminal 2 is assembled to the connector housing 101 having the above, workability when the terminal holder 3 is detached from the plurality of terminals 2 can be improved.

  Here, as described above, in the connector housing 101, the distance from the opening in the contact side space 105 to the partition wall 104 is relatively long, and the distance from the opening in the connection side space 106 to the partition wall 104 is longer. Is formed to be relatively short. At this time, as described above, when the terminal holder 3 is removed from the terminal 2, the terminal holder 3 is removed from the contact side space 105 side, that is, from the opening on the side where the distance to the partition wall 104 is relatively long. Even if it is the structure which removes, if it is the chain terminal 1 of this embodiment, the holding part 34 which protruded along the extension direction can be hold | gripped, and the terminal holder 3 can be pulled out easily. Also in this respect, the chain terminal 1 can improve workability when the terminal holder 3 is detached from the plurality of terminals 2.

  In addition, the chain terminal which concerns on embodiment of this invention mentioned above is not limited to embodiment mentioned above, A various change is possible in the range described in the claim.

  In the chain terminal 1 </ b> A according to the modification shown in FIG. 9, the terminal 2 includes a pressing force transmission protrusion 224. The pressing force transmission protrusion 224 is configured by, for example, a protrusion formed on the outer surface of each terminal 2. The pressing force transmission protrusion 224 protrudes from the outer surface of each terminal 2 along a direction orthogonal to the terminal extending direction. The pressing force transmission protrusion 224 is formed between the end on the contact portion 21 side and the press-fit locking portion 23 in each terminal 2. The pressing force transmission protrusion 224 is formed at a position where the terminal 2 comes into contact with the holding claws 32 and 33 in a state where the terminals 2 are held between the holding claws 32 and 33 of the holding parts 31. The pressing force transmitting projection 224 is a surface (in other words, the press-fitting hole 102) of the holding claws 32, 33 in the state where the terminals 2 are sandwiched between the holding claws 32, 33 of the holding parts 31. The surface on the side where is located.

  The chain terminal 1 </ b> A configured as described above is configured so that, for example, when the terminals 2 are press-fitted into the press-fitting holes 102, for example, without using a press-fitting jig, the terminal holder 3 passes through the pressing force transmission protrusion 224. The pressing force required for press-fitting can be transmitted directly to the terminal 2. As a result, the chain terminal 1A can reduce the number of work steps when the terminals 2 are press-fitted into the press-fitting holes 102, and the workability can be further improved.

  Further, in the chain terminal 1B according to the modified example shown in FIG. 10, the holding portion 334 included in the terminal holder 3 is formed in a T-shaped plate shape. More specifically, the grip portion 334 extends along the extending direction of the terminal 2. The grip portion 334 has a plurality of holding portions 31 arranged at one end portion in the extending direction along the crossing direction, and the terminal 2 in a state where the other end portion in the extending direction is held by the holding portion 31. Furthermore, it protrudes on the opposite side to the holding part 31. And this holding | grip part 334 protrudes as a rod-shaped rod-shaped part 334a in the other end part of a terminal extending direction with respect to one end part of the terminal extending direction where the holding | maintenance part 31 was arranged, T A letter-shaped plate shape is formed.

  The chain terminal 1B configured as described above can grip the rod-shaped portion 334a of the grip portion 334 when the grip portion 334 is gripped so as to remove the terminal holder 3 from the terminal 2, and an operator can grip the grip portion 334a. Since it can be set as the structure which is easy to hold | grip 334, the workability | operativity at the time of removing the terminal holder 3 from the some terminal 2 can further be improved.

  In the above description, the terminal extending direction and the chaining direction (crossing direction) have been described as being orthogonal to each other.

  Although the holding part demonstrated above demonstrated as what hold | maintains and hold | maintains each terminal 2 with a pair of holding nail | claw 32,33 which opposes the chain | linkage direction, it is not restricted to this, The structure of another form may be sufficient. .

  What is necessary is just to set arbitrarily about the row direction which inserts the several terminal 2 demonstrated above in each press-fit hole 102 collectively. For example, in the plurality of press-fitting holes 102, the plurality of terminals 2 may be inserted in a lump with the vertical direction as a line toward FIG. In this case, the vertical direction is the column direction toward FIG. 12, the horizontal direction is the step direction toward FIG. 12, and the press-fitting hole pitch P1 is the press-fitting hole 102 adjacent to the vertical direction (column direction) toward FIG. This corresponds to the center-to-center distance along the vertical direction. In this case, in the plurality of press-fitting holes 102, since the plurality of terminals 2 are collectively inserted into the press-fitting holes 102 with the vertical direction as one row toward FIG. 12, the terminal holder 3 is provided for one row of the plurality of press-fitting holes 102. The number of terminals 2 equal to the number of terminals, that is, four terminals 2 are held as one terminal group.

  In the above description, the press-fit hole pitch P1 is substantially the same in each row, and the terminal pitch P2 is described as being substantially the same between the adjacent terminals 2. Not exclusively. For example, the press-fitting hole pitch P1 may be different from each other in each of the plurality of press-fitting holes 102. In this case, for example, the chain terminal 1 may have a terminal pitch P2 corresponding to the press-fitting hole pitch P1 for each stage. Further, the press-fitting hole pitch P <b> 1 may be different from each other in each row in the plurality of press-fitting holes 102.
