Description

  The present invention relates to a terminal holder and a method of manufacturing the terminal holder, and more particularly to a terminal holder in which a plurality of terminals having an intermediate carrier structure are assembled and a method of manufacturing a terminal holder in which a plurality of terminals having an intermediate carrier structure are assembled.

Conventionally, a terminal holder has a plurality of terminals assembled on the front and back surfaces of the main body. In order to simplify the assembling operation, the plurality of terminals are connected in advance with a connecting piece (same as “carrier”) to form a comb-like shape, and the invention is disclosed in which the connecting piece is cut after assembling. (For example, see Patent Documents 1 and 2).
Moreover, although several terminals are assembled | attached only to the surface of a main body, the invention which connects a part of intermediate range of a terminal beforehand with a connection piece, and cut | disconnects a connection piece after an assembly is disclosed. For example, see Patent Document 3).

Japanese Patent Laying-Open No. 2015-26581 (page 4-5, FIG. 1) JP 2000-251999 A (page 3-4, FIG. 1) JP 2003-36951 A (page 3-4, FIG. 1)

Since the inventions disclosed in Patent Documents 1 and 2 both cut the connecting piece that connected the tip (same as “tip carrier structure”), the tip is damaged by cutting, and the tip The plating peels off and the wettability of the solder decreases, or the tip is bent, making it difficult to connect to other terminals. For this reason, there has been a problem that the manufacturing cost is increased due to a correction operation for performing additional plating or additional processing on the tip portion or a decrease in yield due to disposal.
On the other hand, since the invention disclosed in Patent Document 3 cuts the connecting piece that has connected a part of the intermediate range (same as “intermediate carrier structure”), there is no problem such as the additional plating. Since a plurality of terminals cannot be assembled to the front surface and the back surface of the main body, respectively, there is a problem in that downsizing is hindered because a large size is required when many terminals are assembled on one surface.

  The present invention solves the above-described problems, and provides a terminal holder and a method for manufacturing the terminal holder that enable miniaturization while preventing damage to the tip of the terminal.

A terminal holder according to the present invention includes a plate-shaped main body having a first surface and a second surface facing each other, a plurality of first terminals assembled to the first surface in an intermediate range in a longitudinal direction, A plurality of second terminals assembled on two surfaces in an intermediate range in the longitudinal direction;
The first terminals are spaced apart from each other in the width direction, and adjacent side edges of the intermediate range in the longitudinal direction are each formed with a first connecting piece remaining portion facing each other in the width direction with a first gap in the width direction. And
The second terminals are arranged in the same phase in the width direction as the first terminals, and are opposed to each other in an oblique direction with a substantially longitudinal second gap between adjacent side edges in the intermediate range in the longitudinal direction. The second connecting piece remaining portion is formed.
Further, the first connecting piece remaining portion and the second connecting piece remaining portion are arranged in different phases in the longitudinal direction.
Furthermore, the manufacturing method of the terminal holder according to the present invention includes a first connecting piece connected to the first face of the main body having the first face and the second face facing each other by a first connecting piece in the middle range in the longitudinal direction. Assembling one terminal;
Holding the assembled first terminal and cutting a central portion of the first connecting piece;
Assembling a second terminal connected to each other by a second connecting piece in an intermediate range in the longitudinal direction on the second surface;
Holding a part of the assembled second connecting piece and cutting out a part of the second connecting piece;
The second connecting piece is formed in a crank shape including a second connecting piece remaining portion in the width direction and a second connecting piece cutting portion in the longitudinal direction sandwiched between the second connecting piece remaining portions,
When the second connecting piece excision portion is cut out in a state where the second connecting piece remaining portion is held, between the second connecting piece remaining portions facing each other in the oblique direction, the second in the substantially longitudinal direction. A gap is formed.
Furthermore, a first working hole for holding a part of the first terminal and a part of the second connecting piece, each of which penetrates the main body and opens to the first surface and the second surface. A second working hole is formed, and the first working hole and the second working hole are arranged at different positions in the longitudinal direction.

In the terminal holder according to the present invention, since the first terminal and the second terminal are arranged in the same phase in the width direction, downsizing is promoted.
Further, since the first terminal and the second terminal have an “intermediate carrier structure” in which intermediate ranges in the longitudinal direction are connected, it is not necessary to perform additional processing or plating after assembly, thereby reducing the manufacturing cost.
Furthermore, since the second connecting piece is formed in a crank shape and the second gap in the substantially longitudinal direction is formed while the second connecting piece remaining portion is held, it is easy to ensure the clearance between the second connecting piece remaining portions. Thus, there is no risk of leakage between the electrodes, and the reliability is improved.

[Embodiment 1]
(Terminal holder)
1 and 2 schematically illustrate a terminal holder according to Embodiment 1, FIG. 1 is a perspective view, and FIG. 2 is a plan view. In FIG. 2, a portion corresponding to the main body (see FIG. 3) is hatched to make the first working hole, the second working hole, the first terminal, and the second terminal easy to understand (the hatched portion is therefore It does not show a cross section).

1 and 2, the terminal holder 200 includes a plate-like main body 100 having a first surface 110 and a second surface 120 facing each other, and a first intermediate body having a longitudinal intermediate range assembled to the first surface 110. It has the terminal 10 and the 2nd terminal 20 with which the intermediate range of the longitudinal direction was assembled | attached to the 2nd surface 120. FIG.
The first terminal 10 and the second terminal 20 are arranged in the same phase in a direction perpendicular to the longitudinal direction (hereinafter referred to as “width direction”). Therefore, in FIG. 2 which is a plan view, an intermediate range of the second terminal 20 is visually recognized, and only the first connecting piece remaining portion 12 is visually recognized for the first terminal 10. On the other hand, in the rear view (not shown), the intermediate range of the first terminal 10 is visually recognized, and only the second connecting piece remaining part 22 is visually recognized for the second terminal 20.
Note that the number of the first terminals 10 and the number of the second terminals 20 is five, but the present invention is not limited to this, and may be any number as long as there are a plurality. Further, the first terminal 10 and the second terminal 20 have the same width in a plan view and a crank shape in a side view. However, the present invention is not limited to this, and the first terminal 10 and the second terminal 20 have different widths, L shapes, or straight shapes. There may be.

(Body)
The main body 100 is formed with a first protrusion 150 that protrudes toward the second surface 120 at one end (right side in FIG. 1) of the main body 100, and the other side (left side in FIG. 1) of the main body 100. A second protrusion 160 that protrudes toward the first surface 110 is formed at the end of the first protrusion 110. Furthermore, a first working hole 130 opened in the first surface 110 and the second surface 120 is formed at a position near the first protrusion 150, and a second working hole opened in the first surface 110 and the second surface 120, respectively. 140 is formed at a position near the second protrusion 160.
As a guide means for assembling the second terminal 20, the second protrusion 160 has the second rising hole 122, the second surface 120 has the second guide groove 123, and the first protrusion 150 has the second rising. A groove 125 is formed. A pair of second claws 124 are provided on both sides of the second guide groove 123 as fixing means for fixing the second terminal 20.
Similarly, a first rising hole 121 is formed in the first protrusion 150 as guide means for assembling the first terminal 10. Further, a first guide groove is formed on the first surface 110, and a first rising groove is formed on the second protrusion 160, and a pair of both sides of the first guide groove is used as a fixing means for fixing the first terminal 10. The 1st nail | claw is provided (all are not shown in figure).
At this time, the second guide groove 123 and the first guide groove (not shown) are formed in the same phase in the width direction.
When the first terminal 10 and the second terminal 20 are not crank-shaped in a side view,
Depending on each shape, the form of the first protrusion 150 and the second protrusion 160 is changed (including removal).

(Second terminal)
The second terminals 20 are arranged in parallel to each other in the width direction, each part of the second terminal 20 passes through the second rising hole 122, the middle range in the longitudinal direction is guided by the second guide groove 123 and fixed by the second claw 124. In addition, a part has entered the second rising groove 125.
Then, in the range close to the second protrusion 160 in the longitudinal intermediate range (the range on the other side), that is, in the position of the second working hole 140, the adjacent side edges in the longitudinal intermediate range are respectively connected to each other. A second connecting piece remaining portion 22 is formed opposite to each other with a gap 24 therebetween.
At this time, the position of the second connecting piece remaining portion 22 formed on one side edge of the second terminal 20 and the position of the second connecting piece remaining portion 22 formed on the other side edge are shifted in the longitudinal direction. For this reason (because they are not in the same phase), the second gap 24 is sandwiched between the pair of second connecting piece remaining portions 22 in a substantially longitudinal direction.
Further, the second terminal 20 has an “intermediate carrier structure”, that is, the second connection piece remaining portions 22 that are initially connected by the crank-shaped second connection piece 21 are incorporated into the main body 100, and then the second terminal 20. The central portion of the connecting piece 21 is cut out (this will be described in detail in the second embodiment).

(First terminal)
The first terminals 10 are arranged in parallel with each other in the width direction in a form similar to the second terminals 20, and a part thereof penetrates the first rising holes 121. Further, an intermediate range in the longitudinal direction is guided by the first guide groove and fixed by the first pawl, and a part of the intermediate range enters the first rising groove (none of which is shown).
Then, in the range (one side range) close to the first protrusion 150 in the intermediate range in the longitudinal direction, that is, in the position of the first working hole 130, the adjacent side edges in the intermediate range in the longitudinal direction are respectively A first connecting piece remaining portion 12 is formed opposite to each other with a gap 14 therebetween.
At this time, in FIG. 2, the position of the first connecting piece remaining portion 12 formed on one side edge of the first terminal 10 and the first side edge formed on the other side edge are visible through the first working hole 130. Since the position of the one connecting piece remaining portion 12 is in the same phase in the longitudinal direction, the first gap 14 is sandwiched in the width direction by the pair of first connecting piece remaining portions 12.
In addition, the first terminal 10 has an “intermediate carrier structure”, that is, the first connection piece remaining portions 12 that are initially connected by the linear first connection pieces 11 are incorporated into the main body 100, The central part of the connecting piece 11 is cut out (this will be described in detail in the second embodiment).
The first terminal 10 has the same carrier structure as that of the second terminal 20, and the first gap 14 in the substantially longitudinal direction is formed by the pair of first connection piece remaining portions 12 in the crank-shaped first connection piece 11. It may be.

(Function and effect)
As described above, since the first guide groove (not shown) and the second guide groove 123 are arranged in the same phase in the width direction, the terminal holder 200 is promoted to be downsized.
Further, since the first terminal 10 and the second terminal 20 have an “intermediate carrier structure”, the initial properties of the terminal tip are maintained, so that it is possible to perform desired processing and plating treatment in advance and to assemble the first terminal 10 and the second terminal 20. Later, no additional processing or plating is required. Therefore, the manufacturing cost is reduced.
Furthermore, since the second gap 24 has a shape in which the substantially longitudinal direction is sandwiched between the second connecting piece remaining portions 22, it becomes easy to secure the clearance between the second connecting piece remaining portions 22, and there is a risk of leakage between the electrodes. Disappears. Therefore, reliability is improved.
When the miniaturization is promoted, the first terminals 10 also approach each other, and the first gap in the width direction tends to be narrowed. For this reason, the first connecting piece 11 of the first terminal 10 is also formed in a crank shape like the second connecting piece 21 of the second terminal 20, and the first gap 14 is formed in a substantially longitudinal direction to ensure a clearance. It is possible to eliminate the risk of leakage between electrodes and further promote downsizing.

4 to 6, the portion corresponding to the main body shown in FIG. 3 is shaded to make the first working hole, the second working hole, the first terminal, and the second terminal easy to understand (therefore, accordingly). (The shaded area does not indicate a cross section).
Since the manufacturing method of the terminal holder according to the second embodiment is a method of manufacturing the terminal holder 200 described in the first embodiment, the names and symbols of the respective parts are the same as those in the first embodiment, and a part of the description will be given. Is omitted.

(Before assembly: S0)
In FIG. 3, a second rising hole 122, a second guide groove 123, a second claw 124, and a second rising groove 125 are formed on the second surface 120 of the main body 100 (see Embodiment 1). A pair of second claws 124 are provided on both sides of the second guide groove 123 as a fixing means for fixing the second terminal 20. Furthermore, the opened 1st work hole 130 and the 2nd work hole 140 are formed.
On the other hand, the back side (the first surface 110 side) (not shown) has the same form as the plane side (the second surface 120 side), and a first guide groove (not shown) is formed on the first surface 110 in the second protrusion 160. A first guide groove and a first claw (both not shown) are formed. In addition, a first rising hole 121 is formed in the first protrusion 150.

(Step of assembling the first terminal: S1)
4 and 7, the five first terminals 10 are assembled. At this time, the five first terminals 10 are arranged in parallel to each other, and have an “intermediate carrier structure” in which side edges of adjacent intermediate ranges in the longitudinal direction are connected by the first connecting pieces 11 (intermediate in the longitudinal direction). The range refers to a range excluding both ends, and is not necessarily limited to a range including the center of both ends).
That is, one of the first terminals 10 passes through the first rising hole 121, the intermediate range in the longitudinal direction is guided to the first guide groove (not shown), and fixed by the first claw (not shown), A part is made to enter a first rising groove (not shown). Note that the order of such operations is not limited and may be performed in parallel. Therefore, the range of the first terminal 10 including the first connection piece 11 is visually recognized through the first work hole 130, and the range not including the first connection piece 11 is visually recognized through the second work hole 140.
At this time, the first connection piece 11 is a straight plate piece in plan view, and the first connection piece excision part 13 excised in a process described later and a pair of first connections remaining without being excised in the process described later. This is a combination of the remaining part 12.

(Step of cutting off the connecting piece of the first terminal: S2)
In FIG. 5, the first connecting piece excision 13 of the first connecting piece 11 is cut to form the first gap 14. That is, in the first working hole 130, a first holding position 15 (indicated by a black circle in FIG. 5) of the first terminal 10 is held by a jig (not shown), and the first connecting piece excision 13 is held by a cutting tool (not shown). Excising.
Therefore, the first connecting piece remaining portion 12 protruding in the width direction remains on both side edges of the first terminal, and the first gap 14 in the width direction is formed. In other words, the first gap 14 is located at the same position in the longitudinal direction and is sandwiched in the width direction by the pair of first connecting piece remaining portions 12 facing in the width direction.

(Step of assembling the second terminal: S3)
6 and 7, the five second terminals 20 are assembled. At this time, the five second terminals 20 are arranged in parallel to each other, and have an “intermediate carrier structure” in which the side edges of adjacent intermediate ranges in the longitudinal direction are connected by the second connecting pieces 21 (intermediate in the longitudinal direction). The range refers to a range excluding both ends, and is not necessarily limited to a range including the center of both ends).
That is, the other end of the second terminal 20 passes through the second rising hole 122, the middle range in the longitudinal direction is guided to the second guide groove 123 and fixed by the second pawl 124, and one part of the second terminal 20 is second raised. Enter the raised groove 125. Note that the order of such operations is not limited and may be performed in parallel.
At this time, the second terminal 20 has the same phase as that of the first terminal 10 in the width direction. Therefore, in a plan view (viewed from the second surface 120 toward the first surface 110), only the first connecting piece remaining portion 12 and the tip of one of the first terminals are visible, and the range excluding this is the second terminal. It cannot be visually recognized in the state covered with 20. On the other hand, in the rear view (viewed from the first surface 110 toward the second surface 120), only the second connecting piece 21 and the tip of one of the second terminals are visible, and the range excluding this is the first terminal 10. It cannot be visually recognized in a state covered with (not shown).
The second connecting piece 21 is a crank-shaped plate piece in plan view, and is a second connecting piece cutting portion 23 in the longitudinal direction that is cut off in a later-described step, and a pair of widths that remain uncut in the later-described step. The second connecting piece remaining portion 22 in the direction is combined.

(Step of cutting off the connecting piece of the second terminal: S4)
In FIG. 8 and again in FIG. 2, the second connecting piece excision 23 of the second connecting piece 21 is cut to form the second gap 24. That is, in the second working hole 140, the second connecting piece remaining portion 22 (shown by a black circle in FIGS. 6 and 8) of the second connecting piece 21 is held by a jig (not shown), and the second connecting piece is cut by a cutting tool (not shown). The excision part 23 is excised.
Therefore, the second connecting piece remaining portions 22 projecting in the width direction remain on both side edges of the second terminal, and the oblique second gap 24 is formed. That is, the second gap 24 is not located at the same position in the longitudinal direction, but is substantially sandwiched in the longitudinal direction by the pair of second connecting piece remaining portions 22 that face in an oblique direction.

(Function and effect)
As described above, the method of manufacturing the terminal holder 200 has the following effects because the second connecting piece 21 that connects the second terminals 20 has a crank shape in plan view.
That is, since the first terminal 10 and the second terminal 20 having the intermediate carrier structure are arranged in the same phase in the width direction, the second terminal 20 is assembled after the first terminal 10 is assembled. The terminal 10 and the second terminal 20 overlap each other, and the range excluding the second connecting piece 21 of the second terminal 20 cannot be gripped with a jig.
However, since the second connecting piece 21 is arranged in a phase different from that of the first terminal 10 and the first connecting piece remaining portion 12, the second connecting piece remaining portion 22 which is a part of the second connecting piece 21 is cured. It can be gripped with a tool. Moreover, since the second connecting piece remaining portions 22 are sufficiently separated from each other in the longitudinal direction, the second connecting piece remaining portion 22 can be securely held, and after the second connecting piece cutting portion 23 is cut off. The width (distance) of the formed second gap 24 can be ensured.
Therefore, it is possible to promote the miniaturization of the terminal holder 200 without increasing the interval between the second terminals 20, and it becomes easy to secure the clearance between the second connecting piece remaining portions 22, and the leakage between the electrodes can be reduced. There is no fear and reliability is improved.
In addition, since the first terminal 10 and the second terminal 20 can maintain the terminal tip at the initial property, it is possible to perform a desired processing or plating process in advance, and after the assembly, additional processing or It is not necessary to perform the plating process, and the manufacturing cost can be reduced.
If the miniaturization is promoted, the first terminals 10 come closer to each other, and the first gap in the width direction becomes narrow. Therefore, the first connection piece 11 of the first terminal 10 is also the second connection piece 21 of the second terminal 20. Similarly to the above, the first gripping position 15 may be the first connecting piece cutting portion 13 in a crank shape. If it does so, since the 1st connection piece cutting part 13 can be cut out in the state which hold | maintained the 1st connection piece cutting part 13 reliably with the jig | tool, it will become possible to form the 1st clearance gap 14 in a substantially longitudinal direction. . That is, the clearance of the first gap 14 is ensured to eliminate the risk of leakage between electrodes, and the downsizing is promoted, and the risk of leakage between electrodes is eliminated, thereby improving the reliability.

  The present invention has been described based on the first and second embodiments. It is understood by those skilled in the art that the first and second embodiments are merely examples, and various modifications are possible for each of the components and combinations thereof, and that such modifications are also within the scope of the present invention. is there.
