JP 2005-135669 A

  As in the connector of Patent Document 1, when a single connector has a power supply terminal electrically connected to a power supply and a signal transmission terminal for transmitting an electric signal, The cross section of the power supply terminal is larger than that of the signal transmission terminal (see paragraph 0044). This is because (a) the amount of heat generated at the terminal needs to be reduced, and (b) the current flowing through the power supply terminal is larger than the current flowing through the signal terminal. In addition, since the shape of the male terminal for power supply and the male terminal for signal transmission are greatly different in this way, when manufacturing each male terminal, it is necessary to manufacture by a manufacturing process dedicated to each male terminal. There is.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a connector capable of manufacturing both a power supply male terminal and a signal transmission male terminal by a similar manufacturing process, and a manufacturing method thereof.

  (1) In order to solve the above-described problems, a connector according to the present invention is a connector that is electrically connected to a mating connector having a female terminal for power supply and a female terminal for signal transmission. Manufactured using the power supply female terminal and the power supply male terminal electrically connected to the power supply, and manufactured using a wire, and electrically connected to the signal transmission female terminal. And a signal transmission male terminal used for transmission of an electrical signal, and a connector housing having a wall portion supporting the male terminal for power supply and the male terminal for signal transmission. Each of the power supply male terminal and the signal transmission male terminal is inserted into a through hole formed in the wall, and each of the power supply male terminal and the signal transmission male terminal is inserted into the through hole. An insertion portion to be inserted and a terminal connection portion that protrudes from the wall portion and is connected to the female terminal for power supply or the female terminal for signal transmission are formed. The conductivity is higher than the material of the male terminal for signal transmission.

  In this configuration, since the conductivity of the material for the power supply male terminal is higher than that of the material for the signal transmission male terminal, it is necessary to change the terminal shape between the power supply male terminal and the signal transmission male terminal. There is no. And since the difference between the male terminal for power supply and the male terminal for signal transmission is only the material, for example, by replacing the reel around which the wire is wound, the manufacture of the male terminal for power supply and the signal transmission The production of the male terminal can be easily switched. Therefore, both the male terminal for power supply and the male terminal for signal transmission can be manufactured by the same manufacturing process.

  Moreover, according to this structure, the metal terminal press metal mold | die becomes unnecessary by manufacturing a male terminal using a wire. Therefore, the male terminal can be manufactured in a short period of time, and the manufacturing cost of the male terminal is reduced.

  In addition, when a male terminal is manufactured by press working on a metal plate, the portion excluding the male terminal becomes scrap, but in this configuration, the male terminal is manufactured using a wire material, so that scrap is generated. Can be suppressed. Therefore, useless material costs can be reduced.

  The electric signals in the “signal transmission female terminal” and the “signal transmission male terminal” may flow from the connector side to the mating connector side, or may flow in the opposite direction. The signal transmission female terminal and the signal transmission male terminal are directly connected to a signal transmission wire, a signal transmission terminal fitting, or the like.

  The power supply female terminal and the signal transmission female terminal of the mating connector may have the same structure or different structures.

  Regarding the material of the male terminal for signal transmission and the male terminal for power supply, for example, as a male terminal for signal transmission, seven three brasses (copper 70%, zinc 30%, conductivity 28% IACS), and a power male terminal As the material, a copper alloy (conductivity 60% IACS) of 97.5% copper, 2.3% iron, 0.1% zinc and 0.1% phosphorus can be used. Even when other materials are used, they may be combined so that the electrical conductivity of the power male terminal material is larger than the electrical conductivity of the signal transmitting male terminal material.

  Further, the ratio of the conductivity [unit:% IACS] of the material for the power supply male terminal to the conductivity [unit:% IACS] of the material for the signal transmission male terminal is preferably 2 or more. Further, the higher the purity of the copper of the terminal, the higher the electrical conductivity and the lower the mechanical strength. Therefore, the terminal material is preferably a copper alloy with improved mechanical strength.

(2) In the connector according to the present invention, the through-hole, to the connection direction of the female terminal and the male terminal said power supply source, that is formed along the inclined direction.

  In this configuration, the through hole into which the male terminal is inserted is formed along a direction inclined with respect to the connecting direction of the female terminal and the male terminal. Therefore, when the connector and the mating connector are connected, the male terminal is pushed by the female terminal due to friction (friction between the female terminal and the male terminal) or displacement (position displacement of the female terminal with respect to the male terminal position). Even in this case, the male terminal is pressed against the inner surface of the through hole. As a result, since the sliding movement of the male terminal along the through hole is suppressed, the male terminal is not easily pushed out from the through hole of the wall portion.

  In this configuration, the insertion portion is formed along a direction inclined with respect to the connection direction, and the terminal connection portion is formed along the connection direction. Therefore, the male terminal is bent at a position between the insertion portion of the male terminal and the terminal connection portion. Further, the “connection direction of the power supply female terminal and the power supply male terminal” may be equal to the direction (housing connection direction) in which the mating connector housing and the connector housing are connected, or the terminal connection direction and the housing It does not have to coincide with the connection direction. For example, after both connector housings are connected, the terminals may be connected along a direction different from the housing connection direction. The “connection direction of the power supply female terminal and the power supply male terminal” is equal to the connection direction of the signal transmission female terminal and the signal transmission male terminal.

  The connector housing is a member having a wall portion that supports the male terminal, and the connector housing may include a main body portion and a cover housing attached to the main body portion in addition to the wall portion.

  The connector housing may be integrally formed including the wall portion, or the main body portion and the wall portion of the connector housing may be separate articles. In this case, the material of the main body portion and the wall portion may be different or the same. Moreover, the connector may have a board | substrate inside, In this case, the wall part may be attached to the board | substrate, and the wall part may be attached to the main-body part of the connector.

  (3) Further, in order to solve the above-described problem, the method for manufacturing a connector according to the present invention is electrically connected to a mating connector having a female terminal for power supply and a female terminal for signal transmission. ) The female terminal for power supply and the male terminal for power supply electrically connected to the power supply; and (ii) the electrical connection to the female terminal for signal transmission and transmission of the electrical signal. A method of manufacturing a connector having a male terminal for signal transmission used in the above-mentioned method, wherein the wire material that is the material of the male terminal for power supply and the wire material that is the material of the male terminal for signal transmission are cut off from the wire material assembly. And a connector housing forming step of forming a connector housing having a wall portion for supporting the male terminal for power supply and the male terminal for signal transmission, and inserting each of the wires into a through hole formed in the wall portion Insertion process to Bending to form an insertion part inserted into the through hole and a terminal connection part protruding from the wall part and connected to the power supply female terminal or the signal transmission female terminal by bending the wire. A process. In the cutting step, a material having higher conductivity than the material of the signal transmission male terminal is used as the material of the power source male terminal.

  In this method, since the electrical conductivity of the material for the male terminal for power supply is higher than that of the material for the male terminal for signal transmission, the terminal shape of the male terminal for power supply and the male terminal for signal transmission is There is no need to change. And since the difference between the male terminal for power supply and the male terminal for signal transmission is only the material, for example, by replacing the reel around which the wire is wound, the manufacture of the male terminal for power supply and the signal transmission The production of the male terminal can be easily switched. Therefore, both the male terminal for power supply and the male terminal for signal transmission can be manufactured by the same manufacturing process.

  Moreover, in this method, a metal terminal is not required for manufacturing a male terminal using a wire. Therefore, the male terminal can be manufactured in a short period of time, and the manufacturing cost of the male terminal is reduced.

  In addition, when a male terminal is manufactured by pressing a metal plate, the portion excluding the male terminal becomes scrap. However, in this method, since the male terminal is manufactured using a wire, scrap is generated. Can be suppressed. Therefore, useless material costs can be reduced.

The cutting process, the connector housing forming process, the inserting process, and the bending process may be performed in this order, or may be performed in the following order.
Connector housing forming step → cutting step → insertion step → bending step Further, another step may be provided before and after these steps and between each step. For example, a pressing step of performing a peak processing on the tip of the wire rod by pressing may be provided.

Further, the bending process may be a process of forming all the parts in one stage, or may be divided into a plurality of stages as follows.
(A) Connector housing forming process → cutting process → bending process 1 → insertion process → bending process 2
(B) Cutting process → Connector housing forming process → Bending process 1 → Inserting process → Bending process 2

  Further, the “wire aggregate” is a collection of metal wires that are cut and used as the material of the male terminal. For example, a metal wire wound around a reel corresponds to this.

(4) In the connector housing forming step of the connector manufacturing method according to the present invention, the through hole is formed along a direction inclined with respect to a connection direction of the power supply female terminal and the power supply male terminal. To do.

  In this method, the through hole into which the male terminal is inserted is formed along a direction inclined with respect to the connecting direction of the female terminal and the male terminal. Therefore, when the connector and the mating connector are connected, the male terminal is pushed by the female terminal due to friction (friction between the female terminal and the male terminal) or displacement (position displacement of the female terminal with respect to the male terminal position). Even in this case, the male terminal is pressed against the inner surface of the through hole. As a result, since the sliding movement of the male terminal along the through hole is suppressed, the male terminal is not easily pushed out from the through hole of the wall portion.

(connector)
The connector 1 includes a plurality of male terminals (a signal transmission male terminal 31, a signal transmission male terminal 32, and a power supply male terminal 33) and a connector housing 2 (see FIGS. 1 to 4). A substrate 4 is installed inside the connector 1. The connector 1 is electrically connected to both the external mating connector 5 and the internal substrate 4. Further, the connection direction E of the plurality of female terminals and the plurality of male terminals is a direction along the surface of the substrate 4.

  In the connector 1, each male terminal is attached to the substrate 4 by SMT (Surface Mount Technology) (see FIG. 4), and each male terminal is soldered on the surface side of the substrate 4. Has been. Each male terminal may be attached to the substrate by a pin insertion type. Specifically, the male terminal may be soldered on the back surface side of the substrate after the lead portion (substrate connection portion) has penetrated the substrate. In FIG. 4 and the like, solder is omitted.

(Connector housing)
The connector housing 2 is made of a synthetic resin material, and includes a main body portion 21, a wall portion 22, and a cover housing 26 (see FIG. 4). Moreover, in the connector housing 2, the main-body part 21, the wall part 22, and the cover housing 26 are separate articles. However, these may be formed integrally.

(Wall)
First, the wall portion 22 will be described. The wall portion 22 is a plate-like member that supports a plurality of male terminals. The wall 22 is disposed inside the main body 21 and is attached to the substrate 4 (see FIG. 4). The wall portion 22 has a plurality of through holes (see FIG. 5A). The “plurality of through holes” include a plurality of through holes 23, a plurality of through holes 24, and a plurality of through holes 25. The plurality of through holes are arranged in three rows, the plurality of through holes 23 are arranged in the first row (the uppermost row in FIG. 5A), and the plurality of through holes are arranged in the second row. A plurality of through holes 25 are arranged in the third row of holes 24.

  A male terminal is inserted into each through hole in the wall portion 22. Specifically, the signal transmission male terminal 31 is inserted into the through hole 23, the signal transmission male terminal 32 is inserted into the through hole 24, and the power source male terminal 33 is inserted into the through hole 25 ( (See FIG. 4).

  Moreover, the through-hole 23, the through-hole 24, and the through-hole 25 are not arrange | positioned on the straight line along the up-down direction in Fig.5 (a). For example, when attention is paid to the through holes at the left ends, the through holes 24 are located to the left with respect to the positions of the through holes 23, and the through holes 25 are located to the left of the positions of the through holes 24. doing. Therefore, in a state where a plurality of male terminals are inserted into the wall portion 22, the signal transmission male terminal 31, the signal transmission male terminal 32, and the power supply male terminal 33 do not overlap in plan view (top view) ( (See FIG. 11 (a)).

  In addition, three rows of groove portions 22d are formed on both surfaces of the wall portion 22 (see FIGS. 5A and 5B). Each of the groove portions 22d is composed of two upper and lower inclined surfaces, and each inclined surface is inclined 45 degrees with respect to the direction along the surface of the substrate 4. Each of the plurality of through-holes is formed so as to open at the position of the groove 22d on both surfaces (front surface and rear surface) of the wall portion 22 (see FIG. 5C).

  The through hole 23, the through hole 24, and the through hole 25 are formed to support the signal transmission male terminal 31, the signal transmission male terminal 32, and the power source male terminal 33, respectively. Moreover, the through-hole 23, the through-hole 24, and the through-hole 25 are formed along the direction inclined with respect to the connection direction E of a female terminal and a male terminal (refer FIG.4 and FIG.5 (c)). . The shape of each through hole is a quadrangle over the entire length. Of the inner surfaces of the through holes, the upper inner surface (upper side in FIG. 13) is defined as a contact surface (contact surface 23s, contact surface 24s, contact surface 25s) (see FIG. 13).

  FIG. 5C shows only the BB ′ cross section of FIG. 5A (that is, only the cross section of the through hole 25). However, as shown in FIG. The shape of 24 is the same as that of the through hole 25 in FIG.

(About through holes)
The through hole will be described in more detail. In addition to not being parallel to the connection direction E, the formation direction of the through holes (through hole 23, through hole 24, and through hole 25) is preferably not perpendicular to the connection direction E. That is, the angle between the formation direction of the through hole and the connection direction E (hereinafter, this angle is referred to as the formation angle; see angle α in FIG. 5C) is in the range of 1 to 89 degrees. Is desirable. In the present embodiment, the formation angle is 45 degrees.

  When the formation angle is close to 0 degrees, the connection direction E and the formation direction of the through hole substantially coincide with each other, so that the male terminal is easily pulled out. On the other hand, when the formation angle is close to 90 degrees, it is difficult to insert the male terminal. Further, when the forming angle is close to 90 degrees, the length of the insertion portion of the male terminal (the portion inserted into the wall portion) becomes long, so that the wall portion is arranged in the height direction (vertical direction in FIG. 5B). It will be necessary to make it longer. As a result, the connector becomes large. From the above, it is more desirable that the formation angle of the through hole is in the range of 20 degrees to 70 degrees. The formation angle of the through hole may be 0 degree or 90 degrees.

Moreover, the part (part in which the wall part 22 and the board | substrate 4 are accommodated) in which internal space 21s is formed among the main-body parts 21 is opened toward the downward direction (refer FIG.7 (c)). Further, the two side wall portions 21w and the side wall portion 21v are formed with protruding portions 21g (see FIGS. 6 and 7). The protruding part 21g protrudes in the direction along the surface of the substrate 4 from the two side wall parts 21w and the side wall part 21v. The positional relationship between the cover housing 26 described later and the main body portion 21 is determined by the protruding portion 21g.

And the insertion part 31b is arrange | positioned along the direction inclined with respect to the connection direction E inside the through-hole 23 (refer FIG.4 and FIG.12 (b)).

  The terminal connection part 31c is a part which protrudes from the wall part 22 and is connected to a female terminal (refer FIG.4 and FIG.12 (b)). The terminal connection portion 31c is formed continuously from the inclined portion 31n. Further, the terminal connection portion 31 c is arranged in the connector 1 so that the axial direction thereof is along the connection direction E. That is, the signal transmission male terminal 31 is formed along the connection direction E on the rear side (E2 side) in the connection direction from the wall portion 22.

  Further, as described above, the substrate hole insertion portion 31 d and the intermediate portion 31 m are solder-connected to the substrate 4.

  In this embodiment, the male terminal and the board are electrically connected both at the board hole insertion part and the middle part of the male terminal, but these electrical connections are made only at the board hole insertion part. Alternatively, it may be performed only in the middle part.

In addition, the inclined portion 31n extends from a position on the most rear side in the connection direction E in the intermediate portion 31m. Further, the inclined portion 31n extends rearward with respect to the connection direction E from the intermediate portion 31m. Here, the inclination part 31n “ extends rearward with respect to the connection direction” means that the inclination part 31n and the intermediate part 31m are based on a virtual plane perpendicular to the connection direction E (see the plane S in FIG. 10). It is shown that the inclined portion 31n extends from the boundary portion to the rear side instead of the front side (located in the rear region). The "extend and the rear side with respect to the connecting direction" inclination portion is not included in "extending Ru direction perpendicular to the connection direction E" that inclined portion.

  In the signal transmission male terminal 31, all of the board hole insertion part 31d, the intermediate part 31m, the inclined part 31n, and the terminal connection part 31c are connected to one virtual plane R (the connection direction E and the surface of the board 4). The plane is parallel to both directions perpendicular to the plane (see plane R in FIG. 10). Similarly, the male terminal 32 for signal transmission and the male terminal 33 for power supply are located on the virtual plane R. In this embodiment, when attention is paid to one male terminal, the entire male terminal is located on the virtual plane R, but the form of the male terminal is not limited to this, Only a part may be located on the virtual plane R, and the other part may not be located on the virtual plane R.

  In the present configuration, the inclined portion 31n is formed along the direction inclined with respect to the connection direction E, and the terminal connection portion 31c is formed along the connection direction E. In this connection, the signal transmission male terminal 31 is bent at a position between the inclined portion 31n of the signal transmission male terminal 31 and the terminal connection portion 31c. In addition, in the state where the signal transmission male terminal 31 is attached to the substrate 4, the angle of the inclined portion 31 n with respect to the surface of the substrate 4 is equal to the formation angle (angle α) of the through hole 23.

(Assembly method)
Next, a method for assembling the connector 1 will be described. First, the connector housing 2 is formed by injection molding (connector housing forming step). In this step, a plurality of through holes (through hole 23, through hole 24, and through hole 25) are formed in the wall portion 22 along the direction inclined in the connection direction E.

  Next, a wire material (wired male terminal) as a material for the male terminal is prepared. Specifically, a metal wire wound on a reel (wire aggregate; not shown) is cut to cut the wire (cutting step). At this time, three types of lengths (each length of the signal transmission male terminal 31, the signal transmission male terminal 32, and the power supply male terminal 33) are formed. And the front-end | tip part of the both ends of the obtained wire is sharpened by press work (press process).

  In the cutting step, as the material of the power supply male terminal 33, a material (copper 97.5%, iron 2 .2) having higher conductivity than the signal transmission male terminal 31 and the signal transmission male terminal 32 (Nanasan brass). 3%, zinc 0.1%, phosphorus 0.1% copper alloy). In the cutting process, when the material to be cut is changed (from the signal transmission male terminal material to the power supply male terminal material, or from the power supply terminal material to the signal transmission male terminal material). In this case, the reel on which the wire is wound is replaced with a reel on which a wire made of another material is wound, and the wire is cut.

  The three types of metal wires that have undergone the cutting process and the pressing process become a linear male terminal 31p, a linear male terminal 32p, and a linear male terminal 33p, respectively (see FIG. 12A). Further, the linear male terminal 31p, the linear male terminal 32p, and the linear male terminal 33p are respectively a signal transmission male terminal 31, a signal transmission male terminal 32, and a power supply male terminal before bending. This corresponds to 33. Note that there is no need for a pressing step.

Next, the wire (the linear male terminal 31p, the linear male terminal 32p, and the linear male terminal 33p) is inserted into the through holes (the through hole 23, the through hole 24, and the through hole 25) of the wall portion 22. (Insertion step; see FIG. 12A).
At this time, each of the linear male terminal 31p, the linear male terminal 32p, and the linear male terminal 33p is pressed into the through hole (pressed with a strong pressure).

  Next, a bending process is performed with respect to the linear male terminal 31p, the linear male terminal 32p, and the linear male terminal 33p (bending process). Specifically, the linear male terminal 31p shown in FIG. 12B will be described. The linear male terminal 31p is bent at three locations D1, D2, and D3 shown in FIG. 12B. To implement. By this bending step, a substrate hole insertion portion 31d, an intermediate portion 31m, an inclined portion 31n (insertion portion 31b), and a terminal connection portion 31c are formed. Bending is similarly performed on the linear male terminal 32p and the linear male terminal 33p. A male terminal is manufactured through the cutting step and the bending step.

  FIG. 12B shows a state in which a plurality of male terminals are attached to the wall portion 22. The wall portion in this state is referred to as a “wall portion with a male terminal”. The direction of the terminal connection portion is the direction along the connection direction E in a state where the wall portion with the male terminal is attached to the main body portion 21 by bending the male terminal on the terminal connection portion side (D1 portion) of the wall portion 22. It becomes.

  In addition, when the male terminal is bent at the position of D3 in FIG. 12B, the direction of the board hole insertion portion is directed to the surface of the board 4 in a state where the wall portion with the male terminal is attached to the main body portion 21. The direction is perpendicular to the direction along.

  In the present embodiment, the male terminal is bent at three locations D1, D2, and D3, but is not limited to such a bending method. For example, the male terminal may be bent at two locations D1 and D3 (there may be no intermediate portion). Further, the male terminal is bent at only one location (D1) in the vicinity of the wall portion 22, but the male terminal may be bent at two locations sandwiching the wall portion 22.

  Next, the wall portion with the male terminal is attached to the substrate 4 (substrate attachment step). The substrate in this state is referred to as a “walled substrate” (see FIGS. 10 and 11). As this attachment method, both may be adhered by an adhesive, or both may be fixed by screwing. Moreover, a recessed part and a convex part may be formed in both, and both may be fixed by these connection.

  The solder connection between the plurality of male terminals and the substrate in the substrate mounting step will be described in more detail. First, a solder paste is printed on the surface of the substrate 4 (the surface of the metal film 43). Then, on the solder paste, a plurality of male terminals are arranged on the surface of the substrate 4 using an automatic mounting machine (mounter or inserter) (the substrate hole insertion portion is inserted into the substrate through hole 42). Then, the substrate 4 on which the wall portion and the male terminal are mounted is passed through a reflow furnace and heated to about 250 degrees Celsius, thereby melting the solder and soldering the male terminal to the surface of the substrate 4. Thereafter, cooling is performed.

  Next, the main body 21 is attached to the substrate with the wall, and then the cover housing 26 is attached to the main body 21 (housing assembly process). The connector 1 is obtained after the housing assembly process. As described above, the assembly of the connector 1 is completed.

  Note that these steps may be performed in a plurality of stages. For example, after carrying out to the bending process in the above order, it is shipped in the state of a wall portion with a male terminal, and the remaining assembly processes (board mounting process and housing assembly process) are performed in other assembly companies. Good. In addition, an operator may perform part or all of the above steps (connector housing forming step, cutting step, pressing step, inserting step, bending step, board attaching step, housing assembling step) manually. It may be performed automatically using an automatic machine.

  As described above, in the present embodiment, since the male terminal of the connector 1 is manufactured using a wire, it is not necessary to press the metal plate. Therefore, the manufacturing cost of the metal plate pressing metal mold becomes unnecessary, and the manufacturing cost of the male terminal can be reduced. In addition, since a metal plate pressing metal mold is not required, the metal mold manufacturing period is unnecessary, and the manufacturing time of the entire connector can be shortened.

(effect)
Next, effects obtained by the connector 1 according to the present embodiment and the method for manufacturing the connector 1 will be described. The connector 1 according to the present embodiment is for the counterpart connector 5 having a plurality of power supply female terminals 73 and a plurality of signal transmission female terminals (a signal transmission female terminal 71 and a signal transmission female terminal 72). A plurality of power supply female terminals 73 and a plurality of power supply male terminals 33 that are electrically connected to the power supply 8 and are manufactured using a wire, and a wire. A plurality of signal transmission male terminals (signal transmission male terminal 31, signal transmission, which are electrically connected to a plurality of signal transmission female terminals and used for transmission of electrical signals. The connector housing 2 includes a male terminal 32), a plurality of power supply male terminals 33, and a wall portion 22 that supports the plurality of signal transmission male terminals. Each of the plurality of power supply male terminals 33 and the plurality of signal transmission male terminals is inserted into a through hole (through hole 23, through hole 24, or through hole 25) formed in the wall portion 22. Each of the male terminal for signal 33 and the plurality of male terminals for signal transmission protrudes from the insertion portion (insertion portion 31b, insertion portion 32b, or insertion portion 33b) inserted into the through hole and the wall portion 22, and is used for power supply. The terminal connection part (terminal connection part 31c, terminal connection part 32c, or terminal connection part 33c) connected to the female terminal 73 or the signal transmission female terminal is formed, and the material of the power supply male terminal 33 is The conductivity is higher than the material of the male terminal for signal transmission.

  In this configuration, since the electrical conductivity of the material of the power supply male terminal 33 is higher than that of the material of the signal transmission male terminal (the signal transmission male terminal 31 and the signal transmission male terminal 32), the power supply male terminal 33 is used. There is no need to change the terminal shape between the terminal and the male terminal for signal transmission. And since the difference between the male terminal for power supply and the male terminal for signal transmission is only the material, for example, by replacing the reel around which the wire is wound, the manufacture of the male terminal for power supply and the signal transmission The production of the male terminal can be easily switched. Therefore, both the male terminal for power supply and the male terminal for signal transmission can be manufactured by the same manufacturing process.

  Moreover, according to this structure, the metal terminal press metal mold | die becomes unnecessary by manufacturing a male terminal using a wire. Therefore, the male terminal can be manufactured in a short period of time, and the manufacturing cost of the male terminal is reduced.

  In addition, when a male terminal is manufactured by press working on a metal plate, the portion excluding the male terminal becomes scrap, but in this configuration, the male terminal is manufactured using a wire material, so that scrap is generated. Can be suppressed. Therefore, useless material costs can be reduced.

  In the connector 1, each through hole is formed along a direction inclined with respect to the connection direction E of the power supply female terminal 73 and the power supply male terminal 33.

  In this configuration, each through hole into which the male terminal is inserted has a female terminal (a female terminal for signal transmission 71, a female terminal for signal transmission 72, a female terminal for power supply 73) and a male terminal (a male terminal for signal transmission 31, It is formed along a direction inclined with respect to the connection direction E of the signal transmission male terminal 32 and the power supply male terminal 33). For this reason, when the connector 1 and the mating connector 5 are connected, the male terminal is moved by the female terminal due to friction (friction between the female terminal and the male terminal) or displacement (position displacement of the female terminal with respect to the male terminal position). Even if it is pushed, the male terminal is pressed against the inner surface (contact surface 23s, contact surface 24s, contact surface 25s) of the through hole. As a result, since the sliding movement of the male terminal along the through hole is suppressed, the male terminal is hardly pushed out from the through hole of the wall portion 22.

  Moreover, the manufacturing method of the connector 1 according to the present embodiment includes a plurality of power supply female terminals 73 and a counterpart side having a plurality of signal transmission female terminals (signal transmission female terminals 71 and signal transmission female terminals 72). (I) a plurality of power supply female terminals 73, a plurality of power supply male terminals 33 connected electrically to the power supply 8, and (ii) a plurality of power supply female terminals 73 A method of manufacturing a connector 1 having a plurality of male terminals for signal transmission, which is electrically connected to a female terminal for signal transmission and is used for transmission of electric signals, A cutting step of cutting a certain wire and a wire that is a material of the signal transmission male terminal from the wire assembly, a plurality of power supply male terminals 33, and a wall portion 22 that supports the plurality of signal transmission male terminals. Connector housing forming connector housing 2 having Forming process, insertion process of inserting each wire into a through-hole (through-hole 23, through-hole 24, or through-hole 25) formed in the wall 22, and bending each wire to penetrate An insertion portion (insertion portion 31b, insertion portion 32b, or insertion portion 33b) to be inserted into the hole and a terminal connection portion (terminal) protruding from the wall portion 22 and connected to the power supply female terminal 73 or the signal transmission female terminal A bending step of forming the connection portion 31c, the terminal connection portion 32c, or the terminal connection portion 33c). In the cutting step, a material having higher conductivity than the material of the signal transmission male terminal 33 is used as the material of the power source male terminal 33.

  In this method, the conductivity of the material of the power supply male terminal 33 is higher than the conductivity of the material of the signal transmission male terminal (signal transmission male terminal 31, signal transmission male terminal 32). There is no need to change the terminal shape between the male terminal for power supply and the male terminal for signal transmission. Since the difference between the power male terminal and the signal transmission male terminal is only the material, for example, by exchanging a reel around which a wire is wound, the manufacture of the power male terminal 33 and the signal transmission are performed. The production of the male terminal can be easily switched. Therefore, both the male terminal for power supply and the male terminal for signal transmission can be manufactured by the same manufacturing process.

  Moreover, in this method, a metal terminal is not required for manufacturing a male terminal using a wire. Therefore, the male terminal can be manufactured in a short period of time, and the manufacturing cost of the male terminal is reduced.

  In addition, when a male terminal is manufactured by pressing a metal plate, the portion excluding the male terminal becomes scrap. However, in this method, since the male terminal is manufactured using a wire, scrap is generated. Can be suppressed. Therefore, useless material costs can be reduced.

  In the connector housing forming step of the manufacturing method of the connector 1 according to this embodiment, the through hole is formed along the direction inclined with respect to the connection direction E of the power supply female terminal and the power supply male terminal.

  In this method, each through hole into which the male terminal is inserted has a female terminal (a female terminal for signal transmission 71, a female terminal for signal transmission 72, a female terminal for power supply 73) and a male terminal (a male terminal for signal transmission 31, It is formed along a direction inclined with respect to the connection direction E of the signal transmission male terminal 32 and the power supply male terminal 33). For this reason, when the connector 1 and the mating connector 5 are connected, the male terminal is moved by the female terminal due to friction (friction between the female terminal and the male terminal) or displacement (position displacement of the female terminal with respect to the male terminal position). Even if it is pushed, the male terminal is pressed against the inner surface (contact surface 23s, contact surface 24s, contact surface 25s) of the through hole. As a result, since the sliding movement of the male terminal along the through hole is suppressed, the male terminal is hardly pushed out from the through hole of the wall portion 22.

  From the viewpoint of shortening manufacturing time and manufacturing cost, it is desirable to manufacture a male terminal using a wire. However, regarding the power supply terminal, in order to reduce the amount of heat generated at the power supply terminal, for example, it is necessary to increase the cross-sectional area of the power supply terminal. Therefore, when manufacturing a male terminal for signal transmission using a wire, and manufacturing a male terminal for power supply by pressing a metal plate, a manufacturing facility (apparatus etc.) dedicated to each male terminal. )Is required. However, it is desirable to be able to manufacture both male terminals using the same or similar manufacturing equipment. By manufacturing the connector 1 as described above, each male terminal can be manufactured using the same or similar manufacturing equipment.

  Moreover, when manufacturing two types of male terminals, ie, a power source male terminal and a signal transmission male terminal, by pressing the metal plate, (1) using the same material, manufacturing two types of male terminals of different sizes And (2) the case where the conductivity of the power supply male terminal is made larger than that of the signal transmission male terminal using different materials. In the case of (1), two types of manufacturing equipment and manufacturing process are required. In the case of (2), if each material is appropriately selected, the same or similar manufacturing equipment and manufacturing process can be used. Two types of male terminals can be manufactured. However, even in the case of (2), as in the case of (1), scrap is generated in the manufacturing process of the male terminal. On the other hand, in the present invention, the generation of scrap is suppressed by manufacturing all the male terminals from the wire. Therefore, according to the connector 1, the manufacturing cost can be reduced in comparison with either case (1) or (2).

  From the viewpoint of reducing the amount of heat generated in the male terminal, it is also effective to shorten the terminal length in addition to increasing the cross-sectional area. In the connector 1, by using the shortest third-stage male terminal among the plurality of male terminals as the power supply male terminal, the amount of generated heat can be efficiently reduced.

  In the connector 1, the male terminal is difficult to come off in the direction pushed by the female terminal when the two connectors are connected, that is, the E1 side in the connection direction E. For example, if the male terminal is bent on the E1 side of the wall portion 22, the male terminal is hardly pulled out to the E2 side in the connection direction E.

  Further, according to the connector 1, the male terminal (the male terminal 31 for signal transmission, the signal transmission) is transmitted from the through hole (through hole 23, through hole 24, through hole 25) by a simple means of bending the male terminal. The structure in which the male terminal 32 for power supply and the male terminal for power supply 33) are difficult to be removed can be realized.

  Further, in the manufacture of the connector 1, since the male terminal is manufactured from the wire without using the metal plate pressing mold, it is more flexible than the case where the male terminal is manufactured by pressing the metal plate. Connector specifications can be changed.

  In addition, as described above, in the present embodiment, since the male terminal is made from a wire, no scrap is generated when the male terminal is manufactured. In many cases, scrap is plated, and in that case, the transaction price of the scrap becomes low. Therefore, it is desirable from the viewpoint of manufacturing cost that the amount of generated scrap is reduced.

  As described above, the manufacturing cost of the connector according to the present embodiment is lower than that in the case where the male terminal is manufactured by pressing the metal plate. This cost reduction effect becomes more prominent as the number of poles (number of male terminals) increases.

  As described above, the connector 1 is a type of connector in which the connection direction E is the same as the direction along the surface of the substrate 4. In such a type of connector, it is conceivable that the male terminal is bent vertically at one place (see the male terminal 931 according to the reference example shown in the broken line part in FIG. 12B). Compared to such a male terminal 931, in the connector 1 of this embodiment, the terminal length of the signal transmission male terminal 31 is shortened (the same applies to the signal transmission male terminal 32 and the power supply male terminal 33). Therefore, compared with the male terminal 931, the electrical resistance of the male terminal is reduced, and the amount of heat generated at the male terminal is reduced, so that a decrease in connector performance can be prevented. In addition, by shortening the terminal length of the male terminal, the delay of the high-frequency electrical signal can be reduced when the male terminal is a signal transmission terminal.

  In addition, when the through hole is formed along the connection direction E, in order to suppress the movement of the male terminal manufactured from the wire, the wall portion is thickened and the through hole is lengthened, and the action of the friction force Need to be increased. On the other hand, according to this configuration, with respect to the connection direction E, the inner surface (contact surface 23s, contact surface 24s, contact) of the through hole is formed on the E1 side of the terminal connection portion (terminal connection portion 31c, terminal connection portion 32c, terminal connection portion 33c). Since the surface 25s) is positioned, the movement of the male terminal is more significantly suppressed by the through-holes in the wall than in the case where the through-hole formation direction coincides with the connection direction E. Therefore, according to this configuration, the movement of the male terminal can be suppressed without increasing the thickness of the wall portion.

  As described above, the connector 1 is a connector of a type in which the connection direction E and the substrate 4 are parallel, but the connector is not limited to such a type. For example, the connection direction E and the surface of the substrate 4 And may be vertical. In this case, for example, the male terminal may be bent at two locations D1 and D2 or at two locations sandwiching the wall 22.

  In the above-described embodiment, the inclined portion is inclined with respect to the connection direction in the side view (see FIG. 4), but the inclined portion is inclined with respect to the connection direction in the plan view (top view). May be. Similarly, the through hole may be inclined with respect to the connection direction in plan view.

Note that the board hole insertion portion, the intermediate portion, the inclined portion, and the terminal connection portion may not be located on the virtual plane R. Further, the inclined portion may not extend from a position on the most rear side (E2 side) in the connection direction in the intermediate portion, and may extend from a position on the most front side (E1 side) of the intermediate portion.

Similarly to the above embodiment, the through holes 423, the through holes 424, and the through holes 425 are not arranged on a straight line in the vertical direction in FIG. Therefore, in a state where a plurality of male terminals are inserted into the wall portion 422, the signal transmission male terminal 31, the signal transmission male terminal 32, and the power supply male terminal 33 do not overlap in plan view (top view).
