Description
Technical Field
The present invention relates to a cable connector in which a cable is drawn in a direction intersecting with a connector insertion/removal direction, and a substrate connector connected to the cable connector.
Background
The cable connector in which the drawing direction of the cable is set to a direction intersecting the insertion and extraction direction of the connector has the following advantages: even in a situation where a large space cannot be secured above the substrate, the cable and the substrate can be easily connected via the connector.
For example, consider the following case: a connector for a substrate having an insertion hole opened upward is mounted on a surface of a horizontally placed substrate, and the connector for the substrate and the connector for the cable are connected by inserting an insertion portion of the connector for the cable into the insertion hole of the connector for the substrate from the top down. In this case, if a cable connector in which the cable is drawn in the same direction as the insertion and removal direction of the connector is used, both the insertion and removal direction of the connector and the cable drawing direction are perpendicular to each other. Therefore, when the cable connector is connected to the substrate connector, the cable extends upward from the substrate. Therefore, it is difficult to route cables in a situation where a large space cannot be secured above the substrate. On the other hand, when a cable connector in which the cable is drawn out in a direction orthogonal to the insertion and extraction direction of the connector is used, the insertion and extraction direction of the connector is the vertical direction, and the cable is drawn out in the horizontal direction. Therefore, when the connector for a cable is connected to the connector for a substrate, the cable extends along the surface of the substrate. Therefore, the cables can be easily wired in a state where a large space cannot be secured above the substrate.

Patent document 2: japanese patent laid-open publication No. 2018-160408
Fig. 3 of patent document 1 describes an electrical connector and a mating connector (20) connected to the electrical connector. As shown in the figure, the insertion/removal direction of the electrical connector with respect to the mating connector (20) is a vertical direction, and the drawing directions of the cables (C1, C2) attached to the housing main body (1) of the electrical connector are horizontal directions. An electrical connector is connected to a mating connector (20) by fitting a contact arrangement section (21) formed on the mating connector (20) into a receiving recess (7) formed in a projection (9) of a housing body (1) of the electrical connector.
However, the depth of the receiving recess (7) in the electrical connector described in patent document 1 and the height of the contact arrangement section (21) in the mating connector (20) are both small. Therefore, the fitting between the contact arrangement portion (21) and the receiving recess (7) is shallow, and the effective fitting length between the terminals of the electrical connector and the terminals of the mating connector (20) is short. A connector having a short effective fitting length has low durability against prying. For example, when the leading end side of the cable led out in the horizontal direction from the housing of the connector moves in the horizontal direction or the vertical direction and thus the connector is pried, the connector is misaligned with respect to the counterpart connector, and there is a concern that it is difficult to maintain the contact of the terminal of the connector with the terminal of the counterpart connector.
On the other hand, fig. 3 of patent document 2 describes a coaxial connector having an L-shaped inner terminal (20). As shown in fig. 1 of the above-mentioned document, the L-shaped inner terminal (20) has a pressure-bonding section (22) to which the core wire (2) of the coaxial cable (1) is connected and a body section (21) which is in contact with the terminal of the mating connector, the pressure-bonding section (22) is elongated in the horizontal direction, and the body section (21) is elongated in the vertical direction. In this way, when the terminals of the connector are formed in an L shape, the length of the portion extending in the vertical direction can be increased, thereby increasing the effective fitting length between the terminals of the connector and the terminals of the mating connector, and improving the durability against prying.
However, if the terminals of the connector are integrally formed in an L-shape, the housing that houses the L-shaped terminals must be divided into a plurality of pieces. For example, in a coaxial connector described in patent document 2, as shown in fig. 2 of the document, a portion that houses an L-shaped inner terminal (20) is divided into a cylindrical portion (41) and a cover (60). In the case where the housing is divided into a plurality of parts, the parts constituting the housing must be assembled when assembling the connector. Therefore, the number of assembly steps increases, and workability in assembling the connector is deteriorated.

As shown in fig. 2, the cable connector 1 includes a plurality of terminals 5 and a housing 31 that houses the terminals 5. Each terminal 5 is formed of a conductive material such as a copper alloy. The housing 31 is formed of a nonconductive material such as resin. The cable connector 1 in the present embodiment has 30 terminals 5. These terminals 5 are arranged in two stages in the housing 31, and 15 terminals 5 are aligned in a row in the left-right direction in each stage.
Fig. 3 shows a state in which the first terminal piece 11 and the second terminal piece 21 forming one terminal 5 are arranged in a portion from the upper side to the front side of the housing 31 as viewed from the upper left rear side. Fig. 4 shows a state in which the second terminal piece 21 in fig. 3 is viewed from the lower left front. Fig. 5 shows a cross section of the second terminal piece 21 as viewed from the direction of arrow V-V in fig. 4.
Each terminal 5 has a first terminal piece 11 elongated in the front-rear direction and a second terminal piece 21 elongated in the up-down direction. Each terminal 5 is formed in an L-shape in side view by connecting the tip end side of the first terminal piece 11 and the upper end side of the second terminal piece 21 to each other.
The first terminal piece 11 and the second terminal piece 21 are separate members. In each terminal 5, the first terminal piece 11 and the second terminal piece 21 can be separated from each other as shown in fig. 3. In a state where the terminal 5 is housed in the terminal housing portion 40, as shown in fig. 2, the first terminal piece 11 and the second terminal piece 21 are coupled to each other.
As shown in fig. 3, the first terminal piece 11 is a substantially rod-shaped member, and a cable connection portion 12 for connecting a cable 80 is provided on a rear end side (base end side) of the first terminal piece 11. The cable connection portion 12 includes a conductor cylindrical portion 13 for crimping the conductor 81 of the cable 80 and an insulator cylindrical portion 14 for crimping the insulator 82 of the cable 80.
Further, a coupling portion 15 for coupling to the second terminal piece 21 is provided on the leading end side (trailing end side) of the first terminal piece 11. The coupling portion 15 is formed by a front-side contact piece 16. The front contact piece 16 is formed in a flat plate shape that protrudes forward at the front end portion of the first terminal piece 11 and spreads in the vertical direction and the front-rear direction.
In addition, in the first terminal piece 11 of each terminal 5, a locking protrusion 17 protruding outward in the vertical direction from a portion between the cable connection portion 12 and the connection portion 15 is provided.

In each upper contact piece 24, a lower end side (base end side) is supported by the base 22, and an upper end side (tail end side) is a free end. Thus, each upper contact piece 24 has a cantilever beam configuration. The upper end portions of the pair of upper contact pieces 24 are close to each other, and the front contact piece 16 of the first terminal piece 11 is inserted therebetween. When the front side contact 16 is inserted between the pair of upper side contacts 24, the pair of upper side contacts are pressed by the front side contact 16 and elastically deformed so as to be separated from each other in the left-right direction, and press the left and right surfaces of the front side contact 16 to sandwich the front side contact 16. Thereby, the first terminal piece 11 and the second terminal piece 21 are electrically connected. The pair of upper guards 25 has a function of protecting the pair of upper contact pieces 24.
Further, a contact portion 26 that contacts the terminal 62 of the substrate connector 61 is provided on the lower end side (tail end side) of the second terminal piece 21. The contact portion 26 has a pair of lower contact pieces 27 and a pair of lower guard portions 28. The pair of lower contact pieces 27 are each formed in a plate shape extending in the vertical direction and are arranged to face each other in the left-right direction. In each lower contact piece 27, the upper end side (base end side) is supported by the base 22, and the lower end side (tail end side) is a free end. Thus, each lower contact piece 27 has a cantilever beam configuration. The lower end portions of the pair of lower contact pieces 27 are close to each other, and the contact portion 63 of the terminal 62 of the board connector 61 is inserted therebetween. When the contact portion 63 is inserted between the pair of lower contact pieces 27, the contact portions 63 press the lower contact pieces 27 to be elastically deformed so as to be separated from each other in the left-right direction, and the left and right surfaces of the contact portion 63 are pressed to sandwich the contact portion 63. Thereby, the terminal 5 of the cable connector 1 and the terminal 62 of the board connector 61 are electrically connected. The pair of lower protection portions 28 has a function of protecting the pair of lower contact pieces 27.
As shown in fig. 4, a locking piece 29 protruding forward from the front surface of the second terminal piece 21 of each terminal 5 is provided. As will be described later, the second terminal piece 21 of each terminal 5 is fixed in the second terminal piece housing 42 of the housing 31 by the locking piece 29.
The second terminal pieces 21 of all the terminals 5 included in the cable connector 1 have the same shape, and the lengths of the second terminal pieces 21 in the vertical direction are equal to each other. These second terminal pieces 21 can be formed by, for example, subjecting copper alloy plates cut into the same shape to the same bending process.

The first terminal piece 11 inserted into each of the first terminal piece accommodating portions 41 on the upper side is fixed in the first terminal piece accommodating portion 41 on the upper side by the locking protrusion 17 being locked in the upper locking hole 48. Further, since each of the upper locking holes 48 penetrates the upper wall portion 32, the worker who assembles the cable connector 1 can confirm that each of the locking protrusions 17 is locked to the upper locking hole 48, that is, each of the first terminal pieces 11 is reliably inserted into the upper first terminal piece accommodating portion 41 and fixed, by observing the housing 31 from above.
On the other hand, in the case 31, when the first terminal piece 11 is inserted into each of the first terminal piece accommodating portions 41 on the lower side, the locking convex portion 17 provided in the first terminal piece 11 is directed downward. The first terminal piece 11 inserted into each first terminal piece housing portion 41 on the lower side is fixed in the first terminal piece housing portion 41 on the lower side by the locking protrusion 17 being locked in the lower locking hole 49. Further, since the lower locking holes 49 penetrate the lower wall portion 33, the worker who assembles the cable connector 1 can confirm that the locking protrusions 17 are locked to the lower locking holes 49, that is, that the first terminal pieces 11 are reliably inserted into and fixed to the first terminal piece accommodating portions 41 arranged on the lower side, by looking down the housing 31.

Specifically, in a state where the second terminal pieces 21 are arranged in the second terminal piece accommodating portions 42, the first terminal pieces 11 are inserted into the first terminal piece accommodating portions 41, so that the front side contact pieces 16 of the first terminal pieces 11 enter between the pair of upper side contact pieces 24 of the second terminal pieces 21, and the front side contact pieces 16 and the pair of upper side contact pieces 24 contact each other.
(connector for substrate)
Fig. 10 shows the substrate connector 61 as viewed from the top left and rear. Fig. 11 shows the substrate connector 61 as viewed from above. Fig. 12 shows a cross section of the substrate connector 61 as viewed in the direction of arrow XII-XII in fig. 11.
The substrate connector 61 includes a plurality of terminals 62 and a housing 65 that houses the terminals 62. Each terminal 62 is formed of a conductive material such as a copper alloy. The housing 65 is formed of a nonconductive material such as resin. The substrate connector 61 is formed, for example, by a method (insert molding) of inserting the plurality of terminals 62 into a mold and injecting resin around the terminals to mold the housing 65. The terminal 62 is a specific example of the "target terminal", and the housing 65 is a specific example of the "target housing".
As shown in fig. 10, the housing 65 of the substrate connector 61 is formed in a box shape having a lower plate portion 66, a front plate portion 67, a rear plate portion 68, a left plate portion 69, and a right plate portion 70. The housing 65 has an insertion recess 71 into which the lower portion (insertion portion 51) of the cable connector 1 is inserted. The insertion recess 71 is defined by the plate sections 66-70 and has an upper opening. Further, a notch 72 is formed in an upper portion of the rear plate portion 68.
As shown in fig. 11, the board connector 61 has 30 terminals 62 so as to correspond to the 30 terminals 5 of the cable connector 1. These terminals 62 are disposed in the insertion recess 71. The terminals 62 are divided into two rows, a front row and a rear row, and 15 terminals 62 are arranged in the left-right direction in each row. The 15 terminals 62 in the front row and the 15 terminals 62 in the rear row are arranged so as to correspond to each other in the front-rear direction. As shown in fig. 12, each terminal 62 is formed in an elongated plate shape elongated in the vertical direction, and the base end side of each terminal 62 is supported by the lower plate portion 66. The tail end of each terminal 62 projects upward. The tail end side of each terminal 62 is a contact portion 63 that contacts the contact portion 26 of the terminal 5 of the cable connector 1. Further, a circuit connection portion 64 connected to a circuit of the substrate is provided at a proximal end portion of each terminal 62. In addition, the heights of the upper ends of the 30 terminals 62 are equal to each other, and the positions of the contact portions 63 in the vertical direction are equal to each other.
In addition, a partition plate 73 that partitions between two terminals 62 adjacent to each other in the front-rear direction is provided in the insertion recess 71. That is, the terminals 62 arranged in the front row are separated from the terminals 62 arranged in the rear row by the partition 73. As shown in fig. 10, the partition plate 73 extends in the vertical direction and the horizontal direction, and the lower end portion of the partition plate 73 is supported by the lower plate portion 66. As shown in fig. 11, left end 73A of partition 73 is separated from left plate 69, and right end 73B of partition 73 is separated from right plate 70.
As shown in fig. 12, each terminal 62 is separated from each of the partition plate 73, the front plate 67, the rear plate 68, the left plate 69, and the right plate 70. The tail end of each terminal 62 is located below the upper edge of each of the partition 73, the front plate 67, the rear plate 68, the left plate 69, and the right plate 70. The front portion 71A is higher than the rear portion 71B on the bottom surface of the insertion recess 71.
As shown in fig. 10, a lock piece insertion portion 75 and a lock hole portion 76 are provided in the center portion of the front plate portion 67 in the left-right direction. Concave key portions 77 are provided on the left and right portions of the front plate portion 67, respectively.
As shown in fig. 1, when the cable connector 1 is connected to the substrate connector 61, the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 from above the substrate connector 61 while the convex key portion 58 is engaged with the concave key portion 77. After the insertion portion 51 is inserted into the insertion recess 71, the partition 73 provided in the insertion recess 71 enters the groove portion 54 provided in the insertion portion 51 of the housing 31 of the cable connector 1. After the insertion portion 51 enters the insertion recess 71, the lower portion of the front wall portion 34 of the cable connector 1 enters between the front plate portion 67 of the substrate connector 61 and the partition 73, the lower portion of the rear wall portion 35 of the cable connector 1 enters between the rear plate portion 68 of the substrate connector 61 and the partition 73, the lower portion of the left wall portion 36 of the cable connector 1 enters between the left plate portion 69 of the substrate connector 61 and the left end 73A of the partition 73, and the lower portion of the right wall portion 37 of the cable connector 1 enters between the right plate portion 70 of the substrate connector 61 and the right end 73B of the partition 73.
After the insertion portion 51 enters the insertion recess 71, the contact portion 63 of each terminal 62 of the board connector 61 passes through the terminal insertion hole 47 of the housing 31 of the cable connector 1, enters the second terminal piece housing portion 42, and contacts the contact portion 26 of the terminal 5 of the cable connector 1. Specifically, the contact portion 63 enters between the pair of lower contact pieces 27, and the contact portion 63 and the pair of lower contact pieces 27 contact each other.
After the insertion portion 51 enters the insertion recess 71, the lock piece 56 enters the lock piece insertion portion 75, and the lock protrusion 57 enters the lock hole 76 and is locked.
As described above, in the cable connector 1 according to the embodiment of the present invention, the terminals 5 each having an L-shape in side view are formed by the first terminal piece 11 and the second terminal piece 21 which are separable from each other, and the wall portions 32 to 37 and 43 to 45 of the housing 31 are integrated so as to be inseparable from each other. If the portions of the terminals 5 extending in the front-rear direction and the portions extending in the vertical direction cannot be separated from each other in the L-shaped side view, the terminals 5 cannot be mounted in the housing 31 in which the wall portions 32 to 37 and 43 to 45 are integrated so as not to be separated from each other. However, in the cable connector 1 according to the embodiment of the present invention, in each of the L-shaped terminals 5 in side view, the portion extending in the front-rear direction and the portion extending in the up-down direction are formed by the first terminal piece 11 and the second terminal piece 21 which are separable from each other. Therefore, when the terminals 5 are incorporated into the housing 31, the first terminal piece 11 and the second terminal piece 21 of each terminal 5 are separated from each other, whereby the terminals 5 having an L-shape in side view can be incorporated into the housing 31.
In this way, the first terminal piece 11 and the second terminal piece 21 which are separable from each other form the terminals 5 in the L shape in side view, and the housing 31 is formed in a structure in which the wall portions 32 to 37 and 43 to 45 are inseparably integrated, so that a process of assembling the components constituting the housing can be eliminated when assembling the cable connector 1. That is, in the conventional cable connector having the L-shaped terminal, the housing has a structure divided into a plurality of parts so that the terminal integrally formed in the L-shape can be incorporated into the housing. Therefore, when assembling the cable connector, a process of assembling the components constituting the housing is required. According to the cable connector 1 of the embodiment of the present invention, such a process of assembling the components constituting the housing can be eliminated.
In this way, when the cable connector 1 is assembled, the number of assembling steps of the cable connector can be reduced or the assembling work of the cable connector can be simplified by eliminating the step of assembling the members constituting the housing 31. Therefore, workability of assembling the cable connector can be improved. Specifically, the dealer of the cable connector 1 sells the cable connector 1 in a state where the second terminal piece 21 of each terminal 5 is fitted into the housing 31 of the cable connector 1. The user who purchases the cable connector 1 connects the cable 80 to each first terminal piece 11 only. Then, the first terminal pieces 11 are fitted into the housing 31, and the cable connector 1 can be assembled. That is, by performing the step of fitting the second terminal piece 21 into the housing 31 shown in fig. 9 (a) in advance and performing the step of fitting the first terminal piece 11 into the housing 31 shown in fig. 9 (B) when the cable connector 1 is actually used, the assembly work of the cable connector 1 can be simplified or the efficiency of the assembly work of the cable connector 1 can be improved.
In the embodiment of the present invention, each terminal 5 of the cable connector 1 has an L-shape, and each terminal 62 of the board connector 61 protrudes upward and is separated from each of the partition plate 73, the front plate 67, the rear plate 68, the left plate 69, and the right plate 70. According to this configuration, the length of the portion elongated in the vertical direction in each terminal 5 of the cable connector 1, that is, the length of the second terminal piece 21 in the vertical direction is increased, and the length of each terminal 62 of the substrate connector 61 in the vertical direction is increased, whereby the effective fitting length between each terminal 5 of the cable connector 1 and each terminal 62 of the substrate connector 61 can be increased. This can improve durability against prying.
Further, according to the embodiment of the present invention, by increasing the length of the portion (the second terminal piece 21) extending in the vertical direction in each of the L-shaped terminals 5 of the cable connector 1 and the length in the vertical direction of each of the terminals 62 of the board connector 61, the height of the board connector 61 can be increased while the contact between each of the terminals 5 and each of the terminals 62 is ensured, and the cable connector 1 can be largely separated from the surface of the board on which the board connector 61 is mounted in a state where the cable connector 1 is connected to the board connector 61, as shown in fig. 13. Thus, the cable connector 1 and the board connector 61 according to the present embodiment can be easily applied to a product requiring potting (potting) of a board. More specifically, for example, in a substrate mounted on a home appliance or the like, potting is sometimes performed in which a resin is injected onto the mounting surface of the substrate and the electric/electronic component and the circuit or the like are buried in the resin in order to prevent the electric/electronic component mounted on the substrate and the circuit or the like on the mounting surface of the substrate from being soaked in water or contaminated. When potting is performed on a substrate, it is necessary to increase the height of the substrate connector to such an extent that the substrate connector mounted on the mounting surface of the substrate is not buried in resin. Further, the cable connector 1 needs to be separated from the mounting surface of the substrate so that the cable connector connected to the substrate connector at the same time does not come into contact with the resin injected onto the mounting surface of the substrate. According to the present embodiment, as shown in fig. 13, the height of the substrate connector 61 can be increased, and the distance D between the cable connector 1 connected to the substrate connector 61 and the mounting surface 85A of the substrate 85 can be made sufficiently larger than the thickness E of the resin 86 injected onto the mounting surface 85A of the substrate 85. This makes it possible to easily apply the cable connector 1 and the substrate connector 61 to products requiring potting of a substrate.
In the embodiment of the present invention, the positions of the contact portions 63 of the 30 terminals in the vertical direction are the same in the board connector 61, but the positions of the contact portions 26 of the 15 second terminal pieces 21 arranged on the front side are higher than the positions of the contact portions 26 of the 15 second terminal pieces 21 arranged on the rear side in the insertion portion 51 of the cable connector 1. According to this configuration, when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61, first, the contact portions 26 of the 15 second terminal pieces 21 arranged on the rear side in the insertion portion 51 of the cable connector 1 are brought into contact with the contact portions 63 of the 15 terminals 62 arranged on the rear side in the insertion recess 71 of the board connector 61, and then the contact portions 26 of the 15 second terminal pieces 21 arranged on the front side in the insertion portion 51 of the cable connector 1 are brought into contact with the contact portions 63 of the 15 terminals 62 arranged on the front side in the insertion recess 71 of the board connector 61. Thus, for example, the plurality of cables 80 can be connected to the circuit provided on the substrate with a time difference in an appropriate order, as in the case where the ground lines of the 30 cables 80 are connected to the ground lines of the circuit provided on the substrate and then the signal lines of the 30 cables 80 are connected to the signal lines of the circuit provided on the substrate. Therefore, when the cable connector 1 is connected to the board connector 61, it is possible to prevent an electrical failure such as an abnormal current flowing through a circuit or the like provided on the board.
In the embodiment of the present invention, the spacer 73 is provided in the insertion recess 71 of the board connector 61, and the spacer 73 separates the 15 terminals 62 arranged in the front row from the 15 terminals 62 arranged in the rear row. The rear end of each terminal 62 of the board connector 61 is located below the upper edge of each of the partition plate 73, the front plate 67, the rear plate 68, the left plate 69, and the right plate 70. In the housing 31 of the cable connector 1, the groove 54 is provided in the second partition wall 44 provided between the 15 second terminal piece housing portions 42 arranged on the front side and the 15 second terminal piece housing portions 42 arranged on the rear side. The left end 54A and the right end 54B of the groove 54 are closed by the left wall 36 and the right wall 37, respectively. According to this configuration, even when the position of the insertion portion 51 of the cable connector 1 is displaced from the position of the insertion recess 71 of the substrate connector 61 when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the substrate connector 61, it is possible to prevent a part of the insertion portion 51 of the cable connector 1 from colliding with the terminal 62 of the substrate connector 61 from an oblique side, and to prevent the terminal 62 from being bent by an impact of the collision of the part of the insertion portion 51. Specifically, each terminal 62 of the substrate connector 61 protrudes upward from the bottom surface of the insertion recess 71, and the tail end of each terminal 62 is separated from each of the partition plate 73, the front plate portion 67, the rear plate portion 68, the left plate portion 69, and the right plate portion 70, so that the terminal 62 may be bent when the tail end of the terminal 62 is biased from an oblique side. However, in the present embodiment, the insertion portion 51 of the cable connector 1 does not enter the insertion recess 71 of the board connector 61 as long as the insertion portion 51 of the cable connector 1 is not inserted into the insertion recess 71 of the board connector 61 in an accurate direction at an accurate position. For example, when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61 obliquely forward, backward, leftward or rightward with respect to the insertion recess 71, the lower end portion of the left wall portion 36 or the lower end portion of the right wall portion 37 of the housing 31 of the cable connector 1 collides with the upper end portion of the partition plate 73, the upper end portion of the front plate portion 67, the upper end portion of the rear plate portion 68, the upper end portion of the left plate portion 69, or the upper end portion of the right plate portion 70, and the insertion portion 51 of the cable connector 1 cannot enter the insertion recess 71 of the board connector 61. Therefore, a part of the insertion portion 51 of the cable connector 1 can be prevented from colliding with the terminal 62 of the substrate connector 61 from an oblique side, and the terminal 62 can be prevented from being bent. Since the left end 73A and the right end 73B of the partition 73 are separated from the left plate portion 69 and the right plate portion 70, respectively, when the insertion portion 51 of the cable connector 1 is inserted into the insertion recess 71 of the board connector 61 at a correct position and in a correct direction, the lower end portion of the left wall portion 36 and the lower end portion of the right wall portion 37 of the housing 31 of the cable connector 1 enter the gap between the left end 73A of the partition 73 and the left plate portion 69 and the gap between the right end 73B of the partition 73 and the right plate portion 70 in the insertion recess 71 of the board connector 61, respectively. As a result, the insertion portion 51 of the cable connector 1 is accurately inserted into the insertion recess 71 of the substrate connector 61.
In the cable connector 1 according to the embodiment of the present invention, the first terminal pieces 11 of all the terminals 5 included in the cable connector 1 have the same shape. The second terminal pieces 21 of all the terminals 5 included in the cable connector 1 have the same shape. Therefore, the plurality of first terminal pieces 11 can be used for the purpose of the generalization of the components, and the plurality of second terminal pieces 21 can be used for the purpose of the generalization of the components. Therefore, the manufacturing cost of the cable connector 1 can be reduced.
In the above-described embodiment, the cable connector 1 in which the number of the terminals 5, the terminal accommodating portions 40, and the like is 30, and the board connector 61 in which the number of the terminals 62 is 30 are exemplified, but the number of the terminals, the terminal accommodating portions, and the like is not limited in the cable connector of the present invention, and the number of the terminals is not limited in the board connector of the present invention. In the cable connector 1, the number of the terminals 5 and the terminal receiving portions 40 may be 1. In addition, in the cable connector 1 of the above embodiment, the plurality of terminals are arranged in two layers, but the plurality of terminals may be arranged in one layer, or the plurality of terminals may be arranged in three or more layers. The plurality of terminals may be arranged in three or more rows in the substrate connector 61.
In the cable connector according to the present invention, the structure for coupling the first terminal piece and the second terminal piece is not limited to the structure described in the embodiment. In the present invention, the structure in which the second terminal piece of the cable connector is in contact with the terminal of the board connector is not limited to the structure described in the embodiments. Further, the housing of the cable connector according to the present invention may be integrated without all the wall portions being joined so as not to be separable.
The present invention can be modified as appropriate within a range not departing from the spirit or scope of the present invention that can be understood from the claims and the specification as a whole, and a connector for a cable and a connector for a board that are accompanied by such modification are also included in the technical idea of the present invention.
