Description

  The present invention relates to a terminal alignment plate and a mounting component with a terminal alignment plate.

  Conventionally, various mounting parts are mounted on a printed wiring board. An example of the mounted component is an electrical connector that connects a printed wiring board and another circuit.

  FIG. 16 is a cross-sectional view showing an example of a structure in which the electrical connector 200 is mounted on the printed wiring board 300. In FIG. 16, the electrical connector 200 includes a plurality of contacts 210 and 220 that are inserted through and connected to a plurality of insertion holes (through holes) formed in the printed wiring board 300, and the contacts 210 and 220 are arranged. Housing 230. FIG. 16 shows the electrical connectors 200 arranged in two rows. The contacts 210 are arranged in one row on the housing 230 side, and the contacts 220 are arranged in the other side. Each of the contacts 210 and 220 has a leg portion (tine portion) that protrudes outside the housing 230 and penetrates the printed wiring board 300, and a connection portion that connects to the mating connector.

  Here, generally, the leg portions of the contacts 210 and 220 are formed of a soft metal plate and protrude to the outside of the housing 230, and thus may be deformed when the electrical connector 200 is handled. If the legs of the contacts 210 and 220 are deformed, it is difficult to insert the contacts 210 and 220 into the insertion holes when mounting on the printed wiring board 300. In order to prevent such deformation of the contacts 210 and 220, a tine plate (terminal alignment plate) 100 is attached to the contacts 210 and 220 (see, for example, Patent Document 1).

16 and 17, the tine plate 100 is a plate-like insulating member in which a plurality of through holes 110 and 120 through which the legs of the contacts 210 and 220 pass are formed. Then, by handling the electrical connector 200 by passing the legs of the contacts 210 and 220 through the through holes 110 and 120 of the tine plate 100, respectively, the deformation of the legs of the contacts 210 and 220 can be prevented and the contacts 210 and 220 can be prevented. The 220 alignment state is maintained.

  However, in the tine plate disclosed in Patent Document 1, since the electrical connector 200 is mounted on the printed wiring board 300 with the tine plate 100 mounted, the tine plate 100 is mounted even after completion. It becomes. For example, since the contacts 210 and 220 are metal plates and the tine plate 100 is formed of an insulating member, the members having different thermal expansion coefficients are mounted in combination. Therefore, when temperature variation occurs in a state where the printed wiring board 300 and the electrical connector 200 are mounted, stress is applied to the joint between the leg portions of the contacts 210 and 220 and the printed wiring board 300 due to thermal expansion stress. For example, when the leg portions of the contacts 210 and 220 are joined to the printed wiring board 300 by soldering or the like, there is a risk of causing cracks in the solder at the joint portion. In addition, since the electrical connector 200 is mounted on the printed wiring board 300 with the tine plate 100 mounted, it is a factor that increases the weight of the mounted component.

(First embodiment)
The terminal alignment plate according to the first embodiment of the present invention will be described below with reference to FIGS. Typically, the terminal alignment plate is used by being incorporated in a mounting component such as an electrical connector mounted on a printed wiring board, and will be referred to as a tine plate in the following description. FIG. 1 is a perspective view showing an example of the structure of the tine plate 1a and the electrical connector 9. As shown in FIG. FIG. 2 is a front view showing an example of the structure of the tine plate 1 a and the electrical connector 9.

  1 and 2, the electrical connector 9 includes a plurality of contacts 91 and 92 that are respectively inserted and connected to a plurality of insertion holes (through holes) formed in the printed wiring board, and the contacts 91 and 92 are connected to each other. The housings 93 are arranged. 1 and 2 show the electrical connector 9 in which contacts 91 and 92 are arranged in two rows. The contacts 91 are arranged in one row on the housing 93 side, and the contacts 92 are separated from the housing 93. It is lined up on the other side. Each of the contacts 91 and 92 has a leg portion (tine portion) that protrudes outside the housing 93 and penetrates the printed wiring board, and a connection portion that connects to the mating connector. In addition, since the connection part of the contacts 91 and 92 is formed in the housing 93, illustration is abbreviate | omitted, and only the leg part of the contacts 91 and 92 is shown in FIG. 1 and FIG. In addition, the contacts 91 and 92 are arranged in a row, and the arrangement direction of the through holes through which the contacts 91 and 92 are inserted corresponds to an example of the first row direction of the present invention.

  In order to prevent the deformation of the contacts 91 and 92 until the electrical connector 9 is mounted, a tine plate (terminal alignment plate) 1a is attached to the contacts 91 and 92. The tine plate 1a is a plate-like insulating member in which a plurality of terminal holding holes through which the legs of the contacts 91 and 92 pass are formed. For example, the tine plate 1a is made of a resin material such as PBT (polybutylene terephthalate). The terminal holding holes are opened corresponding to the through holes of the printed wiring board through which the legs of the contacts 91 and 92 are respectively inserted. The terminal holding hole communicates with a plurality of cutout holes opened to one end of the plate of the tine plate 1a. The terminal holding hole and the cutout hole are combined to form a slit-shaped opening Na. Is configured. Then, the leg portions of the contacts 91 and 92 are respectively passed through the terminal holding holes of the tine plate 1a to handle the electrical connector 9, thereby preventing the leg portions of the contacts 91 and 92 from being deformed and maintaining the aligned state. .

  Next, the structure of the tine plate 1a and the state in which the tine plate 1a is attached to the contacts 91 and 92 will be described with reference to FIGS. FIG. 3 is a top view showing an example of the shape of the tine plate 1a. FIG. 4 is a detailed view of a portion A of the tine plate 1a shown in FIG. FIG. 5 is a top view showing an example of a state in which the tine plate 1 a is attached to the electrical connector 9.

  In FIG. 3, the slit-shaped opening Na is formed by a slit NMa that opens to one end of the tine plate 1 a and terminal holding holes NBIa and NBOa that communicate with the slit NMa. The slit NMa is a slit whose vertical direction is the longitudinal direction with respect to a side surface (hereinafter referred to as the back side surface) that faces the housing 93 when the tine plate 1a is attached to the electrical connector 9. A plurality of tine plates 1a are formed in a shape. The slits NMa open to the back side surface. Further, terminal holding holes NBIa and NBOa are formed on one side (left side in the example shown in FIG. 3) with respect to the longitudinal direction of the slit NMa so as to communicate with the slit NMa. Specifically, the slit-shaped opening Na is formed in an approximately F shape of the alphabet, the F-shaped vertical image is the slit NMa, the F-shaped upper horizontal image is the terminal holding hole NBOa, and the F-shaped lower horizontal image. Respectively correspond to the terminal holding holes NBIa. The lower end of the F-shaped vertical image in the slit-shaped opening Na is open on the back side surface of the tine plate 1a. A plurality of such slit-shaped openings Na are formed side by side on the tine plate 1a in accordance with the contacts 91 and 92 to be mounted. The direction in which the terminal holding holes NBIa and NBOa are arranged in a row corresponds to an example of the first row direction of the present invention. Further, the direction in which the longitudinal direction of the slit NMa is formed corresponds to an example of the second row direction of the present invention.

  In FIG. 4, a pair of retaining protrusions NPa are formed at portions connecting the slit NMa and the terminal holding holes NBIa and NBOa. The interval between the retaining protrusions NPa is set to be equal to or narrower than the widths of the contacts 91 and 92 to be mounted. As a result, when the leg portions of the contacts 91 and 92 are inserted into the terminal holding holes NBIa and NBOa, respectively, the retaining protrusion NPa can be easily moved from the terminal holding holes NBIa and NBOa to the slit NMa. It can be prevented from slipping out.

  1 to 3 and 5, the tine plate 1a is provided with a first handle portion 11a and a second handle portion 15a, respectively. The first handle portion 11a is erected on the plate surface in the vicinity of one end portion of both end surfaces perpendicular to the back side surface of the tine plate 1a. Specifically, the first handle portion 11a is in the vicinity of the end surface of the tine plate 1a opposite to the direction in which the terminal holding holes NBIa and NBOa are formed with respect to the slit NMa (left side in the example of FIG. 3). In the example of FIG. Further, the second handle portion 15a is erected on a plate surface in the vicinity of a side surface (hereinafter referred to as a front side surface) facing the back side surface of the tine plate 1a.

  The 1st handle part 11a has the positioning part 111a and the finger hook part 112a. The positioning portion 111a is a fitting protrusion formed so as to protrude outward from the plate surface of the tine plate 1a. The positioning portion 111a engages with the concave portion of the housing 93 when the tine plate 1a is attached to the electrical connector 9. As shown in FIG. 2, when the tine plate 1a is attached to the electrical connector 9, the finger hook portion 112a is a member that is exposed and arranged outside.

  As shown in FIG. 5, when the tine plate 1a is attached to the electrical connector 9, the tine plate 1a is inserted in a state in which the pair of contacts 91 and 92 and the pair of terminal holding holes NBIa and NBOa are inserted in alignment with each other. Attach to the electrical connector 9. At this time, since the contacts 91 and 92 are held in the regions surrounded by the terminal holding holes NBIa and NBOa and the retaining protrusion NPa, respectively, the horizontal direction and the front-rear direction of the tine plate 1a are positioned. As shown in FIG. 2, in a state where the tine plate 1a is mounted on the electrical connector 9, the positioning portion 111a and the concave portion of the housing 93 are fitted to position the tine plate 1a in the vertical direction.

  Next, a method for removing the tine plate 1a from the electrical connector 9 will be described with reference to FIGS. FIG. 6 is a top view showing a first stage when the tine plate 1a is detached from the electrical connector 9. FIG. FIG. 7 is a top view showing a second stage in removing the tine plate 1a from the electrical connector 9. FIG.

  In FIG. 5, in a state where the tine plate 1a is attached to the electrical connector 9, the pair of contacts 91 and 92 and the pair of terminal holding holes NBIa and NBOa are inserted in alignment with each other. Therefore, since contacts 91 and 92 are respectively held in the regions surrounded by terminal holding holes NBIa or NBOa and retaining protrusion NPa, contacts 91 and 92 are aligned in accordance with the positions of terminal holding holes NBIa and NBOa. The position of is maintained. In such an aligned state, the contacts 91 and 92 are inserted and joined into the insertion holes of the printed wiring board, and the electrical connector 9 is mounted at a predetermined position on the printed wiring board.

  The tine plate 1a can be detached from the electrical connector 9 after the electrical connector 9 is mounted on the printed wiring board. In FIG. 6, an operator handling the mounted product applies a force in the direction toward the center portion of the tine plate 1 a to the first handle portion 11 a (for example, pressing the first handle portion 11 a in the illustrated force application direction) The entire tine plate 1a slides in this direction (movement in the direction of movement of the illustrated plate). Due to the sliding movement of the tine plate 1a, the contacts 91 and 92 held in the region surrounded by the terminal holding holes NBIa or NBOa and the retaining projections NPa get over between the pair of retaining projections NPa and are on the slit NMa side. Get out to each. That is, the stress required to move the entire tine plate 1a in the plate moving direction is greatly affected by the interval between the pair of retaining projections NPa, and when the tine plate 1a is removed by adjusting the interval. The necessary force and the force with which the tine plate 1a holds the contacts 91 and 92 in alignment can be adjusted. Further, as described above, the finger hook portion 112a of the first handle portion 11a is exposed, and in order to remove the tine plate 1a, an operator puts a finger on the finger hook portion 112a and applies the force to the first handle portion 11a. The work of pushing or pulling in the direction becomes easy.

  In FIG. 7, the operator applies a force in a direction in which the second handle portion 15a is pulled away from the housing 93 in a state where the contacts 91 and 92 are pulled out to the slit NMa side (for example, the second handle portion 15a is illustrated in the direction in which the force is applied). The whole tine plate 1a slides in that direction (moving in the direction of movement of the illustrated plate). Due to the sliding movement of the tine plate 1a, the contacts 91 and 92 move along the slit NMa, and eventually come out of the slit-shaped opening Na. Thus, the tine plate 1a can be detached from the electrical connector 9 after mounting by performing sliding movement in two directions.

  Thus, since the tine plate 1a according to the embodiment can be removed after mounting the components, the mounting operation is performed while maintaining the aligned state of the contacts 91 and 92, and then the contacts 91 and 92 and the print are printed. The stress applied to the connection part with the wiring board can be reduced. For example, even when the temperature fluctuates in a state where the electrical connector 9 is mounted on the printed wiring board, since the tine plate 1a is not attached, stress on the joint due to the above-described thermal expansion stress does not occur. Therefore, even when the leg portions of the contacts 91 and 92 are joined to the printed wiring board by soldering or the like, it is possible to prevent cracks that occur in the solder at the joint portion. Further, since the tine plate 1a is removed after the electrical connector 9 is mounted, the weight of the finished product as a mounted component can be reduced. Further, by using the first handle portion 11 and the second handle portion 15, the tine plate 1a can be easily removed from the terminal holding hole NBIa or NBOa through the slit NMa. Further, the tine plate 1a holds the contacts 91 and 92 in a small region surrounded by the terminal holding hole NBIa or NBOa and the retaining protrusion NPa. Therefore, the position where the contacts 91 and 92 are aligned is compared with a hole shape that is relatively freely movable (for example, a shape without the retaining protrusion NPa or a shape having a relatively larger margin than the cross-sectional shape of the contacts 91 and 92). Since the accuracy is increased, the mounting position accuracy is also increased.

(Second Embodiment)
Hereinafter, with reference to FIG. 8 and FIG. 9, the tine plate 1b which concerns on the 2nd Embodiment of this invention is demonstrated. FIG. 8 is a perspective view showing an example of the structure of the tine plate 1b and the electrical connector 9.

In addition, the said protrusion does not need to prevent the contacts 91 and 92 from actively pulling out like the above-mentioned retaining protrusion NPa. For example, the interval between the protrusions may be set wider than the width of the contacts 91 and 92 to be mounted. As will become apparent from the description below, in the tine plate 1b, the force that moves the terminal holding holes NBIb and NBOb toward the contacts 91 and 92 is always acting by the elastic force of the spring. It becomes unnecessary to hold in the holding holes NBIb and NBOb.

  The holding part 12b has a spring part 121b and a positioning part 122b. Both the spring part 121b and the positioning part 122b are members provided outside the plate surface of the tine plate 1b. For example, the spring portion 121b is formed of a plate-like member bent into a U-shape, and when the tine plate 1b is attached to the electrical connector 9, the tine plate 1b is provided on the end portion side where the first handle portion 11b is provided. (See FIG. 9). The positioning portion 122b fits into the recess of the housing 93 when the tine plate 1b is attached to the electrical connector 9.

  As shown in FIG. 10, when the tine plate 1b is attached to the electrical connector 9, the tine plate 1b is inserted in a state where the pair of contacts 91 and 92 and the pair of terminal holding holes NBIb and NBOb are inserted in alignment with each other. Attach to the electrical connector 9. At this time, the tine plate 1b is urged by the elastic force of the spring portion 121b toward the end portion where the first handle portion 11b is provided. Therefore, contacts 91 and 92 are respectively held toward terminal holding holes NBIb and NBOb, and the tine plate 1b is positioned in the left-right direction and the front-rear direction. As shown in FIG. 9, when the tine plate 1b is attached to the electrical connector 9, the positioning portions 111b and 122b and the concave portion of the housing 93 are fitted to each other so that the vertical direction of the tine plate 1b is positioned. The

  Next, a method for removing the tine plate 1b from the electrical connector 9 will be described with reference to FIGS. FIG. 11 is a top view showing a first stage when the tine plate 1b is removed from the electrical connector 9. FIG.

  In FIG. 10, in a state where the tine plate 1b is attached to the electrical connector 9, the pair of contacts 91 and 92 and the pair of terminal holding holes NBIb and NBOb are inserted in alignment with each other. Since contacts 91 and 92 are held toward terminal holding holes NBIb and NBOb by spring portion 121b, the positions of contacts 91 and 92 are held in an aligned state corresponding to the positions of terminal holding holes NBIb and NBOb. In such an aligned state, the contacts 91 and 92 are inserted and joined into the insertion holes of the printed wiring board, and the electrical connector 9 is mounted at a predetermined position on the printed wiring board.

  Similarly to the tine plate 1a, the tine plate 1b can be detached from the electrical connector 9 after the electrical connector 9 is mounted on the printed wiring board. In FIG. 11, an operator handling the mounted product applies a force to the first handle portion 11b toward the center of the tine plate 1b so as to contract the spring portion 121b (for example, the first handle portion 11b is shown in the drawing force). Press in the direction of application). As a result, the spring portion 121b contracts in the above direction, and the entire tine plate 1b slides in this direction (movement in the illustrated plate movement direction). By the sliding movement of the tine plate 1b, the contacts 91 and 92 held in the terminal holding hole NBIb or NBOb are pulled out to the slit NMb side. That is, the stress necessary to move the entire tine plate 1b in the plate moving direction is greatly influenced by the elastic force of the spring portion 121b. When the tine plate 1b is removed by adjusting the elastic force. The required force and the force with which the tine plate 1b holds the contacts 91 and 92 in alignment can be adjusted. Further, as described above, the finger hook portion 112b of the first handle portion 11b is exposed, and in order to remove the tine plate 1b, the operator puts a finger on the finger hook portion 112b and applies the force to the first handle portion 11b. The work of pushing or pulling in the direction becomes easy.

  After that, in a state where the contacts 91 and 92 are respectively pulled out to the slit NMb side, the operator applies a force in a direction to separate the second handle portion 15b from the housing 93, and the entire tine plate 1b slides in the direction to separate. Since this movement is the same as that in FIG. 7 described above, the illustration is omitted. As the tine plate 1b slides away from the housing 93, the contacts 91 and 92 move along the slit NMb and eventually come out of the slit-like opening Nb. Thus, the tine plate 1b can be detached from the electrical connector 9 after mounting by performing a sliding movement in two directions.

  Thus, since the tine plate 1b according to this embodiment can be removed after component mounting in the same manner as the tine plate 1a, the same effect as that of the tine plate 1a can be obtained.

(Third embodiment)
Hereinafter, with reference to FIG. 12 and FIG. 13, the tine plate 1c which concerns on the 3rd Embodiment of this invention is demonstrated. FIG. 12 is a perspective view showing an example of the structure of the tine plate 1c and the electrical connector 9. FIG. 13 is a front view showing an example of the structure of the tine plate 1 c and the electrical connector 9.

  12 and 13, the tine plate 1c is a plate-like insulating member in which a plurality of terminal holding holes through which the legs of the contacts 91 and 92 pass are formed in the same manner as the tine plates 1a and 1b described above. For example, the tine plate 1c is made of a resin material such as PCT. The terminal holding holes are opened corresponding to the through holes of the printed wiring board through which the legs of the contacts 91 and 92 are respectively inserted. The terminal holding hole communicates with a plurality of cutout holes opened to one end of the plate of the tine plate 1c, and the slit-like opening NcL is formed by combining the terminal holding holes and the cutout holes. And NcR.

  Next, the structure of the tine plate 1c and the state in which the tine plate 1c is attached to the contacts 91 and 92 will be described with reference to FIGS. 14 is a top view showing an example of a state in which the tine plate 1c is attached to the electrical connector 9. As shown in FIG.

  12 to 14, the tine plate 1c is provided with a left first handle portion 11cL, a right first handle portion 11cR, a spring portion 121cI, and a spring portion 121cO. Note that the first handle portion 11cR on the right side is the same as the first handle portion 11a and the second handle portion 15a described above, and thus detailed description thereof is omitted. The left first handle portion 11cL is the same as the right first handle portion 11cR except that the left first handle portion 11cL is provided on the tine plate 1c symmetrically opposite to the right first handle portion 11cR. The detailed explanation is omitted.

  The spring parts 121cI and 121cO are provided on the plate surface of the tine plate 1c. Specifically, the spring portions 121cI and 121cO are provided on plate surfaces that are the center with respect to both end surfaces of the tine plate 1c on which the left first handle portion 11cL and the right first handle portion 11cR are respectively provided.

  The spring parts 121cI and 121cO are formed of U-shaped plate-like members bent upward or downward, and when the tine plate 1c is attached to the electrical connector 9, the tine plate 1c is the left first handle part 11cL. And it urges | biases to the direction which each spreads to the 1st handle part 11cR of the right side (refer FIG. 13). The positioning portion 111cL of the left first handle portion 11cL and the positioning portion 111cR of the right first handle portion 11cR are fitted into the recesses of the housing 93 when the tine plate 1c is attached to the electrical connector 9, respectively.

  The slit-shaped opening NcL is formed by a slit NMcL that opens to one end surface of the tine plate 1c, and terminal holding holes NCIcL and NCOcL that communicate with the slit NMcL. Further, the slit-shaped opening NcR is formed by a slit NMcR that opens to the one end face of the tine plate 1c, and terminal holding holes NCIcR and NCOcR that communicate with the slit NMcR. The slit-shaped opening NcL and the slit-shaped opening NcR are formed in a line-symmetric shape with a predetermined straight line as the center. The slit-shaped opening NcL is formed on the plate surface on the left side of the tine plate 1c where the spring portions 121cI and 121cO are provided. The slit-shaped opening NcR is formed on the plate surface on the right side of the tine plate 1c where the spring portions 121cI and 121cO are provided.

  When the tine plate 1c is mounted on the electrical connector 9, the slit NMcL is formed in the slit 93 so that the longitudinal direction is the longitudinal direction with respect to the back side facing the housing 93 and facing the housing 93. It is formed on the left plate surface. The slits NMcL are each opened to the back side surface. In addition, terminal holding holes NBIcL and NBOcL are formed in communication with the slit NMcL on one side (right side in the example shown in FIG. 14) with respect to the longitudinal direction of the slit NMcL. Specifically, the slit-shaped opening NcL is formed in a shape in which an approximately F letter of the alphabet is turned upside down, the vertical image of the back F shape is the slit NMcL, the upper horizontal image of the back F shape is the terminal holding hole NBOcL, and the back The lower horizontal image of the letter F corresponds to the terminal holding hole NBIcL. The lower end of the vertical F-shaped vertical image at the slit-like opening Nc opens to the back side surface of the tine plate 1c.

  Further, when the tine plate 1c is attached to the electrical connector 9, the slit NMcR is formed on the right side plate surface of the plurality of tine plates 1c in a slit shape with the vertical direction to the longitudinal side as the longitudinal direction. The slits NMcR are also opened to the back side surface. Further, terminal holding holes NBIcR and NBOcR are formed in communication with the slit NMcR on the other side (left side in the example shown in FIG. 14) with respect to the longitudinal direction of the slit NMcR. Specifically, the slit-shaped opening NcR is formed in an approximately F-shape of the alphabet, the F-shaped vertical image is the slit NMcR, the F-shaped upper horizontal image is the terminal holding hole NBOcR, and the F-shaped lower horizontal image. Respectively correspond to the terminal holding holes NBIcR. The lower end of the F-shaped vertical image at the slit-shaped opening Nc is open to the back side surface of the tine plate 1c. A plurality of such slit-like openings NcL and NcR are formed side by side on the tine plate 1c in accordance with the contacts 91 and 92 to be mounted. The direction in which terminal holding holes NBIcL and NBIcR and NBOcL and NBOcR are arranged in a row corresponds to an example of the first row direction of the present invention. The direction in which the longitudinal directions of the slits NMcL and NMcR are formed corresponds to an example of the second row direction of the present invention.

  A pair of protrusions are formed at portions connecting the slit NMc and the terminal holding holes NCIc and NCOc, respectively. In addition, the protrusions may not prevent the contacts 91 and 92 from being actively pulled out like the retaining protrusion NPa described above. For example, the interval between the protrusions may be set wider than the width of the contacts 91 and 92 to be mounted. As will be apparent from the description below, in the tine plate 1c, the force that moves the terminal holding holes NCIcL and NCOcL and the terminal holding holes NCIcR and NCOcR to the contacts 91 and 92 side by the elastic force of the spring is always acting. It becomes unnecessary to hold the contacts 91 and 92 in the terminal holding holes NCIc and NCOc and in the terminal holding holes NCIcR and NCOcR by the retaining protrusion NPa.

  As shown in FIG. 14, when the tine plate 1c is attached to the electrical connector 9, the pair of contacts 91 and 92 and the pair of terminal holding holes NCIcL and NCOcL are inserted in alignment with each other on the left side plate surface of the tine plate 1c. In this state, the tine plate 1c is attached to the electrical connector 9. Further, the tine plate 1c is mounted on the electrical connector 9 with the pair of contacts 91 and 92 and the pair of terminal holding holes NCIcR and NCOcR inserted in alignment with each other on the right side plate surface of the tine plate 1c. At this time, due to the elastic force of the spring parts 121cI and 121cO, the tine plate 1c extends in the direction of spreading from the spring parts 121cI and 121cO to both ends of the left first handle part 11cL and the right first handle part 11cR. Is energized. Therefore, contacts 91 and 92 are held on the terminal holding holes NCIcL and NCOcL side or the terminal holding holes NCIcR and NCOcR side, respectively, and the tine plate 1c is positioned in the left-right direction and the front-rear direction. As shown in FIG. 13, when the tine plate 1c is attached to the electrical connector 9, the positioning portions 111cL and 111cR and the concave portion of the housing 93 are fitted to each other so that the vertical direction of the tine plate 1c is positioned. The

  Next, a method for removing the tine plate 1c from the electrical connector 9 will be described with reference to FIGS. FIG. 15 is a top view showing a first stage when the tine plate 1 c is removed from the electrical connector 9.

  In FIG. 14, when the tine plate 1c is mounted on the electrical connector 9, the pair of contacts 91 and 92 and the pair of terminal holding holes NCIcL and NCOcL, or the pair of contacts 91 and 92 and the pair of terminal holding holes NCIcR and NCOcR is inserted correspondingly. Since the contacts 91 and 92 are held by the spring portions 121cI and 121cO toward the terminal holding holes NCIcL and NCOcL, or the terminal holding holes NCIcR and NCOcR, the contacts 91 and 92 are positioned at the terminal holding holes NCIcL, NCOcL, NCIcR, and NCOcR. The positions of the contacts 91 and 92 are maintained in the corresponding alignment state. In such an aligned state, the contacts 91 and 92 are inserted and joined into the insertion holes of the printed wiring board, and the electrical connector 9 is mounted at a predetermined position on the printed wiring board.

  The tine plate 1c can be detached from the electrical connector 9 after the electrical connector 9 is mounted on the printed wiring board, like the tine plates 1a and 1b. In FIG. 15, the operator who handles the mounted product applies force to the left first handle portion 11cL and the right first handle portion 11cR toward the center portion of the tine plate 1c so as to contract the spring portions 121cI and 121cO. (For example, the left first handle portion 11cL and the right first handle portion 11cR are pulled in the illustrated force application direction). As a result, the spring portions 121cI and 121cO are contracted, and the tine plate 1c is slid and moved so as to be compressed from the left and right (moving in the illustrated plate movement direction). By the sliding movement of the tine plate 1c, the contacts 91 or 92 held in the terminal holding holes NCIcL or NCOcL are pulled out toward the slit NMcL, respectively. Further, the sliding movement of the tine plate 1c causes the contacts 91 or 92 held in the terminal holding holes NCIcR or NCOcR to come out toward the slit NMcR, respectively. That is, the stress necessary to move the entire tine plate 1c in the plate moving direction is greatly influenced by the elastic force of the spring portions 121cI and 121cO, and the tine plate 1c is removed by adjusting the elastic force. At this time, it is possible to adjust the force necessary to align and hold the contacts 91 and 92 by the tine plate 1c. Further, as described above, the finger grip portions 112cL and 112cR of the left first handle portion 11cL and the right first handle portion 11cR are exposed, and the operator can remove the tine plate 1c by using the finger grip portions 112cL and 112cR. The operation of pulling the left first handle portion 11cL and the right first handle portion 11cR toward the force application direction with the finger placed on the finger is facilitated.

  Thereafter, the operator moves the left first handle portion 11cL and the right first handle portion 11cR in a state of pulling them away from the housing 93 in a state where the contacts 91 and 92 are respectively pulled out to the slit NMc side. The entire tine plate 1c slides in the direction of pulling away. Since this movement is the same as that in FIG. 7 described above, the illustration is omitted. By the sliding movement of the tine plate 1c, the contacts 91 and 92 move along the slit NMcL or NMcR, respectively, and eventually come out of the slit-like opening NcL or NcR. Thus, the tine plate 1c can be detached from the electrical connector 9 after mounting by performing a sliding movement in two directions.

  Thus, since the tine plate 1c according to the embodiment can be removed after mounting the components in the same manner as the tine plate 1a, the same effect as that of the tine plate 1a can be obtained.

  In the description of the first to third embodiments described above, the tine plates 1a to 1c are plate-like insulating members made of a resin material such as PBT. However, the tine plates 1a to 1c are made of other materials. It may be configured with. For example, the tine plates 1a to 1c may be made of a plate-like conductor member such as metal. As described above, any of the tine plates 1a to 1c can be removed after mounting, and there is no need to consider conduction between contacts thereafter. As described above, by configuring the tine plates 1a to 1c with metal or the like, the durability of the tine plates 1a to 1c themselves is improved and can be used for a long time. In addition, when the contact legs are joined to the printed wiring board by soldering or the like, the tine plate attached to the contact may also be exposed to a high temperature state, and the joining conditions considering the heat resistance of the tine plate are required. It is necessary to satisfy. However, by using a tine plate with excellent heat resistance such as metal, it is possible to set the joining conditions without considering the heat resistance of the tine plate, and it is possible to expand the variation of the joining process used in the mounting work. it can.

  In the above description of the first to third embodiments, an example in which the material of the tine plates 1a to 1c is integrally formed with a plate-like insulating member made of a resin material such as PBT has been shown. A part of 1a to 1c may be made of other materials. For example, the handle portion (first handle portion 11a, 11b, second handle portion 15a, 15b, left first handle portion 11cL, right first handle portion 11cR), holding portion (12b), and spring portion (121b, 121cI, 121cO) and the like may be made of materials suitable for these functions.

  In the description of the first to third embodiments described above, the handle portion is erected on the plate surface of the tine plate. However, the handle portion may be provided according to other modes. For example, the handle portion may be provided on the end surface of the tine plate in a shape protruding above and below the plate surface. In this case, the handle portion is provided in a T shape with respect to the tine plate.

  Further, in the tine plates 1b and 1c in the second and third embodiments, projections that are set wider than the widths of the contacts 91 and 92 are formed at the portions connecting the slit NMb and the terminal holding holes NBIb and NBOb, respectively. By doing so, it can be expected that the positional accuracy in which the contacts 91 and 92 are aligned and held is improved. However, when such an effect is not expected, the protrusion may not be formed. Even when the protrusions are not formed, since the force for moving the terminal holding hole toward the contact always acts, the contacts can be aligned and held with high positional accuracy. In addition, it is possible to positively prevent the contacts 91 and 92 from coming out by setting the spacing of the projections to be narrow like the retaining projection NPa. In this case, it is conceivable that the force required for removing the tine plate increases. However, it is only necessary to make an appropriate setting for removing the plate by adjusting the elastic force of the spring portion and the protrusion interval.

  In addition, the shape of the tine plate described above, the shape, the number, the installation position, and the like of the grip portion, the holding portion, the spring portion, and the slit-like opening provided on them are merely examples, and other shapes and numbers Needless to say, the present invention can be realized even at the installation position.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.

  The terminal alignment plate and the mounting component with the terminal alignment plate according to the present invention can reduce the stress applied to the connection portion between the contact and the printed wiring board while maintaining the aligned state of the contacts. The present invention can be applied to a terminal alignment plate that is mounted on a terminal of a component mounted on this component, a component before mounting that is transported in a state where the terminal alignment plate is mounted, and the like.
