Description

[Technical field]

[0001] The present invention relates to a connector jig used when inserting and extracting a connector pin crimped to the end of a cable into and from an insertion port of a flat connector. [Background technology]

[0002] For example, a female flat connector is known as a means for electrically connecting various electronic devices to each other. In the female flat connector, a connector pin crimped to the end of a cable is inserted into an insertion port to fix the connector. In this case, the connector pin has an engagement claw formed by cutting outward to prevent it from coming off. When the connector pin is inserted into the insertion port of the female flat connector, the engagement claw of the connector pin engages with the engagement hole of the female flat connector, preventing the cable from coming off the female flat connector.

[0003] Incidentally, the task of inserting and fixing cables into the multiple insertion ports of a female flat connector is usually performed manually by an operator, who inserts and fixes the cables into the insertion ports while visually referring to a comparison table showing the connection relationship between the insertion ports and the cables. In this case, since there are many insertion ports (e.g., about 40 to 60), there is a possibility that the operator will mistakenly insert the cable into an insertion port that should not be inserted.

[0004] To solve the above problems, flat connectors are commercially available that have identification marks such as numbers or symbols near the insertion ports to identify the insertion ports that correspond to each cable, but not all commercially available flat connectors have identification marks.

[0005] Therefore, Patent Document 1 proposes a connector jig that has an identification mark such as a number or symbol to identify the correct insertion port that corresponds to the cable to be inserted.This connector jig makes it possible to prevent cables from being inserted in the wrong place even if the flat connector does not have an identification mark.

[0006] However, when changing a connecting part that connects a cable to a flat connector, the connector pins inserted into the flat connector may be pulled out from the flat connector.

[0007] Therefore, Patent Document 2 proposes a pin removal tool that can easily remove a cable by pressing in an engaging claw of a connector pin. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent Publication No. 2022-083505 [Patent Document 2] JP 2018-006198 A Summary of the Invention [Problem to be solved by the invention]

[0009] However, in order to easily remove the cable while preventing the cable from being mistakenly inserted into the correct insertion port of the flat connector, it is necessary to use both the connector jig proposed in Patent Document 1 and the pin removal jig proposed in Patent Document 2, which results in poor work efficiency.

[0010] The present invention has been made in consideration of the above problems, and its object is to provide a connector jig which prevents a cable from being inserted incorrectly into a flat connector and enables an incorrectly inserted cable to be easily and quickly removed from the flat connector with good workability. [Means for solving the problem]

[0011] In order to achieve the above-mentioned object, the present invention provides a connector jig used when inserting or removing a connector pin fixed to an end of a cable into or from an insertion port of a flat connector having a plurality of insertion ports and engagement holes arranged in parallel, the connector jig comprising: a base having a connector accommodating portion for accommodating the flat connector; a guide rail formed on the base along the arrangement direction of the insertion ports of the flat connector accommodated in the connector accommodating portion; a claw action portion movable along the guide rail and acting on an engagement claw of the connector pin inserted into the insertion port to release the engagement of the engagement claw with the engagement hole; a fixing portion for fixing the claw action portion which moves along the guide rail to a position corresponding to the insertion port; and an identification mark affixed to the position corresponding to the insertion port of the base. Effect of the Invention

[0012] According to the present invention, the connector jig allows the user to correctly insert the cable into the insertion port of the flat connector while referring to the identification mark on the base, so that it is possible to reliably prevent the cable from being inserted incorrectly and to always correctly insert and fix the cable into the insertion port of the flat connector. In addition, in the unlikely event that the cable is inserted incorrectly or when replacing a connecting part connected to the cable, the claw action part provided on the connector jig acts on the engaging claw of the connector pin to release the engagement of the engaging claw with the engaging hole, so that the cable can be easily pulled out. In this case, the cable to be pulled out can be easily identified by the identification mark, and the claw action part can be moved to the position of the cable and fixed by the fixing part, so that the cable pulling operation can be performed quickly and with good workability in a short time.

[0013] Therefore, the single connector jig can prevent the cable from being inserted into the flat connector in the wrong way and can easily and quickly pull out the cable that has been inserted into the flat connector with good workability. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0016] The male terminal-shaped flat connector (hereinafter referred to as the "male connector") 40 and the female terminal-shaped flat connector (hereinafter referred to as the "female connector") 50 shown in FIG. 1 are integrally molded into a flat rectangular plate shape from insulating resin.

[0017] Here, inside a rectangular mounting opening 41a opening on the front surface (the surface on the near side in FIG. 1) of a flat housing 41 of the male connector 40, a plurality of horizontal metallic pins 42 arranged in parallel along the width direction are accommodated in two upper and lower stages, and a pair of engaging claw-like flexible hooks 43 are integrally formed on both the left and right sides of the mounting opening 41a of the housing 41. A rectangular notch 44 is formed in the center of the upper wall of the housing 41 in the left-right direction to guide the mounting of the female connector 50 to the mounting opening 41a. A cable 45 is crimped to each pin 42 and extends from the rear surface (the surface on the far side in FIG. 1) of the housing 41, which is opposite to the front surface where the mounting opening 41a opens.

[0018] On the other hand, a flat housing 51 of the female connector 50 has a front surface (the surface at the back in FIG. 1) facing the male connector 40, on which a plurality of pin holes (not shown) arranged in the width direction are formed in two upper and lower stages, and a rear surface (the surface at the front in FIG. 1) of the housing 51 has a plurality of rectangular insertion openings 52 in two upper and lower stages connected to each pin hole, opening along the width direction. Here, a metal connector pin 54 (see FIG. 2) crimped to an end of a cable 53 is inserted into the housing 51 from each insertion opening 52, and inside the housing 51, as shown in FIG. 8 and FIG. 9, pin accommodating sections 55 for accommodating the connector pins 54 inserted from the insertion openings 52 are formed in the same number as the insertion openings 52. A plurality of rectangular engagement holes 56 (only the upper side is shown in FIG. 2) communicating with each pin accommodating section 55 are opened in a horizontal row on both the upper and lower surfaces of the housing 51.

[0019] A rectangular block-shaped protrusion 57 for positioning is provided at the center of the width of the upper surface of the housing 51 of the female connector 50, and engaging recesses 51a are formed on both the left and right side surfaces of the housing 51.

[0020] In the male connector 40 and female connector 50 configured as above, the mounting port 41a opening on the front side (near side in FIG. 1) of the male connector 40 is fitted into the front side (rear side in FIG. 1) of the female connector 50, and the hooks 43 formed on both the left and right sides of the male connector 40 are engaged with the engaging recesses 51a formed on both the left and right sides of the female connector 50, thereby connecting the male connector 40 and the female connector 50 to each other. At this time, the convex portion 57 protruding from the top surface of the housing 51 of the female connector 50 fits into the notch 44 formed in the top wall of the housing 41 of the male connector 40, so that the male connector 40 and the female connector 50 are correctly connected while being positioned in the left-right direction (width direction).

[0021] Thus, when the male connector 40 and the female connector 50 are connected as described above, each of the multiple pins 42 of the male connector 40 is inserted into each of the multiple pin holes (not shown) of the female connector 50, and when each pin 42 comes into contact with each of the connector pins 54 accommodated in each of the pin accommodating portions 55 (see Figures 8 and 9) of the female connector 50, each of the multiple cables 45 connected to the male connector 40 and each of the multiple cables 53 connected to the female connector 50 are electrically connected to each other, and electronic devices (not shown) are electrically connected to each other via these cables 45, 53.

[0022] Here, the configuration and crimping method of connector pins 54 crimped to the ends of cables 53 inserted from the insertion ports 52 of female connector 50 will be described below with reference to FIG.

[0023] As shown in Fig. 2(a), the connector pin 54 is formed by bending a conductive metal plate, with a socket section 54A formed at one end and a cable crimping section 54B formed at the other end. Here, the socket section 54A is a section that receives the pin 42 of the male connector 40 (see Fig. 1), and is formed in a rectangular tube shape with a top wall, a bottom wall and both side walls, and an engagement claw 54a for preventing the pin from coming off is formed by cutting and raising a part of the top wall. Although not shown, a contact spring (not shown) is formed inside the socket section 54A by folding back a part of the top wall and the bottom wall to the inside of the socket section 54A, and when this contact spring comes into contact with the pin 42 of the male connector 40 (see Fig. 1), they are electrically connected to each other.

[0024] 2(a), the cable crimping portion 54B is provided with a U-shaped cross-section outer sheath crimping portion 54b that holds the outer sheath 53a of the cable 53, and a U-shaped cross-section core crimping portion 54c that holds the bundle of core wires 53b exposed from the outer sheath 53a of the cable 53. As shown in FIG. 2(b), the outer sheath crimping portion 54b is bent inwardly and crimped to the outer sheath 53a of the cable 53, and the core wire crimping portion 54c is bent inwardly and crimped to the bundle of core wires 53b, thereby electrically connecting the cable 53 and the connector pin 54 via the cable crimping portion 54B.

[0025] When the connector pin 54 configured as described above is inserted into the insertion port 52 of the female connector 50 shown in FIG. 1, the engaging claws 54a engage with the engaging holes 56 of the female connector 50, thereby fixing the connector pin 54 in place; details of this will be described later.

[0026] Next, the configuration and operation of the connector jig 1 according to the present invention will be described below with reference to Figures 3 to 10. In the following description, the arrow directions in Figures 3 and 7 are defined as "left and right", "front and back", and "up and down" directions, respectively, as shown in the figures.

[0027] [Configuration of connector jig] The connector jig 1 according to the present invention is used when inserting and removing a connector pin 54 (see FIG. 2) crimped to an end of a cable 53 into and from an insertion port 52 (see FIG. 1) of a female connector 50, and includes as main components a base 10 for accommodating the female connector 50, upper and lower guide rails 13, 14 (see FIG. 4) formed on the base 10, a pair of left and right claw action parts 20 that can move independently along the guide rails 13, 14, a fixing part 30 (see FIGS. 7 and 10) for fixing the claw action parts 20 that move along the guide rails 13, 14 at predetermined positions, and identification marks M1, M2 (see FIG. 3) attached to the base 10. The main components of the connector jig 1, namely the base 10, the guide rails 13, 14, the claw action parts 20, the fixing part 30, and the identification marks M1, M2, will be described below.

[0028] (Base) The base 10 is a rectangular block-shaped member that is long in the front-rear direction and is integrally molded from insulating resin, and in the center in the left-right direction (width direction), as shown in Figures 3, 4, 7, and 9, a rectangular groove-shaped connector accommodating section 11 is formed along the front-rear direction for accommodating a female connector 50 by inserting it from the direction of the arrow in Figure 7. This connector accommodating section 11 is open at the top and front, and is closed at the rear by a wall 10a (see Figures 3 and 7). Also, as shown in Figures 4, 7, and 9, a recessed groove 11a is formed linearly along the front-rear direction at the left bottom of the connector accommodating section 11 of the base 10 for avoiding interference with the protrusion 57 of the female connector 50 when the female connector 50 is inserted into the connector accommodating section 11 from the direction of the arrow in Figure 7.

[0029] In addition, as shown in Figures 7 and 10, a rectangular opening 10A (only one of which is shown in Figures 7 and 10) that is elongated in the front-to-rear direction is formed on each of the left and right side surfaces of the base 10, and a slit-shaped elongated rectangular insertion hole (only one of which is shown in Figure 10) 12 is formed in a straight line along the front-to-rear direction in the middle of the vertical direction of each opening 10A, as shown in Figures 4 and 10.

[0030] (Guide rail) As shown in Fig. 4, the guide rails 13, 14 are upper and lower convex parts formed in the front-rear direction (perpendicular to the paper surface of Fig. 4) above and below an opening 10A that opens on both the left and right side surfaces of the base 10, and rectangular fitting grooves 15, 16 are formed in the inside of each guide rail 13, 14 of the base 10 in the front-rear direction (perpendicular to the paper surface of Fig. 4). These guide rails 13, 14 guide the movement of the claw action part 20 in the front-rear direction.

[0031] (Claw action part) As shown in Figure 9, the claw action portion 20 acts on the engaging claws 54a of the connector pins 54 inserted through each insertion port 52 of the female connector 50 accommodated in the connector accommodating portion 11 of the connector jig 1 and accommodated in the pin accommodating portion 55, and, when necessary, presses the engaging claws 54a engaged with the engaging holes 56 of the female connector 50 to release the engagement of the engaging claws 54a with the engaging holes 56, and has a rectangular block-shaped housing 21 integrally molded from insulating resin.

[0032] Here, each claw action portion 20 can move independently in the front-to-rear direction (perpendicular to the paper surface of FIG. 4) along guide rails 13, 14 (see FIG. 4) on both the left and right sides of the base 10, and rectangular mating grooves 22, 23 are formed on the upper and lower surfaces of the housing 21 along the front-to-rear direction (perpendicular to the paper surface of FIG. 5(d) and FIG. 6), as shown in FIG. 5(d) and FIG. 6, and flange-shaped mating protrusions 24, 25 are formed on the inside of each mating groove 22, 23 on the upper and lower surfaces of the housing 21 along the front-to-rear direction (perpendicular to the paper surface of FIG. 5(d) and FIG. 6), respectively.

[0033] As shown in FIG. 4, each of the pair of left and right claw action portions 20 is supported on the base 10 so as to be independently movable in the front-to-rear direction (perpendicular to the paper surface of FIG. 4) by fitting protrusions 24, 25 formed on the inner ends of the upper and lower surfaces of the housing 21 into upper and lower fitting grooves 15, 16 formed in the base 10, and by fitting grooves 22, 23 formed on the upper and lower surfaces of the housing 21 into upper and lower guide rails 13, 14 of the base 10.

[0034] 5(b), a cylindrical spring accommodating portion S1 is formed in the inner center of the housing 21 of each claw action portion 20, and large and small rectangular holes 21a, 21b are formed on both the left and right sides of the spring accommodating portion S1 in the center of the housing 21, as shown in Fig. 4. A square column-shaped pressing portion 26 is fitted into one rectangular hole 21a of each housing 21 so as to be slidable in the left-right direction, and a square column-shaped claw pressing portion 27 extending horizontally integrally from the center of the pressing portion 26 is inserted into the other rectangular hole 21b.

[0035] Here, as shown in Fig. 4, a disk-shaped flange portion 28 housed in a spring housing portion S1 is integrally formed between the pressing portion 26 and the claw pressing portion 27, and this flange portion 28 is biased outward (to the right in Fig. 6) by a coil spring 29 as a biasing portion compressed in the spring housing portion S1. Therefore, in the state shown in Figs. 6 and 9(a) where the pressing portion 26 is not pressed, the flange portion 28 abuts against the inner wall of the spring housing portion S1. In this state, as shown in Fig. 9(a), in the left and right claw action portions 20, a part (end portion) of each pressing portion 26 protrudes outward from the end face of the housing 21, and the claw pressing portion 27 is housed inside the insertion hole 12 formed in the base 10. In this state, the claw holding portion 27 does not act on the engaging claw 54a of the connector pin 54 accommodated in the pin accommodating portion 55 of the female connector 50 accommodated in the base 10, and the engaging claw 54a remains engaged with the engaging hole 56, thereby preventing the connector pin 54 and the cable 53 from coming loose.

[0036] (fixed part) The fixing portion 30 shown in Figures 7 and 10 is intended to fix the left and right claw action portions 20, which can each move independently in the fore-and-aft direction relative to the base 10, to predetermined positions (specifically, positions corresponding to specific ones of the multiple insertion openings 52 opening in the female connector 50), and to impart a clicking sensation (a feeling of moderation) to the movement of each claw action portion 20 in the fore-and-aft direction.

[0037] As shown in Figures 7 and 10, this fixing portion 30 is composed of a leaf spring 31 (see Figure 10) that selectively engages with multiple sawtooth-shaped recesses (valleys) 14a and protrusions (ridges) formed on a pair of guide rails 14 (only one of which is shown in Figures 7 and 10) formed on the lower left and right sides of the base 10.

[0038] Here, as shown in Fig. 7 and Fig. 10, the recessed portion 14a and the protruding portion 14b are alternately formed along the front and rear of each of the left and right guide rails 14 formed on the lower side of the base 10, and the leaf springs 31 are accommodated inside the housings 21 of the left and right claw action parts 20, as shown in Fig. 5(b). Here, as shown in Fig. 5(b) and Fig. 10, a spring accommodating portion S2 long in the front-rear direction is formed in the lower part of the housing 21 of each claw action part 20, and an opening 32 opens toward the lower fitting groove 23 at the center in the front-rear direction of this spring accommodating portion S2. A sheet metal leaf spring 31 is accommodated in the spring accommodating portion S2 of the housing 21, and a V-shaped engagement portion 31a formed in the center of this leaf spring 31 protrudes into the fitting groove 23 from the opening 32.

[0039] When the V-shaped engagement portion 31a of the leaf spring 31 accommodated in the spring accommodating portion S2 of the housing 21 of each of the left and right claw action portions 20 selectively engages with the recessed portion 14a formed in the guide rail 14 on the lower side of the base 10 as shown in Fig. 10(a), the movement of the claw action portion 20 is prevented and the claw action portion 20 is fixed in a predetermined position. When a force is applied to the claw action portion 20 in the fixed state as shown in Fig. 10(a) in the direction of the arrow in Fig. 9(b), for example, the engagement portion 31a of the leaf spring 31 provided in the claw action portion 20 overcomes the convex portion 14b formed in the guide rail 14 on the lower side of the base 10 one after another as shown in Fig. 10(b), so that the claw action portion 20 can move in the direction of the arrow in Fig. 10(b).

[0040] Here, when the claw action part 20 moves, the claw pressing part 27 provided on the claw action part 20 slides inside the insertion hole 12. Note that while Figures 10(a) and (b) respectively show the fixed state and the moving state of one of the claw action parts 20, the other claw action part 20 is similarly fixed at a predetermined position and can move in the front-rear direction from the fixed position.

[0041] (Identification mark) The identification marks M1, M2 are marks attached to the connector jig 1 to prevent the cable 53 from being inserted incorrectly into the multiple insertion ports 52 of the female connector 50, and, in the unlikely event that the cable 53 is inserted incorrectly, to quickly identify the incorrectly inserted cable 53 and to disengage the connector pins 54 of the cable 53 so that the cable 53 can be easily pulled out. In this embodiment, the identification marks M1, M2 are composed of numbers "1" to "50" attached along the front-rear direction on both the left and right sides of the connector housing portion 11 on the top surface of the base 10 of the connector jig 1, as shown in Fig. 3.

[0042] Specifically, 25 identification marks M1 and M2 are formed in a row along the front-rear direction on the base 10 of the connector jig 1, and as shown in FIG. 3, 25 odd numbers "1" to "49" are marked in a row at equal intervals in the front-rear direction on the left side of the connector accommodating portion 11 on the upper surface of the base 10 as identification marks M1, and 25 even numbers "2" to "50" are marked in a row at equal intervals in the front-rear direction on the right side as identification marks M2. Also, as shown in FIG. 5(a) and FIG. 7, an arrow (triangle mark) M is marked on the upper surface of the housing 21 of each of the left and right claw action parts 20 to indicate where the claw action part 20 is located according to the number marked on the base 10. The 50 cables 53 to be inserted into each insertion port 52 of the female connector 50 are also marked with numbers "1" to "50" corresponding to the numbers marked on the base 10 of the connector jig 1.

[0043] In the present embodiment, the numbers "1" to "50" are used as the identification marks M1 and M2, but the identification marks M1 and M2 may be any other characters, figures, patterns, colors, or combinations thereof other than numbers. Also, the number of identification marks M1 and M2 is not limited to 50 and is arbitrary.

[0044] [Function of connector jig] Next, the operation (method of use) of the connector jig 1 configured as above will be described.

[0045] When using the connector jig 1, as shown in Fig. 7, the female connector 50 is inserted in the direction of the arrow from the opening of the connector accommodating section 11 formed on the base 10 of the connector jig 1. In this case, the convex portion 57 protruding from the female connector 50 is aligned with the concave groove 11a formed in the lower part of the connector accommodating section 11 of the connector jig 1. Then, from this state, the female connector 50 is inserted into the connector accommodating section 11 of the connector jig 1 in the direction of the arrow in Fig. 7, and when the tip (the tip in the insertion direction) of the female connector 50 abuts against the wall 10a covering one end of the connector accommodating section 11 of the connector jig 1, the female connector 50 is securely attached to the connector jig 1. At this time, the convex portion 57 protruding from the female connector 50 slides in the left-right direction within the concave groove 11a formed in the connector accommodating section 11 of the connector jig 1, so that the female connector 50 is smoothly attached to the connector jig 1.

[0046] When the female connector 50 is inserted and attached into the connector receiving portion 11 of the connector jig 1 as shown in Fig. 9 as described above, the cables 53 are inserted into and fixed in the insertion openings 52 of the female connector 50, and at this time, each cable 53 is inserted into the insertion opening 52 having the same number as the cable 53. Here, the procedure for inserting and fixing one cable 53 into the female connector 50 will be described below with reference to Fig. 8.

[0047] That is, as shown in Fig. 8(a), a cable 53, which is numbered the same as the number assigned to the insertion port 52, is inserted into an insertion port 52 of a female connector 50 in the direction of the arrow (downward) in the drawing, with a connector pin 54 crimped to its end leading. Then, an engagement claw 54a standing on the connector pin 54 abuts against the periphery of the insertion port 52 of the female connector 50, and the engagement claw 54a is folded and buried inside the connector pin 54 as shown by the dashed line in Fig. 8(b). Therefore, the cable 53 can be inserted as it is, and the connector pin 54 can be fitted into the pin housing portion 55 of the female connector 50.

[0048] Then, when the engaging claws 54a of the connector pins 54 reach the engaging holes 56 formed in the housing 51 of the female connector 50, the engaging claws 54a rise in the direction of the arrow as shown in Fig. 8(c) due to their own elastic restoring force and engage with the engaging holes 56, so that the connector pins 54 are fixed together with the cables 53 and the cables 53 are reliably prevented from coming off. In this way, as shown in Fig. 9(a), when the cables 53 are inserted into the insertion openings 52 of the female connector 50 and the connector pins 54 crimped to the ends of the cables 53 are received in the pin receiving sections 55 of the female connector 50, the engaging claws 54a rising from the connector pins 54 engage with the engaging holes 56 of the female connector 50, so that the cables 53 are reliably prevented from coming off. In this case, multiple cables 53 only need to be inserted into insertion ports 52 with the same numbers as those assigned to insertion ports 52 of female connector 50, thereby reducing the possibility of cables 53 being inserted incorrectly, and multiple cables 53 can be correctly inserted and secured into insertion ports 52 of female connector 50.

[0049] However, even if the cable 53 should be mistakenly inserted, the mistaken cable 53 can be immediately found from the number given to it and the number given to the female connector 50, and the mistaken cable 53 can be easily pulled out in the following manner.

[0050] That is, for example, if the cable 53 on the right side shown in Fig. 9(a) is misinserted, the claw action part 20 is moved as shown in Fig. 10(b) from the number given to the insertion port 52 into which the cable 53 is inserted to the position given the number of the insertion port 52 where the misinsertion of the cable 53 has occurred, and the claw action part 20 is fixed at that position as shown in Fig. 10(a). Then, from this state, when the pushing part 26 of the claw action part 20 is pushed in the direction of the arrow (leftward) in Fig. 9(b), the pushing part 26 and the claw pressing part 27 move in the same direction (leftward) against the biasing force of the coil spring 29 from the position shown by the chain line. Then, the claw holding portion 27 passes through the engagement hole 56 of the female connector 50, and its tip presses the engagement claw 54a of the connector pin 54, causing it to be embedded inside the connector pin 54, so that the engagement of the engagement claw 54a with the engagement hole 56 is released and the inserted cable 53 can be easily pulled out in the direction of the arrow (upward) as shown in Figure 9(b).

[0051] Then, the correct cable 53 is inserted in place of the incorrectly inserted cable 53 into the insertion port 52 of the female connector 50 in the manner shown in FIGS. 8(a) to 8(c) and fixed in place.

[0052] As is clear from the above description, when the connector jig 1 according to the present invention is used, the cable 53 can be correctly inserted into the insertion port 52 of the female connector 50 while referring to the identification marks M1 and M2 attached to the base 10, so that the cable 53 can be reliably prevented from being inserted incorrectly, and the cable 53 can always be correctly inserted and fixed into the insertion port 52 of the female connector 50. Even if the cable 53 is inserted incorrectly or the engagement claw 54a is damaged or deformed, the claw action part 20 provided on the connector jig 1 acts on the engagement claw 54a of the connector pin 54 to release the engagement of the engagement claw 54a with the engagement hole 56, so that the cable 53 can be easily pulled out. In this case, the cable 53 to be pulled out can be easily identified by the identification marks M1 and M2, and the claw action part 20 can be moved to the position of the cable 53 and fixed by the fixing part 30, so that the operation of pulling out the cable 53 can be performed quickly and with good workability in a short time.

[0053] Therefore, according to the present invention, a single connector jig 1 can be used to prevent the cable 53 from being inserted incorrectly into the female connector 50, and to easily and quickly remove the cable 53 that has been inserted incorrectly from the female connector 50.

[0054] In the above embodiment, an example has been described in which cable 53 is inserted into insertion port 52 of female connector 50 from above, but cable 53 may be inserted not only from above, but also from the side or at an angle.

[0055] In addition, in the above embodiment, an example has been described in which a female connector 50 is accommodated in the connector accommodating portion 11 of the base 10 of the connector jig 1, but a male connector 40 may also be accommodated in the connector accommodating portion 11 of the connector jig 1.

[0056] In addition, the present invention is not limited to the application of the embodiments described above, and various modifications are possible within the scope of the claims and the technical ideas described in the specification and drawings. [Explanation of symbols]
