Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector having a connector main body having a built-in contact piece and a tubular shield frame that is fitted into the connector main body in a fitting manner.

[0002]

[Prior art]

 In this type of connector, if the connector body and the shield frame are distributed separately without being assembled, it is necessary to handle the shield frame as a single item during distribution or mounting on the wiring board. In addition, the shield frame manufactured by punching or bending a thin plate material is likely to suffer from an inconvenience such as being deformed due to an impact during handling.

Therefore, in order to eliminate such an inconvenience as much as possible, a shield frame is preliminarily pre-assembled to circulate a finished product assembled to a connector main body, or the finished product is mounted on a wiring board.

FIG. 12 shows a conventional connector C mounted on the wiring board P. The shield frame 110 of the connector C includes an obliquely upward engaging claw 111 formed on a side plate and a contact piece 112 having a spring property formed at a lower end portion thereof, and has a recessed shape formed on the connector body 100. The shield frame 110 is prevented from coming off due to the engagement between the engaging portion 101 and the locking claw 111, and the contact piece 112 comes into pressure contact with the wiring board P when mounted on the wiring board P. There is.

[0005]

[Problems to be solved by the device]

 When mounting the completed product of the connector C of FIG. 12 on the wiring board P, the contact piece 112 of the shield frame 110 is pressed against the wiring board P to bend it, and in this state, the terminals 102 and the wiring board P are soldered. To be done. However, when the soldering is performed, the elastic restoring force F of the contact piece 112 is applied in the direction of lifting the connector C, so that the terminals 102 and the wiring board P are soldered together when the connector body 100 is lifted from the wiring board P. If such a situation occurs, the contact piece 112 is less likely to bend and the contact pressure against the wiring board P may be insufficient.

The present invention has been made in view of the above circumstances, and a shield frame is provided together with a connector body by enabling distribution and mounting on a wiring board with a shield frame temporarily inserted in the connector body. It is an object of the present invention to provide a connector that can be handled as a unit and that does not cause a shortage of contact pressure of a contact piece with respect to a wiring board that occurs when the connector body rises from the wiring board.

[0007]

[Means for Solving the Problems]

 The connector according to claim 1 has a connector main body having a built-in contact piece, and a shield frame which is formed in a tubular shape with upper and lower ends opened and is fitted to the connector main body in a fitting manner. In a connector in which a contact piece to be pressed against the wiring board is formed at the lower end of the side plate, the temporary locking pawl and the final locking pawl are provided obliquely upward on the side plate of the shield frame. On the other hand, the above-mentioned contact piece is pushed into the connector main body at the temporary insertion position where the above-mentioned contact piece does not project from the lower end of the connector main body, and the upper end of the above-mentioned temporary stop locking claw of the shield frame engages with the temporary stop engaging part. And a full-stop engaging portion with which the upper end of the full-stop locking claw of the shield frame pushed into the full-insertion position where the contact piece projects from the lower end of the connector body is engaged. Together with the above While the tongue piece that is displaced inward and is in the normal position is formed in the tilted posture in the downward direction in the rear frame, the shield frame is pushed into the temporary insertion position in the connector body. Occasionally, a stepped surface that abuts the lower end of the tongue piece in a downwardly sloping posture to prevent the shield frame from being inserted, and the tongue piece that is provided adjacent to this stepped surface is displaced inward. It has a recess that allows the insertion of the tongue when it is in the normal position.

According to a second aspect of the present invention, in the connector according to the first aspect, the tongue portion abutting the stepped surface is provided outside the abutting portion with the lower end of the tongue portion on the stepped surface. It has a rising stopper that prevents the lower end from displacing outward.

According to a third aspect of the present invention, in the connector according to the first or second aspect, the shield frame is formed in a tubular shape having a pair of side plates positioned on the left and right sides and the front and rear sides. An inwardly bent edge is provided at the upper opening edge of the at least one side plate and is separated from the other two adjacent side plates on both sides thereof, and the upper end edge of the one side plate is It is connected to the edge of the ear and forms a tongue piece.

According to a fourth aspect of the present invention, in the connector according to the third aspect, the tongue pieces are provided with protrusions that face inward at both end edges, and the shield frame is provided at a temporary insertion position of the connector body. When the lower end of the tongue piece is pushed in and faces the stepped surface of the connector body, only the tip of the above-mentioned protruding piece of the other two side plates adjacent to each other on both sides of the side plate forming the tongue piece. It is designed to overlap the end edges, and when the tongue piece is in the normal position in which it is displaced inward, the entire projecting piece overlaps the end edges of the other two side plates. .

[0011]

[Action]

 According to the connector of the invention as set forth in claim 1, the connector main body is engaged by the engagement between the upper end of the temporary locking engaging claw of the shield frame temporarily inserted in the connector main body and the temporary locking engaging portion of the connector main body. The shield frame is prevented from coming off. When the shield frame is pushed into the temporary insertion position, even if the shield frame is about to be pushed further in, the lower end of the tongue piece formed on the shield frame in the downward sloping and tilted position becomes the stepped surface of the connector body. Since it prevents the shield frame from being inserted by hitting, the situation in which the shield frame is accidentally pushed from the temporary insertion position to the main insertion position does not occur. In addition, since the contact piece of the temporarily inserted shield frame does not protrude from the lower end of the connector body, it is less likely to be impacted by contact with other objects, and at the same time, the shield frame is backed up by the connector body. Reinforced to prevent deformation.

Attach the connector body with the shield frame temporarily inserted to the wiring board and fix it so that the connector body does not float up from the wiring board.After that, displace the tongue piece of the shield frame inward and make it normal. When the shield frame is pushed into the main insertion position after the posture, the tongue piece is inserted into the recess on the connector body side, and the contact piece of the shield frame is bent and pressed against the wiring board. In this fully inserted state, the upper end of the main-stop locking claw of the shield frame is locked to the main-stop engaging portion of the connector main body, so that the shield frame and the connector main body are coupled. At this time, since the connector body is already fixed so as not to float on the wiring board, even if the restoring force of the contact piece is applied in the direction of lifting the connector body, the connector body does not float up from the wiring board.

According to the connector of the invention as defined in claim 2, a large pushing force is applied to the shield frame temporarily inserted in the connector body so that the lower end of the tongue portion in the downwardly spread and inclined posture is on the stepped surface. Even if the lower end of the tongue piece slides outward and the lower end of the tongue piece part is further displaced outward, the displacement of the lower end of the tongue piece part is blocked by the stopper part on the connector body side, so that the tongue piece part expands and deforms. Is prevented.

According to the connector of the invention as set forth in claim 3, since the tongue piece is formed over the entire predetermined side plate of the shield frame, the size of the tongue piece can be increased. Therefore, when the shield frame temporarily inserted in the connector body is fully inserted, it becomes easy to displace the tongue piece part to the regular position with the fingers of the hand.

According to the connector of the invention as defined in claim 4, when the shield frame is temporarily inserted in the connector body, the opening deformation of the two side plates adjacent to each other on both sides of the side plate forming the tongue portion. Are prevented by the tips of the projecting pieces that overlap the edges of the two side plates. Further, when the shield frame is fully inserted in the connector body, since the entire projecting piece overlaps the end edge portions of the two side plates, the side plate forming the tongue piece and the two side plates on both sides of the side plate form. The gap is closed by the protrusion, which helps improve the shield performance of the shield frame.

Reference numeral 24 is a protrusion for positioning the connector body 1 at a predetermined position on the wiring board P during mounting.

The shield frame 3 is formed by bending a thin metal plate punched into a predetermined shape to form a rectangular tube shape having open upper and lower ends. As shown in FIG. 1, FIG. 2 and FIG. 7 and the like, or as can be inferred from those figures, the protruding portions protruding outward are provided on the lower half portions of the left end portion and the right end portion of the shield frame 3, respectively. 34 are provided, and a large number of curved contact pieces 31 protruding outward are formed at the lower ends of the protrusions 34. Further, on the front side plate 3a and the rear side plate 3b of the shield frame 3, respectively, a temporary provisional locking pawl 32 and a final locking pawl 33, which are formed by cutting and bending inward, are slanted upward. It is provided in. Further, also in the projecting portion 34, a main stop locking claw 33 'formed by cutting and raising inwardly is provided in the front side plate 3a and the rear side plate 3b in an obliquely upward direction. In addition, a projecting piece 35 formed by cutting and raising outward is provided at a proper position on the front side plate 3a of the shield frame 3 in a diagonally downward direction.

As shown in FIGS. 1, 2 and 6, the shield frame 3 is formed with two tongue pieces 4 and 4 in a downwardly spread and inclined posture. These tongue pieces 4 and 4 are displaced inward to take the normal postures shown in FIGS. 7 and 11. In the illustrated example, the tongue pieces 4 and 4 are formed by using a pair of left and right side plates of the shield frame 3, that is, the entire left side plate 3c and right side plate 3d. That is, the shield frame 3 is provided with an inwardly bent edge 36 at the upper opening edge, and the left side plate 3c and the right side plate 3d are connected to the front side plate 3a and the rear side plate 3b which are adjacent to each other on both sides thereof. And the upper edge portions of the left side plate 3c and the right side plate 3d are connected to the edge 36 to form the tongue pieces 4, 4. If the shield frame 3 is formed in a square tube shape and the tongue pieces 4, 4 are formed by using the entire left side plate 3c and right side plate 3d as described above, a thin plate material punched into a predetermined shape is formed into a square tube shape. Since the shield frame 3 can be formed only by bending, there is an advantage that it is not necessary to perform a method requiring a high technology such as drawing when manufacturing the shield frame 3 having a rectangular cylindrical shape. Each of the tongue pieces 4 is provided with inwardly projecting projections 37 on both side edge portions thereof, whereas each of the front side plate 3a and the rear side plate 3b corresponding to these projecting pieces 37 is provided. A recessed projecting piece receiving portion 38 is formed at the end edge portion. Then, when the tongue piece portion 4 is kept in the downward inclined posture, only the tip end portion of the projecting piece 37 overlaps with the projecting piece receiving portion 38 as shown in FIGS. 1 and 2.

Here, the temporary locking engaging claw 32 and the tongue portion 4 on the side of the shield frame 3 and the temporary locking engaging portion 12 and the stepped surface 18 on the side of the connector body 1 are the shield frame 3 Is temporarily fixed to the temporary insertion position of the connector main body 1, and the locking claws 33, 33 'for permanent locking on the shield frame 3 side and the permanent locking engaging portions 13, 13' on the connector main body 1 side are shielded. It is useful for permanently fixing the frame 3 to the main insertion position of the connector main body 1, and the recess 19 on the connector main body 1 side allows the tongue piece 4 to be pushed when the shield frame 3 is pushed from the temporary insertion position to the main insertion position. Helps to house.

In order to temporarily fix the shield frame 3 at the temporary insertion position so that the shield frame 3 can be permanently fixed at the final insertion position, the upper end of the temporary locking claw 32 when the shield frame 3 is pushed to the temporary insertion position. The temporary fastening engaging portion 12 is formed at the position, and the final fastening engaging portions 13 and 13 ′ are provided at the tip positions of the final fastening engaging claws 33 and 33 ′ when the shield frame 3 is pushed to the regular insertion position. It is sufficient to form the level difference between the temporary fixing locking claw 32 and the final fixing locking claws 33, 33 ', the temporary fixing engaging portion 12, the final fixing engaging portion 13, This can be achieved by relatively setting the level difference of 13 '.

When the shield frame 3 is pushed to the temporary insertion position and about half its height is fitted to the connector body 1, as shown in the left half of FIGS. 1 and 3, the shield frame 3 is temporarily fixed. The upper end of the locking pawl 32 is engaged with the temporary fixing engagement portion 12 of the connector body 1. Further, as shown in FIGS. 1 and 6, the lower end of the tongue piece 4 abuts on the stepped surface 18. Then, in this temporary insertion state, as shown in the right half of FIG. 3 and FIG. 4, the inner surfaces of the locking pieces 33, 33 ′ for final locking guide the climbing portions 13, 13 ′ for final locking. It opposes the surfaces 13c, 13c 'in a contact state or in a state of being slightly separated. In this case, the lower end of the tongue portion 4 may be opposed to the stepped surface 18 with a small gap, but if it is so arranged, it will be temporary when it is abutting. Since the retaining locking claw 32 and the tongue portion 4 are not sandwiched between the temporary retaining engaging portion 12 and the stepped surface 18 and positioned vertically, the shield frame 3 and the connector body 1 are not exerted. Since slight rattling is generated between the tongue piece 4 and the stepped surface 18 in order to prevent inconvenience caused by rattling, for example, damage to the outer surface of the connector body 1 and deformation of the shield frame 3. It is desirable to make it hit against. Even when the inner surfaces of the final locking engagement pieces 33, 33 'are brought into contact with the inner surfaces 13c, 13c' of the final locking engagement portions 13, 13 ', the rattling as described above occurs. It is effective in preventing the inconvenience.

When the shield frame 3 is temporarily inserted, the contact piece 31 of the shield frame 3 does not project from the lower end of the connector body 1, and the projecting piece 35 has its lower end inside the cover portion 10 as shown in FIG. It faces the spaces 10a and 10b.

In such a temporary insertion state, the upper end of the temporary locking engaging claw 32 and the temporary locking engaging portion 12 are engaged to prevent the shield frame 3 from being detached upward from the connector body 1. It Further, when an external force in the pushing direction is applied to the shield frame 3, the lower end of the tongue portion 4 abuts on the stepped surface 18, so that the shield frame 3 is not pushed in. Therefore, a situation in which the shield frame 3 is inadvertently pushed from the temporary insertion position to the main insertion position is prevented. Moreover, even if a large pushing force is applied to the shield frame 3 and the lower end of the tongue piece 4 in the downwardly spread and inclined posture tries to slide outward on the stepped surface 18, the lower end of the tongue piece 4 is pushed. Since the displacement is blocked by the stopper portion 18a, the spread deformation of the tongue portion 4 is reliably prevented. Further, since the front side plate 3a and the rear side plate 3b of the shield frame 3 are sandwiched by the tip portions of the protrusions 37, 37 provided on the tongue portion 4, the front side plate 3a and the rear side plate 3b are opened. Deformation is prevented. In addition, since the contact piece 31 does not project from the lower end of the connector body 1, the contact piece 31 is unlikely to come into contact with other objects, which makes the contact piece 31 less likely to be impacted during handling, so that the contact piece 31 is not deformed. To be prevented. Furthermore, the shield frame 3 itself is backed up and reinforced by the connector body 1, so that the shield frame 3 is prevented from being deformed in advance.

When the shield frame 3 is pushed into the main insertion position, the left and right tongue pieces 4, 4 of the shield frame 3 are pinched with fingers of the hand to displace the tongue pieces 4, 4 inward. When the shield frame 3 is pushed downward from that state, as shown in FIG. 7, FIG. 8 and FIG. 13 'rides over the ride-up guide surfaces 13c, 13c' and engages with the main engagement engaging portions 13, 13 ', and at the same time, the tongue pieces 4, 4 are inserted into the recesses 19 as shown in FIG. To be done. Further, as shown in FIG. 10, the projecting piece 35 is housed in the inner spaces 10 a and 10 b of the cover part 10. The work of displacing the tongue pieces 4, 4 inward to bring them into the normal posture is easy because the tongue pieces 4, 4 are largely formed by the left side plate 3c and the right side plate 3d of the shield frame 3. . Further, when the shield frame 3 is fully inserted, the projecting pieces 37 are entirely overlapped with the projecting piece receiving portions 38 of the front side plate 3a and the rear side plate 3b, and the left side plate 3c and the right side plate 3d are entirely overlapped. Since the gap between the formed tongue pieces 4, 4 and the front side plate 3s or the rear side plate 3b is eliminated, the shield performance of the shield frame 3 is improved.

When the shield frame 3 is pushed to the main insertion position and the entire height of the shield frame 3 is fitted to the connector main body 1, the edge 36 of the shield frame 3 of the opening 11 of the connector main body 1 is as shown in FIGS. 7, 8 and 10. Press the peripheral edge. Therefore, in this fully inserted state, the shield frame 3 is securely fixed to the connector body 1 by the pinching action of the connector body 1 by the upper ends of the locking claws 33, 33 ′ for final locking and the edge 36. The contact piece 31 projects from the lower end of the connector body 1 when the shield frame 3 is pushed to the main insertion position.

The above-described connector C is provided for handling at the distribution stage or at the time of mounting on the wiring board P in a state where the shield frame 3 is temporarily fixed to the connector body 1 at the temporary insertion position. By doing so, deformation of the shield frame 3 and its contact piece 31 is prevented. Further, when mounting on the wiring board P, the terminals 23 are soldered to the wiring board P while the shield frame 3 is temporarily fixed, and then the shield frame 3 is pushed to the main insertion position and contacted as shown in FIG. The piece 31 is pressed against the wiring board P to bend it and obtain a necessary contact pressure.

In this embodiment, the contact piece 31 is provided only on the lower end portion of the protruding portion 34 of the shield frame 9, but in order to improve the shield performance, the contact piece 31 is provided over the entire lower end portion of the shield frame 9. It is desirable to provide. Further, the numbers of the temporary locking claws and the temporary locking engaging parts, the final locking locking claws and the permanent locking engaging parts, etc. are not limited to the embodiments, and the places where they are provided are also limited to the embodiments. Not done.

[Effect of device]

 According to the first aspect of the present invention, it is possible to temporarily insert the shield frame into the connector body in a state where it is difficult to remove the connector body, and in the provisionally inserted state, the connector body and the shield frame are made to flow as an integrated body. Since it can be attached to a wiring board or a wiring board, the inconvenience of handling the shield frame as a single item is eliminated, and at the same time, the shield frame and its contact pieces are less likely to be deformed or damaged. Further, even if a large pushing force is applied to the shield frame temporarily inserted in the connector body, the lower end of the tongue portion of the shield frame hits the stepped surface of the connector body to prevent the shield frame from being fully inserted. It is possible to reliably prevent the situation where the shield frame is mistakenly inserted during distribution or when it is attached to the wiring board. And, even though it is not necessary to handle the shield frame as a single item, it is possible to keep the contact piece and the wiring board in contact with each other with a sufficiently large contact pressure in the mounted state.

According to the second aspect of the invention, the spread deformation of the tongue portion is prevented by the stopper portion on the connector body side when a large pushing force is applied to the shield frame temporarily inserted in the connector body. Therefore, there is an effect that it is possible to prevent the generation of defective products due to the expansion deformation of the tongue piece.

According to the third aspect of the invention, since the tongue piece of the shield frame temporarily inserted in the connector body is easily displaced to the regular position by the finger of the hand, the shield frame is moved from the temporary insertion position to the main insertion position. Improves workability when pushed into.

According to the invention of claim 4, when the shield frame is temporarily inserted, the two side plates adjacent to each other on both sides of the side plate forming the tongue portion are not only easily opened and deformed, but also When the shield frame is fully inserted, the projecting piece closes the gap between the side plate forming the tongue piece and the two side plates on both sides of the side plate, thereby improving the shield performance.
