Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This application applies to shielded flat members (e.g. printed circuit boards) provided with conductive patterns. Ideas for connectors used to connect wires (including coaxial cables) It is.

0002

[Conventional technology]

A shielded wire is connected to a conductive pattern provided on a flat member such as a printed circuit board. For example, you can strip the tip of the wire and pull out the core wire and shield wire. , directly to the conductive pattern (or contact provided on the conductive pattern). Soldering method, or terminating the shielded wire and inserting a connector. There is a known method for making connections.

0003 However, in the former case, it is time-consuming to strip and process the ends of the wires, and it is difficult to connect them. The attachment strength of the connection point is weak, and the printed circuit board and wire cannot be attached or detached, making assembly difficult. Otherwise, it was extremely inconvenient to transport. In the latter method, the tip of the wire (Core wire, shield wire) and the feeding point or ground on the flat member becomes longer. Therefore, impedance matching is required when handling high frequency signals (radio waves). There is a risk that the There was an inconvenience in that it was not possible to attach and detach the wire rod that had been wired from the printed circuit board, etc.

【Example】

FIG. 1 shows an exploded view of a connector according to an embodiment of the present invention. Connect as shown. The first housing 20 accommodates the tip of the shielded wire 10; A second housing 30 that accommodates and holds the first housing, and a printed circuit board, etc. Conductive patterns attached on the conductive patterns 101 and 102 provided on the planar member 100 It consists of a pair of electrically conductive mounting fittings 60, 60'.

[0007] FIG. 2 shows details of the terminal end of the coaxial cable housed in the first housing. As shown in the figure, the first contact (insulation contact) 40 is connected to the core wire 1 of the coaxial cable. The first coating 11a is pierced to contact the core wire, and a second contact (crimped contact ) 50 caulks the shield wire 12. The second contact also includes the wire The outer sheath 12 is caulked so that the cross section of the caulked part becomes approximately rectangular. do.

[0008] Each of the first and second contacts is externally accessible and can be accessed via an arrangement described below. In order to connect to the second holding part 62, 62' of the fitting, the insulation displacement contact and the crimp The bodies 41 and 51 with the contacts are exposed to the outside from the side of the first housing. .

[0009] The pressure contact and crimp contact are connected to each other before being attached to the wire. It is a single contact, and its continuous portion is separated when attached to the wire.

0010 The first housing has an upper half 21 and a lower half 22 at the top, as shown in FIG. It has a structure in which it is connected at a portion 23. However, the present invention is not limited to this, and the upper half The lower half and the lower half may be separated from each other. This pair of upper and lower housings The inside of the half member corresponds to the external shape of the pressure contact and the crimp contact. It has a hollow. 22A shown in the figure has both of these contacts exposed to the outside as described above. It is a groove for letting out.

[0011] Returning to FIG. provided on the turns 101, 102, each with at least one location 63, 63'. Solder by making surface contact with the conductive pattern. The mounting bracket includes first holding parts 61 and 61' that hold the second housing. , in contact with the bodies 41 and 51 of the pressure contact and the pressure contact, and It has second holding parts 62, 62' that hold the contacts and crimp contacts.

0012 Figure 4 shows the second housing attached to the soldered mounting bracket of the flat member. Indicates the condition. As shown in the figure, the second holding parts 62, 62' of the mounting bracket are protrudes into the cavity 31 of the second housing, and the first When the housing is stored, this second holding part is attached to the The first and second contacts 41 and 51 are contacted and held.

[0013] Figures 5 to 7 show the mounting bracket for the housing containing the shielded wire. The state shown is that it is attached and held. Figure 5 is a partially cutaway perspective view, Figure 6 is Figure 5. FIG. 7 is a sectional view taken along line BB.

[0014] In the illustration, the first housing includes a top portion 24 and a pair of opposing outer wall surfaces 26; 26, and the second housing has a bottomless structure and is connected to the first housing. It has a pair of outer wall surfaces 32, 32 that engage with the outer wall surfaces 26, 26. Note that the second how The housing is located inside the outer wall surfaces 32, 32 and together with the outer wall surfaces, the first housing It has a pair of inner wall surfaces 31, 31 that guide the outer wall surface to the groove (see Fig. 1).

【effect】

The structure of the present invention has been explained in detail above, and the structure has the following unique effects. do.

[0016] The connector according to the present invention has a first connector that presses a core wire of a shielded wire. The tact and the second contact crimped with the shield wire of the wire are each attached to the body. These core wires and shield wires are effectively directly attached by contacting the holding part of the mounting bracket. The distance between the wire and the feed point and ground should be kept very short. Therefore, the shape of the tip of the terminated wire should be made low profile. The wire rod and the planar member can be connected without disturbing the matching impedance.

[0017] The crimp contact of the present invention crimps the shield wire of the wire, and Caulk the outer sheath of the wire so that the cross section of the caulked part is approximately rectangular. Ru. Therefore, the terminated wire does not transmit the twist of the wire to the pressure contact at the tip. stomach. In addition, by making the cross section of the crimp contact rectangular, the wire material can be It has directionality in the direction of rotation. Therefore, when storing the wire in a housing, You can avoid the trouble of storing things in the wrong direction.

[0018] In addition, the connector of the present invention has a first housing that houses the wire rod, and a second housing that houses the wire rod. Since the structure fits inside the housing, even before the two housings are mated, the wire Provide adequate protection for the contact pairs connected to the core wire and shield wire from the outside. .

[0019] Furthermore, the second housing is held on the mounting bracket, and the first housing containing the wire rod is attached. By attaching and detaching the housing to this second housing, the wire rod side and the flat member side can be separated. and can be removed at will.

[0020] Also, when the first housing is fitted into the second housing, the first and second housings are connected simultaneously. Since the second contact acts to connect to the second holding part of the fitting, the corresponding The second housing has a guide for correctly guiding the contact to the holding part of the sheet metal fitting. Becomes an id. Therefore, when connecting and disconnecting the connector on the wire side with the connector on the flat member side, Inconveniences such as the contact prying the holding part can be eliminated.
