The signal line 44a of the shielded cable 44 is exposed, and a signal line insertion groove 45 formed in the holding block 45 is formed.
a. Then, by holding the holding block 45 holding the signal line 44 a from above the insulating block 42, the signal line 44 a of the signal line insertion groove is connected by pressure to the pressure contact piece 43 a of the inner conductor 43.
Further, the upper surface of the outer conductor 41 is opened from the center to the rear end in order to overlap the holding block 45 on the insulating block 42 from above, but a shield for blocking the inflow and outflow of noise from this opening portion.

れるという問題があった。However, in such a connection structure in which the signal line of the shielded cable is pressed against the inner conductor of the shielded connector, the pressure contact piece is erected perpendicularly to the axial direction of the connector. In addition, since a space for connecting the signal line to the pressure contact piece from above is required, there is a problem that the entire connector becomes long and miniaturization is hindered.

Therefore, it is necessary to cover the opening with a shield cover to secure the shielding property, so that the number of constituent parts increases. As a result, there has been a problem that improvement in assembly workability is hindered.

続されてなることを要旨とするものである。According to the present invention, there is provided a connection structure for a shielded connector, wherein an insulated core wire holding member for bending and holding a core wire connection terminal of a shielded cable downward is attached to a shell frame. The cylindrical outer conductor fitted and connected to the shell frame is provided with an inner conductor via an insulating inner conductor insertion member, and the inner conductor is pressed against a downwardly bent portion of the core wire connection terminal of the cable. A pressure contact portion to be connected is provided, the core wire holding member of the shell frame body is abutted against the inner conductor insertion member of the outer conductor, and the downward bent portion of the core wire connection terminal of the cable is press-connected to the press contact portion of the inner conductor. The gist of this is.

ことができる。[0011] According to the shield connector connection structure of the present invention having the above structure, the core connection terminal of the shielded cable is bent downward and held, and the bent portion and the press contact portion provided on the inner conductor are axially connected. Since the pressure contact connection is made to face each other, it is possible to make a pressure connection in a connection space that is short with respect to the axial length of the connector. Since a member such as a shield cover for closing the portion is not required, the number of parts is small, the workability of terminal processing is improved, and the size can be reduced.

Since it can be formed, the manufacturing cost can be reduced.

することができるので、シールド性も向上する。Further, if the crimping portion for crimping the shield cable and the jacket of the shielded cable is provided integrally with the shell frame, the outer conductor and the crimping portion are formed separately.
Since the outer conductor can sufficiently cover the core wire, which is the signal line exposed from the connection terminal of the shielded cable, as compared with the related art, the shielding property is also improved.

When the present invention is applied to a coaxial shielded cable, it can be implemented without using a deformed material only by changing the thickness of the shell frame having the crimped portion to be thin. That is, by changing only the shell frame, the present invention can be applied to various types of shielded cables.

できる。As described above, the shield connector is constructed by integrally assembling the outer conductor, the inner conductor, the inner conductor insertion member, the core wire holding member, the shell frame, and the shielded cable, and has such a structure. The shielded structure of the shielded connector has a structure in which the core connection terminal of the shielded cable is bent downward and held, and the bent portion and the press-contact portion provided on the inner conductor are axially opposed to each other so as to press-connect. Since the pressing direction and the axial direction of the cable are the same, the space for the pressing connection in the axial direction of the connector is shorter than that of the prior art. In addition, a simple-shaped inner conductor having the above-described press-contact portion can be applied. Furthermore, since the crimping section with the shielded wire inverted is crimped and fixed with the crimping piece on the shielded cable jacket, it is further compared with the conventional technique of crimping and fixing the shielded wire and cable separately. Connection space can be shortened.

設ける必要もなく遮蔽性が良い。In addition, since the crimping portion for crimping and fixing the shielded cable is provided integrally with the shell frame, the outer conductor and the crimping portion can be formed separately, so that the outer conductor is exposed from the connection terminal of the shielded cable. Since the core portion, which is a signal line, can be formed so as to be sufficiently covered by the outer wall of the outer conductor, there is no need to separately provide a shield cover as in the related art, and the shielding property is good.

汎用性がある。Similarly, when the outer conductor and the crimping portion are formed separately, when the present invention is applied to a small-diameter coaxial shielded cable, the thickness of the shell frame having the crimping portion can be simply reduced. It can be applied without using a profile. In other words, by changing only this shell frame, it can be applied to various types of shielded cables,
There is versatility.

る。シールド性も向上して低コスト化が可能になる。According to the shield connector connection structure of the present invention, the core connection terminal of the shielded cable is bent downward and held, and the bent portion and the press contact portion provided on the inner conductor are axially opposed to each other. Since the pressure contact connection is made, it is possible to press-connect in a connection space that is short with respect to the axial length of the connector. Since no member such as a shield cover for closing is required, the number of parts is small, the workability of terminal processing is improved, and the size can be reduced. The shielding performance is also improved, and the cost can be reduced.
