The cable connection structure includes a connection terminal 10, a circuit board 20, a base plate 30, a positioning abutting part 40, and a cable clamp 50. The connection terminal 10 is attached to a braided wire 3 of a coaxial cable 1. The circuit board 20 has a signal line connection hole 21 and a ground line connection hole 22. The base plate 30 has a cable insertion hole 31. The positioning abutting part 40 is used for determining the position of the circuit board 20 on the base plate 30. The cable clamp 50 grasps a protective outer cover 4 of the coaxial cable 1, holds a core wire 2 such that the core wire 2 is exposed at a predetermined height position, and holds a connection terminal 10 such that the connection terminal 10 is exposed at a predetermined height position. ## Claims ### Claim 1 A cable connection structure used in a vehicle antenna device, the cable connection structure comprising: a connection terminal attached to a braided wire of a coaxial cable having a core wire as a signal line, the braded wire as a ground line, and a protective outer cover constituting an outermost sheath; a circuit board having a signal line connection hole for the core wire of the coaxial cable and a ground line connection hole for the connection terminal; a base plate on which the circuit board is placed, having a cable insertion hole through which the coaxial cable is inserted; a positioning abutting part for determining the position of the circuit board on the base plate; and a cable clamp grasping the protective outer cover of the coaxial cable, holding the core wire so as to be exposed at a predetermined height position toward the circuit board side for being electrically connected to the signal line connection hole of the circuit board, and holding the connection terminal so as to be exposed at a predetermined height position toward the circuit board side for being electrically connected to the ground line connection hole of the circuit board. ### Claim 2 (depends on 1) The cable connection structure according to claim 1, wherein the cable clamp is disposed between the circuit board and the base plate and is fitted into the cable insertion hole of the base plate from a side on which the circuit board is placed. ### Claim 3 (depends on 1) The cable connection structure according to claim 1, wherein the positioning abutting part is disposed on the base plate. ### Claim 4 (depends on 1) The cable connection structure according to claim 1, wherein the connection terminal functions also as the positioning abutting part by being held through the cable clamp. ### Claim 5 (depends on 1) The cable connection structure according to claim 1, wherein the connection terminal has a blade-shaped part vertically extending with respect to a surface direction of the circuit board, and the ground line connection hole of the circuit board is formed into a slit shape so as to correspond to the blade-shaped part of the connection terminal. ### Claim 6 (depends on 5) The cable connection structure according to claim 5, wherein the ground line connection hole of the circuit board is formed into a slit-like hole elongated parallel to a direction away from the positioning abutting part. ### Claim 7 (depends on 5) The cable connection structure according to claim 5, wherein a tip of the blade-shaped part of the connection terminal is chamfered. ### Claim 8 (depends on 1) The cable connection structure according to claim 1, wherein the connection terminal is crimped to the braided wire of the coaxial cable. ### Claim 9 (depends on 1) The cable connection structure according to claim 1, wherein, when the circuit board is disposed to be parallel to the base plate from a state where the circuit board is inclined with one end thereof abutting on the positioning abutting part and with the other end thereof lifted upward during assembling, the cable clamp holds the core wire and the connection terminal so as to have a height relationship that the connection terminal is inserted into the ground line connection hole before the core wire of the coaxial cable is inserted into the signal line connection hole. ### Claim 10 (depends on 1) The cable connection structure according to claim 1, wherein the cable clamp holds the connection terminal at a side close to the positioning abutting part and the core wire at a side far from the positioning abutting part. ### Claim 11 (depends on 1) The cable connection structure according to claim 1, wherein the circuit board has the ground line connection hole at a side close to the positioning abutting part and the signal line connection hole at a side far from the positioning abutting part. ### Claim 12 (depends on 1) The cable connection structure according to claim 1, wherein the cable clamp has a cable come-off preventing projection that projects toward an outer peripheral surface of the protective outer cover of the coaxial cable so as to prevent the coaxial cable from coming off from the cable clamp. ### Claim 13 (depends on 1) The cable connection structure according to claim 1, wherein the cable clamp has a cable clamp come-off preventing projection that projects toward an inner peripheral surface of the cable insertion hole so as to prevent the cable clamp from coming off from the cable insertion hole of the base plate. ### Claim 14 (depends on 1) The cable connection structure according to claim 1, wherein the cable clamp is formed asymmetric so as to fix a shaft rotation direction thereof fitted into the cable insertion hole to be a predetermined direction.
