[0043] With reference to FIG. 1 to FIG. 5A and FIG. 5B, the pressure contacting connection type contact (below abbreviated as contact) 1 according to one embodiment of the present invention can electrically connect a coaxial cable Cb with a mating side connector, not shown in the drawings. The contact 1 is provided with a connecting terminal 11 and a pressure contacting terminal 12, at a base portion 11t formed in a strip shape. At the connecting terminal 11, the mating side connector can be connected, and at the pressure contacting terminal 12, the central conductor Wb of the coaxial cable Cb can be connected.
[0044] The pair of contacting pieces 11s11s of the connecting terminal 11 extends curvilinearly in a vertical direction from first both side portions lie of one end side of the base portion 11t, the with tip portion side opened in an shape. In this way, the mating side connector, not shown in the drawings, can be inserted inside the pair of contacting pieces 11s11s.
[0045] The pair of contacting pieces 11s11s has a pair of contact points 111111 disposed facing each other at the tip portions of the contacting pieces 11s11s. The pair of contact points 111111 can contact the perimeter of the mating side contact, not shewn in the figures.
[0046] The pressure contacting terminal 12 includes a base end section 12g, pressure contacting pieces 12d12d, and an open angle portion 12a. The base end section 12g has a form, wherein an extending piece extending from second both side portions 11f of the other end side of the base portion 11t is folded such that mutual piece thickness faces are opposed, opposite the other end side of the base portion 11t. The pressure contacting pieces 12d12d, have a form where, from, the base end section 12g, an extending piece extends away from the base portion 11t to the tip portion side such that the piece thickness faces are opposed and in addition, rises obliquely at an opposite side of the protrusion direction of the pair of contacting pieces 11s11s. The open angle portion 12a is formed at the tip portion side of the pair of pressure contacting pieces 12d12d, and has a form such that the central conductor Wc of the coaxial cable Cb can be inserted from an outer direction.
[0047] The open angle portion 12a of the pair of pressure contacting pieces 12d12d herein is opened in a V shape where the opposed piece thickness faces of the extending piece constituting the pressure contacting pieces 12d12d at the tip portion side. In this way, the central conductor Wc of the coaxial cable Cb can be inserted to the open angle portion 12a between the pair of pressure contacting pieces 12d12d from an outer direction thereof (refer to FIG. 4 or FIG. 5B).
[0048] According to the above constitution, the contact 1 according to the present embodiment is provided with a connecting terminal 11 provided at one end side of the base portion 11t with a pair of contacting pieces 11s11s whose tip portion side is opened. Further, the contact 1 according to the present embodiment is provided with a pressure contacting terminal 12 having a pair of pressure contacting pieces 12d12d wherein an extending piece, disposed at an other end side of the base portion 11t, folded such that piece thickness faces are opposed, from the base end section 12g extends away from the base portion 11t to the tip portion side, and also rises obliquely at an opposite side of the protrusion direction of the pair of contacting pieces 11s11s. The open angle portion 12a is constituted at the tips of the pressure contacting pieces 12d12d such that the central conductor Wc of the coaxial cable Cb can be inserted from an outer direction. In this way, in a state wherein the central conductor Wc is inserted between the pair of pressure contacting pieces 12d12d or into the open angle portion 12a, the pair of pressure contacting pieces 12d12d have elasticity or spring characteristics and can hold the central conductor Wc, and therefore, it is possible to provide a pressure contacting connection type contact which is capable of suppressing the creep phenomenon.
[0049] Further, the contact 1 preferably consists of a metal plate having conductivity, and by stamp-processing the metal plate having conductivity, it is possible to obtain a pressure contacting connection type contact of the desired shape. The contact 1 preferably consists of a copper alloy, but is not limited to a copper alloy.
[0050] With reference to FIG. 1 to FIG. 4, the base end section 12g of the pressure contacting terminal 12 may have close contact bent portions 12b12b where the extending piece folded in the same direction as the protrusion direction of the pair of contacting pieces 11s11s is bent to closely contact so as to be approach and oppose the base portion 11t. In this way, it is possible to further strengthen the strength of the base end section 12g of the pair of contact pressure contacting pieces 12d12d. Such a constitution can be produced by fold processing an expansion metal plate having conductivity.
[0051] More specifically, the base end section 12g and the pair of pressure contacting pieces 12d12d of the pressure contacting terminal 12 are constituted by fold processing a symmetrically shaped L shaped extending piece extending from second both side portions 11 of the other end side of the strip shaped base portion 11t. Namely, in the L shaped extending piece, the piece thickness faces of the extending piece of a parallel portion to the lengthwise direction of the strip shaped base portion 11t are folded to be opposed, and the base end section 12g and the pair of pressure contacting pieces 12d12d are formed. Further, the tip portions of the pair of pressure contacting pieces 12d12d rising obliquely from the base end section 12g are positioned to be somewhat higher than the horizontal level of the base portion 11t (refer to FIG. 3B, and FIG. 3C).
[0052] Further, with reference to FIG. 1 to FIG. 5A and FIG. 5B, the open angle portion 12a of the pair of pressure contacting pieces 12d12d has a chamfered portion 12c12c there the tip portion sides of the opposing piece thickness faces are chamfered in an arc shape. In this way, the central conductor Wc can be smoothly inserted between the pair of pressure contacting pieces 12d12d or the open angle portion 12a.

[0088] With reference to each of FIG. 1 to FIG. 15A and FIG. 15B, the coaxial connector 10 is provided with a contact 1 constituted of a connecting terminal 11 having a pair of contacting pieces 11s11s inside which the mating side contact, not shown in the figures, can be inserted, and a pressure contacting terminal 12 provided at an other end side of the base portion 11t, having a pair of pressure contacting pieces 12d12d wherein an extending piece folded such that piece thickness faces are opposed extends from the base end section 12g, away from, the past portion 11t to a tip portion side such that the piece thickness faces are opposed and also rises obliquely at an opposite side of the protrusion direction of the pair of contacting pieces 11s11s. The tips of the pressure contacting pieces 12d12d are constituted with an open angle portion 12a where the central conductor Wc of the coaxial cable Cb can be inserted from an outer direction. In this way, in a state wherein the central conductor Wc is inserted between the pair of pressure contacting pieces 12d12d or into the open angle portion 12a, the pair of pressure contacting pieces 12d12d have elasticity or spring characteristics and can hold the central conductor Wc, and therefore, it is possible to provide a coaxial connector 10 which is capable of suppressing the creep phenomenon.
[0089] With reference to each view of FIG. 6 to FIG. 10, the cable clamp 31 comprises a pair of conductor barrels 31c31c which can crimp the external conductor Wb, a pair of insulation grips 31i31i which can crimp the insulating sheath Wi, and a pair of crimp barrels 31a31a which can crimp the rectangular-shaped accommodating portion 23 via the pair of extended pieces 3333, and therefore, the terminal of the coaxial cable Cb and the coaxial connector 10 can be reliably connected.
[0090] While preferred embodiments of the present invention have been described and illustrated above, it is to be understood that they are exemplary of the invention and are not to be considered to be limiting. Additions, omissions, substitutions, and other modifications can be made thereto without departing from the spirit or scope of the present invention. Accordingly, the invention is not to be considered to be limited by the foregoing description and is only limited by the scope of the appended claims.
