Description

本発明は、主に高周波信号の伝達に使用される同軸ケーブルと電子機器との接続、又は、同軸ケーブル同士の接続に使用するコネクタに関する。   The present invention relates to a connection between a coaxial cable and an electronic device mainly used for transmitting high frequency signals, or a connector used for connecting coaxial cables.

従来、高周波信号の伝達に使用される同軸ケーブルと電子機器との接続、又は、同軸ケーブル同士の接続には、同軸コネクタが使用されている。   Conventionally, a coaxial connector is used to connect a coaxial cable and an electronic device used to transmit a high frequency signal or to connect coaxial cables.

この同軸コネクタは、筒状の接続シェルと、接続シェルと嵌合する筒状の嵌合部を有するシェル基体とを備え、接続シェルとシェル基体とからなるシェル内にコンタクトを保持するインシュレータが収容された構造となっている。   This coaxial connector includes a cylindrical connection shell and a shell base having a cylindrical fitting portion fitted with the connection shell, and an insulator for holding a contact in a shell consisting of the connection shell and the shell base is accommodated The structure is

このシェルは、同軸ケーブルや基板に接続されるダイカスト製のシェル基体と、接続シェルとが別体に備えられ、シェル基体に接続シェルが組み付けられるように構成されている。   The shell is configured such that a die-cast shell base connected to a coaxial cable or substrate and a connection shell are separately provided, and the connection shell is assembled to the shell base.

この種のシェルとしては、例えば、後端側が開口したシェル基体にインシュレータを収容した接続シェルを当該後端側開口より挿入し、シェル基体の嵌合部分と接続シェルとを圧着させる構造のものが知られている。(例えば、特許文献1を参照)。   As a shell of this type, for example, one having a structure in which a connection shell containing an insulator is inserted into a shell base having an opening at the rear end from the opening at the rear end, and the fitting portion of the shell base and the connection shell are crimped Are known. (See, for example, Patent Document 1).

特開2005−294260号公報JP, 2005-294260, A

しかしながら、上述の如き従来技術では、シェル基体と接続シェルとの嵌合部分を圧着するため、圧着時の圧力によって接続シェル及びインシュレータが破損するおそれがあることから、筒状に形成されるシェル基体の嵌合部分を圧着可能且つ破損しない適切な厚みとする加工精度が要求されるという問題があった。   However, in the prior art as described above, since the fitting portion between the shell base and the connection shell is crimped, there is a risk that the connection shell and the insulator may be damaged by the pressure at the time of crimping. There is a problem that a processing accuracy is required to make the fitting portion of the above-mentioned suitable thickness without crimping and breakage.

特に、この種の同軸コネクタを多極化する場合、一つのシェル基体に対し、その端面より突出した複数の筒状の嵌合部を形成し、各嵌合部にそれぞれ接続シェルを組み付ける構造とすることが考えられる。   In particular, in the case of multipolarizing this type of coaxial connector, a plurality of cylindrical fitting parts protruding from the end face are formed on one shell base, and a connecting shell is assembled to each fitting part.

その場合、シェル基体の形状が複雑化することから、鋳造や削り出しによって、筒状に形成されるシェル基体の嵌合部分を圧着可能、且つ、破損しない適切な厚みとすることには高い加工精度が要求されるため、困難性が高く、製造コストも増加するおそれがあった。   In that case, since the shape of the shell base becomes complicated, high processing can be performed to make the fitting portion of the shell base formed in a cylindrical shape by crimping or cutting-off possible and to have an appropriate thickness without breakage. Since accuracy is required, the difficulty is high, and the manufacturing cost may be increased.

その際、抜け止め片20,20の加締めは、抜け止め片20,20を抜け止め係止部301の奥側(シェル基体本体31側)に折り曲げるだけでよく、嵌合部30及びその中のインシュレータ5に対し圧力が作用しないようになっている。 At that time, caulking of the retaining pieces 20, 20 is sufficient only by bending the retaining pieces 20, 20 to the back side (the shell base body 31 side) of the retaining member 301, and the fitting portion 30 and the inside thereof The pressure does not act on the insulator 5 of FIG.

コンタクト4は、導電金属材により一体に形成され、コネクタ1接続方向に向けたピン状のコンタクト本体41と、コンタクト本体41の後端より下向きに延出された基板接続部42とを備え、L字状を成している。尚、上段側と下段側とでは、コンタクト本体41及び基板接続部42の長さが異なっている。   The contact 4 is integrally formed of a conductive metal material, and includes a pin-shaped contact main body 41 directed in the connector 1 connecting direction, and a board connection portion 42 extending downward from the rear end of the contact main body 41 It has a letter shape. The lengths of the contact main body 41 and the substrate connection portion 42 are different between the upper stage side and the lower stage side.

インシュレータ5は、絶縁樹脂により形成され、コネクタ接続方向に長いコンタクト保持部51と、コンタクト保持部51の後端より下向きに延出された基板接続部収容部52とを備え、側面視L字状を成している。   The insulator 5 is formed of an insulating resin, and includes a contact holding portion 51 which is long in the connector connecting direction, and a board connection portion accommodating portion 52 which extends downward from the rear end of the contact holding portion 51. The

このインシュレータ5は、コンタクト保持部51に前後方向に貫通したコンタクト挿入孔511を有するとともに、コンタクト挿入孔511の後端側と連通し、且つ、下面側に開放された溝状の基板接続部収容溝521を有し、コンタクト4をインシュレータ5の後端側より圧入し、コンタクト本体41をコンタクト挿入孔511に挿通させ、コンタクト本体41の先端をコンタクト保持部51の先端より突出させるとともに、基板接続部収容溝521に基板接続部42が保持されることによってコンタクト4と一体化されている。   The insulator 5 has a contact insertion hole 511 penetrating in the front-rear direction in the contact holding portion 51, and communicates with the rear end side of the contact insertion hole 511, and receives a grooved substrate connection portion opened on the lower surface side. It has a groove 521, press-fits the contact 4 from the rear end side of the insulator 5, inserts the contact main body 41 into the contact insertion hole 511, causes the tip of the contact main body 41 to protrude from the tip of the contact holding portion 51, and The substrate connecting portion 42 is held in the portion accommodating groove 521 so as to be integrated with the contact 4.
