Abstract
The invention discloses a jack contact element and an electrical connector for a narrow installation space. The electrical connector comprises an insulator and the jack contact element arranged in the insulator, wherein the jack contact element comprises a switching sleeve and a jack which is arranged in the switching sleeve and matched with a contact pin; the switching sleeve comprises a sleeve provided with the jack and a wiring handle which radially and integrally extends along the jack from the periphery surface of the sleeve and is connected with a cable. The wiring handle radially extends along the jack from the periphery surface of the sleeve of the jack contact element, the cable connected with the contact element prevents the axial interlacement and interference with the jack by the wiring handle, and the wiring end has no axial size, therefore, the axial size of the jack can be completely matched with the size of the corresponding contact pin, and the additional axial wiring end size is not increased; accordingly, the jack contact element can effectively utilize the installation space and realize the connecting function of products in a narrow space in the plugging direction.
Description
Technical field
The present invention relates to technical field of electric connectors.
Background technology
Used jack contact in the existing electric connector; One end is to be used for the jack that extends along the grafting direction that cooperates with contact pin; The other end is the welding pin that is used for the terminals of termination cable or is used for being connected with circuit board; And the terminals of tool jack contact extend axially along its jack mostly, make cable come to peg graft to being oppositely arranged, the size that the axial dimension of the jack contact of this structure is promptly pegged graft on the direction is bigger; Add the size of connector shell, cause existing jack contact or electric connector to be difficult to the narrow and small occasion use of installing space on the grafting direction.
Summary of the invention
The object of the present invention is to provide jack contact that is used for narrow and small installing space and electric connector that a kind of cable connects does not influence the grafting size.
The technical scheme of electric connector of the present invention is: a kind of electric connector; Comprise insulator and jack contact wherein; It is characterized in that: said jack contact comprises reducing sleeve and is located at the jack that being used in the reducing sleeve cooperates with contact pin, said reducing sleeve be by the sleeve that is provided with jack with from the outer peripheral face of sleeve along jack radially the extended wiring handle that is used for being connected of one with cable constitute.
Said wiring handle is the line ball tube with centre bore.
Said jack is the female part of inserting in the sleeve of reducing sleeve, and said sleeve has centre bore confession female part inserting and both are through being tightly fixed.
Said insulator is to be fastened by a pair of insulation shell to form, and fixes through nut and screw.
One stomidium mouth of said female part is to be used to guarantee the contact of corresponding contact pin when the inserting structure that closes up reliably.
The hole wall at said closing in structure place is divided into many lobes by many axial straight joints and draws in to the center.
The technical scheme of jack contact of the present invention is: a kind of jack contact; Comprise reducing sleeve and be located at the jack that being used in the reducing sleeve cooperates with contact pin, said reducing sleeve be by the sleeve that is provided with jack with from the outer peripheral face of sleeve along jack radially the extended wiring handle that is used for being connected of one with cable constitute.
Said wiring handle is the line ball tube with centre bore.
Said jack is the female part of inserting in the sleeve of reducing sleeve, and said sleeve has centre bore confession female part inserting and both are through being tightly fixed.
Said insulator is to be fastened by a pair of insulation shell to form, and fixes through nut and screw.
One stomidium mouth of said female part is to be used to guarantee the contact of corresponding contact pin when the inserting structure that closes up reliably.
The hole wall at said closing in structure place is divided into many lobes by many axial straight joints and draws in to the center.
The sleeve outer peripheral face upper edge jack of jack contact of the present invention radially extends the wiring handle; Cable through the wiring handle connects contact has been avoided interfering with the axial alternation sum of jack; Terminals do not have axial dimension fully, thereby make the axial dimension of jack can all be used for the size of adaptive corresponding contact pin, and do not increase extra axial terminals size; Thereby make jack contact of the present invention effectively utilize installing space, realized the linkage function of the product that the grafting director space is narrow and small.
In addition; The present invention is the microminiaturized product that is adapted at using in the small space, and is different according to the function of reducing sleeve and jack, and the jack of jack contact of the present invention and reducing sleeve are for dividing body component; The reducing sleeve of jack contact mainly plays the effect of protection jack and connection cable; And jack is mainly used in contact pin and contacts, and divides body structure to be convenient on female part, process with contact pin and cooperates reliable contact structure, also be convenient to reducing sleeve to the female part real-time guard with fixing.

Embodiment
Like Fig. 1～shown in Figure 4, electric connector socket of the present invention comprises insulator 4 and jack contact wherein, and insulator 4 is to be fastened by a pair of insulation shell to form, and fixes through nut 1 and screw 2.Said jack contact comprises the female part 8 of inserting in reducing sleeve 7 and the reducing sleeve 7, reducing sleeve 7 be by the sleeve 7-1 with centre bore and from the outer peripheral face of sleeve 7-1 along sleeve radially the extended line ball tube 7-2 of one constitute.The centre bore of sleeve 7-1 supplies the jack contact inserting and both are through being tightly fixed.One stomidium mouth of said female part 8 is to be used to guarantee the contact of corresponding contact pin when the inserting structure 8-1 that closes up reliably, and the hole wall at said closing in structure 8-1 place is divided into many lobes by many axial straight joints 9 and draws in to the center, makes contact reliable.
Socket of the present invention is when reality is used; Jack contact is fixed in the insulator 4; Grafting shielded conductor 6 among the line ball tube 7-2 on the jack contact, insulator 4 afterbodys firmly are fixed together shielded conductor 6 and insulator 4 through heat-shrink tube 5 pyrocondensations, and the line ball tube 7-2 and the shielded conductor 6 that extend along the vertical direction of grafting direction adopt the crimping form; Saved the space, operative weldability is strong simultaneously.
Embodiments of the invention be applied to the installing space of socket limited, require socket (can not surpass 6mm in that the size that plugs together direction is minimum; And the user locates the actual effective length 3mm of electrode) occasion; As shown in Figure 3; Electrode panel 11 is provided with the electrode contact pin 12 that stretches out from its surface, other be provided with electrode panel 11 on 12 of electrode contact pins stretch out surperficial parallel corresponding cover plate 13, the spacing between cover plate 13 and the electrode panel 11 minimum (6mm); The actual effective length that electrode contact pin 12 stretches out electrode panel 11 surfaces is very short (3mm), and socket shown in dotted lines in Figure 3 is installed between electrode panel 11 and the cover plate 13.
Jack in the foregoing description and reducing sleeve are for dividing body structure, and jack also can directly be opened in the sleeve of reducing sleeve certainly; And the line ball tube also can adopt the wiring pommel replacement of other common structures, such as solid binding post with the welding manner welding lead.
