Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

As shown in Figure 1, the utility model provides a kind of combined electric connector, including plug 1 and socket 2,1 He of plug 2 snapping of socket, plug 1 include plug body 101, and 101 threaded one end of plug body is connected with plug shell cover 3, and is set in shell cover 3 There is threading hole 4, live wire guard ring 9 is installed in threading hole 4, plug body 101, which is equipped with, holds wire casing 7, holds 7 peripheral hardware live conductor of wire casing Plate 8.

In present embodiment, plug 1 and socket 2 are grouped together into an electric connector, and plug shell cover 3 will be in plug Circuit be isolated with external environment, prevent circuit from being damaged to external staff, the electric wire guard ring 9 being arranged on threading hole 4 rises The effect of protection conducting wire is arrived, it is therefore prevented that conducting wire damages during shaking with the friction of plug shell cover 3, holds wire casing 7 and pressure The setting of line plate 8, it is therefore prevented that conducting wire falls off from plug 1 when relative displacement occurring between conducting wire and plug 1, and conducting wire is prevented respectively Only in different appearance wire casings 7, then conducting wire is fixed on by tension disc 8 and is held in wire casing 7, conductor separation is placed, and is also avoided The short circuit risk that conductor insulation sheath breakage is brought.

First insulation board 102 is installed in plug body 101, termination 5, wiring are embedded on the first insulation board 102 Device 5 includes wiring cylinder 501 and contact pin 502, and spherical wire pressing block 503,503 peripheral hardware of spherical wire pressing block are socketed on wiring cylinder 501 There are wiring cylinder 504,502 one end of contact pin that the lock sleeve 505 to match with wiring cylinder 501 is installed, 502 other end of contact pin is equipped with Lock 506,502 one end of contact pin is plugged in wiring cylinder 501.

In present embodiment, the first insulation board 102 opens conductor separation, it is therefore prevented that short circuit danger occurs for contact between conducting wire Danger, the specific method that plug 1 is connect with outer lead are：Outer lead is inserted into wiring cylinder 504 first, then by contact pin One end with lock sleeve 505 is inserted into wiring cylinder 501 on 502, with deepening continuously for contact pin 502, spherical wire pressing block 503 It is pushed into wiring cylinder 504, final conducting wire is fixed on by spherical wire pressing block 503 in wiring cylinder 504, is finally placed into conducting wire Hold in wire casing 7, fix tension disc 8, installation method is simple and fast, and connection is firm, avoids in connection procedure and generates Poor contact and breaking phenomena generation.

Socket 2 includes jack housing 201, is threaded with socket shell cover 6 in jack housing 201, and in socket shell cover 6 It equipped with threading hole 4, is equipped in jack housing and holds wire casing 7, and held wire casing 7 and be externally provided with tension disc 8, be equipped in jack housing 201 Second insulation board 202 is embedded with connecting pole 203 on second insulation board 202, and 203 one end of connecting pole is socketed on contact pin 502, even It connects 203 other end of column and is socketed with crimp type terminal.

In present embodiment, it is provided with the groove to match with lock 506 in connecting pole 203, holds wire casing 7 and tension disc 8 Setting, it is therefore prevented that outer lead falls off from socket 2 and causes electrical contact bad or breaking, and socket 2 connects with outer lead Connecing need to only be inserted into external conducting wire in crimp type terminal 10, and outer lead is then crimped on crimp type terminal 10 using Press Plier It is interior, after plug 1 and socket 2 are connect with outer lead, contact pin 502 is directed at connecting pole 203, plug 1 and socket 2 are buckled It is connected together, after 2 snapping of plug 1 and socket, lock 506 is buckled in groove so that it is firm that plug 1 and socket 2 connect.
