The utility model solves the problems of the technologies described above the technical scheme that is adopted: this cable branch joint, comprise insulation shell and be positioned at the metallic object of insulation shell cavity, first end that it is characterized in that described insulation shell is provided with a connectivity port, and second end of insulation shell is provided with two connectivity ports; Accordingly, described metallic object first end is provided with a joint, second end is provided with two joints, the port of insulation shell holds the joint of corresponding metallic object, described insulation shell comprises that first housing reaches and second housing of the first housing clamping, the described first housing side is provided with bayonet socket, and accordingly, the second housing side is provided with the card base of cooperation.

For increasing the sealing and the moisture-proof function of housing, described second housing closes on the card base place and is provided with annular groove, is with O-ring seal on this annular groove.

Described metallic object is " h " shape, and accordingly, the inner chamber of insulation shell also is " h " shape of cooperation.The shape of metallic object and the inner chamber of insulation shell can also other shapes, as " T " or " Y " etc.

Described card base is a rectangle in the orthographic projection of second housing, and the one side is vertical plane, and a side is and the inclined-plane of bayonet fittings that accordingly, described bayonet socket is a rectangle.Bayonet socket can also adopt arc or other shapes with the shape of the card base that is mated.

For satisfying the needs of cable " one-in-and-two-out ", a connectivity port on described insulation shell first end is the matrix port, and its inwall is provided with serrated slot, and two connectivity ports on second end are the formula port, and its outer wall is provided with serrated slot; Satisfy the needs of cable " two advance one goes out ", a connectivity port on described insulation shell first end is the formula port, and its outer wall is provided with serrated slot, and two connectivity ports on second end are the matrix port, and its inwall is provided with serrated slot.

Compared with prior art, advantage of the present utility model is: by pushing first housing towards second housing, realize assembling fast, shortened the production time greatly, saved human resources, cost reduces; Close on the card base place at second housing O-ring seal is set, increased the sealing and the fastness of insulation shell, also improved the moistureproof and waterproof function of joint simultaneously; The utility model overall structure is simple, compact, and fastness is good after installing, and associativity is good in the use.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1, and Fig. 1 to Fig. 6 constitutes present embodiment.

Referring to figs. 1 to Fig. 6, cable branch joint in the present embodiment, comprise insulation shell 4 and the metallic object 3 that is positioned at the insulation shell cavity, insulation shell 4 comprises that first housing 1 reaches and second housing 2 of its clamping, first housing, 1 side is provided with former and later two bayonet sockets 12, be provided with two card bases 23 before and after on second housing, 2 sides, card base is a rectangle in the orthographic projection of second housing, and its longitudinal cross-section is a right-angled trapezium, accordingly, the bayonet socket 12 of first housing 1 is a rectangle, card base 23 coincide with bayonet socket 12 size shape, and clamping is by pushing first housing 1 towards second housing 2, and card base 23 sticks into bayonet socket 12 and very fast realization, second housing 2 closes on card base 23 places and is provided with annular groove, is with O-ring seal 22 on this annular groove;
