Abstract

The utility model discloses a joint combination, comprising a male joint and a female joint. The male joint is provided with a first insulating base and a first conduction element arranged on the first insulating base. The female joint is provided with a second insulating base which can be jointed with the first insulating base and a second conduction element which can be connected with the first conduction element. Wherein, the first base is formed with a joint face which is provided with an external thread part. The second base is correspondingly formed with an annular wall which can be inserted with the joint face of the first base. In addition, the inner face of the annular wall is provided with an internal thread part for jointing the external thread in screw joint. Therefore, the jointing strength of the first base and the second base and the water-proof seal after jointing are increased.

Description

Splice combinations

Technical field

The utility model relates to a kind of splice combinations, is meant the splice combinations that is applied to the connecting line in DC power supply connection or the source of sound connection especially.

Background technology

In the connection of general DC power supply, being connected between the body of rectifier and connecting line for example, perhaps rectifier connects between line end joint and the galvanic electronic installation of use not, major part is the joint that utilizes the mode of injection molding can dock mutually in each self-forming one of two links, a common end is male joint, and being the mode of female joint, the other end interconnects, but as above-mentioned splice combinations, major part still adopts mutual grafting and utilizes each other the mode of frictional force to locate mutually, make connecting line one be subjected to pullling promptly and come off slightly, cause to use and go up suitable inconvenience.

Having a kind of in addition is to be provided with corresponding coupler construction in male joint and female joint, though it has the effect than strong resistance torsion, but the tension effect that is reached is limited, the effect that increases is also little, and no matter whether have coupler construction, therefore adaptation after above-mentioned male joint and the combination of female joint are all considered to engage makes the infiltration of moisture or aqueous vapor easily, and it is very big to influence the signal transmission quality.

The utility model content

Main purpose of the present utility model is, provide a kind of have bond strength higher and engage after the also good splice combinations of waterproof adaptation.

For realizing above-mentioned purpose, a kind of splice combinations that the utility model provides, comprise a male joint and a female joint, this male joint has one first insulating base frame and and is positioned at first conducting element on this first insulating base frame, this female joint then has one and can it is characterized in that for second conducting element of this first conducting element electric connection for second insulating base frame and that this first insulating base frame engages:

This first insulating base frame is formed with a composition surface, be equipped with an external thread part on this composition surface, this second insulating base frame then is formed with one accordingly and supplies the annular leg of the composition surface insertion of this first insulating base frame, makes the inner face of this annular leg be provided with the internal thread part that supplies this external thread part screw engagement.

Advantage of the present utility model is: the bond strength that increases this first insulating base frame and this second insulating base frame thus with engage after the waterproof adaptation, make the intensity of splice combinations and waterproof adaptation better.

Description of drawings

Fig. 2 is a partly cross-sectional schematic of this preferred embodiment side.

Embodiment

Consult Fig. 1 and Fig. 2, a preferred embodiment of splice combinations of the present utility model is to comprise a male joint 1 and a female joint 2.

This male joint 1 has one first insulating base frame 11 and one first conducting element 12, on making, first conducting element 12 links to each other with the end of a connecting line 3 earlier, make insulating material partly be coated on the end of first conducting element 12 and connecting line 3 and form first insulating base frame 11 again, make the conducting element 12 of winning protrude from the front end place of first insulating base frame 11 in the mode of ejection formation.And the utility model more is formed with a composition surface 111 on first insulating base frame 11, is equipped with an external thread part 13 on this composition surface 111.

2 of this female joints have one second insulating base frame 21 and connect second conducting element 22 of a connecting line 4, its production method and male joint 1 are similar, but second conducting element 22 is to be positioned at second insulating base frame 21, and second insulating base frame 21 is formed with the annular leg 211 that insert on the composition surface 111 of a confession first insulating base frame 11 accordingly, makes the inner face of annular leg 211 be provided with the internal thread part 23 that supplies adjacent 13 screw engagement of external screw thread.

During combination, in the opening that the annular leg 211 that makes first conducting element 12 of first insulating base frame, 11 front ends insert second insulating base frame 21 is surrounded, when annular leg 211 EDGE CONTACT of the composition surface 111 of first insulating base frame 11 and second insulating base frame 21, can on the grafting direction, form interference because of the internal thread part 23 of the external thread part 13 of first insulating base frame 11 and the annular leg 211 of second insulating base frame 21 and can't continue insertion, first insulating base frame 11 is rotated with respect to second insulating base frame 21, and make the external thread part 13 of first insulating base frame 11 and the internal thread part 23 of second insulating base frame 21 further screw togather and interconnect in the mode of being spirally connected, by the be spirally connected characteristic of external thread part 13 with internal thread part 23, can increase the bond strength of first insulating base frame 11 and second insulating base frame 21, and the adaptation after screwing togather is also better, can reach better water proofing property.

Though and above stated specification is that respectively to be connected a connecting line 3 or 4 with male joint 1 and female joint 2 be example, but whether have the knack of this technology when can thinking and splice combinations directly is applied on the circuit board and the application mode that does not engage with connecting line, therefore being connected with connecting line formation is not restrictive condition of the present utility model surely.In addition, the utility model uses except the connection as DC power supply, and the transmission that also can be used as general signal is certainly used, and perhaps uses as the transmission of source of sound signal.

Claims (1)

1, a kind of splice combinations, comprise a male joint and a female joint, this male joint has one first insulating base frame and and is positioned at first conducting element on this first insulating base frame, this female joint then has one and can it is characterized in that for second conducting element of this first conducting element electric connection for second insulating base frame and that this first insulating base frame engages:

This first insulating base frame is formed with a composition surface, be equipped with an external thread part on this composition surface, this second insulating base frame then is formed with one accordingly and supplies the annular leg of the composition surface insertion of this first insulating base frame, makes the inner face of this annular leg be provided with the internal thread part that supplies this external thread part screw engagement.
