Abstract
The utility model discloses a kind of electric connector, comprise electric connector main body (A) and hood (B); Hood (B) comprise connecting ring (1), O type rubber ring (2), cable hood (5), briquetting (6), sealing ring (7) and and tight ring (3); Hood (B) also comprises elastic ring (4); O type rubber ring (2) is put into the seal groove of connecting ring (1), reinstall elastic ring (4), the outer wall of elastic ring (4) and the inwall close contact of connecting ring (1) is made by the elastic dilatation of elastic ring (4), elastic ring (4) forms a space closed for the three side sealing of accommodate O-shaped rubber ring (2) with the seal groove of connecting ring (1) simultaneously, prevents O type rubber ring (2) from deviating from seal groove when connector body (A) is connected with hood (B).The utility model can prevent rubber ring from coming off, and reduces assembling and difficulty of processing, improves the useful life of electric connector.
Description
Technical field
The utility model relates to a kind of electric connector.
Background technology
As shown in Figure 1, existing waterproof type connector comprises electric connector main body A and hood B.When connector body A is screwed into hood B, after 0 type rubber ring 2 contacts with the housing 8 in connector body A, rubber ring 2 can rotate in the face of its frictional force produced by housing 8 end of thread, can be squeezed and be compressed simultaneously.Now, rubber ring 2 easily distortion, thus depart from seal groove, cause overall structure to lose waterproof effect.Even if adopt the mode of gluing adhesive rubber circle, after a number of uses, also there will be the phenomenon that rubber ring departs from rubber groove, have a strong impact on the serviceability of product.For this reason, a kind of effective measures need be taked to come off to prevent rubber ring 2.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of electric connector preventing rubber ring from coming off, and can reduce assembling and difficulty of processing, improves the useful life of electric connector.
The technical solution of the utility model is:
A kind of electric connector, comprises electric connector main body and hood; Electric connector main body comprises housing, hood comprise connecting ring, type rubber ring, cable hood, briquetting, sealing ring and and tight ring; It is characterized in that: hood B comprises elastic ring; Type rubber ring is put into the seal groove of connecting ring, reinstall elastic ring, the outer wall of elastic ring and the inwall close contact of connecting ring is made by the elastic dilatation of elastic ring, the seal groove of elastic ring and connecting ring forms a space closed for the three side sealing holding type rubber ring simultaneously, prevents type rubber ring from deviating from seal groove when connector body is connected with hood; Then will also tight ring, sealing ring, briquetting put into cable hood successively, then connecting ring will be screwed into cable hood, thus compresses seal.
The beveled end of elastic ring (4) and the inclined-plane of connecting ring inwall are close to, and elastic ring planar ends is lower than an end face 0.2-0.4mm of rubber ring (2) simultaneously.
The length of 0 type rubber ring is 1.6-1.8mm, and the length that elastic ring contacts with 0 type rubber ring is 1.4-1.6mm, and the length of the contact internal walls of elastic ring and connecting ring (1) is 3.2mm.
The utility model compared with prior art beneficial effect is: increase elastic ring on existing structure after, elastic ring fits tightly on connecting ring inwall because of elastic dilatation, form the seal groove that a complete three side sealing closes, rubber ring is arranged in this groove, the phenomenon that can effectively prevent rubber ring from coming off occurs, the practicality of product, reliability are strengthened, improves the useful life of electric connector; In addition, elastic ring is adopted can to reduce assembling and difficulty of processing.
Accompanying drawing explanation
Fig. 1 is existing electric connector two-dimensional representation;
Fig. 2 is the electric connector hood two-dimensional representation after the utility model improves.
Fig. 3 is that the three side sealing that elastic ring and connecting ring are connected to form closes structural representation.
Embodiment
As shown in Figure 2, electric connector of the present utility model, comprises electric connector main body A and hood B; Electric connector main body A comprises housing 8, hood B comprise connecting ring 1,0 type rubber ring 2, cable hood 5, briquetting 6, sealing ring 7 and and tight ring 3; Connector body A is connected when coordinating with hood B, the housing 8 in connector body A compresses 0 type rubber ring 2 in hood B, makes junction reach sealed waterproof effect; Hood B also comprises elastic ring 4; 0 type rubber ring 2 is put into the seal groove of connecting ring 1, reinstall elastic ring 4, the outer wall of elastic ring 4 and the inwall close contact of connecting ring 1 is made by the elastic dilatation of elastic ring 4, elastic ring 4 forms a space closed for the three side sealing holding 0 type rubber ring 2 with the seal groove of connecting ring 1 simultaneously, prevents 0 type rubber ring 2 from deviating from seal groove when connector body A is connected with hood B; Then will also tight ring 3, sealing ring 7, briquetting 6 put into cable hood 5 successively, then connecting ring 1 will be screwed into cable hood 5, thus compresses seal 7.
During assembling, only need carry out compression to elastic ring 4 and just can assemble easily: elastic ring 4 beveled end and connecting ring 1 inwall inclined-plane are close to, elastic ring 4 planar ends should lower than an end face of rubber ring 2 simultaneously.Preferably, lower than 0.2-0.4mm.
Preferably, the length of 0 type rubber ring 2 is 1.6-1.8mm, and the length that elastic ring 4 contacts with 0 type rubber ring is 1.4-1.6mm, and elastic ring 4 is 3.2mm with the length of the contact internal walls of connecting ring 1, to ensure to contact compactness, such that rubber ring is more difficult to come off.
Principle of the present utility model is, the structure of existing seal groove only has two face closures, rubber ring 2 easy distortion and deviate from seal groove in loading process.As shown in Figure 2, after existing structure increases elastic ring 4, elastic ring 4 fits tightly by compression on connecting ring 1 inwall, forms rubber ring 2 groove that a complete three side sealing closes, rubber ring 2 is arranged in this groove, and the phenomenon that can effectively prevent rubber ring 2 from coming off occurs.
The content be not described in detail in the utility model specification belongs to the known technology of those skilled in the art.
