Electric connector

【Technical field】

The utility model is in relation to a kind of electric connector, espespecially a kind of electric connector for forward and reverse insertion.

【Background technology】

In the prior art, the waterproof between electric connector and casing is usually that a ring is arranged outside the shell of electric connector The rubber ring of shape realizes the sealing waterproof between the shell of electric connector and casing with this.However, traditional rubber ring is only capable of Ensure that the rudimentary waterproof between the shell and casing of electric connector, the continuous improvement with people to waterproof requirement utilize tradition Rubber ring realizes that the mode of waterproof cannot be satisfied the demand of people.

Therefore, it is necessory to be improved to existing electric connector, to overcome drawbacks described above.

【Utility model content】

The purpose of this utility model is to provide a kind of electric connectors being molded water proof ring with liquid-state silicon gel, and silica gel is not The outside wall surface of shell can be spilled over to.

The purpose of this utility model is achieved through the following technical solutions：A kind of electric connector, including insulating body, fixing Several conducting terminals in the insulating body and the shell that is coated on outside the insulating body, the outer wall of the front end of the shell Recessed be formed in face is molded for liquid-state silicon gel to form the storage tank of water proof ring, and the rear wall of the storage tank has protruded out gear forward Only the liquid-state silicon gel is spilled over to the convex block in the outside wall surface of the shell upwards.

Further, the insulating body includes the pedestal being immobilizated in the shell and from pedestal projection shape forward At between the shell constitute butt cavity hyoplastron.

Further, the conducting terminal includes the holding parts being immobilizated in the pedestal, prolongs forward from the holding parts The weld part that stretches be exposed to the contact site on the surface of the hyoplastron and extend back from the holding parts.

Further, the top surface of the convex block is flushed with the outside wall surface of the shell.

Further, the top surface of the convex block is less than the outside wall surface of the shell.

Further, the top surface of the convex block is connected to formation with the storage tank and is overflowed into for liquid-state silicon gel in the longitudinal direction Excessive glue groove.

Further, the storage tank is the annular groove for the outside wall surface for being located on the shell, and the convex block is located on institute The rear surface for stating storage tank forms annular lug.

Further, the water proof ring have the main part concordant with the outside wall surface of the shell and from the main part to The protruding portion that upper projection is formed.

Further, the main part, which is equipped with, is located at the notch that the underbump coordinates with it.

Further, the shell includes the metal shell being coated on outside the insulating body and is coated on the metal-back External plastic casing, the storage tank are set to the outside wall surface of the plastic casing.

Compared with prior art, the utility model has the advantages that：It is convex forward by the rear wall in storage tank Stretch to form convex block, can liquid-state silicon gel described in block be spilled over to the outside wall surface of the shell upwards.

【Specific implementation mode】

Hereinafter, the specific implementation mode that the utility model electric connector will be introduced in conjunction with Fig. 1 to Fig. 4.

A kind of electric connector 100, including insulating body 1, several conducting terminals 2 being immobilizated in the insulating body 1, packet The shell 3 that is overlying on outside the insulating body 1, is set to 1 rear end of the insulating body at the water proof ring 4 being set to outside the shell 3 Splash guard 5 and be set to the shell 3 both sides jam plate element 6.

The insulating body 1 includes the pedestal 11 being immobilizated in the shell 3 and projection is formed forward from the pedestal 11 Between the shell 3 constitute butt cavity 30 hyoplastron 12.The conducting terminal 2 includes being immobilizated in consolidating in the pedestal 11 Hold portion 21, from the contact site 22 on the surface for being exposed to the hyoplastron 12 that the holding parts 21 extend forward and from the holding parts 21 extend back the weld part 23 of the pedestal 11.

In the utility model, the shell 3 preferably includes the metal shell 31 being coated on outside the insulating body 1 and packet The plastic casing 32 being overlying on outside the metal shell 31, the water proof ring 4 are set to outside the plastic casing 32, the jam plate member Part 6 is immobilizated in the both lateral sides of the plastic casing 32.The electric connector 100 is for being assembled to a casing (not shown), institute State water proof ring 4 be set to the outside wall surface 321 of the plastic casing 32 with realize electric connector 100 and the casing (not shown) it Between seal waterproof.The outside wall surface 321 of the front end of the plastic casing 32 is recessed to be formed with storage tank 322, and the storage tank is preferred Ground is annular groove, naturally it is also possible to be several spaced groove structures.The water proof ring 4 is that liquid-state silicon gel injects the appearance It sets in slot 322 and is formed after solidification.Excessive liquid-state silicon gel is injected into the storage tank 322 in order to prevent and leads to liquid-state silicon gel It is spilled over to backward in the outside wall surface 321 of the plastic casing 3, the rear surface 3221 of the storage tank 322 has protruded out forward block The liquid-state silicon gel is spilled over to the convex block 3222 in the outside wall surface 321 of the plastic casing 32 upwards.Equally, the convex block 3222 Preferably it is located on the annular lug of the rear surface 3221 of the storage tank 321.The water proof ring 4 has and the plastic casing The protruding portion 411 outside wall surface 321 of body 32 concordant main part 41 and formed from 41 upward projection of the main part, the protrusion It is reliably close between electric connector 100 and the casing (not shown) to realize that portion 411 presses on the casing (not shown) Seal waterproof.

Join shown in Fig. 2 and Fig. 3, is the utility model first embodiment, the top surface of the convex block 3222 and the plastic casing The outside wall surface 321 of body 32 flushes.Join shown in Fig. 4, be the utility model second embodiment, the top surface of the convex block 3222 ' is less than institute The outside wall surface 321 of plastic casing 32 is stated, the top surface of the convex block 3222 ' is connected to shape in the longitudinal direction with the storage tank 321 At the excessive glue groove 3223 overflowed into for liquid-state silicon gel.Compared to first embodiment, due to being formed with excessive glue groove on the top surface of convex block 3223, even if liquid-state silicon gel can preferentially overflow into the excessive glue groove 3223 if also overflowing, without flowing to plastic casing 32 Outside wall surface 321 on.In first, second embodiment, the main part 41, which is equipped with, is located at the convex block 3222,3222 ' The notch 412 that lower section coordinates with it.

Convex block 3222,3222 ' is arranged by the rear surface 3221 in storage tank 322 in the utility model electric connector 100, can Effective block liquid-state silicon gel is spilled over to when injecting excessive in the outside wall surface 321 of the plastic casing 32 backward.In addition, it is necessary to illustrate , the plastic casing 3 described in the utility model is not limited only to be made of plastic cement, can also be by metal powder metallurgy system At.The foregoing is merely some embodiments of the utility model, the embodiment being not all of, those of ordinary skill in the art Any equivalent variation taken technical solutions of the utility model by reading the utility model specification, is this practicality Novel claim is covered.
