Abstract
The utility model discloses a kind of combination hub that contact pin mounting hole and spliced eye can be isolated from the outside, including：Several contact pins and contact pin mounting base, the concrete structure of contact pin mounting base include：Bottom plate and the grafting body being arranged on bottom plate, it is offered in grafting body and the one-to-one spliced eye of the contact pin, it is offered on bottom plate and the one-to-one contact pin mounting hole of the spliced eye, the contact pin one-to-one corresponding is arranged in corresponding contact pin mounting hole, the back side of the bottom plate offers at least one sealing groove so that all contact pin mounting holes are respectively positioned in sealing groove.Combination hub described in the utility model can be widely used in the switching of various electric signals.
Description
Technical field
The utility model is related to arrive a kind of connector for electrical connection, and in particular to a kind of patching for electrical connection
Seat.
Background technology
At present, traditional combination hub, structure generally include：Several contact pins and contact pin mounting base, contact pin mounting base by
Bottom plate and the grafting body that is arranged on bottom plate are formed, offered in grafting body with the one-to-one spliced eye of the contact pin,
It offers on the bottom plate and is arranged on the one-to-one contact pin mounting hole of the spliced eye, contact pin one-to-one corresponding
It is pierced by the spliced eye of grafting body and from the contact pin mounting hole on bottom plate.Although contact pin mounting base is processed by mold, and
And be designed to be interference fitted by contact pin and contact pin mounting hole, but it is difficult to ensure that contact pin mounting hole and contact pin on its bottom plate
Between can accomplish to fit together perfectly, so allow for spliced eye and communicated by the gap between contact pin mounting hole and contact pin with the external world,
Contact pin is caused easily to be subject to be entered the corruption of the harmful substances such as water, acidity in spliced eye in use by contact pin mounting hole
Erosion, influences the electric conductivity of the contact pin, the combination hub is caused to be replaced due to loose contact, shorten service life, increases
Use cost.
Utility model content
Technical problem to be solved in the utility model is：There is provided one kind can be by contact pin mounting hole and spliced eye and the external world
The combination hub of isolation.
In order to solve the above technical problems, technical solution is used by the utility model：A kind of combination hub, including：It is several
A contact pin and contact pin mounting base, the concrete structure of contact pin mounting base include：Bottom plate and the grafting body being arranged on bottom plate, grafting body
In offer with the one-to-one spliced eye of the contact pin, offer and the one-to-one contact pin of the spliced eye on bottom plate
Mounting hole, contact pin one-to-one corresponding are arranged in corresponding contact pin mounting hole, and the back side of the bottom plate offers at least one
A sealing groove so that all contact pin mounting holes are respectively positioned in sealing groove.
As a preferred embodiment, in a kind of combination hub, the contact pin mounting hole is divided at least two arrangements
It puts on the bottom plate, offers the sealing groove for penetrating through each socket pin mounting hole on bottom plate respectively so that Mei Yipai
Contact pin mounting hole is respectively positioned in corresponding sealing groove.
As a preferred embodiment, in a kind of combination hub, installation base is provided on the back side of the bottom plate,
The contact pin mounting hole and sealing is opened in groove on the installation base.
As a preferred embodiment, in a kind of combination hub, at least two are provided on the back side of the bottom plate
Positioning column is installed.
As a preferred embodiment, in a kind of combination hub, described at least two installation positioning columns are arranged in
The both sides of the contact pin mounting hole.
As a preferred embodiment, in a kind of combination hub, the installation positioning column is arranged at the bottom plate back of the body
On the installation base in face.
The beneficial effects of the utility model are：The utility model on bottom plate by opening up sealing groove so that all
Contact pin mounting hole be respectively positioned in sealing groove, thus can by sealing with fluid sealant is perfused in groove so that insert
Pin mounting hole and spliced eye are isolated from the outside, and are entered so as to effectively prevent the harmful substances such as water or acidity by contact pin mounting hole
Contact pin is caused to corrode into spliced eye, so as to extend the service life of entire combination hub.Further, since it is set in contact pin bottom
Glue-line is put, thus while the leakproofness of the combination hub is ensured, it is ensured that the verticality of contact pin, insider is
Know, when the contact pin in plumbness more can guarantee that it is connected with external plug, keep good contact so that itself and grafting
The connection of head is more reliable and more stable.
