Connection head module

Abstract

A connector module includes a housing, a first connector, a delivery pipe, a second connector, and a seal. The housing has a first through-hole. The first connector includes an annular portion and a tubular portion. The annular portion is located inside the housing and abuts against the housing. The tubular portion connects to the annular portion and passes through the first through-hole. The delivery pipe includes a connecting portion and at least one sub-delivery pipe. The sub-delivery pipe connects to the connecting portion. The connecting portion abuts against the annular portion and includes a space communicating between the tubular portion and the sub-delivery pipe. The second connector connects to the tubular portion. The seal is located outside the housing and includes a fixing portion, an elastic portion, and a collar. The elastic portion connects between the fixing portion and the collar. The fixing portion connects to the housing. The collar is fitted onto the tubular portion. The elastic portion and the tubular portion are at least partially spaced apart from each other.

Claims

1. A connector module, comprising: a housing having a first through hole; a first connector including an annular portion and a tubular portion, the annular portion being located inside the housing and abutting against the housing, the tubular portion being connected to the annular portion and passing through the first through hole; a delivery pipe including a connecting portion and at least one sub-delivery pipe, the sub-delivery pipe being connected to the connecting portion, the connecting portion abutting against the annular portion and including a space communicating between the tubular portion and the sub-delivery pipe; a second connector connecting the tubular portion; and a sealing member located outside the housing and including a fixing portion, an elastic portion and a sleeve, the elastic portion being connected between the fixing portion and the sleeve, the fixing portion being connected to the housing, the sleeve being fitted onto the tubular portion, the elastic portion and the tubular portion being at least partially spaced apart from each other.

2. The connector module as described in claim 1, wherein the elastic part comprises: a plurality of elastic rings folded and connected to each other.

3. The connector module as described in claim 2, wherein, of the two adjacent elastic rings, the one closer to the fixing part is larger than the one closer to the collar.

4. The connector module as described in claim 1, wherein one of the external dimensions of the elastic portion tapers toward the collar.

5. The connector module as claimed in claim 1, wherein the tube includes a groove surrounding one of the outer surfaces of the tube, and the collar is at least partially embedded in the groove.

6. The connector module as claimed in claim 1, wherein the housing further includes a plurality of second through holes, the second through holes at least partially surrounding the first through hole, and the seal further includes: a plurality of locking portions disposed on the side of the fixing portion away from the elastic portion, each of the locking portions including: a conical head configured to abut against the housing; and a column connecting the fixing portion and the conical head and passing through a corresponding one of the second through holes.

7. The connector module as described in claim 6, wherein the locking portions at least partially surround the annular portion.

8. The connector module as described in claim 1 further comprises: an adhesive layer adhered between the fixing part and the housing.

9. The connector module as described in claim 1, wherein the second connector is at least partially inserted into the tube.

10. The connector module as claimed in claim 1 further comprises: a guide sleeve for connecting the second connector, wherein one end of the second connector remote from the first connector is located within the guide sleeve.
