Abstract

A connection structure includes a male connector, a female connector including a first clamping portion and a through hole for inserting the male connector, a marking member including a second clamping portion configured to be clamped with the first clamping portion, and a locking member installed on the female connector. The locking member is configured to move from a first position to a second position when an insertion depth of the male connector reaches a preset value, so as to lock the male connector and drive the second clamping portion to separate from the first clamping portion.

First claim

What is claimed is:

1. A connection structure, comprising:
a male connector;
a female connector, comprising a first clamping portion and a through hole for inserting the male connector;
a marking member, comprising a second clamping portion, wherein the second clamping portion is configured to be clamped with the first clamping portion; and
a locking member, installed on the female connector, wherein the locking member is configured to move from a first position to a second position when the male connector is inserted into the through hole of the female connector, so as to lock the male connector and drive the second clamping portion to separate from the first clamping portion;
wherein a peripheral surface of the male connector is provided with an annular groove, the locking member comprises a clamping platform and two connecting arms arranged below the clamping platform, the two connecting arms are provided at intervals below the clamping platform, and the clamping platform is configured to be inserted into the annular groove when the locking member is in the second position.

2. The connection structure according to claim 1 , wherein the first clamping portion is configured as a clamping groove provided on a peripheral side of the female connector, and the second clamping portion is configured as a clamping hook provided on the marking member.

3. The connection structure according to claim 2 , wherein:
the clamping groove is one of two clamping grooves arranged at intervals on the peripheral side of the female connector; and
the clamping hook is one of two clamping hooks configured to be clamped with the two clamping grooves, respectively.

4. The connection structure according to claim 1 , wherein the locking member is provided with a clamping groove, the marking member is provided with a clamping hook, and the clamping hook is configured to be clamped with the clamping groove, wherein the locking member is configured to, when the locking member moves from the first position to the second position, drive the clamping hook to separate from the clamping groove.

5. The connection structure according to claim 4 , wherein:
the clamping groove is one of two clamping grooves correspondingly provided on two sides of the locking member; and
the clamping hook is one of two clamping hooks configured to be clamped with the two clamping grooves, respectively.

6. The connection structure according to claim 5 , wherein the two clamping grooves are formed between the two connecting arms and the clamping platform.

7. The connection structure according to claim 1 , wherein one side of each of the two connecting arms away from the through hole is provided with a groove, which is configured to be abutted against the female connector when the male connector is inserted into the through hole.

8. The connection structure according to claim 1 , wherein a peripheral side of the female connector is provided with a clamping groove, the locking member is further provided with a clamping hook, and the clamping hook is configured to be inserted into the clamping groove when the locking member is in the first position.

9. The connection structure according to claim 8 , wherein:
the clamping groove is one of two clamping grooves provided at intervals on the peripheral side of the female connector; and
the clamping hook is one of two clamping hooks provided at respective ends of the two connecting arms away from the clamping platform.

10. The connection structure according to claim 1 , wherein one side of the locking member facing the through hole is provided with a limit groove, and an edge of the through hole is provided with a limit block corresponding to the limit groove, wherein the limit block is configured to be inserted into the limit groove when the locking member is in the second position.

11. The connection structure according to claim 1 , wherein the marking member is provided with a pulling portion, which is configured for a user to remove the marking member from the locking member.

12. The connection structure according to claim 1 , wherein the marking member is provided with an installation gap, which is configured to accommodate a part of the locking member.

13. The connection structure according to claim 1 , wherein one side of the marking member facing the locking member is provided with a positioning column, and one side of the locking member facing the marking member is provided with a positioning hole, wherein the positioning column is configured to be inserted into the positioning hole to connect the locking member and the marking member.

14. A battery, comprising the connection structure according to claim 1 , wherein the connection structure is configured to connect cooling pipelines of a cooling system of the battery.

15. A power consumption device, comprising the battery according to claim 14 , wherein the battery is configured to provide electrical energy.

16. A connection structure, comprising:
a male connector;
a female connector, comprising a first clamping portion and a through hole for inserting the male connector;
a marking member, comprising a second clamping portion, wherein the second clamping portion is configured to be clamped with the first clamping portion; and
a locking member, installed on the female connector, wherein the locking member is configured to move from a first position to a second position when the male connector is inserted into the through hole of the female connector, so as to lock the male connector and drive the second clamping portion to separate from the first clamping portion;
wherein the locking member is provided with a clamping groove, the marking member is provided with a clamping hook, the clamping hook is configured to be clamped with the clamping groove, and the locking member is configured to, when the locking member moves from the first position to the second position, drive the clamping hook to separate from the clamping groove.

17. A connection structure, comprising:
a male connector;
a female connector, comprising a first clamping portion and a through hole for inserting the male connector;
a marking member, comprising a second clamping portion, wherein the second clamping portion is configured to be clamped with the first clamping portion; and
a locking member, installed on the female connector, wherein the locking member is configured to move from a first position to a second position when the male connector is inserted into the through hole of the female connector, so as to lock the male connector and drive the second clamping portion to separate from the first clamping portion;
wherein one side of the marking member facing the locking member is provided with a positioning column, one side of the locking member facing the marking member is provided with a positioning hole, and the positioning column is configured to be inserted into the positioning hole to connect the locking member and the marking member.
