In the embodiment of the application, after the socket 2 is fixed on the outer side of the battery stack 1, the socket 3 is matched and fixed with the socket 2, so that the socket 3 is prevented from falling off from the socket 2; then with connecting terminal 4 insert behind the socket 3 with 1 cooperations of pile, at this moment, connecting terminal 4's one end can block firmly in socket 3 and can not drop, and the other end stretches out socket 3 outward, the staff of being convenient for plug pencil 5.

Referring to fig. 2 to 3, in the present embodiment, a plurality of separators 31 are disposed at one end of the socket 3 near the cell stack 1; a mounting gap 33 is formed between two adjacent partition plates 31; one end of the socket 3, which is far away from the battery pile 1, is provided with a plurality of clamping grooves 32; a stepped groove 34 is provided in the mounting gap 33 communicating with the detent groove 32.

The width of the stepped groove 34 is greater than the width of the detent groove 32. When the connection terminal 4 is compressed, the connection terminal 4 can be inserted into the stepped groove 34 from the detent groove 32, and since the width of the stepped groove 34 is greater than the width of the detent groove 32, the compressed connection terminal 4 can be spread in the stepped groove 34; at this time, the connection terminal 4 can be firmly abutted in the stepped recess 34 without falling off.

Referring to fig. 3 and 5, in the embodiment of the present application, the top of the socket 3 is provided with an elastic protrusion 35; the socket 2 is provided with an inner recess 21 matched with the elastic bulge 35.

The pluggable connector has five groups of connecting terminals 4, and is divided into two lines which are arranged in a staggered mode in sequence. Because the quantity of monocells that powerful battery pile contains is more, and is different from dozens of monocells to several hundreds of monocells, consequently, in order to reduce the number of patrolling and examining, increases the fault-tolerant rate, also for the convenience of the design of connecting terminal simultaneously, can increase the size design of connector, in this embodiment, every two monocells 11 detect for a set of, make an interval monocell 11 between every two connecting terminal 4 not be connected with connecting terminal 4. Wherein each connection terminal 4 is used only for collecting voltage data of the connected cells 11. In practical applications, a plurality of pluggable connectors can be used simultaneously.

The pluggable connector can be used for the whole service life cycle of the fuel cell stack, and is small in limitation and high in practicability.

According to the pluggable connector with the secondary anti-falling function, the elastic bulge 35 at the top of the jack 3 is matched with the inner recess 21 on the socket 2, so that the jack 3 can be stably installed on the socket 2, and falling (primary anti-falling) caused by vibration is avoided. Through inserting connection terminal 4 screens recess 32 under the state of compressed, reach step recess 34 after can stabilize the butt in step recess 34 owing to the elasticity effect of self expands after reseing, prevented effectively that connection terminal 4 from coming off (secondary anticreep) from the socket to avoided connection terminal 4 to produce the condition of contact failure because of the operating mode condition vibrations, guaranteed the stability of the pile voltage data of collection. Each part can separately cooperate in the application, so that the plugging operation is convenient, and the operation is very humanized. Compare in the mode of conventional surface contact collection voltage, this application structure is simpler, the installation is more convenient, and is more reliable stable in the use, can realize the purpose of accurate monitoring voltage.
