Protecting effect is good, and does not influence lead accumulator to use process.
A kind of lead accumulator with terminal protective cover, including cell body, groove lid and the binding post in groove lid,
The top surface of the groove lid has boss, and boss, which is provided with cover plate groove, the cover plate groove, is provided with fluid injection hole post, the boss side surfaces
With the depression for avoiding binding post, the free end of the binding post is extended beyond above groove lid edge, the binding post
Protection cap provided with square, the horizontal side plate of protection cap coordinates with the depression, and flush and be connected with boss, and protection cap is erected
Straight flange plate is connected by bolt with cell body or groove lid, and medial surface reclines the free end of binding post.Protection cap is from above and sideways
Positive and negative binding post is protected, makes positive and negative binding post be difficult to touch, as long as and connecting wire is from the two of protection cap when using
Side is connected respectively, it is not necessary to open protection cap, easy to use, and lead accumulator integral surface is smooth, keeps attractive in appearance same
When, it is again convenient to stack, it is easy to deposit and transports.
Cover plate support is provided with the cover plate groove.Cover plate support plays a part of supporting and fixed cover plate, passes through when fixed
Gluing is adhesively fixed.
The cell body has lug in the one end for installing binding post, and lug cooperatively forms connecting portion, the company with groove lid
There is the embedded nut coordinated with bolt in socket part.The main purpose that lug is set is to place embedded nut, the upper table of lug
The middle part in face is recessed, corresponding groove lid relevant position fovea superior, and both cooperatively form the slotted eye of fixed embedded nut.
The binding post is divided into the step for being provided with and coordinating with groove lid edge between two sections, two sections.
The binding post is connected with connecting portion by connecting rod.So both binding post is securely fixed with connecting portion, together
When cell body also securely fixed in connecting portion with groove lid, and one end that connecting rod is contacted with connecting portion can be by being hidden in connecting portion
The mode such as portion or selection non-conducting material avoids too exposing outside and producing potential safety hazard.
The connecting portion top surface has the protection platform of support binding post.
The free end of the binding post is provided with the connecting hole of center line level.The connecting hole is used to connect wire, is certainly
Convenient use, can pass through the connecting hole, then wire is wrapped in one end of bolt with bolt, then is tightened and leads with nut
Line.
The side of the depression has the support column coordinated with horizontal side plate.Support for supporting protection cap, simultaneously
Ensure that the horizontal side plate of protection cap is flushed with boss to be connected.
The inner side of the protection cap is provided with the block piece for separating two binding posts.Typically under the protection of protection cap,
Conductive materials are not had between two binding posts and are dropped and cause the risk of short circuit, can be with but for the sake of further safety
Two binding posts are separated with block piece, so as to ensure enough safety.
Binding post is arranged in the depression of groove lid side by lead accumulator of the present invention, is then protected with protection cap, it is to avoid
Because conductive body imprudence touches positive and negative binding post during the storage, transhipment and use of lead accumulator, cause short
Road.It is easy to use as long as and connecting wire is connected respectively from the both sides of protection cap when using, it is not necessary to open protection cap,
It is again convenient to stack while keeping attractive in appearance and lead accumulator integral surface is smooth, it is easy to deposit and transports.
