Conducting wire sealing bent joint and preparation method thereof

Abstract

The invention provides a conducting wire sealing bent joint and a preparation method thereof. The conducting wire sealing bent joint comprises a bent pipe, an installing seat and a sealing conducting wire, wherein a position limiting table is arranged on the inner wall of each of two ends of the bent pipe; a through hole matched with the bent pipe is formed in the installing seat; the bent pipe passes through the through hole to be welded and fixed with the installing seat; a sieve plate is arranged on the position limiting table; a plurality of conducting wire through holes are formed in the sieve plate; the sealing conducting wire passes through the conducting wire through hole and the bent pipe; sealant is injected into the bent pipe for sealing; an installing hole is formed in the installing seat; a sealing position limiting groove is formed in the bottom end of the installing seat; a sealing pad is arranged in the sealing position limiting groove. The preparation method of the conducting wire sealing bent joint comprises the preparation steps of sealing conducting wire preparation, conducting wire passing, first glue sealing and second glue sealing. The conducting wire sealing bent joint has the advantages that the integral structure is compact; the occupied space is small; the preparation process is simple.

Description

technical field [0001] The invention belongs to the technical field of sealing, and in particular relates to a wire sealing elbow and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the application range of batteries is becoming wider and wider. For chemical power sources, because gas or corrosive substances may be generated inside, in order to avoid damage to the power supply system, the inside of the battery is often isolated from the outside world. This requires that the battery casing is in a sealed state, and at the same time, there is a power supply line drawn from the inside of the battery. Therefore, the sealing of the lead-out power supply line is also an important factor affecting the overall sealing performance of the battery case. [0003] In most cases, the internal lead wire of the battery is sealed by installing and sealing the solder joint plug socket and the shell, sealing the solder joint w...

Problems solved by technology

On the one hand, the lead-in and lead-out wires of the plug and socket are welded with solder joints. Since the end of the wires will harden after soldering, and the solder joints generally need to be filled with glue to ensure airtightness, so in the case of a large number of wires It is relatively difficult to bend down, and the required bending space is relatively large. For battery lead wires with limited installation space, it is bound to cause damage to the solder joints and colloid sealing performance of the wires due to too small bending radius; on the other hand, the solder joint plug socket type In the case of more lead-out wires, the volume will be larger, and with the increase of the wires, the number of solder joints will increase, and the intensive solder joint welding will have higher requirements on the welding process and welding workers.
