AI Technical Summary
Existing connectors are prone to sparking in high humidity environments due to simultaneous contact between the male and female terminals, causing damage to the connector and safety hazards.
A connector is designed to prevent sparks. By setting the length of the first terminal in the slot to be longer than the second terminal, it first conducts with the third terminal to generate a magnetic field, and then multiple second terminals contact the fourth terminal, increasing the arc path length to extinguish the arc. A sealing ring, a guide structure and a locking mechanism are combined to ensure a stable connection.
Effectively prevent sparks, improve the service life and safety of connectors, avoid fire hazards, and ensure the stability and sealing of connections.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a connector capable of preventing sparks. Background Art
[0002] Current connector technology typically consists of two parts: a male connector and a female connector. The male connector is equipped with multiple male terminals, while the female connector is equipped with multiple female terminals. When the male and female connectors are plugged together, the multiple male terminals and multiple female terminals typically make contact and energize simultaneously, completing the circuit connection.

[0025] The present invention will be further described with reference to the following embodiments.
[0026] Depend on Figures 1 to 4 It can be seen that the spark-proof connector described in this embodiment includes a male socket 1 and a female socket 3 detachably connected to the male socket 1; a slot 12 is provided at one end of the male socket 1; the male socket 1 is provided with a first terminal 21 and a plurality of second terminals 22; one end of the first terminal 21 and one end of the second terminal 22 both protrude into the slot 12; the length of the first terminal 21 in the slot 12 is greater than the length of the second terminal 22 in the slot 12;
[0027] One end of the female socket 3 is provided with a boss 31; the boss 31 is provided with a first insertion hole 32 and multiple second insertion holes 33; the female socket 3 is provided with a third terminal 41 and multiple fourth terminals 42; one end of the third terminal 41 protrudes into the first insertion hole 32; one end of the fourth terminal 42 protrudes into the second insertion hole 33; the length of the third terminal 41 in the first insertion hole 32 is the same as the length of the fourth terminal 42 in the second insertion hole 33;
[0028] After the male socket 1 and the female socket 3 are plugged together, the boss 31 is inserted into the slot 12 ; the first terminal 21 is inserted into the first jack 32 ; and the second terminal 22 is inserted into the second jack 33 .
[0029] Specifically, in the connector for preventing sparks described in this embodiment, when the male socket 1 and the female socket 3 are plugged in, since the length of the first terminal 21 in the slot 12 is greater than the length of the second terminal 22 in the slot 12, the first terminal 21 is first inserted into the first jack 32 to be connected with the third terminal 41, thereby generating a magnetic field; then the multiple second terminals 22 are first inserted into the second jack 33 to contact the fourth terminal 42. Due to the existence of the magnetic field, the path length of the arc between the second terminal 22 and the fourth terminal 42 can be increased, so that the arc extinguishing process can be better performed, which can effectively prevent sparks.
[0030] In the spark-prevention connector described in this embodiment, the first terminal 21 is located at the center of the slot 12; a plurality of second terminals 22 are circumferentially distributed at equal angles around the first terminal 21. This arrangement effectively increases the arc path length between the second terminal 22 and the fourth terminal 42, thereby better extinguishing the arc and effectively preventing sparks.
[0031] In this embodiment of the spark-prevention connector, the first jack 32 is located at the center of the boss 31, and a plurality of second jacks 33 are circumferentially distributed at equal angles around the first jack 32. This arrangement effectively increases the arc path length between the second terminal 22 and the fourth terminal 42, thereby better extinguishing the arc and effectively preventing sparks.
[0032] In the spark-proof connector of this embodiment, a sealing ring 34 is provided at the bottom of the boss 31. The above arrangement can seal the male socket 1 and the female socket 3 after being plugged in.
[0033] In the spark-proof connector of this embodiment, the inner wall of the slot 12 is provided with a guide post 13 along its length, and the outer wall of the boss 31 is provided with a guide groove 35 along its length that cooperates with the guide post 13. This arrangement can guide the insertion of the male connector 1 and the female connector 3.
[0034] In the present embodiment, a connector for preventing sparks is provided with a locking cap 5 movably provided along the length direction of the outer edge of the female seat 3; a connecting platform 11 is provided at one end of the male seat 1; the slot 12 is provided inside the connecting platform 11; and the connecting platform 11 is threadedly connected to the locking cap 5. In the present embodiment, a connector for preventing sparks is provided, wherein the connecting platform 11 is sleeved inside the locking cap 5; the inner wall of the locking cap 5 is provided with an internal thread; and the outer wall of the connecting platform 11 is provided with an external thread that cooperates with the internal thread. In the present embodiment, a connector for preventing sparks is provided, wherein the bottom of the boss 31 is provided with a first blocking step 36 that abuts against one end of the locking cap 5; and the bottom of the connecting platform 11 is provided with a second blocking step 14 that abuts against the other end of the locking cap 5.
[0035] Specifically, through the above-mentioned arrangement, after the female socket 3 and the male socket 1 are plugged in, the locking cap 5 is rotated so that the locking cap 5 gradually moves toward the direction of the second blocking step 14 until the other end of the locking cap 5 abuts against the second blocking step 14. At the same time, one end of the locking cap 5 abuts against the first blocking step 36, thereby enabling the male socket 1 and the female socket 3 to be locked in the locking cap 5.
[0036] In the spark-proof connector of this embodiment, the outer wall of the male socket 1 is provided with anti-skid stripes 61. The above arrangement can play an anti-skid role when the female socket 3 and the male socket 1 are plugged in.
[0037] In the connector for preventing sparks described in this embodiment, the outer wall of the locking cap 5 is provided with anti-skid vertical lines 62. The above arrangement can play an anti-skid role when the locking cap 5 is rotated.
[0038] In the spark-proof connector described in this embodiment, a notch 7 is provided at the end of the male connector 1 away from the connection platform 11 and at the end of the female connector 3 away from the boss 31. Specifically, four notches 7 are provided. This arrangement ensures the stability of the male connector 1 and female connector 3 after injection molding, preventing the connector from falling off due to vibration or temperature rise.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
