The advantages of on using the first housing 11, make as detailed below：
1) deliberated index of water-proof connector classification of waterproof after waterproof test is megger test, if adjacent
Surface creepage is (such as existing connector construction) in small distance between jack, and test insulaion resistance also can be small, particularly between jack
If plastic surface it is wetly, be also easy to produce Insulation test but, judge classification of waterproof it is poor.Therefore, if by table between jack
Face creep age distance, which increases to do, to be improved, then can be increased housing monnolithic case, but this and direction high-grade, precision and advanced with connector industry hair
Exhibition is disagreed, and therefore, the overall construction design of connector will be considered, such as the connector in present embodiment, by the boss of projection
Demarcate, to form each independent boss (first boss 113, second boss 114), and have groove between each boss, so
When jack is located in each boss so that have groove between jack and jack, equal to the creep age distance for increasing surface between jack.
2) water-proof connector is when itself coordinates in addition to waterproof, can also according to customer specific requirements, its use environment occasion,
The difference of application industry needs one side (either end of male end or female end) waterproof, as mentioned in background technology：As we live
In common electric bicycle, to make lithium battery be placed on indoor charging, often battery is removed, the connector on battery is with battery
Indoor charging is brought into, and the connector on cell base, then in outdoor, sleety weather has water and drenched after connector again by battery
Electrical bad, electric car cisco unity malfunction can be produced by being placed on cell base.If one waterproof cover of increase can also solve
Certainly, but after removing battery every time need people specially to go to cover waterproof cover, can also forget to cover sometimes, inadequate hommization.
Existing terminative connector structure, terminative connector front end plane is trapped under boss, in above-mentioned environment sleety weather
Have after water drenches connector, ponding can be produced, then battery is placed on cell base can produce electrically bad, electric car can not
Normal work.Existing male end attachment structure, produced electrically bad (such as short circuit) after being equally also easy to produce ponding and ponding.
And the terminative connector 1 in present embodiment, will not as all having ponding between existing male and female terminal adapter jack,
But if any a little ponding in jack, with Male end connector 2 to inserting after, raised boss is demarcated because having, each jack is
Independent boss, there is groove between jack and jack, water will be automatically drained out.
In addition, terminative connector 1 also has waterproof gasket 17, water is not had and is penetrated into from jack inside connector or in panel
Portion, realize one side waterproof.
3) the increased connector between two pieces of panels, it is different according to use environment occasion, application industry, while Panel connector
The size of the object of place panel load, vary in weight.The strength of acted on connector is different, the company of substantially such a structure
It is all that more other types of connector application is more complicated to connect device.Connector exceeds its intensity born, and easily makes connector shell
Damage.And for housing failure, if increasing and thickening housing, and develop with the high-grade, precision and advanced direction of connector industry and disagree,
If by increase handware outside housing, its connector construction becomes more sophisticated and is unfavorable for manufacture, cost is high, therefore plate connects to plate
Connecing the intensity of device still needs structure fundamentally to ensure, while also wants profile small, low beneficial to manufacture or cost.
And the first housing 11 in present embodiment, boss is demarcated using groove, coordinated to cater to, the second housing 12
Jube 213 is added, jube 213 coordinates with groove 116, and advantage is：
A, the mating surface that jube is equal to increase male and female end housing is increased, after lifting surface area increase, connector is born strong
Degree also increases；
B, an overall boss is demarcated, coordinated with jube, connector uniform force will not be as single boss and male end
Loosened during cooperation.And there was only single fool proof mouth when the female end of single boss and the male end cooperation of no jube, it is to twist
Revolution space, discontinuity when axially rocking is fragile, and male and female end fit clearance is increasing with the extent of damage；
C, when single boss coordinates with male end, there is larger gap in centre, as above male and female end fit clearance is with the extent of damage
Increasing, according to existing connector construction, contact pin, jack are all fixed on shell, and male end is rocked with terminative connector and easily caused
Contact pin touches with the side wall of jack, jack follow the string positive force deficiency, produce loose contact, temperature rise excessively it is high electrically it is bad.
4) each boss is demarcated using groove, it can be ensured that the first shell 11 is not easy to shrink in injection molding, beneficial to manufacture.
The advantages of on using the second housing 21, make as detailed below：
1) deliberated index of water-proof connector classification of waterproof after waterproof test is megger test, if adjacent
Surface creepage is (such as existing connector construction) in small distance between contact pin, and test insulaion resistance also can be small, particularly between contact pin
If plastic surface is wetly, Insulation test is also easy to produce but, judge that classification of waterproof is poor.Therefore, if by surface between contact pin
Creep age distance, which increases to do, to be improved, then can be increased housing monnolithic case, but this develops with the high-grade, precision and advanced direction of connector industry again
Disagree.Therefore the overall construction design of connector will be considered, in present embodiment, increase jube (jube between contact pin and contact pin
213), equal to the creep age distance for increasing surface between contact pin.
2) the increased connector between two pieces of panels, it is different according to use environment occasion, application industry, while Panel connector
The size of the object of place panel load, vary in weight.The strength of acted on connector is different, the company of substantially such a structure
It is all that more other types of connector application is more complicated to connect device.Connector exceeds its intensity born, and easily makes connector shell
Damage.
Housing failure, if increasing and thickening housing, and develop with the high-grade, precision and advanced direction of connector industry and disagree, if
By increase handware outside housing, its connector construction becomes more sophisticated and is unfavorable for manufacture, cost is high, therefore board to board connector
Intensity still need structure fundamentally to ensure, while want also profile it is small, beneficial to manufacturing or cost is low.
And the second housing 21 in present embodiment, it is proposed that jube 213, jube 213 coordinate with groove 116, and advantage is：
A, the mating surface that jube is equal to increase male and female end housing is increased, after lifting surface area increase, connector is born strong
Degree also increases；
B, increase the male end of jube and the female end of with groove coordinates, connector uniform force, will not be as single boss and public affairs
End loosens when coordinating.And there was only single fool proof mouth when the female end of single boss and the male end cooperation of no jube, it is to turn round
Dynamic revolution space, discontinuity when axially rocking is fragile, and male and female end fit clearance is increasing with the extent of damage；
C, when single boss coordinates with male end, there is larger gap in centre, as above male and female end fit clearance is with the extent of damage
Increasing, according to pre-structure is improved, contact pin, jack are all fixed on shell, and male end is rocked with terminative connector and easily causes contact pin
Touched with the side wall of jack, jack follows the string, and produces loose contact, and temperature rise is excessively high electrically bad.
3) second housing 21 increases jube 213, it can be ensured that second housing 21 is more convenient for being molded in injection, beneficial to manufacture.
