Abstract
The utility model discloses a needle-type plug terminal which comprises a round bar type terminal main body, wherein the terminal main body is provided with a wiring end and an inserting end, a ring-shaped groove is formed at the wiring end of the terminal main body along the outer peripheral face of the terminal main body, and the bottom surface of the ring-shaped groove is a concave-convex surface. In the needle-type plug terminal adopting the structure, the ring-shaped groove on the terminal main body can enhance the bonding strength between the terminal main body and an insulating protector, so as to lead the plug terminal to have low possibility of dropping off, and the safety factor is improved; and since the concave-convex surface is arranged at the bottom of the ring-shaped groove, the plug can be prevented from rotating, a power cord connected to the terminal is prevented from rotating together, and the service life of the plug is prolonged.
Description
Technical field
The utility model relates to a kind of electric component, particularly a kind of Pin contact terminal.
Background technology
Plug is the power supply part that is used on the electric equipment, and plug reaches the function that transmits electricity to be accomplished through plug terminal and power line, outside plug terminal and power line, also is coated with insulation protection.But in the use of plug, usually can occur being connected not tight, loosening easily defective between the insulation protection of plug plug terminal and plug.Especially the Pin contact terminal because its cross section is circular, is difficult for fixing especially, in case plug terminal is loosening, plug terminal just comes off easily; And plug commentaries on classics also rotation easily certainly, thereby the power line that drive is connected on the terminal rotates together, and power line will break off in the course of time, has influenced the useful life of plug.
The utility model content
The technical problem that the utility model will solve is: overcome the defective that exists in the prior art, a kind of fixation is provided, be difficult for the Pin contact terminal that rotates.
In order to achieve the above object, the technical scheme of the utility model employing is:
The Pin contact terminal comprises the round bar type terminal bodies, and terminal bodies has terminals and insertion end, it is characterized in that: at the terminals of terminal bodies, along the outer peripheral face of terminal bodies annular groove is arranged, the bottom surface of annular groove is a male and fomale(M&F).A kind of optimal way as this technical scheme: the peripheral shape of the cross section of said annular groove is a gear-like.
Adopt technique scheme, the utility model has reached following beneficial effect with respect to prior art:
Annular groove on the terminal bodies can be strengthened the bond strength between terminal bodies and the insulation protection, makes that plug terminal is not easy to come off, and has improved coefficient of safety; The annular groove bottom is made as male and fomale(M&F), can stop plug to rotate, and avoids taking to the power line that is connected on the terminal and rotates together, has prolonged the useful life of plug.
Description of drawings
Fig. 1 is the structural representation of first execution mode of the utility model Pin contact terminal;
Fig. 2 is Fig. 1 along the A of dotted line to cutaway view;
Fig. 3 is the structural representation of second execution mode of the utility model Pin contact terminal.
Embodiment
Below in conjunction with accompanying drawing and preferred implementation the utility model is done further explanation.
What Fig. 1 showed is the structural representation of first execution mode of the utility model Pin contact terminal; Fig. 2 is Fig. 1 along the A of dotted line to cutaway view.As shown in Figure 1; The Pin contact terminal comprises terminal bodies 1, and terminal bodies 1 is useful on the insertion end 11 and the terminals 12 that are used to connect power line of grafting socket, at the terminals 12 of terminal bodies 1; Outer peripheral face along terminal bodies 1 has annular groove 2, and annular groove 2 bottom surfaces 21 are male and fomale(M&F).Terminal bodies 1 is provided with the device 4 that connects power line on the end face 121 of its terminals 12, for example can be copper sheet with holes etc.
When making plug, at first on terminal bodies 1, connect power line, power line is connected on the device 3 of power line after, on terminal bodies, apply insulation protection and form plug.Applied after the insulation protection, the terminals 12 of terminal bodies 1 and the device 4 that connects power line all can be insulated protection and cover.That is to say; In annular groove 2, also there is insulation protection to cover; Such structure makes insulation protection form a bayonet socket with the form fit of groove 2 at annular groove 2 places, has strengthened the bonding strength between terminal bodies 1 and the insulation protection, makes terminal bodies 1 difficult drop-off.Meanwhile; What adopted the bottom surface 21 of annular groove 2 is male and fomale(M&F); As shown in Figure 2, when the form fit of insulation protection, can stop terminal bodies 1 to be rotated at the shape at annular groove 2 places and groove 2; Avoid taking to the power line that is connected on the terminal and rotate together, prolonged the useful life of plug.
What Fig. 3 showed is the structural representation of second execution mode of the utility model Pin contact terminal, and this execution mode is a kind of improvement to first execution mode, on the end face 121 of terminal bodies 1 at its terminals 12, is provided with conductive connection sleeve pipe 3.In the time of need connecing power line, directly the power line insertion is got final product, utilize scolding tin or injection moulding fixed power source line in case of necessity.Can simplify the step that connects power line thus, also improve the coefficient of safety that power line is connected with terminal bodies 1.
Combine accompanying drawing and embodiment that the utility model has been done detailed explanation above; But the utility model is not limited to this; The technical staff in any present technique field is in the ken that is possessed; Under the prerequisite of the utility model aim, can make various modifications to the utility model.
Claims (3)
