Abstract

The utility model relates to a terminal connector and belongs to the technical field of photoelectric or signal transmission. The connector comprises a negative pole terminal and a positive pole terminal, wherein the negative pole terminal is arranged in a negative pole base which is provided with a jack, and the positive pole terminal is arranged in a positive pole base which is provided with a plug. An elastic inserting claw is arranged on two sides of the positive pole base; an inverted hook is formed outside the end of the elastic inserting claw; a hook limit flange is arranged on two sides of a jack of the negative pole base; an elastic unlocking claw is arranged outside the hook limit flange. When the plug of the positive pole base is inserted into the jack of the negative pole base, the negative pole terminal is electrically connected with the positive pole terminal mutually, and the inverted hook forms a stop constraint on the hook limit flange; and when the elastic unlocking claw radially presses the elastic inserting claw, the inverted hook disengages from the hook limit flange for removing the stop constraint. The utility model can realize rapid assembly and disassembly so as to provide convenience for installation and replacement of the construction site.

Description

A kind of terminal connector

Technical field

The utility model relates to a kind of terminal connector that is used for industries such as new forms of energy, electronics, communication, and especially a kind of solar photovoltaic assembly terminal connector belongs to photoelectricity or signal transmission technology field.

Background technology

Solar energy power generating is a current green novel energy source technology, has obtained the concern and the attention of most of country in the world.Yet employed numerous corollary equipments all want long term exposure to work out of doors in this technology implementation process, and wherein the solar photovoltaic assembly terminal connector is one of vitals.

Understand according to the applicant, solar energy connector of the prior art comprises connector negative pole seat, negative terminal, the anodal seat of connector, positive terminal, be trapped in the negative terminal in the negative pole seat, be trapped in the positive terminal in the anodal seat, negative terminal is connected with the positive terminal assembling, and anodal seating face is stressed limited.Practice shows that the shortcoming of this type of existing structure connector is: have potential safety hazard, and be difficult to dismantle quickly and change.

The utility model content

The purpose of this utility model is: at the shortcoming that prior art exists, provide a kind of and can realize the terminal connector of attaching fast, dismounting in time, thereby facilitate for the installation of job site and replacing.

In order to reach above purpose, terminal connector of the present utility model comprises the negative terminal that is placed in the negative pole seat with jack, and is placed in the positive terminal in the anodal seat with plug; It is characterized in that: described anodal seat both sides have elasticity and insert pawl, and the outside, termination that described elasticity is inserted pawl forms barb; The jack both sides of described negative pole seat have the spacing rib of barb, and the described spacing rib outside has the elasticity releasing claw; When the plug of described anodal seat inserted the jack of negative pole seat, described positive terminal was electrically connected mutually with negative terminal, and described barb is stuck in and forms the retaining constraint on the spacing rib of barb; Radially oppress elasticity when inserting pawl when described elasticity releasing claw, described barb breaks away from the spacing rib of barb and removes the retaining constraint.

Understand easily, when the plug with anodal seat inserts the jack of negative pole seat, form the retaining constraint, therefore can guarantee that positive terminal is electrically connected with the reliable of positive terminal because elasticity is plugged in the barb of pawl.When radially oppressing the elasticity releasing claw, can remove the retaining constraint that elasticity is inserted pawl at once, thereby transfer in the jack of plug with anodal seat very easily by the negative pole seat.

This shows that the utility model can be realized quick attaching, the dismounting of terminal connector, thereby facilitate for the installation of job site and replacing.

Embodiment

Embodiment one

Present embodiment is a kind of terminal connector that is applied to solar photovoltaic assembly, and its structure comprises the positive terminal 10 that is placed in the anodal seat 2 with plug as shown in Figure 1, and is placed in the negative terminal 9 in the negative pole seat 1 with jack.Positive terminal is electrically connected with the lead to be connected of outside respectively with negative terminal.When the plug with anodal seat inserted the jack of negative pole seat, positive terminal formed with negative terminal and is electrically connected, thereby realized the electrical connection of lead.

Reliable with being connected of negative terminal in order to guarantee positive terminal, anodal seat 2 both sides have elasticity and insert pawl 16, and the outside, termination that elasticity is inserted pawl 16 forms barb (referring to Fig. 5, Fig. 6).The jack both sides of negative pole seat 1 have the spacing rib 17 of barb, and the spacing rib outside has elasticity releasing claw 13, and the termination of elasticity releasing claw 13 has weighted table 15 outwardly, and the outer surface of weighted table 15 forms asperities 14 (referring to Fig. 3, Fig. 4).As shown in Figure 2, when the plug of anodal seat 2 inserted the jack of negative pole seat 1, negative terminal 9 was electrically connected mutually with positive terminal 10, and the barb that elasticity is inserted pawl 16 terminations is stuck on the spacing rib 17 of barb, formed the retaining constraint, thereby can guarantee reliable grafting.When weighted table 15 radial forces of elasticity releasing claw 13, when compressing elasticity was inserted pawl 16, barb broke away from the spacing rib 17 of barb, removed the retaining constraint, and can extract anodal seat 2 very easily this moment from negative pole seat 1, disconnected being electrically connected.

In addition, as shown in Figure 1, in order to guarantee convenient, safety when assembling, the plug root of anodal seat 2 passes through cylindricality cervical part of esophagus 18 and the round platform section is connected with the bottom and the cylindrical portion 19 of negative pole seat 1.

Conclusion is got up, and the terminal connector of present embodiment has following remarkable advantage:

1) changed snap close between the anodal seat of existing connector and the negative pole seat, guaranteeing locking at ordinary times, for convenience detach and replacing when needing.

When 2) anodal seat is with the assembling of negative pole seat, safe ready; After anodal seat assembled with the negative pole seat, the surface linked up whole, and is attractive in appearance carefully and neatly done.

3) improved the thread depressing mechanism of the anodal seat of existing connector and negative pole seat afterbody, made that line ball end line ball is more fastening, be difficult for relatively rotating.

4) improved existing connector sealing mechanism, bowl-type line ball pawl and cylindricality sealing ring have effectively guaranteed the fastening sealing with the connector end of line ball, thereby guarantee the normal steady operation of connector.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to replaces the technical scheme that forms, and all drops on the protection range of the utility model requirement.
