Summary of the invention
The problem that invention will solve
As above, by making the motion about each key element such as housing, terminal, thus the pitch stricturization of connector is realized.
But when terminal group is filled to housing, sometimes there is the inserting error mistake that terminal insertion is different from the insert port that should insert inserted into the mouth in the narrow connector of pitch.Below, with reference to Fig. 5 explanation.
In housing 101, terminal (eliminating diagram) is assembled to multiple insert port 103 with narrow pitch formed connector 100, be not sometimes inserted terminals in all insert ports 103, but only at the inserted terminals that specifically inserts into the mouth.Such as, in Figure 5, assuming that in the insert port 103 of stain inserted terminals, the operating personnel of inserted terminals imagine in advance " from the left side the 3rd, the 6th, the 9th ... middle insertion " one side inserted terminals successively.But, when connector 100 be pitch narrow and small-sized, be not easy the insert port 103 that special provision should be inserted.Such as, the left side start the 3rd still can, if to the 6th, then the danger of inserting in the 5th or the 7th uprises mistakenly.
So for preventing inserting error, connector 200 is as shown in Figure 6 such, and have the motion arranging and expand pitch portion EP, it makes insert port 103 interval of every defined amount expand.Although this motion prevents effectively for inserting error, if premised on the terminal possessing equal number, be then necessary to make the width dimensions of connector 200 to become large, or if held with same width dimensions, the quantity of the terminal arranged tail off.In addition, make width dimensions comparatively large because the connector as chimeric the other side is also necessary to be engaged to connector 200, the region thus having coordinated both connector device parts to occupy becomes large, and the effect of the miniaturization of the connector that envoy causes apart from stricturization reduces.
The present invention is based on such problem and make, its object is to, providing and do not hinder pitch narrow and the housing that can prevent the electric connector of the inserting error of terminal.
For the scheme of dealing with problems
Under relevant object, the housing of electric connector of the present invention possesses: multiple terminal accommodating chamber, and it holds multiple terminal; And multiple terminal insertion mouth, it is connected with each terminal accommodating chamber and to a side opening of inserted terminals.Multiple terminal insertion mouths in the present invention, it is characterized in that comprising the 1st insert port and the 2nd insert port, part or all of the 2nd insert port periphery more projects to inserting side than the 1st insert port.
Housing of the present invention, part or all the 2nd outstanding insert port due to periphery becomes the mark of inserted terminals, so can prevent terminal insertion mistake.And the present invention makes that thus the periphery of terminal insertion mouth is outstanding does not hinder pitch stricturization, even and if the 2nd insert port outstanding be of a size of several about mm and also easily carry out and the distinguishing of the 1st insert port, thus do not make the size of the plug orientation of terminal become large yet.
In the present invention, preferably, multiple 2nd insert port configures regularly.
The operating personnel of assembling electric connector by grasping the systematicness of configuration the 2nd insert port, thus can reduce the inserting error of terminal further.
In the present invention, there is the form that multiple 2nd insert port configures regularly, can to the corresponding and configuration of selected rule of electric connector be suitable for.Most typical, when multiple terminal insertion mouth is arranged as row, the 1st insert port for every given number of configuration continuously just configures the execution mode of the 2nd insert port.Such as, for alternatively configure the 1st insert port and the 2nd insert port every one form, accompany 3 the 1st insert ports between the 2nd insert port and the form etc. that configures.
The effect of invention
According to the present invention, part or all the 2nd outstanding insert port due to periphery becomes the mark of inserted terminals, so can prevent the inserting error of terminal.And the present invention does not hinder pitch stricturization owing to making the periphery of terminal insertion mouth outstanding.

Embodiment
The present invention is explained below based on accompanying drawing illustrated embodiment.
Electric connector of the present embodiment (, only claiming connector below) 1 possesses housing 10 as depicted in figs. 1 and 2, and this housing 10 keeps omitting illustrated multiple matrix terminal 30.
Housing 10 possesses hypomere housing section 11 and is positioned at the upper casing portion 12 of upside of this hypomere housing section 11.Housing 10, is comprised hypomere housing section 11 and upper casing portion 12, is formed by the ester moulding by insulating properties.
In each in hypomere housing section 11 and upper casing portion 12, the Width X along housing 10 is provided with the terminal accommodating chamber 13 of multiple accommodation terminal 30, and terminal accommodating chamber 13 is the through hypomere housing section 11 of Y and upper casing portion 12 along the longitudinal direction.Terminal accommodating chamber 13 is Z arrangement 2 row along the vertical direction.Be arranged at the terminal accommodating chamber 13 of hypomere housing section 11 and be arranged at the terminal accommodating chamber 13 in upper casing portion 12, the configuration cycle due to Width X differs 1/2 pitch, is thus configured to staggered as a whole.Like this, by the staggered configuration of terminal accommodating chamber 13 broad ways X by upper and lower 2 row, thus the arrangement pitch stenosis of the Width X of terminal accommodating chamber 13 can be made narrow, and then make the arrangement pitch of the Width X of the matrix terminal be contained in terminal accommodating chamber 13 be narrow pitch.
Housing 10, about Width X, divides adjacent terminal accommodating chamber 13 by the partition wall 14 formed along the vertical direction.In addition, housing 10 about above-below direction Z, the partition wall 15 become by broad ways X-shaped and divide adjacent terminal accommodating chamber 13.
Housing 10 is formed with the back side place opening in hypomere housing section 11 and arrives the retainer installing hole 16 in upper casing portion 12 as shown in Fig. 2 (c).Omit illustrated retainer by installing in retainer installing hole 16, thus engaged by terminal 30, this terminal 30 is contained in each terminal accommodating chamber 13 in hypomere housing section 11 and upper casing portion 12.
In addition, on the upper surface in upper casing portion 12, the locking arm 17 of the cantilever beam-like of the housing (hereinafter, referred to the other side's housing) of the electric connector be locked to as chimeric the other side is provided with.On the front end of locking arm 17, be up provided with the latch protrusion 18 being locked in relative housing.
In addition, matrix terminal 30 possesses socket 31, as this socket of convex terminal insertion of the other side.This socket 31 has the outward appearance of cuboid, from the side inserted terminals insert port 20 of socket 31.If be connected with electric wire and matrix terminal is contained in the assigned position of the terminal accommodating chamber 13 of lower house 10 in terminal 30, then electric wire is externally drawn from terminal insertion mouth 20.If terminal 30 is contained in terminal accommodating chamber 13, then passes through once to engage mechanism, secondary locking mechanism prevents from extracting from housing 10.
So, in housing 10, each terminal accommodating chamber 13 is connected with terminal insertion mouth 20 in rear end, and when the assembling of connector 1, terminal 30 is from the side inserted terminals insert port 20 of socket 31.In present embodiment, terminal insertion mouth 20 is divided into 2 kinds.That is, as shown in Figure 1, terminal insertion mouth 20 possesses: insert port 20a, coplanar with the rear end face 19 of housing 10; And insert port 20b, more rearward give prominence to than rear end face 19.More specifically, hypomere housing section 11 and upper casing portion 12 are all alternately configured with insert port 20a and insert port 20b, and one end of X (in the drawings, is left side in the width direction.Same below) rise odd bits place be provided with coplanar insert port 20a, even bit place is provided with outstanding insert port 20b.
As in the present embodiment, by configuring regularly like this at odd bits place configuration insert port 20a (coplanar) and at even bit place configuration insert port 20b (giving prominence to), effect is below obtained.
The operating personnel of assembly connector 1, when terminal 30 is inserted housing 10 from terminal insertion mouth 20, if check the rear end face 19 of housing 10, then easily can pick out and have insert port 20a and insert port 20b these two kinds, and insert port 20a and insert port 20b alternately configures.
At this, connector 1 is not to insert in the whole terminal accommodating chambers 13 being located at housing 10, keeping terminal 30, but in order to only inserted terminals 30 in specific terminal accommodating chamber 13.Such as, assuming that below shown in case.
Case α: every (the 2nd, the 4th, the 6th) inserted terminals 30 in terminal accommodating chamber 13 alternately;
Case β: every three ground (the 3rd, the 6th, the 9th) inserted terminals 30 in terminal accommodating chamber 13;
Case γ: the 1, the 4th, the 6th ... inserted terminals 30 in arbitrary terminal accommodating chamber 13 in this wise.
About case α, although the form of terminal insertion mouth 20 is a kind of, only need skip a terminal insertion mouth 20 by matrix terminal insertion, thus the possibility of inserted terminals 30 is little mistakenly.
But, about case β, from left the 3rd still can, if but to the 6th, then insert the possibility of the 5th or the 7th terminal insertion mouth 20 (insert port 20a) mistakenly and uprise.On the other hand, if alternately configure insert port 20a and insert port 20b, add every 3 inserted terminals 30, inserting only need by the order inserted terminals 30 of coplanar insert port 20a and outstanding insert port 20b, because this can easily identify, so the possibility of inserting error diminishes.
In addition, also basic identical with case β about case γ, the form of terminal insertion mouth 20 is one species, be not easy special provision the 4th, the 6th ... the terminal insertion mouth 20 of such optional position.But, if the insert port 20a that can visually easily distinguish and insert port 20b configures regularly, so by referring to this systematicness, distinguish the 4th, the 6th mistakenly ... the possibility of the terminal insertion mouth 20 of such optional position is little, can prevent the inserting error of terminal 30.
The connector 1 of present embodiment, although distinguish insert port 20a and insert port 20b by the difference of the overhang of terminal insertion mouth 20, even if but make the outstanding size of insert port 20b comparatively large, the possibility of the effect reduction of the miniaturization of the connector also not having envoy to cause apart from stricturization.Such as, due to insert port 20b, from rear end face 19, outstanding to be of a size of about 1mm just enough, thus according to the present embodiment, the size of fore-and-aft direction Y can be made almost constant large and prevent the inserting error of terminal 30.
By the way, as shown in earlier figures 6, expand pitch portion EP if arranged, then case width size becomes large, and the miniaturization of this and electric connector is opposing.In addition, by making the wall thickness of the spaced walls 14,15 of the surrounding of zoning terminal insertion mouth 20 become large, adjacent terminal insertion mouth 20 can also be distinguished.But the connector 1 of pitch stricturization, usual terminal 30 ground very close to each other inserted terminals insert port 20, as long as thus premised on narrow pitch, regulates wall thickness just unrealistic.
In the present invention, the overhang changing terminal insertion mouth 20 is regularly not limited to the above-mentioned example alternately configuring insert port 20a and insert port 20b.Based on Fig. 3, this situation is described.In addition, Fig. 3 schematically shows the terminal insertion mouth 20 observed from rear, and the outstanding size from rear end face 19 is shown as width.Fig. 4 described later too.In addition, Fig. 3 (a) represents the example shown in Fig. 1 and Fig. 2, and the periphery of the insert port 20a coplanar with rear end face 19 represents with line, amplifies display from the width of the periphery of the outstanding insert port 20b of rear end face 19.
Such as, as shown in Fig. 3 (b), the terminal insertion mouth 20 belonging to hypomere housing section 11 configures insert port 20b every three insert port 20a, the terminal insertion mouth 20 belonging to upper casing portion 12 configures insert port 20b every two insert port 20a, thereby, it is possible to change the overhang of terminal insertion mouth 20 regularly.So, the present invention is when Z arrangement 2 arranges terminal insertion mouth 20 along the vertical direction, and the rule changing overhang also can be different by row.
In addition, in example shown in Fig. 3 (c), the terminal insertion mouth 20 belonging to hypomere housing section 11 is positioned at the position formation insert port 20b of the 3rd from two ends, other be insert port 20a, the terminal insertion mouth 20 belonging to upper casing portion 12 is only positioned at the position formation insert port 20b of central authorities, other be insert port 20a, at first sight, be trapped in the state that each section of place does not have systematicness.But, in the terminal insertion mouth 20 belonging to hypomere housing section 11 during inserted terminals 30, if reference belongs to the insert port 20b of the terminal insertion mouth 20 in upper casing portion 12, so can distinguish the order of the terminal insertion mouth 20 belonging to hypomere housing section 11.That is, be positioned at the below of the 3rd and the 4th the insert port 20a in upper casing portion 12, be positioned with the insert port 20b in hypomere housing section 11.So operating personnel by being marked by the insert port 20b in hypomere housing section 11, thus can identify the 3rd in upper casing portion 12 and the 4th insert port 20a.So, the systematicness of the overhang of the terminal insertion mouth 20 in the present invention, when arranging multiple row terminal insertion mouth 20 (terminal accommodating chamber 13) along the vertical direction, the systematicness not only in single row, can also consider the systematicness in other row adjoined.
Then, from the outstanding gamut being not limited to the periphery of rectangle insert port 20b of rear end face 19, give prominence to from rear end face 19 with also allowing the peripheral part making insert port 20b.Such as, as shown in Fig. 4 (a), the scope of about 1/2 of the periphery of insert port 20b can be made to give prominence to, as shown in Fig. 4 (b), the periphery of insert port 20b also can be made to give prominence to every predetermined distance.So, as long as the present invention operating personnel can distinguish the terminal insertion mouth 20 that periphery is outstanding, no matter and outstanding form.
Be explained above the preferred embodiment of the present invention, but only otherwise depart from purport of the present invention, just the formation enumerated in above-mentioned execution mode can be accepted or rejected, or suitably change to other formation.
Especially, the concrete formation of connector 1, housing 10 finally only shows an example, as long as corresponding with pitch stricturization, the connectors, the housing that possess other formations also can be suitable for the present invention.
In addition, in the above description, insert port 20a and the coplanar example of rear end face 19 is shown, but coplanar not necessarily key element, and as long as have the difference of outstanding size with insert port 20b, insert port 20a also can give prominence to from rear end face 19.Importantly, by producing difference of height at insert port 20a and insert port 20b, operating personnel can distinguish insert port 20a and insert port 20b.
Further, in the above description, be provided with insert port 20b regularly, but even if insert port 20b is not arranged regularly, by being marked by insert port 20b, also can alleviate the inserting error of terminal 30.
